1.0 INTRODUCTION Modern organisations are totally and irreversibly dependent on information systems in virtually every functional area. Information systems are a core enabling technology in sectors such as business, manufacturing, communications, education, health care, and government, to name just a few. This growing dependence brings fresh demands for more efficient and timely development of ever more complex systems that must be complete and correct, and that must be capable of evolution to meet changing requirements. Information and telecommunication technologies (IT) play crucial roles in the organisation and management of global businesses. In some cases information systems are enabling fundamental shifts in the structure of global markets. Recognising the importance of the link between organisations, management and information systems, all aspects of organisations are being covered in this unit while management and information systems will be covered in subsequent units. In this unit, you will be made familiar with the type of organisations and the key factors involved in the design of the organisation structures. Merits and demerits of the various organisations structures will also be discussed. You will be provided insight to the functioning and characteristics of the organisation as well as to the various stages of existence and health of the organisation.

•

appreciate the merits and demerits of tall and vertical organisation structures.

1.2 ORGANISATION AND ITS TYPES The term organisation has been defined in several ways. An Organisation can be defined as a stable, formal social structure that uses resources and produces them to 5

produce output. This output could be a physical product or service. Leavitt (1962) defined Organisation as a specific configuration of structure, people, task and techniques. Structure describes the form of departments, hierarchy and committees. It influences the organisation’s efficiency and effectiveness. People refer to the skills, attitudes and social interaction of the members of the organisation. Task refers to the goals of the individual and the organisation. Techniques refer to the methodical approach used to perform tasks. Organisational structure thus refers to the institutional arrangements and mechanisms for mobilising human, physical, financial and information resources at all levels of the system. Organisation is also defined as a system incorporating a set of sub-systems (Katz and Kahn, 1978). These sub-systems are related group of activities, which are performed to meet the objectives of the organisation. Numerous theorists have viewed organisation differently. However, all definitions usually contain five common characteristics: • • • • •

Composed of individuals and groups of individuals; Oriented towards achieving common goals; Differential functions; Intended rational coordination, and Continuity through time.

Organisations at a macro level can be divided in three types • • •

Extraction, Manufacturing including Construction, and Services.

These three types have distinct features. Extraction organisations produce goods by extracting them from the earth. Examples of such organisations are Agriculture, Mining, Oil and Gas exploration and producing companies. The manufacturing organisations produce goods by conversion or by processing of one type of goods designated as raw materials into other type of goods designated as finished goods. Examples of this type are Car manufacturing, Fertilizer manufacturing, pharmaceutical and drug manufacturing companies etc. The service organisations do not produce any tangible goods but produce services only. Services are intangible items having no shape or colour. Banking, Insurance, Transportation, Universities, Hospitals, Management Consultancy, Legal Firms etc. are example of these types of organisations. These three types of organisations have quite distinct structure, characteristics and functions. Within each of the above three macro level classification for Types of organisations, further classification is required to be based on the Industries for example, Engineering Industry, Chemical Industry, Food Industry, Banking and Finance etc. Each Industry provides its own environment, technologies, skill sets, specialisation, culture and business processes to the organisations in its ambit. Table 1 shows three basic types of organisations and various industries covered in these. It is interesting to note that sometimes three types of organisations may be part of a single Industry and may form one organisation. Steel Authority of India is one such example, which deals with not only mining and manufacturing but also trading of the product manufactured.

1.3 ORGANISATIONAL STRUCTURE An organsational structure defines how job tasks are formally divided, grouped and coordinated. It defines what are the organisational components (units), their relationships and hierarchy. It portrays where formal authority and power are located and provides a “home” and identity for employees. The knowledge about organisation structure answers to: • • • • • •

Who goes where? What do they do? What are the positions and how are they grouped? What is the reporting sequence? What is each person, and each unit, responsible for? How does authority/accountability flow?

Structure is thus an integral component of the organisation. It defines the arrangement and interrelationship of component parts and positions in an organisation. It provides guidelines on: • • • • • •

Division of work into activities; Linkage between different functions; Hierarchy; Authority structure; Authority relationships, and Coordination with the environment.

Organisational structure may differ within the same organisation according to the particular requirements. For designing an organisational structure, six key elements are required. These are: a) Work Specialisation: Historically the underlying principal was that work could be performed more efficiently if employees are allowed to specialize. Today we use the term work specialisation or division of labour, to describe the degree to which tasks in the organisation are subdivided into separate jobs. b) Departmentalisation: Once the jobs have been divided through work specialisation, these need to grouped together so that common tasks can be coordinated. The basis by which jobs are grouped together is called departmentalsation. One of the most popular ways of forming such groups is by functions like marketing, production, and finance etc. 7

Management Systems

c) Chain of command: The chain of command is an unbroken line of authority that extends from the top to lowest level and clarifies who reports to whom. It answers question for employees such as “To whom do I go if I have a problem?” and “To whom I am responsible?” d) Span of control: How many employees can a manager efficiently and effectively direct? This question of span of control is important because to a large degree, it determines the number of levels and managers an organisation has. All things being equal, the wider or larger the span, the more efficient, is the organisation. e) Centralisation and Decentralisation: The term centralisation refers to the degree to which decision-making is concentrated to a single point in the organisation. The concept includes only formal authority. Typically, if the top management makes all the key decisions, the organisation is termed as centralised. In contrast, if bulk of the decisions is allowed to be taken at the lower level, the organisation is termed as decentralised. f) Formalisation: Formalisation refers to the degree to which jobs within the organisation are standardised. In case jobs are highly formalised, employees will have less freedom or discretion to carry out the jobs, but the jobs will have explicit methods and procedures to complete it.

1.4 ORGANISATIONAL CHARACTERISTICS

Organisational Overview

The operations of nearly all organizations — from the multinational corporation to a newly opened small set-up — are based on division of labour, a decision-making structure; and rules and policies which are referred as common organisational characteristics. The degrees of formality with which these aspects of business are approached vary tremendously within the business world, but these characteristics are inherent in any business enterprise that utilises the talents of more than one person. Organisations practice division of labour both vertically and horizontally. Vertical division includes three basic levels — top, middle, and bottom. The main functions of top-managers is to draw strategic plans which may include long-term and short-term goals and also to monitor the current business with the help of middle-level managers. Middle-level managers convert the strategic plan set by top level managers into action plan and monitor day-to-day activities of lower level managers. Lower level managers act as per the action plans defined by the middle level managers and perform the specific activities as assigned to them. Organisations also divide labour horizontally by defining task groups, or departments, and assigning workers with applicable skills to those groups. Line units perform the basic functions of the business, while staff units support line units with expertise and services. In general, line units focus on supply, production, and distribution, while staff units deal mostly with internal operations and controls or public relations efforts. Decision-making structures, the second basic organisational characteristic, are used to organise authority. These structures vary from operation to operation in their degree of centralisation and decentralisation. Centralised decision structures are referred to as “tall” organisations because important decisions usually emanate from a high level and are passed down through several channels until they reach the lower end of the hierarchy. Conversely, flat organisations, which have decentralised decision-making structures, employ only a few hierarchical levels. Such organisations are typically guided by a management philosophy that is favourably disposed toward some form of employee empowerment and individual autonomy. A formalised system of rules and policies is the third standard organisational characteristic. Rules, policies, and procedures serve as templates of managerial guidance in all sectors of organisational production and behaviour. They may document the most efficient means of accomplishing a task or provide standards for rewarding workers. Formalised rules provide managers with more time to spend on other problems and opportunities and help ensure that an organisation’s various subsystems are working in concert. Poorly implemented rules, of course, can actually have a negative impact on business efforts to produce goods or services in a profitable or satisfactory manner. Thus, organisations can be categorised as informal or formal, depending on the degree of formalisation of rules within their structures. In formal organisations, say researchers, management has determined that a comparatively impersonal relationship between individuals and the company for which they work is viewed as the best environment for achieving organisational goals. Subordinates have less influence over the process in which they participate, with their duties more clearly defined. Informal organisations, on the other hand, are less likely to adopt or adhere to a significant code of written rules or policies. Instead, individuals are more likely to adopt patterns of behaviour that are influenced by a number of social and personal factors. Changes in the organisation are less often the result of authoritative dictate and more often an outcome of collective agreement by members. Informal 9

Management Systems

organisations tend to be more flexible and more reactive to outside influences. But some critics contend that such arrangements may also diminish the ability of top managers to effect rapid change. Each organisation produces some output which may be physical goods or services by use of certain inputs / resource. Resources may be one or combination of men, material, machine and finance etc. Table 2 gives the list of common characteristics of organisation. Table 2: Summary of Common and Unique Characteristics of Organisation

Common Characteristics Formal Structure Principal of Division of labour Standard Operating Procedures Decision Making Process Use of Resources (Men, Machine, Material etc.) Output

Unique Characteristics Organisational Type Environment, Goals, Power Size of the Organisation Locations Involved Functions & Business Processes Technology

The two organisations are not the same. Organisations differ greatly in type, size, function, environment, technology and business processes etc. Such characteristics, which are unique for each organisation, are listed in Table 2 Organisation Types has already been discussed Section 1.2. Organisations reside in Environment from which they draw resources and to which they provide goods or services. The effect of these environmental factors which may include stockholders, labour unions, government agencies, competitors, financial institutions, suppliers and customers (Figure 1). These factors change much faster than the organisations. For the sake of survival and profitability organisations / management have to cope and adjust to these factors and information system of the organisation plays a vital role in it. Depending upon the type of organisation and industry, each organisation has its own environment to take care of.

Suppliers

Environmental influences that affect the organisations can be categorised as either specific or general. The specific environment refers to the network of suppliers, distributors, government agencies, and competitors with which a business enterprise interacts. The general environment encompasses four influences that emanate from the geographic area in which the organisation operates. These are: • •

•

Organisational Overview

Cultural values, which shape views about ethics and determine the relative importance of various issues. Economic conditions, which include economic upswings, recessions, regional unemployment, and many other regional factors that affect a company’s ability to grow and prosper. Economic influences may also partially dictate an organisation’s role in the economy. Legal/political environment, which effectively helps to allocate power within a society and to enforce laws. The legal and political systems in which an organisation operates can play a key role in determining the long-term stability and security of the organisation’s future. These systems are responsible for creating a fertile environment for the business community, but they are also responsible for ensuring — via regulations pertaining to operation and taxation — that the needs of the larger community are addressed. Quality of education, which is an important factor in high technology and other industries that require an educated work force. Businesses will be better able to fill such positions if they operate in geographic regions that feature a strong education system.

Organisations differ, in their ultimate Goals and the type of Power used to achieve them. Some organisations have coercive goals, for example prisons; others have utilitarian goals, for example, business organisations. Still others have normative goals, for example, universities and religious groups. Size and number of locations involved for the organisations result in different organisational shape, structures and procedures. Business functions and process have been discussed in detail in Unit 2.3. Technology adopted by the organisation has great bearing on work force and tasks. Newer Technology adopted by the competitors may put strains on any organisation. The nature of Leadership differs greatly from one organisation to another — some organisations may be more democratic or authoritative than others. Some organisations perform primary Tasks that could be reduced to formal rules that require little judgment like in case of manufacturing organisations, while consultancy firms have to perform non-routine tasks. As can be seen in Table 2, list of unique characteristics is longer than the common characteristics. It stands to reason that information systems will have different impacts on different type of organisations even if the technology adopted is same. Only by close analysis and the appropriate design of the system suiting to the specific needs of the organisation will result in optimum results.

1.5 ORGANISATIONAL FUNCTIONS Let us look at a organisations whose goal is to generate certain services and/or to produce goods (factories, service enterprises, etc.). The organisational functions of such organisations is business. Now let us look at the organisations of which goal is to bring about certain effects in its surrounding world (e.g., authorities, police, political parties, interest groups, trade unions, etc.). Business is definitely not the function of these organisations. Then there are organisations whose goal is to change individuals (e.g., schools, universities, hospitals, prisons). These types of organisations are also known as non-profit-organisations and business is not the function of these organisations also. We may notice that for authorities, prison and police the function is 11

Management Systems

Bureaucracy. We may also notice that for business organisations and for bureaucratic set ups constitution, management policies, procedures and system are different to quite some extent while in the same functionality group these may be similar. There are several different Functions for various organisations. It is difficult to list down all the functions in this changing and developing scenario, however, we can look at some important organisational functions described below: a) Business organisations is an area of law that covers the broad array of rules governing the formation and operation of different kinds of entities by which individuals can organise to do business. The term is also used to describe the entities themselves. A variety of other terms are used fairly interchangeably to describe this area, including or business associations, business forms, and business entities. Reference to a “business” entity usually (though not always) indicates that entity’s status as for-profit, as opposed to non-profit. In common law countries today, the most commonly addressed forms are: • • • • • •

The sole proprietorship — this is, however, a single-person operation, and therefore not truly any kind of “organisation”. The partnership, sometimes called a “general partnership”. The limited partnership (LP). The limited liability partnership (LLP). The corporation. The limited liability company (LLC).

Less commonly used business forms include the limited liability limited partnership (LLLP), and the limited company (LC). Other types of business organisations, such as cooperatives, credit unions and publicly owned enterprises, can be established with purposes that parallel, supersede, or even replace the profit maximisation mandate of business corporations. There are large numbers of organisations in each of these forms of business. b) Bureaucracy is a concept in sociology and political science referring to the way that the administrative execution and enforcement of legal rules is socially organised. This office organisation is characterised by standardised procedure, formal division of responsibility, hierarchy, and impersonal relationships. Examples of everyday bureaucracies include governments, armed forces, corporations, hospitals, courts, ministries and schools. c) Charity is the function of the charitable trust, which is organised to serve private or public charitable purposes. Charities may take the form of charitable trusts, companies or unincorporated associations. Because of the benefits provided by charitable trusts, they are subject to certain benefits under trust law. For example, transfers of property to a charitable trust are usually exempt from the rule against perpetuities, which would otherwise operate to void a transfer made after a certain period. Furthermore, charitable trusts come under the doctrine of cypres, which holds that if the charity designated in the trust ceases to exist or otherwise becomes unable to carry out the purpose of the trust, and then the trust property can be transferred to another charity with a similar purpose. d) International Cooperation or Control is the function for the organisation of international scope or character. There are two main types of international organisations:

• •

International intergovernmental organisations (IGOs) whose members are sovereign states or other intergovernmental organisations (like, the European Union), and Non-governmental organisations (NGOs), which are private organisations.

Organisational Overview

Generally and correctly used, the term international organisation is used to mean international governmental organisations only. Examples of such organisations are: • • • • •

United Nations, its specialised agencies, and associated organisations INTERPOL International Hydrographic Organisation World Trade Organisation. Universal Postal Union.

e) Mutual Cooperation is the function for the cooperative organisation or society (which is often, but not always, a company or business) based on the principle of mutuality. A mutual organisation or society is often simply referred to as a mutual. A mutual exists with the purpose of raising funds (or money), from its membership or customers (collectively called its members), which can then be used to provide common services to all members of the organisation or society. A mutual is therefore owned by, and run for the benefit of its members — it has no external shareholders to pay in the form of dividends, and as such does not usually seek to maximize and make large profits or capital gains. Mutuals exist for the members to benefit from the services they provide. Profits made will usually be re-invested in the mutual for the benefit of the members, although some profit may also be necessary in the case of mutual to sustain or grow the organisation, and to make sure it remains safe and secure. Various types of financial institutions around the world are mutuals, and examples include: • • • • • • •

Building societies Credit unions Friendly societies (Mutual) Insurance/Assurance companies Savings and loan associations Mutual savings bank Mutual bank.

Modern mutual financial institutions usually offer services very similar (if not the same) to those of a bank, except a mutual may pay higher interest rates on savings and deposit accounts, charge lower interest rates on mortgages and loans, have fewer or lower fees and charges on the services or products it offers, and the members who save and borrow with the mutual ultimately own the business. f) Social, cultural, legal, and environmental advocacy functions from the goal of the Non-governmental organisations (NGOs). Such organisations are not part of a government and are not founded by states. NGOs are therefore typically independent of governments. Although the definition can technically include for-profit corporations, the term is generally restricted to social, cultural, legal, and environmental advocacy groups having goals that are primarily non-commercial. NGOs are usually non-profit organisations that gain at least a portion of their funding from private sources. Because the label ‘NGO’ is considered too broad by some, as it might cover anything that is non-governmental, many NGOs now prefer the term private voluntary organisation (PVO) or Private Development Organisation (PDO). 13

Management Systems

A 1995 UN report on global governance estimated that there are nearly 29,000 international NGOs. National numbers are even higher: The United States has an estimated 2 million NGOs, most of them formed in the past 30 years. Russia has 65,000 NGOs. India has 2 million NGOs. Dozens are created daily. In Kenya alone, some 240 NGOs come into existence every year. g) Collaborative Networks Function is the basis of a Virtual Organisation. A Virtual Organisation is any type of organisation that does not have a central geographical location and exists solely through telecommunication tools. •

•

A Virtual Organisation comprises a set of (legally) independent organisations that share resources and skills to achieve its mission / goal, but that is not limited to an alliance of profit enterprises. The interaction among members of the virtual organisation is mainly done through computer networks. A Virtual Organisation is a manifestation of Collaborative Networks. In business a Virtual Organisation is a firm that outsources the majority of its functions.

In grid computing, a Virtual Organisation is a group of individuals or institutions that share the computing resources of a “grid” for a common goal. h) Pacifist functions that are pacifist principles of standing against war and aggression are promoted by the Pacifist organisation. Some organisations are concerned only with the removal of nuclear weapons from war although they may call for suspension of hostilities as well. Amongst other organisations are those which deal with other concerns but which have a strong pacific element. The examples of pacifist organisations are: • Religious Society of Friends (Quakers) • Mennonites • Christian Peacemaker Teams • Christian anarchism • Fellowship of Reconciliation Nuclear pacifist organisation: • Pugwash • CND Organisations which cite pacifism as an aim: • Green peace. i) Collective function is promoted by a group of people who share or are motivated by at least one common issue or interest, or work together on a specific project(s) to achieve a common objective. Collectives are also characterized by attempts to share and exercise political and social power and to make decisions on a consensus-driven and egalitarian basis. Collectives differ from cooperatives in that they are not necessarily focused upon an economic benefit or saving (but can be that as well). A commune or intentional community, which may also be known as a “collective household”, is a group of people who live together in some kind of dwelling or residence, or in some other arrangement (eg., sharing land). Collective households may be organised for a specific purpose (eg., relating to business, parenting, or some other shared interest). Collective consciousness is a term created by French social theorist Émile Durham that describes how an entire community comes together to share similar values. The term collective is sometimes used to describe a species as a whole, for example the human collective. Types of collectives: • • 14

1.6 LIFE CYCLE OF AN ORGANISATION Organisations go through different phases of growth. For sustained growth, it is important to understand what phase of the organisational life cycle one is in. Many will enter decline unless there are transformational leaders who can renew the organisation. Different experts argue on how many phases there are in an organisational life cycle, but the Five most acceptable and distinct stages, which are easy to remember, are: 1) Startup, 2) Growth. This is sometimes divided into an early growth phase (fast growth) and maturity phase (slow growth or no growth). However, maturity often leads to. 3) Decline. When in decline, an organisation will either undergo, 4) Renewal, and 5) Failure. 15

Management Systems

Each of these phases present different management and leadership challenges that one must deal with. The Start-up Phase This phase commences from the time an entrepreneur conceives the idea of a particular business and for giving shape to the business, a management group is formed and a business plan is written. Resources are deployed and the organisation is established Start-up ends when business is declared open. The Growth Phase No organisation can remain stagnant for a long time as stagnancy for a long time leads to natural death for the organisation. So as a corollary to stagnancy, organisations to flourish must kick-start and grow. For entrepreneurs needing money to kick-start the business, the company goes into the growth phase once the investor writes the check. In the growth phase, one expects to see revenues climb, new services and products developed, more employees hired and so on. This growth phase has been divided into sub-phases of growth that is Childhood, Adolescence, Adulthood and Maturity. The management textbooks love to assume that sales grow each year. The reality is much different since a company can have both good and bad years depending on market conditions. Many companies have different types of programs relating to organisational development in place. Few actions, which need to be taken at each phase for better health of the organisation, are given in the following Table 3: Table 3: Suggested Actions for Sustained Good Health of the Organization

Stage Start-Up Phase / Birth

Characteristics An organisation is created and establishes its presence.

Actions to Take • Help develop the leadership skills of others within the organisation • Develop preliminary systems for the organisation • Invite and accept to nurture the organisational potential by more experienced leaders, organisations, and founders

Growth Phase/ Childhood

An organisation begins to learn new skills and to build a solid, supportive organisational infrastructure.

Growth Phase/ Adolescence

An organisation expands the scope of its actions and learning as it goes.

Growth Phase/ Adulthood

An organisation assumes a greater level of responsibility.

Growth Phase/ Maturity

An organisation uses its legacy to strengthen the movement overall.

• Turn over responsibility to others • Share wisdom and experiences • Set an example for personal and organisational renewal

Renewal

An organisation resists the urge to stay comfortable.

• Develop a new strategic focus or new organisational leadership

• Experiment • Take on more difficult challenges • Take responsibility for action or inaction • Learn from and be mentored by those with more experience • Take the lead on an issue even without significant credit • Take appropriate risks even if defeat is possible • Nurture and mentor organisations in their childhood and adolescence

The Decline Phase In organisations that have been around for a few years, unless checked-in by the vigilant management complacency sets in or due to other reasons / dry rots as indicated below the organisation gets into the decline phase: • • • • • • • • •

Organisational Overview

Conflicting interests between various groups / departments, leading to decisions which are not in the best interest of the organisation; Poor team work; No strategic views or strategic views not being followed; Confusing roles and responsibilities; Repeated mistakes, no lesson learned from mistakes for correcting mistakes; Fire fighting at difficult times rather than long term corrective and preventive actions; Mistrust among various groups; Executive and employees driven by greed rather than inspiring vision; No respect for resources (time, money, men or machine).

Using the above definition, one finds a tremendous amount of corporate insanity out there. Management that expects next year to be better but doesn’t know or is unwilling to change to get better results. This simple truth was shown in a 2003 study of 1900 professionals who help businesses in trouble.* Table 4: Reasons For Decline

If one can detect the symptoms of decline early, one can more easily deal with it. Some of the more obvious signs being: declining sales relative to competitors, disappearing profit margins, and debt loads which continue to grow year after year. However, by the time the accountants figure out that the organisation is in trouble, it is often too late. The Renewal Phase Decline doesn’t have to continue, however, external experts have focused on the importance of organisational development as a way of preventing decline or reducing its affects. An interesting story from Aesop’s Fables given below is worth remembering: “A horse rider took the utmost pains with his charger. As long as the war lasted, he looked upon him as his fellow-helper in all emergencies and fed him carefully with hay and corn. But when the war was over, he only allowed him chaff to eat and made him carry heavy loads of wood, subjecting him to much slavish drudgery and ill-treatment. War was again proclaimed, however, and when the trumpet summoned him to his

Management Systems

standard, the soldier put on his charger its military trappings, and mounted, being clad in his heavy coat of mail. The horse fell down straightway under the weight, no longer equal to the burden, and said to his master, “You must now go to the war on foot, for you have transformed me from a horse into an ass; and how can you expect that I can again turn in a moment from an ass to a Horse?” One way to reverse dry rot is through the use of training as a way of injecting new knowledge and skills. One can also put in place a rigorous program to change and transform organisation’s culture. Failure As many as 80% of business failures occur due to factors within the executive’s control. Even firms close to bankruptcy can overcome tremendous adversity to nurse themselves back to financial health. Lee Iacocca’s turnaround of the Chrysler Corporation is one shining example. In some cases, failure means being acquired and merged into a larger organisation. In other cases, it occurs when an organisation elects or is forced into bankruptcy. This does not signify the organisation ceases to exist since it can limp along for many years by going in and out of bankruptcy court.

1.7 VERTICAL AND HORIZONTAL ORGANISATION The structure of an organisation is the manner in which various sub-units are arranged and inter-related as discussed at Section 1.3. The organisation structure provides guidelines on hierarchy, line of authority and relationships, linkage between different functions and coordination with environment. Structure in an organisation has three important components: 1) Complexity, referring to the degree to which activities within the organisation are differentiated. This differentiation has three dimensions — • • •

Horizontal differentiation refers to the degree of differentiation between units based on the orientation of members, the nature of tasks they perform and their education and training, Vertical differentiation is characterised by the number of hierarchical levels in the organisation, and Spatial differentiation is the degree to which the location of the organisation’s offices, facilities and personnel are geographically distributed.

2) Formalisation refers to the extent to which jobs within the organisation are specialised. The degree of formalisation can vary widely between and within organisations; 3) Centralsation refers to the degree to which decision-making is concentrated at one point in the organisation. Now let us consider different types of organisation structures with merits and demerits in each of these types of structures. The grouping of employees or departmentalisation in various types of organisation structures can be based on: • 18

By product line By customer / market segment By geographical area By work flow process Combination of the above.

Organisational Overview

Function Oriented (Vertical) Organisation Structures A typical structure will look as shown in the Figure 2 The basic foundation of such organisations started from 20th century when there was lot of emphasis on specialisation during this industrial revolution era. These basic underlying principals for such formation were: • • • •

Specialization of labour Business processes were decomposed into narrower and narrower tasks Efforts were focused on improving the performance of those individual tasks Organisational units (functional departments) also reflected this narrow specialisation.

Tasks – and the organisations based on them – formed the basic building blocks of 20th century enterprises. The shortcomings in this type of structure were: • • • • • • •

Internal focus on functional goals rather than outward-looking concentration on winning customers and delivering value. Loss of important information as transactions travel up and down the multiple levels and across the functional departments. Fragmentation of performance objectives brought about by a multitude of distinct and fragmented goals. Added expense involved in coordinating the overly fragmented work and departments. Stifling of creativity and initiative of workers at lower levels. Slow responsiveness to changes in the external environment and to customer issues. Loss of sight of the totality of the business processes.

Process Oriented (Horizontal) Organisation Structures: Before we discuss Process oriented organisation structure, let us understand what is ‘process’ and how it is different from a ‘task’. • • • • 20

A task is a defined unit of work, usually performed by one person or small group. A process is a related group of tasks that together create an outcome of value to a customer. Only when all the tasks are performed together as a wholistic process the value is created. When rewards are based on task performance, the total process performance will usually be sub-optimal.

A Process oriented organisation has to be based on core processes. The core processes comprise of: • • •

Organisational Overview

End-to-end work, information and material flows. Extends across a business (and even beyond the business boundaries) and drives the achievement of fundamental performance objectives to an organisation’s strategy. Usually not more than 4 to 10 in a typical organisation, which also depends on the business strategy of the organisation.

Typical major (Core) Business Process in an organisation are: • • • • •

Order Acquisition Process transforms a sales potential into a firm order in hand. Order Fulfillment Process transforms an order into delivered goods, a satisfied customer, and the paid bill. Product Development Process transforms a customer need and/or an advanced concept into a manufacturable design that satisfies the value proposition. New Business Development Process transforms technological and conceptual advancements into new businesses. Customer Support Process transforms customer concerns and needs into valueadding solutions. Major processes are divided into sub-processes, which are then describable in terms of basic tasks or activities. Common Characteristics of Horizontally Structured Organisations are: • • • •

Core processes group employees according to the sets and scope of multiple skills needed to meet performance objectives. Teams constitute the fundamental units of the organisation and are largely self-supervised. Process owners are responsible for leading and managing the entire core processes. The primary focus is external rather than internal, emphasizing the delivery.

Management Systems

Merits of an Process based Organisation Structure are: • • • • • • •

Eliminates the numerous handoffs that occur in functionally organised companies, Facilitates a tight alignment with what the customer wants, Highly compatible with the “lean paradigm”, Fewer levels of hierarchy, reduced “overhead” effort, Facilitates agility, rapid re-configuration, as external environment changes, Performance measures and incentives/rewards can be tied more directly to tangible, measurable work progress, Enhances morale.

Vertical vs. Horizontal Organisations Process-complete departments will have shorter cycle times for the jobs only if their managers have taken steps to reduce the cycle time by cultivating a collective sense of responsibility. Means for fostering collective responsibility are: • • • •

Structure jobs with overlapping responsibilities, Arrange work areas so that people can see each other’s work, Base incentives/rewards on group performance, Design procedures so that employees with different jobs are better able to collaborate.

Restructuring by process can lead to faster cycle times, greater customer satisfaction, and lower costs, but only if the organisation has a collaborative culture as stated above. But if companies are not willing to change their culture, they may be better off leaving functional departments intact. Process oriented organisations are superior to Functional organisations for many situations, however, one size does not fit all in organisational focus. There are still many situations in which the classical vertical organisation is superior.

2.0 INTRODUCTION For successful and efficient operation of an organisation appropriate management is required is a well known fact. In the previous unit, you have learnt about organisations, their functions, structure and objectives and also learnt the commonalities of the organisations as well as how diverse requirements for their management can be there. In this unit, we will discuss how this requirement is met by understanding management functions, their hierarchical requirements and the business functionality requirements. In this unit, we will also discuss how information system requirements can be worked out to assist and help the management in discharging their various roles for successful operation of the organisation.

2.1 OBJECTIVES After going through this unit, you should be able to: •

understand the management functions at various levels of the management;

•

define the business processes;

•

work out the information system requirements of an organisation, and

•

will become familiar with the latest tools and methods for working out the information system requirements.

2.2 MANAGEMENT FUNCTIONS AND LEVELS "Management" (from Old French ménagement “the art of conducting, directing”, from Latin manu agere “to lead by the hand”) characterises the process of leading and directing all or part of an organisation, often a business, through the deployment and manipulation of resources (human, financial, material, intellectual or intangible). Early 26

twentieth-century management writer Mary Parker Follett defined management as “the art of getting things done through people.”

Management Functions and Business Processes

One can also think of management functionally, as the action of measuring a quantity on a regular basis and of adjusting some initial plan, and as the actions taken to reach one’s intended goal. This applies even in situations where planning does not take place. From this perspective, there are five management functions: Planning, Organising, Leading, Coordinating, and Controlling. Management Management is also called “Business Administration”, and schools that teach management are usually called “Business Schools”. The term “management” may also be used to describe the slate of managers of an organisation, for example, of a corporation. A governing body is a term used to describe a group formed to manage an organisation, such as a sports league. In for-profit work, the primary function of management is to satisfy a range of stakeholders. This typically involves making a profit (for the shareholders), creating valued products at a reasonable cost (for customers), and providing rewarding employment opportunities (for employees). In nonprofit work it is also important to keep the faith of donors. In most models of management, shareholders vote for the board of directors, and that board then hires senior management. Some organisations are experimenting with other methods (such as employee voting models) of selecting or reviewing managers/senior managers but this is very rare. In the public sector of countries constituted as representative democracies, politicians are elected to public office. They hire many managers and administrators, and in some countries like the United States, a great many people lose jobs when a new President comes into office. 2500 people serve “at the pleasure of the President” including all the top US government executives. Public, private and voluntary sectors place different demands on managers, but all must retain the faith of those who select them (if they wish to retain their jobs), retain the faith of those people that fund the organisation, and retain the faith of those who work for the organisation. If they fail to convince employees that they are better off staying than leaving, the organisation will be forced into a downward spiral of hiring, training, firing, and recruiting. Management also has a responsibility to innovate and improve the functioning of the organisation. In all but the smallest organisations, achieving these objectives involves a division of management and labour. People specialise in a limited range of functions so as to more quickly gain competence and expertise. Even in employee managed workplaces such as a Wobbly Shop, where managers are elected, or where latitude of action is sharply restricted by collective bargaining or unions, managers still take on roughly the same functions and job descriptions as in a more traditional command hierarchy. As has been said above management has been defined by various scholars, among them widely accepted definition by Koontz is ‘Management is the art of getting things done through and with the people in formally organised groups.’

Management Systems

Management Functions The five basic Functions, which a manager has to perform as per classical model of management, which has been accepted since 1920’s and is still popular, by early authors like Henry Fayol are: •

Planning,

•

Organising,

•

Coordinating,

•

Directing, and

•

Controlling.

To get an insight into Management let us understand these functions one by one.

Planning Planning is a process of forecasting the future in advance. From where we are it leads to where we want to be. Planning requires rigorous analysis of input, output and costs. Let us suppose we want to establish a new factory or in a factory a new product. Planning for this will require collection of basic information such as expected sales, production capacity required, types of machinery, capital, foreign exchange requirement, organisation structure required to handle various jobs etc. Since planning is to chart the future course of action, it should answer the following questions and may be a few more: •

What to do?

•

When to do?

•

Who is to do?

•

How is it to be done?

•

Where is to be done?

•

Why is to be done?

In an organisation for facilitating this planning process, goals are set, objectives are defined, policies, rules and procedures are laid down, programs are worked out, and budgets, strategies, and schedules are finalised.

Organising Organising it the process of identifying the entire job, dividing the job into convenient subjects / tasks, allocating sub-jobs to persons or group of persons and delegating authority to each so that the job is carried out as planned.

Coordinating Coordination is the process of putting the right person or group of persons at the right job. This function involves activities like defining the requirements with regard to the people for the job to be done, selecting suitable persons, training and developing them so that they can perform the desired job(s).

Directing Henri Fayol has identified the function of Directing with command. However, modern management experts are of the view that directing includes:

•

Communication,

•

Motivation, and

•

Leadership.

Directing is important because in order to achieve pre-determined goals and objectives people manning the organisation have to be guided, motivated and led by the manager.

Management Functions and Business Processes

Controlling Controlling is the Function to ensure that things are going, as they should be. Actual performance must be compared with previously set goals. If there are any significant deviations, management must take the corrective steps to bring the things on track. Thus controlling is the process that involves: • • • •

Fixing standards for measuring work performance, Measurement of actual performance, Comparing actual with standards and finding out deviations, if any, and Taking corrective actions.

To perform these functions management has to take a variety of decisions. In other words, decision-making is a fundamental pre-requisite for each of the processes talked above. As per Peter Drucker ‘Whatever a manager does, he does it through decision making’. Thus decision-making is the Essence of Management. To further understand functioning of a business organisation, let us briefly discuss the Levels of Management.

Levels of Management Managers are organisational members who are responsible for the work performance of other organisational members. Managers have formal authority to use organisational resources and to make decisions. In organisations, there are typically three levels of management: top-level, middle-level, and first-level or operational level as shown in Figure 1. These three main levels of managers form a hierarchy, in which they are ranked in order of importance. In most organisations, the number of managers at each level is such that the hierarchy resembles a pyramid, with many more firstlevel managers, fewer middle managers, and the fewest managers at the top level. Each of these management levels is described below in terms of their possible job titles and their primary responsibilities and the paths taken to hold these positions. Additionally, there are differences across the management levels as to what types of management tasks each does and the roles that they take in their jobs. Finally, there are a number of changes that are occurring in many organisations that are changing the management hierarchies in them, such as the increasing use of teams, the prevalence of outsourcing, and the flattening of organisational structures. Top Management

Middle-Management

Figure 1: Basic levels of management

Management Systems

Top-Level Managers Top-level managers, or top managers, are also called senior management or executives. These individuals are at the top one or two levels in an organisation, and hold titles such as: Chief Executive Officer (CEO), Chief Financial Officer (CFO), Chief Operational Officer (COO), Chief Information Officer (CIO), Chairperson of the Board, President, Vice president, Corporate head. Often, a set of these managers will constitute the top management team, which is composed of the CEO, the COO, and other department heads. Top-level managers make decisions affecting the entirety of the firm. Top managers do not direct the dayto-day activities of the firm; rather, they set goals for the organisation and direct the company to achieve them. Top managers are ultimately responsible for the performance of the organisation, and often, these managers have very visible jobs. Top managers in most organisations have a great deal of managerial experience and have moved up through the ranks of management within the company or in another firm. An exception to this is a top manager who is also an entrepreneur; such an individual may start a small company and manage it until it grows enough to support several levels of management. Many top managers possess an advanced degree, such as a Masters in Business Administration, but such a degree is not required. Some CEOs are hired in from other top management positions in other companies. Conversely, they may be promoted from within and groomed for top management with management development activities, coaching, and mentoring. They may be tagged for promotion through succession planning, which identifies high potential managers. Middle-Level Managers Middle-level managers, or middle managers, are those in the levels below top managers. Middle managersâ&#x20AC;&#x2122; job titles include: General Manager, Plant manager, Regional manager, and Divisional Manager. Middle-level managers are responsible for carrying out the goals set by top management. They do so by setting goals for their departments and other business units. Middle managers can motivate and assist first-line managers to achieve business objectives. Middle managers may also communicate upward, by offering suggestions and feedback to top managers. Because middle managers are more involved in the day-to-day workings of a company, they may provide valuable information to top managers to help improve the organisationâ&#x20AC;&#x2122;s bottom line. Jobs in middle management vary widely in terms of responsibility and salary. Depending on the size of the company and the number of middle-level managers in the firm, middle managers may supervise only a small group of employees, or they may manage very large groups, such as an entire business location. Middle managers may be employees who were promoted from first-level manager positions within the organisation, or they may have been hired from outside the firm. Some middle managers may have aspirations to hold positions in top management in the future. First-Level / Operational Level Managers First-level managers are also called first-line managers or supervisors. These managers have job titles such as: Office manager, Shift Supervisor, Department Manager, Foreperson, Crew Leader, Store Manager. First-line managers are responsible for the daily management of line workers â&#x20AC;&#x201D; the employees who actually produce the product or offer the service. There are first-line

managers in every work unit in the organisation. Although first-level managers typically do not set goals for the organisation, they have a very strong influence on the company. These are the managers that most employees interact with on a daily basis, and if the managers perform poorly, employees may also perform poorly, may lack motivation, or may leave the company. In the past, most first-line managers were employees who were promoted from line positions (such as production or clerical jobs). Rarely did these employees have formal education beyond the high school level. However, many first-line managers are now graduates of a trade school, or have a two-year associates or a four-year bachelor’s degree from college.

Management Functions and Business Processes

Knowledge Workers Number of organisations in today’s environment; also have another level for Knowledge Workers. Primarily, the knowledge workers are above the operational managers in the organisations. These workers deal more with Research and Development jobs and also with analysing data for Knowledge Extraction. The interaction amongst the three levels of the management can be summarized as per Jerome Kanter (1996). The Top Management, which is also known as Strategic level, establishes the policies, plans and objectives of the company as well as general budget framework of the company under which the various departments will operate. These Factors passed down to middle management, where these are translated into specific revenue, cost and profit goals. These are reviewed, analysed and modified in accordance with the overall plan and policies, until agreement is reached. Middle management then issues the specific schedules and measurement yardsticks to the operating management. The latter level has the job of producing, and / or selling of the goods and services required to meet the revenue and profit goals, which in turn will enable the company to reach its overall plans and objectives. This interaction has been shown in the following Figure 2.

2.3 BUSINESS FUNCTIONS AND PROCESSES Business Functions Business activities are grouped around functions such as production, finance and personnel, etc. resulting in department or an area of the business organisation. Each of these functional areas is interdependent and is part of the organisational system. A typical set of functions in a manufacturing organisation includes 1)

Sales and marketing,

Manufacturing and production,

Finance and accounts,

Human Resource, and

Materials Management

Information Technology now is an integral part of all business functions. Some of the main activities for each functional area have been shown in the Figure 3.

Sales and Marketing

The sales and marketing function is responsible for selling the organisationâ&#x20AC;&#x2122;s product or service. Marketing is concerned with identifying the customers for the firmâ&#x20AC;&#x2122;s products or services, determining what they need or want, planning and developing products and services to meet their needs, and advertising and promoting these products and services. Sales is concerned with contacting customers, selling the products and services, taking orders, and following up on sales. Sales and marketing information systems are required to support these activities: 32

Management Functions and Business Processes

Information systems are used in sales and marketing function in a number of ways as shown in Table 1 above. At the strategic level, sales and marketing systems monitor trends affecting new products and sales opportunities, support planning for new products and services, and monitor the performance of competitors. At the management level, sales and marketing systems support market research, advertising and promotional campaigns, and pricing decisions. They analyze sales performance and the performance of the sales staff. Knowledge-level sales and marketing systems support marketing analysis workstations. At the operational level, sales and marketing systems assist in locating and contacting prospective customers, tracking sales, processing orders, and providing customer service support. Figure 4 shows the output of a typical sales information system at the management level. The system consolidates data about each item sold (such as the product code, product description, and price) for further management analysis. Company managers examine these sales data to monitor sales activity and buying trends. The Window on Management describes some typical sales and marketing systems that might be found in a small business. PRODUCT CODE

The concept of marketing has undergone a sea change and today the traditional concept of marketing does not hold true. Whereas traditional practices of marketing start with production and consider marketing to be of use in selling and promotion to attain sales at a profit, modern marketing focuses its attention on customers / buyers. It gets profit through the creation of the buyerâ&#x20AC;&#x2122;s satisfaction and further seeks to achieve it through an integrated, corporate wide set of marketing activities. These two views have been shown in Figure 5. 33

Modern Marketing Figure 5: Traditional vs. modem marketing

Modern marketing does not remain confined to activities like advertising, selling and distribution but it also involves interaction of several other business activities with the objective of satisfying customers’ needs and aspirations. The marketing activities start with exploring and understanding customers’ need even before the product is produced, so that the product is designed keeping customers needs in mind. In case of traditional marketing, the product is produced and the product is pushed to the market with aggressive selling and promotional efforts. Some of the important functions covered in the modern marketing processes as are: Identification of the potential market: The potential market and customers are located with the target questions like: •

Where are the potential buyers located?

•

When do they buy?

•

How much they buy?

•

How frequently they buy?

•

What are the preferences of the customer for the intended product?

Identification of purchase motivation factors: Assessment is made regarding social, economic and psychological factors influencing purchases by the potential customers. The distribution and transportation factors: are reviewed to optimization cost by integrating movement and warehousing. Product design adjustment factors: Based on the preferred products in the market, product design is reviewed. Communication factors: Advertising, personal selling, sales promotion, publicity and packaging are reviewed to enable most optimum communication to the customer. 34

Transaction functions: Order booking, invoicing, billing, credit realisation etc. are reviewed to make them more customer friendly.

Management Functions and Business Processes

Post-transaction factors: After sales service is given due attention to ensure repeated purchases by the customers. The marketing information system, which can provide assistance / support to correct decision is very important for success of all above factors.

2.3.2

Manufacturing and Production

The manufacturing and production function is responsible for actually producing the firmâ&#x20AC;&#x2122;s goods and services. Manufacturing and production systems deal with the planning, development, and maintenance of production facilities; the establishment of production goals; the acquisition, storage, and availability of production materials; and the scheduling of equipment, facilities, materials, and labour required to produce the finished products. Manufacturing and production information systems support these activities. Table 2 shows some typical manufacturing and production information systems arranged by organisational level. Strategic-level manufacturing systems deal with the firm long-term manufacturing goals, such as where to locate new plants or whether to invest in new manufacturing technology. At the management level, manufacturing and production systems analyse and monitor manufacturing and production costs and resources. Knowledge manufacturing and production systems create and distribute design knowledge or expertise to drive the production process, and operational manufacturing and production systems deal with the status of production tasks.

Quality Control, Environmental Control and Safety are the other factors, which are required to be controlled as part of present day Production Functions. More and more organisations are going in for International Standards (ISO 9000 for Quality, ISO14000 for Environment). These standards require control of raw material, equipment maintenance and performance in an integrated manner, which is possible only through good information system and analysis.

2.3.3

Finance and Accounts

The finance function is responsible for managing the firmâ&#x20AC;&#x2122;s financial assets, such as cash, stocks, bonds, and other investments, in order to maximize the return on these financial assets. The finance function is also in charge of managing the capitalisation of the firm (finding new financial assets in stocks, bonds, or other forms of debt). In order to determine whether the firm is getting the best return on its investments, the finance function must obtain a considerable amount of information from sources external to the firm. 35

Management Systems

The accounting function is responsible for maintaining and managing the firm’s financial records — receipts, disbursements, depreciation, payroll — to account for the flow of funds in a firm. Finance and accounting share related problems — how to keep track of a firm’s financial assets and fund flows. They provide answers to questions such as: What is the current inventory of financial assets? What records exist for disbursements, receipts, payroll, and other fund flows?

Table 3 shows some of the typical finance and accounting information systems found in large organisations. Strategic-level systems for the finance and accounting function establish long-term investment goals for the firm and provide long-range forecasts of the firm’s financial performance. At the management level, information systems help managers oversee and control the firm’s financial resources. Knowledge systems support finance and accounting by providing analytical tools and workstations for designing the right mix of investments to maximize returns for the firm. Operational systems in finance and accounting track the flow of funds in the firm through transactions such as paychecks, payments to vendors, securities reports, and receipts.

2.3.4

Human Resource

The human resources function is responsible for attracting, developing, and maintaining the firm’s workforce. Human resources information systems support activities such as identifying potential employees, maintaining complete records on existing employees, and creating programs to develop employees’ talents and skills. Strategic-level human resources systems identify the support requirements (skills, educational level, types of positions, number of positions, and cost) for meeting the firm’s long-term business plans. At the management level, human resources systems help managers monitor and analyse the recruitment, allocation, and compensation of employees. Knowledge systems for human resources support analysis activities related to job design, training, and the modelling of employee career paths and reporting relationships. Human resources operational systems track the recruitment and placement of the firm’s employees (see Table 4). Figure 6 illustrates a typical human resources record keeping. It maintains basic employee data, such as the employee’s name, age, sex, marital status, address, educational background, salary, job title, date of hire, and date of Training. The system can produce a variety of reports, such as lists of newly hired employees, Areas in which employees have been trained etc. employees are classified by job type or educational level, or job performance evaluations. Such systems are typically designed to provide data that can satisfy income tax, Provident fund and other statutory requirements and record keeping requirements for Equal Employment Opportunity (EEO) and other purposes.

Materials Management

The materials management function is responsible for procurement of raw materials and other items like plant and equipment and spare parts etc. For typical manufacturing companies about 50-70 % of the total cost is on account of materials. Therefore, for continued successful operation of any organisation in the competitive environment, good materials management and information system is very important. Information system is required because materials management is more dependent on flow of information. Strategic level system for materials management identifies long 37

Inventory system is essential for most of the manufacturing and production systems. As illustrated in Figure 7, data about each item in inventory, such as the number of units depleted because of a shipment or purchase or the number of units replenished by reordering or returns, are either scanned or keyed into the system. The inventory master file contains basic data about each item, including the unique identification code for each item, the description of the item, the number of units on hand, the number of units on order, and the reorder point (the number of units in inventory that triggers a decision to reorder to prevent a stock out). Companies can estimate the number of items to reorder or they can use a formula for calculating the least expensive quantity to reorder called the economic order quantity. The system produces reports such as the number of each item available in inventory, the number of units of each item to reorder, or items in inventory that must be replenished.

Business Processes A Business Process is best defined as any function within an organisation that enables the organisation to successfully deliver its products and services. A simple analogy would be to look at an organisation as a wheel and the individual Business Processes are the spokes to the wheel. Having just one or two spokes loose can make a wheel out-of-balance. The longer a wheel runs out of balance the more damaging the effect to the organisation. When the wheel on a cart becomes so unstable that its primary function fails, you would simply replace the wheel. Obviously, an organisation cannot simply replace itself... but your customer can and will replace the wheel (you the Supplier) if you fail to perform to the customers’ needs and expectations. Obviously, this is a very simplistic and extreme analogy about the operation of an organisation. But, when you step back and look at the products and services you purchase yourself, it actually becomes a little more understandable. You wouldn’t maintain a business relationship with a supplier if the suppliers’ own internal Business Processes prevented the supplier from performing its best. You would probably go to another supplier.

Management Functions and Business Processes

A Business processes can be defined as a unique manner in which work is organised, coordinated, and focused to produce a valuable product or service. On the one hand, business processes are concrete workflows of material, information, and knowledge– sets of activities. On the other hand, business processes represent unique ways in which organisations coordinate work, information, and knowledge, and the ways in which management chooses to coordinate work. Table 6 describes typical business processes for each of the functional areas. Table 6: Functional Area and Business Processes

Although each of the major business functions has its own set of business processes, many other business processes are cross-functional, transcending the boundaries between sales, marketing, manufacturing, and research and development. These crossfunctional processes cut across the traditional organisational structure, grouping employees from different functional specialties to complete a piece of work. For example, the order fulfilment process at many companies requires cooperation among the sales function (receiving the order, entering the order), the accounting function (credit checking and billing for the order), and the manufacturing function (assembling and shipping the order) as shown in Figure 8. 39

Organisational structure throughout the many diverse industries varies, but for the most part, all organisations perform similar Business Processes. Whether you are from a large or small corporation, government agency, or a non-profit association, to a large extent, you share common Business Processes with other industries. The Business Process of Human Resources for one industry can be very similar to another. In fact, the Human Resource Business Processes may even be a Critical Success Factor for some of the industries. Today ready-made solutions for Common Business Processes are available, which require little bit of customisation for using in variety of organisations.

2.4 INFORMATION SYSTEMS REQUIREMENTS At the turn of the nineteenth century industrial revolution took place. This Industrial Age focused on the role of the Management. At present with the rapid development of the Information Technology, a new industrial revolution is in the making, similar to the one that took place at the turn of the nineteenth century. The world is advancing from the Industrial Age to the knowledge age. The new challenge to the management which surrounds us requires profound change; profound change in the way we consider the organisations; may be those are part of the Government or civil administration or business enterprise, the way we develop our businesses, the way we manage, and the structures within which we manage. Productivity and efficiency of business to reduce cost of products and services, and to use technology to continually innovate is nothing new except that the competition is much more fierce than ever before. Globalisation of the marketplace, and means of accessing the same, through national and global information superhighways have given a new dimension to the concept of information. Information and knowledge are critical to mange change, which is the salient feature of the Information Age. Businesses do not have sufficient time to consolidate as there are continuous changes to be handled due to changes in technology, raw materials, customer needs, legislation, rule and regulations. 42

Information Age is thus knowledge-based. This challenge of providing rapid changing information and thus knowledge base requires a system. As we see thus this Information Age requires focus on Management and the Information Systems, therefore, we will focus on how the information system needs of the management can be fulfilled.

Management Functions and Business Processes

Information Information is a necessary and vital input for the Management. Any Management decision-making has to be based on information. Information need to be TRUE. Making use of its acronym we may say information must be Timely, Reliable, Useful, and Explicit. Timely: It should reach the recipient in time and up-to-date. For effective decision making information must reach the decision maker at the right time so that he can take the desired action. The delayed information at times can even lead to loss of purpose itself or in substantial loss. Reliable: Any information can be reliable only if it is factual, accurate and complete. Useful: Relevance and adequacy of the information for the need for which it is required makes it useful to purpose. Explicit: Quality information is said to be explicit if it does not require further analysis by the recipient for decision-making. In other words information can be defined as processed data.

System In our everyday life, the word â&#x20AC;&#x2DC;systemâ&#x20AC;&#x2122; is used quite often. We talk about an educational system, computer system, organisational system, political system, solar system, railway system etc. On analysis we will find we use the word system to mean a collection of elements integrated to achieve a common definable goal. For illustration, a business organisation can be considered as a system, in which the parts (departments, sections and units etc.) are joined together for a common goal. An information system can be a set of collection of elements starting from collection of data, its processing and presentation for achieving a defined or set goal.

2.5 REQUIREMENT ANALYSIS Requirements analysis, in software engineering, is a term used to describe all the tasks that go into the instigation, scoping and definition of a new or altered computer system. Requirements analysis is an important part of the software engineering process; whereby business analysts or software developers identify the needs or requirements of a client; having identified these requirements they are then in a position to design a solution. Requirements analysis is also known under other names: •

requirements engineering

•

requirements gathering

•

requirements capture

•

operational concept documenting

•

systems analysis

•

requirements specification.

During most of the history of software engineering it has been considered to be a relatively easy part of the process. However, in the last decade or so, it has become increasingly recognised as being the most vital part of the process; given that the failure to properly identify requirements makes it virtually impossible for the finished piece of software to meet the needs of the client or be finished on time. The challenge Successfully completing a “requirements analysis” task is a challenge. In the first place, it is not easy to identify all the stakeholders, give them all an appropriate form of input, and document all their input in a clear and concise format. And there are constraints. The requirements engineer is expected to determine whether or not the new system is • • • • •

feasible schedulable affordable legal ethical.

In the rush of enthusiasm associated with a new project, there is always a temptation to downplay the importance of requirements analysis. However, studies of various projects reveal that costs and technical risks can be reduced through rigorous and thorough up-front requirements engineering. General problem The general difficulties involved with requirements analysis are increasingly well known:

•

the right people with adequate experience, technical expertise, and language skills may not be available to lead the requirements engineering activities;

•

the initial ideas about what is needed are often incomplete, wildly optimistic, and firmly entrenched in the minds of the people leading the acquisition process; and

•

the difficulty of using the complex tools and diverse methods associated with requirements gathering may negate the hoped for benefits of a complete and detailed approach.

Management Functions and Business Processes

Stakeholder issues Steve McConnell, in his book Rapid Development, details a number of ways users can inhibit requirements gathering: • • • • • • •

Users don’t understand what they want. Users won’t commit to a set of written requirements. Users insist on new requirements after the cost and schedule have been fixed. Communication with users is slow. Users often do not participate in reviews or are incapable of doing so. Users are technically unsophisticated. Users don’t understand the software development process.

This commonly leads to the situation where user requirements keep changing even when the software development has been started. Because new requirements may sometimes mean changing the technology as well, the importance of finalising user requirements before the commencement of development should be made very clear to the Business Users. Knowing their objectives and expectations regarding the solution beforehand and documenting agreed requirements is fundamental to the success of a project. Developer issues However, developers are often equally at blame. Typical problems caused by software developers are: •

Software developers and end users often have different vocabularies. Consequently, they can believe they are in perfect agreement until the finished product is supplied. The duty to bridge that gap is often assigned to Business Analysts, who analyse and document the business processes of business units affected by the proposed business solution, and Business Systems Analysts, who analyse and document the proposed business solution from a systems perspective.

•

Software developers often try to make the requirements fit an existing system or model, rather than develop a system specific to the needs of the client.

•

Analysis is often carried out by programmers, rather than business analysts. It is often the case that programmers lack the people skills and the domain knowledge to understand a business process properly.

•

Software developers have pre-conceived notions about the problem.

Solutions One of the solutions to these problems are to recognise that requirements analysis is a specialist field best carried out by experts, i.e. business or system analysts, who could bridge the gap between the business and IT (Information Technology) world. While this approach has helped, it has often been difficult to find staff who possess equally good people and technical skills. In addition, the techniques used to analyse requirements have not proven sufficiently effective in all situations. Techniques introduced in the 1990s like Prototyping, Unified Modeling Language (UML), Use 45

Management Systems

cases, and Agile software development are often put forward as a promising solution to this issue. More recently, however, attempts have been made to address these difficulties with the establishment of the International Institute of Business Analysis, whose main goals are the creation of a common Body of Knowledge for Business Analysis, and to use it as basis for certification of Business Analysis Professionals.Also, a new class of application simulation or application definition tools have entered the market. These tools are designed to bridge the communication gap between business users and the IT organisation — and also to allow applications to be ‘test marketed’ before any code is produced. The best of these tools offer: • • • • • •

electronic whiteboards to sketch application flows and test alternatives ability to capture business logic and data needs ability to generate high fidelity prototypes that closely imitate the final application interactivity capability to add contextual requirements and other comments ability for remote and distributed users to run and interact with the simulation.

2.6 TOOLS AND METHODS FOR REQUIREMENT ANALYSIS Requirements analysis can be a long and arduous process. The requirements specialists do their work by talking to people, documenting their findings, analysing the collected information to discover inconsistencies and oversights, and then talking to people again. This process can go on for anywhere from a week to a year or more, and may continue throughout the life cycle of a system. New systems change the environment and relationships between people, so it is important to identify all the stakeholders, take into account all their needs and ensure they understand the implications of the new systems. Frequently, this objective is not met because: • •

there is not enough communication up front and important needs are overlooked when the system is implemented; and/or there is not enough ongoing communication during system development and the users are disappointed by the new system’s characteristics.

To keep all these discussions well organised and efficient, the evolving requirements must be documented. Analysts can employ several techniques to get the requirements from the customer. Historically this has included such things as holding interviews, or holding focus groups (more aptly named in this context as requirements workshops — see below) and creating requirements lists. More modern techniques include Prototyping, and use cases. Where necessary, the analyst will employ a combination of these methods to establish the exact requirements of the stakeholders, so that a system that meets the business needs is produced. Methods for Requirement Analysis: Stakeholder interviews Stakeholder interviews are obviously necessary in requirement specification. However, in any large system a number of individuals need to be interviewed which 46

increases the time and cost. This often leads to pressure to shorten the analysis phase despite the impact incomplete requirements can have on a project. Stakeholder interviews also often reveal major shortcomings with regard to how existing business processes works and identify how to improve this in the future. While this is ultimately a positive for the business, it will also lead to previously unforeseen increases in time and cost. This can be further compounded by the discovery that different users have differing or even contradictory requirements.

Management Functions and Business Processes

Requirement workshops To overcome these issues, where systems are complex the usual method is to conduct requirement workshops. The analyst brings the main stakeholders in the system together in order to analyse the system and develop the solution. These workshops are more properly termed Joint Requirements Development (JRD) sessions, where requirements are jointly identified and defined by stakeholders. Such workshops are ideally carried out in a controlled environment, so that the stakeholders are not distracted. A facilitator can be used to keep the process focused and these sessions will often benefit from a dedicated scribe to document the discussion. Facilitators may make use of a projector and diagramming software or may use props as simple as paper and markers. Often multiple workshops are required to bring the process to a successful conclusion. Requirements workshops are considered to be a very useful technique which can save significant time. However, it can be hard to get all the required stakeholders together at one time. A more general weakness is that some stakeholders do not contribute forcefully enough in workshops and their requirements will not receive the appropriate attention, inevitably producing a limited solution. Additionally, while requirement workshops are an excellent technique for modelling the existing system, they are not so useful for defining the nature of the solution. Contract-style requirement lists One way of documenting requirements has been contract style requirement lists. In a complex system such requirements lists can run to hundreds of pages. An appropriate metaphor would be an extremely long shopping list. Such lists are very much out of favour in modern analysis; as they have proved spectacularly unsuccessful at achieving their aims; but they are still seen to this day. Strengths: • • •

Provides a checklist of requirements. Provide a contract between the project sponsor(s) and developers. For a large system it can provide a high level description.

Weaknesses: • •

Such lists can run to hundreds of pages. It is virtually impossible to read such documents as a whole and have a coherent understanding of the system. Such requirements lists abstract all the requirements and so there is little context o o o

This abstraction makes it impossible to see how the requirements fit together. This abstraction makes it difficult to identify which are the most important requirements. This abstraction means that the more people who read such requirements the more different visions of the system you get.

Management Systems

This abstraction means that it’s extremely difficult to be sure that you have the majority of the requirements. Necessarily, these documents speak in generality; but the devil, as they say, is in the details. These lists create a false sense of mutual understanding between the stakeholders and developers. These contract style lists give the stakeholders a false sense of security that the developers must achieve certain things. However, due to the nature of these lists, they inevitably miss out crucial requirements which are identified later in the process. Developers use these discovered requirements to renegotiate the terms and conditions in their favour. These requirements lists are no help in system design, since they do not lend themselves to application. o

• •

•

Prototypes In the mid-1980s, prototyping became / seen as the solution to the requirements analysis problem. Prototypes are mock ups of the screens of an application which allow users to visualize the application that isn’t yet constructed. Prototypes help users get an idea of what the system will look like, and make it easier for users to make design decisions without waiting for the system to be built. When they were first introduced the initial results were considered amazing. Major improvements in communication between users and developers were often seen with the introduction of prototypes. Early views of the output led to fewer changes later and hence reduced overall costs considerably. However, over the next decade, while proving a useful technique, it did not solve the requirements problem: •

Managers once they see the prototype have a hard time understanding that the finished design will not be produced for some time.

