Discussion Questions 1. Brainstorm a list of discretionary information that might be an output of an accounting information system and be needed by Starbucks. Prioritize which items might be most important and provide support. Answers will vary. Here are some potential answers: The cost of a cup of coffee, by type: Breakfast blend, Cafe estima, caffe Verona, espresso roast, Ethiopia sidamo, French roast, Gold Coast blend, Guatemala Antigua, house blend, Italian roast, Kenya coffee, komodo dragon blend, organic Serena blend, organic shade grown Mexico, Sumatra, decaf caffe Verona, decaf espresso roast, decaf house blend, and decaf Sumatra!

Monthly Sales per square foot of retail space. Employee cost for each operating hour. Advertising expenditures per dollar of sales. The cost of condiments per dollar sales of coffee. Condiments might include sweeteners, liquid creamers, cream canisters, sugar packets, sugar canisters, stir sticks! The cost of electricity per operating hour each month of the year. 2. Explain the information value chain. How do business events turn into data then into information and then into knowledge? Give an example starting with the business event of the purchase of a Super Smash Bros. Nintendo Switch Game at GameStop all the way to giving useful information for the CEO and other decision makers. The information value chain represents the overall transformation from a business need and business event (like each individual sale of U.S. flag) to an ultimate decision. The information

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

value chain might be represented considering the purchase of a Nintendo Switch Game at Best Buy in the following way: The game will be recorded as sales revenue and then after deducting its costs will add to or subtract from corporate income. The cash from the game sale will also add to the operating cash flows. The specific game will be recorded in the information as a sale to monitor which games are selling within Best Buy. This will help Best Buy and its suppliers know which games are selling and which type of games should be reordered. The type of game will also help the marketing department better understand its customers and their respective demographic profile to better market to them. In addition, knowing the location of the game sale will also help decision makers know where its sales are occurring. The CEO can look at the profitability of games overall, the specific types of games that are selling and the location of those sales all due to the information value chain. 3. Give three examples of types of discretionary information at your college or university and explain how the benefits of receiving that information outweigh the costs. Answers will vary. The following represents potential answers: Universities are often interested in their freshmen retention (the percentage of sophomores that return after their freshman year). They also quite interested in their four- or five-year graduation rates. Universities are also interested in their production of research grants. This is often used to monitor the success of their research and their ability to get interested sponsors (such as the National Institute of Health or the National Science Foundation). Information for each of these three examples can be gained by the information system at the university. However, a university generic information system does not usually offer this information as a standard report or standard output of the system. Therefore, work must be done to capture (and potentially digitize) this information, ensure its validity and then report it in an appropriate useful format. The cost of getting useful information will depend on the university and its technology. However, since these represent three keys metrics of a university and will likely be used as a key input to manage the university, the benefits will potentially outweigh those costs. 4. After a NCAA women’s basketball game, a box score is produced detailing the number of points scored, assists made and rebounds retrieved (among other statistics). Using the characteristics of useful information discussed at the beginning of the chapter, please explain how this box score meets (or does not meet) the characteristics of useful information. A box score of a NCAA women’s basketball game (or other sports) produces overall team statistics by half and quarter and details player performance including minutes played, shots taken, shots made, free throw shots taken and made, assists, rebounds, steals, blocks and fouls. To be relevant, the information must potentially impact a decision that a decision maker must make. Relevant information is usually characterized by having predictive value, feedback value

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

and receiving it on a timely basis. This information provides feedback value to explain how players performed in the game. The box score provides predictive value to the extent that prior performance (as reflected in the box score) is predictive of future performance. Since box scores are available immediately following the game, it is also received on a timely enough basis to make decisions for a subsequent game. To exhibit the quality of faithful representation, the information must be verifiable, be representationally faithful and be neutral. There are often some allegations that the statistics included in a box score is affected by the bias of the scorekeeper. While the actual points scored by the team is verified by the officials, more minute details are not verified and may be subject to bias, thus limiting their reliability. The information is potentially relevant to the coach in helping to figure out which players are most efficient and productive. Which players play well against different teams and which players are good at particular aspects of offense and defense, among others. 5. Some would argue that the role of accounting is simply as an information provider. Will a computer ultimately completely take over the job of the accountant? As part of your explanation, explain how the role of accountants in information systems continues to evolve. Accountants have a role as a business analyst. That is, they gather information to solve business problems or address business opportunities. They determine what information is relevant in solving business problems, then create or extract that information and finally analyze the information to solve the problem. An AIS provides a systematic means for accountants to get needed information and solve a problem. While a computer is very good at reliably collecting, processing and producing information, the role of the accountant when serving as a business analyst will continue to be able to assess the problems the business is facing and work to provide information that will address it. 6. How do you become a Certified Internal Auditor (CIA)? What do they do on a daily basis? An individual can earn a CIA designation with a combination of required education, professional experience, character references and passing of the CIA exam. The CIA designation identifies accountants with a broad range of knowledge about the company. They work inside an individual company, generally providing an independent assessment of the company’s operations, including the effectiveness of a company’s internal controls. They may be called upon to investigate the possibility of fraud in financial statement reporting, or investigate the throughput of a manufacturing system, among many other things. On a daily basis, CIAs might evaluate internal controls associated with financial reporting, help devise a more efficient financial reporting system, or help audit an operational issue which the audit committee needs to better understand. 7. How do you become a Certified Information Technology Professional (CITP)? What do they do on a daily basis?

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

A CPA can earn a CITP designation with a combination of business experience, lifelong learning and an optional exam. The CITP designation identifies accountants (CPAs) with a broad range of technology knowledge and experience. On a daily basis, CITPs may help devise a more efficient financial reporting system, help figure out how an information system can provide needed decision-relevant information, help the accounting function go paperless or consult on how an IT function may transform the business. 8. Explain the value chain for an appliance manufacturer, particularly the primary activities. Which activities are most crucial for value creation (or in other words, which activities would you want to make sure are the most effective)? Rank the five value-chain enhancing activities in importance for an appliance manufacturer. The value chain goes all the way from product design, through sourcing to manufacturing to shipping the final product to the warranty and repair business. Many would consider the product design, which ensures that the appliance has the desired functionality at the right priced points, to be a critical activity for value creation. Sourcing the product components to low cost, yet high quality component providers is also key to creating value. Final assembly (or operations) of the product components is also key to ensuring high product quality at reasonable prices. Marketing the final product through appropriate distribution channels and supporting the final product through the warranty and repair process also are crucial parts of the value chain. My opinion of the ranking of the five primary activities would be that product design would be the most important, then sourcing (inbound logistics), then marketing, then warranty and repair and finally final assembly (or operations). 9.