•

Designers often feel compelled to use the patched together prototype code in the real system, because they are afraid to ‘waste time’ starting again.

•

Prototypes principally help with design decisions and user interface design. However, they can’t tell you what the requirements were original.

•

Designers and end users can focus too much on user interface design and too little on producing a system that serves the business process.

Prototypes can be flat diagrams (referred to as ‘wireframes’) or working applications using synthesized functionality. Wireframes are made in a variety of graphic design documents, and often remove all colour from the software design (i.e. use a greyscale colour palette) in instances where the final software is expected to have graphic design applied to it. This helps to prevent confusion over the final visual look and feel of the application. Use cases A use case is a technique for capturing the potential requirements of a new system or software change. Each use case provides one or more scenarios that convey how the system should interact with the end user or another system to achieve a specific business goal. Use cases typically avoid technical jargon, preferring instead the language of the end user or domain expert. Use cases are often co-authored by software developers and end users. Use cases are deceptively simple tools for describing the behaviour of the software. A use case contains a textual description of all of the ways that the intended users could 48

work with the software through its interface. Use cases do not describe any internal workings of the software, nor do they explain how that software will be implemented. They simply show the steps that the user follows to use the software to do his work. All of the ways that the users interact with the software can be described in this manner.

Management Functions and Business Processes

During the 1990s use cases have rapidly become the most common practice for capturing functional requirements. This is especially the case within the objectoriented community where they originated, but their applicability is not restricted to object-oriented systems, because use cases are not object oriented in nature. Each use case focuses on describing how to achieve a single business goal or task. From a traditional software engineering perspective a use case describes just one feature of the system. For most software projects this means that multiple, perhaps dozens, of use cases are needed to fully specify the new system. The degree of formality of a particular software project and the stage of the project will influence the level of detail required in each use case. A use case defines the interactions between external actors and the system under consideration to accomplish a business goal. Actors are parties outside the system that interact with the system; an actor can be a class of users, roles users can play, or other systems. Use cases treat the system as a “black box”, and the interactions with system, including system responses, are as perceived from outside the system. This is deliberate policy, because it simplifies the description of requirements, and avoids the trap of making assumptions about how this functionality will be accomplished. A use case should: • • •

describe a business task to serve a business goal be at the appropriate level of detail be short enough to implement by one software developer in single release.

Use cases can be very good for establishing the functional requirements; however they are not suited to capturing Non-Functional Requirements. Software Requirements Specification A software requirements specification (SRS) is a complete description of the behaviour of the system to be developed. It includes a set of use cases that describe all of the interactions that the users will have with the software. In addition to use cases, the SRS contains functional requirements and nonfunctional requirements. Functional requirements define the internal workings of the software: that is, the calculations, technical details, data manipulation and processing, and other specific functionality that shows how the use cases are to be satisfied. Nonfunctional requirements impose constraints on the design or implementation (such as performance requirements, quality standards, or design constraints). Stakeholder identification A major new emphasis in the 1990s was a focus on the identification of stakeholders. This first step is now seen as critical. In the early days systems were built for the projects sponsor(s), who were usually management types. Many systems have been designed by managers with little or no contributions from the eventual users; these systems have tended to fail horrendously. So within the field of software engineering, in the 1970s and 1980s, the understanding of the term stakeholder widened to the main users of the system, and then peripheral users. However, since the 1990’s the search for stakeholders is taking on a more whole system approach. It is increasingly 49

Management Systems

recognised that stakeholders do not just exist in the organisation the analyst is hired by. Other stakeholders will include: • • •

those organisations that integrate (or should integrate) horizontally with the organisation. any back office systems or organisations. higher management.

Successful identification of the stakeholders ensures that analysis will take into account the right elements. Tools for Requirement Analysis Use of proper tools for requirement analysis helps in avoiding rework, which typically accounts for 40% of a development organisation’s total spend — time, and money that organisations cannot afford in today’s highly competitive business landscape. Most of this rework effort focuses on correcting requirements defects, which could cost 50 to 200 times as much as defects that, are corrected close to the point of creation. It is important for IT organisations to deliver software Requirements Definition and Management Solution at less cost by getting requirements right the first time and ensuring business IT alignment throughout the software lifecycle. In addition the approach needs to be that it takes into account an organisation’s process maturity and leverages industry best practices to evaluate current performance and identify specific areas for improvement. The tool should provide a scalable, integrated Software Requirements Definition and Management solution that enables IT organisations to: Define: Produce accurate and complete requirements by eliciting, specifying, analysing, and validating requirements early, reducing costly rework later in the development lifecycle. Manage: Deliver the right product the first time, every time by tracking progress, communicating changes and focusing resources. Verify: Ensure quality by tracing requirements though implementation to testing. The tool should help organisations answer the following key questions: How can we define accurate and complete requirements? How can we document or specify requirements to communicate them without ambiguity? How can we perform impact analysis and prioritisation on changing requirements? How can we effectively manage project scope? Process-Led Approach for Improving Software Requirements Definition and Management.

Analysis To ensure the most important business requirements are delivered, steps need be taken so that organisations mature their existing analysis process by: • • •

Implementing an effective approach for evaluating and prioritising requirements, Enhancing the skills of analysts for analysing and clarifying requirements, and Enabling a robust, requirements-based estimation and planning process.

IT organisations deliver increased value to business stakeholders based on greater alignment between business and IT, while business stakeholders deliver more value to their customers because priorities are aligned with IT. The organisation also gains better estimation and thus, improved predictability of system deliveries. 51

Specification To improve accuracy and relevancy, organisations may mature their existing requirements specification process by: • • •

• • • • •

Defining a consistent hierarchy of requirement types, attributes and traces, so all stakeholders can easily find, filter and sort on the most relevant data, Developing standard templates for each requirement scenario to ensure completeness, Identifying various specification techniques (e.g., use case models, business process models, prototypes, and traditional requirements specifications) and their appropriate use so that requirements are captured in a meaningful, easy-tounderstand way, Configuring a tools infrastructure to support custom templates and integrations, Training development teams in the appropriate use of the tools, Providing automated trace ability across the various requirements types, Training team members to leverage traces throughout the lifecycle to achieve overall project control, and Leveraging selected technology to detail requirements with attributes, trace ability, screenshots, images, office documents and more to make requirements clear and understandable to drive development most effectively.

Validation To improve accuracy and completeness, organisations may mature their existing requirements validation process by: • • •

Defining and implementing a verification process with clear quality metrics to reduce defects, Automating validation and verification processes through the storyboard execution to drive process adoption and enforcement and improve consistency and quality, and Defining and implementing a process for validating requirements with stakeholders that ensures requirements signoff.

Management To maximize responsiveness and control, organisations may mature their existing requirements management process by: • •

Establishing processes for managing changes to existing requirements, including a standard process for requesting changes to enable better control of scope and commitment, improved impact analysis and more reliable project planning, and Defining procedures for evaluation and acceptance among stakeholders — in some cases establishing a Change Control Board.

With the use of the appropriate tool, organisations are expected to improve their ability to handle ongoing changes, maximizing business impact, while minimizing schedule and scope impact, gain greater ability to manage the ever-increasing requests from business teams in a collaborative, factual way, and increase business stakeholder satisfaction because development is more responsive, delivering the right software on time and within budget. Requirement Analysis Tools Large numbers of Requirement analysis tools are available commercially as can be seen in the following list (in alphabetical manner). This list also indicates the suppliers of these tools as well as the Salient features of the tools have been described. 52

Accept 360° from Accept Software Corporation is a requirements management tool that also supports product planning. Tools help users to define and track feature dependencies with tree diagrams, and to relate these to the market, project plans, implementation considerations and competitor analyses.

Active Focus from Xapware supports the software application life cycle. Agility from Agile Edge is a tracking database for user requirements, issues, tasks and bug tracking, permitting tracing between these items. There is a simple user interface displaying a table of items with status, symbols and text. AnalystPro from Goda Software supports requirements editing and trace ability, change control, diagrams including use cases, and other features of full RM tools at a low price per seat. Kris of Goda Software, Inc: Analyst Pro is an affordable, scalable and collaborative tool for requirements tracking, trace ability analysis and document management. It is easily deployable and customizable to the project needs.” Caliber-RM from Borland is a well-known requirements management tool. It is intended for large and complex systems, and provides a database of requirements with trace ability. This tool views requirements as part of the software quality management process, which it considers and also includes testing and defect tracking. Caliber is Internet-based, and it handles document references, user responsibility, trace ability, status and priority. Chip Carey of Starbase (former owners of Caliber): “The exciting thing about RM and Caliber RM in particular is that it brings all departments together within the software development lifecycle and puts them all on the same page — it provides a mechanism for communication and collaboration and effectively provides a synergy where before they were perhaps separate efforts and maybe counter-productive.” C.A.R.E. from Sophist Group is a Lotus Notes-based tool which provides a databaselike view of requirements. The website is in German but the tool’s GUI is in English. Using the hypertext-like Lotus Notes is an interesting approach to organising requirements with obvious practical advantages, and the Sophist Group is noted for its Object-Oriented thinking. The tool provides a wide range of features and produces both textual and graphical outputs. Cradle from 3SL Cradle is a multi-user, multi-project, distributed and web-enabled requirements management and systems engineering environment. It is intended for all sizes of requirements and systems development projects. Cradle can link to corporate PDM/EDM systems. It offers configuration management, edit histories and version control. It automates document production and can manage the generated documents. Through its web interface, it can integrate disparate stakeholder groups by creating customizable read-write portals to all project data. Mark Walker of 3SL Cradle can deliver unlimited requirements and systems modeling scalability to the desktop through web and non-web methods that allow capture and parsing of requirements and their traceability through every part of all C4ISR, ISO, DoD and INCOSE recommended processes. Clear Requirements Workbench (CRW) from LiveSpecs Software helps specify, verify, and manage detailed requirements. CRW supports four detailed specification techniques (glossaries, action contracts, test procedures, and precise use cases) for the clear description of definitions, behaviour, and usage. David Gelperin of LiveSpecs Software: Clear Requirements Workbench is the first system to actively support the detailed requirements that put customers, users, managers, marketers, developers, testers, and technical writers on the same page.

DocuBurst from Teledyne Brown Engineering is a package that discovers requirements and headings in text documents, and structures them into objects for use in requirements and other tools. It runs on Windows, and generates XML, TSV, CSV, and other file types. It is compatible with most tools including TBE’s own XTie-RT. Sherry Adlich Using DocuBurst to ‘burst’ a text document into pieces eliminates days of effort typically spent to analyse documents for information gathering or requirements gathering. Doors from Telelogic Doors is a tool primarily for large organisations which need to control complex sets of user and system requirements with full trace ability. It provides good visualization of such documents as hierarchies, and its extension language enables a wide range of supporting tools to be built, and many are provided as menu commands and examples. Further options include DoorsNet which allows controlled interaction over the Internet, and the Change Proposal System which automates the requirement review cycle. There are live interfaces to many CASE tools, and the promise of tight integration with Telelogic’s market-leading Tau toolkit for specification, design, and testing based on UML and the SDT approach to realtime systems development centred on telecommunications. Its use is therefore moving towards integrated project support. Nancy Rundlet of Telelogic says: With DOORS, we provide worldwide support, Word-like ease of use, scalability from 1 user to several hundred, and ease of establishing traceability and displaying it to multiple levels. Focal Point (now owned by Telelogic) is a market-driven requirements management tool. It incorporates customer collaboration, prioritization and visualization and decision-making and planning processes inside a tailorable web-based platform. It links requirements to market segmentation, competitor analysis, release planning and other processes in product life cycle management. Gatherspace is a free requirements management and use case development tool that offers multi-user and team functionality. The system is an online solution with different user-tiered packages. There are a variety of reports from basic functionality reports to use case models. 1)

Gatherspace is totally online, no software to download;

Designed and coded by analysts and project managers who full understand the process of gathering requirements;

With an intuitive GUI, Gatherspace also provides a todolist of “what’s next” to create in addition to defining analyst-based terms.

GMARC from Computer System Architects GMARC was one of the earliest RE methods (conceived 1982) and has been continuously developed ever since. Its development was sponsored by the UK’s DTI in 1990 together with the CAA, the MoD, NERC, City University and Kings College London. GMARC is claimed to be unique in its ability to reduce project/programme risk. Brian Hunt of CSA writes: GMARC was initially developed to be able to accumulate multi-layer generic requirements knowledge for subsequent re-use, via automated elicitation, in any application domain. The latest version is able to use such knowledge to progressively improve its ability to understand the semantics of, and capture new requirements in, each domain. To aid the process of understanding an application, GMARC provides a suite of powerful requirements animation facilities. These are able to be used to verify and explore the functional aspects of any specification. In 54

order to take subjectivity out of the process (a universal problem!), GMARC employs a multitude of objective quality metrics to guide requirements development activity.

iRise from iRise.com is a tool for previewing or prototyping a software application before doing any coding. In the process, the requirements are “completely and unambiguously fleshed out - including application and page flows, user interfaces, business logic, data structures and other requirements.” IRqA from TCP Sistemas e Ingeniería IRqA is a Requirements Engineering (RE) tool specifically designed to support the complete RE process. In IRqA the complete specification cycle including requirements capture, analysis, system specification, validation and requirement organisation is supported via standard models. Antonio Monzón, then of TCP Sistemas e Ingeniería: “with IrqA, we cover the full requirements specification cycle, not only RM and capture but also analysis, specification — features related to the construction of a specification; we have graphical, visual features like State Machines, Use Cases, graphical structuring of specifications — functional, non-functional, test cases, diagrams of review processes, information models, link matrices." Jalsoft from Jalsoft is a web-based RM tool. The tool contains a database (DB2, Oracle or SQL/Server) and an ordinary web server at the server end; the thin client is simply a web browser, so installation is trivial and learning is said to be a matter of minutes. The tool integrates with Word, MS Office and MS Project; there is an XMI interface to other tools, and CSV file import and export. The tool can therefore be used ‘from anywhere in the world’. RM functions like trace ability, history, base lining and reporting are provided. Leap SE from Leap Systems Leap SE is a requirements engineering CASE tool that produces object-oriented models directly from a system requirements repository or specification (SRS). A 30-day trial version is available. Brian Smith of Leap Systems writes: “By translating English into logical models for software development, Leap SE achieves RAD from the source, dramatically shortening the systems analysis phase for software projects.” MKS Requirements 2005 from MKS MKS Requirements 2005 is a ‘right-weight’ RM tool built as an integral part of a Configuration Management system (MKS Integrity Manager, via its process/workflow engine). It integrates with Microsoft Word, organizes requirements hierarchically, provides history, metrics, traceability to source code, suspect links, etc. Low cost of ownership is claimed. The vendor claims: “the clear connection between requirements, development activity and development artifacts delivers an unprecedented level of audit-ability, something every IT organisation must demonstrate for Sarbanes-Oxley compliance.” MockupScreens from Igor Jese MockupScreens is a rapid User Interface prototyping tool. You create screen mockups and organise them into scenarios, complete with buttons, fields, lists etc. Free evaluation copy from website. Objectiver from Cediti Cediti is a spin-off from the University of Louvain, Belgium (UCL), and the tool is based on the KAOS method of analysing goals devised by Prof. Axel van Lamsweerde. The tool thus has a solid foundation (capable of formal proof) for modeling goals, requirements, agents, entities, events relationships, actions, etc., with all the relationships between them (cause-effect, conflict, instance-of, goal refinement, etc.), supported by editable diagrams. The vendor claims that key advantages of Objective are: • •

it enables analysts to elicit and specify requirements in a systematic way, it produces well structured, self-contained, motivated, easily understandable, standard requirements documents, 55

Management Systems

• •

it provides highly effective way to communicate about the requirements, it ensures trace ability from requirements to goals and from high-level, coarsegrained behavioural specifications to requirements.

OPEN Process Framework (OPF) from Firesmith Consulting: This remarkable toolkit contains a repository of reusable process components for building project-specific processes for software-intensive systems — complete, hook, line and sinker. There are numerous reusable process components including work products (from requirements, diagrams, models, documents to components), work units (activities, tasks, and techniques), producers (roles, teams, organisations), enterprises (projects, programs, enterprises), and stages (development cycles, phases, milestones). Requirements are supported in detail including document content and format standards, templates, inspection checklists, and guidelines. Rally from Rally Software Development This is a tool intended specially to support Agile software development. RDT from IgaTech Systems RDT is a relatively simple tool from an Australian company. It is based on Microsoft Office, but with numerous custom forms (pop-up windows) for entering settings, attributes, etc., and for displaying results. Thought has been given to getting requirements in from ordinary Word documents, and to producing documents as reports by filtering, selecting attributes, and formatting. This seems to make it intermediate between ‘light’ products like Require IT and Requisite Pro, and ‘full’ products like DOORS and RDD. ‘Capture’ is interpreted simply as ‘import and extraction’. The tool wisely encourages users to record design rationale. Gordon Brimble of IgaTech: RDT provides highly capable document handling for parsing input documents and creating output documents, capture of derivations that link derived requirements to record the logic behind requirement flow down and integration with requirements modeling tools. Reconcile from Compuware This is one of a suite of tools focused on quality assurance and change management. Reqtify from TNI-Valiosys This is one of a suite of tools designed to assist the development of mission- and safety-critical software (in C, C++, Ada) for aerospace, defence, and industry. Rectify is a low-cost traceability and impact analysis tool. It is said to take just 1/2 a day to learn. It interfaces to Word and other word processing tools, the other TNIValiosys modeling tools, Simulink, etc. It has been applied on Airbus A380 computer projects (alongside RTM) with thousands of requirements and links. Interestingly, the tool is document-centric: requirements are tagged by the user in the source documents; the tool searches for these tags each time a source document is saved, and makes a snapshot of the requirements so discovered. Lionel BURGAUD of TNI-Valiosys: For project and quality engineers who need to track requirements across the development cycle, Reqtify (tool) is a low-cost, highly customizable and easy to use tool that manages requirements traceabitity, impact analysis, filtering and versioning. Unlike other database tools, Reqtify (tool) processes information directly extracted from the source files (text processing, Excel, PDF, UML, analysis & modelling, code, etc.) without requiring any modifications, and therefore can be very quickly deployed even on projects already started.

RequireIT from Telelogic DOORSrequireIT is Doors’ little sister. It is effectively a rival to Requisite Pro, as it is a Microsoft Word tool in which users edit and mark up a Word document with hidden fields that function as custom attributes (owner, status, date, etc.) and as traceability links between requirements. RequireIt is simple to use and does not involve the complexity of reliance on a database as well as on Word, so it

is easier-to-use tool than its rivals, and may be more reliable. It is implemented entirely separately from Doors (it uses Word macros not compiled code) and is intended for use on small projects.

Management Functions and Business Processes

Requisite Pro from IBM Rational Requisite Pro aims especially at managing change in requirements, with traceability for software and test specifications. It is closely linked to Microsoft Word, and Rational is a Microsoft Development Partner. The tool permits the use of Oracle on Unix or Windows as the back-end database, and also supports SQL server on Windows. Rational in 2003 merged with IBM which might mean many things, such as a greater focus on research and consultancy, perhaps. Jim Heumann of Rational (former owners of RequisitePro): Rational is about tools but also about services, lots of teams locally that serve people, best practices and thought leadership, and of course our goal is to help people write better software — in a nutshell. RETH, a freeware prototype owned by Siemens, created by Dr. Hermann Kaindl RETH (Requirements Engineering Through Hypertext) is a simple RM tool that demonstrates some powerful aspects of RE. It constructs a set of goals, scenarios, and requirements, each fully-documented with built-in and custom attributes, and interconnected with hyperlinks. Models can be exported to documents and to HTML. Rhapsody from I-Logix Rhapsody is an Object-Oriented Analysis and Design tool for embedded software. The emphasis is rather on design, with analysis using UML to describe objects for subsequent detailed design and code generation. ScenarioPlus ScenarioPlus for Use Cases is a set of free add-on tools for use with Doors. It installs as a menu on the Doors menu bar, and provides for editing and analysing a set of UML-style use cases. Metrics and checklists are provided. There is a strong emphasis on requirements elicitation with easily-understood graphics, generated automatically. The toolset is closely integrated with Doors allowing for complete flexibility in filtering, traceability and reporting. The site also offers a suite of Microsoft Office templates for scenario-based requirements engineering; tools for editing a range of software engineering diagrams, and tools for functions such as filtering and constructing Doors templates. Ian Alexander writes: my aim with Scenario Plus is to improve the engineering of systems (not just software) by encouraging the use of state-of-the-art techniques for requirements elicitation, specification, and validation, including means such as scenarios, graphics, metrics, and templates. Free Prototype Educational Tools for Systems and Software Engineering from SEEC The Systems Engineering & Evaluation Centre at the University of South Australia (UniSA) offers a suite of free tools that “can be used in the classroom and in the workplace”. The tools include the fancifully-named TIGER, ACE, ET, CARP and RAT (ahem. I recall the immortal line from another project back in 1991 “RAT tool is mouse-driven”). These stand for: Tool to InGest and Elucidate Requirements (TIGER), i.e., free text extraction with keywords Acceptance Criteria Elucidator (ACE), i.e., editing the criteria in a database Requirement Enhancing documentation Tool (ET), i.e., attribute editing Comparison Analysis of Requirements Priority (CARP), i.e., prioritization Risk documentation and profiling Tool (RAT), i.e., risk attribute editing. It can be seen that these form a single basic RM environment. They have “a similar user interface”. 57

Management Systems

Serena RTM from Serena is an RM tool providing Word and Web Browser interfaces, discussion threads and change requests, traceability analysis and change management. Any life-cycle method can be supported. The data reside in an Oracle database. The tool forms part of a suite including TeamTrack, a process management tool; ChangeMan, a change management tool; Serena Professional, a configuration management tool; and Collage, a web content management tool. SpeeDEV from SpeeDEV This product takes the approach that requirements in a distributed project need to be developed on the Web. It is claimed to be suitable for hardware as well as software, and covers requirements gathering, “scrubbing”, approving, prioritizing, assigning to version releases, task management, testing, bug tracking and other functions. This sounds as if the toolkit will suit some kinds of project very well, but might prove restrictive if the way the tasks are supported isn’t what your project wants. The Web is clearly the way more tools will go, so expect hot competition in this area. Irene From of SpeeDEV: SpeeDEV operates in a completely Web-based environment to promote the free exchange of information and project team participation. SpeeDEV's solution is the only commercial browser-based solution for local or remote software development collaboration, available as enterprise software. Statestep from Statestep is a free specification tool based on a state model. The user interface allows required behaviour to be defined in decision tables. The tool helps to check systematically that all unusual cases are considered. The resulting model is a finite state machine, which can be checked automatically for completeness and consistency, e.g., that no undesirable state is reachable. The tool has been used commercially to specify consumer electronic systems. Michael Breen writes: “As a relatively specialised tool based on creating a model of behaviour, it’s a bit different to most of the tools in your list... Anyway, one sentence could be: “Among other things, Statestep features a unique colour-based interface which makes it feasible to deal systematically with (for example) millions of possibilities — and so to find obscure problem cases otherwise likely to be overlooked in a specification.” Steeltrace (formerly Catalyze) from Steeltrace takes a structured view of requirements, breaking them into Functional (in the form of a Use Case-like storyboard structure of main flow, alternative flows etc.) and non-functional requirements (qualities and constraints). These map seamlessly to functional test cases, UML activity diagrams, requirements based milestones in project plans etc. Ease of use is emphasised. “SteelTrace lets everyone work together easily to define, communicate and understand project requirements so that business, development, and test deliver quality software faster. Reduce over-runs, re-work and time to delivery. Maximize project quality and ROI.” -- Tadhg O’Brien Teamcenter from UGS includes a requirements tool (formerly Slate): “Industrial Strength Groupware for managing requirements, architecting systems, and accelerating product development”. Tools cover design and testing as well as requirements. The examples on the website include radar and aircraft carrier, so there is a perceptible military-industrial orientation. The tool provides for conventional boxand-arrow diagrams, but also allows document and object hierarchies, and arbitrary traceability linking. An interesting feature is a budget which provides a recursively added hierarchical spreadsheet for each attribute (‘technical allocatable’ in Slate jargon) which is to be budgeted. Slate is apparently genuinely object-oriented and as such should suit large industrial projects that want to use OO analysis and design.

Some systems engineers see Slate as a tool that mainly supports the life-cycle after the requirements phases. It provides limited support for requirements capture.

Management Functions and Business Processes

Harold Knight of SDRC (an earlier owner of Slate): Slate is fundamentally different in Systems Engineering because we manage all components of the design in true ObjectOriented fashion — not documents or paper but information, so we are a system design tool — system engineers can design and view systems from any perspective. Team-Trace from WA Systems is a requirements management tool released in 2002. Ben Sutton of WA Systems: We believe that Team-TRACE is a breakthrough in costeffective requirements management. It offers all of the relevant features found in other tools at a fraction of the cost. Behind an intuitive interface lies an impressive platform that enables you to capture, analyse, evaluate and trace complex requirements. Tiger Pro is one of the free tools. Truereq from Truereq Inc. Truereq is a web-based requirements management tool. There is an open (XML) data interchange format, and the API permits custom integration and scripting. Currently (Feb 2004) Truereq offer a free single-user license. Todd Berger of Truereq writes: Using Truereq, you can manage your product development process in a centralised workspace shared by all your team members. Truereq’s integrated toolkit helps you focus on making better products, more quickly, efficiently, and at a dramatically reduced cost. Vital-Link from Compliance Automation Ivy Hooks’ company produces a database-centred requirements management tool that seems to be well liked. The Volere Template from The Atlantic Systems Guild The Volere Template is a comprehensive list of all the components that the Robertsons recommend should go into a requirements specification. It is closely associated with the Volere method described in their book, but contains many useful suggestions that could enhance any requirements method. The template can be used with any general RE tool or simply with word-processed documents. WIBNI from Project Toolbox (Wouldn’t It Be Nice If ...?) is a very low cost RM tool based on Microsoft Access, (like Requisite Pro and DoorsRequireIT). It records priority, status, type, and other attributes, documents links between requirements, keeps an audit trail, exports to Word, and enables sorting and filtering like much heavier tools. Interestingly it also supports event-driven and use-case analysis. There is a free evaluation version. John Richards of Project Toolbox writes: “I’ve been managing projects for many years and could not find a requirements database I wanted to use at a price I could justify. I knew what I wanted though, so in the end I developed it.” XTie-RT from Teledyne Brown Engineering (TBE) TBE released XTie-RT commercially in July 1996. The tool was initially developed for in-house use to assist with proposal development, regulation compliance on environmental programs and large complex systems for the US Army and NASA. It encourages users to document the reasons for decisions. Users are equally divided between Government contractors and Commercial industry, and between hardware and software. The tool is claimed to be simple to learn, robust and full featured. TBE consider Doors their primary competitor.

INTRODUCTION

79 80 82

In the previous unit, we discussed the diverse requirements which the management has to meet for achieving the goals of the organisation. In this unit, we will carry this discussion further to discuss what assistance information systems can provide to the manager for efficiently discharging his responsibilities. A manager has to carry out the role of a functional expert, carry out decisions, plan and co-ordinate for which he/she has to perform the role of a communicator and control all the activities under his/her responsibility. Depending upon his/her position/level in the hierarchy a manager has to carry out strategic, managerial or operational responsibilities. We will discuss how by providing an appropriate system a manager can be helped.

3.1 OBJECTIVES After going through this unit, you should be able to: • • •

understand basics of management systems and their types; describe the management systems for the roles a manager has to fulfil, and design the Information systems required at various levels of management.

3.2

MANAGEMENT SYSTEM TYPES

Management systems are the formal, observable ways in which an organisation administers its operations. We can also say a management system provides the framework of processes and procedures used to ensure that an organisation can fulfil all tasks required to achieve its objectives. For instance, an environmental management system enables organisations to improve their environmental performance through a process of continuous improvement. An oversimplification is “Plan, Do, Check, Act.” A more complete system would include accountability (an assignment of personal responsibility) and a schedule of activities to be completed, as well as auditing tools to implement corrective actions in addition to scheduled activities, creating an upward spiral of continuous improvement. Because there are different interests, specialities, and levels in an organisation, there are different management systems types. No single system can provide all the information an organisation needs. More and more of these management systems are being covered under computerization; some of the management systems that have been computerised in various organisations are given below: 64

Administrative management system

Human resources management system Accounting management system Customer relationship management system Knowledge management system Logistics management system Marketing management system Operations management system Project management system Process management system Personal management system Product management system Quality management system Resource management system Risk management system Supply chain management system Time management system.

Management Systems

Some of these Management Systems operate only at a specific management level, whereas, some operate across management levels. Some operate within one management function, whereas some operate across management functions.

3.3 MANAGEMENT SYSTEM REQUIREMENTS Efficient and effective operation of a business requires a management system, which can support business processes and operations, decision-making, and competitive strategies. In the unit 2.2, we discussed using the functional approach and tried to answer the question, what do managers do? We observed that the managers plan, organise, coordinate, direct and control. Now let us look at what functions management systems do? or why management systems are required? In addition to the broad categories of management functions, managers at different levels of the hierarchy fill different managerial roles. Let us look at these roles: The functional support role Business processes and operations support function are the most basic. They involve collecting, recording, storing, and basic processing of data. Information systems support business processes and operations by: • Recording and storing accounting records including sales data, purchase data, investment data, and payroll data, • Processing such records into financial statements such as income statements, balance sheets, ledgers, and management reports, etc. • Recording and storing inventory data, work in process data, equipment repair and maintenance data, supply chain data, and other production/operations records, • Processing these operations records into production schedules, production controllers, inventory systems, and production monitoring systems, • Recording and storing such human resource records as personnel data, salary data, and employment histories, • Processing these human resources records into employee expense reports, and performance based reports, • Recording and storing market data, customer profiles, customer purchase histories, marketing research data, advertising data, and other marketing records, • Processing these marketing records into advertising elasticity reports, marketing plans, and sales activity reports, • Recording and storing business intelligence data, competitor analysis data, industry data, corporate objectives, and other strategic management records, and

• Management Systems

Processing these strategic management records into industry trends reports, market share reports, mission statements, and portfolio models. The bottom line is that the information systems use all of the above to implement, control, and monitor plans, strategies, tactics, new products, new business models or new business ventures. The decision role Decisional roles require managers to plan strategies and utilise resources. There are four specific roles that are decisional. The entrepreneur role requires the manager to assign resources to develop innovative goods and services, or to expand a business. Most of these roles will be held by top-level managers, although middle managers may be given some power to make such decisions. The disturbance handler corrects unanticipated problems facing the organisation from the internal or external environment. Managers at all levels may take this role. For example, first-line managers may correct a problem halting the assembly line or a middle level manager may attempt to address the aftermath of a fire in the store. Top managers are more likely to deal with major crises, such as requiring a recall of defective products. The third decisional role, that of resource allocator, involves determining which work units will get which resources. Top managers are likely to make large, overall budget decisions, while middle managers may make more specific allocations. In some organisations, supervisory managers are responsible to determine allocation of salary raises to employees. Finally, the negotiator works with others, such as suppliers, distributors, or labour unions, to reach agreements regarding products and services. First-level managers may negotiate with employees on issues of salary increases or overtime hours, or they may work with other supervisory managers when needed resources must be shared. Middle managers also negotiate with other managers and are likely to work to secure preferred prices from suppliers and distributors. Top managers negotiate on larger issues, such as labor contracts, or even on mergers and acquisitions of other companies. The interpersonal role Interpersonal roles require managers to direct and supervise employees and the organisation. The figurehead is typically a top of middle manager. This manager may communicate future organisational goals or ethical guidelines to employees at company meetings. A leader acts as an example for other employees to follow, gives commands and directions to subordinates, makes decisions, and mobilises employee support. Managers must be leaders at all levels of the organisation; often lower-level managers look to top management for this leadership example. In the role of liaison, a manager must coordinate the work of others in different work units, establish alliances between others, and work to share resources. This role is particularly critical for middle managers, who must often compete with other managers for important resources, yet must maintain successful working relationships with them for long time periods. The communication role Information systems can support a company’s competitive positioning. Here are three levels of analysis:

The supports for help in piloting the chain of internal value. They are the most recent and the most pragmatic systems within the reach of the manager. They are the solutions to reductions of costs and management of performance. They are typically named “Business Workflow Analysis” (BWA) or “Business Management Systems (BMS)”. They ensure control over piloting the set functions of a company. The real-time mastery in the costs of dysfunctions, cause distances from accounts, evaluation and accounting that are presented in the evaluation and qualitative reports.

All successful companies have one (or two) business functions that they do better than the competition. These are called core competencies. If a company’s core competency gives it a long-term advantage in the marketplace, it is referred to as a sustainable competitive advantage. For a core competency to

become a sustainable competitive advantage it must be difficult to mimic, unique, sustainable, superior to the competition, and applicable to multiple situations. For a small or medium business a nice alternative is a MSP or a Managed Service Provider such as Virtual IT Solution, This is a cost effective solution compared to paying for IT staff or local technicians. Other examples of company characteristics that could constitute a sustainable competitive advantage include: superior product quality, extensive distribution contracts, accumulated brand equity and positive company reputation, low cost production techniques, patents and copyrights, government protected monopoly, and superior employees and management team. The list of potential sustainable competitive advantage characteristics is very long. However, some experts hold that in today's changing and competitive world, no advantage can be sustained in the long run. They argue that the only truly sustainable competitive advantage is to build an organisation that is so alert and so agile that it will always be able to find an advantage, no matter what changes occur. 3)

Management Systems

Information systems often support and occasionally constitute these competitive advantages. The rapid change has made access to timely and current information critical in a competitive environment. Information systems, like business environmental scanning systems, support almost all sustainable competitive advantages. Occasionally, the information system itself is the competitive advantage. One example is Wal-Mart. They used an extranet to integrate their whole supply chain. This use of information systems gave Sam Walton a competitive advantage for two decades. Another example is Dell Computer. They used the Internet to market custom assembled PCs. Michael Dell is still benefiting from this low-cost promotion and distribution technique. Other examples are eBay, Amazon.com, Federal Express, and Business Workflow Analysis.

The performance monitoring role MIS are not just statistics and data analysis. They have to be used as an MBO (Management by objectives) tool. They help: • • •

To establish relevant and measurable objectives To monitor results and performances (reach ratios) To send alerts, in some cases daily, to managers at each level of the organisation, on all deviations between results and pre-established objectives and budgets.

Figure 1: Types of systems

For each functional area in the organisation, four levels of organisational hierarchy can be identified: the operational level, knowledge level, management level and strategic level. Each of these levels is served by different types of information systems as shown above in Figure 1. Organisations have transaction processing systems (TPS) at the operational level; knowledge work systems (KWS) and office automation systems (OAS) at the knowledge level; management information systems (MIS) and decision-support systems (DSS) at the management level; and executive support systems (ESS) at the strategic level. Each of the major functional areas of sales and marketing, manufacturing, finance, accounting, and human resources, in turn is served by specialised Systems at each level. The typical features of these six types of information systems are summarized in 68

Table 1. It should be noted that each of the different kinds of systems might have components that are used by organisational levels and groups other than their main constituencies; for example; a middle manager may need to extract data from a TPS.

3.4.1 Transaction Processing Systems (TPS) TPS record daily routine transactions such as sales orders from customers, or bank deposits and withdrawals. TPS are vital for the organisation, as they gather all the input necessary for other types of systems. Think about how one could generate a monthly sales report for middle management or critical marketing information to senior managers without TPS. TPS provide the basic input to the companyâ&#x20AC;&#x2122;s database. A failure in the TPS often means disaster for the organisation. Imagine what happens when the reservation system at Air India fails: all operations stop, no transactions can be carried out until the system is up again. Long queues form in front of ATMs and tellers when a bankâ&#x20AC;&#x2122;s TPS crashes.

Management Systems

Figure 2: Payroll System (TPS) â&#x20AC;&#x201D; a Symbolic Representation

At the operational level, tasks, resources, and goals are predefined and highly structured. The decision to grant credit to a customer, for instance, is made by a lower-level supervisor according to predefined criteria. All that must be determined is whether the customer meets the criteria. Payroll processing is a typical TPS by HR or Finance and Accounts department and is required by almost all firms. A payroll system keeps track of the money paid to employees. The master file is composed of several pieces of information (such as a name, address, or employee number) called data elements. Data are keyed into the system, updating the data elements. The elements on the master file are combined in different ways to create reports of interest to management and Tax / PF Authorities and to send paychecks to employees. These TPS can generate other report combinations of existing data elements. A typical pay processing is shown in Figure 2 above.

Typical TPS applications for five functions that is for sales/ marketing, manufacturing / production, finance/ accounting, human resources are shown in Table 2:

There are five functional categories of TPS: sales/marketing, manufacturing/production, finance/accounting, human resources, and other types of systems specific to a particular industry. Within each of these major functions are sub-functions. For each of these sub-functions (e.g., sales management) there is a major application system.

Managers need TPS to monitor the status of internal operations and the firm’s relations with the external environment. TPS are also major producers of information for the other types of systems. Failure of a TPS will lead to the failure of IS of an organisation. (For example, the payroll system illustrated in Figure 2, along with other accounting TPS, supplies data to the company’s general ledger system, which is responsible for maintaining records of the firm’s income and expenses and for producing reports such as income statements and balance sheets). Features of Transaction Processing Systems a) Rapid Response Fast performance with a rapid response time is critical. Businesses cannot afford to have customers waiting for a TPS to respond, the turnaround time from the input of the transaction to the production for the output must be a few seconds or less. b) Reliability Many organisations rely heavily on their TPS; a breakdown will disrupt operations or even stop the business. For a TPS to be effective its failure rate must be very low. If a TPS does fail, then quick and accurate recovery must be possible. This makes well– designed backup and recovery procedures essential. c) Inflexibility A TPS wants every transaction to be processed in the same way regardless of the user, the customer or the time of day. If a TPS were flexible, there would be too many opportunities for non-standard operations, for example, a commercial airline needs to consistently accept airline reservations from a range of travel agents, accepting different transactions data from different travel agents would be a problem. (d) Controlled processing The processing in a TPS must support an organisation’s operations. For example if an organisation allocates roles and responsibilities to particular employees, then the TPS should enforce and maintain this requirement. e) ACID Test Properties 71

i) Management Systems

Atomicity: A transactionâ&#x20AC;&#x2122;s changes to the state are atomic: either all happen or none happen. These changes include database changes, messages, and actions on transducers.

ii) Consistency: A transaction is a correct transformation of the state. The actions taken as a group do not violate any of the integrity constraints associated with the state. This requires that the transaction be a correct program. iii) Isolation: Even though transactions execute concurrently, it appears to each transaction T, that others executed either before T or after T, but not both. iv) Durability: Once a transaction completes successfully (commits), its changes to the state survive failures.

3.4.2 Knowledge Work Systems (KWS) Knowledge Work Systems (KWS) support highly skilled knowledge workers in the creation and integration of new knowledge into the company. Computer Aided Design (CAD) systems used by product designers not only allow them to easily make modifications without having to redraw the entire object (just like word processors for documents), but also enable them to test the product without having to build physical prototypes. Three dimensional graphical simulation systems like GRASP (Graphical Robotics Applications Simulation Package) are used by British Aerospace and Rolls Royce for evaluating and programming industrial robots. Architects use CAD software to create, modify, evaluate and test their designs; such systems can generate photorealistic pictures, simulating the lighting in rooms at different times of the day, perform calculations, for instance on the amount of paint required. Surgeons use sophisticated CAD systems to design operations. Financial institutions are using knowledge work systems to support trading and portfolio management with powerful high-end PCs. These allow managers to get instantaneous analysed results on huge amounts of financial data and provide access to external databases. Knowledge work systems (KWS) and office systems serve the information needs at the knowledge level of the organisation. Knowledge work systems aid knowledge workers, whereas office automation systems primarily aid data workers (although they are also used extensively by knowledge workers). In general, knowledge workers are people who hold formal university degrees and who are often members of a recognized profession, such as engineers, doctors, lawyers, and scientists. Their jobs consist primarily of creating new information and knowledge. Knowledge work systems (KWS), such as scientific or engineering design workstations, promote the creation of new knowledge and ensure that new knowledge and technical expertise are properly integrated into the business. Data workers typically have less formal, advanced educational degrees and tend to process rather than create information. They consist primarily of secretaries, accountants, filing clerks, or managers whose jobs are principally to use, manipulate, or disseminate information. Office systems are information technology applications designed to increase data workersâ&#x20AC;&#x2122; productivity by supporting the coordinating and communicating activities of the typical office. Office systems coordinate diverse information workers, geographic units, and functional areas: The systems communicate with customers, suppliers, and other organisations outside the firm and serve as a clearinghouse for information and knowledge flows.

3.4.3 Office Automation System (OAS) 72

Office Systems or Office Automation Systems (OAS) support general office work for handling and managing documents and facilitating communication. Text and image

processing systems evolved from word processors to desktop publishing, enabling the creation of professional documents with graphics and special layout features. Spreadsheets, presentation packages like PowerPoint, personal database systems and note-taking systems (appointment book, notepad, card file) are part of OAS.

Management Systems

In addition OAS include communication systems for transmitting messages and documents (e-mail) and teleconferencing capabilities.

3.4.4 Management Information Systems Management Information Systems (MIS) generate information for monitoring performance (e.g., productivity information) and maintaining coordination (e.g., between purchasing and accounts payable). MIS extract process and summarise data from the TPS and provide periodic (weekly, monthly, quarterly) reports to managers. Today MIS are becoming more flexible by providing access to information whenever needed (rather than prespecified reports on a periodic basis). Users can often generate more customized reports by selecting subsets of data (such as listing the products with 2% increase in sales over the past month), using different sorting options (by sales region, by salesperson, by highest volume of sales) and different display choices (graphical, tabular). Management information systems can be defined as the study of information systems in business and management. The term management information systems (MIS) also designates a specific category of information systems serving management-level functions. Management information systems (MIS) serve the management level of the organisation, providing managers with reports and, in some cases, with on-line access to the organisationâ&#x20AC;&#x2122;s current performance and historical records. Typically, they are oriented almost exclusively to internal, not environmental or external, events. MIS primarily serve the functions of planning, controlling, and decision making at the management level. Generally, they depend on underlying transaction processing systems for their data.

MIS summarize and report on the companyâ&#x20AC;&#x2122;s basic operations. The basic transaction data from TPS are compressed and are usually presented in long reports that are produced on a regular schedule. Figure 3 shows how a typical MIS transforms transaction-level data from inventory, production, and accounting into MIS files that are used to provide managers with reports. Table 3 shows a sample report from this system.

Another example of MIS is available from the sales TPS wherein transaction data (name of salesperson, customer name and address, name and quantity of item sold, line sales amount, total sales amount, form of payment) are stored on every sale made. The MIS then generates reports (the frequency of the report being specified by users) such as: • • •

total sales for each item total sales for region sales for each salesperson.

MIS reports can be classified by content or time. In terms of content, reports may be comprehensive (listing each sales transaction over a specified period in a given sales region), summary (showing the total sales of each item sold in a given region) or exception reports (listing items that have shown a drop in sales by over 20% in a given region since the last period). In terms of time, MIS produce historical reports (comparing past sales information with the present); status reports (only showing current sales); and predictive reports (forecasts of next months sales). MIS are not just statistics and data analysis, but also assessment of human capabilities. They have to be used as an MBO (Management by objectives) tool. They help: 74

â&#x20AC;˘ â&#x20AC;˘

to monitor results and performances (reach ratios) to send alerts, in some cases daily, to managers at each level of the organisation, on all deviations between results and pre-established objectives and budgets.

Management Systems

3.4.5 Decision-Support Systems Decision-support systems (DSS) also serve the management level of the organisation. DSS help managers make decisions that are unique, rapidly changing, and not easily specified in advance. They address problems where the procedure for arriving at a solution may not be fully predefined in advance. Although DSS use internal information from TPS and MIS, they often bring in information from external sources, such as current stock prices or product prices of competitors. Clearly, by design, DSS have more analytical power than other systems. They are built explicitly with a variety of models to analyse data, or they condense large amounts of data into a form where they can be analysed by decision makers. DSS are designed so that users can work with them directly; these systems explicitly include user-friendly software. DSS are interactive; the user can change assumptions, ask new questions, and include new data. As mentioned above, there are theoretical possibilities of building such systems in any knowledge domain. One example is the Clinical decision support system for medical diagnosis. Other examples include a bank loan officer verifying the credit of a loan applicant or an engineering firm that has bids on several projects and wants to know if they can be competitive with their costs. A specific example concerns the Canadian National Railway system, which tests its equipment on a regular basis using a decision support system. A problem faced by any railroad is worn-out or defective rails, which can result in hundreds of derailments per year. Under a DSS, CN managed to decrease the incidence of derailments at the same time other companies were experiencing an increase. DSS has many applications that have already been spoken about. However, it can be used in any field where an organisation finds its necessity. Additionally, a DSS can be designed to help make decisions on the stock market, or deciding which area or segment to market a product toward. A very useful, small, but powerful DSS is the voyage-estimating system of a company that exists primarily to carry bulk cargoes of coal, oil, ores, and finished products for another company with which it has a long term contract. The firm owns some vessels, charters others, and bids for shipping contracts in the open market to carry general cargo. A voyage-estimating system calculates financial and technical voyage details. Financial calculations include ship/time costs (fuel, labour, capital), freight rates for various types of cargo, and port expenses. Technical details include a myriad of factors such as ship cargo capacity, speed, port distances, fuel and water consumption, and loading patterns (location of cargo for different ports). The system can answer questions such as the following: Given a customer delivery schedule and an offered freight rate, which vessel should be assigned at what rate to maximize profits? What is the optimum speed at which a particular vessel can optimize its profit and still meet its delivery schedule? What is the optimal loading pattern for a ship bound for Mumbai from London? Figure 4 illustrates the DSS built for this company. The system operates on a powerful desktop personal computer, providing a system of menus that makes it easy for users to enter data or obtain information

3.4.6 Executive Support Systems (ESS) Senior managers use executive support systems (ESS) to make decisions. ESS serves the strategic level of the organisation. They address non-routine decisions requiring judgment, evaluation, and insight because there is no agreed-on procedure for arriving at a solution. ESS creates a generalised computing and communications environment rather than providing any fixed application or specific capability. ESS is designed to incorporate data about external events such as new tax laws or competitors, but they also draw summarized information from internal MIS and DSS. They filter, compress, and track critical data, emphasizing the reduction of time and effort required to obtain information useful to executives. ESS employ the most advanced graphics software and can deliver graphs and data from many sources immediately to a senior executiveâ&#x20AC;&#x2122;s office or to a boardroom. Unlike the other types of information systems, ESS is not designed primarily to solve specific problems. Instead, ESS provides a generalised computing and telecommunications capacity that can be applied to a changing array of problems. Whereas many DSS are designed to be highly analytical, ESS tends to make less use of analytical models.

Questions ESS assists in answering include the following: In what business should we be? What are the competitors doing? What new acquisitions would protect us from cyclical business swings? Which units should we sell to raise cash for acquisitions? Figure 5 illustrates a model of an ESS. It consists of workstations with menus, interactive graphics, and communications capabilities that can access historical and competitive data from internal corporate systems and external databases such as Dow Jones News/Retrieval or the Gallup Poll. Because ESS are designed to be used by senior managers who often have little, if any, direct contact or experience with computer-based information systems, they incorporate easy-to-use graphic interfaces. Relationship of Systems to one Another Different types of systems exist in organisations. Not all organisations have all of the types of systems described in this unit. Many organisations may not have knowledge work systems, executive support systems or decision support systems. But today most organisations make use of office automation systems and have a portfolio of information system applications based on TPS and MIS (marketing systems, manufacturing systems, human resource systems). Some organisations have hybrid information systems that contain some of the characteristics of different types of systems. The field of information systems is moving so quickly that the features of one particular type of system are integrated to other types (e.g., MIS having many of the features of ESS). System characteristics evolve and new types of systems emerge. Yet the classification of information systems into these different types is useful because each type of system has certain features that are relevant in particular situations. Figure 6 illustrates how the systems serving different levels in the organisation are related to one another. TPS are typically a major source of data for other systems, whereas ESS is primarily a recipient of data from lower-level systems. The other types of systems may exchange data with each other as well. Data may also be exchanged among systems serving different functional areas. For example, an order captured by a sales system may be transmitted to a manufacturing system as a transaction for producing or delivering the product specified in the order.

Management Systems

It is definitely advantageous to have some measure of integration among these systems so that information can flow easily between different parts of the organisation. But integration costs money, and integrating many different systems is extremely time consuming and complex. Each organisation must weigh its needs for integrating systems against the difficulties of mounting a large-scale systems integration effort.

3.5 SUMMARY With this unit, we complete our discussion on various roles a manger has to play and how information systems can assist him/has in for these roles. In this unit you have also learned that depending upon the position / level in the hierarchy, a manager has to carry out strategic, managerial or operational responsibilities and there are appropriate information systems for these levels. Decision support and strategic support information systems have very large scope for implementation in various organisations. Students therefore, must further study case studies in these areas.

3.6 SOLUTIONS / ANSWERS Check Your Progress 1 i)

Management systems can be defined as formal, observable ways in which an organisation administers its operations. A management system provides the framework of processes and procedures used to ensure that the organisation can fulfill all tasks required to achieve its objectives. Five management systems are listed below: • • • • •

ii)

Change management system Cost management system Crisis management system Facility management system Knowledge management system

The three levels of analysis in which Information systems can support, a company’s competitive positioning are: (a) Internal Business Management Systems, (b) Company’s Core competence, and (c) Competitive environment Information systems. a) Internal Business Management Systems: These systems provide the solutions for reduction of costs and for enhancement of management of performance. Control over piloting the set functions of the company can be carried out, by using these systems. The system output provides evaluation and qualitative reports. b) Company’s Core competence: To ensure that a company’s core competency remains in an advantageous position / sustainable it must be difficult to mimic, unique, sustainable, superior to the competition, and applicable to multiple situations. This advantage could come from superior product quality, extensive distribution contracts, accumulated brand equity and positive company reputation, low cost production techniques, patents and copyrights, government protected monopoly, and superior employees and management team. In today’s changing and competitive world the only truly sustainable competitive advantage is to build an organisation backed by an information system, that is so alert and so agile that it will always be able to find an advantage, no matter what changes occur. c) Competitive environment Information systems: These are the Information systems which provide business environmental scanning, and implementation of business processes to ensure competitive advantages. These systems need to provide access to timely and current information critical in a competitive environment.

4.0 INTRODUCTION In this unit, we will briefly discuss the impact information systems have on business, organisations and individuals. It is a well-realised fact that despite the ever-increasing importance of the information resource, evaluating the actual benefits of using information systems remains problematic. Nevertheless, due to cost and time factors involved in designing and implementing information systems, it is essential to work out cost benefit analysis and total cost of owning the system. We will be discussing these as well as the Empirical studies which have been getting due recognition due to the human angle involved in the information systems implementation. The cultural considerations are the other important factor in information systems implementation which will be discussed here. Decision making, Decision management and Decision support systems constitute one of the areas which has been influenced by the information systems and this topic will also be covered in this unit.

4.1 OBJECTIVES After going through this unit, you should be able to: • • •

understand the business value of an information system and evaluate the business value of information systems; assess impact of culture and human angle requirements for Information system implementation, and appreciate the importance of decision making and use of decision support systems.

4.2 IMPACT OF INFORMATION SYSTEMS Information systems play a role in almost every field of activity in the modern world. They have a major effect on businesses and organisations; they even have a deep impact on our private lives and our culture. Information is an organisational resource and it is a very important production source in information-based industries and services (e.g., banking). The role of business information systems has changed and expanded over the last four decades. In the incipient decade (1950-1960) it started with calculator (bookkeeping; 84

Texas Instruments, HP) and moved on to computers (accounting, payroll; mainframe, mini (IBM)). However, computers could be afforded during that period by only the largest organisations. They were used to record and store bookkeeping data such as journal entries and specialised journals. These were used to generate a limited range of predefined reports, including income statements, balance sheets and sales reports. They were trying to perform a decision-making support role, but they were not up to the task.

Business Values of Information System

By the 1970s “Management Information system and decision support systems” were introduced. They were interactive in the sense that they allowed the user to choose between numerous options and configurations. Not only was the user allowed to customize outputs; they also could configure the programs to their specific needs. There was a cost though. As part of the mainframe leasing agreement, it was possible to have an IBM system developer permanently on site by paying. The main development in the 1980s was the introduction of decentralised computing. Instead of having one large mainframe computer for the entire enterprise, numerous PCs were spread around the organisation. This meant that instead of submitting a job to the computer department for batch processing and waiting for the experts to perform the procedure, each user had has/her own computer that could be customize for their own purposes. People who used these systems and struggled with DOS protocols, BIOS functions, and DOS batch programming during that period, tell their stories with pride. As people became comfortable with their new skills, they discovered all the things their system was capable of. Computers, instead of creating a paperless society, as was expected, produced mountains of paper, most of it of no value. Mounds of reports were generated just because it was possible to do so. This information overload was mitigated somewhat in the 1980s with the introduction of “executive information systems”. They streamlined the process, giving the executive exactly what s/he wanted, and only what was wanted. The 1980s also saw the first commercial application of artificial intelligence techniques in the form of “expert systems”. These programs could give advice within a very limited subject area. The promise of decision making support, first attempted in management information systems back in the 1960s, had step-by-step, come to fruition. The 1990s saw the introduction of the Communicators (e-mail, document management; networks; Microsoft, Cisco) and Strategic information system. These systems used information technology to enable the concepts of business strategy. The role of business information systems had now expanded to include strategic support. The latest step was the commercialization of the Internet, and the growth of intranets and extranets at the turn of the century. All indications are that e-commerce will continue to grow in the coming years. e-commerce, or the use of the internet and the web to conduct business, is typically categorised into business-to-consumer (B2C), business-to-business (B2B), and intraorganisational e-business. Businesses, governments, and nonprofit organisations are increasingly investing in information technology (IT) infrastructures to be able to conduct digitally enabled transactions. Online shoppers, constituting the B2C segment, spent a record Rs.782 billion during the year 2005, according to Research Giant Nielsen / ComScore, representing a 24 percent increase from 2004. While we have witnessed promising growth in the B2C area, there is a tremendous opportunity for generating business value from B2B e-commerce. Moreover, a few traditional businesses, Dell, and Wal-Mart, have been successful in integrating e-commerce into 85

Management Systems

their traditional business models. However, many other companies still struggle with implementing and justifying e-commerce initiatives. Managers primarily worry about falling behind in the implementation of e-commerce initiatives, yet the business value of these initiatives needs justification. The evidence on both the success and failure of such initiatives has been generally anecdotal. This calls for rigorous empirical research examining the payoff realised from e-commerce initiatives. In the twenty first century scenario, another aspect having deep impact is convergence and Integration of Devices – Partners (personal digital assistants, software agents, SMS, Microsoft SOAP, mobile appliances (Figures 1 and 2)

With all these developments the impact of the Information Systems is that at present expectations have shifted towards Now Economy and Integrated Economy.

“Now economy”, a real-time enterprise – organisation that is expected to react instantaneously to changes in its business. To provide “instant gratification” to customers, products and services to be delivered to customers: Anytime (24/7), anywhere (global reach), any form (mass customisation), any price (dynamic pricing depending on real-time supply-demand adjustment). This will require Real-time Monitoring, Reporting and Decision-making.

“Integrated economy” – suppliers, customers, affinity groups, and competitors. We may in due course of time observe all the mega-mergers and alliances and mass marketing being slowly replaced by molecular marketing with specific

customer groups. Businesses have already started moving outside the boundaries of countries. Business Process Outsourcing across countries is already a reality.

Business Values of Information System

Social Global Impact of Information Systems Information technology is not the cause of the changes we are living through. But without new information and communication technologies none of what is changing our lives would be possible. In the 1990s the entire planet is organised around telecommunicated networks of computers at the heart of information systems and communication processes. The entire realm of human activity depends on the power of information, in a sequence of technological innovation that accelerates its pace by month. Genetic engineering, benefiting from this wealth of information processing capacity, is progressing by leaps and bounds, and is enabling us, for the first time, to unveil the secrets of living matter and to manipulate life, with extraordinary potential consequences. Software development is making possible user-friendly computing, so that millions of children, when provided with adequate education, can progress in their knowledge, and in their ability to create wealth and enjoy it wisely, much faster than any previous generation. Internet today used by about 100 million people, and doubling this number every year, is a channel of universal communication where interests and values of all sorts coexist, in a creative cacophony. Certainly, the diffusion of information and communication technology is uneven. Most of Africa is being left in a technological apartheid, and the same could be said of many other regions of the world. Technology per se does not solve social problems. But the availability and use of information and communication technologies are a pre-requisite for economic and social development in our world. They are the functional equivalent of electricity in the industrial era. Econometric studies show the close statistical relationship between diffusion of information technology, productivity and competitiveness for countries, regions, industries and firms. They also show that an adequate level of education in general and of technical education in particular, is essential for the design and productive use of new technologies. But neither the sheer number of scientists and engineers nor the acquisition of advanced technology can be a factor of development by itself without an appropriate organisational environment. The crucial role of information and communication technologies in stimulating development is a two-edged sword. On the one hand, it allows countries to leapfrog stages of economic growth by being able to modernize their production systems and increase their competitiveness faster than in the past. The most critical example is that of the Asian Pacific economies, and particularly the cases of Hong Kong, Taiwan, Singapore, Malaysia and South Korea. This is so despite the current financial crisis, which is unrelated to competitive performance and may be related, in fact, to the attractiveness of booming Asian economies to global capital flows. On the other hand, for those economies that are unable to adapt to the new technological system, their retardation becomes cumulative. Furthermore, the ability to move into the Information Age depends on the capacity of the whole society to be educated, and to be able to assimilate and process complex information. This starts with the education system, from the bottom up, from the primary school to the university. It relates, as well, to the overall process of cultural development, including the level of functional literacy, the content of the media, and the diffusion of information within the population as a whole. In this regard, what is happening is that regions and firms that concentrate the most advanced production and management systems are increasingly attracting talent from around the world, while leaving aside a significant fraction of their own population whose educational level and cultural/technical skills do not fit the requirements of the new production system. A case in point is Silicon Valley the most advanced information technology-producing region in the world, which can only maintain the 87

Management Systems

pace of innovation by recruiting every year thousands of engineers and scientists from India, China, Taiwan, Singapore, Korea, Israel, Russia and Western Europe, to jobs that cannot be filled by Americans because they do not have proper skills. Similarly, in Bangalore, Mumbai, Seoul or Campinas, engineers and scientists concentrate in high-technology hubs, connected to the Silicon Valleys of the world, while a large share of the population in all countries remains in low-end, low-skill jobs, when they are lucky enough to be employed at all. Thus, there is little chance for a country, or region, to develop in the new economy without its incorporation into the technological system of the information age. In sum, information and communication technology is the essential tool for economic development and material well-being in our age; it conditions power, knowledge and creativity; it is, for the time being, unevenly distributed within countries and between countries; and it requires, for the full realisation of its developmental value, an interrelated system of flexible organisations and information-oriented institutions. In a nutshell, cultural and educational development conditions technological development, which conditions economic development, which in turn conditions social development, and this stimulates cultural and educational development once more. This can be a vicious circle of development or a downward spiral of underdevelopment. The direction of the process will not be decided by technology but by society, through its conflictive dynamics. The IT executive must meet these challenges head-on, contending with an environment where businesses are more interconnected and network-enabled than ever before, and information system capabilities will determine the success and failure of core business capabilities. Today’s technology executives must manage risk and ensure that their IT initiatives and investments deliver: •

The high availability and performance required meeting the needs of the global business environment, ensuring that transactions are processed with utmost reliability and security;

•

Collaboration between disparate and geographically dispersed development teams around the globe;

•

The foresight and capability to support emerging technology initiatives such as service-oriented architectures (SOA).