Which value chain supporting activities would most be most important to support a healthcare provider’s primary activities? How about the most important primary activities for a university? Of course, all of the supporting activities are important. Human Resources perhaps can be viewed as most important to make sure the right nurses and right doctors with the appropriate skills are available at the right time to service the sick and injured. Technology is increasingly becoming an important part of hospitals, especially with the digital medical records are becoming increasingly available and useful. Certainly, other arguments can be made for other supporting activities. The primary activities of a university would be to attract students, educate them and then helping them find a good job once they have graduated. Educating students is probably the most important primary activities in the university as that is its primary mission. 10. Where does new product development fit in the value chain for a pharmaceutical company? Where does new product development for a car manufacturer fit in the value chain? The support activity of technology generally would include research and development for both a pharmaceutical company as well as a car manufacturer. In either case, this is a support activity that can drive the value for a company.

11. List and explain three ways that an AIS can add value to the firm. Accounting Information Systems add value by providing decision relevant information to management. Three specific examples would include the following: Customer relationship management (CRM) techniques could attract new customers, generating additional sales revenue. Enterprise systems can significantly lower the cost of support processes included. Supply Chain Management Software allows firms to carry the right inventory and have it in the right place at the right time. 12. An enterprise system is a centralized database that collects and distributes information throughout the firm. What type of financial information would be useful for both the marketing and manufacturing operations might both need? Both marketing and manufacturing operations might both need records of the past sales as well as projections of which products are selling best. For the marketing group, this information would be helpful to optimize marketing campaigns, understand the demographics of the customer, and make predictions of future products. Manufacturing operations might need product information to decide which products to produce as well as needed changes to be able to produce future products. The enterprise systems might be able to provide answers to questions like, what manufacturing equipment might be needed to produce new products or is the existing manufacturing capacity sufficient to fulfill future product needs. 13. Customer Relationship Management software is used to manage and nurture a firm’s interactions with its current and potential clients. What information would Airbus want to know about its current and potential airplane customers? Why is this so critical? For Airbus, understanding its customers is of paramount importance. Airbus would want to know who their potential customers are, who the key contacts are, what the customer’s business models are (e.g., short flights, long flights, fuel efficiency, loads on each flight, cargo volume and capacity, etc., who their key supplier has been in the past (Boeing, Airbus, Embraer, Comac, etc.) , what they value in a plane manufacturer (e.g., financing, customer service, after sale service, parts, etc.). This information is critical as it helps Airbus tailor its offering and propose new offerings based on the needs of the customer. 14. What data from internal business processes will serve as inputs into a cost accounting system for your university? From which specific enterprise systems will this data be recorded and managed? Data from internal business processes would be 1) direct and indirect labor (professors, lecturers, administrative assistants, recruiters, etc.), 2) use of buildings, computer equipment, furnishings (depreciation, maintenance, repair), 3) security (police, fire, security guards), etc. This data generally comes from financial reporting systems and human resource management systems.

15. How would an AIS help a company identify the products with the highest profit margin? Accounting information systems keep track of the revenues and the costs of each product. If the information is reliable, exhibiting the faithful representation qualities, AIS can compute the highest profit margin and highest profit margin percentages. This will help the company know how best to grow its profits, potentially by increasing sales of the products with highest profit margins and perhaps deemphasizing those of lowest profit margin.

Problems (Note – Problems with “Connect” in parentheses below are available for assignment within Connect.) 1. Accenture recently wrote an article entitled, “Meet the Finance 2020 Workforce” (2017) suggesting that accountants will need to not only embrace traditional financial questions of "What happened" and "Why did it happen" questions, but also the questions of "What should we do"? How is that consistent with the idea that the accountant should serve as a business analyst argued in the chapter? Accountants address management questions, and serve as business analysts. They not only measure what happened and why it happened, but they also help address the questions of what should happen next based on expectations. They help management address these questions and optimize a company’s prospects for the future. This is increasingly the role of accountants in the modern business organization. 2. Accenture recently wrote an article entitled, “Meet the Finance 2020 Workforce” (2017) suggesting that accountants will need to embrace new financial roles to analyze new business opportunities and way the organization can profit from them. Consider the internal and external business processes and give ideas of how they might allow the accountant to analyze business opportunities and how the company might able to profit from them. Financial Reporting Systems – Accountants record and manage the financial reporting system, capturing financial transactions, and summarizing and communicating their results to all interested stakeholders. While this is a traditional role for accountants, increasingly they are being called on to gather insights from firm performance and use such information to set and evaluate company strategy. Will offering new products or entering new markets actually be profitable for the company? Human Resource Management Resource System - Since company employees are generally regarded as the company's most important asset, such a system helps a company manage and evaluate its labor force. Such information from the system might help an accountant see if they have the needed capacity to meet customer needs. Accountants can help determine if the company will have the necessary human capital capability to address strategic opportunities the company may face. Supply Chain Management System – Accountants help determine if they have the right product in the right place at the right time at the right price, or, in other words, refers to a network of processes that delivers a finished good or service to the final customer. Accountants might

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

address questions like: Is there a cheaper way to source the product? How much inventory should we hold to not run out of product while maintaining a lean organization? Customer Relationship Management System – The customer relationship management system might help the company determine customer preferences and ordering patterns. Accountants might help determine the optimal mix of products to offer and the optimal price for each product. 3. If computers and enterprise systems do much of the traditional work of recording transactions and processing journal entries and other accounting information, what role is left for the accountant to perform? Answers may vary. With computers doing much of the recording and processing of accounting information, the accountant can become more of a business analyst, knowing what information is available and knowing what information is needed to help management make important decisions. 4.

6. In 2002, John Deere’s $4 billion commercial and consumer equipment division implemented supply chain management software and reduced its inventory by $500 million. As sales continued to grow, they have been able to keep their inventory growth flat. How did the supply chain management software implementation allow them to reduce inventory on hand? How did this allow them to save money? Which income statement accounts (e.g., revenue, cost of goods sold, SG&A expenses, interest expense, etc.) would this affect? The use of supply chain software allowed the business to reduce its inventory and then as sales growth continued, keep its inventory growth flat. This is at least $500 million less that the company had to finance with either liabilities or equity. To the extent it reduced its debt, this would reduce its interest expense. The reduction in inventory also reduced the number of needed warehouses to store the inventory, potentially reducing SG&A expenses. (Connect only) Questions Supply chain software allows a business to reduce which of the following balance sheet accounts? If the reduction in inventory reduces the need for warehouses for storing product, which income statement accounts would this affect? A reduction in inventory frees up cash to reduce longterm debt, which income statement account would this affect?

Answers Inventory Sales, general and administrative expenses Interest expense

7. Dell Computer used Customer Relationship Management Software called IdeaStorm to collect customer feedback. This customer feedback led the company to build select consumer notebooks and desktops pre-installed with the Linux platform. Dell also decided to continue offering Windows 10 as a pre-installed operating system option in response to customer requests. Where does this fit in the value chain? How will this help Dell create value? By listening to the customer and meeting their needs, will this increase revenues or decreases expenses? The use of IdeaStorm at Dell helped Dell get to know its customers and their needs. The primary activity in the value chain that directly addresses the use of CRM is marketing and sales activities, which identifies the needs and wants of their customers to help attract them to the firm’s products and buy them. Using customer feedback to get to know their customers helps Dell get the right product at the right price to the right customer. It will potentially increase revenues and potentially reduce obsolete inventory by having the products that the customers need. (Connect only)

Please take each of these results and explain which of these systems most directly affected those results. 1. Decreased direct product costs by 11% - this likely came about by efficiencies gained by the supply chain system. 2. Increased labor productivity by 16% - this likely came about by efficiencies gained by the supply chain system. 3. Increased inventory turns by four times - this likely came about by efficiencies gained by a combination of the supply chain system and customer relationship management (by having the right product to the right customer) 4. Decreased order processing time by 90% and decreased implementation time by 40% (this was likely caused by a combination of the implementation of supply chain management, customer relationship management and enterprise systems). 5. Ensured minimal business disruption - uncertain how this is tied to the implementation of supply chain management, customer relationship management and enterprise systems 6.

Answer: D Discussion Questions 1. How might an airline use data analytics to evaluate different services provided to business and casual travelers to maximize revenue? Data Analytics might be used in an airline setting to maximize revenue of selling to business and casual travelers in many ways. For example, data analytics might define business travelers by the time before travel that a ticket is purchased (say in the final week before travel is made) and define casual travelers also by the time before travel (say before the final week before travel is made). Data Analytics could then look at questions like baggage charges and giving one rate for those who purchase baggage more than a week ahead of time versus those who purchase baggage less than a week ahead of time. 2. What is the difference between Big Data and data analytics? Give an example of the difference. Big Data is defined as datasets that are too large and complex for businesses’ existing systems to handle utilizing their traditional capabilities to capture, store, manage, and analyze these datasets while Data Analytics is the science of examining raw data (now often Big Data), removing excess noise from the dataset, and organizing the data with the purpose of drawing conclusions for decision making. Big Data seems to highlight the size of the data, that it is simply so big and unmanageable, but Data Analytics uses context to figure out what is needed to draw conclusions to be useful in decision making. Specifically, Data Analytics provides a way to search through large and unstructured data to identify unknown patterns or relationships. As an example, Big Data might collect all tweets since the beginning of Twitter to answer questions. Data Analysis might take that data, extract the appropriate information to answer a question and then address questions like:  What do tweeters think about Christmas?  How do investors (those that are on Twitter) respond to a share buyback?  Do tweeters retweet earnings announcement information to others? Accountants may incorporate data analytics into their work by using it to assess estimates, predict goodwill write-downs, predict audit issues and outcomes, and as a basis for managerial decision making. 3. Why is it important to have software vendors, such as ACL Inc., use the Audit Data Standards? For software that companies and/or audit firms consistently use (like SAP), it would be very helpful to have an option to output information in conformance with Audit Data Standards. That would make it a relatively effortless exercise to export or import data from an external party. If the software vendors know these standards well in advance, they can make it much easier for their customers and be a highly value-added option to the software the vendors provide. 4. What efficiencies are there for external auditors to use Audit Data Standards? Before an audit, external auditors ask the company being audited for certain information. In the past, they have generally been flexible as to how the data is extracted and formatted for their use. The external auditors then have to spend time doing Extract, Transform and Load to get it ready for analysis and testing. 3

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

If both the company being audited and the external auditor are able to communicate electronically using Audit Data Standards (ADS), then the transfer of information will be relatively effortless and error free. The time that was used to extract and reformat the data can now be used for the arguably more important testing and analysis performed by external auditors. 5. In field 17 of Exhibit 2.6, Audit Data Standards includes a record of who approved the journal entry. Why do you think the external auditor might be interested in this field? Why do you think they might also be interested in who modified a journal entry (field 19 of Exhibit 2.6) and on what date (field 20 of Exhibit 2.6)? External auditors perform tests of controls to analyze segregation of duties and other internal controls. For this reason, the Audit Data Standards maintains a field that tells not only who entered a journal entry (Field #14 in Figure 1), but who authorized that journal entry (Field #17 in Figure 1). Understanding who modified a journal and the date of such modification might help one understand who has the ability to modify a journal entry to make sure it is consistent with established internal controls. 6. What is the difference between descriptive and diagnostic analytics? Descriptive analytics is usually more factual, stating what happened that doesn’t require a lot of extra analysis. A sum of assets, a count of customers, or a histogram of aged accounts receivable would be typical of descriptive analytics. In contrast, diagnostic analytics requires more detailed analysis to figure out what happened. For example, while descriptive analytics would figure out we earned more profit this year, diagnostic analytics would figure out why that occurred – was it more revenue or less expense, were we more profitable in some regions than in others? Were customers responding to higher quality or better advertising, etc.? 7. What type of analytics (descriptive, diagnostics, predictive, or prescriptive) is required to find the needed product sales to break even? Why? Prescriptive analytics would be required to find the needed level of product sales required to breakeven. Prescriptive analytics is defined as identifies best possible options given constraints or changing conditions. Prescriptive analytics would allow us to change the performance on earlier sales and see how it might impact the needed score on the final exam to achieve a particular grade.