4.3 EMPIRICAL STUDIES While empirical studies in software engineering are beginning to gain recognition in the research community, this sub area is also entering a new level of maturity by beginning to address the human aspects of software development. This added focus has added a new layer of complexity to an already challenging area of research. Along with new research questions, new research methods are needed to study non- technical aspects of software engineering. In many other disciplines, qualitative research methods have been developed and are commonly used to handle the complexity of issues involving human behaviour. While empirical evaluations are a common research method in some areas of Information systems like, Artificial Intelligence (AI), others still neglect this approach. Here we will be discussing advantages, opportunities, and limits of empirical evaluations outlining both the opportunities and the limits of empirical evaluations for IS / AI techniques with the examples of the evaluation of adaptive systems. Using the so called layered evaluation approach, we will demonstrate that empirical evaluations are able to identify errors in IS / AI systems that would otherwise remain undiscovered. 88

1) Advantages: Why Evaluations are Needed Some areas of IS / AI apply empirical methods regularly, e.g., planning and search algorithms are benchmarked in standard domains, and machine learning algorithms are usually tested with real data sets. However, looking at some applied areas such as user modeling, empirical studies are rare, e.g., only a quarter of the articles published in User Modeling and User Adapted Interaction (UMUAI) are reporting significant empirical evaluations. Many of them include a simple evaluation study with small sample sizes and often without any statistical methods.

Business Values of Information System

On the other hand, for an estimation of the effectiveness, efficiency, and the usability of a system that applies IS / AI techniques in real world scenarios, empirical research is absolutely necessary. Especially user modeling techniques which are based on human-computer interaction require empirical evaluations. Otherwise, as we are going to demonstrate, certain types of errors will remain undiscovered. Undoubtedly, verification, formal correctness, and tests are important methods for software engineering; however, we state that empirical evaluation — seen as an important complement — can improve IS / AI techniques considerably. Moreover, the empirical approach is an important way to both, legitimise the efforts spent, and to give evidence to the usefulness of an approach. 2) Opportunities: What we may learn from Empirical Evaluations Empirical methods for IS / AI should answer three basic research questions: •

How will a change in the agent’s structure affect its behaviour given a task and an environment?

•

How will a change in an agent’s task affect its behaviour in a particular environment?

•

How will a change in an agent’s environment affect its basic behaviour on a particular task?

These questions may be answered by a combination of four kinds of empirical studies: exploratory studies that yield causal hypotheses; assessment studies that establish baselines, ranges, and benchmarks; manipulation experiments to test hypotheses about causal influences; and finally observation experiments (or quasi-experiments) that disclose effects of factors on measured variables without random assignment of treatments. These general and goal defining questions have to be specified in terms of each IS/ AI area. As an illustrative example, we outline the opportunities of empirical evaluations for adaptive systems and user modeling. Similar results can be obtained for other IS / AI systems. The evaluation of adaptive systems can be seen as a layered process where each evaluation layer is a prerequisite for the subsequent layers. Three approaches have been proposed that basically just differ in layer granularity. Thus, we will outline four layers of evaluation of adaptive systems here. Figure 3 shows the four layers: During interaction the adaptive system observes the user and registers certain events or behaviour cues. (1) Based on these input data abstract user properties are inferred, (2) Finally the system decides what and how to adapt, (3) presents the adapted interface to the user, (4) Each layer has to be evaluated to guarantee adaptation success.

2.1

Evaluation of Reliability and Validity of Input Data

The first layer evaluates the reliability and the external validity of input data. Unreliable input data would result in mis-adaptations. If input data turns out to be unreliable, further inferences might be distorted or even impossible Layered Evaluation: The Layered Evaluation approach defines several abstract data processing steps within adaptive systems that have to be evaluated in order to guarantee adaptivity success. The evaluation is conducted in layers which mean that a successful evaluation of a previous layer is prerequisite for the subsequent layers, e.g., only if the user properties have been inferred correctly it is possible to evaluate different adaptation decisions, because the adaptation decision relies on the user properties Objectivity, Reliability, Validity: The quality of observed data may be described in terms of three quality measures. Proper observations are independent of the observer (objectivity), are not biased or distorted by the observation method (reliability), and measure exactly the variable that was intended (validity). As adaptive systems observe the user these quality measures are relevant for empirical evaluation. 2.2

Evaluation of Inference

By evaluating the systemâ&#x20AC;&#x2122;s inference it is possible to test the inference mechanism in different environments under real world conditions. Three kinds of studies are used to evaluate the inference. First, exploratory studies can provide empirical grounds for the agentâ&#x20AC;&#x2122;s structure. Second, simulations with hypothetical users can prove that certain combinations of input data are processed as expected. Third, in classical experimental settings it is possible to compare the inferences of the system with the real world. 2.3

Evaluation of Adaptation Decision

Even if a system has inferred some user properties there are usually several adaptation possibilities left. Comparing different adaptation decisions (possibly including nonadaptation) estimates the effects of adaptation and may prove the chosen decision to be the most successful. e.g., on comparing four different adaptation methods in an adaptive learning system. Each method considered the same user properties but adapted the interface in a different way (i.e., with / without adaptive guiding and with / without link annotation). 90

2.4

Evaluation of Interaction

The previous layers may show that the system is consistent and infers correct user properties. However, adaptation might still be unsuccessful because users become confused or dissatisfied. Thus, the human-system interaction has to be evaluated as well. Both, objective and subjective measures are relevant. e.g., users might rate the systemâ&#x20AC;&#x2122;s usability or the solution quality. Examples of objective criteria for interaction quality include frequency of task success and number of required hints.

Business Values of Information System

The examples above emphasize the necessity of empirical evaluations in each of the four layers. It is impossible to detect certain kinds of mis-adaptations that result from biased input data, false inferences, or inadequate adaptation decisions, except for testing the system or parts of the system with real users. Especially usability issues highly depend on empirical research. 3)

Limits: Where Empirical Evaluations fail

Empirical research offers many opportunities; however, there are at least two kinds of limitations: on the one hand, errors and pitfalls that are directly related to the layered evaluation approach, and, on the other hand, inherent limitations of empirical research in general. 3.1

General Problems of Empirical Research

Obviously, empirical studies are not a formal proof of a fact. They rather yield, support, or reject hypotheses. However, the results are always afflicted with uncertainty, which can often be expressed in a statistical probability value. Furthermore, for most statistical tests confidence intervals, test power, and effect sizes are available which should be reported as well. This hypothesis testing procedure is responsible for an important limitation of empirical research. Empirical studies are very good at identifying design errors and wrong assumptions but they do not suggest new theories or approaches directly. Even an explorative study requires some hypotheses about possible impact factors. Thus, empirical evaluations have to be combined with theoretical grounds to yield useful results. Not really a limitation but a structural reason why evaluations are currently ignored is the fact that evaluations are not required for publication at international conferences or journals (at least in terms of user modeling). Thus, the empirical part is often scheduled for the end of a project and finally skipped due to lack of time. If publishers and reviewers would demand empirical evaluations it would soon be an integrated part of research where empirical and theoretical components could stimulate each other. Moreover, AI systems are usually implemented by computer scientists who tend to be less familiar with empirical methods than people with training in human-computer interaction. When evaluating adaptive systems â&#x20AC;&#x201D; as opposed to IS / AI systems in general â&#x20AC;&#x201D; at least two additional problems emerge: first, defining adequate control groups is difficult for those systems that either cannot switch off the adaptivity, or where a nonadaptive version appears to be absurd because adaptivity is an inherent feature of these systems. Comparing alternative adaptation decisions might relieve this situation in many cases, as this allows to estimate the effect size that can be traced back to the adaptivity itself, but the underlying problem remains: What is a fair comparison condition for adaptive systems. Second, adequate criteria for adaptivity success are not well defined or commonly accepted: on the one hand, objective standard criteria (e.g., duration, number of interaction steps, knowledge gain) regularly failed to find a difference between adaptive 91

Management Systems

and non-adaptive versions of a system. Usually, these criteria have not been proved to be valid indicators of interaction quality or adaptivity success. On the other hand, subjective criteria that are standard in human-computer interaction research (e.g., usability questionnaires, eye tracking) have been applied to user modeling very rarely. Probably, the effects of adaptivity in most systems are rather subtle and require precise measurement. Recently, a new criterion called behavioural complexity has been proposed that has been designed especially for adaptivity effects but there is still much more work to be done on criteria validation. 3.2

Pitfalls and Errors Uncovered by the Layered Evaluation Approach

Keeping the above factors in mind, we have to note that there are still several pitfalls that have to be circumvented when conducting evaluations in the different layers. The evaluation of the reliability of input data relies heavily on a properly selected sample of participants, because retest-reliability and split-half reliability require a sufficient amount of variance in the observed variables. Furthermore, sample selection, sample size, and randomisation are important for the subsequent layers as well. Generalised statements about the inference mechanism are possible only if the observed effect is supposed not to be an artifact of a sample bias. The evaluation of inference will not allow for statements about every possible case including extreme values and special cases as a formal proof would. It will rather test the inference mechanism for external validity and feasibility under real world conditions. When comparing different adaptation decisions it is possible to select the best one in reference to several criteria. However, there might be unknown or unaccounted adaptation decisions that are even better, because the empirical approach compares of course existing versions only. It might be possible to escape from this limitation by using a human inference mechanism in a so called Wizard of Oz design (or similar approaches) as an additional control condition, because this might account as a benchmark of what adaptation might accomplish in this situation at all. However, this method is applicable only for those kinds of systems where humans are actually able to take over the inference processes, as opposed to systems that deal with large amounts of information or complex inferences. The evaluation of interaction highly depends on a precise and transparent goal setting. Interaction quality can be defined in many different ways, and thus, the result of such an evaluation will never be that “system A is better than system B in general”, but only “better in terms of goal X or goal Y”. 4)

Summary and Future Perspectives

It has been realised that empirical research offers a lot of opportunities that could inspire current research in IS/AI in general and in particular in user modeling. Empirical studies are able to identify errors in AI systems that would otherwise remain undiscovered. However, it has been largely neglected so far. In order to encourage new empirical evaluations of adaptive systems online database is available to researchers. This online database contains studies that are concerned with the evaluation of adaptive systems. Each study is categorised in terms of the layer that is evaluated, the criteria that have been used, the function and the adaptation method of the evaluated system(s), statistical methods, and many more dimensions. Researchers who want to evaluate their system get hints about useful criteria that did (or did not) work in previous studies. Proposals of experimental designs and evaluation strategies simplify the planning process. 92

Moreover, an online database could serve as reference for the usefulness of certain inference mechanisms and adaptivity in general. To provide a really useful service to the community, the number of registered studies should be expanded considerably. Thus, online database offers an online interface for study submission and everybody is invited to enhance such databases with new studies.

4.4 COST VALUE PERFORMANCE Investing in information systems can pay off for a company in many ways. 1)

Such an investment can support a core competency. Great companies invariably have one or two core competencies, something they can do better than anyone else. This could be anything from new product development to customer service. It is the heart of the business and no matter what it is, information technology can support that core competency. An IT investment in a companyâ&#x20AC;&#x2122;s core competency can create a significant barrier to entry for other companies, defending the organisationâ&#x20AC;&#x2122;s primary turf and protecting its markets and profits.

It can build supply chain networks. Firms that are a part of an integrated supply chain system have established relationships of trust with suppliers. This means faster delivery times, problem-free delivery and an assured supply. It can also mean price discounts and other preferential treatment. The inability of new entrants to get onto a supply chain / inventory management system can be a major barrier to entry.

It can enhance distribution channel management. As with supplier networks, investment in distribution channel management systems can ensure quicker delivery times, problem free delivery, and preferential treatments. When the distribution channel management system is exclusive, it can mean some control over access to retailers, and, once more, a barrier to entry.

Such an IT investment can help build brand equity. To build a brand, firms often invest huge sums in advertising. A huge brand name is a formidable barrier to enter and sustaining it can be facilitated by investment in marketing information systems and customer relationship management system.

Information systems can mean better production processes. Such systems have become essential in managing large production runs. Automated systems are the most cost efficient way to organise large-scale production. These can produce economies of scale in promotion, purchasing, and production; economies of scope in distribution and promotion; reduced overhead allocation per unit; and shorter break-even times more easily. This absolute cost advantage can mean greater profits and revenue.

IT investment can boost production processes. Information systems allow company flexibility in its output level it is claimed that economies of scale are a barrier to entry, aside from the absolute cost advantages they provide. This is because, a company producing at a point on the long-run average cost curve where economies of scale exist, has the potential to obtain cost savings in the future, and this potential is a barrier to entry.

Implementing IT experience can leverage learning curve advantages. As a company gains experience using IT systems, it becomes familiar with a set of best practices that are more or less known to other firms in the industry. Firms outside the industry are generally not familiar with the industry-specific aspects 93

of using these systems. New entrants will be at a disadvantage unless they can redefine the industry’s best practices and leapfrog existing firms.

Management Systems

IT investment can impact mass customisation production processes. IT controlled production technology can facilitate collaborative, adaptive, transparent, or cosmetic customisation. This flexibility can increase margins and increase customer satisfaction.

Leverage IT investment in computer-aided design. CAD systems facilitate the speedy development and introduction of new products. This can create proprietary product differences. Product differentiation can be a barrier to entry. Proprietary product differences can be used to create incompatibilities between competing products. These incompatibilities increase consumers’ switching costs. High customer switching costs is a very valuable barrier to entry.

10)

It means expanded E-commerce. Company web sites can be personalized to each customer’s interests, expectations, and commercial needs. They can also be used to create a sense of community. Both of these tend to increase customer loyalty. Customer loyalty is an important barrier to entry.

11)

Information systems leverage stability. Technologically sophisticated firms with multiple electronic points of contact with customers, suppliers, and others enjoy greater stability. This monumental appearance of stability can be a barrier to entry, especially in financial services.

The simple fact that IT investment takes a significant amount of money makes it a barrier to entry. Anything that increases capital requirements is a barrier to entry. The successful Information System implementation is a challenge, as it has to meet a number of critical business goals: deliver increasingly complex mission-critical business applications quickly and securely, and ensure that core business operations are strongly supported. Availability is critical as poorly performing applications have an immediate business impact, cutting revenue and alienating customers. These challenges must be met within the constraints of tight IT budgets and scarce internal corporate resources, while the external environment breeds new technology developments that determine how the enterprise derives competitive advantage. Therefore, evaluation of a system to ensure that it will meet the desired goals, before taking up its implementation, is necessary. Traditional Financial Evaluation Procedures For any capital investment almost all organisations carry out financial evaluation to ascertain the financial viability of the project or, in other words, any financial investment is taken up only if, as per this analysis value addition is expected. Capital planning, also known as “capital budgeting”, is an accounting process used to determine a firm’s long-term investments such as new machinery, replacement machinery, new plants, new products, new information system and research and development projects. As part of this process a financial analyst determines the economic value of business projects / ventures and allocates capital to those endeavours which present the greatest calculated return on investment. All capital budgeting methods rely on measures of cash flows into and out of the company. The investment cost is an immediate cash outflow caused by the purchase of the capital item. In subsequent years, the investment may cause additional outflows that will be balanced by the cash inflows resulting from the investments. Cash inflows may come from increased sales, higher realisation due to better quality of the product or better market share or reduced cost of the products. The difference between the cash outflows and cash inflows is used for calculating the financial worth of the project. 94

Once the cash flows have been established, several alternative methods are available for comparing different projects and deciding about the investment.

Business Values of Information System

Financial models assume that all relevant alternatives have been examined, that all costs and benefits are known, and that these costs and benefits can be expressed in terms of money. When one has to choose among many complex alternatives, these assumptions are rarely met in the real world, although they may be approximated. Some of the common costs and benefits are listed in the Table 1. Table 1: Costs and Benefits of Information System Implementation

Costs Hardware Software Infrastructure (Networking, telecommunications) Services Manpower Benefits (Tangible) Lower operational costs Increased productivity Reduced manpower Lower computer expenses Lower vendor services cost Lower clerical overheads Reduced facility maintenance cost Higher sales volume

Benefits (Intangible) Improved operations Better asset utilization Better resource control Better organisational planning Higher organisational flexibility Improved quality of information More Timely information Better Employee training Better employee morale Better corporate image Improved decision making Higher employee cooperation Better customer satisfaction Better environmental compliance Better legal compliance

Popular methods for determining the relative and absolute value of business projects / ventures include: Net Present Value (NPV), Internal Rate of Return (IRR), Discounted Cash Flow (DCF), and Payback Period. Net present value (or NPV) is a standard method in finance for capital budgeting – the planning of long-term investments. Using the NPV method a potential investment project should be undertaken if the present value of all cash inflows minus the present value of all cash outflows (which equals the net present value) is greater than zero. A key input into this process is the interest rate or “discount rate” which is used to discount future cash flows to their present values. If the discount rate is equal to the shareholder’s required rate of return, any NPV > 0 means that the required return has been exceeded, and the shareholders will expect an additional profit that has a present value equal to the NPV. Thus, if the goal of the corporation is to maximize shareholders’ wealth, managers should undertake all projects that have an NPV > 0, or if two projects are mutually exclusive, they should choose the one with the highest positive NPV. Net present value - Example X Corporation must decide whether on not to introduce a new information system or product line. The new information system or product will have startup costs, operational costs, and incoming cash flows over six years. This project will have an immediate (t = 0) cash outflow of Rs.100,000 (which might include hardware, and employee training costs). Other cash outflows for years 1-6 are expected to be Rs. 5,000 per year. Cash inflows are expected to be Rs. 30,000 per year for years 1-6. All cash flows are after-tax, and there are no cash flows expected after year 6. The required rate of return is 10%. The present value (PV) can be calculated for each year: 95

Management Systems

T=0 –Rs. 100,000 / 1.10^0 = – Rs. 100,000 PV. T=1 (Rs. 30,000 – Rs. 5,000)/ 1.10^1 = Rs. 22,727 PV. T=2 (Rs. 30,000 – Rs. 5,000)/ 1.10^2 = Rs. 20,661 PV. T=3 (Rs. 30,000 – Rs. 5,000)/ 1.10^3 = Rs. 18,783 PV. T=4 (Rs. 30,000 – Rs. 5,000)/ 1.10^4 = Rs. 17,075 PV. T=5 (Rs. 30,000 – Rs. 5,000)/ 1.10^5 = Rs. 15,523 PV. T=6 (Rs. 30,000 – Rs. 5,000)/ 1.10^6 = Rs. 14,112 PV. The sum of all these present values is the net present value, which equals Rs. 8,882. Since the NPV is greater than zero, the corporation should invest in the project. More realistic problems would need to consider other factors, generally including the calculation of taxes, uneven cash flows, and salvage values. Net present value - Formula Net Present Value can thus be calculated by the following formula, where t is the amount of time (usually in years) that cash has been invested in the project, N the total length of the project (in this case, five years), i the cost of capital and C the cash flow at that point in time.

NPV =

∑ (1 + i) t =0

if the only cash outflow is the initial investment, then the formula may be written: NPV =

∑ (1 + i) t =1

− Initial Investment

The above example is based on a constant rate being used for future interest rate predictions and works very well for small amounts of money or short time horizons. Any calculations which involve large amounts or protracted time spans will use a yield curve to give different rates for the various time points on the calculation. So, the rate for 1 year may be 10% - the (money market) rate while the rate for 2 years may be 11% and that for 3 years 11.5%, and so on. Internal rate of return (IRR)

The internal rate of return (IRR) is defined as the discount rate that gives a net present value (NPV) of zero. The NPV is calculated from an annualized cash flow by discounting all future amounts to the present. Example:

Year Cash flow 0 –100 1 +120 Calculation of NPV:

i = interest rate in per cent NPV = –100 +120/[(1+i/100)^1] (This calculation is condensed; as the detailed calculation has already been explained above.) Calculation of IRR (in per cent):

NPV = 0 –100 +120/[(1+IRR/100)^1] = 0 IRR = 20 96

As an investment decision tool, the calculated IRR is used to rate alternative investments. The investment alternative with the highest IRR is preferred. Note that placing the initial investment amount in the bank is always an alternative. Thus, any investments that do not match the banks going deposit rate will not be realised.

Business Values of Information System

It should also be noted that zeros of NPV as a function of IRR may lack existence or uniqueness if there is some alternation of positive and negative cash flow. The IRR exists and is unique if one or more years of net investment (negative cash flow) are followed by years of net revenues. In general, the IRR can be calculated by solving a polynomial. Sturm's Theorem can be used to determine if that polynomial has a unique real solution. Importantly, the IRR equation cannot be solved analytically (i.e., in its general form) but only via iterations. A critical shortcoming of the IRR method is that it is commonly misunderstood to convey the actual annual profitability of an investment. However, this is not the case because intermediate cash flows are almost never reinvested at the project's IRR; and, therefore, the actual rate of return (akin to the one that would have been yielded by stocks or bank deposits) is almost certainly going to be lower. Accordingly, a new measure called Modified Internal Rate of Return (MIRR) is used. In spite of a strong academic preference for NPV, surveys indicate that executives prefer IRR over NPV. Apparently, managers find it intuitively more appealing to evaluate investments in terms of percentage rates of return than Rs of NPV. Discounted cash flow (DCF)

A discounted cash flow or DCF is the value of a cash flow adjusted for the time value of money and is a form of present value analysis. The nominal values of two cash flows (positive or negative) in different time periods cannot be directly compared because of the preference of most people for consumption sooner rather than later. The presumption behind this principle’s that a dollar in your hand today is worth more than a dollar you may receive at some point in the future: or, more colloquially, “a bird in the hand is worth two in the bush”. Similarly, a dollar you have to spend three years from now costs you less than a dollar you have to spend today. This is due to opportunity cost and risk over time. Opportunity cost is significant because any financial decision must be measured against a default low-risk investment alternative (usually the rate of a Treasury bond of similar yield period) or the inflation rate. Risk becomes a significant factor when the financial decision being considered involves some statistically significant probability of loss. Calculation of risk factors beyond opportunity cost can often be very complex and imprecise, requiring the use of actuarial analysis methods and in-depth market analysis. When risk is included in DCF analysis, it is generally done so according to the premise that investments should compensate the investor in proportion to the magnitude of the risk taken by investing. A large risk should have a high probability of producing a large return or it is not justifiable. By combining assessments of both opportunity cost and risk, a discount rate (or “hurdle rate” if the DCF analysis is being used to set future business performance expectations) is calculated for the analysis of the present value of anticipated future cash flows. Discounted cash flow analysis is widely used in investment finance, real estate development, and corporate financial management.

Management Systems

Formula

The discounted cash flow formula is derived from the future value formula for calculating the time value of money and compounding returns. FV = PV .(1 + i ) n

The simplified version of the Discounted cash flow equation (for one cash flow in one future period) is expressed as:  1  DPV =  * FV n   (1 + d )  Where

DPV is the discounted present value of the future cash flow (FV), or FV adjusted for the opportunity cost of future receipts and risk of loss; FV is the nominal value of a cash flow amount in a future period; d is the discount rate, which is the opportunity cost plus risk factor (or the time value of money: "i" in the future-value equation); n is the number of discounting periods used (the period in which the future cash flow occurs). i.e., if the receipts occur at the end of year 1, n will be equal to 1; at the end of year 2, 2—likewise, if the cash flow happens instantly, n becomes 0, rendering the expression an identity (DPV=FV). Where multiple cash flows in multiple time periods are discounted, it is necessary to sum them as follows: DPV =

FVt

∑ (1 + d ) t =0

For each future cash flow (FV) at any time period (t) for all time periods. Example DCF

To show how discounted cash flow analysis is performed, consider the following simplified example. Ram Dass buys an Information system for Rs. 100,000. Three years later, he expects to be able to sell his product with addional Rs. 150,000 because of improved marketability of his product by using the Information system. Simple subtraction suggests that the value of his profit on such a transaction would be Rs. 150,000 – Rs. 100,000 = Rs. 50,000, or 50%. If that Rs. 50,000 were amortized over the three years, his implied annual return (known as the internal rate of return) would be about 13.6%. Looking at those figures, he might be justified in thinking that the purchase looked like a good idea. However, since three years have passed between the purchase and the sale, any cash flow from the sale must be discounted accordingly. At the time Ram Dass buys the Information system, the 3-year Treasury Bill rate is 5%. Treasury Bills are generally considered to be inherently less risky than real estate, since the Government guarantees the value of the Bill and there is a liquid market for the purchase and sale of T-Bills. 98

So, calculating exclusively for opportunity cost, we get a discount rate of 5% per year. Using the DCF formula above, we see that the net present value of Rs. 150,000 received in three years is actually Rs. 129,146 (rounded off). Those future rupees aren’t worth the same as the rupees we have now.

Business Values of Information System

Using simple subtraction again, the present-value profit on the sale would then be Rs. 29,146 or a little more than 29%. Amortized over the three years, that implies a discounted annual return of 8.6% (still very respectable, but only 63% of the profit he previously thought he would have). Note that the original internal rate of return (13.6%) minus the discount rate (5%) equals the discounted internal rate of return (8.6%). The discount rate directly modifies the annual rate of return. But what about risk? The Information system Ram Dass is buying is a “good system”, but market values have been rising quite a lot lately and the market analysts in the media are talking about a slow-down and higher interest rates. There is a probability that Ram Dass might not be able to get the full Rs. 150,000 he is expecting in three years due to a slowing of price appreciation, or that loss of liquidity in the product market might make it very hard for him to sell at all. For the sake of the example, let’s then estimate his risk factor is about 5% (we could perform a more precise probabilistic analysis of the risk, but that is beyond the scope of the study material here). Therefore, this analysis should now include both opportunity cost (5%) and risk (5%), for a total discount rate of 10% per year. Going back to the DCF formula, Rs. 150,000 received three years from now and discounted at a rate of 10% is only worth Rs. 111,261 (rounded off) in present-day rupees. The present-value profit on the sale is now down to Rs. 11,261 discounted rupees from Rs. 50,000 nominal Rupees. The implied annual rate of return on that discounted profit is now 3.6% per year. That return rate may seem low, but it is still positive after all of our discounting, suggesting that the investment decision is probably a good one: it produces enough profit to compensate for opportunity cost and risk with a little extra left over. When investors and managers perform DCF analysis, the important thing is that the net present value of the decision after discounting all future cash flows should at least be positive (more than zero). If it is negative, that means that the investment decision would actually lose money even it appears to generate a nominal profit. For instance, if the expected addional sale price of Ram Dass’s product in the example above was not Rs. 150,000 in three years, but Rs. 130,000 in three years or Rs. 150,000 in five years, then buying the Information system would actually cause Ram Dass to lose money in present-value terms (about Rs. 6,000 in the first case, and about Rs. 9,000 in the second). Similarly, if the Information system was not yielding the desirable results and the Reserve Bank was about to raise interest rates by five percentage points, then the risk factor would be a lot higher than 5%: it might not be possible for him to make a profit in discounted terms even if he could sell the product for addional Rs.200,000 in three years. In this example, only one future cash flow was considered. For a decision, which generates multiple cash flows in multiple time periods, DCF analysis must be performed on each cash flow in each period and summed into a single net present value. Pay Back Period

Pay Back Period is the time required to pay back the initial investment of the project. The payback period is computed as 99

Management Systems

Number of years to pay back =

Original Investment Actual Net Cash flow

The payback period method is a popular method because of its simplicity and power as an initial screening method. It is especially suited for high risk projects in the which useful life of the project is difficult to assess. If a project pays for itself in three years, then it hardly matters how useful the system remains after three years. The weakness of this method lies in its not considering the time value of money, the amount of cash flows after the payback period. Limitations of Traditional Financial Evaluation Procedures

Assessment of benefits in case of the Information Systems implementation are more difficult and variation in actual and expected benefits may be larger because of the following factors: •

IS implementation is closely related to organisational culture and therefore may vary from organisation to organisation; in other words the assessment has to be organisation specific.

•

IS implementation in bulk of the cases presents a first time case situation; therefore, previous data is not available.

•

IS implementation in many cases undergoes change during implementation so initial estimates may be quite different.

•

Valuation of intangible factors may be subjective or may not be possible at all.

•

Time over-runs and cost over-runs may be there.

•

It does take into account risk factors.

•

It does not take into account the strategic considerations.

Other Methods of Evaluation

The conventional financial budgeting systems do not take into consideration the strategic considerations, while the other methods namely Real options pricing models, scoring models and portfolio analysis involve strategic considerations. Real options pricing model and scoring model are discussed in detail here, while portfolio analysis will just be briefly touched upon here as it is being discussed in detail in unit 5. Real Option Pricing Model

100

The Real option pricing model makes it possible to arrive at the strategic decision whether a project needs to be taken up immediately or later? When will it be more beneficial? This will be clear from the example showing how the flexibility of a project is important in evaluating the project’s benefits. You want to buy an Information System module for your works to improve productivity. You find that two types of systems are available, one (costing Rs. one million) covering production planning for the present models of the cars being manufactured and the other one (costing Rs. 1.2 million) covering besides present models, the additional models that the company is planning to cover. The additional models are expected only after next two years. All other factors in both the modules are same. You end up comparing two information systems that are identical, with the exception that one takes care of new models also. Not surprisingly, the system covering additional models is more expensive. Why would you even consider buying the second system? Because of the added flexibility that the second system provides for future models also. Is the flexibility of the second system worth Rs. 0.2 million is going to depend on variables such as the time when new models are started, what will be sale volume of those

models, and cost and profit margin? Complicating the process is the fact that the value for the variables will change over time. In the end, it comes down to a subjective judgment on your part whether the additional Rs. 0.2 million cost for the new model is worth it.

Business Values of Information System

If you get together with a group of managers to discuss which of the two systems to buy, without any doubt all will agree that the second system is more flexible. However, it is certain that there won’t be complete agreement on how valuable the flexibility difference is between the two systems. On the other hand, if you develop a real options model of the decision you might find that the added flexibility of the second system is worth Rs. 0.27 million. Since the additional cost would be less than that (i.e., Rs. 0.2 million), buying the second system would be worthwhile. Types of Real Options

Real options have been broken down into six categories based upon the type of flexibility provided. The six categories are: the option to defer; the option for staged investments; the option to change scale; the option to abandon; the option to switch; and the option to grow. The option to defer occurs when you can put off a decision until some date in the future. This allows management to determine if resources should be spent on a project at that future date. For example, your long lost uncle leaves you a gold mine instead of cash. A trip to the mine shows you that there is gold in the mine; however, the cost of removing the gold is more than the gold is worth. If you keep the mine, you have to pay a small property tax on the land every year. Paying the small tax allows you to defer the decision on whether to extract the gold. Right now the gold is essentially worthless, but the price of gold might suddenly sky rocket making the cost of extracting the gold worthwhile. Therefore paying the small tax allows you to delay a decision on whether to extract the gold if conditions change. The option for staged investments occurs when a project investment happens in a series of outlays that allows the project to be abandoned mid-stream if conditions become unfavourable. The development of a project can be considered to be a series of options. Each stage in development can be considered an option on the value of future stages. You decide you want to convert the gold mine you inherited in the previous example to a tourist attraction. You draw up the plans for a theme park, however, you build only one concession stand at first. If people really enjoy your attraction, you can expand the concession stand and add a ride. On the other hand, if there is suddenly an overabundance of gold mine attractions, you don’t have to expand your concession stand. Thus building in stages allows you to abandon or change the project if future conditions deteriorate. The option to change scale can result in the project being expanded, contracted, or shut down and restart. Depending on market conditions that prevail at a particular time, the rate of resource expenditure can be adjusted to meet the new conditions. For example, you have decided to replace your personal computer. You go to your local computer superstore and see what is available. Presently you are using your computer only for word processing and spreadsheets. You don’t really need a high end color monitor, 32 megabytes of memory, and a 2 gigabyte hard drive. So why don’t you buy a stripped down system that is adequate for your existing needs? Because, you don’t know, what you will need to do tomorrow with your machine. You might suddenly have to develop a World Wide Web site for your company or put together presentations, or suddenly your kids decide they “need” to have the latest games. Even if your needs don’t change, the existing software you use may be revised and you no longer have the capability to run the new versions on your machine. Thus, you go with the machine that is more powerful than your existing needs so that if your needs expand, you do not have to start over and purchase a new machine. 101

Management Systems

The option to abandon allows the company to abandon a project if the market conditions drop dramatically. The company can then sell off any assets available to offset the loss or switch those assets to other projects. For example, you buy a new IBM PC to be able to work at home. Suddenly, your company decides to switch from PC to Macintosh and you need to get a new computer. Fortunately, your teenage daughter is going away to college in a couple of months and will be required to buy a PC. So you now turn over your PC to your daughter and no longer have to buy her one. Therefore, even though the PC cost Rs. 30,000, you didnâ&#x20AC;&#x2122;t lose all the value when you abandoned it. Rather you shifted the resource to another location where it was still valuable. The option to switch allows an organisation to change either the input mix or output mix of a facility. If environmental conditions change, this option provides the flexibility to alter either the process (i.e., input mix) or product (i.e., output mix). The option to grow is used when an initial investment is required for further development. The project can be considered a link in a chain of related projects. Each project in the link is required for future growth. An organisation may invest in research and development even though it typically has a negative value when looked at in isolation. It invests because of the future growth value of the results of that research and development. For example, you are convinced that your gold mine attraction will be a winning idea but presently the only way to reach the gold mine is by a one mile burro ride. You decide to build a road to connect your gold mine with the highway. Looking at the costs and benefits of the road in isolation, the costs outweigh the benefits and it does not make sense to put in the road. However, you realize that without the road, the rest of the project is not feasible. Therefore, you decide to build the road even with its negative cost analysis because it is required as part of the first stage in developing your gold mine attraction. Many projects do not have only a single real option that is applicable to them. Depending on the type of project, more than one real option may need to be considered when computing the value of the real options. For example, we used the same gold mine example in three of the cases above. However, it is important to realise that these real options can interact in various ways. The value of the interacting multiple options may not be equivalent to the value of the individual real options added together. Scoring Models

For arriving at a decision on alternative systems scoring model is a quick and suitable method. This method gives alternative systems a single score based on the extent to which they meet selected objectives. This method is illustrated in Table 4 In this example a firm has to choose one of three alternatives office systems (a) a UNIX based client / server system using an Oracle data base, (b) a Window based client / server system using Windows XP, Windows.Net server and Lotus Notes, and (c) an IBM AS/400 client server system with proprietary software. As shown in the Table 2 column 1 indicates the criteria that decision makers agree to apply on the systems. Column 2 lists the weight that decision makers attach to the decision criteria. Now the decision makersâ&#x20AC;&#x2122; move on to the next step of ranking the systems for each criterion based on the degree of user needs each system meets for that criterion. The system getting the highest score is considered / evaluated the best and selected. In this example Windows XP is the preferred system. The crucial aspect of this method lies in the fact that the decision makers have to agree on the criteria of selection, their weights and the final score for each criteria for each option. Thus the system chosen is based on consensus decision. 102

This method enables selection from alternative systems based on strategic and risk considerations. This will be discussed in detail in unit 5.

4.5 TOTAL COST OF OWNERSHIP The total cost of ownership (TCO) of an information system is defined as the total cost of acquiring, implementing, and keeping that system running. It’s an accounting methodology that today is proving to be crucial in making sound IT decisions. Many IT professionals conveniently factor in only the costs of purchasing hardware and software when doing TCO analysis. This isn’t surprising; when pressed for time, they only take into account what’s easy to find out. In the relatively easy-to-manage world of mainframes and big centralized information systems, hardware and software accounted for much of the cost factors. In the current era of e-business, client /server, and peer-to-peer systems, however, the costs of managing and maintaining information systems is often much higher and cannot be ignored. Cost factors, which should go into the computation of the TCO of any system, can be grouped into direct and indirect costs. Direct costs pertain to the acquisition expenses or the cost of buying the system, and cover all of the following activities:

•

Researching possible products to buy, which is essentially a labour cost but may also include materials cost, such as purchase of third-party research reports or consultant fees.

•

Designing the system and all the necessary components to ensure that they work well together. Naturally, this cost component will be higher if a move to a totally different system platform is being considered.

•

Sourcing the products, this means getting the best possible deal from all possible vendors through solicited bids or market research. It’s often sufficient to get a quotation from three vendors (with the cheapest one not necessarily being the best choice). With the Internet, it’s easy to get price quotations even from sources outside the country, to get a good spectrum of pricing options.

•

Purchasing the product(s), which includes the selling price of the hardware, software, and other materials as negotiated with the chosen suppliers. Include all applicable taxes that might be incurred. Don’t forget to consider the costs of the 103

systems at the end-user side; some system choices might entail a change or upgrade at that end.

Management Systems

•

Delivering the system, which includes any shipping or transportation charges that might be incurred to get the product into its final installation location.

•

Installing the system. Bear in mind that installation also incurs costs in utilities and other environmental — not just labour costs. If the installation of the system will result in downtime for an existing system, relevant outage costs must be included. Any lost end-user productivity hours during this activity should also be factored in.

•

Developing or customizing the application(s) to be used.

•

Training users on the new system.

•

Deploying the system, including transitioning existing business processes and complete integration with other existing computing resources and applications. Include here the costs to promote the use of the new system among end users.

•

Indirect costs address the issues of maintaining availability of the system to end users and keeping the system running, which includes the following:

•

Operations management, including every aspect of maintaining normal operations, such as activation and shutdown, job control, output management, and backup and recovery.

•

Systems management, such as problem management, change management, performance management, and other areas.

•

Maintenance of hardware and software components, including preventive maintenance, corrective maintenance, and general housekeeping.

•

Ongoing license fees, especially for software and applications.

•

Upgrade costs over time that may be required.

•

User support, including ongoing training, help desk facilities, and problemresolution costs. Remember to include any costs to get assistance from thirdparties, such as maintenance agreements and other service subscriptions.

•

Environmental factors affecting the system’s external requirements for proper operation, such as air conditioning, power supply, housing, and floor space.

•

Other factors that don’t fall into any of the above categories, depending on the type of system deployed and the prevailing circumstances.

All these cost factors seem fairly obvious, but quantifying each cost is difficult or impractical in today’s world, because few organisations have an accounting practice that’s mature enough to identify and break down all these types of expenses in sufficient detail. For example, very few organisations record all employee activities by task and hours used—information you would need to answer questions like these: What support costs did you incur last month? How much time did each user spend in solving computer-related problems? How much work was lost due to downtime on desktop PCs? 104

Additionally, companies rarely have accurate inventory and asset information regarding their computing systems, especially in large, multi-location computing environments where PC, server, and local network purchasing decisions are often handled at the department level.

Business Values of Information System

So, what’s the value of knowing a system’s TCO? Obviously, our objective is not to calculate exact figures. Rather, you need to understand what these costs could reasonably be in your organisation. You must plan for these costs, even if you can only roughly estimate them. A fair amount of intelligent “guesstimation” is much better than blindly deciding on an IT solution on the basis of sticker price alone. In addition, TCO analysis provides a good basis of comparison between alternative system-deployment strategies, between platform choices, and between competing products. Industry TCO Estimates

When IT and user labour costs are factored in, industry consultants have estimated the TCO of typical office PC systems from as low as Rs. 120,000 to as high as Rs. 400,000 per unit, per year. Note that typical PC hardware and software prices range from a low of Rs. 30,000 to a high of Rs. 80,000 for desktop units. An example of how TCO can help in making a decision on system migration is a recent analysis by the Gartner Group that estimates the migration costs per PC system going from a Windows 98 to a Windows 2000 platform to be anywhere from Rs. 80,000 to Rs. 120,000. The same sort of analysis by Giga Group — but quantifying the labour savings gained — puts the cost of migration at Rs. 38,000 per system. In Giga Group’s approach, they tried to quantify the gain in user productivity hours from the use of the much more stable Windows 2000 operating system. Although all analyst’s TCO estimates vary considerably, they all point to the fact that – •

TCO results will be very different for every organisation, given their varied computing environment, user experience level and IT expertise.

•

PC systems have much higher indirect costs than direct costs.

•

TCO analysis is never going to be an exact science, due to the many assumptions and unknowns that have to be taken into account.

•

As you provide more functionality and capability to end users, TCO rises. As you install more software or provide more complex hardware at the hands of end users, you pay increasingly more for support and maintenance.

TCO provides a good model for evaluating computing costs — direct and indirect, visible and invisible, budgeted and unbudgeted. Of course, TCO cannot be your sole determining factor for choosing a computing system. What we are driving at here is that you should be aware of these costs and plan for them. At the same time however, you must always balance the costs of providing a system versus the benefits it brings to the business and the end users. Many decisions you make will not be due to cost-avoidance but rather on the basis of business advantage. A case in point is having Internet connectivity. On the one hand, providing such a facility for the enterprise means additional investments in firewalls and other security products, as well as a dramatic rise in potential damage from hackers, viruses, and other malicious activities. But on the other hand, what business can adequately compete or even survive without the access to information, worldwide reach, and accessibility to customers that the Internet provides? 105

Management Systems

What TCO Studies Reveal

TCO studies of PCs, PDAs, and other end-user – oriented computing platforms have identified several key, hidden, and oftentimes un-budgeted costs due to the following phenomena: Fiddle factor: Users often spend excessive time changing minor look-and-feel items on their systems — time that could instead be spent performing productive work. Examples include changing how the Windows desktop looks (color, size, icons, screensavers), installing applets or utilities (pop-up messages, animated cursors, desktop accessories), and trying out different fonts or lettering styles in documents. These activities distract users from the more important task of ensuring quality content in their work. Peer support and self-help phenomena: When end users encounter problems, they rarely seek IT help. They either try to solve the problem on their own or ask colleagues to assist, taking themselves and their co-workers away from primary job responsibilities. Not only that; as users try to gain as much computer expertise as possible, they often neglect the skills they need in their line of work. Most of their computer skill is learned informally, by time-consuming experimentation that often causes even more complex problems. User-introduced problems: Often, users themselves cause unnecessary downtime and lost productivity through activities such as these:

Deleting critical system files by accident or experimentation. Changing parameters in the Windows system registry, control panel, and other configuration files. Installing new software that causes system instabilities, security exposures, or counterproductive activities (for example, utilities or games).

The Underlying Reason for High TCO

Where a company’s systems have especially high TCO, its systems were most likely deployed with only the following objectives in mind: •

Functionality: The capability of a computer to perform the tasks and run the applications required by the user.

•

Performance: The capability of a computer to respond to user input as quickly as possible (often referred to as system response time).

•

Capacity: The capability to handle growth in concurrent users, amount of data processed, number of transactions completed, or other metrics.

After the systems are deployed, issues not directly related to these criteria crop upissues that prove every bit as important to users over the long term. These postdeployment requirements include •

Availability: The system or application is there when the user needs it.

•

Ease of use: No complicated procedures to learn or remember.

•

Assistance: If the user has a problem, help is easily accessible.

• Security: The user’s work is protected from loss or unauthorized access. In all cases where the TCO of a system is unnecessarily high, it's because the system or application was designed without taking into consideration the post-deployment user requirements above, particularly availability, security, and assistance. 106

Availability as the Most Significant Contributor to TCO

Experience with information systems has shown us that the user requirement responsible for the greatest hidden costs is availability. This user requirement takes precedence over all others: What good is a system if it’s unavailable? Availability also requires ongoing management and maintenance throughout the entire life of every system.

Business Values of Information System

A system is considered available when users can work with it without experiencing outages. Availability is measured from the user’s point of view. It deals not only with the prevention of real system outages, but with user-perceived outages as well. These perceived outages are anything that prevents the user from working with the system productively, such as prolonged response times, lack of assistance, or lack of available workstations. As long as the user doesn't perceive or feel the outage, the system is considered “available.” A user will consider a system unavailable if one of these conditions occurs: •

The system is not accessible: If the user can’t access the resources s/he needs to run an application, the system is considered unavailable. The system is equally unavailable if all workstations or software licenses are in use, or if the network connection to necessary data is down, or if the system has a virus infection.

•

The system is running too slowly: The system may be operational, but if the response time is long the user will give up waiting and consider the system as unavailable.

•

The system is intermittently having problems: The user will choose not to use a system if s/he suspects that work may be lost due to intermittent system failures.

TCO Summary

In today’s widely distributed IT computing environment, we must understand TCO in order to effectively evaluate all of our deployment alternatives. All studies on TCO have shown that the TCO of interconnected servers, workstations, and intelligent access devices is higher compared to the centralised mainframe and dumb terminals of yesteryear, and the key reason is the lack of attention to post-deployment system requirements, especially the availability requirement. If a system is designed, deployed, and managed without special attention to organisation, people, process, and technology issues, the total cost of ownership will definitely spiral out of control.

4.6 CULTURE FOR INFORMATION SYSTEMS Culture is a multi-faceted entity that is hard, if not impossible, to define. For our purposes, we can start with an understanding of culture as the totality of shared meanings and interpretations of a given group. This repository of shared understandings and interpretations of the world is represented by symbols whose meanings and interpretations, members of the same culture share. The exchange of meanings and the agreement on appropriate interpretations of symbols is linked closely to communication. Without communication, no culture could exist, which, in turn, underlines the social nature of culture.

This is a rather wide understanding of culture that requires further specification. It is useful, however, because it allows an understanding of culture as a multiple phenomenon with areas of overlap and frequent change. For example, it facilitates cultures of different reach, such as organisational culture and national culture. Most 107

Management Systems

organisations will have some particularities that are meaningful to their members, and that outsiders cannot access easily. Thus, they fulfil the definition of culture, and arguably, they require a culture in order to facilitate their long-term survival. A similar description can be found for national cultures; namely, that they are the collection of things, ideas, and techniques, including institutions, that a society needs, to persist. It should be clear that such a definition of culture would not allow easy delimitations and distinctions. Most individuals will be members of a variety of cultures (i.e., company, sports club, ethnic group, nation, region). These memberships may be mutually reinforcing, but they also may be contradictory. An important aspect of culture is that it has a normative function. This means that cultures contain an idea of how things should be and how its members are expected to behave. This means that they are inherently utopian and imply a good state of the world. There are different ways in which the normative character of cultures is transmitted. One of these ways is what we usually call ethics or morality. This refers to the norms that are accepted in a given culture and the justification of such norms. It also can be translated in terms of values that are implicit in all cultures. Therefore, one can say that culture is a “value concept”. A related and very important aspect is that of religion. Religions, too, contain shared symbols and meanings and provide their members with normative guidance. Religions, therefore, can be seen in this context as a subset of cultures but as an important one, which strongly affects different cultures. All of this should render it clear that cultures are linked deeply to questions of identity. On an individual level, identity as the answer to the question, “Who am I?” is answered by a collection of narratives. These narratives draw on the cultures of which the individual is a member. Clashes of cultures, therefore, can lead to contradictory influences on identity and to cognitive dissonance, which can lead to pathological developments. Culture, thus one can claim, is a universal ingredient of human existence. Humans are symbol-using beings who live in a largely self-constructed environment, require continued cooperation to survive, and cannot live without culture. Thus, culture is a necessary ingredient of all communities and societies. At the same time, cultures also can be problematic. The fact that they determine their members’ views of reality and morality means that they are close to and easily used by ideology. A culture can justify and help appear normal the things and actions that appear repulsive and immoral to other cultures. This leads us to the difficult question whether there are universal aspects of all cultures that would allow cross-cultural dialogue aimed at addressing such contradictions. Traditionally the information systems (IS) designers have followed simple concepts of organisational functioning based overwhelmingly on ideas of management control. Data from operational activity is processed for use as information for management to use in planning, decision-making and supervision. While this viewpoint fits some organisations it is not appropriate to all. Organisational culture and national culture, may be readily overlooked by the IS designer. We will discuss the major dimensions of the impact of culture on an organisation’s information systems. Culture and Information System

Inside working organisations, as in all areas of human activity, the behavior of people is affected by the values and attitudes that they hold. The collective patterns of behaviour are important parts of the culture of the work-group or nation, which form a backdrop against which values and attitudes are in turn developed. This cycle is shown in Figure 4.

Data only becomes information when a person interprets it, and this interpretation of necessity takes place against the backdrop of the individual's culture. In decisionmaking, information is a prerequisite and the decision-making process is deeply affected by culture. Thus the meaning of information and effectiveness of an information system can vary substantially in different cultures. National cultures have long been associated with differences in the organising and operating of businesses and, more recently, cultures specific to organisations have been given due importance. It is today an established realisation that the nature and role of information is central to the organisations, and, just as emphatically, the culture has a critical impact on the selection, analysis and design of information systems. The first step for the IS designer, before any systems investigations are commenced, has to be a study of the organisationâ&#x20AC;&#x2122;s culture, and in the case of transnational and multinational systems, the national cultures involved. These will give warnings of modes of information handling, supervision and control that will be intimately concerned in any information system to be introduced. National culture

The importance of national values as they impact upon corporate culture has been well established. A clear link from Japanese national culture to the corporate cultures of major organisations and then to the outstanding success of Japanese business has been an established fact. The interest of some of the top leaders of Indian industry was the possibility of transferring or creating Japanese-like corporate values (and hence culture) in Indian industry in order to generate similar successes. It was found that some Indian organisations already had cultures much like Japanese organisations and, it was felt, this was significant in their success. Dimensions of power distance and uncertainty avoidance may be of great significance to the IS designer, especially if the values are extreme, that is, very high or very low. Such extreme values can lead to systematic rejection of information that conforms to recognisable types. Other extreme values may lead to over-reliance on information to the detriment of the organisation. By being aware of the environment the IS designer may be able to foresee some of the dangers. These are most acute for a designer who is not a national of the country where development is taking place. The dangers can be summarised briefly as: If uncertainty avoidance is strong then an MIS is needed to try to reduce the uncertainty even if that is impossible; systems may become rituals, If uncertainty avoidance is weak, fatalism leads to skepticism about MIS and resistance from users, If power distance is large then the boss disagrees with the MIS and the boss is right, If power distance is small, authoritative approaches will be risky.

Management Systems

Organisational / Corporate Culture

One common thread that greatly affects many of the organisational aspects that enhance performance and increase productivity is the widely shared and strongly held values that underlie and define an organisation’s culture. Organisational (or corporate) culture can be defined as “the pattern of shared values and beliefs that help individuals understand organisational functioning and thus provide them with the norms for behaviour in the organisation. Culture can also provide a key to understand issues such as “why things happen the way they do,” and in understanding organisational climate as “what happens around here.” Cultures can be determined by the values, assumptions and interpretations of organisation members. These factors can be organized by a common set of dimensions on both psychological and organisational levels to derive a model of culture types to describe organisations. Corporate culture is an important predictor of organisational capabilities and outcomes such as customer orientation and new product development. For many years, scholars in organisational behaviour have also attempted to demonstrate the link between an organisation’s culture and its performance. It has been argued that the success of an organisation’s strategy depends, to a significant extent, on the culture of the organisation. In considering culture in the light of a strategic management paradigm, it has been argued that, for an organisation’s culture to provide sustained competitive advantages, it must add value. It must be rare or unique and be difficult to imitate by competitors. Step 2

Figure 5: Information flow and adoption

Information System Adoption

Figure 5 provides an overall illustration of how an organisation adopts an information system and the numerous factors that influence the adoption process. A whole range of economic, social, political and technological factors that influence decision-making and performance surrounds an organisation. Other factors in the external environment constitute the organisation’s customers, distributors, suppliers and the competition. These forces constitute the external macro-environment as well as microenvironment forces. They need to be scanned to determine opportunities and threats for the business. The internal environment of the organisation could be made up of tangible factors such as the physical plant and equipment and the intangible factors such as the skills of the employees within the organisation. To be able to survive in the highly 110

competitive business world, a business must identify its strengths and weaknesses, sharpen its core competencies and leverage them for competitive advantage. The important role IS plays in business is well known.

Business Values of Information System

Thus, the current information technology system of an organisation constitutes the center of IS influences (step 1). Such influences could be made up of old legacy systems, integrated systems, semi-integrated systems or stand-alone Information Systems. Depending on the organisational size, the market nature and type of products being produced and the perceived benefits of IS, certain portals are able to penetrate the organisation to varying degrees to influence adoption (step 2). Penetration and adoption are typically facilitated by top management, cultural orientation of the organisation, management information systems or the information technology itself as alluded to in earlier sections of this unit. Once these factors have successfully penetrated the organisation to influence the adoption of IS, internal diffusion occurs (step 3). The diffusion is considerably affected by the cultural orientation of the organisation to create strong or weak relationships of the factors that lead to the penetration, adoption and diffusion. Based on the corporate culture with respect to IS adoption, the organisation may utilise IS for internal consumption (Intranet), external consumption (Extranet), a network of computer networks for global application (Internet) database management, enterprise resource planning and many other IS applications (step 4). In the highest order application of IS, e-Business takes place with interorganisational connectivity (step 5). This can be done with its exchange partners, such as its customers, which include order taking, order process, order payment, dispatch, order tracking and after-sales customer support. Others include suppliers for procurement processes and overall supply chain management. Corporate Culture Impact on Information System Adoption

The established factors of corporate culture having deep impact on the Information system are shown in Figure 6. These factors have been discussed one by one. Extent of IS Applications User Participation

Figure 6: Impact of corporate culture on information system

Extent of Application

The â&#x20AC;&#x153;extent of applicationâ&#x20AC;? factor describes the extent to which an organisation applies IT to making, implementing and evaluating organisational decisions. Its benefits are commonly based on enhanced decision-making or improved business performance. The use of information in decision-making involves integrating information sources and selecting from among alternative strategies, whereas information use in decision implementation concerns how decisions should be carried 111

Management Systems

out. Information use in evaluation, on the other hand, refers to the determination of positive and negative performance outcomes and the reasons for the outcomes. The development of IT comes with a significant risk of whether the end users will actually use it or not. To ensure continued use, external variables (such as technical features and organisational environment), internal psychological variables (such as past education and attitude to system use) and past usage (prior experience) must be considered. Users of IT must realize the full potential of the technology, they must be willing to use the technology and become effective users. Unfortunately, many IT applications are misused, underutilised or abandoned. User Participation

The relationship between user participation and information system (IS) has been significant because of its potential impact on the success of systems. User participation could be considered as “taking part” in some activity. Such participation may be direct or indirect, formal or informal, performed alone or in a group, covering varying scopes of activities during systems development and implementation. It may be mentioned that assessing a wide variety of specific behaviours, activities and assignments is more accurate, reliable and valid than measures assessing general opinions during user participation evaluation. Systems development, as a result of being marked by cost overruns, late deliveries, poor reliability and user dissatisfaction, in many cases, does not achieve the expected strategic benefits. It has been suggested that the participation of users in the design and implementation of IT promotes greater user acceptance, IT usage, system quality, organisational impact and increased user satisfaction, which could lead to increased IT implementation success. Cultures that are high in trust and mutual supportiveness foster higher levels of communication, shared identity and commitment. which enhances user participation. Greater the user participation in the project, the greater will be the establishment of trust in the success of the project because the users will be able to identify loopholes in the project before final implementation and will also feel committed to make it work. This also generates confidence in the users that the IT system is reliable and encourages users to take risks. User participation facilitates organisational learning by bringing together all dispersed knowledge from the various units within the organisation to one spot where employees can access information, learn from one another and benefit from new knowledge developed by other units. This provides opportunities for mutual learning and interunit cooperation that stimulate the creation of new knowledge and, at the same time, contribute to organisational units’ abilities to innovate. Perceived Ease of Use

Perceived ease of use has been an established factor influencing user acceptance and usage behavior of information technologies. It describes the individual’s perception of how easy the innovation is to learn and use. This includes support, complexity and change. It has been observed that six variables contribute significantly to how users perceive the ease of use of specific IT systems over time in an actual corporate setting. These variables include computer self-efficacy, facilitating conditions, intrinsic motivation / computer playfulness, emotion / level of computer anxiety, objective usability and perceived enjoyment. Self-efficacy has a strong direct effect on perceived ease of use, but only an indirect effect on perceived usefulness through perceived ease of use. Another factor, past usage (prior experience), also apparently influences the ease of use of the system, and this is a key factor in determining future usage.

112

Perceived Usefulness

Perceived usefulness describes the perceptions of the individual regarding the innovation and has been found to influence an individual’s adoption behaviors. Perceived usefulness can also be defined as “the degree to which a person believes that using a particular system would enhance his or her performance.” It is an example of extrinsic motivation, which is found to play a greater role in an individual’s behavior. The most important consumer attitudes underlying perceived usefulness of and willingness to use IT are expectations of accuracy, security, network speed, user-friendliness, user participation and convenience. User satisfaction, in turn, is influenced also by the user’s confirmation of expectation from prior IT use and perceived usefulness, and this is influenced by the user’s confirmation level.

Business Values of Information System

Adoption Diffusion

The process of information technology adoption and use is critical to deriving the benefits of information technology. Understanding how users form perceptions of an IT innovation would help designers, implementers and users in their evaluation, selection, implementation and on-going use of IT. The diffusion and infusion of IT, however, is a complex process that is influenced by numerous factors such as perceived characteristics of the innovation, subjective norms, stages of adoption, user competence, and implementation processes and organisational factors. Each factor has a direct effect on IT diffusion. Other findings suggest that migration costs, early of adoption, top management support and organisational size are positively associated with diffusion. However, advocacy by middle management is seen to have no positive effect on the success of implementation, but rather, having the right organisational and individual incentives could cause a widespread adoption. It has been observed that what limits the speed of usage is the lack of information available about the new technology, how to use it and what it does. Corporate Culture Classification

The corporate culture classification has been carried out in different manners. Two type of classification is being discussed here. A)

Corporate Tribes Model of Organisational Culture

This is one of the most popular and influential typologies for overall culture. This classification suggests that corporate culture can be understood and managed by identifying four different “tribes”: Tough-Guy/Macho, Work Hard/Play Hard, BetYour-Company, and Process. The degree of risk associated with company activities and the speed of feedback from the environment are the determining factors as to which quadrant best describes the overall culture of an organisation. Bet-Your-Company organisations operate in a high risk/slow feedback environment typified by the phrase “Play it Safe”. Typical industries include oil, drugs, aerospace, and public utilities. Large capital investments are usually required and the results from those investments are not usually known for a long time. A clear example would be NASA’s development of the space shuttle. The ritual of this culture is the business meeting. Important issues get full discussion. Decision-making is top-down once all the inputs are in. Actions are measured and deliberate. Once the importance of the IS plan is evident, specific decisions are made by top management and the plan starts becoming a reality. The decision makers have a great deal of character and self-confidence, which should enhance good followthrough on decisions. Also people in this culture become highly dependent on one another (they never “burn any bridges”). This implies better than average co-operation and communication between departments during the implementation effort. 113

Management Systems

Tough-Guy / Macho organisations have a high risk / quick feedback environment typified by the phrase “Find a mountain and climb it”. Typical industries include advertising, entertainment, and construction. Large capital outlays are usually required up front and the results (feedback) are usually known rather quickly. "Go for it all" decisions would fit the Tough-Guy/Macho representation. The immediate feedback of this culture fosters a short-term perspective. The youth of many people typically in this type of culture does not support a strong planning orientation. These factors lead to difficulty in implementing an IS plan. Speed, not endurance is often the focus. Not taking an action, however, is as important as taking one. There is also extremely strong internal competition which breeds individualism and weak communication, another challenge for successful implementation of the IS plan. Work Hard/Play Hard firms operate in a low risk/quick feedback environment and can be described by the phrase “Find a need and fill it”. Typical industries include retail and sales organisations. It is usually not very expensive to have a salesman make a particular sales call (low risk), but the feedback is rather immediate (quick feedback). This is an action-oriented culture. Amount is more important than quality (e.g. sales). Listing the number of benefits of an IS plan will foster more commitment than giving details on a few benefits. Immediate benefits must be highlighted whenever possible. Success comes from persistence. Process organisations operate in a low risk/slow feedback environment typified by the phrase "Be perfect". Typical industries include banking, insurance, and government departments. The process culture is exemplified by accounting departments and large, bureaucratic organisations where employees frequently focus on how they do something rather than on what they do. Benefits and projected results of the IS plan must be clearly stated. Policies and procedures are critical to a successful IS plan in a process culture. Everything must be put into a memo and/or documented. Job titles play an important role in process culture, so as new responsibilities are created or delegated, careful consideration should be given to job title and perceived status. B)

Marketing and Production-oriented Corporate Cultures

In model we define two corporate cultures, marketing and production. Marketing cultures include a market orientation where organisations develop and maintain a viable fit between the organisations’ objectives, skills and resources to the changing market opportunities. In effect, market-oriented organisations design their products and service offerings to meet customer needs with a profit. Business success depends on effective analysis of marketing opportunities, researching and selecting target markets, designing marketing strategies, planning marketing programs and organizing, implementing and controlling the marketing effort. Corporate culture is “the single most important determinant of a company’s ability to adapt to market forces.” The production-oriented businesses on the other hand, concentrate on achieving high production efficiency, low costs and mass distribution. They operate on the assumption that consumers prefer products that are widely available and inexpensive. Success is based on technological efficiency through cost cutting. Customer-oriented culture serves to make organisations more responsive to customer needs, whereas a competitor-oriented organisation works to perform well relative to the competition instead of profit maximisation or market share.