10. (LO 3-6) If the CEO prefers less detail in their written report, the analyst might suggest a. an executive summary. b. a complete set of visualizations. c. a full report. d. a sampling of the most important visualizations e. None of the above Answer: A Discussion Questions 1. Answers will vary. Tableau and Power BI are substantially easier for some visualizations. They connect with more kinds of datasets and handle more data. They are designed for data analytics and Excel requires pivot tables first. 2. Students should recognize the substantial similarities and consider the elements listed in the Data Visualization Concepts section as well as the Common Elements section. To prepare a quality report, a student would need to understand the audience, the data, and the questions to be addressed, gather data, organize the data, and present it in the best way to communicate the information to the intended audience. 3. The Common Elements section provides a good start to a list of required capabilities. Various data analytics software products can be compared based on what data they connect with, the ease of setting relationships among tables, the ability to select and/or create attributes, and the ability to present the data in a variety of easy to use charts/visualizations. 4. Answers will vary. Both products are very capable. 5. Most students will say they use pie, bar, and line charts. This can lead to a discussion of why they chose those charts, what the advantages are, and whether there are any disadvantages. 6. Increasingly, visualizations are preferred to written content to communicate results. For example, 91 percent of people prefer visual content over written content.1 Why is that? Well, some argue that the brain processes images 60,000 times faster than text (and 90 percent of information transmitted to the brain is visual). However, sometimes it is hard to see precise numbers in a visual, so that so that would be one case where a table of numbers might be superior to a data visualization. 7. Explanatory visualizations, as opposed to exploratory visualizations, specifically communicate results of the data analysis to interested stakeholders. Since they have different audiences (analysts vs. decision makers), they will have different aims. Problems

1. (LO 3-2, LO 3-4, LO 3-5) Match the data visualization to the type of data analytics (descriptive, diagnostic, predictive, or prescriptive) it is most associated with.

Discussion Questions 1. The answers will vary according to the student’s background, but it is likely that they will feel best prepared to use technology and less prepared to design, manage, and evaluate technology. 2. Managing regulatory compliance would involve collection and maintenance of a wide variety of information. First, organizations would have to collect regulatory requirement information. Then, they would have to collect process information to identify where process activities must comply with regulations. Finally, they would have ongoing collection of process performance data to ensure continued compliance and reporting. 3. The answer to this question depends on the individual but most students should be forming foundational and intermediate skills by the time they graduate. 4. The answer to this question depends on the individual but most students should be forming basic and applied knowledge by the time they graduate. 5. The IMA Competency Framework was a specific section titled Technology & Analytics so at first glance, students are more likely to say the IMA framework emphasizes technology more. However, technology and analytical skills are implicit in many of the topics. 6. If students search for the word: processes in the IMA Competency Framework document, they will find it on almost every page. This is a good opportunity to discuss the importance of processes and process documentation to accounting and business functions. 7. The CGMA Competency Framework foundational skills require basic understanding of business structure, operations and financial performance. Almost every skill could be facilitated by business models, so this is an opportunity to select a skill and discuss how or why models could aid the development of that skill. 8. Student responses will vary depending on their experience, but most will mention training, SOX compliance, regulatory compliance, identifying and collecting process performance information, aiding audits, and so on. 9. BPMN diagrams serve similar purposes to flowcharts. The following table compares basic symbols and shows the similarities. The BPMN symbols have more capability to handle events and the Gateways are more flexible that the flowchart decision symbol. The extended list of symbols in the chapter shows that many flowchart symbols are closely tied to specific and outdated data processing methods, whereas the BPMN symbols are independent of the technology.

Comparing BPMN to data flow diagrams shows that the models are very different. Data flow diagrams do not have start, end, or intermediate event symbols. They do, however, clearly show the flow of data in a process or processes, where the BPMN diagram more clearly shows the sequence of activities. 10. The stewardship and reporting function relates to regulatory/tax compliance. Accountants would need to collect information on regulatory regimes, tax rates, laws and regulations imposed and the performance of the company to comply with those laws and regulations. 11. BPMN activity diagrams support process documentation, process evaluation, and process improvement. Thus, BPMN diagrams would document the finance and accounting processes to support employee training. An accurate documentation would support an evaluation of process inefficiencies and potential process improvements including applications of technology, as well as a review of internal controls over the process and identification of potential weaknesses. 12. Process modeling is iterative. The analyst will model the process and then confirm his/her model with process participants. The confirmation process would likely raise questions about completeness. 13. The use of pools and lanes help establish responsibility. It would be hard to enforce responsibility where multiple departments are involved. Additionally, the assignment process helps define tasks/activities at an appropriate level of detail that allows the models to be used for training, process change, performance management, etc. 14. Exclusive gateways show distinct choices, such as when you select one option among multiple alternatives. Inclusive gateways allow selection of one or more options, such as ordering both an entrée and an appetizer or just an entrée. Parallel gateways take all possible options, such as when dining at a restaurant that charges one price for the meal that includes an appetizer, main course, beverage, and dessert. 6

15. When the process experiences a delay such as described, the best way to model that is through the use of an intermediate event, such as an intermediate message (catching) event. 16. Processes that start with a timer event could be time to prepare financial reports, time to pay taxes, time to attend class, etc. 17. The basic steps are to establish the purpose of the business process model, describe the context, outline the basic process steps, define the activities comprising each step, refine the diagram and decompose activities, validate the model with stakeholders.