114

Production Orientation Culture

Production orientation, even though one of the oldest concepts in business, is still evident in high capital intensive industries and where demand exceeds supply. It is especially useful when consumers favour products that are available and highly affordable. In such circumstances, businesses can focus on improving production and distribution efficiencies. Manufacturing industries elected to manufacture goods based on their ability to be produced stressing standardisation and specialisation. The challenge becomes lies in finding ways to promote the products to potential purchasers in such a way as to create a perceived need for the good in the minds of potential buyers. Today, the advertising industry still finds itself constantly battling social critics who suggest that advertising, especially as practised in several countries, creates false needs, resulting in society’s unnecessary expenditures for products or services. That are not needed.

Business Values of Information System

Today, even the “best” firms sometimes backslide into a production orientation because in today’s highly competitive markets it is often difficult to keep up with changing customer needs, beat aggressive competitors to the punch, find the right focus that matches the firm’s objectives and resources to market opportunities and offer customers superior value. Market Orientation Culture

The dynamic nature of the marketplace needs requires a continuous tracking and responsiveness of these needs with superior value in a consistent manner at a profit. A market-oriented organisation generates market intelligence, disseminates the intelligence across departments and provides the appropriate response to the needs of the market at a profit. The strategy is to survey markets to identify unfulfilled needs and then to produce products that satisfy those unmet needs. It is believed that if a product or service sufficiently satisfies consumers, the product or service will basically sell itself because people with the need will seek it for fulfillment. To be effective, more resources are required to focus on what potential consumers want and then translate product traits, packaging characteristics, price levels or availability of products to the consumers. Though market orientation has been posited to lead to greater customer satisfaction and organisational commitment of employees, arguments have been advanced to the effect that a market orientation may have a strong or weak effect on business performance. This depends on the environmental conditions such as market turbulence and competitive intensity. For an organisation to be considered market oriented, it must possess three behavioural components - customer orientation, competitor orientation and inter-functional coordination- and two decision criteria: long-term focus and a profit objective. Perceived Effectiveness of IT Adoption

Perceived effectiveness of IT adoption is the extent to which individuals believe that the adoption of IT has been successful. Despite remarkable advances in information technology, many IT projects still fall short of performance expectations. A growing share of these implementation failures is caused by non-technical factors. Technology implementation success could be improved with active top management support, clear implementation goals and user participation and training. Other success factors include a good understanding of the intended end-users, their tasks and the interdependencies between the two, together with the appropriate business strategy. This should lead to adding value to the firm and positive influences on user behaviour. Unfortunately, IT success can sometimes be elusive. An effective IT application is expected to improve performance, but if poorly planned, developed or implemented without due recognition of the need to increase human resource effectiveness, it can breed disaster and retard individual and/or group performance. 115

Management Systems

IT success correlates with the perceived performance and importance of these factors in each firm. Though different firms have different levels of appreciation of importance of performance factors, their overall attitude toward IT is strongly influenced by how well those factors are handled. The firms that concentrate their resources in the most important areas will achieve greater success than those that spread their resources too thinly. Performance factors include: 1) functioning of existing transaction/reporting systems, 2) linkage to strategic processes of the firm, 3) the amount and quality of user participation, 4) the responsiveness to new systems needs, 5) the ability to respond to end-user computing needs, 6) IS staff quality, and 7) the reliability of services. Other factors include identity, significance, autonomy and feedback.

4.7 DECISION MANAGEMENT WITH INFORMATION SYSTEMS Decision-making is the cognitive process of selecting a course of action from among multiple alternatives. Every decision-making process produces a final choice. It can be an action or an opinion. It begins when we need to do something but we do not know what. Therefore decision-making is a reasoning process, which can be rational or irrational, and can be based on explicit assumptions or tacit assumptions. Common examples include shopping, deciding what to eat, and deciding whom or what to vote for in an election or referendum.

Decision-making is said to be a psychological construct. This means that although we can never “see” a decision, we can infer from observable behavior that a decision has been made. Therefore, we conclude that a psychological event that we call “decision making” has occurred. It is a construction that imputes commitment to action. That is, based on observable actions, we assume that people have made a commitment to effect the action. Structured rational decision-making is an important part of all science-based professions, where specialists apply their knowledge in a given area to making informed decisions. For example, medical decision-making often involves making a diagnosis and selecting an appropriate treatment. Some research using naturalistic methods shows, however, that in situations with higher time pressure, higher stakes, or increased ambiguities, experts use intuitive decision making rather than structured approaches, following a recognition primed decision approach to fit a set of indicators into the expert’s experience and immediately arrive at a satisfactory course of action without weighing alternatives. Information fuels the new economy and plays an essential role in developing and maintaining a sustainable competitive advantage. The demands on a business today increased global competition, lower barriers to entry, lower profit margins - are creating an ever-increasing need for access to data. The ability to get the right information to the right people at the right time is, therefore, more important than ever; however, the sheer volume of available data makes such a proposition more challenging than ever. Organisations that are the most successful at collecting, evaluating and applying information are consistently the leaders in their respective industries. The ability to act faster and more effectively than the competition can be the defining advantage in today’s marketplace and the means for successfully managing customer relationships in the long run. Managers and executives are judged, hired and fired by their performance against a variety of business goals and challenges, but they are made primarily in two ways: by the skills they possess in managing people and by the quality of their decisions. 116

Due to the large number of considerations involved in many decisions, decision support systems have been developed to assist decision makers in considering the implications of various courses of action. They can help reduce the risk of human errors. The systems, which try to realise some human/cognitive decision-making functions, are called Intelligent Decision Support Systems (IDSS).

Business Values of Information System

Decision making style

According to behaviouralists the decision making process depends to a significant degree on cognitive style, which can be divided in four bi-polar dimensions. The terminal points on these dimensions are: thinking and feeling; extroversion and introversion; judgement and perception; and sensing and intuition. A personâ&#x20AC;&#x2122;s decision-making style is based largely on how they score on these four dimensions. For example, someone who scored near the thinking, extroversion, sensing, and judgement ends of the dimensions would tend to have a logical, analytical, objective, critical, and empirical decision making style. Cognitive and personal biases in decision-making

It is generally agreed that biases can creep into our decision making processes, calling into question the correctness of a decision. Below is a list of some of the more common cognitive biases. Selective search for evidence: We tend to be willing to gather facts that support certain conclusions but disregard other facts that support different conclusions. Premature termination of search for evidence: We tend to accept the first alternative that looks like it might work. Conservatism and inertia: Unwillingness to change thought patterns that we have used in the past in the face of new circumstances. Experiential limitations: Unwillingness or inability to look beyond the scope of our past experiences; rejection of the unfamiliar. Selective perception: We actively screen-out information that we do not think is salient. Wishful thinking or optimism: We tend to want to see things in a positive light and this can distort our perception and thinking. Choice-supportive bias: occurs when we distort our memories of chosen and rejected options to make the chosen options seem relatively more attractive. Recency: We tend to place more attention on more recent information and either ignore or forget more distant information. Repetition bias: A willingness to believe what we have been told most often and by the greatest number different sources. Anchoring and adjustment: Decisions are unduly influenced by initial information that shapes our view of subsequent information. Groupthink: Peer pressure to conform to the opinions held by the group. Source credibility bias: We reject something if we have a bias against the person, organisation, or group to which the person belongs: we are inclined to accept a statement by someone we like. 117

Management Systems

Incremental decision-making and escalating commitment: We look at a decision as a small step in a process and this tends to perpetuate a series of similar decisions. This can be contrasted with zero-based decision-making. Inconsistency: The unwillingness to apply the same decision criteria in similar situations. Attribution asymmetry: We tend to attribute our success to our abilities and talents, but we attribute our failures to bad luck and external factors. We attribute otherâ&#x20AC;&#x2122;s success to good luck, and their failures to their mistakes. Role fulfillment: We conform to the decision-making expectations that others have of someone in our position. Underestimating uncertainty and the illusion of control: We tend to underestimate future uncertainty because we tend to believe we have more control over events than we really do. We believe we have control to minimize potential problems in our decisions. Faulty generalizations: In order to simplify an extremely complex world, we tend to group things and people. These simplifying generalizations can bias decision-making processes. Ascription of causality: We tend to ascribe causation even when the evidence only suggests correlation. Just because birds fly to the equatorial regions when the trees shed their leaves, does not mean that the birds migrate because the trees shed their leaves. Decision making in groups

Decision-making in groups is sometimes examined separately as process and outcome. Process refers to the interactions among individuals that lead to the choice of a particular course of action. An outcome is the consequence of that choice. Separating process and outcome is convenient because it helps explain that a good decision making process does not guarantee a good outcome, and that a good outcome does not presuppose a good process. Thus, for example, managers interested in good decisionmaking are encouraged to put good decision-making processes in place. Although these good decision making processes do not guarantee good outcomes, they can tip the balance of chance in favour of good outcomes. A critical aspect for decision-making groups is the ability to converge on a choice. Politics is one approach to making decisions in groups. This process revolves around the relative power or ability to influence individuals in the group. Some relevant ideas include coalitions among participants as well as influence and persuasion. The use of politics is often judged negatively, but it is a useful way to approach problems when preferences among actors are in conflict, when dependencies exist that cannot be avoided, when there are no super-ordinate authorities, and when the technical or scientific merit of the options is ambiguous. In addition to the different processes involved in making decisions, groups can also have different decision rules. A decision rule is the approach used by a group to mark the choice that is made. â&#x20AC;˘

Unanimity requires everyone to agree on a given course of action, and thus imposes a high bar for action. Juries in criminal trials commonly use unanimity.

•

Majority requires support from more than 50% of the members of the group. Thus, the bar for action is lower than with unanimity and a group of “losers” is implicit to this rule.

•

Consensus decision-making tries to avoid “winners” and “losers”. Consensus requires that a majority approve a given course of action, but that the minority agrees to go along with the course of action. In other words, if the minority opposes the course of action, consensus requires that the course of action be modified to remove objectionable features. •

Business Values of Information System

Sub-committee involves assigning responsibility for evaluation of a decision to a sub-set of a larger group, which then comes back to the larger group with recommendations for action. Using a sub-committee is more common in larger governance groups, such as a legislature. Sometimes a sub-committee includes those individuals most affected by a decision, although at other times it is useful for the larger group to have a sub-committee that involves more neutral participants.

Less desirable group decision rules are: •

Plurality, where the largest block in a group decides, even if it falls short of a majority.

•

Dictatorship, where one individual determines the course of action.

Plurality and dictatorship are less desirable as decision rules because they do not require the involvement of the broader group to determine a choice. Thus, they do not engender commitment to the course of action chosen. An absence of commitment from individuals in the group can be problematic during the implementation phase of a decision. There are no perfect decision making rules. Depending on how the rules are implemented in practice and the situation, all of these can lead to situations where either no decision is made, or to situations where decisions made are inconsistent with one another over time. Principles

The ethical principles of decision making vary considerably. Some common choices of principles and the methods which seem to match them include: •

The most powerful person/group decides ο Method: dictatorship or oligarchy

•

Everyone participates in a certain class of meta-decisions ο Method: parliamentary democracy

•

Everyone participates in every decision ο Direct democracy, consensus decision making

There are many grades of decision-making, which have an element of participation. A common example is that of institutions making decisions, which affect those they are charged to provide for. In such cases an understanding of what participation, is crucial to understand the process and the power structures at play. Decision making in business and management

In general, business and management systems should be set up to allow decision making at the lowest possible level. Several decision-making models for business include:

119

Management Systems

•

Analytic Hierarchy Process — procedure for multi-level goal hierarchy

•

Buyer decision processes — transaction before, during, and after a purchase

•

Complex systems — common behavioural and structural features that can be modeled.

•

Corporate finance: ο The investment decision ο The financing decision ο The dividend decision ο Working capital management decisions.

•

Cost-benefit analysis — process of weighing the total expected costs vs. the total expected benefits.

•

Decision trees ο Program Evaluation and Review Technique (PERT) ο Critical path analysis ο Critical chain analysis.

•

Force field analysis — analysing forces that either drive or hinder movement toward a goal.

•

Grid Analysis — analysis done by comparing the weighted averages of ranked criteria to options. A way of comparing both objective and subjective data.

•

Linear programming — optimisation problems in which the objective function and the constraints are all linear.

•

Min-max criterion.

•

Model (economics) — theoretical construct of economic processes of variables and their relationships.

•

Monte Carlo method — class of computational algorithms for simulating systems

•

Morphological analysis — all possible solutions to a multi-dimensional problem complex

•

Optimisation ο Constrained optimisation

•

Paired Comparison Analysis — paired choice analysis

•

Pareto Analysis — selection of a limited number of tasks that produce significant overall effect.

•

Scenario analysis — process of analysing possible future events

•

Six Thinking Hats — symbolic process for parallel thinking

•

Strategic planning process — applying the objectives, SWOTs, strategies, programs process.

•

Ubiquitous command and control is a concept for dynamic decision making based on “agreement between an individual and the world”, and “agreements between individuals”.

Making profitable business decisions faster and with greater agility is both a challenge and a goal for most organisations. But many companies still rely on manual decisionmaking processes that often prohibit consistency and efficiency. In some cases, they are completely unaware of valuable opportunities for cost-cutting or driving revenue. And it’s not because they don’t have the right data – it’s because they don’t know how to leverage and maximize it. 120

Over the last several years, more sophisticated business intelligence technology has helped companies improve their data analysis and reporting capabilities. It has also extended data analysis responsibilities to more end-users within the organisation (we’ve all heard the phrase BI for the casual user’). These are remarkable achievements. But forward-thinking companies will need to move from just managing data properly to capitalising on it. A number of new trends and best practices can help companies learn more from their data so they can make better business decisions, automatically.

Business Values of Information System

Research in Psychology and decision sciences has challenged the assumption that people apply rational principles in making decisions that work to optimise expected results. This descriptive, empirical research has catalogued many of the biases that enter into decision-making. Managers often seek to mitigate uncertainty by any means before committing to a decision. Managers make judgements by making adjustments from some initial value, even if that initial value is based on totally random information. Decision-making processes need to be improved, but which processes, are the best candidates for improvement? Strategic vs. Operational Decision Making

There are two types of decisions — operational and strategic. Strategic decisions have broad organisational scope but are infrequent, while operational decisions have more restricted scope but repeat frequently. IDC research shows that capturing and automating decision-making processes for repeatable, operational decisions are making progress. Here are some examples of operational decisions: •

Do we extend credit to this customer?

•

Are these transactions evidence of fraud?

•

How can we reroute this shipment to meet the promised delivery date?

•

What book do we recommend to this customer?

•

Should this supplier be on the approved list?

By contrast, here are examples of strategic decisions: •

Do we acquire company X or company Y?

•

Do we target retail or energy companies as an added vertical?

•

Is it time to discontinue a product line or to launch a new one?

Strategic decisions are important. However, because they are infrequent, there is little opportunity to apply lessons learned on an ongoing basis and to provide software-based automation to support such a process. That is not the case with operational decisions which are repeatable. Here are examples of operational decision-making initiatives across a variety of industries: National Bank: Customer segment managers (formerly managers for individual products) meet every Monday, armed with the output of buyer behaviour models, to decide which products to offer to each segment.

Manufacturer of Electronic Devices and Components: In the R&D division, best practices are being captured to determine which lines of research to continue and which to halt - resulting in significant savings in R&D expenses. Hewlett-Packard: An analysis of PC warranty claims provides an early warning of product defects, enabling remedial actions in the manufacturing process and proactive communications to customers. Banco Espirito Santo: This Company deployed an early warning system to detect actions leading to customer attrition. By using predictive modeling software, they were able to improve “at-risk” banking customer retention by 50 per cent. Decision Support Systems Decision support systems are a class of computerized information systems or knowledge based systems that support decision-making activities. The concept of a decision support system (DSS) is extremely broad. A DSS can take many different forms and the term can be used in many different ways.

On the one hand, a DSS is broadly defined as “a computer-based system that aids the process of decision making.” In a more precise way, it has been defined as “an interactive, flexible, and adaptable computer-based information system, especially developed for supporting the solution of a non-structured management problem for improved decision making. It utilises data, provides an easy-to-use interface, and allows for the decision maker’s own insights.” Other definitions, which fill the gap between these two extremes, are: •

DSS couple the intellectual resources of individuals with the capabilities of the computer to improve the quality of decisions (“DSS are computer-based support for management decision makers who are dealing with semi-structured problems”).

•

DSS are “interactive computer-based systems that help decision makers utilise data and models to solve unstructured problems.”

•

The term decision support system remains a useful and inclusive term for many types of information systems that support decision making.

As of now, there is no universally accepted definition of DSS. Additionally, the specifics of it are what make it less generalised and more detailed. In addition, a DSS also is a specific Software application that helps to analyse data contained within a customer database. This approach to customers is used when deciding on target markets as well as customer habits. This may be noticed this specific example, that DSS can be used for more than just organisation. Classification of Decision Support Systems

As with the definition, there is no all-inclusive classification of DSS either. Different authors propose different classifications. At the user-level, differentiation may be passive, active, and cooperative DSS.

122

•

A passive DSS is a system that aids the process of decision-making, but that cannot bring out explicit decision suggestions or solutions.

•

An active DSS can bring out such decision suggestions or solutions.

•

A cooperative DSS allows the decision maker (or its advisor) to modify, complete, or refine the decision suggestions provided by the system, before sending them back to the system for validation. The system again improves, completes, and refines the suggestions of the decision maker and sends them back to him/her for validation. The whole process then starts again, until a consolidated solution is generated.

Business Values of Information System

At the conceptual level, differentiation may be communication-driven DSS, datadriven DSS, document-driven DSS, knowledge-driven DSS, and model-driven DSS. •

A model-driven DSS emphasizes access to and manipulation of a statistical, financial, optimisation, or simulation model. Model-driven DSS use data and parameters provided by DSS users to aid decision makers in analysing a situation, but they are not necessarily data intensive. Dicodess is an example of an open source, model-driven DSS generator.

•

A communication-driven DSS supports more than one person working on a shared task; examples include integrated tools like Microsoft's NetMeeting or Groove.

•

A data-driven DSS or data-oriented DSS emphasizes access to and manipulation of a time series of internal company data and, sometimes, external data.

•

A document-driven DSS manages, retrieves and manipulates unstructured information in a variety of electronic formats.

•

A knowledge-driven DSS provides specialised problem solving expertise stored as facts, rules, procedures, or in similar structures.

At the system level, differentiation may be enterprise-wide DSS and desktop DSS. •

Enterprise-wide DSS are linked to large data warehouses and serve many managers in a company.

•

Desktop, single-user DSS are small systems that reside on an individual manager's PC.

When classifying DSS, it can be viewed as very broad or very narrow. Since it is difficult to classify DSS into only one classification, the taxonomy cannot exactly be pinpointed. However, if it is necessary, a DSS is certainly classified into precise, scientific organisational software that not only contributes, but also performs decision-making steps in order to ease the pressure for its users. The fact is in a few words, DSS is organisational decision-making software. Architectures

Once again, different authors identify different components in a DSS. Three fundamental components of DSS can be categorized as: (a) the database management system (DBMS), (b) the model-base management system (MBMS), and (c) the dialog generation and management system (DGMS). These three components can be described in more detail: the Data Management Component stores information (which can be further subdivided into that derived from an organisation’s traditional data repositories, from external sources such as the Internet, or from the personal insights and experiences of individual users); the Model Management Component handles representations of events, facts, or situations (using various kinds of models, two examples being optimisation models and goal-seeking models); and the User Interface 123

Management Systems

Management Component is of course the component that allows a user to interact with the system. Academics and practitioners have discussed building DSS in terms of four major components: (a) the user interface, (b) the database, (c) the model and analytical tools, and (d) the DSS architecture and network. HĂ¤ttenschwiler (1999) identifies five components of DSS: (a) users with different roles or functions in the decision making process (decision maker, advisors, domain experts, system experts, data collectors), (b) a specific and definable decision context, (c) a target system describing the majority of the preferences, (d) a knowledge base made of external data sources, knowledge databases, working databases, data warehouses and meta-databases, mathematical models and methods, procedures, inference and search engines, administrative programs, and reporting systems, and (e) a working environment for the preparation, analysis, and documentation of decision alternatives. Marakas (1999) proposes a generalised architecture made of five distinct parts: (a) the data management system, (b) the model management system, (c) the knowledge engine, (d) the user interface, and (e) the user(s). There are several ways to classify DSS applications. Not every DSS fits neatly into one category, but a mix of two or more architecture in one. The six frameworks in which DSS can be classified are: Text-oriented DSS, Database-oriented DSS, Spreadsheet-oriented DSS, Solver-oriented DSS, Rule-oriented DSS, and Compound DSS. The support given by DSS can be separated into three distinct interrelated categories: Personal Support, Group Support and Organisational Support. Additionally, DSS can be classified in a similar way. The build up of a DSS is classified into a few characteristics. (1) Inputs: this is used so the DSS can have factors, numbers, and characteristics to analyze. (2) User knowledge and expertise: This allows the system to decide how much it is relied on, and exactly what inputs must be analysed with or without the user. (3) Outputs/Feedback: This is used so the user of the system can analyse the decisions that may be made and then potentially (4) make a decision: This decision making is done by the DSSâ&#x20AC;&#x2122;, however, it is ultimately made by the user in order to decide on which criteria it should use. Applications

As mentioned above, there are theoretical possibilities of building such systems in any knowledge domain. One of the examples is clinical decision support system for medical diagnosis. Other examples include a bank loan officer verifying the credit of a loan applicant or an engineering firm that has bids on several projects and wants to know if they can be competitive with their costs. A specific example concerns the Canadian National Railway system, which tests its equipment on a regular basis using a Decision Support System. A problem faced by any railroad is worn-out or defective rails, which can result in hundreds of derailments per year. Under a DSS, CN managed to decrease the incidence of derailments at the same time other companies were experiencing an increase. DSS has many applications that have already been spoken about. However, it can be used in any field where organisation is necessary. Additionally, a DSS can be designed to help make decisions on the stock market, or deciding which area or segment to 124

market a product toward. DSS has endless possibilities that can be used anywhere and anytime, for its decision making needs.

4.8 SUMMARY With this unit, we have completed the first block on this subject and thus rounded off our discussion on fundamentals of organisations, Management and Information Systems. We have covered what factors need be looked into for planning, evaluating and implementing information systems at organisational and management levels. In this unit our discussion must have helped you to understand business value of information systems. We have discussed, besides financial evaluation, the human angle as well as other direct and indirect costs and benefits to be kept in mind in estimating total cost of an information system. We have also completed our discussion on a very important topic i.e., decision making and how information system is providing support in this domain. In the next block we will move on to finer aspects relating to Information Systems.

iii) False

iv)True

v)False

vi) False.

2) a)

By “Now economy”, we mean a real-time enterprise – an organisation is expected to react instantaneously to changes in its business. They are expected to provide “instant gratification” to customers. Products and services are expected to be delivered by them to customers: anytime (24/7), anywhere (global reach), any form (mass customisation), and any price (dynamic pricing depending on real-time supply-demand adjustment). The organisation will need Real-time Monitoring, Reporting and Decision-making.

Four kinds of empirical studies: and their combination provide answers to the basic research questions: The kind of empirical studies are: • • • •

126

exploratory studies that yield causal hypotheses; assessment studies that establish baselines, ranges, benchmark that manipulate experiments to test hypotheses about causal influences; and observation experiments (or quasi-experiments) that disclose effects of factors on measured variables without random assignment of treatments.

There are two types of benefits (i) Tangible and (ii) Intangible. Four elements each of the cost and of the two types of benefits are as indicated below:

Costs Hardware Software Services Manpower

Benefits (Intangible) Improved operations Better asset utilisation Better organisational planning Better customer satisfaction

Business Values of Information System

Benefits (Tangible) Increased Productivity Reduced manpower Lower vendor services cost Lower Clerical overheads

Real Option Pricing Model is considered for the strategic decision with respect to whether the project needs to be taken up now or later and when it will be more beneficial. Real options model has six categories based upon the type of flexibility provided. The six categories are: the option to defer; the option for staged investments; the option to change scale; the option to abandon; the option to switch; and the option to grow.

The Indirect costs which need to be considered for total cost of ownership (TCO) are: • • • • • • •

Operations management, Systems management, Maintenance of hardware and software components, Ongoing license fees, Upgrade costs, User support, Environmental factors affecting the system's external requirements for proper operation, such as air conditioning, power supply, housing, and floor space.

The established factors of corporate culture having deep impact on the Information system are: • • • • •

Extent of Application User Participation Perceived Ease of Use Perceived Usefulness Adoption Diffusion.

1.0 INTRODUCTION A process can be used gainfully only when it is understood well, in this unit you will be made familiar with the objectives, steps, methods and gains of the portfolio management. This unit takes you through the first, and ultimately the most empowering, phase in portfolio management implementation. You will learn why establishing a portfolio management team with well-defined roles and responsibilities is critical. You will also gain an understanding of why it is crucial to carefully define the portfolio management process and choreograph its interrelationship with the budgeting process, the project proposal process, and other existing business processes. You will learn how to apply these concepts in an operational organisation. This unit provides an understanding of the value of a portfolio management solution and offers insight into the types of functionality that must be inherent in such an application. The world is getting increasingly interconnected and information is now centralised and we see businesses being pushed to the edge of the networks. In order to race to the market, security, and controls over such critical information tend to get overlooked. This translates into issues related to confidentiality, integrity and availability of information — key controls in the information economy. Effective information risk management therefore assumes critical importance. Not only risk needs to be minimized but there is strong need for readiness for the disaster recovery. In this unit you will gain an insight for meeting these challenges.

1.1 OBJECTIVES After going through this unit, you should be able to: • • • • • • •

define the portfolio management; explain the portfolio management methods and implement it; define the risk management and will be able to plan to alleviate it; explain disasters management; appreciate the challenges and issues of the portfolio management; select the tools of the portfolio management suiting the requirement, and Appreciate the emerging technologies.

1.2 WHAT IS PORTFOLIO MANAGEMENT Portfolio Management is a process which facilitates determining the right (project) investments mix, i.e., deploying limited resources to maximize business performance, which is a key management challenge. Most capital investment activities take the form of projects that need to be managed as part of a portfolio. Project portfolio management entails balancing resources, business needs, business risks and changing parameters, while at the same time maximizing the return on (project) investment. Portfolio Management was originally coined in the financial and investment community, and the term was used for the process of managing the assets of a mutual fund; including choosing and monitoring appropriate investments and allocating funds accordingly. The adoption of the terminology into other industries such as real estate resulted in a modification of the term to reflect industry specific purposes. Similarly, within the technology sector, the term now applies to a set of projects or programs grouped collectively and monitored. We can define portfolio management as the expression of the alignment of the corporate and IT strategic plans, viewing the portfolio as a suite of complementary investments that collectively provide the best possible allocation of resources to meet the business needs of the corporation. Portfolio Management (PM) applications integrate all project-related informations within a single, web-based enterprise solution. Organisations use PM solutions to better align and manage their projects, people, and partners so that they can achieve greater return on their portfolio of investments. Basically, Portfolio Management is a discipline used to ensure that a correct mix of investment activity is initiated, grouped, funded and managed. Technology assets are categorised as an investment portfolio allowing for: • • • • •

Investment bundling Prioritisation Evaluation Decision insight and support Balance between timing, current needs, and future requirements

Considering the complexities, the problem of managing the technology portfolio is broken into set of smaller problems to facilitate analysis. Among the issues to be considered when discussing the technology portfolio are: • • • • • •

Technology / business alignment Investment balance Resource management Negotiation between competing projects or goals Risk mitigation and management Technology performance and reporting

Considered as part of the whole, each contributes to the overall portfolio. Considered independently, each is both a manageable problem and a powerful tool. Portfolio Management Objectives allow the organisation to be focused, fast, and agile. Achieving these high level objectives necessitates a variety of inter-related steps. These include the following: • 6

Grouping: Synergies between technology spending plans with business strategy;

• • • •

Investment Focus: Viewing expenditures (human, asset, capital) as investments. This also includes a process to track performance; Governance: Process for making IT investment decisions; Cost Control: Understanding the main drivers of IT costs for restraint purposes, and Efficiency: Use of financial resources efficiently, leveraging wherever possible.

Portfolio Management and IT Applications

Various methods are used to create and balance the portfolio, ranging from highly strategic to tactical: Financial portfolio analysis: Balance and risk mitigation is achieved by spreading investments over a number of different initiatives. Projects are balanced across a number of categories that can include strategic or business objectives, compliance or required maintenance and research and development. Depending on the organisation’s objectives, this allows steering committees to incur the least risk and take advantage of market dynamics. Top down / bottom up: Companies either apply the big picture of top-down thinking that looks at growth, or how dual projects or business unit objectives provide benefits in bottom-up planning. Both exercises are popular with immature project organisations. However, if conducted separately in a vacuum, it provides a restricted view of the inter-relationships of projects to the organisation. A combined top down/bottom-up approach is the desired solution for such an endeavor. A variety of Portfolio Management Benefits are possible for the organisation successfully executing a PM initiative. Chief among these is the expression of value in business terms. Other key benefits include: • • • • • •

Insight into schedule / budget variance Return on investment calculations Increased resource utilisation and reduced headcount Extrapolating financial benefits of a project Project interventions and results Discontinued projects or corrective measures as necessary

Ultimately, a portfolio management for technology organisations will offer IT management and a sense of symmetry with business objectives; like, a project selection approach based on hard data and the metrics, costs, budgets, and other objective criterias. It should be noted, however, that as long as IT continues to plan at the individual initiative level, the tactical and reactive nature of most IT organisations would remain. Effective portfolio planning and management bridges the gap towards flexibility and risk mitigation. There are five primary value addition propositions that can be achieved with the implementation of a PM solution. These include: •

Align Business Strategy and Execution: Integrate executive guidance (portfolio and financial plans), line sponsorship and project-level execution so that you do the right work;

•

Plan and Execute effectively and efficiently: Standardise workflows and automate business processes so that you can do the right work faster; 7

Information Systems

•

Leverage Resources (People, Partners, Money and Assets): Manage resources across the enterprise and around the world so that you use the right resources;

•

Make global teams more productive: Share and reuse information, work products and templates so that you do the work right, and

•

Improve visibility and control: Gain organisational transparency so that you can identify and solve problems early.

The market for Portfolio Management solutions is full of competitive offerings. It is important that PM software evaluations base evaluation criteria on value versus just features and functions. Traditional feature / function evaluation approaches can mislead an organisation to select an application that does not deliver a return on investment, or worse yet, provide a stopgap solution to only part of the problem. Portfolio Management Requirements that must be available in the offered / selected PM solution can be judged based on recognising the importance of achieving value and measurable return on investment and variety of features and functions which must be present in the PM solution. These can be broadly categorized into four functional areas: •

Budget and Financial Management;

•

Business Planning and Portfolio Management;

•

Project and Resource Management;

•

Collaboration and Knowledge Management.

The budget and financial management functionality of a PM solution should integrate with existing financial and Enterprise Resource Planning (ERP) applications to provide the organisation with real-time project-based budget and financial management capabilities. Easy access to accurate project-based financial information is mandatory so that the organisation can make better and faster business decisions and invest money for maximum return. Functionality should also be provided to automate traditionally manual processes so that resources previously wasted on redundant data entry, manual analysis of project cost estimates, actual time and expenses can be redeployed. Benefits that should be enabled by the application include the ability to: •

Align spend with projects of greatest return;

•

Utilise project-based budgets to make better decisions;

•

Manage project budgets against financial objectives, and

•

Make project budgets transparent to sponsor organisations.

Functionality required while delivering the above value and benefits include:

•

Project and Resource-driven Budget and Approval Process;

•

Budget by project, initiative and organisation;

•

Budget billable and non-billable projects;

•

Budget revenue and expense;

•

Configure budget rules;

As an example, budgeting is a relatively mature process within the majority of organisations. However, the corporate requirement to ensure alignment with changing business and economic condition necessitates a continuous re-budgeting in order to remain competitive. As a result, thousands of hours of time, effort and paper are required to keep budget data current and aligned. In the ‘bottom-up’ and ‘top-down’ budgeting method, an easy way to understand look and feel can be provided. Top-down budget amounts are provided by the sponsoring organisation, and subsequently, the budget layers are built up project-by-project, program-by-program. It is vital to note that budgeting is conducted at the work level, not the cost-center level, thereby ensuring accuracy. The system also feeds the corporate budgeting system, thus allowing management of both the provider side and the consumer side. Another critical feature facing the financial severity is funding. This notion provides the benefit of releasing the total money associated with a project. Thus, a project with a large budget may only receive a portion of the allocated funding in the initial stages, with the balance released upon completion of defined milestones. This allows project sponsors to effectively govern the distribution of funds and re-allocate funds midstream if necessary. Funds can be allocated in stages and even from other projects. The business planning and portfolio management aspects of a PM application should enable the organisation to define, evaluate, and monitor their portfolio of projects for maximum return on investment. Organisations should be able to use this functionality to establish the definition, scope, risks and expected return for their portfolio of projects. In addition, they should be able to model new and existing projects to determine the optimum portfolio mix that maximizes their investment return.

Information Systems

Once portfolios are defined and prioritised against corporate objectives, organisations should be able to monitor project portfolios through customisable views. With realtime access into performed project work and planned project resources, organisations should be able to use the PM application to ensure their portfolio of projects, remains aligned with corporate objectives, identify and resolve project risks and resource bottlenecks, and proactively make decisions to maximise return on investment and minimize time to market. Benefits that should be enabled by the application include the ability to: •

Select the most important projects;

•

Establish the right definitions of project success;

•

Monitor project performance against objectives;

•

Re-align projects when market conditions change, and

•

Cancel low priority and failing projects quickly.

Functionality required delivering the above value and benefits include: •

“What if” scenario modeling / Sensitivity Analysis: o Compare portfolio plans against current operating plans o Analyse the impact of new projects on the portfolio o Drag and drop schedules o Create multiple versions of project portfolio to compare against supply

The Role of Services is critical in the successful implementation of a PM solution. Issues including integration with ERP applications, backend databases, as well as the skill and expertise required to deliver the above, are crucial aspects of a PM vendor’s strength. Each step in the implementation process must be designed to deliver incremental benefits, even those before the sales commitment. This allows for the enterprise to achieve more value sooner, however a traditional “big bang” that takes longer to implement, reduces total value, and has a higher risk. The software must provide tools to enable services team to develop and provide detailed work plans, monitoring progress via weekly status reports, maintaining logs of issues and risks, and ensuring oversight of bug and enhancement requests. As part of the transition management strategy, the team should conduct extensive executive workshops and interviews, executes upon a comprehensive communications plan, and delivers upon a value assessment. 12

Another key ingredient in any successful software implementation is end user acceptance and usage. In a nutshell, Transition Management is the process of deliberately influencing the human, organisational and workflow aspects associated with a change or introduction of technology to achieve the desired results. This notion must be integrated into the overall implementation process. By ensuring that the enterprise quickly and effectively adopts its new technology, productivity as an organisation and more competitiveness in their industry is within reach.

Portfolio Management and IT Applications

Enterprises should look to realize the following benefits from a transition management effort: •

Broadened ownership of implementation success across organisations by creating goal alignment through early, end-user involvement;

•

Minimized organisational barriers to success by identifying and mitigating organisational issues that will either lengthen the implementation or jeoparadize its success;

•

Improved organisational knowledge and skills for the new environment, as well as increased organisational effectiveness during implementation;

•

Accelerated attainment of projected benefits by focusing on postimplementation issues like user acceptance, productivity, and human performance support, and

•

Pass on ownership feeling to the end-user at the early stage of the project.

1.3 DESIGN AND IMPLEMENTATION OF PORTFOLIO MANAGEMENT Before we get into the Design and Implementation of Portfolio Management, let us look once again at the benefits expected from the implementation of the Portfolio Management. These are: • • • • •

Maximize value of IT investments while minimizing the risk; Improve communication and alignment between Information System group and business leaders; Encourage business leaders to think “team,” not “me,” and to take responsibility for projects; Allow planners to schedule resources more efficiently; Reduce the number of redundant projects.

There’s no single right way to do IT portfolio management. Vendors, consulting companies and academics offer many models, and often companies develop their own methodologies. Off-the-shelf software is available from a variety of vendors but there are plenty of hurdles to doing it well. There are, however, best practices and key logical steps that can be learned from the organisations which have integrated portfolio management into the fabric of IT management. Here are the key steps in creating and managing the IT investment portfolio based on the experience of gained from several companies.

Step 1 Assemble: Project Inventory Portfolio management begins with gathering a detailed inventory of all the projects in the company, ideally in a single database, including name, length, estimated cost, 13

Information Systems

business objective, ROI and business benefits. There are MNC’s who maintain a global database of all its IT projects using software from established IT vendors. In addition to project plan information, all company users—which may be in thousands from various regions and countries—will have to add weekly updates on how much time they spend working on projects. This is used to gather information on resources. Creating a project portfolio inventory can be painstaking but is well worth the effort. For many companies, it may be their first holistic view of the entire IT portfolio and any redundancies. A good inventory is the foundation for developing the projects that best meet strategic objectives.

Step 2 Evaluate: Identify Projects that Match Strategic Objectives A logical starting point creates a product strategy — markets, customers, products, strategy approach, competitive emphasis, etc The next step involves establishing a portfolio process. The heads of business units, in conjunction with the senior IT leaders in each of those units, compile a list of projects during the annual planning cycle and support them with good business cases that show estimated costs, ROI, business benefit and risk assessment. The leadership team vets those projects and shifts out the ones with questionable business value. Next, a senior-level IT steering committee made up of business unit heads, IT leaders and perhaps other senior executives meets to review the project proposals; a good governance structure is central to make this work. Portfolio management without governance is an empty concept conversely; putting portfolio management in place can force companies with weak governance structures to improve them. One of the core criterion for which projects get funded is how closely a project meets a company’s strategic objectives for the upcoming year. For this purpose an executive leadership team, which may include the CEO, may create strategic initiatives, such as CRM or organisational excellence. The IT governance council, made up of business leaders and senior IT leaders, then may evaluate projects based on how well they map against those initiatives. It is worthwhile to assess risk from a technology point of view, a change-management point of view, the number of people that a project will impact and whether it will involve huge reengineering. Using methodology borrowed from the product development group (modified for IS, but keeping terminology that business executives are familiar with), projects are may be placed “above the line”— those that should be funded, or “below the line”— those that shouldn’t. A project portfolio review board (comprising of senior officers / departmental heads) may further evaluate the project opportunity assessment for every proposal. A good evaluation process can help companies detect overlapping project proposals up front, cut off projects with poor business cases earlier, and strengthen alignment between IS and business executives.

Step 3 Prioritize: Score and Categorise Projects After evaluating projects, most companies will still have more than they can actually fund. The beauty of portfolio management is that ultimately, the prioritisation process will allow you to fund the projects that most closely align with your company's strategic objectives.

Next, the projects are required to be placed into portfolios—multiple portfolios may be a good idea in many companies because they allow alike projects to be pooled together.

In case of the large technology portfolio, its management team—made up of project sponsors, function managers (for example, representatives from engineering, financial services and operations, and CEO himself) and product portfolio managers (people with long-term project leadership responsibilities in areas such as services or data management)—may vet projects and come up with a list for the portfolio team to score.

Portfolio Management and IT Applications

They then prioritised them using a model that has four key tenets: a)

Identify four to seven strategies: For example, limiting technology risk and increasing the reliability of the infrastructure.

Decide on one criterion per strategy: For example, the team decided the criterion for limiting technology risk would be whether the technology had been implemented in a comparable organisation and the benefits could be translated to the company easily.

Weigh the criteria: Allocate the weight to each criteria.

Keep the scoring scale simple: Many companies use a scale of one to five. For the technology risk strategy, five might mean that it has been used in a comparable organisation and the benefits could be transferred easily; three could mean it’s hard to do because it would require changing processes; one might mean they haven’t seen it work anywhere else.

Following the scoring, the team may draw a line based on how many projects it could do with existing resources. In the case of the large technology portfolio, the line may be calculated where demand (the list of projects) meet supply (resources—in this case, the cumulative money value of available application engineers plus overhead); the line may be a little less than halfway down the list. Those projects above the line could be taken up immediately. There is no one method to categorise IT investment portfolio. One approach is to categorise it as you would do with your own financial portfolio, balancing riskier, higher reward strategic investments with safer categories, such as infrastructure. Some companies recommend a portfolio divided into three investment categories: running (keeping the lights on), growing (supporting organic growth) and transforming the business (finding new ways of doing business using technology). Those categories can then be cross-tabulated with four to five value-focused categories, such as how those investments support revenue growth, reduce costs or grow market share. In another model, based on their the previous experience, companies view their IT portfolios on multiple levels and at different stages, by visualising their investments in aggregate and placing them in four categories, with the per cent of IT expenditures apportioned across each. For example they may have 5 per cent [of the projects] in strategic areas, 15 per cent to 20 per cent in the informational category, and the remaining percentage split between the infrastructure and transaction modules, The payoffs that come from a thorough evaluation and prioritisation process is the primary reason portfolio management is so effective. Firstly communication between IS and business leaders improves, and portfolio management gives business leaders a valuable, newfound skill—the ability to understand how IT initiatives impact their companies. Secondly, business leaders think “team,” not “me,” and take responsibility for projects. One tried-and-true method for how a business leader got money for his unit’s projects was to scream louder than everyone else. Portfolio management throws that practice out the corner office window; decisions are made based on the best interests of the company.

Information Systems

Thirdly, portfolio management gives business leaders responsibility for IT projects. No longer the IT persons had to sell these IT projects to the business. For example a project for marketing, it’s the marketing executive who has to sell the project to the rest of the team. In the changed scenario, (instead of the technology people who were earlier proposing the projects) now the businesspeople propose the projects and [take responsibility] for risk profiling, ongoing operational costs and timeliness of delivery. Finally, everybody knows where the money is flowing and why, which is especially important to CEOs and CFOs who are increasingly demanding that technology investments deliver value and support strategic objectives.

Step 4 Review: Actively Manage the Portfolio A top-notch evaluation and prioritisation process is ineffectual rather quickly if the portfolio is not actively managed following approval of the project list. Doing that involves monitoring projects at frequent intervals, at least quarterly (preferably it should be monthly), the project management office is required to get financial and work progress perspective updated from project leaders. This information is required to go into a database, from where the project inventory and its status is circulated to all concerned. Some of the companies assign project status—green (good), yellow (caution) or red (help!)—and include an explanation of the key driver causing a yellow or red condition. The IT steering committee meets once a month to make decisions to continue or stop initiatives, assess funding levels and resolve resource issues. Monitoring project portfolios regularly also means projects that have run off the rails can be killed more easily. “People have an aversion to stopping projects, but the majority of projects which are canceled are done because there’s a change in company strategy—a change in priority or direction. For example, if there’s a strategy decision to focus on SAP, then it makes sense to cancel a new system that interfaces with PeopleSoft. Portfolio management is a good thing. But getting to nirvana requires a serious commitment from both the business and IS sides, as well as a whole lot of sweat equity. Here are some of the pitfalls and ways to overcome them. • •

• • • • •

Democracy is not easy: Taking power away from business leaders accustomed to calling the shots will not always go smoothly. Group decision: Business leaders who didn’t have decisions scrutinized previously now are [having] decisions decided by group consensus, people realize it does work and that group of people can make better decisions than one or two making unilateral decisions. There’s no single software that does everything: “There are really good budget packages, resource management packages and fairly good portfolio management packages, but no package that ties it all together,” Getting good information isn’t easy: Take, for example, the transparency of the cost structure. There has to be good information around all technology costs and investments In addition, database must be updated regularly, so that there continuous flow of status of each project to the concerned persons to enable them to react quickly to market changes. It’s still hard to make tough decisions on whether to undertake—or cancel—projects: as an organisation has a tendency to say, we shall figure out a way to make those work.” It’s an additional time constraint on busy executives: Good portfolio management means good IT governance means regular IT governance committee meetings. Just about every company today has its people stretched.

1.4 PORTFOLIO MANAGEMENT METHODS

Portfolio Management and IT Applications

We have gone through the implementation of portfolio management at Para 5.3 above. The basic steps for implementation are: 1) Collect / identify all ongoing and proposed projects / opportunities. 2) Out of the list compiled at a) above, identify/evaluate projects/opportunities which meet strategic requirement of the company. 3) Prioritize as per the score & categorize these projects/opportunities. 4) Review the projects/opportunities for adoption plan and monitor their implementation. Each of the above steps can be carried out by different methods. In fact Portfolio Management vendors, not only present their own variant of methods in their packages, but these packages have some minor variations in sequence of these steps also. We will be discussing some of the common methods for each of these steps. Step 1: Collect information on all projects (on-going and planned): In this step goal is to collect all relevant information on the projects like, status of the project, resources used and required for completion of the project, project schedule and the risk factor involved. Methods used for this are: •

Central repository based present day systems which collect data in formats generated (based on initial key information / data entered) by the system and stored in the data base.

•

Conventional procedures of project management, wherein data is entered for each project and stored in a common database.

Step 2: Evaluate for Strategic Compliance: A logical starting point for this step is to create a product strategy — markets, customers, products, strategy approach, competitive emphasis etc. Some companies define these strategies in terms of Key Performance Indicators (KPIs). Once strategy is defined then each identified project / opportunity is evaluated against strategy to determine if those opportunities are in line with the corporate strategic direction. In a sense, this may be the identification and initial screening of projects before more in-depth analysis is conducted. The questions asked are: What is the project? Does the project fit within the focus of the organisation and the business strategy and goals? This evaluation is done in two manners: (a) Tactical Evaluation, and (b) Financial Evaluation. a)

Tactical Evaluation •

Top-down, strategic buckets: Begin at the top with your business’s strategy and from that, the product innovation strategy for your business – its goals, and where and how to focus your new project efforts. Next, make splits in resources: ‘given your strategy, where should you spend your money?’. These splits can be by project types, product lines, markets or industry sectors, and so on. Thus, you establish strategic buckets or envelopes of resources. Then, within each bucket or envelope, list all the projects – active, on-hold and new – and rank these until you run out of resources in that bucket. The result is multiple portfolios, one portfolio per bucket. Another result is that your spending at year-end will truly reflect the strategic priorities of your business.

•

Top-down, product roadmap: Once again, begin at the top, namely with your business and product innovation strategy But here the question is: ‘given that you have selected several areas of strategic focus – markets, technologies or product types – what major initiatives must you undertake in

Information Systems

order to be successful here?’. It’s analogous to the military general asking: given that I wish to succeed in this strategic arena, what major initiatives and assaults must I undertake in order to win here? The end result is a mapping of these major initiatives along a timeline – the project roadmap. The selected projects are 100% strategically driven. •

Bottom-up: “Make good decisions on individual projects, and the portfolio will take care of itself” is a commonly accepted philosophy. That is, make sure that your project gating system is working well – that gates are accepting good projects, and killing the poor ones – and the resulting portfolio will be a solid one. Even better, to ensure strategic alignment, use a scoring model at your project reviews and gates, and include a number of strategic questions in this model. Strategic alignment is all but assured: your portfolio will indeed consist of all “on strategy” projects (although spending splits may not coincide with strategic priorities).

Financial Evaluation

It is to further define the project (if needed) and to analyze the details surrounding its utility. The utility of a project captures the usefulness of the project, its value, and is typically defined by costs, benefits, and associated risks. The questions to ask are: Why should this project be pursued? What is the usefulness and value of the project? Several things are to be considered. Establish criteria and develop a model to support decision making; Make sure accurate data is available to make decisions. Establish a process to analyze the project information; uniformly apply the methodology across the organisation. The different methods for valuation are:

•

Net Present Value (NPV): In this method for each project NPV is determined which is divided by the key or constraining resource. For example for the Project A NPV will be divided by X where X is costs still left to be spent on the project A.; that is, Portfolio Index of this project will be NPV/X. Some of the companies multiply this factor by probability (say P) of completion of the project. Then Portfolio Index will be NPV * P / X. Projects are rank-ordered according to this index until out of resources, thus maximizing the value of the portfolio (the sum of the NPVs across all projects) for a given or limited resource expenditure.

•

ECV: The Expected Commercial Value method uses decision-tree analysis, breaking the project into decision stages – e.g., Development and Commercialisation (Figure 1), define the various possible outcomes of the project along with probabilities of each occurring (for example probabilities of technical and commercial success). The resulting ECV is then divided by the constraining resource (as in the NPV method), and projects are rank-ordered according to this index in order to maximize the portfolio index. The method also approximates real options theory, and thus is appropriate for handling higher risk projects.

The project is broken into stages in decision-tree format. Outcomes, consequences and probabilities are shown in the fig. To calculate the ECV, follow the link from PV on the right to ECV on the left.

Figure 1: Calculation of expected commercial value of project

Step 3. Prioritizing and Balancing: The third major area of portfolio management is the development and selection of the project portfolio. The questions to ask are: Which projects should be selected? How does the project relate to the entire portfolio, and how can the project mix be optimized? Several things need to be considered: Establish a process that will help optimize the portfolio not just the individual projects. Establish portfolio decision meetings to make decisions. Seek Balance in Your Portfolio: Here, the goal is to achieve a desired balance of projects in terms of a number of parameters; for example, long term projects versus short ones; or high risk versus lower risk projects; and across various markets, technologies, product categories, and project types (e.g., new products, improvements, cost reductions, maintenance and fixes, and fundamental research). Pictures portray balance much better than do numbers and lists, and so the techniques used here are largely graphical in nature. These include: •

Scoring model: Decision-makers rate projects on a number of questions that distinguish superior projects, typically on 1-5 or 0-10 scales. Add up these ratings to yield a quantified project usefulness score, which must clear a minimum hurdle. This Score is a proxy for the “value of the project” but incorporates strategic, leverage and other considerations beyond just financial measures. Projects are then rank-ordered according to this score until resources run out. A typical scoring scheme is shown in Figure 2.

While this visual presentation is useful, it can’t prioritize projects. Therefore, some mix of these techniques like, bubble chat along with pie chart etc. is appropriate to support the Portfolio Management Process. This mix is often dependent upon the priority of the goals. Both bubble diagrams and pie charts, unlike the maximisation tools outlined above, are not decision-models, but rather information display: they depict the current portfolio and where the resources are going – the ‘what is’. These charts provide a useful beginning for the discussion of ‘what should be’ – how should your resources be allocated. A final check is to analyse product and technology roadmaps for project relationships. For example, if a lower priority platform project was omitted from the portfolio priority list, the subsequent higher priority projects that depend on that platform or platform technology would be impossible to execute unless that platform project were included in the portfolio priority list. Balancing It is very important that the Right Number of Projects are picked. Most companies have too many projects underway for the limited resources available. The result is pipeline gridlock: projects end up in a queue, they take too long to reach the market, and key activities – for example, doing the up-front homework – are omitted because of a lack of people and time. Thus, an over-riding goal is to ensure a balance between resources required for the active projects and resources available. Here are the ways: • Resource limits: The value maximization methods build in a resource limitation – rank your projects until out of resources. The same is true of bubble diagrams the

Information Systems

sum of the areas of the bubbles – the resources devoted to each project – should be a constant, and adding one more project to the diagram requires that another be deleted. • Resource capacity analysis: Determine your resource demand, prioritise your projects (best to worst) and add up the resources required by department for all active projects (usually expressed in person-days per month). Project management software, such as MS-Project, enables this roll-up of resource requirements. Then determine the available resources (the supply) per department – how much time people have to work on these projects. A department-by-department and month-by-month assessment usually reveals that there are too many projects; it suggests a project limit (the point beyond which projects in the prioritized list should be put on hold); and it identifies which departments are the bottlenecks. Decision Gates Process Right from the first stage, the elimination of projects which do not meet the requirements of that step are required to be eliminated. This process of removal or delaying of projects is carried out by decision gates (Figure 5). The process chain for decision-based monitoring and reporting includes the following decision points or gateways, each of which requires associated reports.

Figure 5: Decision step gates

At the Data Gathering stage: After pre-screening has taken place, project ideas are subjected to a selection process designed to filter out ideas with little potential. The remaining project ideas are only then evaluated as to their costeffectiveness and classified as must-do or can-do projects. In the next step, high-potential ideas are developed into business cases and fleshed out. Ideas that seem unattractive at this point fail to pass the gateway and are rejected. The project ideas are presented in an overview showing how they fulfill the above criteria; this helps decide which ideas pass the gateway and which should be rejected.

At the Evaluation stage: Project dependencies must be evaluated to pinpoint dependencies within and between strategic buckets. (Defined top-down, strategic buckets represent areas of strategic focus and spending splits, and each project is assigned to just one bucket). This helps to pinpoint potential synergy. Any redundancies must then be eliminated by reconfiguring projects and by creating programs of projects. For this purpose, dependencies must be evaluated and presented in visual form to assist with decision-making.

Company-internal billing is based on rates set by the organisational units involved. Due to differing cost structures and fluctuating demand, internal billing rates must be reviewed regularly. Once capital constraints have been determined, supply and demand for specific resources must also be determined. Internal billing rates between organisational units can be recalculated on the basis of actual resource costs. This requires information on resource supply and demand as well as the underlying costs of the resources.

Prioritisation: Projects should be assigned priorities based on their perceived value, and a project ranking system must be developed. Project value can be either quantitative such as net present value, expected commercial value, return on investment, etc or qualitative such as strategic contribution, operational urgency, strategic alignment, risk, etc. Project value information is presented in the form of a score table or graphical chart, enabling decision-makers to evaluate the project portfolio using a wide variety of criteria. This leads to a more balanced assessment.

At the Approval stage: Following prioritization, the project portfolio is finalized. Based on the comparison and evaluation of quantitative and qualitative criteria relating to strategic importance, value and risk, a concrete scenario is selected for implementation. Decisions must be made as to which projects to execute, continue or cancel. To this end, alternative scenarios are compared using the above criteria. A change list must also be drafted, stating which projects are to be started, continued, postponed, brought forward, or abandoned.

Once a portfolio has been selected for implementation, the allocation of resources must be determined. The selected scenario dictates how resources need to be allocated to organisational units, and determines whether and what additional capacity (in-house and external) is required. An evaluation of how the selected portfolio affects resource availability and allocation is provided as decision-support.

The project portfolio selected also drives the allocation of capital. The scenario selected determines the investment required and the capital allocated to each organisational unit in the form of funding for in-house effort, outsourced effort, and investment. In addition, the budgets of the strategic buckets are reviewed and adjusted, providing baseline information for subsequent investment control/monitoring. An analysis of capital distribution is used as decision-support for approving the allocation of funds.

At the Control stage: Analysis of deviations is performed regularly while the projects in the portfolio are underway. Deviations are identified by comparing target and actual values; this method also provides information on their scale and severity. The project portfolio may require adjustment as a result. Decisionmaking on corrective action is facilitated by reports showing qualitative and quantitative parameters for the entire portfolio, and highlighting the impact of serious deviations from plans or targets.

Portfolio Management and IT Applications

Step 4 ‘WHAT IF’ analysis and project adoption: Once the organisation has its prioritised list of projects, it then needs to determine where the cutoff is based on the business plan and the planned level of investment of the resources available. This subset of the high priority projects then needs to be further analyzed and checked. The first step is to check that the prioritized list reflects the planned breakdown of projects based on the strategic allocation of the business plan. The Figure 6 shows the portfolio adopter designed to let executives or project managers conduct ‘what if’ scenario modeling and analysis.

1.5 RISK MANAGEMENT With the Information Technology, although management needs to be aware of all potential risks, operational risk is the primary risk associated with it. Operational risk (also referred to as transaction risk) is the risk of loss resulting from inadequate or failed processes, people, or systems. The root cause can be either internal or external events. Operational risk is present across all business lines. Operational risk may arise from fraud or error. Management’s inability to maintain a competitive position, to manage information, or to deliver products and services can also create and compound operational risk. Weak operational risk management can result in substantial losses from a number of IT threats including business disruptions or improper business practices. All organisations should properly identify, measure, monitor, and control operational risk. Management should distinguish the operational risk component from other risks to enable a stronger focus on operational risk mitigation. The board should ensure that a program exists to manage and monitor this risk. The program should address the institution’s tolerance for risk, the effectiveness of internal controls, management’s accountability in regards to risk mitigation, and the processes needed to manage IT effectively. Operational risk includes not only back office operations and transaction processing, but also areas such as customer service, systems development and support, internal controls and processes, and capacity planning. Operational risk from IT also affects credit, compliance, strategic, reputation, and market risks. Management should be aware of the implications of operational risk including:

•

Liquidity, interest, and price risks: Credit and market risks can materialize from external changes in markets, industries, or specific customers. Internal controls that rely heavily on the availability and performance of technology create additional operational risk exposure. For example, a failure to properly implement changes to underwriting, account management, or collection systems can lead to significant losses, and higher loan servicing and collection costs

•

Reputation risk: Reputation risk stems from errors, delays, or omissions in information technology that become public knowledge or directly affect business partners, customers and consumers resulting in a loss of confidential information and potential customer withdrawal of funds. Two activities that can lead to reputation risk are the unauthorised disclosure of confidential customer information and the hacking/modifying of an institution’s website

•

Strategic risk: Strategic risk can stem from inaccurate information or analysis that causes management to make poor strategic decisions. For example, IT management could decide to save money by delaying an infrastructure upgrade to increase network bandwidth, which could result in a business line losing market share due to an inability to compete.

•

Compliance (legal) risk: Compliance risk results from the institution’s inability to meet the regulatory and legal requirements associated with its IT products and services. Legal risk may lead to civil or criminal liability if, for example, an institution discloses confidential information or provides inaccurate or untimely consumer compliance disclosures.

IT management should have a corporate-wide view of technology. It should maintain an active role in corporate strategic planning to align technology with established business goals and strategies. It also should ensure effective technology controls exist throughout the organisation either through direct oversight or by holding business

lines accountable for IT-related controls. From a control standpoint, management should assess risks and determine how to control and mitigate the risks. Management should continually compare its risk exposure to the value of its business activities to determine acceptable risk levels.

Portfolio Management and IT Applications

IT Risk Management Process IT controls result from an effective risk assessment process. Therefore, the ability to mitigate IT risks is dependent upon risk assessments. Senior management should identify, measure, control, and monitor technology to avoid risks that threaten the safety and soundness of an institution. The institution should 1) 2) 3) 4)

plan for use of technology, assess the risk associated with technology, decide how to implement the technology, and establish a process to measure and monitor risk that is taken on. All organisations should have: • An effective planning process that aligns IT and business objectives; • An ongoing risk assessment process that evaluates the environment and potential changes; • Technology implementation procedures that include appropriate controls, and • Measurement and monitoring efforts that effectively identify ways to manage risk exposure.