Answers to discussion questions 1. Although the foreign key could be posted in either table, it makes sense to post it in the cash receipt table. The multiplicities indicate that the cash receipt instance occurs after the corresponding sales instance. If you post the foreign key in the sale table, the field would be blank and then when entering cash receipt information, the database would need to update two tables (to update the foreign key in the sales table). If the foreign key (the sales primary key) is posted in the cash receipt table, that value is always available when the cash receipt information is added. 2. The multiplicities suggest the business sells items on account and collects payment in full. Each payment is for one sale. The multiplicities would change to 0..* next to the cash receipt class, indicating a minimum of 0 and a maximum of many payments for each sale. 3. Each student may take a minimum of 0 and a maximum of many courses. Each course may have been taken by a minimum of 0 and a maximum of many students. The tables would look something like: Students [Student ID (PK), Student Name, Student Address, Student email, …] Courses [Course number (PK), Course Name, Course Description, …] Student-Courses [Student ID + Course Number (PK), Date Student Took Course, Grade Student Earned, …] 4. The composition relationship would look like the model below. The descriptiveness is a matter of taste.

5. Other examples of composition relationships include a person and the parts of the anatomy, a sale and the related sales items. Composition relationships are a form of aggregation relationships where the parts do not usually exist separately. Examples of aggregation relationships include a bouquet and the individual flowers, a university and individual colleges, a high-rise building and the floors, etc. 6. There were undoubtedly a number of rules in the process: the student must pay tuition before enrollment; the student must have taken prerequisite courses before enrolling; the student must be admitted to the University before enrolling; the student cannot enroll outside of a specific date range. Most if not all these administrative rules would be expressed in writing so that they could be implemented in the University systems.

7. A typical checkout would show the items selected for purchase (in your cart), shipping costs, taxes, the customer’s name, address, phone number, and email for both billing and shipping, plus payment information (e.g., credit card or PayPal). Decision categories might include Calculation (what are the shipping costs for example); Fraud (is the credit card stolen); Targeting (what other products should we suggest to this customer). There would be rules about which fields had to be completed. There would be rules about valid forms of payment. There could be rules about valid shipping destinations. 8. There are some obvious differences between the association lines and the relationship diamonds in the two figures. The ERD names the relationship, providing additional information about the business purpose of the relationship. Less obvious is that the multiplicities/cardinalities are on the opposite side.

9. A simple class diagram for attending several universities is as follows:

(This assumes that Universities have at least one student and a student has attended at least one University.) If the diagram is drawn from the University’s perspective, the answer would depend on the purpose of the information. In the most likely case that the purpose is to collect students’ education history, then the answer would be the same. 10.10. a) Examples of one-to-one relationships include: Cash sales at the supermarket (one cash receipt per sale) Sales of new cars (each sale includes one car and a new car is sold only once) Credit card sales over the internet (one sale and one cash receipt)

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

b) Examples of one-to-many relationships include: Sale of a new car and the customer’s payments Customers and sales Employees and paychecks Houses and the cities they are located in (excluding mobile homes) c) Examples of many-to-many relationships include: Sales and inventory (at a grocery store) Payments over time on credit card sales (each payment may apply to several sales and each sale could result in several payments) Answers to Problems 1. Dr. Franklin runs a small medical clinic specializing in family practice. The following simple diagram describes the basic relationships. It incorporates several assumptions: 1) a patient visit (sale) could take place without any diagnostic tests; 2) the tests/services are established in the database before they are used by Dr. Franklin; 3) patients are established in the database prior to the first patient visit (sale). Extensions to this model could include adding a second payer, such as an insurance company, as well as several options for payments (which are not shown in the diagram below).

2. Paige ran a small frozen yogurt shop. She bought several flavors of frozen yogurt mix from her yogurt supplier. She bought plastic cups in several sizes from another supplier. She bought cones from a third supplier. She counts yogurt and cones as inventory, but she treats the cups as operating expense and doesn’t track any cup inventory. The simple diagram below describes Paige’s purchases. Normally, a purchase must involve at least one inventory item, but she expenses the cups upon purchase, so a cup purchase involves 0 inventory items whereas a yogurt or cone purchase involves at least one inventory item. This model also assumes that suppliers are recorded before items are purchased from them.

3. A table structure to support problem 1 would look like: Patients Sales/Visits Tests/Services Visits-Services

[Patient ID (PK), Patient Name, Patient Address, …] [Patient Visit Number (PK), Date, Basic Fee, Other Charges, Total Amount Due, Patient ID (FK), ..] [Test/Service ID (PK), Test/Service Description, Charge for this Test/Service, …] [Patient Visit Number + Test/Service ID (PK)]

Books and DVDs are associated with Check Out Books/DVDs, Computers are associated with Computer Use Sessions, Rooms are associated with Room Reservations Next to Patrons, the multiplicities are all 1..1; next to the event/transaction classes (Issue Library Cards, Check Out Books/DVDs, Computer Use Sessions, Room Reservations), the multiplicities are 0..*. Each transaction involves a minimum of 1 and maximum of 1 Patron; Patrons can participate in a minimum of 0 and maximum of many transactions. Each Check Out Books/DVDs transaction can involve a minimum of 1 and maximum of many Books and DVDs; each Book or DVD can be checked out a minimum of 0 and maximum of many times. Each Computer can be used in a Computer Use Session a minimum of 0 and maximum of many times; each Computer Use Session involves one computer (minimum of 1 and maximum of 1). Each room can be reserved a minimum of 0 and maximum of many times; each Room Reservation is for one Room (minimum of 1 and maximum of 1). The following model shows the Multnomah County Library data model. Each county citizen may obtain a library card, so the association between Patrons and Issue Library Cards indicates that constraint. Patrons can check out multiple books or DVDs. Patrons can use one computer at any time and reserve rooms. This assumes that each room reservation involves one room.

Discussion Questions 1. Explain the differences between hierarchical, network and relational data models. What makes the relational data model the most popular data model in use today? Hierarchical data models organize data into a tree-like structure. In a hierarchical data model, data elements are related to each other using one-to-many relationships. A network data model is a flexible model representing objects and their relationships. It allows many-to-many relationships. The relational data model is a data model that stores information in the form of related two-dimensional tables. While hierarchical and network data models require relationships to be formed at the database creation, relational data models can be made up as needed. The relational database is the most popular data model in use today because it has the following advantages: flexibility and scalability simplicity reduced information redundancy. 2. What are the basic requirements of a relational database? The approach of relational database imposes requirements on the structure of tables:

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

     

The Entity Integrity Rule: the primary key of a table must have data values (cannot be null). The Referential Integrity Rule: the data value for a foreign key must either be null or match one of the data values that already exist in the corresponding table. Each attribute in a table must have a unique name. Values of a specific attribute must be of the same type. Each attribute (column) of a record (row) must be single-valued. This requirement forces us to create a relationship table for each many-to-many relationship. All other non-key attributes in a table must describe a characteristic of the class (table) identified by the primary key.

3. Structured Query Language (SQL) is used to retrieve data from a database. Why would an accountant need to learn SQL? The information accountants needed is not always ready for use in the database. Accountants need to use SQL to pull data needed out from the master table, to design queries to get the calculated data and to run report in an application. Additionally, learning SQL helps accountants better communicate with IT support when they need assistance. 4. Exhibit 6.56 lists the modules available from SAP. List and explain which modules would be most appropriate for either Maytag or a manufacturing company you are familiar with. —MM Materials Management: for the manufacturing companies, material management such as raw material purchase and usage, storage and condition check is always important because it affects the manufacturing process and cost of goods. —PP Production Planning and Control: Production Planning consists of all master data, system configuration, and transactions to complete the Plan in produce process. It related to the planning stage to the completion of manufacturing, it is critical to the whole process of manufacturing. —SD Sales and Distribution: The Sales and Distribution consists of all master data, system configuration, and transactions to complete the Order to Cash process. It is the purpose of manufacturing. 5. Given the description of Hershey’s failed enterprise system implementation from the chapter, which of the four challenges of the enterprise described in the chapter seem to best explain what happened? Use Google or Yahoo! to get more details on this case to help answer this question.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

The challenge of integrating with the firm’s own existing legacy systems best described Hershey’s failure of implementing of ERP. Before 1999, Hershey was running legacy systems. When it tried to implement ERP system in 1999, it chose to replace those systems. But the changes cause the delayed delivery of goods during holiday season and big loss in that year.

Problems 10 to 14 Ellen Novotny started an online bookstore in 2023. You are Ellen’s best friend and promised to help her. Ellen asked you to create a small database to track the information on books and authors. You created the following tables: Author, Book, and Author_Book.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

The table, Author_Book, is a relationship table to link the Author table and Book table because of the many-to-many relationship between the two tables. That is, each author may write many books and each book may have multiple authors. In general, each customer can purchase many books in a single transaction. Also, copies of the same book can be sold to different customers. Once an order is processed, the books are shipped right away. Based on these tables you have (see below), help Ellen to extract the information she needs from the database. 10. Ellen asks you to give her a list of the books that each author wrote. Write a complete SQL statement to provide the information to Ellen, including author names, book titles, publishers and the years of publication. Author Table Author ID AU-1 AU-2 AU-3 AU-4 AU-5 AU-6

Answers to Discussion Questions 1. Managers are concerned about many aspects of the sales and collection process. In particular, they likely would collect product/inventory information about sales trends, customer information about product preferences and cumulative sales activity, employee information about sales productivity per employee or location, as well as sales by month, quarter, and year. 2. The standard example of businesses that collect cash before recording sales are magazines, but there are also many others. For example, airlines sell tickets before customers travel. Regardless of when the cash is collected, the class model remains basically the same. However, internal controls (and the business rules that implement internal controls) could change. The focus no longer is on the collection from the customer, but rather on the delivery of goods or services according to the agreed contract. 3. A simple BPMN model for a fast food restaurant:

A similar model for a traditional restaurant (a more complex model could also include initial activities of seating the customer, taking beverage order, etc.):

A model that incorporates reservations (could also use a generic intermediate event to show the wait until the time of reservation):

4. A collaboration diagram would show two pools: customer and restaurant, and the message flows between them. For a traditional restaurant (as shown above), the order of the message flows would change and the customers would pay after receiving their food.

5. There is no difference between the UML class diagrams for fast food versus traditional restaurants. In both cases, there is a one-to-one relationship between the sales event and the corresponding cash receipt. The difference in payment timing is so minor that it would not normally be shown. To add reservations to the model, you could add a commitment (reservations) event that precedes the sales event. Note that both these models include the customer class, but most restaurants do not track specific customers.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

In the model with reservations, each reservation is related to a minimum of 0 and a maximum of 1 sale; each sale is related to a maximum of one reservation but some sales take place without prior reservations.

6. Collaboration sales model for Amazon (note that there could be a loop involving the first 4 activities until the customer decides to checkout, plus the delivery is most likely a sub-process, since it would be much more complicated than the other activities in the process):

In a traditional brick and mortar store, there are no formal search, report, and select activities. The customer presents items and checks out. So, the traditional model would be much simpler.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

7. Business rules for the sales process could include 1) payment must be made, 2) acceptable payment options, 3) handling of large bills (e.g., Starbucks employees place $20 bills and larger immediately in their safe), plus 4) a variety of practices to prevent theft – both by customers and employees. 8. The classes and associations below would be used in accounts receivable queries. For a balanceforward calculation, the query would simply sum sales and collections since the previous statement balance; for an open-invoice calculation, the query would list the specific sales and the corresponding receipts for each of those sales.

Answers to Problems Problem 7-1: Beach Dude a. UML Class Diagram shown below:

The minimum multiplicities between BD Products and Clothing Line are set to 0 by default, since it can be assumed that product items and clothing lines are defined before the links are defined. The minimum multiplicities between Employees and Customers are set to 0 since some employees may not work with customers, and some customers may not have an assigned salesperson, yet. The student may make alternate assumptions but should document those assumptions. Connect Solution a.1 Diagram Location A. B.

Since each sale is related to only one cash receipt, the sale and cash receipt events are collapsed into one in this solution. While they might also be modeled as separate Sale and Cash Receipt events with a 1:1 relationship, there are no attributes in the list for a Cash Receipt event in this case. This model shows separate inventory, programs, and packages classes, but it would be easy to combine those 3 classes into one class with some modification to the attributes.