This process will typically require a higher level of formality in more complex institutions with major technology-related initiatives. The risk identification and management process for technology-related risks is not complete without consideration of the overall IT environment in which the technology resides. Management may need to consider risks associated with IT environments from two different perspectives: •

If the IT function is decentralized, and business units manage the risk, then management should coordinate risk management efforts through common organisation-wide expectations.

•

If the IT department is a centralised function that supports business lines across shared infrastructure, management should centralize their IT risk management efforts.

Planning IT Operations and Investment Planning involves preparing for future activities by defining goals and the strategies used to achieve them. Information technology is an integral part of large number of companies like financial institution operations. Therefore, such companies like, financial institutions should integrate IT resources and investments into the overall business planning process. Major investments in IT resources have long-term implications on both the delivery and performance of the institution’s products and services. Plans may vary significantly depending on the size and structure of the organisation. Every organisation should strive to achieve a planning process that constantly adjusts for new risks or opportunities and maximizes the value of IT to the organisation. Management should always document plans; however a written plan does not guarantee an effective planning process. Management should measure specific plans by whether they meet the organisation’s business needs. For all plans, the examiner should evaluate the process as well as the written product. A sound plan requires the board of directors, senior management, and user involvement in the planning process.

Information Systems

The board of directors should review and approve the plan. Senior management participates in formulating and implementing the plan. The individual departments and functional areas identify specific business needs and, ultimately, implement the plans.

Risk Identification and Assessment Operational IT planning should identify and assess risk exposure to ensure policies, procedures, and controls to remain effective. Information security risk assessments are essential. The assessments should identify the location of all confidential customers and corporate information, any foreseeable internal and external threats to the information, the likelihood of the threats, and the sufficiency of policies and procedures to mitigate the threats. Management needs to consider the results of these assessments when overseeing IT operations. The risk assessments should cover all IT risk management functions including security, outsourcing, and business continuity. Senior management should ensure ITrelated risk identification and assessment efforts at the enterprise-wide level are coordinated and consistent throughout the organisation. A strong, high-level, risk assessment process provides the foundation for more detailed assessments within the functional risk management areas. An effective IT risk assessment process will improve policy and internal controls decisions across the organisation. Senior management can use risk assessment data to make informed risk management decisions based on a full understanding of the operational risks. Small institutions with less complex systems may have a more simplified risk assessment process. Regardless of the complexity, the process should be formal and should adapt to changes in the IT environment. Examiners should measure the effectiveness of the process by evaluating management’s understanding and awareness of risk, the adequacy of formal risk assessments, and the effectiveness of the resulting policies and internal controls.

Ongoing Data Collection Understanding the institution’s environment is the first step in any risk assessment process. Senior management should incorporate information on IT issues such as resource limitations, threats, priorities, and key controls from several sources. In developing a formal risk assessment, management should collect and compile information regarding the organisation’s information technology environment from several locations including:

•

IT systems inventories are critical to understanding and monitoring the tactical operations of the institution’s information technology as well as to identifying the access and storage points for confidential customer and corporate information.

•

IT strategic plans provide insight into the organisation’s planning process. Review and analysis of the strategic plans as part of the risk assessment process may spotlight developing risk exposures or other deficiencies that limit the institution’s ability to implement strategic priorities.

•

Business recovery and continuity plans prioritise the availability of various business lines to the institution and often encompass restoration and provision of control, customer service, and support. The plans can offer insight into the organisation’s critical operating systems and the control environment.

•

Due diligence and monitoring of service providers can present valuable information on the servicer control environment. The information is necessary for a complete risk assessment of institution’s information technology environment.

•

Call center issue tracking reports can often indicate potential performance or control issues if the problem reports are aggregated and analysed for repetitive or common issues.

•

Department self-assessments on IT-related controls can provide early identification of policy noncompliance or weaknesses in controls.

•

IT audit findings provide insight into the veracity and responsiveness of the institution’s staff and management, commitment to policy compliance and internal controls.

Portfolio Management and IT Applications

Risk Analysis Management should use the data collected on IT assets and risks to analyze the potential impact of the risks on the institution. The analysis should identify various events or threats that could negatively affect the institution strategically or operationally. Management should evaluate the likelihood of various events and rank the possible impact. Some examples of events that could affect the institution include the following: •

Security breaches: Security breaches that can affect the institution include external and internal security breaches, programming fraud, computer viruses, or denial of service attacks

•

System failures: Common causes of system failures include network failure, interdependency risk, interface failure, hardware failure, software failure, or internal telecommunication failure

•

External events: Institutions are also exposed to external threats including weather-related events, earthquakes, terrorism, cyber attacks, cut utility lines or wide spread power outages that bring about system or facility failures.

•

Technology investment mistakes: Mistakes in technology investment including strategic platform or supplier risk, inappropriate definition of business requirements, incompatibility with existing systems, or obsolescence of software may constrain profitability or growth.

•

Systems development and implementation problems: Common system development and implementation problems include inadequate project management, cost/time overruns, programming errors (internal/external), failure to integrate and/or migrate successfully from existing systems, or failure of system to meet business requirements.

•

Capacity shortages: Shortages in capacity result from lack of adequate capacity planning, including the lack of accurate forecasts of growth.

Once the institution has identified the universe of risks, management should estimate the probability of occurrence as well as the financial, reputation, or other impact to the organisation. Organisational impacts are highly variable and not always easy to quantify, but include such considerations as lost revenue, flawed business decisions, data recovery and reconstruction expense, costs of litigation and potential judgments, loss of market share, and increases to premiums or denials of insurance coverage. Typically, risk analysis ranks the results based on the relationship between cost and probability.

Prioritisation Once management understands the institution's technology environment and analyzes the risk, it should rank the risks and prioritize its response. The probability of

Information Systems

occurrence and the magnitude of impact provide the foundation for reducing risk exposures or establishing mitigating controls for safe, sound, and efficient IT operations appropriate to the complexity of the organisation. The overall risk assessment results should be a major factor in decision making in most IT management responsibility areas including: • • • • • • • • •

Technology budgeting, investment, and deployment decisions Contingency planning Policies and procedures Internal controls Staffing and expertise Insurance IT performance benchmarks Service levels for internal and outsourced IT services and Policy enforcement and compliance

Monitoring Management and the board should monitor risk mitigation activities to ensure if identified objectives are complete or are in process. Monitoring should be ongoing, and departments should provide progress reports to management on a periodic basis. Ongoing monitoring further ensures that the risk assessment process is continuous instead of a one-time or annual event. Key elements of an effective monitoring program include: • • •

Mitigation or corrective action plans; Clear assignment of responsibilities and accountability, and Management report.

IT Controls Implementation These guidelines are applicable to both in-house and external provider situations.

Policies, Standards, and Procedures Management should adopt and enforce appropriate policies and procedures to manage technology risk. The effectiveness of these policies and procedures depends largely on whether they are used by internal staff and vendors. Testing compliance with these policies and procedures often helps to identify and correct problems before they become serious. Clearly written and frequently communicated policies can establish clear assignments of duties, help employees to coordinate and perform their tasks effectively and consistently, and aid in the training of new employees. Senior management should that ensure policies, procedures, and systems are current and well documented

Internal Controls The institution should adopt adequate controls based on the degree of exposure and the potential risk of loss arising from the use of technology. Controls should include clear and measurable performance goals, the allocation of specific responsibilities for key project implementation, and independent mechanisms that will both measure risks and minimize excessive risk-taking. Management should re-evaluate these controls periodically. Management practices associated with general controls include:

• • • •

Reporting effectiveness to the Board of Directors; Periodic review and updating of policies, standards, and practices; Regular review of internal and third party audit results; Review of service level agreements, and

•

Review of control metrics including issues and corrective action plans.

Adequate internal controls should be structured to assure senior management that: • • • • • • • •

Portfolio Management and IT Applications

Personnel create, transmit, and store records and transactions in a safe and sound manner; Adequate segregation of duties exists; MIS data are reliable and the reporting cycle is adequate; Necessary Quality Checks have been implemented; Operating procedures are efficient and effective; Procedures are in effect to assure continuity of business; The institution identifies and monitors high-risk conditions, functions, and activities, and There is proper adherence to management standards and policies, applicable laws and regulations, regulatory statements of policy, and other guidelines.

Independent audits can verify that these controls exist and are functioning effectively.

Personnel All organisations should mitigate the risks posed by IT staff by performing appropriate background checks and screening of new employees. In addition to staff, the controls in this section are relevant for vendor personnel, consultants, and temporary staff that support the IT function. Typically, the minimum verification considerations include: • • •

Character references; Background checks including confirmations of prior experience, academic credentials, professional qualifications, or criminal records, and Confirmation of identity from government issued identification.

Insurance In establishing an insurance program, management should recognise its exposure to loss, the extent to which insurance is available to cover potential losses, and the cost of such insurance. Insurance programs should be commensurate with the complexity and risk of each institution. Management should weigh these factors to determine how much risk the organisation will assume directly. In assessing the extent of that risk, institutions should analyse the effect of an uninsured loss on themselves and any affiliates or parent companies. Management should also review a company’s financial condition and/or credit rating reviews when deciding on an insurance company. Once management has acquired appropriate insurance coverage, it should establish procedures to review and ensure its adequacy. These procedures should include, at a minimum, an annual program review by the board of directors

1.6 DISASTER MANAGEMENT A disaster is defined as a sudden misfortune that is ruinous to an undertaking. This means that there is little time to react at the time of the misfortune. Preparations are required to have been made in advance. The focus should, therefore, be on disaster planning. The first step in disaster planning is to assess risk. A computer or network disaster typically involves loss of or damage to data, the inability of programs to function, or the loss of data communication. Risk assessment answers the question, what is the probability a particular disaster to occur and how serious will be the effect likely to be if it does occur. Among the disasters that should be assessed are natural disasters such as floods, fires, and earthquakes and manmade disasters such as air conditioning failures, viruses, hacking, and vandalism. The line between the two is not clear-cut

Information Systems

because a flood can be the result of vandalism to a water pipe and a fire can be deliberately set as an act of vandalism. A risk assessment matrix should be created, one which puts the probability on one axis and the effect on the other, with the risk factor fixed by the combination of the two factors: Effect may be classified as Major, Moderate, and Minor. Probability of Risk may be classified as High 5 4 3 Moderate 4 3 2 and Low 3 2 1 on a 5 point scale. A risk factor of 5 requires much more attention and warrants a much greater outlay of resources than a risk factor of 1. The risk factor will vary by area of the country, nature of the community, and type of organisation. In much of California, earthquakes would be rated a risk factor of 5; along the flood plains of the Mississippi River flooding would be a risk factor of 5. Viruses, while probable, usually have only a minor effect, therefore, they would have a risk factor of 3. Hacking, this rates highly probably for Fortune 500 companies; rates low for smaller organisations, but may rate a risk factor of 3 because its effect may be major. In many areas floods are likely to be the result of a broken pipe and have a low risk factor of 1 or 2 because their effect tends to be localized and, therefore, minor or moderate. The second step in disaster planning is risk reduction. This is achieved by lowering the risk factor by reducing the probability, reducing the effect, or both. For example, while no disaster plan can reduce the probability of an earthquake, housing the organisation in California that is quake-resistant should reduce the effect of one. Placing a computer room where there are no overhead pipes reduces the probability of flooding; rack-mounting the computer hardware so that it is several inches above the floor reduces the effect. Installing anti-virus software reduces the probability of a disaster; regularly backing up all data reduces the effect. The third step in disaster planning is to earmark resources. Disaster planning need resources (takes time and expertise), but it is within the means of most organisations. A small task force of staff members, given time to read the literature and contact other organisations that have done disaster planning, can develop a disaster plan in weeks or months. What is difficult for many organisations is finding separate funds to carry out the plan. Retrofitting an old building to withstand earthquakes can cost hundreds-ofthousands or millions of dollars; mirroring a database of a large organisation can cost huge amount of money. Each risk factor must, therefore, have a price tag associated with it. An organisation has to decide whether the risk reduction is worth the price and, if so, seek the funds to pursue the risk reduction. It may not be realistic to lower the highest risk factors first because the funds may not be available. It may be necessary to focus on lowering risk factors for which the resources are available. Heat/smoke and water detectors are within the means of most organisations and should not be skipped over just because the risk factor is not a 4 or 5. The fourth step in disaster planning is to identify Common Disaster Plan Elements. Every disaster plan should set forth both preventive measures and remedies in at least the following areas:

Servers

Every organisation with one or more servers should have a server room that is secured with a combination lock such as a Simplex and a reinforced door with a deadbolt at least 1.5 inches long. If the room is not windowless, the windows should be barred. The room should have both fire/heat detection and water detection sensors which set

off a local alarm and send a signal to an off-premises monitoring facility. At a minimum, it should have fire extinguishers suitable for electrical fires. An organisation that has hundreds-of-thousands of dollars in equipment in its server room should consider a built-in fire suppression system.

Portfolio Management and IT Applications

Excess heat is, by far, the most commonly reported cause of server downtime and damage. An office should, therefore, augment its building air conditioning with a room-size air conditioner that kicks-in only when its thermostat shows that the temperature in the room has risen above a office specified level, typically 68 degrees. An additional safeguard is available, a thermostat inside any cabinet which has a cooling fan. When a fan fails and the temperature rises, an alarm should be triggered. Water damage is the second-ranking cause of server downtime and damage, although the damage is rarely greater than moderate. There should be no water pipes in the ceiling above the room, or in the walls that enclose it. The server(s) and associated peripheral equipment should be rack-mounted so that up to six inches of standing water will not affect the equipment. Power irregularities are the third-ranking cause of server downtime and damage. An UPS (uninterruptible power supply) should be used to protect all servers against surges, spikes, brownouts, and blackouts. The UPS should have a rating which is it least twice the total KVA requirements of the devices it protects. KVA (Kilo Volt Amperes) is a rating that is calculated by multiplying the number of volts by the number of amperes and dividing by 1,000. While a office may not want to operate its servers on battery back-up for an extended period, the UPS should provide power long enough for an orderly shutdown of all servers. The database server should be protected by its own firewall, preferably a proxy-server between it and the Web server on which the patron access catalog is mounted. A proxy server shields the database server from direct access by initiating a separate inquiry, rather than passing the external inquiry through to the database server. The firewall can be on the same hardware platform as the database server. The Web server can support not only the patron access catalog, but also other files and a gateway to electronic resources outside the organisation. It should include remote patron authentication software so that access to other than records the organisation wishes to make available to everyone is limited to those who are authorized users. Each server should be configured with a logging tape drive--typically a 4mm or 8mm streaming tape drive-- so that all information written to disk is also written to tape. Each evening the logging tape should be removed and stored away from the server room and a new tape mounted for database back-up. Overnight, the content of the disk drives should be written to tape. The next morning, the back-up tape should be removed and stored away from the server room and a new tape mounted for logging that day's transactions. It will then be possible to restore all files using the most recent back and logging tapes. Magnetic media can become unstable with repeated use, therefore, seven logging tapes--one for each day of the week--should be used. Seven back-up tapes should also be used. All of the tapes should be replaced at least every year. An organisation may choose to do a back-up only once a week. If so, all of the logging tapes for the week should be saved so that they and the previous week's back-up tape can be used to restore the files. The logging tapes and the previous week's back-up tape should be stored away from the server room. In a large facility than may be at the opposite end of the building, but for smaller facilities it should be off-site. At least once per week, a current back-up tape should be sent to an off-site storage facility to protect against the loss of the on-site back-up tape. Organisations that can afford RAID (Reduced Array of Inexpensive Disks) should configure their servers with them. RAID technology mirrors everything written to one

Information Systems

disk on another disk. If a disk fails, the mirroring disk provides access to the information without resorting to the rebuilding of files from the combination of backup and logging tapes.

Network An organisation can do a great deal to secure a LAN (local area network), but only a limited amount to secure a WAN (wide area network). The former usually is limited to a single building or part of a building; the latter usually ties two or more LANs together using a telco or other common carrier's circuits. The telco or common carrier has the responsibility for its portion of the WAN. Wan should be protected there appropriate firewalls. The preferred LAN topology is a hybrid star, one that has several central star network points linked in a star. In other words, several desktop clients are connected to a hub, and several hubs are connected to yet another hub. The cabling from the desktop clients to the hubs can be relatively inexpensive Category 5 UTP (unshielded twisted pair); the wiring among hubs should be STP (shielded twisted pair) or fiber optic to dramatically improve performance and security. Network hardware should be secured in locked data communications closets or cabinets. All data jacks should be capable of being de-activated when no office equipment is connected to them. The practice of distributing a large number of data jacks around a building for use by patrons with laptops should be avoided unless these jacks are on a separate LAN segment that can be isolated from the database server of the automated office system. Patrons need access only to the patron access catalog, and possibly to other servers: Web, Internet, CD-ROM, image, etc. If a wireless LAN is implemented, it should access only a segment of the officeâ&#x20AC;&#x2122;s LAN, one that can be isolated from the database server of the automated office system. The most vulnerable part of a office's network is the connection to the Internet, both access from the Internet to its servers and from its servers and clients to the Internet. Fortunately, it is cost effective to protect a office's database server with its own firewall so that there is protection against in-office users, as well as external users. More vulnerable are the other servers and the clients or desktop workstations. Most offices seek to protect them only from users outside the office. This can be done by installing a network firewall. The firewall can be configured not only to restrict access to specific categories of users or specific types of queries, but can also be configured to facilitate access to office-selected resources.

Clients PCs and Macs are the most vulnerable technology in offices because they can be compromised by staff and patrons who behave unwisely by downloading attachments or bringing in software and data disks from outside the office. Viruses are the greatest threat. An Anti-virus software is absolutely essential. Products from companies such as McAfee and Norton detect computer virus signatures and alert the user to them before they enter the client; however, antivirus products are of little value if they are not regularly updated. Literally hundreds of new viruses are unleashed every week, therefore, anti-virus software should be updated at least weekly by downloading the latest version.

Almost all viruses travel via e-mail attachments or diskettes. Staff should, therefore, be instructed not to open an attachment if the source of the e-mail is not known or the attachment is not expected. They should be particularly suspicious of attachments with strange-sounding titles. When in doubt, the sender should be asked by return e-mail to describe the contents of the attachment. Staff should be instructed not to bring

software from home for loading on office machines, nor to carry diskettes back and forth between home and work machines.

Portfolio Management and IT Applications

The fifth step in disaster planning is to establish Recovery Procedures. It is important to state in the disaster plan not only what recovery procedures are to be followed if a disaster occurs, but also who has what responsibility. Who calls whom and what information should they be prepared to give? Who performs the needed diagnostics? Who restores the files? What are the instructions for packing and shipping the corrupted files? Communication is of great importance during a disaster. It should not be assumed that regular telephone service will be available. Key personnel should have cell phones for use when regular telephone service fails or is overloaded. The cell phone in the server room should be stored in a wall-hung watertight cabinet on the wall adjacent to the entrance door. The instructions for dealing with a computer/network disaster should be stored in the same cabinet. All important telephone numbers should be stored in each cell phone. If a disaster affects more than the office, the cellular service may be swamped with calls. It is, therefore, a good idea to instruct the operator in the server room to use the redial and speaker features of the regular telephone while seeking to get through on the cell phone. A designated operator for each hour the office is open is a good practice. This may be a member of the circulation desk's support staff ,the staff which usually is in the office all of the hours the office is open. The designated person would perform the end-ofday swap of the logging and back-up tapes as part of his/her routine duties. Otherwise, s/he would leave her/his regular duties only when there was a problem. The designated operator on duty at the time of a disaster should have instructions to call the support desks for the servers that have been affected. The numbers should be encoded in both the server room's telephone and the cell phone that has been provided as a back-up. Each designated operator should participate in an occasional disaster drill that simulates an actual disaster that affects one or more servers. Designated manager to support the designated operator who may encounter a situation that overwhelms him/he should also be considered. There should always be a designated manager in the office or available by telephone 24 hours per day, seven days per week. While there may rarely be a need to decide about evacuation of the office or another major action, the capacity to do so must be in place. An external resource is the vendor of an automated office system is an important resource in diagnosing problems that result from a disaster. When drawing the contract, make it clear that the vendor shall be liable not only for the performance of the central site and its client software, but it shall undertake remote diagnostics through the network to the desktop. In other words, it shall pinpoint a problem regardless of where it is. If coverage has not been purchased for 24 hours a day and seven days a week, there should be provision for emergency support at agreed upon hourly rates outside the normal coverage hours. If the database server for the automated office system is affected by a disaster, the vendor's trouble desk should be called so that remote diagnostics can be performed and guidance can be obtained. If the vendor of the automated office system is not responsible for the management of hardware maintenance, hardware problems should be referred to the manufacturer's support desk. Sources of support for all other servers should be identified and their telephone numbers must be encoded in the server room's telephone and in the cell phone that have been provided for back- up.

Information Systems

Most offices do not have the luxury of a network specialist. A office should, therefore, rely on the networking staff of a parent organisation or consider contracting with a network support service for remote diagnostics and recovery assistance. While these firms are found in most major cities, a regional or national firm with experience in automated office systems should be considered. One or more data recovery firms should be identified. These firms recover data from hard drives, diskettes, or any other storage medium that has been damaged by flood, fire, physical impact, or a virus. A large national firm usually is able to accommodate a rush order better than a smaller local one. Insurance coverage for disaster is part of the insurance plan by larger organisations. The office should carry insurance that includes coverage for its servers, network, and clients. In order to make claims, it is essential to have an absolutely current inventory of all hardware and software, including purchase data and price. A copy of this information should be stored at a remote site. In case of damage that is visible, photographs should be taken promptly after the disaster to substantiate an insurance claim.

1.7 PORTFOLIO MANAGEMENT ISSUES AND CHALLENGES In implementation of a portfolio management application, there are many successes associated with it, there are many lessons learned also. Issues and challenges which need to be understood are: 1)

Portfolio Management system acceptance

Since true success of portfolio management system lies in active involvement of all concerned, it is important that the systemâ&#x20AC;&#x2122;s benefit are recognized and appreciated by them. The application champion (business side and application administrator) for this purpose may find themselves constantly â&#x20AC;&#x2DC;selling the benefitâ&#x20AC;&#x2122; of the tool. They may need to become evangelist for portfolio management and have the stick-to-it-ness to weather the storm. Resistance may be strong and critics will most likely outnumber advocates. They will need to continually prove the value of the application and its data. This is not easy, it is not pretty, and it will become frustrating. This may also require doing some behind the scenes magic to prove that the application has value. There will also be a significant training and learning curve. Even if the organisation is mature in its artifacts, processes, methodology, and terminology, there will be a new means of recording and reporting it. 2)

Real Time Readiness

In the past, a project manager had control over when information about the project was shared and available for all members of the project team and for executives. The project manager could masks blemishes and possible lapses by controlling when information was shared. For example, if the project manager led a project status call every other Thursday, they could possibly wait until Wednesday night to update their issues report. If an issue was due a week before, the report might not get updated until before the review. Now with a portfolio management system, the day the issue becomes past due it can be flagged in reports. The PM might now have to do daily management of the issues. 36

Conformity to override Flexibility

One of the benefits of a portfolio management system is the ability to track information consistently across projects. Latest maturity models call for consistency across the organisation. A portfolio manager enforces conformity and an individual PM will loose some of the flexibility they have in tracking and reporting project status. For example using issues again, a PM might want to have a way to indicate an issue is resolved prior to being closed. This way they could have a report that shows issues ‘resolved’ and ready to go off the list. Another project manager may be more of the mindset that it goes straight to closed. People can refer to a closed issues report to see what’s been closed in the past week. While we can not say which method is better, a portfolio management issues workflow will force the process. If a program manager wants to have consistency in reporting of all projects across the portfolio, an individual will need to sacrifice some of their individual style to conform to the portfolio work flow. 4)

Portfolio Management and IT Applications

System to be for the Users

As you take project management from desktop applications and non-integrated artifacts, you have risen to the level of application management. With application management, comes the entire cycle of enhancement requests, workflow requests, and even field names. A PM might not get the feature he/she wants – or may have to compromise. 5)

Requirement of an Application Administrator

First thing to do when implementing a portfolio management system is to appoint an application administrator and an application change control process. We need to budget a person’s time into the care and feeding of this application. There is no rule of thumb regarding how many Full Time Equivalents (FTE’s) are required for application administration, but it will have a direct relationship to the organisational maturity, the business process maturity, and the breadth of the audience. In one of the organisation where PM was implemented, workgroups was brought onto the Portfolio Management Application involved new people, new business model, Beta applications, and new customers. This group ended up with an application administration team that looked at the business request and two trained administrators that did the physical administration (defining views, reports, filters, adding users, creating work flows etc.) There were also two team members who looked at templates and business needs and helped set priorities with the application administrators. Application administration is a different responsibility than a system administrator or a data base administration. An application administrator needs a strong skill set balanced between knowledge of project management principles and methodologies, knowledge of the business, and technical knowledge of data bases, SQL, report writing, and trouble shooting. A system administrator focuses on making sure the operating system and the hardware work, the application administrator makes sure the application meets the business need. The organisation may head for failure if it is thought that a system administrator can provide the business needs fulfilled by an application administrator. Finally, there will be changes and churn on the application. It is going to need someone to manage those, train the users on changes, and prioritise the work. We can imagine many organisations under estimate the care and feeding needed to keep an application viable. 6)

Making it business management application requires sincere efforts by all

Everybody has the best of intentions, but taking care of the low level minutiae that makes up a portfolio management system is cumbersome, time consuming, and some people may see it of little value. A basic premise of a portfolio application is that executive levels of information can flash from multiple projects at one time. However, to get that executive level, the lowest of details must be there and many project managers will not put it in, unless they are hounded to put it in, or they are ‘punished’ if they don’t. Excellence is a mindset and the middle manager must

Information Systems

maintain vigilance to insure compliance. There’s an entirely integrated thread with this thought and that involves cross-organisational compliance so the portfolio management tool transcends a project management application and becomes a business management application. The impact, both cultural and technical, aspects of this concept are way to deep to cover in this thinking 7)

Reports grow exponentially if not reasoned out

Input is one aspect of an application, output is another and there is an exponential demand for output. The main outcome of a well organised report is that there is always tendency to request for a new report or the same report with a ‘slight modification’. We feel there is a way to stop this. The requests will continue to flow in and unless and until you reason out the and bring out new report only when there is genuine need for the same. However, it is difficult task to make people agree. 8)

People will Blame the System for their Own Lapses

It is a rule of human nature. People will blame the system to hide their own insecurities and lack of knowledge. No matter what system is created, it will have its own set of idiosyncrasies and there will be some things the application will require that make no sense at all, but the application requires it. Be thick skinned and prepared for people to blame the system for their problems. 9)

Mental block

No matter how much you train, hand hold, and evangelize, some people just won’t get the idea of project rolling up to program, rolling up to portfolio. You may encounter resistance as to why do I need to do it this way? Portfolio management is a completely different perspective and does require a certain amount of abstract visualizing (is there any other type?) – some people who are Great silo-based project managers, will just not get the inter-dependencies of projects within a portfolio management system. While work with these people, one be careful and understanding, the odds are that they want to do well, and they have a wealth of knowledge and experience, but they have a mental block. 10)

Customisation efforts increase with time

Every salesman who pushes a portfolio management system touts its flexibility and the capability to customize the system to meet your business need. Most give you the capability to add custom fields and create your own reports, but as stated earlier the demand for various outputs never ceases. In the infancy of the system you will be able to quickly add a custom field to meet a need, but after months of customization here and there, the ripple effect can be enormous.

1.8 TOOLS AND TECHNIQUES The portfolio management tool market is growing: There are large numbers of vendors who are offering Portfolio Management Tools. Each vendor talks about the salient features of his tools and offers a variant method for the Portfolio. However, each vendor is offering automation of Portfolio process to some degree. Coordinating information across this portfolio management domain itself dictates a number of key product features that one should look for when considering a tool to assist with automating the portfolio management process. Three key requirements include: •

Common repository. A single data repository that each group will access for reporting will be a requirement for an organisation moving to full IT portfolio management. Multiple groups, each using separate tools and repositories, will quickly lead to inaccuracy and conflicts as data becomes out of sync.

•

Direct data collection and interchange. Data should enter the portfolio management tools directly and without manual input. Requiring project managers to enter information for each project will also quickly lead to data corruption or omissions. Resource utilisation and project information should be gathered directly from project management systems and spending data fed into the system directly from financial management tools.

•

Configurable data views and portals: Each user of the tool will have different requirements. When considering a portfolio tool, make sure that the interface is configurable for each user constituency, centralising common tasks and reports, and allowing for the addition of reports and functions as the portfolio management process grows, matures, and expands.

1.9 EMERGING TECHNOLOGIES

Portfolio Management and IT Applications

In the Emerging Technologies three key technology themes (as per Gartner) are expected to be having significant growth and need to be watched: (a) Technologies that will enable the development of Collaboration, (b) Next Generation Architecture, and, (c) Real World Web. a) Collaboration A number of key collaboration technologies designed to improve productivity and ultimately transform business practices are: •

Podcasting: Podcasting offers a way to ‘subscribe’ to radio programmes and have them delivered to your PC. It is predicted that podcasting subscriptions will grow increasingly important as the market for content continues to fragment, which will lead to a massive shift in radio, and ultimately TV content delivery. Podcasting is an extremely efficient method for delivering audio and spoken-word content to niche audiences and as such could become an important corporate communications tool.

•

Peer to Peer (P2P) voice over IP (VoIP): Vendor-proprietary P2P VoIP applications are under development although security concerns still need to be addressed. Services like Skype currently enjoy significant consumer adoption and are beginning to make inroads into the business landscape. It is predicted that the technology will be important for collaborative and multimedia applications as well as low-cost communications.

•

Desktop Search: Also known as personal knowledge search, this is an individual productivity application, residing on the desktop and using local processing power to provide search-and-retrieve functionality for the desktop resident’s local e-mail, data store and documents. Google, Microsoft and Yahoo are competing for customer attention, adding to the hype but customers not exhibiting much interest in buying solutions. However desktop search will become a standard feature in Microsoft Longhorn, currently planned for 2006 and should reduce content recreation, increase content reuse whilst raising productivity.

•

Really Simple Syndication (RSS): RSS is a simple data format that enables web sites to inform subscribers of new content and distribute content more efficiently by bypassing the browser via RSS reader software. RSS is widely used for syndicating weblog content but its corporate use is only starting to be tapped for activities such as corporate messaging. Its simplicity makes it easy to implement and add to established software systems. It is predicted that RSS will be most useful for content that is ‘nice to know’ rather than ‘need to know’.

•

Corporate Blogging: This involves the use of online personal journals by corporate employees, either individually or in a group, to further company goals. It reached the peak of hype in 2004 although mainstream firms have not yet got involved. Its impact will be on projecting corporate marketing messages primarily and secondarily in competitive intelligence, customer support and recruiting.

•

Wikis: A simple, text-based collaborative system for managing hyperlinked collections of web pages; it usually enables users to change pages or comments created by other users. Wikis are becoming available from commercial vendors, in addition to many open-sourced products, but not yet from established enterprise vendors. However, they are widely used as

Information Systems

collaborative, distributed authoring systems for online communities, especially those using open-source projects. It is predicted that Wikis will impact ad hoc collaboration, group authoring, content management, web site management, innovation, project execution and research and development. b) Next Generation Architecture Next generation architecture will constitute the third big era in the IT industry’s history (the first having been the hardware era and second belonging to software). These emerging technologies will form key pillars of the new architecture: •

Service Oriented Architecture (SOA): SOA uses interactive business components designed to be meaningful, usable and useful across application or enterprise boundaries. Despite the current disillusionment with SOA, it is expected support for SOA to grow and for it to mature as a technology within ten years although many changes in user and vendor organisations and technologies are required before SOA reaches its full potential. However, in the longer term, it is believed that SOA has the potential to be transformational to a business.

•

Web Services-Enabled Business Models: These productivity-boosting models represent a new approach to doing business among enterprises and consumers that would not have been possible without the benefits of webservices. However enterprises are still wrestling with what web services will do and it is expected that the potentially transformational impact of Web Services-Enabled Business Models will have to wait for more-mature standards and clearer examples.

•

Extensible Business Reporting Language (XBRL): This is an ExtensibleMarkup-Language-defined standard for analyzing, exchanging and reporting financial information. XBRL helps organisations meet multiple financial reporting needs through a single instance of financial data. It also improves the timeliness and accuracy of financial and regulatory reporting, validation and distribution. XBRL enables integration, aggregation, validation and comparison of financial data. It also automates sourcing and the review of financial data for activities such as loan acceptances, investment portfolio management and risk reviews. Financial accounting software vendors are already incorporating XBRL while regulatory and transparency pressures increase the significance and likelihood of XBRL adoption. However, there have been setbacks in XBRL adoption in the past year; the most significant have been delays in the FDIC and FSA projects that will mandate XBRL reporting.

•

Business Process Platforms (BPP): BBP provide business process flexibility and adaptability. They use SOA design principles and are metadata and model driven. It is believed that Business Process Platforms will enable business process fusion and move innovation from business application vendors to BPP ecosystems. Ultimately they will replace customized business applications and custom development by extending core applications platforms with composite applications.

c) Real World Web It is believed that adding networking, sensing and processing to real-world objects and places is creating a ‘Real-World-Web’ of information that will enhance business and personal decision-making: 42

•

Location-aware applications: These are mobile enterprise applications that exploit the geographical position of a mobile worker or an asset, mainly

through satellite positioning technologies like Global Positioning System (GPS) or through location technologies in the cellular network and mobile devices. Real-world examples include fleet management applications with mapping navigation and routing functionalities, government inspections and integration with geographic information system applications. Mobile workers will use either a PDA or smart phone, connected via Bluetooth to an external GPS receiver, or stand-alone positioning wireless device. •

Radio Frequency Identification: Otherwise known as RFID, passive Radio Frequency Identification has been somewhat over hyped in recent years although vehicle-based systems are strong. It involves the tagging of very small chips to arbitrary types of objects. These chips transform the energy of radio signals into electricity then respond by sending back information that is stored on the chip. The most conducive environments for passive RFID are chaotic or unstructured business processes where RFID's ability to read without a direct line of sight gives it the edge over traditional bar-coding methods. These might include such diverse activities as manufacturing, healthcare, logistics, animal tracking and laundry automation.

•

Mesh Networks — Sensor: Mesh Networks are ad hoc networks formed by dynamic meshes of peer nodes, each of which includes simple networking, computing and sensing capabilities. Potential impact areas include low-cost industrial sensing and networking, low-cost zero management networking, resilient networking, military sensing, product tagging and building automation.

1.10 SUMMARY In this unit, we have discussed practically all aspects of the portfolio management. We have covered starting from what is portfolio management to its techniques, methods, tools, issues relating to it and its implementation procedure. This is one of the most acceptable procedure for evaluation of software projects these days. It is suggested that this study may be further supplemented by completing case studies on this topic. Another very important area covered in this unit is risk assessment and preparation for the disaster management as well as recovery from the disaster. With the growing dependence on information systems, preparedness for any eventuality is definitely a wise thing. It is a matter of concern that after the tragedy so many people and authorities talk about it but eventually keep on hanging on it till next tragedy happens. So let us look forward not to this mistake and prepare for it. Emerging technologies discussed in this unit are basically for motivating all students to cultivate the habit of looking around the Internet and other places to keep abreast to the trend.

2.0 INTRODUCTION There is a saying that specialist will be ‘one who knows everything about nothing’ or in a layman language we can say that ‘knowing more and more about less and less’. The development of IT has followed the same pattern, at first we had the study of ‘computers’ then further we studied of hardware and software. Software became further specialised into system software and application software. ERP is a living example of new-fangled application software. Achieving and maintaining competitive advantage is the underlying principle for every business around the world. Companies are struggling nowadays, conversely, with the integration of information from diverse contrasting IT systems and are spending approximately 40% of their IT budgets on maintaining such legacy systems. To meet this challenge, companies are investing considerably in enterprise information system which in general known as Enterprise Resource Planning (ERP) applications. It had been sighted that ERP is a key enabler of business process transformation and IT automation. As a substance of fact, gaining strategic advantage is often cited by enterprises as a key reason for implementing ERP. Over recent years the attainment, accomplishment and exercise of Enterprise Resource Planning (ERP) Systems has turn out to be a standard facet of most of the corporate and institutions. At this juncture most of the literature on ERP implementation has focused on the early stages of the ERP lifecycle: adoption, resolution, acquisition and implementation. This unit tells the fairy-tale of ERP systems as a commercial software package that enables the integration of transactionoriented data and business processes all the way through an enterprise. ERP systems endow with cross-organization integration through embedded business processes and 46

are by and large composed of numerous modules including human resources, sales, production, purchase and finance. During the 1990s ERP systems were the de-facto standard for replacement of legacy systems in large companies (Parr and Shanks 2000). This unit will outline three (of the several) enterprise applications and business driver’s service providers can use to discriminate themselves. We will examine the concepts & purpose of effective enterprise resource planning (ERP), customer relationship management (CRM), and Supply chain management (SCM). We will also demarcate the major aspects of all, examine the drivers and impacts of each, and reflect on how each relates to the service providers’ product sets. If we go into the depth of enterprise resource planning system life cycle or rather ERP System Life cycle, the Figure 1 can furnish an elaborate view as the whole process consists of four steps which starts with Step-1 Assess: Provide information about cost, size of the package, when to buy, what to buy, what is right, what is wrong whether to go for inhouse ERP or invites ERP vendors. Step-2 Select: Once the assessment is done next task is to select the module which is an utmost essential, lets take an example of HLLA FMCG MNC, in India is a marketing oriented company, is in the process to implement the ERP module then it could be beneficial for the company to select the marketing modules. Step-3 Implement: Once the selection process is completed, the implementation starts. It is again a very careful and sensitive stage as implementation is not a one-day job and it takes years to go for final touch. In actuality implementation is a joint effort between internal & external team. At last Step-4 Support: the annual maintenance contact, in a layman term. It is significant as two different kinds of mindsets are going to inter-mingle, i.e., vendor side and the customers.

ERP systems can provide the foundation for a wide range of e-commerce–based processes, including web-based ordering and order tracing, inventory management, and built-to-order goods. This unit examines the pros and cons of ERP systems, explains how they work, and highlights their role. We begin by explaining the background of ERP systems and goes on to discuss specific systems, and their capabilities. The unit contains several detailed case studies and will be an invaluable guide to managers and consultants working with ERP systems. It will also be a useful reference for other students taking courses in information systems.

2.1 OBJECTIVES After reading this unit, you should be able to:

• • •

describe the ERPs evolution and stages through MRP II Roots; explain the background of ERP system, and expert systems; other ERP Challenges; 47

Information Management

• • • •

ERP Capabilities; explain the efforts made in creation of these systems; identify and discuss their advantages in business applications, and other ERP Hidden costs.

2.2 ERP-HOW DIFFERENT FROM CONVENTIONAL PACKAGES Conventional packages are very much confined and restricted. In a general term it is known as legacy system. The features are very less and a slighter possibility to explore. ERP packages are miles away from these petty things. It follows the backoffice and front-office concepts. The back-office job is to look after the raw material, financial issues, logistics and in brief internal matters. On the other hand front-office job-profile is to directly interact with customer. CRM is coming up as a front-office package. If we go into the depth of following figure, legacy system are very much condensed and compressed where as ERP system at the same time as compared to it are auto transactional, self helping, and mould itself in different crucial conditions i.e as a generalist and specialist. Figure 2, explains the comparison between the legacy and ERP systems.

Figure 2: Legacy system and ERP system

2.3 CURTAIN RAISER TO ENTERPRISE RESOURCE PLANNING SYSTEM ERP is not merely reengineering systems; it is reengineering the manner organisations accomplish business. In a recent CIO Magazine case study, Jeri Dunn, CIO for Nestle USA, said it this way, “If you weren’t concerned with how the business ran, you could probably [install the ERP software] in 18 to 24 months” (Worthen 2002). ERP is one of three enterprise-class applications, including Customer Relationship Management (CRM) and Supply Chain Management (SCM) that companies are deploying to automate business processes. ERP is focused on internal back office operation to external front-office such as financial system, human resources, inventory management, shipping, customer order processing and warehouse etc. (see Figure 3)

Enterprise Resource Planning System

Figure 3: ERP systems

2.4 BRIEF HISTORY OF ERP More or less any dialogue on enterprise resource planning (ERP) starts with material requirements planning (MRP-I) and Manufacturing Resource Planning (MRP-II) systems of the 1970s and 1980s. In the manufacturing environment of yesteryears, the artistic focus was on the competence to produce the product. This system integrates capacity, design engineering and management, costs, and long range planning of the enterprise into the equation. There are four stages to ERP.

•

MRP-I: Material requirement planning, which was nothing but a historical background of ERP, the motive, was only to tap inventory i.e. raw materials planning.

•

MRP-II: Manufacturing resource planning which looks after production related things. The concept of MRP II was to look after shop floor and distribution management activities.

•

ERP: Enterprise resource planning whose role is very wider and not confined to one department but have a broader purview.

•

ERP-II or MRP-III: Money resource planning or ERP-II advent can be seen few years after ERP system origination which more emphasize on planning of capital or when surplus money arises.

2.5 FORCES, WHICH MAKES ERP STRONG AND SUCCESSFUL There are distinguishing forces, which make ERP well built and flourishing. These are not confined to following but changed according to the circumstances. E-commerce: Without Internet and e-commerce ERP is like, a boat without rudder as there are many locations, which cannot be accessible by road so there is a need of wireless systems, which can efficiently be managed through Internet. Customer: Customer is vital for every vendor either it is fast moving consumer goods, or service oriented organisation like, insurance sector. Because if there could be no customer there would be no circulation consequently no selling, thus without customer ERP is useless. 49

Information Management

Enterprise: It is an appropriate place where it can show its potential. Financial infrastructure: ERP is not like a windows 98 package, if you won’t get the original one you can purchase the pirated from computer shop say in Nehru Place. It requires a planned fiscal setup. Figure 4 can make the picture clearer.

Figure 4: Four Forces, which makes ERP strong and successful

2.6 NEED OF ERP Conventionally, companies have created islands of automation. A hodge-podge of distinguishes systems that operated or managed a diversity of contradictory business processes. Companies have had analogous complicatedness with each new wave of information technology since the first mainframe systems. It takes years to apprehend some envisioned IT-enabled changes in organisational processes and performance, and there are many ways to fail along the way. An ERP can be defined as a coordination in which various functions of a company (accountancy, marketing, and production) are connected each others by the use of an information system centralized on the basis of a client/server configuration. It is regarding the integrated management system of a company, constructed on an integrated software package undernourished. The need of ERP can be elaborated and explained with the help of following question: • • •

• •

Why should we implement an ERP packages. Ans: We should implement an ERP package to get an edge over our business rivals. Will it significantly improve our profitability? Ans: Have you any doubt about its creditability? It will bring drastic change once you put the flavour of it in your organisation. Will it enhance our customer satisfaction level in terms of cost, delivery time, service & quality in totality? Ans: Take an example of pitcher when we go into the market to purchase it and if there could be any hole of very minute size say 0.0005 mm should we purchase it answer is no! So totality is like that, it would not be 99.9 % but absolute 100 %. Will it enable the organisation to reengineer the business process? Ans: Yes by changing the approach i.e. mindset of the people and office automation Will it permit the organisation to achieve the same business volume with reduced manpower? Ans: Yes because ERP is a process by which certain technologies and know-how can be incorporated and put into force, which can reduce and eliminate surplus or unwanted manpower thus results in reduction of cost and increment in profit

2.7 ERP COMPONENTS

Enterprise Resource Planning System

If your requirements go ahead of the capabilities of accounting software, and you find the prospect of implementing conventional ERP software overwhelming, you need ERP. All application modules share data through the ERP database, which contains the data for all modules. This is a new implementation of the old key database concept of entering data one time and then using it in all other processing. The world's finest easy-to-use ERP solution is fully web-enabled, seamlessly integrated and can be implemented in weeks. And it can computerize your complete operations globally. ERP can furnish assistance in accomplishing unimaginable efficiency of operations, significant cost savings, and maximize profits. ERP is packed with powerful features, tremendously easy to implement and use, comprehensive in its scope, modular and flexible, fully customizable, totally secure, and incredibly robust. It is the way companies will manage their businesses tomorrow. With ERP, you can assimilate transactions of any pulse of the entire organization, all the time. This drives costs number of your companyâ&#x20AC;&#x2122;s branches into one system. ERP can be completely webenabled and from any type of software on any platform, you can deal with your entire business by exception. ERP modules are a most excellent way to integrate all the departments. It is like a four-wheeler which can not shift single steps without its underneath, for ERP the underneath are its modules which sometimes also known as components. These modules enables all the employees of an enterprise to operate like CEO, giving them the tools, information, and insights they necessitate detecting problems earlier and taking action faster. To facilitate the easy handling of the system the ERP has been divided into the following core subsystems as shown in Figure 5.

Source: Adopted from Joseph. G. & Goorge. A 2002 Figure 5: The ERP Learning Community Framework

Finance: ERP takes care of complete financial accounting of the enterprise over the web. It maintains all the books and records that are essential for proper bookkeeping and accounting. All transactions affect and update the entire system, and the entire reporting is on the fly, for the most accurate information 51

Information Management

at all times. ERP helps you to manage all kinds of taxes, bank reconciliation and everything else that is required for efficient and complete financial accounting. Thus, financials provide real-time visibility into financial results, minute-byminute control over expenditure, and guidance for better decisions, b)

Human Resources: Handling Software for personnel-related tasks for corporate managers and individual employees of the organisation. Examples: human resources administration, automatic personnel management processes including recruitment, business travel, and vacation allotments, payroll handles accounting and preparation of cheque related to employee salaries, wages, and bonuses. Thus, human resources offers comprehensive HR solutions, from recruitment to compensation to work-force development

Manufacturing and Logistics: A group of applications for planning production, taking orders, and delivering products to the customer. Examples: production planning performs capacity planning and creates a daily production schedule for a companyâ&#x20AC;&#x2122;s manufacturing plants. Materials management controls purchasing of raw materials needed to build products.

Purchasing: Empower the Purchase function just like sales, indents, and orders. ERP covers all aspects of production, including issues quality control, material receipts, purchase invoices and production receipts, multiple bills of material. Thus, purchasing saves the time by simplifying and improving vendor evaluation, performance tracking and quality examination.

Production, Planning and Control: ERP enables you to plan for material requirements based on a production planning process. The system reports inventory requirements based on work orders initiated, stocks committed and existing stocks. Thus, PPC provides all possible reports and analysis, which facilitates in managing and keep good control of inventory.

Multi currency and Forex: ERP supports accounting for multi-currency operations, with exchange rate tables, transactions in any currency, accounting and reporting in all currencies, and accounting for forex gains and losses.

Business 2 Business (B2B): ERP is a virtual portal that can be accessed by customers, distributors, suppliers, and auditors. Anyone with a computer and a modem, and the necessary access permissions, they can place orders and monitor deliveries, and view account statements. To improve your service efficiency you can allow your business associates to manage their own interaction with your enterprise. All reporting can be individual, grouped, or instantly consolidated across the enterprise.

Funds Management: ERP enables you to manage funds efficiently. For each wing maintains your complete customer database and does kind of transaction type you may specify its effect on funds flow.

Marketing, Sales and Distribution: Helps to optimize all the everyday jobs and activities carried out in sales, delivery and billing. Key elements are: presales support, inquiry processing, quotation processing, sales order processing, delivery processing, and billing and sales information system. This module also includes a Point-of-Sale, which comes under retailing, can optimize the sales figures and also facilitate in having more delighted customers. Billing system with barcode label provides better reading, printing, quick billing and collections.

2.8 DISTINCTIVE WAYS OF IMPLEMENTING AN ERP

Enterprise Resource Planning System

A properly implemented ERP system can convey good results & dramatically enhance the aptitude to diminish costs, run leaner, and endow with good customer service. These are distinctive ways of implementing an ERP and following are the implementation approaches:

•

Phased implementation approach: This implementation approach is also known as Modular Implementation. The system of modular implementation goes after one ERP module at a time. This limits the capacity of implementation usually to one functional department. This approach suits enterprises that do not share many widespread processes across departments or business units. Independent modules of ERP systems are installed in every unit, while integration of ERP modules is taken place at the afterward stage of the project. This has been the most usually used methodology of ERP implementation. Each business unit may have their own ‘instances’ of ERP and databases. Modular implementation trims down the risk of installation, customisation and operation of ERP systems by reducing the scope of the implementation. The successful implementation of one module can promote the overall success of ERP projects.

•

Big-Bang implementation approach: This requires simultaneous implementation of numerous modules of an ERP packages. Enterprises outline a grand plan for their ERP implementation. The installation of ERP systems of all modules happens transversely the entire enterprises at once. The big bang approach has the prospective to condense the integration cost if it's executed methodically and cautiously. This method dominated early ERP implementations; it partially contributed to the higher rate of breakdown in ERP implementation. Today, not many companies dare to endeavor it anymore. The hypothesis of this implementation method is treating ERP implementation as the implementation of a big information system, which typically follows SDLC (Systems Development Life Cycle). But ERP is much more than a conventional information system because the implementation of ERP continuously calls for the realignment of business processes. Many parties concerned in ERP software systems are not IT professionals. ERP more than automates existing business processes and alter the business processes.

•

Process-Oriented Implementation: This method of implementation focus on the support of one or a few critical business processes, which involves a few business units. The initial customization of the ERP system is limited to functionality closely related to the intended business processes. The processoriented implementation may eventually grow into a full-blown ERP system. This approach is utilized by many small to mid-sized companies whose business processes are not too complex.

•

Vanilla implementation approach: In another implementation approach that focuses on minimal customisation of the ERP packages.

2.9 GUIDELINES FOR ERP IMPLEMENTATION 1)

Understand your corporate needs and culture: An ERP implementation will bring a change in the roles of different departments and responsibility. In short, it will result in a change in the existing power structure.

Information Management

Complete Business process Change: ERP can change the whole outlook of business by fully reengineering it and giving it new shape and direction, which could be unimaginable.

Provide strong Leadership: Leaders plays a very vital role in making a destiny of followers, so while selecting a team leader/project leader, this point has to be kept in mind.

Choose a balanced team: The system environment of today’s ERP solutions is complex: RDBMS, servers, networking, LAN, WAN, etc. There will be no longer a lot of documentation to specify the requirements. These will be on-line, as an integral part of the package. So the team should be balanced in order to rectify the error.

Selecting a good implementation methodology: It is advisable for the project leaders to set out clear and measurable objectives at the very beginning and review the progress at intervals, as the implementation progresses.

Train every one: Since this ERP package is not confined to specific people but a beneficial to whole organisation so as far as training part is concerned it will be given to all and not restricted to few as it is indirectly going to benefit the organization alone.

Commitment to adapt and change: An ERP implementation should not look upon as a short distance run. It’s an on going process. It has wide implications, and will impact the future of the company for many years to come.

2.10 PRACTICALITIES IN AN ERP IMPLEMENTATION a)

Inner Practicalities: The key practicalities in an ERP implementation are the internal preparation. Whether or not a project is successful, depends to a noteworthy extend on an adequate amount of internal preparation.

•

Be acquainted with your necessities: Nobody knows your business better than you accomplish. Before calling in vendors, the groundwork within the enterprise is vital. This will not only get geared up to appraise the vendors and applications more effectively, but will also facilitate the enterprise to get better utilisation of any system. Fundamental Point: Distinguish all problem areas in the current work process and list transaction that seem to entail special processing from the general process, sales invoices that can not be traced to a sales order, which could pose a trouble in certain types of businesses. Test out the prospect of simplifying procedures and identify areas of duplication of effort. Assemble user complaints of the existing system and categorize them accordingly into sales and purchase. This could be valuable source for evaluating alternative systems. Accumulate information regarding the requirements for reports at various levels of management. If the operations are extend across a region or are global, it has to be considering using one system at all locations, and vendor should have the proficient of supporting the company at all locations. The present hardware infrastructure obtainable has to be checked.

Outer practicalities: The new economy and the extended enterprise are the key external factors that have motivated and sometimes pushed some companies to implement an ERP system. A psychological effect also plays an important role on the ERP implementation, where a company takes a decision driven by the phenomena and not necessarily by its own needs.

2.11 OPTIONS FOR IMPLEMENTING AN ERP SYSTEM

Enterprise Resource Planning System

Flexibility means nothing but customisation. Say there is one institution XYZ Management College that is a pioneer name in the field of academics and now it had expanded into the FMCG business and the ERP package implemented is BaaN IV ERP software. At this juncture, flexibility with respect to this is that, it is the single software, which can deal with both the manufacturing organisation and academic institution. Centralisation: It could be so much centralised that all the departments are streamlined and decisions will be taken from one place. X- Axis => Centralisation Y- Axis => Flexibility Case-1 High Centralisation- Low Flexibility Case-2 High Centralisation- High Flexibility Case-3 Low Centralisation- Low Flexibility Case-4 Low Centralisation- High Flexibility

2.12 CONQUERING IMPLEMENTATION OF ERP Enterprise systems are all about the enterprise and not about systems. Its success greatly depends on the responsibility of top management and active participation of the HR people. The popular notion is that implementation of an ERP is a technology decision. In fact, it is a decision that preferably should be based on business needs and 55

Information Management

benefits. The success of an ERP solution depends on how quick the benefits can be reaped from it. This necessitates rapid implementations, which lead to shortened ROI periods. Traditional approach to implementation has been to carry out a Business Process Re-engineering exercise and define a “TO BE” model before the ERP system implementation. This led to mismatches between the proposed model and the ERP functionality, the consequence of which was customisations, extended implementation time frames, higher costs and loss of user confidence.

•

Implementation strategy and approach: Organisational readiness and preparedness is what makes the key difference between success and failure. Any ERP implementation brings a transformation in varying quantum; hence, senior managements commitment to change management process and piloting the ERP implementation becomes completely necessary. Over a period of time, the additional functionalities that are available in the ERP can be implemented and by that time, the organization would have tasted success of the implementation. The end-user participation and ownership of implementing the ERP is a notable paradigm shift compared to the conventional software development process. Implementation strategy is context dependent. So what is successful in one company may not yield similar results in another organisation. Therefore, the strategy and approach to implementation is a key enabler for successful implementation.

•

Start up education: The simplest and most cost effective education method is to set up either a 2-day corporate training in the company or at a convenient local venue.

•

Continuous communication: The success of the ERP initiative, on the softer side, can be accredited to two things, first, in all the communication about the project, a exercise of tying central messages and specific department objectives and needs back to the overall company. Second, a habitual mix of efforts to include everything from conducting workshops, publishing newsletters and holding focus groups to organising lunch time discussions and traveling road shows each designed to suit dissimilar stages across the implementation life cycle.

•

Forming the team: Selecting the right project leader is as important as selecting the right package. Core team leadership is a full time assignment. Team leaders should know the business well and have cross-functional experience. They should also be politically savvy, have credibility within the organization and be good communicators, and, of course, be from the business side and not the IT management. The team is also as important as its leader. The apex management must make sure that the best and the brightest join the team.

•

Project planning: An important task is the preparation of detailed plan that covers the total implementation process. Here various project management techniques like PERT charts can be used. The implementation plan should have clear components and should include the time schedule, ownership and responsibility, resource requirements and critical success factors for each phase. The milestones are as follows and thus may be included in project plan that is Training of project team members, Mapping of business onto the software, Function-wise implementation, Customization, Uploading of data, Tests run, Parallel run, Crossover, etc. IT projects are essentially systems integration projects. They are complicated and require attention on issues such as the implication of even the slightest change. The project planning should also lay emphasis for determining the effort (in man-months manhours) required for carrying out the various activities. It is important to: (a) scope the project, (b) estimate the step-wise and task-wise man-hours required, and (c) preparing a schedule. These all will lead to project plan

preferably using project management tools like network charts, project management software, PERT/CPM.

2.13 DYNAMICS THAT SHAPE THE PRICE TAG OF ERP You don’t have to be a specialist to be acquainted with that, ERP is one of the most precious technology initiatives that an enterprise can implement. While it is very intricate to endow with global costing guidelines, there are some vital considerations that can smooth the progress of you to guesstimate your total expense for implementing ERP. Here is an overview of four cost dynamics associated with staffing during an ERP implementation. These dynamics will likely weigh into your decision about whether you should purchase a packaged ERP system from a vendor or if you should custom fabricate an ERP solution in-house.

•

Dynamics A- Plan for human costs: The costs of installation, implementation, and data migration generally run about three to four times the original cost of the packaged ERP software. For example, if your software costs $2 million, you can expect to pay an additional $6 million to $8 million for consulting services to get the system into production, which sometimes considered as hidden costs.

•

Dynamics B- Consider remote consulting: If your organisation is located in a major metropolitan area, you will likely have lower consulting costs. For example, an ERP project in Jamnagar, Gujarat may cost double the rate of the same system developed in Los Angeles. This factor is here because the rates are more steady and competitive in larger cities. Organisations located in smaller cities may have to compensate their vendor for consulting services at a rate much higher than the market average. If your company is located in a smaller city or rural area, you may want to use off-site consulting and hire consultants who work from home.

•

Dynamics C- Transition your IT staff: In a recent survey it had been determined that end-user adoption of an ERP package was the greatest anxiety among IT professionals. Analysts authenticate that training end users is a noteworthy expense. In a recent report on SAP end-user training, Gartner suggests that, at a minimum, enterprises should allocate 17 percent of the total cost of an ERP project to training. Gartner research also establish that companies that budget less than 13 percent of their costs for training are three times more likely to see their ERP projects run over time and over budget when compared with companies that spend 17 percent or more on training. But end users aren’t the only staff members who should concern you. Staff turnover among developers is common in organisations that are implementing an ERP solution. If you desire to purchase a packaged ERP solution, be prepared for staff turnover. In many cases, programmers will be excited to learn a new technology, while others are reluctant to clinch change. On the average, IT managers can anticipate to lose up to 40 percent of their IT staff, primarily those programmers who are unwilling or powerless to master the new software.

•

Dynamics D: Avoid the illusions of false savings: Many managers choose to purchase a prewritten ERP solution under the hypothesis that because the software is prewritten, they can rationalise their IT staff. In reality, prewritten packages require IT personnel to locate bugs and apply patches to the packaged software. There are seldom any real human savings associated with adopting a prewritten ERP package. In practice, your IT staff will stay behind about the same size, with your old programmers being replaced with application specialists. 57

2.14 ERP BENEFITS The ERP system has an enormous payback and it is 100 times better than a conventional packages. Some advantageous features of ERP system are: Communication with Suppliers/Customers can be automated, efficiency is aided by reduced manual entries, dependency on human resource eliminated, integration of all function already established, readymade solutions for nearly all the problems, supplier and customer can intermingle on-line at any time, reach multiple locations through one system, complete integration of systems across all functions, pace in transmission of information etc. The few other elaborated benefits are:

•

Automatic Updation to new Technology: ERP systems can automatically update itself according to the new technology.

•

Enhanced flexibility: ERP is multi-module application software and is very flexible and frequent, e.g., production manager can access ample number of information through his lap-top of marketing department by sitting at his home.

•

Improved customer satisfaction: with the help of ERP, customer have an individual login name and password and they are able to solve their grievances by Internet alone specifically no need to waste time in visiting personally.

•

Information Technology: Reduced support costs. Reduced infrastructure costs.

•

Lead-time minimization: “time gap between ordering the goods and its delivery is known as lead time” so if this could be minimized then there will be reduction in inventory cost burden.

•

Process Improvements: Eliminate redundant transactions and multiple reconciliations; extra efficient job rotation process; more efficient staff and succession planning.

•

Related initiatives: Better focus, reduced spending.

•

Strategic Direction: Improved resource allocation, More flexible organisation, and better future decision making.

2.15 CUSTOMERS EXPECTATION IN ERP PACKAGES Expectations in ERP packages are a birth right for customer as they are a going to be the owner of the product. The customers have to be very cautious and imagine a lot while finally locking the product. The expectations they use to have regarding the product is elaborated and explained one-by-one.

•

Financial health of the company: Implementation of ERP can give an organisation a new shape that is more emphasize on the financial status, so the organisation awakes about that whether they are moving towards southward direction or in a northward direction.

•

How big the company is and whether its main focus is implementation alone? ERP’s user’s total strength and size plays a very vital role while considering all the factors as vendor’s core benefit is not only to emphasise on implementation and go out, but to build long-term relationship in order to tap more business i.e., after sales service, more implementation at different places.

•

How easy/fast is it to get skills on the package? Again this is a question, which varies from company to company and also depends on the level of highly skilled and technocrats employed by the organisation thus whole effort is required by user itself.

•

Is implementation of the package easy: This is something, which can not be answer in one word i.e., yes /no it is amazing which requires cooperation from user as well as vendor? So it will be an easy job if you are serious and toughest when you take it lightly.

•

Is the package compiled: It covers all areas of the department starts from production then marketing, purchase, research and development and many more, specifically it has to be very exhaustive.

•

Is the package localised: Now, the million dollar question is about the SAPAG which is a German based company and has a corporate office at that place alone and if somebody keen to purchase a package who resides in India what strategy the SAP is going to follow as far as service part and other up gradation issues are concerned.

•

Is the package too old or too new: This includes many other things and gives answers to a lot of questions like latest trends, present platform, also its competency like Y2K compliant? VAT ready etc.

•

Number of implementations in the country: More the implementation more the experienced ERP vendor are, consequently leads to better after sales service and grasp market share. Take an example of Tally or other financial package such as wings, Accpac, etc. when we actually go for purchasing why we give priority to tally answer is only due to its market share and ample number of implementation.

•

Quality of the consultants hired: Consultant whose role basically is to bridge the gap between the vendor and the user as a liaison, however same time consultant job is also to provide training, giving knowledge to both user and vendor about the latest trend and also guide them about the in-house development of ERP or purchasing from outside.

•

Who is supporting the package: Under whom banner the package had been explored, are they the brand name or a layman in the field of ERP. If they are new player what USP’s they have followed so the user can be extracted like Oracle- master in production module, but the new player come-up with R &D module which no other vendor have.

Enterprise Resource Planning System

2.16 STUMBLING BLOCKS ERP System, though a boon to the corporate world is again not foolproof. However, this system suffers a number of problems including:

•

Confusing and difficult: ERP Softwares are a gigantic package and consists of numerous modules, so it is very difficult to understand its characteristics but once you understand it becomes easier to work.

•

Customisation is costly: Customisation is obviously costly, for instance when report is needed to configure, one person expected from the ERP vendor‘s side has to come and give support. Hence more the customization /configuration greater should be the service cost charged by the vendor.

•

Customisation is time consuming and in many cases impractical: ERP is not a one or two day job it is a regular process it requires years to complete as many things have to be incorporated into it i.e. mindset, office automation, etc. There is clause of hidden cost, which always pinches the user.

•

Decline of an individual’s monopoly over information monopoly: As information can be put into the server and rights and authority can be given to appropriate people who can access it so that production department data cannot be confined to production department people. It can be shared by marketing department people with the help of login name and password thus cutting short time and reducing paper work.

•

ERP engenders a host of fears: It engenders a host of fears on some of them are Job Redundancy. There is misconception among the employees that ERP can be a threat as for upcoming employment, this is not absolutely true because the persons who are not working hard have to be more cautious as performance appraisal chart is regularly maintained and monitored. Therefore, for people who take no pain there is no gain.

•

Geographic Restriction: The ERP packages are readymade packages made by the ERP vendors and can be customized according to the user need, thus sometimes not suits individual persons who are geographically away.

•

Implementation of an ERP project is a long process: Like customisation implementation is also a long process because there is ample number of departments and ERP can come in full-flow when the entire department should be fully compatible with ERP integration.

•

Platform restriction: Platform restricts could be the another obstacles upto some extent as they are using different operating systems.

Major stumbling blocks take account of the technical issues around providing adequate and protected access to ERP from heterogeneous locations and platforms.

2.17 ERP SYSTEM ACCOMPLISHMENT Though ERP systems suffer from certain drawbacks or rather we can say certain obstacles but its merits supercode it demerits. Few accomplishments, which motivate ERP to follow the 24x7 culture. While ERP systems are generally the most expensive institutional information system implemented by most institutions over recent years, 61

Information Management

they are not alone. At most Universities there are other information systems filling organizational needs that ERP systems do not address. Course management systems (CMS), such as WebCT and Blackboard, are usually the next most expensive and farreaching example. Other institutional information systems may include: timetable management software, assignment tracking software, bookshop management software, library catalogue systems and various infrastructure systems such as student and staff authentication. While the label of this paper mentions ERP systems, the basic premise of this paper is that a gap exists between the functionality of all institutional information systems and the needs of the staff and students. The few USP’s of ERP systems are: 1) 2) 3) 4)

Web-based student records: Provides staff with access to student records data including course lists, student photos, and student enrolment details. Timetable generator: A web application that allows a student or staff member to generate a personal timetable. Minimum course presence: The provision of a consistent minimal web site for every course offered by Infocom independently of academic staff and as early as possible. Informal review of grades (IROG): Web-based processing of student requests for an informal review of a final grade.

2.18 STEPS FOR AVOIDING PITFALL An ERP system will perhaps be one of the prime investments you will make, so it's critical to the enterprises to do it accurately. The worst thing you can do is most often by picking the wrong software, make a team to undo the mess, and then relocate for a correct “aim”. We have all read the horror stories of enterprises that acquire implementation decision in haste by initially purchasing software before they were ready.

•

Classify the Methodology: Choose on and stick to a lucid, analytical methodology. The methodology should guide you through each step in the selection process and diminish the emotional proportion in the selection. The processes include distinctive phases for completing a thorough business-process review; evaluating vendors; managing software demonstrations; supporting the eventual decision-making process; and structure the supporting implementation plan, together with costs.

•

Plot to Business Processes: Don't start with software demos. Begin with your business processes, and then map out your feature/function requirements through a series of business-area reviews, the creation of process maps, an assessment of "to be" process changes, and the development of a requirements matrix with supporting business scenarios.

•

Be conscious of Organisational Chemistry: Use your instincts when it comes to the organizational chemistry between your enterprises your consultants, and your selected vendor. You want a consulting organization that you sense relaxed with, one that can extract the input it needs from your in-house team members. Be on the watch out for a solution that sounds too trouble-free or will be done in a month. You are making a critical decision this has to be taken into consideration always.

•

Elect to choose a well-built Team: Set up a steering committee with the president or CEO and heads of sales, finance, and operations, and sanction them to make decisions.

•

Scrutinize Potential Vendors: Accomplish a rigorous software-selection process, and situate potential vendors under the microscope. Think about more

than just features and functionality a financial stability, technology strategies, long-term support, implementation successes, and corporate culture, are key factors. •

Appraise Business Processes: Be equipped to alter some business processes if you want to minimize or eradicate customization. Even the smallest enterprises have to make process compromises in their final solution.

•

Bargain Customisations: Negotiate all of your customisations before signing a contract. If you do have to customize, you want to be acquainted with up front what it will cost and more important discuss about hidden cost and then incorporate that as part of your contract.

•

Modernize Infrastructure: Plan for an infrastructure improves to sustain the new system. Some ERP implementations require the redesign of your network; make sure you identify what you require to do and how much it will cost.

•

Predict Elaborately: Elaborately look after your implementation plan. The goal is to foresee now, to eliminate implementation setbacks in terms of both cost and time. Implementation will always be preferred or rather become mandatory with the Vendor team i.e., make convinced that your software vendor has a role in your implementation. The software vendor has the most vested interests in making clear-cut that you are a pleased customer.

2.19 SUGGESTIONS TO AN ERP VENDOR Deciding by the vendor to supply ERP software is probably the most complex decisions in the whole ERP Project, so you have to incorporate the following point in mind as ERP Software being so expensive, one cannot manage to pay for to make mistakes and correct it later. They have to be very particular in taking decisions, that is, who are the key man and whose benefits are addressed. No doubt that ERPsoftware is a foremost requisite for a big corporate explicitly who are going to implement it in a near future. The suggestion to ERP-vendor is that they could bestow much emphasis to make their product qualitative, competitive and price effectual rather than contemplate in selling because automatically the sale would come to them once the product is acceptable. Key suggestions that have to capture into account are:

•

Try to sell products in module wise and according to need: Specifically, if the concern is marketing oriented then force to sell the marketing module of ERP first, if production oriented then the Inventory Module.

•

MoU (Memorandum of Understanding): Some MoU or issue base alliance is required between the two or more organizations, in order that in short span of time they can be able to fabricate quality product and attract customer. Like sharing of R&D (Research & Development) lab and many others overlap work so to make the product more competitive and cheaper as well.

•

Try to cut-off the existing price With the intention that vendor inclination is on selling multiple numbers of copies and attain a market share i.e., they will try to sell more licenses.

•

Installed that portion of module which required utmost: Generally full fledge installation requires years to complete so it is advisable both to vendor and user to installed that portion of module which required utmost. Like, HLL is a FMCG their core area is marketing and selling so they walk off for sales and marketing module first.

•

Proper implementation of an ERP project: Proper implementation of an ERP project is the most crucial activity in the life cycle of an enterprise. This requires careful planning and teamwork. 63

2.20 FAQ- FREQUENTLY ASKED QUESTIONS FAQ-1: Explain what problem the company will face if they develop ERP package in-house. Soln: ERP packages are software-integrated packages with ERP concepts. ERP vendors generally develop ERP packages. Developing ERP package in-house will let a company to face major problems of cost and time. Developing in-house ERP packages is very complex, time-consuming and extremely expensive. Developing packages is the headache of the ERP vendors. They are specialised at such works and they have made developing packages their own business. Any organisation should concentrate on its own products and its better quality rather than wasting time and money on developing ERP packages. Developing ERP packages should then be left at the disposal of the ERP vendors. Thus, in house ERP packages require much resources and time and moreover its failure may leave the company out of business. So taking such a big risk must always be avoided because it may create a major problem in the business environment of the company. FAQ-2: What Makes ERP different? Soln: Traditional computer information systems used by many businesses today have been developed to accomplish some specific tasks and provide reports and analysis of events that have already taken place. Example is an accounting general ledger system. Occasionally, some systems operate in a ‘real-time’ mode that is, have up to date information in them and can be used to actually control events. A typical company has many separate systems to manage different processes like production, sales and accounting. Each of these systems has its own databases and seldom passes information to other systems in a timely manner. ERP takes a different approach. All applications access common data. Real events in the business initiate transactions. Accounting is done automatically by events in sales and production. Sales can see when products can be delivered. Production schedules are driven by sales. The whole system is designed to be real-time and not historical. ERP structure embodies what are considered the “best business practices”. A company implementing ERP adapts it operations to it to achieve its efficiencies and power. The process of adapting procedures to the ERP model involves “Business Process Re-engineering” which is a logical analysis of the events and relationships that exist in an enterprise’s operations. FAQ-3: What types of people become ERP certified? Soln: A wide range of people chooses to follow the ERP certification for a variety of different reasons. In short, almost anybody who works in or around the ERP industry may choose to become ERP certified. Some common types of people that choose to become ERP certified include: • • • • •

Authors and Journalists Consultants ERP Team Members Implementers Senior Executives

• • • • •

CEOs End Users ERP Trainers Programmers Students

College Teachers ERP Sales Personnel Functional Managers Project Managers Help Desk Support

2.21 CUSTOMER RELATIONSHIP MANAGEMENT Preserving existing customers and providing improved services to expand the loyalty is termed as CRM. The rationale that business exists is their customers. Developing rapport with customer and supervising it resourcefully with the intention that it is valuable to both the customer and the business is an imperative goal. CRM facilitates business in accomplishing this goal. In today’s marketplace winning and sustaining muscularly built customer relationships can make the 64

difference between success and a failure. Faced with global competition and short product lifecycles, organisations require making accessible their customers with the topmost possible standard of service to keep hold of business. This means knowing the customerâ&#x20AC;&#x2122;s needs, preferences, buying history and potential future purchases. CRM is software, which facilitates an organisation to oversee its customers healthier. Company might have a database about its customers that make available information about them in great multiplicity. With the assistance of CRM software, sales people and service representatives can access this information and bestow with customers with customised service as per customer needs with sky-scraping attitude to product plans and offerings, jog the customers about service requirements, identify what other products a customer had purchased, and so forth. CRM can also be web enabled thus adding greater value to the entire progression. CRM (Customer Relationship Management) applications smooth the progress of the capture, consolidation, analysis, and enterprise-wide dissemination of data from existing and potential customers. To build up the full benefit of CRM, it must be seen as combination of people, process and systems rather than just IT application. Customer relationship management (CRM) is the most talked about of the three enterprise applications that are the focus of this unit. As the economy remains lethargic and customers remain cautious, the need and aspiration to get closer to customers are the primary means of differentiation in the marketplace.

TES integrates customer information and transaction data. Implementing TES requires high level of integration with legacy systems and disparate hardware systems. TES has three sets of component building blocks. a) The first building block customer information. This information is situated in company databases and manipulated either by legacy or ERP systems. b) Companies should have infrastructure of systems like telephones, faxes, personal computers and other devices, in place that would allocate company to communicate and demeanor business with customers. c) Finally the third is a set of advanced applications, often specific to industries. b) Call centers: Call centers are playing an increasingly significant responsibility. They are emerging as main point of contact, providing service to customers, business partners and employees. Call centers execute the following five functions: a) Engender reports for root cause analysis. b) Formulate recommendations to customers concerned with the product/service which suits the customer needs. c) Make available more information about product and services. d) Obtain calls and monitor progress on customer requests and problems. e) Resolve issues or refer problems to subsequently level of service. Call centers have the ability to be linked with voice, video and data together. Illustration of Polaroid is exceptionally interesting. Polaroid has an after sales service call center in Scotland. Customers across Europe can call into that call center. The computer identifies the country of incoming call and routes the call to representative who speaks that language. c) Internet telephony protocol: This allows customers to speak to the customer representative at the call center while browsing the company’s web site. The customer can contact the call center simply by clicking a hyper link. At the other end the call center agent can pull information about customer’s history, products, previous service calls if any. d) Better Field service: Companies can make available better field service using call centers. Call centers can forward customer complaints to representatives in the field. Enabled field service sales representative can get up-to-date customer and product information via Internet. Sales representative can get information about product designs and repair manuals. They can ensure outstanding customer queries, service calls, and customer history all while in field. Customers can not only download product documentation but also communicate with other users. It has as database that can provide answers to questions. e) One to one marketing: One-to-one marketing means that business knows’ each customers tastes and preferences allowing companies to customize customer visit. 66

By providing a personalized experience to customer you can accomplish better customer service, retain customers and develop lasting relationships. Amazon is one such example. Amazon knows its customers reading tastes and suggests books that meet up that interest. CRM software facilitates companies to accumulate, retain, and analyse information about individual customers allowing organisations to accomplish this. Call centers and internet make it easy for companies to correspond with customers. It makes easier for them to track buying behavior and keep hold of customers.

Comparative study between ERP and CRM Since ERP and CRM both talks about integration and both are enterprise oriented, still there are some discrepancies. The comparative study can make the picture clearer by Comparing ERP with CPM. ERP: Enterprises conventionally focus on processes and technologies, with purpose of optimizing these processes using MRP and ERP systems. The focus was always inward. CRM: With Enterprises becoming more customers oriented, they are realizing the benefits of including customers and business partners in the value chain. Enterprises are becoming more externally focused. ERP: Enterprises use ERP systems to integrate and deal with distinguish operations and process. ERP system integrates functions like Accounting, Human Resources, and Inventory Control to give an integrated enterprise. CRM: CRM Enterprises have started to realize the ‘value of strategic extensions’ like Supply chain management and Customer Relationship Management applications. These softwares enable companies to amalgamate. ERP: Enterprises are replacing materials requirement planning with supply chain planning software as it enables companies to generate optimal plans for producing, delivering goods through collaboration. CRM: Companies are integrating CRM software and other Internet based applications with ERP packages to create what is being termed as ‘Extended enterprise’. ERP: ERP systems handle core information related to company’s business, customers, products, orders and employees and financial data. Extended enterprise allows the company to share this single source of information with all relevant parties. ERP can reach out suppliers and customer by means of Internet. CRM: Applications like CRM and supply chain planning provide enhanced functionality. Incorporated ERP & CRM Simultaneously in an Organisation The major purpose behind jointly going for CRM and ERP is that, customer interacts with companies through variety of channels like phone, fax, mail, email, web sites, and wireless devices. Ensuring quality customer service and providing consistent information is main challenge for business. CRM packages can facilitate companies to consolidate information across dissimilar channel and present consistent information, irrespective of channel. The permutation and combination of ERP and MRP has helped organizations congregate data over years. Data collection isn't enough. It must be properly applied. CRM, Internet and technologies have created endless opportunities for tracking, leveraging this data tied up in ERP systems. CRM Integration Points: Companies are suitably customer oriented. Providing excellent customer service and timely response is no longer a matter of preference but 67

Information Management

a necessity for business. The winning businesses will be those who can delight customers and work together with business partners. CRM solutions assist companies to accomplish these objectives by leveraging the power of Internet, networking and ERP system and building a effortlessly integrated enterprise. The following Figure 8 can give a clear picture. Companies look forward to extend their capabilities by the two approaches:

•

Best-of-Breed Approach: They can use best-of-breed approach tying CRM, SCM software provided by different vendors to their core ERP systems.

•

Single vendor Approach: Else, companies can take a single vendor approach, implementing required systems provided by existing ERP vendor.

Figure 8: CRM is more than software

2.22 SUPPLY CHAIN MANAGEMENT Supply chain management (SCM) helps businesses to enhance and understand the activities that endow with component level material for their finished product. For example, in the retail sector, wholesaler relationships are vital, and in the automotive industry, part supplier relationships can influence the manufacturer’s capability to construct a car on time. By focusing on SCM, corporations can significantly get better operational efficiency. SCM seeks to help businesses control costs by uncovering the difficulties in their key relationships (e.g., with internal suppliers and external vendors). The fundamental matter is the necessity to understand customer demand and bring into line it with the supply side of the business. By doing this, organizations can condense or even prevent costly overruns and/or product shortages. SCM software achieves these outcomes in a diversity of ways and a variety of implementations. Fundamentally, SCM links suppliers to databases that show forecasts, current inventory, shipping, or logistics timeframes within the customer organization. By giving those suppliers such access, they can well again meet their customers’ demands. For example, the supplier can adjust shipping to make certain that their customers have the inventory necessary to meet their customers’ needs. Suppliers can download forecasts into their own manufacturing systems to automate their internal processes as well.

Figure 9: Supply chain management

Collaborative research on ERP integration with SCM Implementing new software into your company's core businesses processes is a painful modus operandi. In the early 90's, ERP came of age. One and all had to have the functionality ERP packages promised. Since then, as Web and Internet technologies have matured, ERP packages on the front end, and Supply Chain Management packages on the back end, these packages have come into their own. One of the most enduring instructions of the mount and collapse of the dotcoms was their breakdown to recognize the magnitude of sound Enterprise Resource Planning & Supply Chain Management. The capability to deliver on time is perhaps the only differentiator between companies in an arena where the competitor is only a mouse click away. ERP is one such vicinity, which has revolutionized business environment from underneath to pinnacle. Information shows that fortune 1000 firms have or will install ERP system, which will boost the global ERP market from 675 billion to 2250 billion rupees, over the next 5 years. So far, ERP sounds like a great idea. Yet, switching to an ERP system is a bit like constructing a new-fangled residence to replace an aged cottage. You know you necessitate it, and you can envisage how much more functionality the new residence will have, but the aged cottage is paid for and hard to give up. In addition thereâ&#x20AC;&#x2122;s bound to be interference during the constructing process and of course some surprises along the way. Victory in todayâ&#x20AC;&#x2122;s manufacturing environment is no longer measured merely on the basis of how proficiently your plants can manufacture products. Rather, success is increasingly measured by how effectively and efficiently you can consistently congregate customer requirements. Meeting those ever-changing requirements demands the greatest enterprise solutions for your business â&#x20AC;&#x201C; solutions built for manufacturers, by experts who understand manufacturers. ERP with SCM recommends a established enterprise software solution, optimized on and provided specifically the proper platform. The solution offers deep functionality for manufacturing execution and the other areas of a manufacturing.

Figure 10: Pictorial presentation of ERP and SCM functioning

Importance of ERP in SCM Traditionally ERP tools were not considered for SCM and resultantly, the information flow between various members of the supply chain was slow. This was because until the late 1990's the concentration of organizations was on improving the internal efficiency alone. Therefore, ERP systems also supported only such functionalities and the systems across the supply chain were disparate. The organizations however, soon realized that although internal efficiency is important, its benefit would be limited unless complemented by increased efficiency across the supply chain. They also realized that, faultless flow of real-time information across the supply chain was key to success in the emerging market scenario which was characterized by galloping advancements of technology, shorter product life cycle's etc. Therefore, organizations started integrating ERP applications with SCM software. This ensures that the efficiency was achieved across the supply chain and there is a seamless flow of information. ERP in such state of affairs, becomes a vital link in the integrated supply chain as it serves as the integrated planning and control system. In summary, ERP applications help in effectual SCM in the following ways:

â&#x20AC;˘

Share data: They can create opportunities to share data across supply chain members, which can help managers in making better decisions. They also make available wider scope to mangers of supply chain by making available much broader information.

â&#x20AC;˘

Real-time information: ERP systems can provide real-time information, which can be great help in supply chain decisions. For example, ordering raw materials can be based on the inventory details provided by the ERP systems.

Web-enabled ERP and its impact on SCM The web-based technologies have revolutionized the way business is carried on and supply chain management and ERP are no exceptions. In order to leverage the benefits offered by this new technology enabler, ERP systems are being "web-enabled.'' Internet allows linking of the websites to back-end systems like ERP and providing connections to host of external parties. The benefits of such a system are that customers have direct access to the suppliers ERP system and the vendors in turn can provide real-time information about inventory, pricing, order and shipping status. Internet thus provides an interface between ERP system and the supply chain members allowing real-time flow of reliable and consistent information. To illustrate a benefit of web-enabling ERP, such a facility allows customers to go on-line and configure their own products and get price information and immediately gets to know whether the configured product is in stock or not. This is made possible, as the customer's request directly accesses the ERP system of the supplier.

ERP vs SCM The difference between ERP systems (e.g. SAP, Baan, People soft) and SCM systems has been subject to extreme debate. One of reasons for the same is that the ERP vendors are adding additional SCM functionality to their products while SCM vendors are also expanding their functionality, encroaching on the area handled by the ERP vendors. With the vendors of ERP systems and SCM systems adding new and more functionality, the divergences between the same have been distorted. For example, major ERP vendors are introducing advanced planning and optimization as an integrated component (also a component in SCM) of their system. In the following table, let us try to understand the main discrepancy between ERP and SCM systems at the moment available.

2.23 SUMMARY In the world of networked markets, to be innovative, one needs not only to think out of the box, but also think more importantly about reaching equilibrium. ERP Systems helps organizations to maximize their growth & potential. ERP suites can improve and update corporate resource management, but the training and costs involved can be high-priced. ERP is one such vicinity, which has revolutionized business environment from underneath to pinnacle. If you throw a little light on the Figure 11 there is an elephant, which had been compared with ERP system. Purpose is that ERP had got so much height + solidity+ depthness, which in general elephant possess. And whatever functions you are imagining you will search out by a click of mouse.

Figure 11: ERP is like an elephant

ERP deployment, management, and evolution are significant operational concerns in today’s cost conscious business atmosphere. The performance of enterprise applications designed to streamline ERP processes and operations is dependent on the fundamental network infrastructure. Companies should take a holistic view of their mission critical application, networking environments and include best-in-class networking solutions. Enterprises have long made flamboyant statements about getting closer to their customers and streamlining operations. The ERP, CRM, and SCM applications and the organizations implementing them are at slightest in part, “bringing teeth” to those superior intentions. It is not a trouble-free process, though. In reality, the extremely publicized failures of these initiatives have in some minds polluted these applications and their possible benefits. However, more and more organizations are moving ahead with these initiatives, and the successful organizations will gain from higher margins, better customer relations, and improved back office operations. Organisations are only paying attention in deploying tools and applications that have a quantifiable impact on customer relations, supplier relations, and internal competence; this unit outlines three such tools. The future role of ERP systems may be far more decisive than the reasons for which they have conventionally been adopted. With the speedy emergence of wave after wave of new-fangled technologies, the accessibility of an effectual infrastructure on which to build may be one of the most important factors that facilitate and uphold future competitive advantage. Moreover, the lessons learned in the process of establishing this architecture may be invaluable in 72

concrete manner for technological innovations to move forward. This work has attempted to illustrate that the benefits of ERP systems, beyond well-documented subjective evidence, are rationally rooted in this theory.

3.0 INTRODUCTION In todayâ&#x20AC;&#x2122;s fast-changing global markets, success is no longer tied to the traditional inputs of labour, capital or land. The new critical resource is inside the heads of employees: knowledge. What a company knows? and how it leverages that knowledge into knowledge management for its use in the organisation. The individual technologies are not in themselves knowledge management solutions. Instead, when brought to market they are typically embedded in a smaller number of solutions packages, each of which is designed to be adaptable to solve a range of business problems. Examples are portals, collaboration software, and distance learning software. In this unit we are aiming at imparting knowledge about this knowledge management and how to use different tools and technologies to achieve the objectives of an organisation. Business Analytics and Business Intelligence are concerned with the process of collecting and analysing domain-specific data stored in data warehouses to derive valuable insights about customers and emerging markets, and to identify opportunities as well as key drivers to business growth. It is increasingly being seen as the key differentiator that provides a competitive edge to companies across industries. The tools used in Business Analytics are varied. They range from simple slice-and-dice tools to statistical methods such as log it regression, discriminant analysis and multivariate analysis, to more sophisticated tools such as neural networks and optimisation. The application domains are equally varied. How companies, banks, 76

insurance companies and airlines have all been beneficiaries of Business Intelligence is what we are also going to discuss in this unit.

3.2 KNOWLEDGE MANAGEMENT IN ORGANISATION Knowledge management (KM) is the management of knowledge within organisations. A widely accepted ‘working definition’ of knowledge management applied in worldwide organisations is “Knowledge Management caters to the critical issues of organisational adaptation, survival, and competence in the face of increasingly discontinuous environmental change.... Essentially, it embodies organisational processes that seek synergistic combination of data and information processing capacity of information technologies, and the creative and innovative capacity of human beings.” This definition not only gives an indication of what Knowledge Management is, but of how its advocates often treat the English language. In simpler terms, Knowledge Management seeks to make the best use of the knowledge that is available to an organisation, creating new knowledge in the process. It is helpful to make a clear distinction between knowledge on the one hand, and information and data on the other. Information can be considered as a message. It typically has a sender and a receiver. Information is the sort of stuff that can, at least potentially, be saved onto a computer. Data is a type of information that is structured, but has not been interpreted. Knowledge might be described as information that has a use or purpose. Whereas information can be placed onto a computer, knowledge exists in the heads of people. Knowledge is information to which intent has been attached.

3.2.1 First and Second Generation Knowledge Management By the early nineties, it was clear that there were two distinct branches of Knowledge Management. First Generation Knowledge Management involves the capture of information and experience so that it is easily accessible in a corporate environment. An alternate term is “knowledge capture”. Managing this capture allows the system to grow into a powerful information asset. This first branch had its roots firmly in the use of technology. In this view Knowledge Management is an issue of information storage and retrieval. It uses ideas derived 77

Information Systems

from systems analysis and management theory. This approach led to a boom in consultancies and in the development of so-called knowledge technologies. Typically first-generation Knowledge Management involved developing sophisticated data analysis and retrieval systems with little thought as to how the information they contained would be developed or used. This led to organisations investing heavily in technological fixes that had either little impact or a negative impact on the way in which knowledge was used. A typical scenario might have seen an organisation install a sophisticated intranet in order to categorise and disseminate information, only to find that the extra work involved in setting up the metadata meant that few within the organisation actually used the intranet. This occasionally led to management mandating the use of the intranet, resulting in resentment amongst staff, and undermining their trust in the organisation. Thus first generation solutions are often counterproductive. Management theory functions as a branch of Economics, and to a large extent it adopts econometric standards. When it became apparent that it would be useful to be able to manage knowledge, it was natural for managers to attempt to apply their preferred econometric methods to the cause. But econometrics is about commodities and cash flow. It found it therefore necessary to treat knowledge as if it were a commodity. This, of course, was a surprisingly difficult thing to do, essentially because knowledge is not a commodity but a process. But a suitable epistemology was found, in the form of that developed by Michael Polanyi. Polanyi’s epistemology objectified the cognitive component of knowledge – learning and doing – by labelling it tacit knowledge and for the most part removing it from the public view. Learning and doing became a ‘black box’ that was not really subject to management; the best that could be done was to make tacit knowledge explicit. Its failure to provide any theoretical understanding of how organisations learn new things and how they act on this information meant that first generation Knowledge Management was incapable of managing knowledge creation. Second Generation Knowledge Management: Faced with the theoretical and practical failure of first generation techniques to live up to its promise, theorists began to look more closely at the ways in which knowledge is created and shared. Along with this realisation came a change in metaphor. Organisations came to be seen as capable of learning, and so a link grew between learning theory and management. At the same time hierarchical models of organisational structure were replaced by more organic models, which see effective organisations as capable of structural change in response to their environment. The advent of complexity theory and chaos theory provided more metaphors that enable managers to replace models of organisations as integrated systems with models of organisations as complex interdependent entities that are capable of responding to their environment. Second generation Knowledge Management gives priority to the way in which people construct and use knowledge. It derives its ideas from complex systems, often making use of organic metaphors to describe knowledge growth. It is closely related to organisational learning. It recognises that learning and doing are more important to organisational success than dissemination and imitation.

3.2.2 Knowledge Knowledge is the awareness and understanding of facts, truths or information gained in the form of experience or learning. Knowledge is an appreciation of the possession of interconnected details which, in isolation, are of lesser value.

Intelligence Information Systems

Knowledge is a term with many meanings depending on context, but is (as a rule) closely related to such concepts as meaning, information, instruction, communication, representation, learning and mental stimulus. Knowledge is distinct from simple information. Both knowledge and information consist of true statements, but knowledge is information that has a purpose or use. Philosophers would describe this as information associated with intentionality. The study of knowledge is called epistemology. A common definition of knowledge is that it consists of justified true belief. This definition derives from Plato’s Theaetetus. It is considered as necessary, but not sufficient, conditions for some statement to count as knowledge. What constitutes knowledge certainty and truth are controversial issues. These issues are debated by philosophers, social scientists, and historians. Ludwig Wittgenstein wrote “On Certainty” — aphorisms on these concepts — exploring relationships between knowledge and certainty. A thread of his concern has become an entire field, the philosophy of action. Distinguishing knowing that from knowing how Suppose that Fred says to you: “The fastest swimming stroke is the front crawl. One performs the front crawl by oscillating the legs at the hip, and moving the arms in an approximately circular motion”. Here, Fred has propositional knowledge of swimming and how to perform the front crawl. However, if Fred acquired this propositional knowledge from an encyclopedia, he will not have acquired the skill of swimming: he has some propositional knowledge, but does not have any procedural knowledge or “know-how”. In general, one can demonstrate know-how by performing the task in question, but it is harder to demonstrate propositional knowledge. Inferential vs. Factual Knowledge Knowledge may be factual or inferential. Factual knowledge is based on direct observation. It is still not free of uncertainty, as errors of observation or interpretation may occur, and any sense can be deceived by illusions. Inferential knowledge is based on reasoning from facts or from other inferential knowledge such as a theory. Such knowledge may or may not be verifiable by observation or testing. For example, all knowledge of the atom is inferential knowledge. The distinction between factual knowledge and inferential knowledge has been explored by the discipline of general semantics.

3.2.3 Approach for Successful Implementation of Knowledge Management Although KM is as an enterprise-wide goal, many companies find success if they kickoff an initiative in one department and then extend the practices throughout other parts of the organisation. Here, we will outline those practices that help ensure a successful KM initiative within the IT help desk or customer contact center. Often KM practices relating to service and support can be defined as knowledge-powered problem resolution — using a knowledge base, knowledge sharing, collaboration and knowledge reuse to efficiently solve customer questions. 79

Information Systems

A successful knowledge management initiative within a help desk or call center can reduce agent training time and speed new employee ramp up. Knowledge-powered problem resolution enables agents to become more confident and competent sooner than they otherwise would without a KM practice. By having access to a knowledge base, new help desk and customer service agents can get answers to common questions without having to constantly ask other more experienced agents. Customers and end-users benefit from faster problem resolution, and experienced agents can focus on solving more challenging problems. Customers and end-users also benefit when they have direct access to a knowledge base to solve their own issues without ever contacting an agent. A growing number of people now prefer self-service to live interaction, at least for certain problem types. For some people, self-service fits perfectly into their lifestyle. They are in a hurry and they need a specific piece of information and that’s all they want. Say, for example, in a corporate environment, an employee needs to know if there is a Windows 2000 driver for a USB Zip drive. She doesn’t want to wait in a queue. She doesn’t want to talk to an agent. She just wants to know if there is a driver available and where to find it. In this case, self-service can be superior to agent-assisted service. Knowledge Management is an evolving discipline that can be affected by new technologies and best practices, but there are some things that we do know for sure. There is a systematic approach to successfully implementing knowledge management and if you analyse what you are trying to accomplish, map out a strategy, garner support from the organisation and have a way to measure it, then you are much more likely to be successful., The outlined 11 points that will serve as a primer to help understand what it takes to have a successful Knowledge Management initiative. Point 1: Knowledge Management is a discipline A lot of people think knowledge management is a technology or software solution but it is much more than that; knowledge management is a discipline. Obviously, you have to have a good piece of software or a good system to capture knowledge – but that’s not the whole equation. Underestimating what it takes just to capture the knowledge correctly is a big risk, as is underestimating the integration task into your already complex environment. There are some providers of pre-packaged knowledge out there, but our experience is that while they can be useful to the help desk they are not relevant to customer service centers which have business-specific content needs. In either case, you must ensure you have the adequate resources to create and maintain the content you promise. Creating content is not a one-time project. Also, over time the content must be updated and supplemented as new products or services are supported as shown in Figure 1. Empowering agents to add new content as resolutions are discovered is the key to maintaining a robust system.

Intelligence Information Systems

Figure 1: Keeping KM updated

Point 2: One champion is not enough To be successful, your project must have several champions within the organisation. These are individuals that believe in the project, enthusiastically advocate it and have the clout to “make things happen.” Projects that lack a champion generally don’t get off the ground. Those with only one champion are also at serious risk. Losing your champion can spell disaster for your project. This is a real problem for knowledge management projects, due to their continuous duration. If the project champion transfers, retires or leaves the company, the project often loses its momentum and the project may falter as someone else takes it over. What we like to see when we work with clients is a dual-sponsorship: one at the operational level and one at the executive level. So if an operations manager decides the company really needs knowledge management, that manager should find somebody on the executive staff who will agree to support the vision. By having that dual track of vision the project is more likely to succeed. Point 3: Cultural change isn’t automatic Buy-in is needed at all levels, and this may require cultural change. The people that are going to use the tools have to be part of the design unless you plan on strongarming them (and that doesn’t work very well). Don’t make this management decision in a vacuum. Include some people from the various groups that would directly or indirectly use the system. Sometimes there is a fear that knowledge management will be used to replace people. If your staff thinks that is what you are trying to do, then you really need to address that head-on. If that is not your intention, you should convince your team that current head count reduction is not the goal. Therefore, you need to look for and plan the motivation for each party. After all, you are asking people to shift from a system where being a tower of knowledge is rewarded, to a system where they share their expertise with everybody on the team. Each party will have a unique motivation to embrace knowledge management. For example, in a technical support environment, a frontline tech will have a different motivational schema than a 3rd level technician. The frontline tech is not going to have to ask the 2nd line tech as many questions, and can resolve more problems faster. The 2nd level tech is not going to get as many of the common questions. Level 3 researchers won’t have to start at ground zero when handed a problem by level 2, because they know that all the intermediate steps have been covered. So as you look 81

Information Systems

across the organisation everybody has a different interest and you have to protect all of them. Failing to see how knowledge management is going to fit into the rest of the organisation is a mistake. You must invest the time and energy to understand the culture, identify motivations and ensure change happens where needed. Point 4: Create a change management plan If your employees are not already sharing information, you will need a change management plan because you are asking people to do their jobs differently. The change management plan specifies how you will gain acceptance of knowledge management within the organisation. Let’s say you are a call center manager and you measure your employees’ performance by call handle time and number of cases closed. Now you are going to be asking them to use a knowledge base on every call or email interaction – thus asking them to change the way they perform their job on a daily basis. Also, if you don’t make changes to their performance reviews and compensation, there may be friction because you’re asking them to do one thing but you are judging them by another set of rules. As part of the overall change management plan you need to update job descriptions, feedback sessions and performance reviews to reflect the new workflow. Neglecting to make these changes may foster acceptance issues with your team members. Point 5: Stay strategic Knowledge management is a strategic endeavour, not just a project. I prefer to call it a strategic initiative as opposed to a project because a project implies a finite timeline. With KM you are never really done; you initiate it and you build it and then it is online and you maintain it. In our practice we look for our clients to have a strategic goal for the project rather than a tactical goal. If you are looking to shorten handle time that’s a tactical motivation and you’re not as likely to be willing to go through the steps that a successful enterprise rollout would take. But if it is a strategic initiative, especially something that is top-down motivated (for instance improving customer service or improving employee satisfaction) then there is a better value statement involved and you are not relying on changing one metric. So you might see improvement in individual metrics like handle time and resolution rates but their value is limited compared to the return from becoming a collaborative knowledge sharing organisation. To get going, decide what goals you are trying to accomplish and why. Then try to identify a solution and methodology that will help you attain those goals in your environment. Sometimes people within an organisation may say that a KM initiative is nice-to-have, but an economic downturn might slow the process down or defer it — thus, being counterproductive when resources are scarce. But I think it’s counterproductive to consider KM a nice-to-have because the rewards are equally beneficial during both a downturn and the inevitable upturn. If you wait until the upturn then you will be forced to play catch up as your call volumes increase and your email volume doubles; that’s not the time to introduce a knowledge-powered system or build a knowledge base. It’s not necessary to hire more employees if you have resources that are not 100% utilized or if you encourage your agents to contribute knowledge during their daily workflow. Point 6: Pick a topic, go in-depth, and keep it current We advise that you pick one area that needs improvement or has limited resources, and then build a robust knowledge base for that subject matter. Use that experience to learn about implementing knowledge in your organisation; do one call center or one

product group and learn from there. It is much better to be comprehensive for a narrow topic than fail to get enough depth. Sometimes an enterprise initiative is needed right away, and it can be done successfully, but it can involve a larger resource commitment to do a full-scale project all at once. Remember, the depth of your knowledge base truly depends upon your customers’ needs.

Intelligence Information Systems

Today’s systems should enable agents to contribute new knowledge during their natural workflow. This is critical to ensure that solutions that are not currently in the system can be quickly added once the resolution has been determined. It’s also important to remember that regular and timely maintenance of the knowledge base is the key to success. You should also consider appointing resources to maintain the knowledge. Be sure to build in a mechanism that identifies gaps in content (information sought but not found), and a process for filling those gaps. If people repeatedly fail to find what they are looking for they will stop using the system. Point 7: Don’t get hung up on the limitations Certain types of knowledge are very well suited to quickly harvesting into a knowledge base. Company processes or technical procedures are well suited for knowledge management. By populating a knowledge base with this type of information and making it available to employees and customers, an organisation can shorten or even avoid many calls. Organisations can also use a KM system to access existing unstructured sources of information that may already exist on a corporate network, intranet or within an existing call center or help desk system. It’s important to note that experienced agents can certainly benefit from access to both structured knowledge and unstructured information because they’re more likely to be able to pinpoint a solution within an unstructured document. However, level 1 agents or end-users accessing the knowledge base through self-service, may not find these sources of unstructured information helpful because they don’t have the expertise to decipher the information quickly. In addition to sources of knowledge, the specific type of information is also important to consider. The craftsmanship or expertise that a true expert has is much more difficult to capture. A master craftsman has a huge body of knowledge. S/he tends to “chunk” their knowledge and can’t tell you the steps they use when they make a decision in their field; they just do it. Much like tying your shoe, you do it everyday but when you have to explain it its tough because you have internalized the process. I think that is where the breakdown is for harvesting expertise. We think a KM initiative could be somewhat limited because of the nature of complex knowledge, and thankfully we will always need human expertise. However, when it comes to a successful initiative, it’s important to first determine what knowledge can be easily added to the system and then provide agents or a knowledge manager with the tools to add this step-by-step complex information to the system, ensuring that even difficult questions can be answered accurately. Point 8: Set expectations or risk extinction A big pitfall is the failure of knowledge management proponents in helping executive management set appropriate expectations. Customers, employees and management alike must know what they are going to get out of knowledge management, what it will take to get those results and how success will be measured. Measurement is where most organisations fail because they are doing things that were not measured before. So a year from now, you’ve built this thing, it’s up and running and everyone loves it and your boss says “where’s my return?” If you don’t have a measurement system in place then you will have a hard time answering his or her question – especially for the new metrics that didn’t exist before. You probably measured handle time, abandon rates, and similar operational metrics. But you may not be measuring call avoidance or knowledge usage, which affects ultimately the ability to measure resolution rates. 83

Information Systems

In addition to setting management expectations you have to set customer and end-user expectations. For example, if you are going to provide customers with Web selfservice for one specific product then you must include the known problems that they are going to encounter in the knowledge base. In that situation you are better off to set their expectations that the knowledge base covers only that product and no other. Customers pose the same extinction risk that your employees do. If they visit the site a few times and they can’t find an accurate or appropriate answer they will probably not return again. Point 9: Integrate KM into existing systems Typically, organisations that are implementing knowledge management already have an established data center, so they are not only building a knowledge base – they must also integrate it into their existing environment – their call tracking system, IVR system, email, remote diagnostics and other support systems. When selecting a KM system, consider systems that have open architectures and proven integrations into existing call center and help desk tools to ensure a successful implementation. Also, processes will be affected, requiring change to reporting and measurement systems as well. Integrate reporting capabilities where possible to best understand how the combined systems are affecting the effectiveness of your support operations. Point 10: Educate your self-service users You’ve created your KM plan, determined the critical knowledge to include, initiated a plan to garner cultural acceptance, trained your agents and pinpointed key sources of knowledge – finally you need to educate your self-service users on how to find and access support information online to ensure a satisfying experience. There are many ways to “push” your self-service capabilities out to your end-user audience. Traditional marketing techniques should be employed to promote this valuable service, such as email, online newsletters or direct mail. Encourage users to visit your online support site by making it easy to find and access the knowledge base. Be sure to include the site URL and directions for obtaining a login, if needed, in your marketing communications. Another method is to encourage your agents to end support calls by informing the user of the support site. “Thanks for calling today, I’m glad that I could help you solve your problem. By the way, we now have a Web self-service site if you’d like to search the knowledge base. You can find it at www.ABC-Support.com and you can obtain a login by clicking the request login button on that page.” Finally, make sure your Internet or intranet site includes an easy-to-find link to your Web self-service site. A twist on the old saying, “If they can’t find it, they won’t come.” So make it easy to find, easy to access and easy to use. Point 11: Become a knowledge-enabled organisation We think it is inevitable that knowledge management will have a high adoption rate in the next few years. Over time to remain competitive it will be essential to be “knowledge-enabled.” Just a few years ago email was not a common method for seeking customer service; now customers demand the ability to contact you through channels other than the phone. Going forward, as customers deal with companies that are knowledge-enabled and can quickly and efficiently answer their questions, they are going to expect a greater level of service in all of their support interactions. The bottom line can be summarized with a quote from Gartner, Inc. – “Those enterprises that include KM processes as part of their customer relationship management initiatives have a higher probability of success than those that don’t”.

3.3 CREATING, DEVELOPING AND SHARING KNOWLEDGE

Intelligence Information Systems

Knowledge flows comprise the set of processes, events and activities through which data, information, knowledge and meta-knowledge are transformed from one state to another. To simplify the analysis of knowledge flows, the framework described here is based primarily on the Knowledge Model. The model organizes knowledge flows into four primary activity areas: knowledge creation, retention, transfer and utilisation (Figure 2).

Creation

Utilization

Retention

Transfer Figure 2: Knowledge model

Knowledge Creation: This comprises activities associated with the entry of new knowledge into the system, and includes knowledge development, discovery and capture. Knowledge Retention: This includes all activities that preserve knowledge and allow it to remain in the system once introduced. It also includes those activities that maintain the viability of knowledge within the system. Knowledge Transfer: This refers to activities associated with the flow of knowledge from one party to another. This includes communication, translation, conversion, filtering and rendering. Knowledge Utilisation: This includes the activities and events connected with the application of knowledge to business processes. Let us, look at the basic processes of knowledge creation and sharing within organisations and what type of technologies can be applied to knowledge management and to assess their actual or potential contribution.

3.3.1 Knowledge Creation and Sharing A set of systematic and disciplined actions that an organisation can take to obtain the greatest value from the knowledge available is given the name Knowledge management. â&#x20AC;&#x153;Knowledgeâ&#x20AC;? in this context includes both the experience and understanding of the people in the organisation and the information artifacts, such as documents and reports, available within the organisation and in the world outside. Effective knowledge management typically requires an appropriate combination of organisational, social, and managerial initiatives along with, in many cases, deployment of appropriate technology.

Information Systems

To structure the discussion of processes involved in knowledge creation and sharing and technologies involved, it is helpful to classify the technologies by reference to the notions of tacit and explicit knowledge. •

Tacit knowledge is what the knower knows, which is derived from experience and embodies beliefs and values. Tacit knowledge is actionable knowledge, and therefore the most valuable. Furthermore, tacit knowledge is the most important basis for the generation of new knowledge; however, the key to knowledge creation is the mobilisation and conversion of tacit knowledge.

•

Explicit knowledge is represented by some artifact, such as a document or a video, which has typically been created with the goal of communicating with another person. Both forms of knowledge are important for organisational effectiveness. Now, let us look at processes by which knowledge is transformed between its tacit and explicit forms, as shown in Figure 3. Organisational learning takes place as individuals participate in these processes, since by doing so their knowledge is shared, articulated, and made available to others. Creation of new knowledge takes place through the processes of combination and internalisation. As shown in Figure 3, the processes by which knowledge is transformed within and between forms usable by people are: •

Socialisation (tacit to tacit): Socialisation includes the shared formation and communication of tacit knowledge between people, e.g., in meetings. Knowledge sharing is often done without ever producing explicit knowledge and, to be most effective, should take place between people who have a common culture and can work together effectively. Thus, tacit knowledge sharing is connected to ideas of communities and collaboration. A typical activity in which tacit knowledge sharing can take place is a team meeting during which experiences are described and discussed, often informal, in which information technology (IT) plays a minimal role. However, an increasing proportion of meetings and other interpersonal interactions use online tools known as groupware. These tools are used either to supplement conventional meetings, or in some cases to replace them. To what extent can these tools facilitate formulation and transfer of tacit knowledge?

Groupware: Groupware is a fairly broad category of application software that helps individuals to work together in groups or teams. Groupware can to some extent support all four of the facets of knowledge transformation. To examine the role of groupware in socialization we focus on two important aspects: shared experiences and trust.

Intelligence Information Systems

Shared experiences are an important basis for the formation and sharing of tacit knowledge. Groupware provides a synthetic environment, often called a virtual space, within which participants can share certain kinds of experience; for example, they can conduct meetings, listen to presentations, have discussions, and share documents relevant to some task. Indeed, if a geographically dispersed team never meets face to face, the importance of shared experiences in virtual spaces is proportionally enhanced. An example of current groupware is Lotus Notes, which facilitates the sharing of documents and discussions and allows various applications for sharing information and conducting asynchronous discussions to be built. Groupware might be thought to mainly facilitate the combination process, i.e., sharing of explicit knowledge. However, the selection and discussion of explicit knowledge to some degree constitutes a shared experience. A richer kind of shared experience can be provided by applications that support real-time on-line meetings, a more recent category of groupware. On-line meetings can include video and text-based conferencing, as well as synchronous communication and chat. Text-based chat is believed to be capable of supporting a group of people in knowledge sharing in a conversational mode. Commercial products of this type include Lotus Sametime and Microsoft NetMeeting. These products integrate both instant messaging and on-line meeting capabilities. Instant messaging is found to have properties between those of the personal meeting and the telephone: it is less intrusive than interrupting a person with a question but more effective than the telephone in broadcasting a query to a group and leaving it to be answered later. Some of the limitations of groupware for tacit knowledge formation and sharing have been highlighted by recent work on the closely related issue of the degree of trust established among the participants. It was found that videoconferencing (at high resolution窶馬ot Internet video) was almost as good as face-to-face meetings, whereas audio conferencing was less effective and text chat least so. These results suggest that a new generation of videoconferencing might be helpful in the socialization process, at least in so far as it facilitates the building of trust. But even current groupware products have features that are found to be helpful in this regard. In particular, access control, which is a feature of most commercial products, enables access to the discussions to be restricted to the team members if appropriate, which has been shown to encourage frankness and build trust. 窶｢

Externalisation (tacit to explicit): By its nature, tacit knowledge is difficult to convert into explicit knowledge. Through conceptualization, elicitation, and ultimately articulation, typically in collaboration with others, some proportion of a person's tacit knowledge may be captured in explicit form. Typical activities in which the conversion takes place are in dialog among team members, in responding to questions, or through the elicitation of stories. The conversion of tacit to explicit knowledge (externalization) involves forming a shared mental model, then articulating through dialog. Collaboration systems and other groupware (for example, specialized brainstorming applications) can support this kind of interaction to some extent. 87

Information Systems

On-line discussion databases are another potential tool to capture tacit knowledge and to apply it to immediate problems. It needs to be noted that team members may share knowledge in groupware applications. To be most effective for externalization, the discussion should be such as to allow the formulation and sharing of metaphors and analogies, which probably requires a fairly informal and even freewheeling style. This style is more likely to be found in chat and other real-time interactions within teams. Newsgroups and similar forums are open to all, unlike typical team discussions, and share some of the same characteristics in that questions can be posed and answered, but differ in that the participants are typically strangers. Nevertheless, it is found that many people who participate in newsgroups are willing to offer advice and assistance, presumably driven by a mixture of motivations including altruism, a wish to be seen as an expert, and the gratitude and positive feedback contributed by the people they have helped.

3.3.2 Capturing Knowledge Once tacit knowledge has been conceptualized and articulated, thus converting it to explicit knowledge, capturing it in a persistent form as a report, an e-mail, a presentation, or a Web page makes it available to the rest of the organisation. Technology already contributes to knowledge capture through the ubiquitous use of word processing, which generates electronic documents that are easy to share via the Web, e-mail, or a document management system. Capturing explicit knowledge in this way makes it available to a wider audience, and “improving knowledge capture” is a goal of many knowledge management projects. • Combination: (explicit to explicit): Explicit knowledge can be shared in meetings, via documents, e-mails, etc., or through education and training. The use of technology to manage and search collections of explicit knowledge is well established. However, there is a further opportunity to foster knowledge creation, namely to enrich the collected information in some way, such as by reconfiguring it, so that it is more usable. An example is to use text classification to assign documents automatically to a subject schema. A typical activity here might be to put a document into a shared database.There can be little doubt that the phase of knowledge transformation best supported by IT is combination, because it deals with explicit knowledge. We can distinguish the challenges of knowledge management from those of information management by bearing in mind that in knowledge management the conversion of explicit knowledge from and to tacit knowledge is always involved. • Internalisation (explicit to tacit): In order to act on information, individuals have to understand and internalize it, which involves creating their own tacit knowledge. By reading documents, they can to some extent re-experience what others previously learned. By reading documents from many sources, they have the opportunity to create new knowledge by combining their existing tacit knowledge with the knowledge of others. However, this process is becoming more challenging because individuals have to deal with ever-larger amounts of information. A typical activity would be to read and study documents from a number of different databases. These processes do not occur in isolation, but work together in different combinations in typical business situations. For example, knowledge creation results from interaction of persons and tacit and explicit knowledge. Through interaction with others, tacit knowledge is externalized and shared. Although individuals, such as employees, for example, experience each of these processes from a knowledge management and therefore an organisational perspective, the greatest value occurs from their combination since, as already noted, new knowledge is thereby created, disseminated, and internalized by other employees who can therefore act on it and thus 88

form new experiences and tacit knowledge that can in turn be shared with others and so on. Since all the processes of Figure 3 are important, it seems likely that knowledge management solutions should support all of them, although we must recognise that the balance between them in a particular organisation will depend on the knowledge management strategy used.

Intelligence Information Systems

Table 1 shows some examples of technologies that may be applied to facilitate the knowledge conversion processes of Figure 3. The individual technologies are not in themselves knowledge management solutions. Instead, when brought to market they are typically embedded in a smaller number of solutions packages, each of which is designed to be adaptable to solve a range of business problems. Examples are portals, collaboration software, and distance learning software. Each of these can and does include several different technologies. Table 1: Examples of technologies that can support or enhance the transformation of knowledge

Tacit to Explicit Answering questions Annotation Explicit to Explicit Text search Document categorization

It is found that the strongest contribution to current solutions is made by technologies that deal largely with explicit knowledge, such as search and classification. Contributions to the formation and communication of tacit knowledge, and support for making it explicit, are currently weaker, although some encouraging developments are highlighted, such as the use of text-based chat, expertise location, and unrestricted bulletin boards. Knowledge capture stages Knowledge may be accessed, or captured, at three stages: before, during, or after knowledge-related activities. For example, individuals undertaking a new project for an organisation might access KM resources to learn best practices and lessons learnt for similar projects undertaken previously, access the KM network again during the project implementation to seek advice on issues encountered, and access the system afterwards for advice on after-project actions and review activities. Similarly, knowledge may be captured and recorded into the system before the project implementation, for example, as the project team learns information and lessons during the initial project analysis. Similarly, lessons learnt during the project operation may be entered into the KM system, and after-action reviews may lead to further insights and lessons being recorded in the KM system for future access.

3.3.3 Knowledge Transfer and Organisation In the Organisational development area of organisational learning, a practical problem is that of knowledge transfer, how to get some packet of knowledge, that exists in one part of the organisation, into another (or all other) parts of the organisation. Itâ&#x20AC;&#x2122;s more than just a communications problem. If it were merely that, then a memo, an e-mail or a meeting would accomplish the knowledge transfer. Challenges What complicates knowledge transfer? There are many factors, including: â&#x20AC;˘ â&#x20AC;˘

3.3.4 Drivers of Knowledge Management There are a number of ‘drivers’, or motivations, leading to organisations undertaking a Knowledge Management program. Perhaps first among these are to gain the competitive advantage that comes with improved or faster learning and new knowledge creation. KM programs may lead to greater innovation, better customer experiences, consistency in best practices and knowledge access across a global organisation, as well as many other benefits, and KM programs may be driven with these goals in mind. Considerations driving a knowledge management program might include: • • • • •

•

• •

making available increased knowledge content in the development and provision of products and services. achieving shorter new product development cycles. facilitating and managing organisational innovation. leverage the expertise of people across the organization. Benefiting from ‘network effects’ as the number of productive connections between employees in the organisation increases and the quality of information shared increases. managing the proliferation of data and information in complex business environments and allowing employees to rapidly access useful and relevant knowledge resources and best practice guidelines. facilitate organisational learning. managing intellectual capital and intellectual assets in the workforce (such as the expertise and know-how possessed by key individuals) as individuals retire − in larger numbers than they have in a long time - and new workers are hired.

Knowledge Management enablers Historically, there have been a number of technologies ‘enabling, or facilitating KM practices in the organisation, including expert systems, knowledge bases, software help desk tools, document management systems and other IT systems supporting organisational knowledge flows. The advent of the internet brought with it further enabling technologies, including Elearning, web conferencing, collaborative software, Content management systems, corporate ‘Yellow pages’ directories, email lists, Wikis, Blogs, and other technologies. Each enabling technology can expand the level of inquiry available to an employee, while providing a platform to achieve specific goals or actions. The practice of KM will continue to evolve with the growth of collaboration applications available by IT and through the Internet. Since its adoption by the mainstream population and business 90

community, the Internet has led to an increase in creative collaboration, learning and research, e-commerce, and instant information.

Intelligence Information Systems

There are also a variety of organisational enablers for KM programs, including Communities of Practice, before-, after- and during- action reviews, peer assists, information taxonomies, coaching and mentoring, and so on.

3.3.5 Knowledge Representation Knowledge representation is a central problem in arranging knowledge. It is needed for library classification and processing concepts in an information system. There are difficulties in the field of artificial intelligence. The problem consists of how to store and manipulate knowledge in an information system in a formal way so that it may be used by mechanisms to accomplish a given task. Examples of applications are expert systems, machine translation systems, computer-aided maintenance systems and information retrieval systems (including database front-ends). Some people think it would be best to represent knowledge in the same way that it is represented in the human mind, which is the only known working intelligence so far, or to represent knowledge in the form of human language. Unfortunately, we don’t know how knowledge is represented in the human mind, or how to manipulate human languages in the same way as the human mind. For this reason, various artificial languages and notations have been proposed for representing knowledge. They are typically based on logic and mathematics, and have easily parsed grammars to ease machine processing. The recent fashion in knowledge representation languages is to use XML as the lowlevel syntax. This tends to make the output of these KR languages easy for machines to parse, at the expense of human readability. First-order predicate calculus is commonly used as a mathematical basis for these systems, to avoid excessive complexity. However, even simple systems based on this simple logic can be used to represent data which is well beyond the processing capability of current computer systems: Examples of notations: • •

DATR is an example for representing lexical knowledge RDF is a simple notation for representing relationships between objects

Examples of artificial languages intended for knowledge representation include: • • • •

CycL Loom OWL KM

Techniques of knowledge representation Semantic networks may be used to represent knowledge. Each node represents a concept and the arcs are used to define relations between the concepts. From the earliest times, the knowledge frame or just frame has been used. A frame consists of slots which contain values; for instance, the frame for house might contain a color slot, number of floors slot, etc.

Information Systems

Frames can behave something like object-oriented programming languages, with inheritance of features described by the “is-a” link. However, there has been no small amount of inconsistency in the usage of the “is-a” link: Ronald J. Brachman wrote a paper titled “What IS-A is and isn’t”, wherein 29 different semantics were found in projects whose knowledge representation schemes involved an “is-a” link. Other links include the “has-part” link. Frame structures are well-suited for the representation of schematic knowledge and stereotypical cognitive patterns. The elements of such schematic patterns are weighted unequally, attributing higher weights to the more typical elements of a schema. A pattern is activated by certain expectations: If a person sees a big bird, he or she will classify it rather as a sea eagle than a golden eagle, given his or her “sea-scheme” is currently activated. Frames representations are more object-centers than semantic networks: all the facts and properties of a concept are located in one place - there is no need for costly search processes in the database. Frames suffer from the frame problem of knowledge linking. A script is a type of frame that describes what happens temporally; the usual example given is that of describing going to a restaurant. The steps include waiting to be seated, receiving a menu, ordering, etc.

3.4 ARTIFICIAL INTELLIGENCE IN BUSINESS Intelligence is the capability to solve perceptual problems. By the term “perceptual”, we mean individual, special, random, fuzzy, sensory, and/or emotional. Solving such 92

problems requires accumulation, induction and inference of experiences to form new knowledge.