Chapter 7 Comprehensive Exercise - BAER BELLY BIKINIS’ SALES TO RETAILERS – Solution (Connect Only) 1. Develop the BPMN diagram for BBB’s sales process. a. The purpose of the model is to describe BBB’s current sales process in preparation for business expansion. b. Context diagram.

c. Basic process flows.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

The basic steps in the process are record order, produce products, ship products, and collect payments. The produce products can be modeled as a collapsed subprocess since it is more complicated than a single task. The basic process flow is allocated to lanes within the BBB pool to reflect the different departments involved in the sales process.

d. Student responses will vary with exceptions, errors, etc. 2. Prepare a UML Class Diagram of BBB’s sales process. There are two primary agents: Retailer Customers and BBB Employees (you could also consider the Sales Representatives as agents). There are two events: Retailer Orders/Sales and Cash Receipts. There are two resources: BBB Finished Goods Inventory and Cash. There are two type images: Fabric Colors and Inventory Types. There are two associations between Employees (Emp) and Retailer Orders/Sales indicating employee roles.

Answer: D Solutions to discussion questions 1. Business rules for Place Order, Receive Items, Assess Items, Place in Inventory, and Pay Supplier process steps are clearly segregation of duties rules. These rules are generally prohibited rules, since they describe what cannot take place in terms of separation of duties. The Place Order rule “Manager approval required for orders > $5,000” is a mandatory rule. 2. Wal-Mart’s vendor managed inventory affects their purchases and payments process by delaying purchase until the product is delivered to the store. This means in many cases that the products will be sold before Wal-Mart has to pay their vendor. In terms of process design, it means that Wal-Mart probably tracks inventory in the distribution center before it is purchased. Thus, there must be some receiving event that precedes the purchase event. 3. Here is one possible model of the textbook purchase process:

4. Exhibit 8.5 shows a business that issues purchase orders and then receives goods. This would apply many types of organizations, including retailers, government entities, wholesalers, etc. Businesses might use alternate models if they use a credit card and pick up their items when purchasing. Other businesses may purchase directly from vendors without purchase orders, such as the local convenience store getting deliveries from the Coca-Cola distributor. 5. Other possible type images for Exhibit 8.7 include a Purchase Types class to help define different types of purchases, an Employee Type image to assure that trained buyers are doing the purchasing. 6. The use of contracts would change the basic purchase activity flow in Exhibit 8.2 and 8.3. The first step would then be the contracting process itself, which could be modeled as a sub-process. Other steps would remain the same. The UML class diagram would then include another commitment event to document the contracts, and then the Purchase Order event would link to the Contracts event. For example, the BPMN could look like this. Alternately, there could be a task to check whether a contract exists. If yes, then branch directly to Place Purchase Order. If no, then branch to Contract for Items.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

The basic UML diagram would add a contract event as follows. This diagram assumes that each product is possibly related to multiple contracts and each contract is related to multiple products.

7. When two processes are integrated, such as the sales and purchase process, the resources and internal agents are typically shared across processes. Inventory is both purchased and sold. Employees participate in both sales and purchases. The external agent and the events are relevant to one process only. Customers only participate in Sales events, and Suppliers only participate in Purchases events. 8. An accounts payable query would include the Suppliers agent (to whom the amounts are payable) and purchases and cash disbursements event. The logic is: for each supplier, sum the 8

purchases. For each supplier, sum the cash disbursements. For each supplier, calculate the difference between the sum of purchases and the sum of cash disbursements. Solutions to problems 1. Tablet Store Purchases a. UML Class Diagram

Answers to Discussion Questions 1. There are several reasons that accountants should be concerned with the development of bills of material. Students should refer to Exhibit 4.1 in Chapter 4 that shows the roles of the accounting/finance function in business. In particular, the student should note the business management support roles, such as planning, budgeting and forecasting, cost management, and supply chain management. Additionally, in the performance measurement and management role, accountants need to understand the content of bills of material so they can prepare appropriate variance reports for management. 2. There are many types of businesses that use conversion processes to convert raw material into finished goods. For example, restaurants, car repair services, pharmaceutical companies, computer manufacturers, automobile manufacturers, wineries, breweries, gasoline refineries, etc., use variations of the conversion process. While all use raw material, labor, and overhead in the conversion process, there are some differences in information structure as well as the sequence of activities. Some processes follow a series of steps in which both labor and raw material are used; other processes introduce all the raw materials in the beginning and then apply labor after the raw material is available. Of course, organizations that use activity-based costing have somewhat different information structures than organizations using more basic allocation schemes. 3. The purchases and payments process would link to the conversion process through the raw material resource, since purchases increase the quantity of raw material on hand. The conversion process would link to the sales and cash receipts process through the finished goods inventory resource, since the conversion process increases and the sales process decreases finished goods quantities on hand. All three processes also share internal agents, employees. The following UML diagram provides a simple example (without multiplicities). The resources, cash, raw materials inventory, finished goods inventory, are shared across processes. The Employees agent is related to every event, so it is also shared across processes. The two events and external agents are unique to processes, so the Suppliers agent and the Cash Disbursement and Purchase events are specific to the purchases process. The Raw Material Issue, Production

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

Authorization, and Labor Operations events are specific to the conversion process. The Sales and Cash Receipts events and the Customer agent are specific to the sales process.

4. Indirect labor is part of overhead costs typically assigned in terms of either direct labor hours or direct labor dollars. The actual indirect labor costs would be recorded through the payroll process. 5. To implement activity-based costing, the organization needs to record usage of the cost driver for each activity. Thus, Exhibit 9.8 would have to include 3 additional events to record that information. 6. The integrated model, simplified, is shown below:

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

7. Answers will vary. For example, the first rule for the Authorize Production step is obligatory; the other rules are prohibited. The first rule could be restated as a prohibited rule: A nonsupervisory partner must not authorize production > $5,000. 8. Comparing exhibits 9.7 and 7.20, one similarity is that both include resources, events, and agents. However, exhibit 9.7 has no external agent and no event affecting cash. The duality is between the authorization event and the related events recording material issue and labor operations. The main reason is that the conversion process describes changes in internal resources, raw material and finished goods (products) inventories, and the allocations of associated costs, but it does not show interactions with external parties.