Intelligence Information Systems

Artificial intelligence (abbreviated AI) is defined as intelligence exhibited by an artificial entity. Such an entity is generally computer-controlled; therefore artificial intelligence in this context is pre-programmed. Humans use intuition and viewpoints to make judgments and choices instead of using precise rules or procedures. However, almost none of those used by human beings can be done programmatically. In conclusion, we can say that no matter how powerful a computer might be, if it works only upon a given set of rules/programs, it is not regarded as having real intelligence. Research in AI is concerned with producing machines to automate tasks requiring intelligent behavior. Examples include control, planning and scheduling, the ability to answer diagnostic and consumer questions, handwriting, speech, and facial recognition. As such, it has become a scientific discipline, focused on providing solutions to real life problems. AI systems are now in routine use in economics, medicine, engineering and the military, as well as being built into many common home computer software applications, traditional strategy games like computer chess and other video games. Schools of thought AI is divided roughly into two schools of thought: Conventional AI and Computational Intelligence (CI). Conventional AI mostly involves methods now classified as machine learning, characterized by formalism and statistical analysis. This is also known as symbolic AI, logical AI, neat AI and Good Old Fashioned Artificial Intelligence (GOFAI). AI Methods include • • • •

Expert systems: apply reasoning capabilities to reach a conclusion. An expert system can process large amounts of known information and provide conclusions based on them. Case based reasoning. Bayesian networks. Behaviour based AI: a modular method of building AI systems by hand.

Computational Intelligence involves iterative development or learning (e.g. parameter tuning e.g., in connectionist systems). Learning is based on empirical data and is associated with non-symbolic AI, scruffy AI and soft computing. Methods mainly include: Neural networks: systems with very strong pattern recognition capabilities. •

Fuzzy systems: techniques for reasoning under uncertainty, has been widely used in modern industrial and consumer product control systems.

•

Evolutionary computation: applies biologically inspired concepts such as populations, mutation and survival of the fittest to generate increasingly better solutions to the problem. These methods most notably divide into evolutionary algorithms (e.g., genetic algorithms) and swarm intelligence (e.g., ant algorithms).

With hybrid intelligent systems attempts are made to combine these two groups. Expert inference rules can be generated through neural network or production rules from statistical learning such as in ACT-R.

Information Systems

A promising new approach called intelligence amplification tries to achieve artificial intelligence in an evolutionary development process as a side-effect of amplifying human intelligence through technology. History of commercial AI applications It was not until the late 1970s that the first commercial AI based System, XCON (Expert System), was developed. At that time, practical, commercial applications of AI were still rare. In the early 1980s, Fuzzy Logic techniques were implemented on Japanese subway trains and in a production application by a Danish cement manufacturer. Commercial AI products were only returning a few million dollars in revenue at this time. The Expert Systems that companies are starting to use, and the AI groups in many large companies, were formed in the mid-1980s. Expert Systems started to show limits on the amount of rules they can work with, and 1986 sales of AI-based hardware and software were $425 million (WFMO, 2001). Likewise, interest in using Neural Nets in business applications developed. By the end of the 1980s, Expert Systems were increasingly used in industry, and other AI techniques were being implemented, often unnoticed but with beneficial effect (WFMO, 2001). AI revenues reach $1 billion (MIT, Timeline of AI, 2001). In the early 1990s, AI applications such as automatic scheduling software, software to manage information for individuals, automatic mortgage underwriting systems, and automatic investment decision makers were used. In the mid-1990s, AI software to improve the prediction of daily revenues and staffing requirements for a business, credit fraud detection systems, and support systems were developed and used. It was not until the late-1990s that the applications such as data mining tools, e-mail filters, and web crawlers were developed and generally accepted. Artificial intelligence methods for business use We will discuss AI methods used in business namely Expert System, Artificial Neural Network (ANN), and Evolutionary Algorithm (EA) and move on to Hybrid Systems, (the AI methods that are used to complement, or in combination with these); Fuzzy Logic and Data Mining. Expert System: One of the accepted definition of Expert System is “A computer program with the expertise embodied in it, based on interview by a knowledge worker of the expert in that domain”. During the “knowledge acquisition” it will not only be the "knowledge" of experts that will be cloned and built into these systems, but also their intuition and the way that they reason, so that the best options can be selected under any given set of circumstances. An Expert System can be developed by: Expert System Shell software that has been specifically designed to enable quick development, AI languages, such as LISP and Prolog or through the conventional languages, such as Fortran, C++, Java, etc. While the Expert System concept may sound futuristic, one of the first commercial Expert Systems, called Mycin, was already in business use in 1974. Mycin, which was created by Edward H. Shortliffe at Stanford University, is one of the most famous Expert Systems. Mycin was designed as a medical diagnosis tool giving information concerning a patient's symptoms and test results; Mycin attempted to identify the cause of the patient's infection and suggested treatments. It was observed by some users that Mycin produced better analysis than medical students or practising doctors, provided its limitations were observed. Another example of an Expert System is Dendral, a computerized chemist. According to the Massachusetts Institute of Technology, the success of Dendral helped to convince computer science researchers

that systems using heuristics were capable of mimicking the way human experts solve problems.

Intelligence Information Systems

As regards to Potential Applications for an Expert System, these have been developed for a variety of reasons, including: the archiving of rare skills, preserving the knowledge of retiring personnel, and to aggregate all of the available knowledge in a specific domain from several experts, (when no single expert has complete knowledge of that domain). Perhaps an expert’s knowledge is needed more frequently than the expert can handle, or in places that the expert cannot travel to. The Expert System can train new employees or eliminate large amounts of the monotonous work humans do, thereby saving the expert 'time for situations requiring his or her expertise. In our opinion the only limit on the possible applications of stored knowledge in an Expert System is what the mind can imagine. We may Conclude that the Expert System is an AI application that takes decisions based on knowledge and inference (the ability to react on the knowledge), as defined by experts in a certain domain and to solve problems in that domain. The Expert System normally falls under the definition of Weak AI, and is one of the AI techniques that has been easiest for companies to embrace. Commercial Expert Systems were developed during the 1970s, and continue to be used by companies. One advantage of an Expert System is that it can explain the logic behind a particular decision, why particular questions were asked, and/or why an alternative was eliminated. That is not the case with other AI methods. Artificial Neural Network: Sometimes the following distinction is made between the terms “Neural Network” and “Artificial Neural Network”. “Neural network” indicates networks that are hardware based and “Artificial Neural Network” normally refers to those which are software-based. In the following paragraphs, “Artificial Neural Network” is sometimes referred to as “Neural Network” or “Neural Computing”. Neural Networks are an approach, which is inspired by the architecture of the human brain. In the human brain a neural network exists, which is comprised of over 10 billion neurons; each neuron then builds hundreds and even thousands of connections with other neurons. “Neural computing is defined as the study of networks of adaptable nodes which, through a process of learning from task examples, store experimental knowledge and make it available for use.”. As a Neural Network (NN) is designed, rather than being programmed, the systems learn to recognize patterns. Learning is achieved through repeated minor modifications to selected neuron weights (The weight is equal to the importance of the neuron). NN typically starts out with randomized weights for all their neurons. This means that they do not “know” anything, and must be trained. Once a NN has been trained correctly, it should be able to find the desired output to a given input; however, it cannot be guaranteed that a NN will produce the correct output pattern. NN learns by either a supervised or an unsupervised learning process. i)

The Supervised Learning Process: A supervised learning process has a target pattern (desired output). While learning different input patterns, the weight values are changed dynamically until their values are balanced, so that each input will lead to the desired output. There are two supervised learning algorithms: Forward, and Back-propagation, Learning Algorithms.

ii)

An unsupervised Neural Network has no target outputs. During the learning process, the neural cells organise themselves in groups, according to input pattern. The incoming data is not only received by a single neural cell, but also influences other cells in its neighbourhood. The goal is to group neural cells with similar functions close together. Self-organisation Learning Algorithms tend to discover patterns and relationships in that data. 95

Artificial Neural Network Techniques: There are many kinds of Artificial Neural Networks. No one knows exactly how many. This dissertation only examines the most common ones. (i) Perceptron, (ii) Multi-Layer-Perceptron, (iii) Backpropagation Net, (iv) Hopfield Net Physicist, and (v) Kohonen Feature Map. ANN as a method of Forecasting: “Forecasting is essential to business. NN does this job better than traditional forecasting methods. The advantages of ANN over traditional statistical forecasting methods are that ANN do not have to fulfill any statistical assumptions and the ability to handle non-linearity, which are common in business. Further advantages are that ANN is easy to learn and use, and normally requires less data preparation. We can conclude that ANN is inspired by the architecture of the human brain, and learns to recognise patterns through repeated minor modifications to selected neuron weights. There are many kinds of ANN techniques that are good at solving problems involving patterns, pattern mapping, pattern completion, and pattern classification. ANN pattern recognition capability makes it useful to forecast time series in business. A Neural Network can easily recognise patterns that have too many variables for humans to see. They have several advantages over conventional statistical models: they handle noisy data better, do not have to fulfil any statistical assumptions, and are generally better at handling large amounts of data with many variables. A problem with Neural Networks is that it is very difficult to understand their internal reasoning process, however, this is not entirely accurate. It is possible to get an idea about the learned ANN variables’ elasticity. By changing one variable at a time, looking at the changes in the output pattern during that time, at least some information regarding the importance of the different variables will be visible. Neural Networks can be very flexible systems for problem solving. Evolutionary Algorithm is “an algorithm that maintains a population of structures (usually randomly generated initially) that evolves according to rules of selection, recombination, mutation and survival referred to as genetic operators. A shared “environment” determines the fitness or performance of each individual in the population. It also tells us that the fittest individuals are more likely to be selected for reproduction (retention or duplication), while recombination and mutation modifies those individuals, yielding potentially superior ones. Branches of Evolutionary Algorithms: There are currently four main paradigms in (EA) research: Genetic Algorithm (GA), with two sub-classes and Genetic Programming (GP), Evolutionary Programming, and Evolution Strategy.

•

Genetic Algorithm (GA), is inspired by Darwin’s theory about evolution. Solution to a problem solved by genetic algorithms is evolved. Algorithm is started with a set of solutions (represented by chromosomes) called population. Solutions from one population are taken and used to form a new population. This is motivated by a hope, that the new population will be better than the old one. Solutions are selected to form new solutions (offspring) according to their fitness — the more suitable they are the more chances they have to reproduce. This is repeated until some condition (for example, “number of populations or improvement of the best solution) is satisfied.”

•

Genetic programming (GP) is a programming technique that extends the Genetic Algorithm to the domain of whole computer programs. In GP, populations of programs are genetically bred to solve problems.

•

Evolutionary Programming and Evolution Strategy: Evolution programming uses mutations to evolve populations. Is a stochastic optimisation strategy similar to Genetic Algorithm, but instead places emphasis on the behavioural linkage between parents and their offspring, rather than seeking to emulate specific Genetic Operators as observed in nature. Evolutionary Programming is very similar to Evolution Strategies, although the two approaches developed independently.

Intelligence Information Systems

Advantage and Disadvantages: Examples of problems where EA have been quite successful are: Timetabling and Job-Shop Scheduling Problem (JSSP), finding the most beneficial locations for offices, etc., and typical Operational Research (OR) problems with many constraints. GA has proven to be well suited to optimisation of specific non-linear multivariable systems. GA is used in a variety of applications including scheduling, resource allocation, training ANNs, and selecting rules for fuzzy systems. “GAs should be used when there is no other known problem solving strategy, and the problem domain is NP-complete. That is where GAs comes into play, heuristically finding solutions where all else fails.” It is generally agreed that EAs are especially ill suited for problems where efficient ways of solving them are already known. We may conclude that the EA tries to mimic the process of biological evolution, complete with natural selection and survival of the fittest. The four main paradigms are Genetic Algorithm (GA), Genetic Programming (GP), Evolutionary Programming, and Evolution Strategy. EA is a useful method of optimisation when other techniques are not possible. EAs seem to offer an economic combination of simplicity and flexibility, and may be the better method for finding quick solutions than the more expensive and time consuming (but higher quality) OR methods. However, hybrid system between OR and EA should be able to perform quite well. It is expected that if a backward Evolutionary Algorithm is used on an accepted OR solution, maybe then the human eye could easily rearrange the first string in a more effective way. If EA then were to run the string through the normal forward process, the end result could be better than using EA on an unperfected start string. Hybrid System: More people have recently begun to consider combining the approaches into hybrid ones. Hybrid System is the system that uses more than one problem-solving technique in order to solve a problem”. There is a huge amount of interest in Hybrid Systems, for example: neural-fuzzy, neural-genetic, and fuzzygenetic hybrid systems. Researchers believe they can capture the best of the methods involved, and outperform the solitary methods. “Fuzzy Logic and Fuzzy Expert System” and “Data Mining” are deliberately placed under the heading of Hybrid System. Fuzzy Logic is a method that is combined with other AI techniques (Hybrid System) to represent knowledge and reality in a better way. Data Mining does not have to be a Hybrid System, but usually is, for example, IBM’s DB2 (Data Mining tool), which contains techniques (IBM, 2001) such as Statistics, ANN, GA, and Model quality graphics, etc. Let us now take a closer look at the methods. Fuzzy Logic and Fuzzy Expert Systems Fuzzy Logic resembles human reasoning, but uses estimated information and vagueness in a better way. The answers to realworld problems are rarely black or white, true or false, or start or stop. By using Fuzzy Logic, knowledge can be expressed in a more natural way (fuzzy logic instead of Boolean “Crisp” logic).

Information Systems

Fuzzy Logic is a departure from classical two-valued sets and logic, that uses "soft" linguistic (e.g,. large, hot, tall) system variables and a continuous range of truth values in the interval [0,1], rather than strict binary (True or False) decisions and assignments.” Fuzzy Logic is ideal for controlling non-linear systems and for modeling complex systems where an inexact model exists, or in systems where ambiguity or vagueness is common. There are many commercial products are available today which uses Fuzzy logic like washing machines, high speed train etc.

ii)

Fuzzy Expert Systems: Often Fuzzy Logic is combined with Expert Systems, such as the so-called Fuzzy Expert Systems which are the most common use of Fuzzy logic. These systems are also called “Fuzzy Systems” and use Fuzzy Logic instead of Boolean (crisp) logic. Fuzzy Expert Systems are used in several wide-ranging fields, including: Linear and Nonlinear Control Pattern Recognition, Financial Systems, Operation Research, Data Analysis, Pattern recognition etc.

We may conclude that a Hybrid system uses more than one technique, such as neuralfuzzy, neural-genetic, Fuzzy Expert System, Data Mining (most often), etc., to solve a problem. Fuzzy logic is incorporated into computer systems so that they represent reality better by using “non-crisp” knowledge. Often Fuzzy Logic is combined with Expert Systems, the so-called Fuzzy Expert System or more simply, “Fuzzy System.” Data Mining software most often uses various techniques, including Neural Networks, statistical and visualization techniques, etc. to turn what are often mountains of data into useful information. Data Mining does not always contain AI techniques. It is expected that it is quite possible that Data Mining will become a very useful tool for companies in the competition for market shares. More examples of commercial use of Artificial Intelligence:

Expert Systems For Equipment Failure Diagnosis: Many expert systems for diagnosis have been developed in maintenance management. An example of expert system for diagnosing ventilators is described below. Figure 4 shows the object (air fan) to be diagnosed and its possible areas and causes of failure.

Figure 6: Inference process

The acceleration and velocity of vibration at the sensing points 1, 2, 3, and 4 are measured. The causalities between these measured values and failures are obtained by using expert knowledge. This knowledge is expressed in a matrix and is transformed into production rules are in Figure 5. The precise diagnosis is carried out based on the spectral analysis of the vibration data. The levels of the fundamental and higher components of the data are calculated. The relationship between the level values and failures is obtained by using expert knowledge. This knowledge is represented by frames. By using this knowledge source, the process of inference process as shown in Figure 6.

Predictive Maintenance in Place of Preventive Maintenance With the help of AI the importance of predictive maintenance has increased although time based preventive maintenance has been used as a basic method. Predictive maintenance based on condition of the equipment that is for example, if we replace a bearing when the vibration exceeds a certain limit rather than being guided by replacing the bearing at a fixed interval. With use of predictive maintenance the extra time spent in breakdown maintenance can be avoided. Lastly, when the deterioration is slow, the predictive maintenance provides substantive time and cost advantages over the preventive maintenance performed at a set time interval. Thus, as demonstrated, the advantages of predictive maintenance include: • • • •

replacement period prolongation safety improvement accident prevention reliability improvement

Diagnostic techniques based on machine condition are used to detect degradation of any equipment. In Japan, these techniques have been known since the 1960s, particularly in the steel manufacturing industry. Here are some examples. Machinery and equipment • • • • •

Condition-based diagnosis techniques have also been used to identify the mode of failure in abnormal vibration, crack by nondestructive examination (ultrasonic or X-ray), corrosion, or degradation of insulation. A very popular technique is to detect the abnormal vibration in the bearing portions and the shaft of rotating machinery. The level of vibration in the machine axis is measured by using the acceleration pick-up at regular intervals, thus obtaining the tendency of increasing vibration. Many rotating machines are maintained by using this method. The precondition for a condition-based strategy is to make the deteriorating conditions more transparent and predictable. This is where Artificial Intelligence can be used to bring competitive advantages. Customer Relationship Management “Behaviour Analysis” Behaviour Analysis and prediction of possible behaviour by the customer and then accordingly planning the business activity can definitely boost the business and profitability for business activities like retail business at a departmental store, credit card issuance and collections of dues, insurance policies coverage and mortgage etc. Such analysis is successfully being carried out by using AI techniques. The benefit of these new systems is that they reduce the amount of time necessary to approve a loan by using the computer to take decisions based on the variables values. Without human influence in the decision-making process, it becomes a very clean decision without emotion or preconceived ideas. Whether to apply for or extend a loan is often a critical decision for a company or an individual. With this new fast approval are companies not making it too easy to make loans? Perhaps the time needed before AI came on the scene gave the borrower time to think it though carefully. However, the methods exist and are in use at this moment to make decisions. Evidently AI has penetrated the business of Credit Card Issuers, Collectors, Insurance and Mortgage. Customer Relationship Management “Support & Marketing” The Office Assistant in Microsoft’s Office packages uses AI and has a broad installed base today, with more than 90 percent of the Windows and Macintosh market, at the very least, this proves that support software containing AI has already penetrated the market. Advisory Expert Systems have been on the market for a long time. At HP the interactive advice system CAST/BW, provides quick, accurate hardware sizing, network configuration, and usage recommendations. The system turns expert knowledge from SAP, HP internal competency centres, the HP Enterprise Server Group, and existing SAP. The Expert System functions in the same way as working directly with HP. Business Warehouse implementations into an easy-to-use advisory tool, use of robots, and marketing agents, support the assumption that support system based on AI have already entered the business market and are frequently used. Company Control There are several AI-based programs that control what employees do on the Internet, and what they send and receive in their e-mail at work. It is also believed that while preventing access to inappropriate web sites could be acceptable, checking employees’ e-mail is going one step too far. Unless a reasonable limit is set, we will have a “Big 100

Brother” society. Furthermore, with all of the electronic information that companies receive today, it is expected that intelligent agents will be used more and more often to process information in automated and customized ways to ease information overload.

Intelligence Information Systems

Production Management AI software that learned to ‘breed’ factory schedules generates far better schedules than those that humans can produce with the help of Genetic Algorithms. With the case studies it has been proved that Data Mining with ANN, help solve some of the processing and interpretation problems for companies and have even played a key role in discovering oil fields. Finance Management Some believe that computers with Neural Networks are better at selecting stocks than people are. However, finding information regarding Neural Networks’ success in the field of finance is difficult, most likely because successful systems are being treated as company secrets. The discussion of AI in the financial context has generally indicated that AI techniques are somewhat useful to most financial applications. AI techniques should catch on in coming years given the growing complexity of the markets, which will require more computing power and analysis to deal with information overload. It seems that many systems are best used as assistants to an existing team of experts rather than on their own. We may conclude that AI has gained a foothold in the world of business. That foothold, moreover, is getting larger and larger as time goes by. One question which comes to mind is then why has it taken so long before these methods are visible in business applications. There appear to be four possible answers to that question. First, it seems that the development of processing power has been a catalyst that made it possible for AI-based system to gain a foothold in the business world. Furthermore, it is just lately that affordable computers with sufficient processing power have become available to companies. Second, AI often competes with business methods that have been quite successful and in use for very long periods of time. So, why risk changing a working concept, companies may think. There are also some interpretation difficulties in some AI systems for instance, old tried and true statistical methods win over ANN simply because people are unwilling to use a system where they do not see the effect of each variable (i.e., the Black Box). This can be a high threshold to overcome. Third, many AI applications involve large investments of money and failure can also be very costly; this makes the companies circumspect regarding investment decisions. Finally the fourth reason is simply that new technologies seems always to have a threshold for acceptance. Furthermore, many critics believe that AI has not fulfilled its promise. Yet they do not discard it as a method. It is a fact that companies are using AI and earning money as a result.

3.5 BUSINESS ANALYTICS Business analytics is a term used for sophisticated forms of business data analysis. Analytics closely resembles statistical analysis and data mining, but tends to be based on physics modeling involving extensive computation. Example: A common application of business analytics is portfolio analysis. Let us take a case of a bank or lending agency which has a collection of accounts, some from wealthy people, some from middle class people, and some from poor people. The question is how to evaluate the whole portfolio. The bank can make money by lending to wealthy people, but there are only few wealthy people. The bank can make more money by also lending to middle class people. The bank can make even more money by lending to poor people. 101

Information Systems

Note that poorer people are usually at greater risk of default. Note too, that some poor people are excellent borrowers. Note too, that a few poor people may eventually become rich, and will reward the bank for loyalty. The bank wants to maximize its income, while minimizing its risk, which makes the portfolio hard to understand. The analytics solution may combine time series analysis, with many other issues in order to make decisions on when to lend money to these different borrower segments, or decisions on the interest rate charged to members of a portfolio segment to cover any losses among members in that segment. Business analytics as Change Manager: The best hedge against an uncertain future is figuring out how to avoid being surprised when the unexpected happens. Better yet, business executives need to be able to quickly take advantage of changing conditions with new products and services. To accomplish these somewhat elusive goals, companies must constantly improve their ability to identify, classify, and intelligently analyse all available information. A company’s enterprise-information assets — particularly customer data — can be vast, but all too often they're squirreled away in application silos. The marketing department has customer demographics; the accounting department oversees purchase histories, payment frequency, and contract terms; and the customer-service department maintains problem reports. Web sites are adding to the mounds of customer data that companies have to deal with. Web managers can monitor click stream log files to identify how customers navigate a site, where they came from, how long they were there, what they purchased, and where they headed afterward. The goal of high-end business analytics is to turn these individually useful but often marginalized data resources into something that lets business managers immediately grasp the dynamic state of their business. This includes the current and projected status of their customers by group and individual needs. Ideally, analytics lets companies combine demographic and behavioural data with sales information to determine how best to leverage the customer relationship. A company’s ultimate goal is to precisely target new and existing goods to those individuals and groups based on the profiles gleaned from the analytic process. Corporate decision makers need to be increasingly attuned to business opportunities that arise whenever a customer, business, or industry factor changes. Exploiting change is the role of business analytics. Most companies have Web-log data that’s sparse and discrete and a wealth of transaction data, in some cases going back 20 years or more, that’s rich and continuous. The nirvana here, is to integrate these data sources in a meaningful way so a company can tell what its customers are doing now and have done in the past. Business analysts can take that data, do a little trend analysis, and decide how best to pitch new products to customers. There are costs associated with integrating all this data. The investment in gathering the data and aggregating it in meaningful ways must yield a quantifiable business benefit. You can gather all kinds of information, but if you don’t have context, if you don’t advance a business hypothesis and generate a good strategy, it’s pretty much worthless information.

102

Reviewing historical and current data over time can optimally yield enough trend information to feed statistical models that let trained users predict events and trends. However, there’s a reticence on the part of decision makers to trust “black box” business models used by consultants and in some software tools without understanding the parameters being measured.

Intelligence Information Systems

Most of the data is extremely diverse and often in a constant state of flux, so there’s usually no single, specific analytic technique appropriate to your data at a particular stage of its evolution. The upshot is that predictive models must be appropriate to the task, highly customized to specific business conditions, and targeted to address specific areas of interest or answer particular questions. Rather than just having high-end modeling at one end of the spectrum and static reports at the other, what's needed is analytics and analytic applications that watch for change and initiate actions at both an individual and a group level. Analytics are most useful when the application proactively lets the right people know when relevant business factors change. One way of spotting trends is to be able to measure just the part of the business that’s changing. The future level of a lake can be predicted based on how much water is going in and how much is going out. The same analogy applies to business customers. It has been observed that half of companies perform daily data warehouse updates, 40% have weekly or monthly updates, and 10% have real-time or near-real-time updates. It has also been observed that many of the companies performing weekly or monthly updates are apt to shift en masse to performing daily or continuous updates as a result of evolving market and competitive conditions. The need to act upon information is a key driver of high-end analytic applications. Folding business intelligence back into the business decision-making process, operational systems, or human interaction is the primary way to make sure that a company can respond appropriately to changes in customer and market conditions. To bring about this organisational dynamic, the analytic results must be available to all of the people within a company. Traditionally, a lot of information gleaned from a company's business-intelligence tools went to upper management, but it didn't percolate quickly down into the trenches where it could be acted upon by the rank and file. However, the percolated information needs to be based on customization for the company, as company may not like to send all information to every employee. Business analytics is moving beyond data warehousing, which a limited number of experts usually use, to include other components, such as publish-and-subscribe technology to distribute market intelligence to the various employees who need it. If certain events happen, the affected parties are notified in a timely fashion. This represents a kind of opting-in capability for specific kinds of information that helps mid-and low-level decision makers more quickly get the data they need to take action. Improved search and text-mining techniques are aiding the quest for timely information. Predictive modeling applies in this scenario as well. This form of business modeling can help present information based on particular users' past interests and help predict what a manager might want or need to know in the future. It’s all well and good to have a group of statisticians sitting in their ivory cubicles, and it's quite true that companies still need those people to do the data mining today. But if business intelligence is to be more widely used across the enterprise, people must be able to act upon it in a timely fashion and fold the information back into the business process. Critical information about the state of the business must be distributed

103

Information Systems

quickly, efficiently, and appropriately to those people and departments that can affect the company’s adaptability. These are goals that IT departments have avidly pursued but have hitherto never been able to grasp fully. Fortunately, today’s advanced analytics tools point to a time when compiling data, monitoring near-real-time business events, and synthesizing that data via data-mining and other advanced techniques will let companies respond almost immediately to perceived or predicted changes in market conditions. Early versions of these tools already let companies make business forecasts, optimize resources on the fly, and suggest appropriate actions with unprecedented speed, agility, and accuracy. Companies should look twice at implementing traditional business-intelligence solutions and look more toward solutions that deliver analytics at the point of a business process. A classic example of this is seen in inventory reordering systems based on supply-anddemand forecasts. Market data is fed back into the system to determine where, when, and how much inventory should be reordered. This type of analysis results directly in a modification of the business processes. The trick is to incorporate this intelligence into both tactical and strategic decision-making with managers making real-time decisions. The latest challenge in business analytics is to capture external data from sources that companies haven’t really considered before. If there’s a cliché in the making here, it’s that data abounds, but knowledge acquisition takes a lot more work. Many alternate sources of data are available via the Web. The number of customer-data sources continues to expand dramatically. The key will be to determine which of these data points are more relevant and to figure out organisational processes that will permit appropriate data to be fed to the analytics engine so a company or department can respond to it in real time and feed it into ongoing projects, sales efforts, and marketing campaigns. Neural networks are flexible models that can be applied to predictive analysis and pattern-recognition problems. You want to control for different factors and see what's working for you and what's giving you the most bang for your buck. Well-targeted analytics will provide yield indicators and trends that the company can exploit to its advantage. Another trend that we're seeing is a kind of cross-disciplinary awareness. Companies that have statisticians with different bases of experience or analysts who are able to make analogies more easily than most of us have recognised that there are large data issues in fields such as genomics. Both genetic researchers and companies with terabyte-level customer-relationship management systems share some common data management issues. Each group could learn from the other and share common analytical approaches. Another way business-intelligence tools are evolving is in interactive analytics, in which users are able to slice and dice data and also carry out what-if scenarios. Instead of driving the enterprise by looking in the rearview mirror, you’re looking forward to what might happen and can strategize on how to reach that outcome. Interactive analytics is an area where many conventional business-analytical tools fall short. Organisations want a single view of the customer, particularly given current economic trends. This requires a move away from point solutions to more integrated systems. It’s a giant problem to access all of the disparate data sources scattered around the organisation. The reason it’s a giant problem is that many companies wouldn’t even know what to do with it once it’s in one place.

104

This was characteristic of the naiveté of early data warehouse projects in the 1990s— many of which failed. “We’re seeing much more sophistication around the way highend business analytics are approached today, We don’t really just want to bring a lot of data together; we actually want to work backward from the questions we’re trying to answer.”

Intelligence Information Systems

There’s also the issue of corporate management developing a level of trust in advanced analytical tools. Being comfortable with driving their business based on associations that aren’t easily visible to the human eye doesn’t come easily to many CEOs and business managers. As well, many VPs and marketing managers approach marketing as more of an art than a science and are somewhat resistant to analytic technologies. The acceptance problem is twofold. The tools and techniques are still complex and difficult to use. Companies require the guys with the lab coats to make these tools hum. The analytic results that derive from them are often barely auditable, especially when employing things such as neural networks. The sheer sophistication of the tools makes it difficult for business managers to understand how the software came to a particular conclusion. As a result, decision makers often feel uncomfortable implementing results from analysis that they can’t audit, figure out what the assumptions are, and how the results were derived. Trust will emerge when people take a couple of these recommendations, implement them, and see a positive impact on the bottom line. The ultimate outcome of high-end analytics will be systems that can process diverse business data, draw conclusions, and alert managers to proposed actions and outcomes. Hopefully, the impact on business will be companies that are more agile and better informed about all the conditions both within and outside their corporate boundaries. Available Business Analytics: Such suits are being offered by several vendors. Vendors claim that these suits identify trends, perform comparisons and highlight opportunities in various business functions like supply chain management, even when large amounts of data are involved. These suits combine technology with human effort and help decision-makers in business areas such as sourcing, inventory management, manufacturing, quality, sales and logistics. Business Analytics solutions leverage investments made in enterprise applications, web technologies, data warehouses and information obtained from external sources to locate patterns among transactional, demographic and behavioural data. Vendors claim that with wafer-thin margins, managing costs is an ongoing challenge. Business analytics solutions being offered can help managers in sales, marketing, customer support, supply chain planning and financials understand and respond to key issues, such as: •

Correctly analysing barriers to market-entry, this varies widely with each product,

•

Responding to competition within a well defined supply tier structure,

•

Dealing with the high threat of product substitutes,

•

Continually driving product innovation,

•

Managing product lifecycles to maximize returns.

3.6 BUSINESS INTELLIGENCE The term business intelligence (BI) typically refers to a set of business processes for collecting and analyzing business information. This includes the technology used in these processes, and the information obtained from these processes. BI business processes Organisations typically gather information in order to assess the business environment, and cover fields such as marketing, research, industry or market research, and competitor analysis. Competitive organisations accumulate business intelligence in order to gain sustainable competitive advantage, and may regard such intelligence as a valuable core competence in some instances. Generally, BI-collectors glean their primary information from internal business sources. Such sources help decision-makers understand how well they have performed. Secondary sources of information include customer needs, customer decision-making processes, the competition and competitive pressures, conditions in relevant industries, and general economic, technological, and cultural trends. Industrial espionage may also provide business intelligence by using covert techniques. A gray area exists between “normal” business intelligence and industrial espionage. Each business intelligence system has a specific goal, which derives from an organisational goal or from a vision statement. Both short-term goals (such as quarterly numbers to share market) and long term goals (such as shareholder value, target industry share / size, etc.) exist. 110

BI technology Some observers regard BI as the process of enhancing data into information and then into knowledge. Persons involved in business intelligence processes may use application software and other technologies to gather, store, analyze, and provide access to data, and present that data in a simple, useful manner. The software aids in Business performance management, and aims to help people make "better" business decisions by making accurate, current, and relevant information available to them when they need it.

Intelligence Information Systems

Some people use the term “BI” interchangeably with “briefing books” or with “executive information systems”, and the information that they contain. In this sense, one can regard a business intelligence system as a decision-support system (DSS). BI software types People working in business intelligence have developed tools that ease the work, especially when the intelligence task involves gathering and analyzing large quantities of unstructured data. Each vendor typically defines Business Intelligence his/her own way, and markets tools to do BI the way that they see it. Business intelligence includes tools in various categories, including the following: • • • • • • • • • • • • • • • • • • • • • • • • • •

AQL - Associative Query Logic Scorecarding Business Performance Management and Performance Measurement Business Planning Business Process Re-engineering Competitive Analysis Customer Relationship Management (CRM) and Marketing Data mining (DM), Data Farming, and Data warehouses Decision Support Systems (DSS) and Forecasting Document warehouses and Document Management Enterprise Management systems Executive Information Systems (EIS) Finance and Budgeting Human Resources Knowledge Management Mapping, Information visualization, and Dashboarding Management Information Systems (MIS) Geographic Information Systems (GIS) Online Analytical Processing (OLAP) and multidimensional analysis; sometimes simply called Analytics (based on the so-called hypercube or cube) Statistics and Technical Data Analysis Supply Chain Management/Demand Chain Management Systems intelligence Trend Analysis User/End-user Query and Reporting Web Personalization and Web Mining Text mining.

History Prior to the start of the Information Age in the late 20th century, businesses sometimes struggled to collect data from non-automated sources. Businesses then lacked the computing resources to properly analyze the data, and often made business decisions primarily on the basis of intuition. As businesses started automating more and more systems, more and more data became available. However, collection remained a challenge due to a lack of infrastructure for 111

Information Systems

data exchange or to incompatibilities between systems. Analysis of the data that was gathered and reports on the data sometimes took months to generate. Such reports allowed informed long-term strategic decision-making. However, short-term tactical decision-making continued to rely on intuition. In modern businesses, increasing standards, automation, and technologies have led to vast amounts of data becoming available. Data warehouse technologies have set up repositories to store this data. Improved Extract, transform, load (ETL) and even recently Enterprise Application Integration tools have increased the speedy collecting of data. OLAP reporting technologies have allowed faster generation of new reports which analyze the data. Business intelligence has now become the art of sieving through large amounts of data, extracting pertinent information, and turning that information into knowledge upon which actions can be taken. Business intelligence software incorporates the ability to data mine, analyze, and report. Some modern BI software allow users to cross-analyze and perform deep data research rapidly for better analysis of sales or performance on an individual, department, or company level. In modern applications of business intelligence software, managers are able to quickly compile reports from data for forecasting, analysis, and business decision making. Indicators BI often uses Key performance indicators (KPIs) to assess the present state of business and to prescribe a course of action. More and more organisations have started to make more data available more promptly. In the past, data only became available after a month or two, which did not help managers to adjust activities in time to hit Share Market targets. Recently, banks have tried to make data available at shorter intervals and have reduced delays. The KPI methodology was further expanded with the Chief Performance Officer methodology which incorporated KPIs and root cause analysis into a single methodology. KPI example For example, for businesses which have higher operational/credit risk loading (for example, credit cards and "wealth management"), a large multi-national bank makes KPI-related data available weekly, and sometimes offers a daily analysis of numbers. This means data usually becomes available within 24 hours, necessitating automation and the use of IT systems. Designing and implementing a business intelligence programme When implementing a BI programme one might like to pose a number of questions and take a number of resultant decisions, such as:

112

â&#x20AC;˘

Goal Alignment queries: The first step determines the short and medium-term purposes of the programme. What strategic goal(s) of the organisation will the programme address? What organisational mission/vision does it relate to? A crafted hypothesis needs to detail how this initiative will eventually improve results / performance (i.e., a strategy map).

â&#x20AC;˘

Baseline queries: Current information-gathering competency needs assessing. Does the organisation have the capability of monitoring important sources of information? What data does the organisation collect and how does it store that data? What are the statistical parameters of this data, e.g., how much random variation does it contain? Does the organisation measure this?

•

Cost and risk queries: The financial consequences of a new BI initiative should be estimated. It is necessary to assess the cost of the present operations and the increase in costs associated with the BI initiative. What is the risk that the initiative will fail? This risk assessment should be converted into a financial metric and included in the planning? Customer and Stakeholder queries: Determine who will benefit from the initiative and who will pay. Who has a stake in the current procedure? What kinds of customers/stakeholders will benefit directly from this initiative? Who will benefit indirectly? What are the quantitative / qualitative benefits? Is the specified initiative the best way to increase satisfaction for all kinds of customers, or is there a better way? How will customers’ benefits be monitored? What about employees? shareholders? and distribution channel members?

•

Metrics-related queries: These information requirements must be operationaged zed into clearly defined metrics. One must decide what metrics to use for each piece of information being gathered. Are these the best metrics? How do we know that? How many metrics need to be tracked? If this is a large number (it usually is), what kind of system can be used to track them? Are the metrics standardized, so they can be benchmarked against performance in other organisations? What are the industry standard metrics available?

•

Measurement Methodology-related queries: One should establish a methodology or a procedure to determine the best (or acceptable) way of measuring the required metrics. What methods will be used, and how frequently will the organisation collect data? Do industry standards exist for this? Is this the best way to do the measurements? How do we know that?

•

Results-related queries: Someone should monitor the BI programme to ensure that objectives are being met. Adjustments in the programme may be necessary. The programme should be tested for accuracy, reliability, and validity. How can one demonstrate that the BI initiative (rather than other factors) contributed to a change in results? How much of the change was probably random?.

3.7 ROLE OF BUSINESS INTELLIGENCE The information economy puts a premium on high quality actionable information — exactly what Business Intelligence (BI) tools like data warehousing, data mining, and OLAP can provide to the business. A close look at the different organisational functions suggests that BI can play a crucial role in almost every function. It can give new and often surprising insights about customer behavior; thereby helping the businesses meeting their ever-changing needs and desires. On the supply side, BI can help businesses to identify their best vendors and determine what separates them from not so good vendors. It can give businesses better understanding of inventory and its movement and also help improve production and storefront operations through better category management. Through a host of analyses and reports, BI can also improve internal organisational support functions like finance and human resource management of any business. Business Intelligence is applicable to all types of businesses; however, the magnitude of gains may vary. Here we will discuss in detail how BI can improve the key functional areas and thereby the overall productivity of the business.

3.7.1

Marketing

Smart Businesses in their efforts to meet the competition have reoriented their business around the customer by improving Customer Relationship Management. In the mad rush to acquire new customers, they have realized it is equally important to 113

Information Systems

retain the existing ones. Increased interaction and sophisticated analysis techniques have given businesses unprecedented access to the mind of the customer; and they are using this to develop one-to-one relation with the customer, design marketing and promotion campaigns, optimize sale front layout, and manage e-commerce operations. For improving Customer Relationship Management (CRM), the CRM strategy needs to include: • •

Operational CRM: Automating interaction with the customers and sales force, Analytical CRM: Sophisticated analysis of the customer data generated by operational CRM and other sources like Sales Orders transactions, web site transactions, and third-party data providers.

A typical business organisation has a huge customer base and often customer's needs are fairly varying. Without the means to analyze voluminous customer data, CRM strategy is bound to be a failure, therefore, the Analytical CRM forms the core of the customer relationship strategy of a business. Marketing and sales functions are the primary beneficiaries of Analytical CRM and the main touch points from where the insights gained about the customer is absorbed in the organisation. Analytical CRM uses key business intelligence tools like data warehousing, data mining, and OLAP to present a unified view of the customer. Following are some of the uses of Analytical CRM: •

Customer Classification: Customer classification is a vital ingredient in a business organisation's marketing strategy. It can offer insights into how different segments respond to shifts in demographics, fashions and trends. For example it can help classify customers in the following segments: a) b) c) d)

•

Campaign / Marketing Promotion Effectiveness Analysis: Once a campaign is launched, its effectiveness can be studied across different media and in terms of costs and benefits; this greatly helps in understanding what goes into a successful marketing campaign. Campaign/ promotion effectiveness analysis can answer questions such as: a) b) c) d)

•

114

Customers who respond to new promotions Customers who respond to new product launches Customers who respond to discounts Customers who show a tendency to purchase specific products.

Which media channels have been most successful in the past for various campaigns? Which geographic locations responded well to a particular campaign? What were the relative costs and benefits of this campaign? Which customer segments responded to the campaign?

Customer Lifetime Value: Not all customers are equally profitable. At the same time customers who are not very profitable today may have the potential of being profitable in future. Hence, it is absolutely essential to identify customers with high lifetime value; the idea is to establish long-term relations with these customers. The basic methodology used to calculate customer lifetime value is to deduct the cost of servicing a customer from the expected future revenue generated by the customer, add to this the net value of new customers referred by this customer, and discount the result for the duration of the relationship. Though this sounds easy, there are a number of subjective variables like overall duration of the

customer's relation with the business, gap between intermediate cash flows, and discount rate. It is suggested that data mining tools should be used to develop customized models for calculating customer lifetime value.

3.7.2

Customer Loyalty Analysis: It is more economical to retain an existing customer than to acquire a new one. To develop effective customer retention programs it is vital to analyze the reasons for customer attrition. Business Intelligence helps in understanding customer attrition with respect to various factors influencing a customer and at times one can drill down to individual transactions, which might have resulted in the change of loyalty.

Cross Selling: Businesses use the vast amount of customer information available with them to cross sell other products at the time of purchase. This effort is largely based on the tastes of a particular customer, which can be analyzed using BI tools based on previous purchases. Businesses can also â&#x20AC;&#x2DC;up sellâ&#x20AC;&#x2122; - sell more profitable products - to the customer at the time of contact.

Product Pricing: Pricing is one of the most crucial marketing decisions taken by businesses. Often an increase in price of a product can result in lower sales and customer adoption of replacement products. Using data warehousing and data mining, businesses can develop sophisticated price models for different products, which can establish price - sales relationships for the product and how changes in prices affect the sales of other products.

Target Marketing: Businesses can optimize the overall marketing and promotion effort by targeting campaigns to specific customers or groups of customers. Target marketing can be based on a very simple analysis of the buying habits of the customer or the customer group; but increasingly data mining tools are being used to define specific customer segments that are likely to respond to particular types of campaigns.

Intelligence Information Systems

Sales and Orders

The success of a business in the future would depend on how effectively it manages multiple delivery channels like the Internet, interactive TV, catalogs, etc. A single customer is likely to interact with the retailer along multiple channels over a period of time. This calls for an integrated strategy to serve the customer well, which requires smooth flow of information across channels. To ensure smooth flow of information customer data needs to be collected from different channels in one data warehouse. Customer relationship strategy can then be built around this customer-centric data warehouse. We have already discussed how Analytical CRM can provide analyses over the centralized data warehouse. In this section we will explore how data warehousing and data mining can improve the effectiveness of a channel. â&#x20AC;˘

E-Business Analysis: The Internet has emerged as a powerful alternative channel for established sales methods. Increasing competition from businesses operating purely over the Internet has forced the businesses who had not adopted this route to quickly adopt this channel. Their success would largely depend on how they use the Net to complement their existing channels. Web logs and Information forms filled over the web are very rich sources of data that can provide insightful information about customer's browsing behavior, purchasing patterns, likes and dislikes, etc. Two main types of analysis done on the web site data are:

115

Information Systems

3.7.3

Web Log Analysis: This involves analyzing the basic traffic information over the e-commerce web site. This analysis is primarily required to optimize the operations over the Internet. It typically includes following analyses: •

Site Navigation: An analysis of the typical route followed by the user while navigating the web site. It also includes an analysis of the most popular pages in the web site. This can significantly help in site optimization by making it more user- friendly.

•

Referrer Analysis: An analysis of the sites, which are very prolific in diverting traffic to the company’s web site.

•

Error Analysis: An analysis of the errors encountered by the user while navigating the web site. This can help in solving the errors and making the browsing experience more pleasurable.

•

Keyword Analysis: An analysis of the most popular keywords used by various users in Internet search engines to reach the concerned business e-commerce web site.

Web Housing: This involves integration of web log data with data from other sources like the purchase order transactions, third party data vendors etc. Once the data is collected in a single customer centric data warehouse, often referred to as Web house, all the applications already described under CRM can be implemented. Often a business wants to design specific campaigns for users who purchase from the e-commerce web site. In this case, segmentation and profiling can be done specifically for the .ecustomers to understand their needs and browsing behavior. It can also be used to personalize the content of the e-commerce web site for these users.

Channel Profitability: Data warehousing can help analyze channel profitability, and whether it makes sense for the business to continue building up expertise in the channel. The decision of continuing with a channel would also include a number of subjective factors like outlook of key enabling technologies for that channel.

Product Channel Affinity: Some product categories sell particularly well on certain channels. Data warehousing can help identify hidden productchannel affinities and help the business design better promotion and marketing campaigns.

Human Resource

Data warehousing can significantly help in aligning the HR strategy to the overall business strategy. It can present an integrated view of the workforce and help in designing retention schemes, improve productivity, and curtail costs. Some BI applications in HR are: •

116

Human Resource Reports/ Analytics: Reports and analysis can be generated to support an integrated view of the workforce. Various analyses include staff movement and performance, workforce attrition by business, workforce performance by business, compensation and attrition, and other customized analyses and reports. The HR data can be integrated with benchmark figures for the industry and various reports can be generated to measure performance vis-àvis industry benchmarks.

•

Manpower Allocation: This includes allocating manpower based on the demand projections. According to the seasonal variation in demand, temporary manpower can be hired to maintain service levels. The demand levels vary within one working day also, which can be used to allocate resources accordingly.

•

HR Portal: Employers need to maintain accurate employee data, which can be viewed by the employees for information relating to compensation, benefits, retirement facilities, etc. Payroll data can be integrated with data from other human resource management applications in the HR data warehouse. This data can then be circulated within the organisation through the HR portal.

•

Training and Succession Planning: Accurate data about the skill sets of the workforce can be maintained in the data warehouse. This can be used to design training programs and for effective succession planning.

3.7.4

Finance and Accounts

The role of financial reporting has undergone a paradigm shift during the last decade. It is no longer restricted to just financial statements required by the law; increasingly it is being used to help in strategic decision making. Also, many organisations have embraced a free information architecture, whereby financial information is openly available for internal use. Many analytics described till now use financial data. Many companies, across industries, have integrated financial data in their enterprise wide data warehouse or established separate Financial Data Warehouse (FDW). Following are some of the uses of BI in finance: •

Budgetary Analysis: Data warehousing facilitates analysis of budgeted versus actual expenditure for various cost heads like promotion campaigns, energy costs, salary, etc. OLAP tools can provide drill down facility whereby the reasons for cost overruns can be analyzed in more detail. It can also be used to allocate budgets for the coming financial period.

•

Fixed Asset Return Analysis: This is used to analyse financial viability of the fixed assets owned or leased by the company. It would typically involve measures like profitability per sq. foot of the space, total lease cost vs. profitability, etc.

•

Financial Ratio Analysis: Various financial ratios like debt-equity, liquidity ratios, etc. can be analyzed over a period of time. The ability to drill down and join inter-related reports and analyses provided by all major OLAP tool vendors can make ratio analysis much more perceptive.

•

Profitability Analysis: This includes profitability of individual business, departments within the business, product categories, brands, and individual SKUs. A major component of profitability analysis is the costs incurred by departments and the cost of acquiring, storing and allocating shelf space to particular product categories, brands, or SKUs. It goes without saying that profitability analysis has an extremely universal appeal and would be required by other groups within the business organisation.

Same as these Business tool is being discussed in detail in the following unit: On Line Analytical Processing (OLAP) OLAP is an acronym for On Line Analytical Processing. It is an approach to quickly provide the answer to analytical queries that are multi-dimensional in nature. It is part of the broader category business intelligence, which also includes ETL (Extract, Transform, Load), relational reporting and data mining. The typical applications of OLAP are in business reporting for sales, marketing, management reporting, business performance management (BPM), budgeting and forecasting, financial reporting and similar areas. The term OLAP was created as a slight modification of the traditional database term OLTP (On Line Transaction Processing). Databases configured for OLAP employ a multidimensional data model, allowing for complex analytical and ad-hoc queries with a rapid execution time. Nigel Pendse has suggested that an alternative and perhaps more descriptive term to describe the concept of OLAP is Fast Analysis of Shared Multidimensional Information (FASMI). They borrow aspects of navigational databases and hierarchical databases that are speedier than their relational kin. OLAP Functionality OLAP takes a snapshot of a set of source data and restructures it into an OLAP cube. The queries can then be run against this. It has been claimed that for complex queries OLAP can produce an answer in around 0.1% of the time for the same query on OLTP relational data. The cube is created from a star schema or snowflake schema of tables. At the centre is the fact table which lists the core facts which make up the query. Numerous dimension tables are linked to the fact tables. These tables indicate how the aggregations of relational data can be analyzed. The number of possible aggregations is determined by every possible manner in which the original data can be hierarchically linked. For example a set of customers can be grouped by city, by district or by country; so with 50 cities, 8 districts and two countries there are three hierarchical levels with 60 members. These customers can be considered in relation to products; if there are 250 products with 20 categories, three families and three departments then there are 276 product members. With just these two dimensions there are 16,560 (276 * 60) possible aggregations. As the data considered increases the number of aggregations can quickly total tens of millions or more. The calculation of the aggregations and the base data combined make up an OLAP cube, which can potentially contain all the answers to every query which can be answered from the data. Due to the potentially large number of aggregations to be calculated, often only a predetermined number are fully calculated while the remainder are solved on demand.

119

Information Systems

Types of OLAP There are three types of OLAP. Multidimensional OLAP MOLAP is the ‘classic’ form of OLAP and is sometimes referred to as just OLAP. MOLAP uses database structures that are generally optimal attributes such as time period, location, product or account code. The way that each dimension will be aggregated is defined in advance by one or more hierarchies. Relational OLAP ROLAP works directly with relational databases.The base data and the dimension tables are stored as relational tables and new tables are created to hold the aggregated information. Hybrid OLAP There is no clear agreement across the industry as to what constitutes "Hybrid OLAP", except that a database will divide data between relational and specialized storage. For example, for some vendors, a HOLAP database will use relational tables to hold the larger quantities of detailed data, and use specialized storage for at least some aspects of the smaller quantities of more-aggregate or less-detailed data. Comparison Each type has certain benefits, although there is disagreement about the specifics of the benefits between providers. MOLAP is better on smaller sets of data, it is faster to calculate the aggregations and return answers and needs less storage space. ROLAP is considered more scalable. However, large volume pre-processing is difficult to implement efficiently so it is frequently skipped. ROLAP query performance can therefore suffer. HOLAP is between the two in all areas, but it can pre-process quickly and scale well. All types though are prone to database explosion. Database explosion is a phenomenon causing vast amount of storage space being used by OLAP databases when certain but frequent conditions are met: high number of dimensions, precalculated results and sparse multidimensional data. The difficulty in implementing OLAP comes in forming the queries, choosing the base data and developing the schema, as a result of which most modern OLAP products come with huge libraries of pre-configured queries. Another problem is in the base data quality - it must be complete and consistent. Other types The following acronyms are also used sometimes, although they are not as widespread as the ones above • •

WOLAP - Web-based OLAP DOLAP - Desktop OLAP RTOLAP - Real-Time OLAP.

APIs and query languages Unlike relational databases - which had SQL as the standard query language and widespread APIs such as ODBC, JDBC and OLEDB - there was no such unification in the OLAP world. The first real standard API was OLEDB for OLAP specification from Microsoft which appeared in 1997 and introduced the MDX query language. Several OLAP vendors - both server and client - adopted it. In 2001 Microsoft and Hyperion announced the XML for Analysis specification, which was endorsed by most of the 120

OLAP vendors. Since this also used MDX as a query language, MDX became the defacto standard in the OLAP world.

Data mining Data Mining, also known as Knowledge-Discovery in Databases (KDD), is the process of automatically searching large volumes of data for patterns.. Data Mining can be defined as “The nontrivial extraction of implicit, previously unknown, and potentially useful information from data and The science of extracting useful information from large data sets or databases.” Although it is usually used in relation to analysis of data, data mining, like artificial intelligence, is an umbrella term and is used with varied meaning in a wide range of contexts. It is usually associated with a business or other organisation’s need to identify trends. Data mining involves the process of analyzing data to show patterns or relationships and sorting through large amounts of data and picking out pieces of relative information or patterns that occur e.g. picking out statistical information from some data. A simple example of data mining is its use in a retail sales department. If a store tracks the purchases of a customer and notices that a customer buys a lot of silk shirts, the data mining system will make a correlation between that customer and silk shirts. The sales department will look at that information and may begin direct mail marketing of silk shirts to that customer, or it may alternatively attempt to get the customer to buy a wider range of products. In this case, the data mining system used by the retail store discovered new information about the customer that was previously unknown to the company. Another widely used (though hypothetical) example is that of a very large North American chain of supermarkets. Through intensive analysis of the transactions and the goods bought over a period of time, analysts found that beers and diapers were often bought together. Though explaining this interrelation might be difficult, taking advantage of it, on the other hand, should not be hard (e.g., placing the high-profit diapers next to the high-profit beers). This technique is often referred to as Market Basket Analysis In statistical analyses, in which there is no underlying theoretical model, data mining is often approximated via stepwise regression methods wherein the space of 2k possible relationships between a single outcome variable and k potential explanatory variables is smartly searched. With the advent of parallel computing, it became possible (when k is less than approximately to examine all 2k models.) This procedure is called all subsets or exhaustive regression. Some of the first applications of exhaustive regression involved the study of plant data. Data dredging Used in the technical context of data warehousing and analysis, the term “data mining” is neutral. However, it sometimes has a more pejorative usage that implies imposing patterns (and particularly causal relationships) on data where none exist. This imposition of irrelevant, misleading or trivial attribute correlation is more properly criticized as “data dredging” in statistical literature. Another term for this misuse of statistics is data fishing.

121

Information Systems

Used in this latter sense, data dredging implies scanning the data for any relationships, and then when one is found coming up with an interesting explanation. (This is also referred to as “over fitting the model”.) The problem is that large data sets invariably happen to have some exciting relationships peculiar to that data. Therefore, any conclusions reached are likely to be highly suspect. In spite of this, some exploratory data work is always required in any applied statistical analysis to get a feel for the data, so sometimes the line between good statistical practice and data dredging is less than clear. One common approach to evaluating the fitness of a model generated via data mining techniques is called cross validation. Cross validation is a technique that produces an estimate of generalization error based on resampling. In simple terms, the general idea behind cross validation is that dividing the data into two or more separate data subsets allows one subset to be used to evaluate the generalize ability of the model learned from the other data subset(s). A data subset used to build a model is called a training set; the evaluation data subset is called the test set. Common cross validation techniques include the holdout method, k-fold cross validation, and the leave-one-out method. Another pitfall of using data mining is that it may lead to discovering correlations that may not exist. “There have always been a considerable number of people who busy themselves examining the last thousand numbers which have appeared on a roulette wheel, in search of some repeating pattern. Sadly enough, they have usually found it.” However, when properly done, determining correlations in investment analysis has proven to be very profitable for statistical arbitrage operations (such as pairs trading strategies), and furthermore correlation analysis has shown to be very useful in risk management. Indeed, finding correlations in the financial markets, when done properly, is not the same as finding false patterns in roulette wheels. Most data mining efforts are focused on developing highly detailed models of some large data set. Other researchers have described an alternate method that involves finding the minimal differences between elements in a data set, with the goal of developing simpler models that represent relevant data. Notable uses of data mining •

Data mining has been cited as the method by which the U.S. Army unit Able Danger supposedly had identified the 9/11 attack leader, Mohamed Atta, and three other 9/11 hijackers as possible members of an al Qaeda cell operating in the U.S. more than a year before the attack.

Business performance management Business performance management (BPM) is a set of processes that help organisations optimize business performance. BPM is seen as the next generation of business intelligence (BI). BPM is focused on business processes such as planning and forecasting. It helps businesses discover efficient use of their business units, financial, human, and material resources. 122

BPM involves consolidation of data from various sources, querying, and analysis of the data, and putting the results into practice.

Intelligence Information Systems

BPM enhances processes by creating better feedback loops. Continuous and real-time reviews help to identify and eliminate problems before they grow. BPM's forecasting abilities help the company take corrective action in time to meet earnings projections. Forecasting is characterized by a high degree of predictability which is put into good use to answer what-if scenarios. BPM is useful in risk analysis and predicting outcomes of merger and acquisition scenarios and coming up with a plan to overcome potential problems. BPM provides key performance indicators (KPI) that help companies monitor efficiency of projects and employees against operational targets. Metrics / Key Performance Indicators BPM often uses key performance indicators (KPIs) to assess the present state of business and to prescribe a course of action. More and more organisations have started to make data available more promptly. In the past, data only became available after a month or two, which did not help to suggest to managers that they should adjust activities in time to hit targets. Recently, banks have tried make data available at shorter intervals and have reduced delays. For example, for businesses which have higher operational/credit risk loading (for example, credit cards, A large multi-national bank makes KPI-related data available weekly, and sometimes offers a daily analysis of numbers. This means data usually becomes available within 24 hours, necessitating automation and the use of IT systems. Most of the time, BPM simply means use of several financial/non-financial metrics/key performance indicators to assess the present state of business and to prescribe a course of action. 1)

3.9 BUSINESS INTELLIGENCE REPORTS Reporting is a fundamental business requirement as every transaction-based enterprise application, every database, and each process that workers perform on a day-to-day basis needs reporting in some fashion. Reporting allows the users to access, format, and securely deliver data as meaningful information. The power of Business Objects reporting provides the user with the information they need, when they need it — inside and outside the organisation. Reporting and analysis have become persistent in business, and they must be seen as a core requirement and be held to the same standards as all core technologies. The reporting and analysis market is mature. Companies have a wide variety of technology options, from a plethora of BI vendors to platform and application vendors. The participation by so many vendors reflects two issues: •

Companies want a single BI reporting and analysis solution: Every company and government organisation wants a single, standard reporting and analysis solution for the entire organisation as they need to drive down IT support costs and simultaneously increase the likelihood of a single version of critical data.

•

Vendors want to be selected as the BI reporting and analysis standard: Simply put, the vendor that offers the most comprehensive BI reporting and analysis solution is in a better position of being selected as the reporting standard. To that extent, there has been a significant amount of activity by the vendors during the past years to deliver a broader BI reporting and analysis platform.

Requirements of the Reporting solution are: Powerful Authoring: Business Objects reporting requires a powerful, flexible, and open environment for report creation. You need to connect to any data, and then build highly-formatted reports using intuitive, flexible design tools. In addition, you require the ability to integrate end-user report viewing, printing, exporting, and creation capabilities into applications using a comprehensive set of software developer kits and powerful report processing services. Flexible Sharing: Once a report is created, you need to publish it on the web, portals, printers, email, and applications. In enterprise reporting, Business Objects need to provide a BI platform for secure, highly scalable information delivery to handle large numbers of end users around the world. For embedded reporting, we need to provide open application integration and flexible deployment. Our products are required to integrate tightly with existing infrastructure to meet even the most demanding 124

enterprise and embedded reporting requirements. Reports may be required to be integrated into Java, .NET, and COM applications and deployed on Windows, UNIX, and Linux.

Intelligence Information Systems

Reporting — the Way Users Work: For end users, reports need to include built-in interactivity, creating a clean and efficient process where one report will satisfy the needs of many different individuals. Users need to not only view reports in web portals, but they also need to explore the information by moving easily from static consumption to insightful interaction. What’s more, users may require embedding and securely sharing live reports or parts of reports inside Microsoft Office Word, PowerPoint, and Excel documents. Proven Technology: The vendor needs to adopt proven technology which has evolved over time to become the de facto accepted standard for reporting. It should have compatibility with leading enterprise application software like SAP, IBM, Microsoft, Oracle/PeopleSoft, Borland, and BEA. Types Of Reporting and Analysis Solutions: There are three types of solutions available as shown below. Some of the vendors who supply solutions have also been indicated. At its core, reporting technology is required to be designed for information distribution. Whether it’s ad-hoc or predefined, the reporting paradigm have to address the information delivery, publishing and distribution. That is why reporting products generally have menu items that predefine the query, format the resulting data and then publish that report to the people it was designed for. When describing BI technologies, reporting is often lumped together with analysis to categorize a technology as “reporting and analysis.” This makes some sense because analysis is what users ultimately do with a report once it is received. If the user knows ahead of time what data is needed and considers the job complete once the report has been published, then reporting technology is the right tool for the job. Every information consumer in the organisation, from executives to production workers, will use these reporting systems. However, if the user’s job is to make decisions, this “delivery” model may only be adequate in certain circumstances and be significantly inadequate in others. The most popular feature in any reporting system is the “Export to Excel” button simply because the decision maker’s job with the data is not done when the information is delivered the job has just begun. Using the Repository for More Productive Report Development Many report designers keep a set of reports that contain pieces of reports that they would use over and over. In many cases, these reports would contain corporate logos, commonly used objects (like a company’s address), and even some typical formula logic. Report designers copy and paste these objects between these “warehouse reports” and the newly created reports on a regular basis. This technique saves the designer some time, as they do not have to recreate these objects for each new report. But, what happens when business logic changes and needs to be updated? This happens quite often and is a critical piece of the reporting puzzle. The only tried-andtrue method of the past does not solve the problem of how to update business logic or formulas in reports that has already been created. The report designer has to remember which reports may have been affected, open each individual report, and update them by hand-coding the changes. This process is cumbersome and time-consuming but mission critical. One common location to store and update report objects can dramatically improve this situation. 125

Information Systems

For accomplishing improvement of the productivity of the report design process a centrally managed location is required so that report designers can access, update, reuse and share report objects. To extend this concept, report objects can also be shared and reused among multiple report designers for even greater efficiency. The Repository is a central database that contains common report objects that can be shared and reused. The types of report objects that can be shared via the repository are: • • • •

Text Objects: Reusable text, such as company addresses or confidentiality statements Images: Pictures or logos Custom Functions: Business logic that can be reused by passing in new fields as variables SQL Commands: Encapsulated database commands that produce tables to report from. These SQL statements can also be parameter driven.

The Repository is independent from all other databases connected to any report. It manages logic, is a standalone database formatting, and objects. But most importantly, by its very nature as a separate library (or database), it is referenced by the report when the report is opened, and, as a result, it can actually update the repository objects automatically for the report designer so that the added overhead of copying new logic and objects is eliminated. To add an object to the Repository, it's as simple as dragging and dropping the object into a folder in the Repository Explorer. The Repository Explorer represents the repository database as a tree structure made up of folders and objects. The structure of the repository folders is up to the person working with the repository. Within the Repository Explorer, the report designer has to have access to the repository objects that can be placed on the report design surface. Text objects and image objects are visible from the Repository Explorer. To use Repository Objects in your reports, simply drag-and-drop these objects on to the report as required. SQL commands and their properties are visible in the Repository Explorer. You do not drag-and-drop these objects on the report as they are used in the Database Expert. You can use SQL Commands like database tables when you're designing your report. You can save your SQL statements in the repository for later use with the SQL Command in Repository feature. Trends Quality reports are critical. It is not a very unusual scene to find that executives arrive at meetings armed with spreadsheets only to find that each has different values for the same metrics. The rest of the meeting is then spent arguing over whose numbers are correct, rather than in actual decision making based on consistent numbers. This malaise is largely an offshoot of data fragmentation, the fracture of a single version of operational truth into multiple data sources, often not correlated with each other. The most significant part of providing quality reports is the choice and architecture of your reporting solution. Quality aside, another important facet of reporting is delivery. Users want reports to be personalized, organised, timely, easily accessible and in their preferred format. For example, in today’s business environment it is desirable to be able to e-mail reports to colleagues, create spreadsheets from report results and access reports securely over the internet. One aspect of reporting that is frequently overlooked is its integration with other IT infrastructure elements. We have seen some customer departments so completely 126

focused on “solving the reporting problem” — evaluating checklists of features from various vendors, reading analyst reports on each vendors – that they fail to coordinate this effort with the bigger company wide picture of how that reporting piece fits into other infrastructure (such as the central security repository or caching strategy). These customers then find themselves in the position of having to stitch together their data warehouse, reporting, security and portal solutions and own the problem of identifying the correct vendor to call.

4.0 INTRODUCTION The information systems, Internet and the World Wide Web have grown rapidly and are now used by millions of people worldwide. Their importance in every day life is well known, however, it is also important to realise that the information systems and Web are what we make them and the code of ethics and morals we apply on these. The Objective of this unit is to make all students familiar with the negative aspects of information systems. The issues related to morals, ethics and privacy of information and action and the security of information systems are, increasingly, a focus of concern for the business community and the public at large. Accordingly, ethics, morals, privacy and security are active topics of discussion from a wide range of perspectives. We will be bringing in these concerns for deliberation in this unit.

4.1 OBJECTIVES After going through this unit, you should be able to: •

appreciate the impact of information systems (IS) on society;

•

recognise the effect of the changes in Information Technology on moral dimensions and ethical issues;

•

appreciate the ethical principles and dilemma on account of information system;

•

discuss responsibility, accountability and liability in the use and application of information system, and

•

become familiar with information rights and intellectual property rights.

4.2 SOCIETY IN THE INFORMATION AGE The commercialisation of information communication technologies has been widely recognised as an important tool for economic growth. Strategies to utilise information technology for development priorities and prospects vary from sector to sector, and from country to country. 129

Information Management

Development Opportunities and the Information Age There is an established consensus that the information age offers significant potential for growth in all countries. The benefits of communications networks, principally reduced transaction costs and the ability to overcome impediments to productivity are especially important in considerations of how developing countries might more fully participate in the global economy. Despite the acknowledged potential of the information age for economic growth, most developing countries have yet to significantly benefit from the vast resources and opportunities made possible by information technology. There remains considerable uncertainty about the specific ways information technology can be applied to development goals and to promote identified objectives. Determining critical elements of a regulatory environment conducive for growth and development is particularly challenging, given the context- specific nature of the benefits of information technologies for productive economic and social activity. Importantly, the pervasive role of intellectual property rights in regulating almost all aspects of the digital economy has been insufficiently analysed as part of a broad development agenda for the digital economy. Patents, particularly pharmaceutical patents, have long been the subject of concern in and discussion of the role of intellectual property in development. This has occasioned neglect of other intellectual property rights such as copyright and trademarks. Yet, copyright law is essential to the viability of the Internet as a development tool. Virtually all aspects of the digital economy are affected by copyright or recent quasi-copyright systems that provide rights for technological protections of digital content. Copyrights, trademarks and patents each, and in some cases jointly, impact prospects for electronic commerce, access to computer software, the possibility of marketing cultural goods, the availability of educational content and much more. In short, intellectual property regulation permeates all aspects of the development opportunities occasioned by the commercialisation of information technology. Broad Applications of Information Technology Information technology has been applied to enhance four major categories of activities: governance, growth and supply / distribution of goods and services, adding value to existing services and the creation of new products and services. The range of activities that can benefit from information technology appears to be unlimited. Specifically however, the important issues for developing countries include how information technology can be used to overcome existing barriers in markets such as high transaction costs, inefficiencies in production, distribution and supply, while adding value to existing products and services and also creating new ones. Economists have noted that the failure of credit markets has been a major reason for underdevelopment. The prospects for secure electronic funds transfer may open up opportunities for financing entrepreneurial activity, which is important to stimulate local investment in information products. Investment in physical capital is critical to facilitate the use of new technologies in the production process. Investment in software is also particularly important. In OECD countries, software investments in the year 2000 accounted for over 50% of the investment in information technology. For local productivity to benefit from information technology, then, access to equity will be a vital component. Such access may be enhanced and facilitated by financial agreements through business to business (B2B) collaborations or other forms of financing by financial services available through the Internet.

130

Another key factor for growth is the quality of local labor. In this regard, the vast amount of educational resources available on the Internet is a critical resource for developing countries, as well as by linkages to institutions in developed countries. This extends beyond prospects for formal education. Specialised learning and ongoing informal education can take place through chat-rooms and other interactive forums enabled by the Internet. While the Internet cannot and should not replace structured educational systems, it is important to point out that the Internet has made it possible

to access recent and up to date information about any number of subjects, and to improve the quality of materials currently available in developing and least developed countries. These uses can also have a hortatory effect on the quality of life in developing countries by improving the quality of general participation in civil society and ultimately, democratic governance and delivery of government services.

Social, Ethical and Legal Aspects

Information technology can be used to address infrastructural barriers that have hindered traditional supply and distribution chains in developing countries. However, this benefit only goes to products or services that have no “real time/space” component. In reality, most e-commerce transactions still require physical infrastructure such as a dependable postal service, electricity, phone lines, etc., to function effectively. Only fully digital products are significantly insulated from the need for and dependence on the infrastructural capacity. With respect to developing countries then, it is important to identify how applications of information technology might contribute to economic growth, the particular sectors that would benefit particularly from information technology, and the legal rules that are most closely related to these sectors. Some Emerging Considerations i)

The Information Technology and Intellectual Property Interface

Despite indications of commitment from developed countries to support the integration of information technologies into development programs, most of the activities undertaken in the light of these commitments have failed to examine the important relationship between the regulation of information technology and global rules for intellectual property protection. As some scholars have argued, the information economy may require different rules with respect to the protection of content or even hardware, than the traditional economy. The contested boundaries between trademarks for domain names, business method patents for Internet businesses, and copyright protection for content all threaten precipitously to recreate high margins of difference between developed and developing countries. The irrepressible move to create a global property rights system in data and databases, both of which are the primary constitutive elements of the Internet and associated applications, together with the existing multilateral agreements create an unhealthy environment for development. In this “back to the future” paradigm, developing countries will be bound by international agreements that constrain their efforts to access the building blocks of economic growth which consist of access to content and competitive opportunities to create new markets and new products. It is important to note that this problem is not limited to developing countries; there continue to be conflicts and heated negotiations between stakeholders in developed countries about the nature and extent of rules designed for social and economic use of the information. ii)

Appropriating the Benefits of the Information Age

The Internet offers a dynamic set of technological tools, and is the subject of experimental regulatory frameworks and legal rules. It is unlikely that anything firm or consistently predictable will emerge any time soon to govern this digital space. For developing countries this presents both opportunities and challenges. Appropriating the benefits of the information age is directly related to how investments in information technology are influenced and supported by regulatory frameworks that promote innovation, access and use. In addition to capital investments in information technology, developing countries should undertake to invest in the necessary macroeconomic policies that will facilitate an environment where the domestic population is able to adapt to the existence of the Internet, and to encourage entrepreneurial uses of the different opportunities that information technology can offer to deal with existing distribution, dissemination and communication problems that bedevil developing country markets. 131

Information Management

132

Information asymmetries introduced or supported by legal rules such as intellectual property rights, or regulatory policies affecting competition in the provision of telecommunications services, can skew the competitive advantages that information technologies offer for developing countries. The following points summarize important factors that need to be kept in mind in formulating information policies with a development focus. 1)

Despite the emphasis on the need for a strong telecommunications infrastructure for greater physical access to the Internet, the development of third generation Internet technologies through satellite suggests that in a short period of time even this major problem may not be a significant barrier for access to the Internet. An important task, then, is to develop guidelines concerning how much developing country resources should be invested in adapting to the current Internet state of the art given the dynamic rate of innovation in communications technology. These are questions that require careful and sustained empirical analysis to ensure that in developing countries the digital divide does not remain a permanent feature of the information age.

Exploiting the potential of the Internet to facilitate development objectives requires access to hardware (computers), software and content. Innovation, competition and deregulation in the telecommunications industry will enhance the opportunities for access to hardware by citizens. Intellectual property agreements have important implications for access to software and digital content. In the context of software, developing countries need to explore alternatives to proprietary regimes, the most important being the Open Source model which has proven to be a dynamic and, in some instances, more effective model of software development. For developing countries the Open Source model is not just beneficial for improving access to software, but also for the opportunities it offers to facilitate the training of domestic software engineers, and the relatively low cost of complementary technologies.

Business method patents can have inhibiting effects on competition in new markets and the opportunities made possible by information technologies. Most economic analyses of business method patents suggest that such patents have an inimical effect on competition and organizational innovation. Developing countries should preserve domestic policy space to make decisions that are consistent with development priorities by adopting, as India has done, a per se rule against the patentability of business methods.

International copyright agreements have a significant and unavoidable impact on access to creative works in the digital age. The two WIPO Internet treaties have been implemented in a few developed countries in a manner that is highly restrictive and that imposes undue social costs on consumers. Developing countries should be aware that these two treaties affect access by wire and wireless means, and domestic limitations or exceptions to the rights granted by the treaties are likely to be influenced by interpretations of the TRIPS Agreement. Developing countries must insist on the possibility of enacting domestic limitations, including the application of compulsory licenses, to digital works.

The Appendix to the Berne Convention is currently the most prominent access model to literary works in international copyright law (Reference: www.unesco.org/culture/laws/copyright/images/copyrightconvention.rtf, The complete text of the Berne Convention and appendices can also be found at http://www.law.cornell.edu/treaties/berne/overview.html ) However, developing countries have not successfully utilized the provisions of the Appendix with regard to facilitating access to protected works through compulsory licenses. Consequently, an alternative model must be considered. Developing countries should consider, for example, adopting ad hoc provisions to deal with copyright

in digital works, rather than adopting wholesale treaty provisions that may deprive them of policy options more conducive to national priorities. What is ultimately important is that, in the context of multilateral or bilateral negotiations, developing countries must appreciate the importance of copyright to the ability to access and realize the benefits of information technology and information goods. Robust access principles in the international agreements, or the freedom to impose such access mechanisms domestically, must be preserved for development purposes. 6)

Social, Ethical and Legal Aspects

Institutions of higher learning are an important aspect of developing a strong technology base in any society. The possibility of distance education learning should occupy a central place in development strategies for the information age. This will require implementation of copyright treaties in a way that ensures that proprietary rights are balanced with public policy limitations that permit use and access for educational purposes, distinct from other socially beneficial uses.

4.3 MORAL DIMENSIONS There are five moral dimensions (a) information rights, (b) property rights, (c) accountability, liability, and control, (d) system quality, and (e) the quality of life. Let us examine these in details. a)

Information Rights

With respect to privacy and freedom in an Information Society there have been some attempts to regulate the collection and use of information about individuals, as explained in Table 1. Table 1: Principles of Fair Information Practices 1.

There should be no personal records system whose existence is secret.

Individuals have right to access, inspect, review and amendment to systems that contain information about them.

Without prior consent there must be no use of personal information for purposes other than those for which it was gathered.

Managers of systems are responsible and can be held accountable and liable for the damages done by systems for their reliability and security.

Governments have the right to intervene in the Information relationships among private parties.

Many of us take our privacy and freedom for granted. It needs to be noted how technology is changing and challenging our basic assumptions about these issues; for example, video rental records are more protected from misuse and prying than are your medical records. We all assume that the Constitution guarantees by us personal privacy and freedom from surveillance. If someone sets up a video camera inside your drawing room or on your front porch to monitor your every movement, what would you do? Such cases have happened, itâ&#x20AC;&#x2122;s a fact. So how do we protect our privacy and freedom from surveillance in a high-tech world? If ebay.com or rediff.com or Buy.com wants to collect information about your surfing habits and sell it to other companies, there is nothing to stop them. Absolutely nothing! However, in May 2006 with regard to Privacy for Phone Calls an Act has

been passed by Govt. of India (rajyasabha.nic.in/bills-ls-rs/2006/XLI_2006.pdf)). As per this Act no body can make unsolicited calls for commercial or other illegal benefits. Think about this: If information is supposedly collected for one purpose, is it ethical for that information to be used for a totally different purpose without your knowing it? Is it fair to require you to provide medical information that is primarily intended to be used to pay your insurance bills and then have that same information used against you when the insurance company deems you too expensive and cancels your policy? Is it fair to have that same information used against you in denying you employment because you’re too expensive to hire? Spamming (unsolicited emails) has been challenged in the courts by Internet Service Providers (ISP) as an unfair practice. The ISPs say the thousands of emails clog their systems and no one wants them anyway. The spammers argue that their right to Freedom of Speech is violated if they can’t send emails to anyone they want. Which side are you on? b)

Property Rights: Intellectual Property

Intellectual property issues have been around for hundreds of years. Some of the laws and policies in place to settle disputes about copyrights, patents, and trade secrets have to be rewritten to apply to the Internet. Intellectual property is a result of someone's effort to create a product of value based on their experiences, knowledge, and education. In short, intellectual property is brain power. What if you wrote the next great American novel, hoping to cash in big time? Maybe you could retire to the Bahamas and drink lemonade on the beach all day. But then you find out that someone posted your next great American novel to the Internet and everyone is reading it free of charge. Now you’re back in your hometown drinking lemonade at the local mall while you decide whether to look for a job at McDonald’s or Burger King. The good news is everyone loves your book! Unfortunately, that sort of thing happens too often in cyber-world. You’re pretty excited to get that free copy of the newest game software while the poor guy who spent hours of his time and effort writing it is not so excited to realise he’s not getting any compensation. Everything on the Web is considered to be protected under copyright and intellectual property laws unless the Web site specifically states that the content is public domain. The Web site doesn't need to carry the copyright symbol © in order for it to be protected. In the US, President Clinton signed a law in January 1998 making it a federal offense to violate copyright laws on the Internet, punishable with a fine up to $250,000. Copyright laws and intellectual property rights cannot be violated on the Internet any more than they can be violated in other mediums. While this isn’t a law class, you should be aware of the fine line between acceptable and legal usage of materials and the illegal theft of materials. When it comes to copyright material, the underlying ideas are not protected, just the publication of the material. On the other hand, a patent grants a monopoly on the underlying concepts and ideas. Before you use anything, especially any material on the World Wide Web, make sure you are using it legally and ethically. Get past the idea that because everything on the Web is free, easy, and available 24 hours a day, it must be okay to use it however you want. The question you should be asking yourself is “s it ethically right and legal?”

134

Accountability, Liability, and Control

Many of our laws and court decisions establishing precedents in the area of accountability, liability, and control were firmly in place long before computers were invented. Many of them date back to the early 1900s, and some simply don’t make sense in this day and age. That’s what we were referring to when we talked about new questions for organisations, companies, and the workplace in general. No issue makes this subject more important than the Internet laws our government has tried and still tries to pass. Government of India has enacted a comprehensive law in the form of IT Act 2000 (Ref http://www.legalserviceindia.com/cyber/cyber.htm).

Social, Ethical and Legal Aspects

However, in the US, the opinion of the Communications Decency Act (struck down by the courts) and the Child Online Protection Act (currently in the courts) is that Internet Service Providers should somehow be liable for content placed on the Internet through their users. Ask yourself these questions: If you receive an obscene phone call, is the telephone company responsible and liable for the problem? If you receive a threatening letter in the mail, is the Post Office authority responsible for reading every piece of mail on the chance that there might be a problem in one of the letters? d)

System Quality: Data Quality and System Errors

As we rely on Information Systems more, data quality issues are gaining importance. These issues affect you as a consumer and as a user. When the credit reporting agencies mess up your credit record and you can’t get a car loan, whose fault is it? Yours or of the credit agency? What if you’re driving down the road, the computer chip controlling your brake system fails, and you have a rather nasty crash? Who is at fault? You, the car company, or the company that made the computer chip? Most of us use software that the manufacturer knows has bugs. Once in a while these bugs will affect our computer usage. Usually they are nothing more than an aggravation. If you review Table 2 you’ll see some instances of data quality problems that can severely affect businesses and corporations. As more and more companies do business on the Internet, will Internet Service Providers be held accountable for equipment outages rendering those businesses unable to process transactions? Table 2: Examples of Reported Data Quality 1. An airline inadvertently corrupted its database of reservations while installing new software and for months planes took off with half load. 2. A manufacturer attempted to recognise its files by customer number only to discover the sales staff had been entering a new customer number for each sale because of special incentives for new accounts. One customer was entered 7000 times. The company scrapped the software project after spending $ 1 million. 3. A manufacturing company nearly scrapped a $12 million data warehouse project because of inconsistently defined product data. 4. J.P.Morgan, a New York bank, discovered that 40% of the data in its credit risk management was incomplete, necessitating double check by users. 5. Several studies have established that 5 to 12 % of bar code sales at retail grocery and merchandise chains are erroneous and that the ratio of overcharges to undercharges runs as high as 5.1 with 4.1 as a norm. The problem tends to be human error keeping shelf prices accurate and corporate policy that fails to allocate sufficient resources to price checking, auditing and development of error file policies.

Quality of Life: Equity, Access, Boundaries

Invariably, when discussing online technology, some people mention their concern about losing the face-to-face contact with other human beings. We hear stories about children who havenâ&#x20AC;&#x2122;t developed normal social skills because they spend all their time in front of a computer. No discussion about the quality of life issues would be complete without mentioning on-line love affairs. Of course, many people lose their jobs and their way of life because of technology. These are all valid concerns. One quality of life issue that affects more and more people personally is the ability to work from home. Most telecommuters used to have a regular day job 9 to 5, five days a week in a typical office setting. If they didnâ&#x20AC;&#x2122;t get their work done today, they would wait until they were back in the office tomorrow or Monday. Now because of technology they can work seven days a week, all hours of the day, at home. And sometimes they do. The impact on personal and family life can be considerable. There is an upside to the jobs issue, though. Many parents like telecommuting because they can stay home with, or at least be nearer, their children. More and more people are leaving the big cities and moving to small towns for the quality of life, yet they can still keep their well-paying jobs. Many small companies are able to expand their customer base because of technology, which in turns helps the employees immensely. Completely new businesses are born because of technology. Some people think weâ&#x20AC;&#x2122;ve reached the limit when they learn that we can now buy groceries online. After all, when you have everything loaded into the car, trying to find your way around a strange town, have three screaming kids in the back seat, and everyone is stressed out from the travel, the last thing you want to do is hunt down a grocery store. Why not email ahead and have your food and treats waiting for you when you check into your accommodations? What a terrific idea! Computer crime is one area that has been extremely hard for our society and our governments to keep up with. Many laws have to be rewritten and many new laws must be implemented to accommodate the changes. Computer crime and abuse extends to any wrongdoing involving equipment and Internet usage, as Table 3 shows. Anonymity cannot be a license for socially unacceptable behaviour. You should remember that everything you do on a network or the Internet is recorded and can be tracked. Many people committing computer crimes and abuse have been caught and prosecuted. Table 3: Internet Crime and Abuses Problem Hacking

Jamming Malicious Software Sniffing

Spoofing

136

Description Hackers exploit weaknesses in Web site security to obtain access to proprietary data such as customer information and password. They often use Trojan Horses posing as legitimate software to obtain information from the host computers. Jammers use software routines to tie up the computers hosting a Web site so that legitimate visitors cannot access the site. Cyber vandals use data flowing through the Internet to transmit computer viruses, which can disable computers they infect. Sniffing is a form of electronic eavesdropping by placing a piece of software to intercept information passing from a user to the computer hosting a Web site. This information can include credit card numbers and other confidential data. Spoofing is fraudulently misrepresents themselves as other organizations, setting up false Web sites where they can collect confidential information from unsuspecting visitors to the site.

Other issues affecting our society include job losses and career changes caused by technology. You can argue the positive or negative effects, but one thing is clear: you’ll be a part of the evolution of technology for the rest of your life. You will have to continually update your skills and knowledge in order to remain competitive in the job market. As companies continue to embrace new technology and new methods of using it, you’ll be responsible for ensuring your skills remain current.

Social, Ethical and Legal Aspects

Our government recognises the danger of allowing unequal access to technology to continue. It has enlisted the help of private individuals and corporations in an effort to install computers and Internet access in public schools and libraries across the nation. Most schools are now wired for networks and are learning to incorporate technology into the curriculum. Health Risks: RSI, CTS, and Technostress As managers, you should be acutely aware of the health issues caused by computer usage. Why? Because these health issues cost businesses huge amounts of money each year in medical treatment claims and lost productivity. Carpal tunnel syndrome (CTS) is the most serious health issue plaguing businesses. It doesn’t take much to avoid the problems associated with computer usage. Ergonomics, the study of the relationship between humans and machines, has helped determine that it’s cheaper to purchase equipment that reduces the health risks associated with computers such as different keyboards, monitors that reduce eye strain, and desks that allow proper body positions. Too much of a good thing can be bad. You’ve heard of road rage, the anger people experience when driving. We are now experiencing road rage on the Information Superhighway, where it is called techno-stress. Managers should encourage employees to take frequent breaks from their computer and to recognize and understand the dangers of isolation. We may be a wired nation, but we still need the human touch. How has all this technology affected you? Think about it. Ultimately, there is a positive and a negative side to everything. How you handle it determines how it affects you. Management Actions: A Corporate Code of Ethics. Many firms have not established a Code of Ethics or a policy for employee conduct when computing in today's workplace. Some corporations are confused about what to include and how to approach this new dilemma. It is felt that the five moral dimensions would be a good start. Businesses and their managers should recognise: •

The information rights to privacy and freedom

•

The property rights to individual ideas and efforts

•

The accountability, liability and control issues involved in using technology

•

The system quality requirements of businesses and individuals

•

The quality of life impact of technology

Companies can no longer ignore the necessity of establishing rules for technology usage. The issue will only continue to grow. If you work for a company that doesn’t have a policy, you should encourage it to establish one immediately. If you’re a manager in a company, you should get busy and establish a policy for your employees  it’s the only fair thing to do.

4.4 TECHNOLOGY TRENDS AND ETHICAL ISSUES New computer technologies for gathering, storing, manipulating, and communicating data are revolutionising the use and spread of information. Along the way, they are also creating ethical controversies. The speed and efficiency of electronic information systems, which include local and global networks, databases, and programs for processing information, force people to confront entirely new rights and responsibilities in their use of information and to reconsider standards of conduct shaped before the advent of computers. The Table 4 indicates the achievement due to technological progress of the Information System and their impact on the ethical issue. Table 4: Information System Achievements and Issues Achievement due to technological progress of Information System

Effect: can be found anywhere & uniquely identified

The Importance of Ethics in Information Systems Information is a source of power and, increasingly, the key to prosperity among those with access to it. Consequently, developments in information systems also involve social and political relationships ďŁ§ and so make ethical considerations in how information is used all the more important. Electronic systems now extend into all levels of government, into the workplace, and into private lives to such an extent that even people without access to these systems are affected in significant ways by them. New ethical and legal decisions are necessary to balance the needs and rights of everyone. Ethics Fill the Gap as Legal Decisions Lag Behind Technology As in other new technological arenas, legal decisions lag behind technical developments. Ethics fill the gap as people negotiate how use of electronic information should proceed. The following paragraphs define the broad ethical issues now being negotiated. Since laws deciding some aspects of these issues have been made, these paragraphs should be read in conjunction with Legal Issues in Electronic Information Systems. Ethical Issues Specific to Electronic Information Systems Ethics include moral choices made by individuals in relation to the rest of the community, standards of acceptable behaviour, and rules governing members of a profession. The broad issues relating to electronic information systems include control of and access to information, privacy and misuse of data, and international considerations. All of these extend to electronic networks, electronic databases, and, 138

more specifically, to geographic information systems. Specific problems within each of the three areas, however, require slightly different kinds of ethical decisions.

Social, Ethical and Legal Aspects

Computer Crimes Computer crime can be defined as an act of using a computer to commit an illegal act. The broad definition of computer crime can include the following: â&#x20AC;˘

Targeting a computer while committing an offense (e.g., gaining entry to a computer system in order to cause damage to the computer or the data it contains).

â&#x20AC;˘

Using a computer to commit an offense (e.g., stealing credit card numbers from a company database).

â&#x20AC;˘

Using computers to support criminal activity (e.g., drug dealer using computers to store records of illegal transactions).

Computer Crimes and the Impact on Organisations Dealing with viruses, PC theft and other computer-related crimes costs U.S. businesses a staggering $67.2 billion a year, according to the FBI report published in January 2006. The FBI calculated the price tag by extrapolating results from a survey of 2,066 organisations. The survey released found that 1,324 respondents, or 64 percent, suffered a financial loss from computer security incidents over a 12-month period. The average cost per company was more than $24,000, with the total cost reaching $32 million for those surveyed. Often survey results can be skewed, because poll respondents are more likely to answer when they have experienced a problem. So, when extrapolating the survey results to estimate the national cost, the FBI reduced the estimated number of affected organisations from 64 persent to a more conservative 20 percent. Under attack Almost a fifth of U.S. businesses said they suffered 20 or more incidents such as virus infections in an FBI survey of computer security incidents at companies in the past year.

20 or more: 19.2% 10-19: 9.1%

1-4: 51.5%

5-9: 20.1%

Figure 1: Loss by companies due to computer

This would be 2.8 million U.S. organisations experiencing at least one computer security incident, according to the 2005 FBI Computer Crime Survey. With each of these 2.8 million organisations incurring a $24,000 average loss, this would total $67.2 billion per year.

139

Information Management

By comparison, telecommunication fraud losses are about only $1 billion a year, according to the U.S. Secret Service. Also, the overall cost to Americans of identity fraud reached $52.6 billion in 2004, according to Javelin Strategy and Research. Other surveys have attempted to put a dollar amount on cyber security damages in the past, but the FBI believes its estimate is the most accurate because of the large number of respondents. AS per FBI the data set is three or four times larger than in past surveys. It is obviously a staggering number, but that is the reality of what is seen. Responding to worms, viruses and Trojan horses was most costly, followed by computer theft, financial fraud and network intrusion, according to the survey. Respondents spent nearly $12 million to deal with virus-type incidents, $3.2 million on theft, $2.8 million on financial fraud and $2.7 million on network intrusions. These figures do not include much of the staff, technology, time and software employed to prevent security incidents,. Also, losses to individuals who are victims of computer crime or victims in other countries are not included. Defenses in place As per FBI report survey respondents use a variety of security products for protection. Antivirus software is almost universally used, with 98.2 persent of respondents stating they use it. Firewalls follow in second place, with 90.7 persent, and anti-spyware and anti-spam are each used by about three-quarters of respondents. The results mean that close to one in 10 organisations does not have a hardware or software firewall. Or perhaps they don't know they have one ďŁ§ the Windows Firewall in Windows XP, for example. Some are very small businesses that should have that technology, but they donâ&#x20AC;&#x2122;t. Biometrics and smart cards--both relatively new security technologies--were used only by 4 percent and 7 percent of survey respondents respectively. Intrusion prevention or detection systems were used by 23 percent and VPNs, or virtual private networks, by 46 percent. Organisations were attacked despite use of security products, with nine out of 10 respondents saying they experienced a security incident. In fact, the most common attacks aligned with the most commonly used defenses. Computer viruses, worms or Trojan horses plagued 84 percent of respondents, 80 percent reported spyware trouble, and 32.9 percent said attackers were probing their systems using network port scans. Computer Crimes â&#x20AC;&#x201C; Who Commits Them? Not all threats came from outside the organisation. More than 44 percent of the FBI survey respondents reported intrusions from within the company. Companies may be unaware of the internal potential for computer security incidents. Unauthorised access Trend As per the data available the unauthorised data access is decreasing (see Figure 2) because of the growing awareness of the users who are using various protection techniques.

Computer Crime – Various Types Let us look at the various types of computer crimes as explained in Table 5. Table 5: Types of Computer Crimes Data Diddling

Salami Slicing

Phreaking

Cloning

Carding

The changing of data going into or out of a computer; for example, a student breaks into his/her university’s grade recording system and changes the grades he/she earned in last semester’s classes, thus raising his/her grade point average. A form of data diddling that occurs when a person shaves small amounts from financial accounts and deposits them in a personal account, for example a bank employee deposits a few Rupees from each of thousands of accounts into an account set up in a fictitious name. The amounts are too small to raise flags, but over time the thief collects a substantial sum. Crime committed against telephone company computers with the goal of making free long distance calls, impersonating directory assistance or other operator services, diverting calls to numbers of the perpetrator’s choice, or otherwise disrupting telephone service for subscribers. Cellular phone fraud in which scanners are used to steal the electronic serial numbers of cellular phones, which are used for billing purposes and are broadcast as calls are made. With stolen serial numbers, clones can be made to make free calls that are billed to the owner of the original cell phone. Refers to the practice of stealing credit card numbers online, to be resold or used to charge merchandise against victim’s account.

Piggybacking or shoulder surfing

Social Engineering

Dumpster diving

Spoofing

The act of simply standing in line behind a card user at an automated teller machine (ATM), looking over the person’s shoulder, and memorizing the card’s personal identification number (PIN). With the right equipment, the stolen numbers can then be placed on counterfeit access cards and used to withdraw cash from the victim’s account. Gaining information needed to access computers by means of tricking company employees by posing as a magazine journalist, telephone company employee, or forgetful coworker to order to persuade honest employee to reveal password and other information. The information is then used to break into a computer system or to steal company equipment and other contraband. This approach requires no technical expertise, since it consists simply of going through dumpsters and garbage cans for company documents, credit card receipts, and other papers containing information that might be useful. A scam used to steal password for legitimate accounts on computers in which the spoofer uses a program that duplicates an organisation’s login screen. When legitimate users login to the system, the counterfeit screen responds with an error message but secretly captures the user’s ID and password. The swindle lets intruders pass as legitimate users, thus allowing them to steal computer time and resources.

Computer Crimes  Hacking and Cracking Hackers is a term to describe unauthorised access to computers based entirely on a curiosity to learn as much as possible about computers. It was originally used to describe MIT students in the 1960s who gained access to mainframes. It was later used universally for gaining unauthorised access for any reason. Crackers is a term to describe those who break into computer systems with the intention of doing damage or committing crimes. This was created because of protests by true hackers. Computer Crime – Software Piracy Software Piracy is the practice of buying one copy and making multiple copies for personal and commercial use or for resale is illegal in most countries while others offer weak or nonexistent protections. This has become an international problem as shown in Table 6.

Destructive Codes that Replicate

142

Viruses are the programs which disrupt the normal function of a computer system though harmless pranks or by destroying files on the infected computer. They come in several types:

•

Boot Sector attaches to the section of a hard disk or floppy disk that boots a computer.

•

File Infector attach themselves to certain file types such as .doc, .exe, etc.

•

Combination viruses can change types between boot sector and file infector to fool antivirus programs

•

Attachment released from an e-mail when an attachment is launched. Can also send themselves to address book

Social, Ethical and Legal Aspects

Worms are the destructive codes which also replicate and spread through networked computers but do damage by clogging up memory to slow the computer versus destroying files Destructive Codes that do not Replicate Trojan Horses are the programs which do not replicate but can do damage as they run hidden programs on the infected computer that appears to be running normally (i.e., a game program that creates an account on the unsuspecting user’s computer for unauthorised access). Logic or Time Bombs are a variation of a Trojan horse that also do not replicate and are hidden but they are designed to lie in wait for a triggering operation. (i.e., a disgruntled employee who sets a program to go off after leaving the company). •

Time Bombs are set off by dates (e.g., a birthday)

•

Logic Bombs are set off by certain operations (e.g., a certain password).

Cyber war and Cyber terrorism Cyber war is an organised attempt by a country’s military to disrupt or destroy the information and communications systems of another country. Common targets include: •

Command and control systems

•

Intelligence collection and distribution systems

•

Information processing and distribution systems

•

Tactical communication systems

•

Troop and weapon positioning systems

•

Friend-or-Foe identification systems

•

Smart weapons systems.

Cyber terrorism is carried out through the use of computer and networking technologies against persons or property to intimidate or coerce governments, civilians, or any segment of society in order to attain political, religious, or ideological goals Responses to the Threat At greatest risk are those that depend highly on computers and networking infrastructure (i.e., governments, utilities, transportation providers, etc.) Responses include: •

Improved intelligence gathering techniques.

•

Improved cross-government cooperation.

•

Providing incentives for industry security investment. 143

4.5 ETHICAL PRINCIPLES AND DILEMMA In today’s information age, the social and ethical implications of information and communication technology (ICT) are enormous – and ICT is developing so rapidly that new possibilities emerge before the social consequences can be assimilated. New social / ethical policies for the information age, therefore, are urgently needed to fill rapidly multiplying “policy vacuums”. But filling such vacuums is a complex social process that will require active participation of individuals, organisations, and governments – and ultimately the world community. Globalisation has been given a practical shape by ICT developments and cyberspace has brought the word community closer for interaction and ICT has made possible – for the first time in history – a genuinely global conversation about ethics and human values. Such a conversation has implications for social policy that we can only begin to imagine. Traditional borders and barriers between countries have now become less meaningful because most countries are interconnected by the Internet. For this reason, individuals, companies and organisations in every culture can engage in global business transactions, distance education, cyber-employment, discussions of social and political issues, sharing and debating of values and perspectives. The points to be considered are; whether this “global conversation” will bring about better understanding between peoples and cultures? New-shared values and goals and new national and international laws and policies? Will individual cultures become “diluted,” homogenized, blurred? Issues: The worldwide nature of the Internet has already led to many issues which need of policies to resolve them. For example, if sexually explicit materials are provided on a web site in a culture in which they are permitted, and then they are accessed by someone in a different culture where such materials are outlawed as “obscene,” then, whose laws and values apply? Should the “offending” person in the first culture be extradited to the second culture and prosecuted as a purveyor of pornography? Should the values of the first culture be permitted to undermine those of the second culture via the Internet? Let us consider business transactions in cyberspace: Whose laws apply to business on the Internet? When people in one country purchase goods and services from merchants in another country, who should regulate or tax the transactions? And how will “cyber business” in a global market affect local business, local tax collections and local unemployment? What new laws, regulations, rules, practices should be adopted, and who should formulate them? What policies would be fair to all concerned? And how will global cyber business affect the gap between rich nations and poor nations? Will that gap get even worse? Will ICT lead to a “new colonialism” in which the information-rich lord it over the information poor? Will economic and political rivalries emerge to threaten peace and security? What kinds of conflicts and misunderstandings might arise, and how should they be handled? – and by whom? Or consider cyber medicine: medical advice and psychological counseling on the Internet, “keyhole” surgery conducted at a distance, medical tests and examinations over the net, “cyber prescriptions” for medicine written by doctors in one part of the world for patients in other parts of the world – these are just a few of the medical services and activities that already exist in cyberspace. How safe is cyber medicine? Who should regulate, license, control it?

144

Or consider education in cyberspace: hundreds of universities and colleges worldwide now offer educational credit for courses and modules. But when students earn university credits from all around the globe, who should set the standards? Who should award degrees and certify “graduates”? Will there be a “Cyber University of the World”? Will thousands of “ordinary” teachers be replaced by a handful of

“Internet-superstar teachers”? – or perhaps by teams of multimedia experts? – or even by educational software? Would such developments be wonderful new learning opportunities, or instead be educational disasters? What policies, rules, practices should be adopted and who should develop them?

Social, Ethical and Legal Aspects

At the social/political level of education, what will be the impact upon previously uneducated peoples of the world when they suddenly gain access to libraries, museums, newspapers, and other sources of knowledge? How will access to the world’s great newspapers affect “closed” societies with no free press? Are democracy and human rights necessary consequences of an educated population with access to a free press? Will the Internet foster global democracy? – or will it become a tool for control and manipulation of the masses by a handful of powerful governments? – or powerful corporations? Human Relationships: Of course, not all social/ethical issues which arise from ICT depend upon its global scope. Consider, for example, the impact of ICT on human relationships. How will family relationships or friendships be affected by mobile phones, palmtop and laptop computers, telecommuting to work and school, virtualreality conferencing, cyber-sex? Will the efficiency and convenience of ICT lead to shorter work hours and more “quality time” with the family? – or will ICT create instead a more hectic and breathless lifestyle which separates family and friends from each other? Will people be isolated in front of a computer hour after hour, or will they find new friendships and relationships in “virtual communities” in cyberspace – relationships based upon interactions that never could occur in regular space-time settings? How fulfilling and “genuine” can such relationships be, and will they crowd out better, more satisfying face-to-face relationships? What does all this mean for a person’s self-realization and satisfaction with life? What policies, laws, rules, practices should be put in place? Social Justice: As more and more of society’s activities and opportunities enter cyberspace – business opportunities, educational opportunities, medical services, employment, leisure-time activities, and on and on – it will become harder and harder for ICT “have-nots” to share in the benefits and opportunities of society. Persons without an “electronic identity” may have no socially recognised identity at all! Therefore social justice (not to mention economic prosperity) requires that society develop policies and practices to more fully include people who, in the past, have had limited access to ICT resources: women, the poor, the old, rural residents, persons with disabilities, even technophobes. A good example is “assistive technology” for persons with disabilities. A variety of hardware and software has been developed in recent years to enable persons with disabilities to use ICT easily and effectively. As a result, people who would otherwise be utterly dependent upon others for almost everything suddenly find their lives transformed into happy, productive, “near-normal” ones. Visual impairments and blindness, hearing impairments and deafness, inability to control one’s limbs, even near-total paralysis need no longer be major impediments to happiness and productivity. Given such dramatic benefits of assistive technology, as well as rapidly decreasing costs, does a just society have an ethical obligation to provide assistive technology to its citizens with disabilities? Work: Work and the workplace are being dramatically transformed by ICT. More flexibility and choices are possible (e.g., tele-working at home, on the road, at any hour or location). In addition, new kinds of jobs and job opportunities are being created (e.g., webmasters, data miners, cyber-counselors, and so on). But such benefits and opportunities are accompanied by risks and problems, like unemployment of computer-replaced humans, “deskilling” of workers who only push buttons, stress keeping up with high speed machines, repetitive motion injuries, magnetism and radiation from computer hardware, surveillance of workers by monitoring software, and ICT “sweat shops” that pay “slave wages.” A wide range of new laws, regulations,

Information Management

rules and practices are needed if society is to manage these workplace developments efficiently and justly. Government and Democracy: ICT has the potential to significantly change the relationship between individual citizens and governments – local, regional and national. Electronic voting and referenda, as well as e-mailed messages to legislators and ministers, could give citizens more opportunities to make timely input into government decisions and law making. Optimists point out that ICT, appropriately used, can enable better citizen participation in democratic processes, make government more open and accountable and provide easy citizen access to government information, reports, services, plans and proposed legislation. Pessimists, on the other hand, worry that government officials who are regularly bombarded with e-mail from angry voters might be easily swayed by short-term swings in public mood, that hackers could disrupt or corrupt electronic election processes, that dictatorial governments might find ways to use ICT to control and intimidate the population more effectively than ever before. What policies should be put in place to take account of these hopes and worries? Intellectual Property and Ownership: In the information age, the “information rich” will run the world, and the “information poor” will be poor indeed! Possession and control of information will be the keys to wealth, power and success. Those who own and control the information infrastructure will be amongst the wealthiest and most powerful of all. And those who own digitized intellectual property – software, databases, music, video, literary works, and educational resources – will possess major economic assets. But digitized information is easily copied and altered, easily transferred across borders, and therefore the piracy of intellectual property will be a major social problem. Even today, for example, in some countries over ninety percent of the software is pirated – not to mention the music and video resources! What new laws, regulations, rules, international agreements and practices would be fair and just, and who should formulate or enforce them? It is also possible to mix and combine several types of digitized resources to create “multimedia” works of various kinds. A single program, for example, might make use of bits and snippets of photographs, video clips, sound bites, graphic art, newsprint and excerpts from various literary works. How large must a component of such a work be before the user must pay copyright royalties? Must the creator of a multimedia work identify thousands of copyright holders and pay thousands of copyright fees in order to be allowed to create and disseminate his/her work? What should the rules be and who should enforce them? How can they be enforced at all on the new frontiers of cyberspace?

4.6 RESPONSIBILITY, ACCOUNTABILITY AND LIABILITY In the Information Systems discipline, increasing attention is being paid to the issues of professional ethics. Ethical choices are decisions made by individuals who are responsible for the consequences of their actions. Key elements include:

146

•

Responsibility: An individual accepting the potential costs, duties, and obligations for decisions they make. May require social norms and laws to enable.

•

Accountability: Mechanisms in social institutions to determine who is responsible and assessing responsibilities for decisions and actions.

•

Liability: Political means to permit individuals to recover damages via due process. Due process insures laws are applied properly and laws are known and understood, with an ability to appeal to higher authorities.

Responsibility by software users expected by the software developersâ&#x20AC;&#x2122; is primarily the protection, or violation of that protection, of software programs. Issues relating to the copying of software programs and protection by copyright laws are discussed in detail in unit 4.8. Software users or consumers on the other hand may claim that they have the right to use a product for which they have paid, and indeed have the right to expect Responsibility by the software vendors that that product will be free of defects (bugs). This imposes a duty of quality (and professionalism) on the developers of the software to ensure that the software is indeed bug-free. Consumers expect that a product be competitively priced, providing value for money.

Social, Ethical and Legal Aspects

Professional accountability is an issue that is closely tied to many codes of ethical conduct. As per ethical code of conduct it is expected that members shall accept professional responsibility for their work and for the work of their subordinates and associates under their direction, and shall not terminate any assignment except for good reason and on reasonable notice. Members are expected to be accountable for the quality, timeliness and use of resources in the work for which he/she is responsible. In general, accountability lies at the root of vendor-client relationships, and is therefore relevant to both the professionals (from developers as well as from users side). Accountability is important because it shows that high-quality work is valued, encourages professionals to be diligent and responsible in their practice, and establishes just foundations for Liabilities and/or compensation when software does not perform according to expectations, or when professional advice turns out to be unreliable. Accountability is also important because computer software is used throughout our society, and is an essential component of many life-critical systems, such as transportation equipment (aircraft, trains, lifts), medical devices, toys, accounting and financial control systems (ATMs), weapons systems, communications devices (radar, telephones, televisions, satellites, networks), and domestic appliances (microwave ovens, TVs, refrigerators, air-conditioning systems). Through encouraging a strong sense of professional accountability, we can attempt to ensure that those who are responsible for the safe functioning of these systems will do their utmost to ensure that systems are safe, and will minimize risks. Accountability runs a considerable risk of being eroded, however, when computers are made scapegoats for human failings or when developers of computer software deny any responsibility for the consequences of use of the software, even when this use is in accordance with the purpose for which the software was designed. Let us look at a scenario relating to accountability dilemma of this type. A computerized investment system was designed for and purchased by a pension fund management company. The user of the system became familiar with it, and requested IT staff (not the original designer) to make some modifications to the system. Shortly afterwards, substantial losses were incurred and payments to pensioners had to be cut. Who is accountable? The original system designer? The user who requested modifications? It is perhaps all too easy to blame the computer, apologize, and do nothing. Accountability is generally assumed to include a number of components, viz.: responsibility (direct or indirect) and liability. Liability relates to who should pay compensation (financial redress, community service,â&#x20AC;Ś) as a result of being held responsible for an action. In some situations, liability may apply, i.e., requiring the payment of compensation to a victim even though the harm has not arisen through one's deliberate or direct actions. For example take an aircraft systems, if an aircraft crashes due to a system failure, then the airline is subject to liability even though the airline has not deliberately or directly caused the crash. Such cases of liability help to ensure that extraordinary care is taken over the development and maintenance of systems that have the potential to cause loss of life. Although the definition of accountability is fairly straightforward, four barriers to accountability can be identified: the problem of too many hands; the computer as scapegoat; the problem of bugs; and ownership without liability. Computer software is especially vulnerable to the problem of too many hands, because most (if not all)

147

Information Management

software is necessarily designed and developed by a number of individuals, often at different points in time. Furthermore, software often has a symbiotic relationship with computer hardware. This makes it very difficult to identify precisely which person should take responsibility for any unexpected action. However, such complexity can be no defense and there is a clear need to attempt to identify who should take responsibility for the problem. If we do not attempt to apportion blame, not only will the responsible person(s) escape blame, but they may cause further problems to happen in the future. The net result is that accountability is eroded, with no one prepared to step forwards and take responsibility. Information systems are often blamed for human errors because they intermediate communications between people. If a human action is mediated by a computer, there is a strong tendency to blame the computer rather than the human (designer, programmer or user) that caused the computer to produce incorrect information. With the increased use of computers, computers will be made scapegoats for human failings with increasing frequency. In this situation, it is vital to establish lines of responsibility because it is all too easy for humans to shirk their responsibilities. Bugs include all types of software errors, including those made at the design, modeling and coding stages of system design. Bugs certainly make software unreliable and can cause system failure, with the potential for loss of life or severe damages. There has been an unfortunate tendency for bugs to be seen as an inevitable aspect of computer systems, even as natural hazards that computer users have come to accept. This view is not restricted to the software developers, with prominent commentators on IT ethics voicing similar views, asserting “It is the nature of software programs to have errors…”. However, the very purpose of professional accountability is that we should identify who has caused a harm- whether intentionally or through negligence. If we accept that bugs are inevitable, then accountability becomes impossible - we can merely regret that harm was caused, but defend ourselves by saying that bugs are unavoidable (even expected) and therefore no one should be held responsible for the harm. There may even be resistance to liability  if no one can be identified as accountable, then why should anyone pay compensation - which is precisely why the concept of liability is so important. If, however, we do not view bugs as natural hazards, but as manifestations of unprofessional and sloppy work, we should be able to identify lines of responsibility, particularly for persistent bugs. Furthermore, if we are to act as true professionals, we cannot be satisfied with the notion that bugs are inevitable -it is like saying that the loss of human life through human error is inevitable, and that when we turn on a TV set, there is a reasonable chance that it will short circuit and electrocute us. Society has the right to expect that domestic appliances, and many other essential systems, will function safely. As we have mentioned previously, the legal aspects of software product reliability are complex. Nevertheless, in order to understand the relationship between bugs and liability, it is instructive to introduce the legal rights and duties of developers and customers. Strict liability is generally applied by courts when a person or property is injured or damaged. Thus, purely economic damages are usually not put to Strict Liability. A second category of liability is known as negligence. Developers can avoid accusations of negligence by ensuring that they take reasonable care in the design, coding and testing of their products. One problem here relates to the thoroughness of testing. If a company has followed industry standards with regard to testing, then it would appear that if bugs still exist, it cannot be accused of including such bugs either deliberately or through carelessness. Whilst this does not obviate the requirement for software to be bug-free, it certainly does imply that industry standards may need to be set at very high levels. A third liability category is known as breach of warranty. A warranty is essentially a promise that the developer makes to the customer with regard to the functionality of the software, and forms “part of the contractual agreement between the seller and the buyer.

148

Having identified these categories of liability, it is important to note that pre-packaged software (Microsoft Word, Netscape Navigator, etc.) are generally recognised to be products, but custom-developed applications are considered to be services. This distinction is critical since while the standards of liability are applicable to products, they are not to services. Individually customized software must therefore be legally covered by the specific contract that is agreed upon between the developer and the customer, where penalties for non-functionality, lateness of delivery, etc. may be specified.

Social, Ethical and Legal Aspects

Computer software developers affirm that they sell a user the licence to install and use (typically) a single copy of a software package; they are not selling the ownership of the software. However, at the same time, software developers employ disclaimers to minimise as far as possible any liability (e.g., for financial or data losses) arising out of the customer's use of the software. Indeed, we note an unfortunate tendency for software producers to deny to the maximum extent possible any responsibility for actions caused by their software. Same time, consumers are held to be liable for any use of the software that lies outside the narrowly-worded terms of the software license agreement. This situation has the effect of eroding the rights of the user, since virtually all the risks of using the software (but few of the rights) are transferred to the user. Legally, these disclaimers have been recognised in courts so long as they are explicit and prominently displayed. There is evidence to indicate that the tendency to disclaim liability is growing more serious, noting that many software companies intend to implement measures that would have the effect of further diminishing consumers' rights. Another consequence of minimizing liability is the software developers’ parallel denial of responsibility for any bugs that they may include (intentionally or inadvertently) in the software. Essentially, when you buy software, you install and use it as is, i.e., at your own risk. We argue, however, that such transfer of risk is unreasonable because it imposes upon the developer no duty to ensure that software is bug-free, nor even - so long as these bugs do not cause loss of life or injury - to provide bug-fixes when they are identified. This seems to be both unethical and unprofessional  consumers have the right to use a product that fulfils the agreement with the vendor  explicitly or implicitly. At the same time, developers have a moral duty to ensure that the software they sell is usable and “fulfils the explicit and implicit contract between the buyer and seller. We maintain that if software developers wish to retain their ownership rights, then they should be both responsible and liable for their products, since they are in the best position (owning source code) to have direct control over the quality of their software. We suggest that accountability and liability to compensate need to be separate. An individual programmer or software designer may be responsible for harm, but liability more properly lies with the employer, since it retains responsibility/ownership for the work of its employees. There is a strong need to clarify and promote standards of care in system design that are acceptable to users and developers alike  perhaps via a code of practice. Furthermore, the practice of extensive disclaims needs to be reviewed. Customers have the right to be informed if there are known bugs, irrespective of whether the developer intends to fix them, and irrespective of whether the developer thinks they are significant or not. Not informing the customer amounts to misrepresentation. Indeed, misrepresentation can be a form of contract violation and so may potentially attract legal penalties of a different kind. With respect to bugs, appropriate standards of testing need to be promulgated and adhered to, while excellent documentation of "who does what" should enable lines of accountability to be established. Independent software auditors may be called upon to verify software quality, if possible applying ISO standards. Accountability is clearly vital not only for the information systems profession, but also for us as professionals, if we are to be held in the highest regard by those for whom we develop systems.

4.8 INTELLECTUAL PROPERTY AND RIGHTS The copying of software programs, although nominally protected by copyright laws, is certainly widespread. While some may acknowledge that such copying is tantamount to theft, the activity persists if only because it is so easy, the chance of getting caught 153

Information Management

is considered negligible, and the software developers are perceived as being rich enough already. Such copying is not restricted to personal users – businesses are involved as well, though often inadvertently. It is not uncommon to notice that employees contribute significantly to the presence of illegal software in the workplace, posing serious financial and legal consequences for their employers. Among those [companies] surveyed, software decision-makers indicate that colleagues bringing software from home (40%), downloading unauthorized copies from the Internet (24%), and sharing programs with other employees (24%) are three of the most common forms of violation occurring in their companies. The philosophical basis for software protection lies in the prima facie right to private property, particularly property that can be said to be the ‘fruit of one's endeavors’. These views are not accepted by all nations with the same gravity. In Chinese society, for instance, the “socialization process emphasizes obligations and duties that promote conformity, collective solidarity, and obedience while downplaying assertiveness and creativity”. The similarity between a “preoccupation with social order” in Chinese society and a “preoccupation with individual freedom” in Western societies is a point to be noted. These fundamental cultural and social differences certainly raise difficulties in legislative attempts to provide for universal protection of creativity. A danger inherent in copyright protection is that when a technology is wholly owned by a single entity (individual, organisation), consumers may be harmed because the opportunity for competition is much diminished. Monopolies can lead to reduced evolution and diffusion of products, as well as overpricing and underproduction. Given these opposing forces, there clearly needs to be a reasonable balance between protection of a product on the one hand, and the right of consumers to avail themselves of the product at reasonable cost on the other. Indeed, in Korea and Japan there is a public assumption that new ideas and technologies should be shared in the public domain so that members of a society can benefit. In many developing countries, meanwhile, governments are, quite naturally, more concerned that new technology should spread through all of a society as rapidly as possible, enabling the country to leapfrog older generations of technology and catch up with the rest of the world. The notion that technology should in some way be strongly protected, with profits going overseas, is not one that they feel is good for the development of the local economy. In such contexts, much of the argument about INTELLECTUAL PROPERTY AND RIGHTS (IPR) lies in the principles between rights and duties. Software producers claim that they have the right to protect the fruit of their endeavors  the software programs. Furthermore, they have the right to be compensated for the resources that they have expended in the development of that product. This right is translated into a right to charge consumers what they deem a fair price for the software products  a price that covers the various developmental costs, as well as generating profits that can be used for future product research and development. To protect their right to the protect fruit of their endeavors, they claim that consumers have a duty both to pay the price and to respect the intellectual property contained within the product  by not stealing it.

154

The notion of ownership of something, whether it has a physical form or not, does still make sense as intellectual property. There are a number of laws and agreements throughout the world to protect intellectual property rights. The right to copy or duplicate materials can be granted only by the owners of the information. This is called the copyright. Many documents on the Internet contain a statement that asserts that the document is copyrighted and gives permission for distributing the document in an electronic form, provided it isn't sold or made part of some commercial venture. Even items that don't contain these statements are protected by the copyright laws of the United States, the Universal Copyright Convention, or the Berne Union. Most of the copyright conventions or statutes include a provision so that individuals may make copies of portions of a document for short-term use. If information is obtainable on the Internet, and there is no charge to access the information, it can often be shared in an

electronic form. That certainly doesn’t mean you can copy images or documents and make them available on the Internet, or make copies and share them in a printed form with others. Quite naturally, many of the folks who create or work at providing material available on the Internet expect to get credit and be paid for their work.

Social, Ethical and Legal Aspects

Copyrights Challenge by Electronic Information Systems :The fluidity of information on the networks has caused some confusion about how copyrights and intellectual property rights apply to electronic files. In the relatively small world of the original network users, an emphasis on free exchange of information and a common understanding of intellectual property allayed most potential conflicts over use of information. Now, as the networks grow larger and attract a broader range of people, some clarification of how electronic files may be used is becoming necessary. The ease with which electronic files can be distributed and the nature of some electronic information create problems within existing copyright law: either the law does not address the peculiarities of electronic information or the law is too easily subverted by the ease with which files can be copied and transferred. Similar problems have arisen with photocopy machines, VCRs, and tape recorders. To make matters more complex, other countries may have different copyright laws, so information made available globally through a network may not have the same protection in other places. The basic existing copyright principles should keep most network users on ethical grounds.

•

Copyrights protect original works of authorship, including literary, musical, dramatic, graphic, audiovisual, and architectural works, and sound recordings.

•

The law forbids unauthorised reproduction, distribution, performance, or display of works with copyrights. The general intent of the law is to protect the commercial value of a work.

•

Having a copy of a work with a copyright does not mean that the holder also has the right to distribute, reproduce, perform, or display it.

•

Copyrights apply to both published and unpublished work. Under the international Berne Convention on copyrights, which the U.S. signed in 1989, a copyright comes into effect from the moment a work is created and is fixed in some form of tangible expression.

•

A copyright notice is not required for copyright protection. The only way a copyright can be invalidated is by explicit announcement by the author that copyright protections are waived.

•

Copyrights do not apply to titles, short phrases, names, slogans, mere listing of ingredients, or works consisting entirely of unoriginal information (such as standard calendars).

•

Copyrights do not extend to ideas, procedures, methods, systems, concepts, principles, discoveries, or devices; these must be patented for protection.

•

Remember, Complete international copyright protection does not exist. Works are subject to the laws of individual nations, although most nations have signed international agreements on copyrights.

Law for Work Created on a Network: The principles of copyright laws apply easily to work not created in an electronic file. But what about original work that is created within a network? The law applies in sometimes surprising ways, and users should think about copyrights before distributing or reproducing work created by another person. For instance: E-mail.

155

Information Management

E-mail is protected by copyright. Information received in e-mail may be discussed, but the specific contents of e-mail have copyright protection. Usenet postings may also be protected. These may be read and discussed by however, many people have access to the Usenet, but they cannot be reproduced and distributed in any way that may diminish the author's ability to profit from the original work ďŁ§ however farfetched such profit may seem. There is an interesting question concerning network postings, does the fact that anything you say in an on-line system can be downloaded and printed out by anyone who happens to read it create a different class of reproduction than quoting without permission from a commercial publication? If a journalist quotes something from an on-line system and does not obtain permission, did s/he steal it, or overhear it in a conversation? In such cases it can be concluded that whatever seems like fair use probably is, but that actual control of such use is impossible and that good manners are critically important. Computer programs, which might appear to be ideas, procedures, systems, or devices, may be registered as literary works under the law, and therefore, receive copyright protection.