Discussion Questions 1. How has the Sarbanes-Oxley Act affected the audit profession and corporate governance of public firms? SOX requires public companies registered with the SEC and their auditors to annually assess and report on the design and effectiveness of internal control over financial reporting. SOX also established the Public Company Accounting Oversight Board (PCAOB) to provide independent oversight of public accounting firms. 2. What are the components and principles of COSO ERM 2017 framework? COSO ERM 2017 offers five components with 20 principles that are applied in the process of strategic decision-making through performance measurement, at all levels and across all functions of the organization. See below the components and principles of COSO ERM 2017. 5 Components

Governance & Culture

Strategy & Objective Setting

Performance Review & Revision Information Communication & Reporting

20 Principles 1. Exercise board risk oversight 2. Establish operating structures 3. Define desired culture 4. Demonstrate commitment to core values 5. Attract, develop and retain capable individuals 6. Analyze business context 7. Define risk appetite 8. Evaluate alternative strategies 9. Formulate business objectives 10. Identify risks 11. Assess severity of risks 12. Prioritize risks 13. Implement risk responses 14. Develop portfolio view 15. Assess substantial change 16. Review risk and performance 17. Pursue improvement in ERM 18. Leverage information and technology 19. Communicate risk information 20. Report on risk, culture, and performance

3. Two commonly used frameworks developed by COSO are COSO 2013 internal control framework and the COSO ERM 2017 framework. What are the differences between the two frameworks?

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

COSO 2013 focuses on internal controls. It is a general framework with 17 principles to provide a benchmark for most companies to evaluate their internal controls. Internal control is an integral part of enterprise risk management. COSO developed the ERM framework to help companies evaluate risk and opportunity with a broader view on risk management to maximize firm value. `ERM identifies potential events that may affect the companies. ERM manages risk to be within the companies risk appetite. ERM provides reasonable assurance regarding the achievement of the firm’s objectives. 4. Use a few sentences to describe IT general controls and application controls. Give a few examples of these two types of controls. IT general controls (ITGC) relate to enterprise-level controls over IT. Most general controls limit access to the IT systems and prevent unauthorized use. Examples: Passwords, Anti-virus software, Disaster Recovery Planning, change management process. IT application controls are activities specific to a subsystem’s or an application’s input, processing, and output. Examples: Closed-loop Verification, Validity Check, Batch Totals 5. What elements of COBIT framework would a manager be inclined to use as a guide for IT governance and management? Why would they be used? COBIT provides a supporting tool set that bridges the gap among IT control requirements, technical issues, and business risks. The COBIT framework: • provides a business focus to align business and IT objectives; • defines the scope and ownership of IT process and control; • is consistent with accepted IT good practices and standards; • provides a common language with a set of terms and definitions that are generally understandable by all stakeholders; and • meets regulatory requirements by being consistent with generally accepted corporate governance standards (e.g., COSO) and IT controls expected by regulators and auditors. 6. ISO 27000 series serve different purposes from ITIL. Which one could be more important to accounting professionals and why? ISO 27000 series could be more important to accounting professionals. ITIL is a framework focusing on IT infrastructure and IT service management. ISO 27000 series is a framework for information security management. ISO 27000 series, particularly ISO 27001 and ISO 27002, have become the most recognized and generally accepted sets of information security framework and guidelines. The main objective of the ISO 27000 series is to provide a model for establishing, implementing, operating, monitoring, maintaining, and improving an Information Security Management System (ISMS).

7. Segregation of duties is an important internal control. What functions must be separated? If ideal segregation of duties is not economically feasible, what are some compensating controls that would help reduce the risk of fraud or error? The general guideline for segregation of duties (SOD) is that transaction authorization, record keeping and asset custody should be separated from each other. If ideal segregation of duties is not economically feasible, supervision can be used to mitigate the risk posed by imperfect segregation of duties. The supervising individual might be a superior within the organization, or in the case of a small business the owner of the firm. 8. Use a flowchart to explain the risk assessment process.

9. There are three types of controls: preventive, detective, and corrective. List some examples of each type. Explain which type of control auditors would focus on while evaluating a company's effectiveness of controls and why.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

Preventive controls are designed to deter problems before they arise. Preventive controls require compliance with preferred procedures and thus stop undesirable events from happening. Examples: closed-loop verification, validity check. Detective controls find problems when they arise. These controls are procedures and techniques designed to identify undesirable events after they have already occurred. Examples: bank reconciliations, monthly trial balances. Corrective controls fix problems that have already occurred and been identified; These can include activities such as using backup files to recover corrupted data. Detective controls are often linked to accompanying corrective controls to remediate any issues that are discovered. Examples: Disaster Recovery Planning, periodic backups. 10. Describe the control activities in the COSO framework. Why are these control activities important for most firms? Control activities are the policies and procedures that help ensure that necessary actions are taken to address risks to achieving the firm’s objectives. There are two categories of control activities: physical controls and IT controls. Physical controls are mainly manual but could involve the physical use of computing technology. IT controls involve processes that provide assurance for information and help to mitigate risks associated with the use of technology. A firm must establish control policies, procedures, and practices that ensure the firm’s objectives are achieved and risk mitigation strategies are carried out. Control activities occur throughout a firm at all levels and in all functions.

Problems (Note – Problems with “Connect” in parentheses below are available for assignment within Connect.) 1. The global economic crisis in years 2008 to 2010 has stimulated many boards of directors and executives to reevaluate how they assess and manage risks. Use a flowchart to describe the process of risk assessment.

2. A newly hired internal auditor discovered that immaterial thefts by employees are pervasive in the company; employees take books from the company’s library, tools from the company’s laboratories, supplies, products, etc. By interviewing with some of the employees, the internal auditor discovered that most employees thought their behavior was not detrimental to the company as each item did not have significant value. What should the company do to prevent this type of employee behavior?

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

The company should set the tone at top and influence the control consciousness of its employees. Employees should be educated on integrity and ethical values of the company as well as the company’s policies. Ongoing monitoring can also be done to prevent and detect immaterial thefts. 3. The sales department of a company received several claims from its customers that their payments were not credited to their accounts. Investigation uncovered that the accounts receivable clerk has been stealing some of customer payments. What are some of the internal control procedures that could prevent and detect the problem? Segregation of Duties. Record keeping and asset custody should be separated so that one person cannot have access to remitted payments and be responsible for recording the customers AR balances. Send out monthly statements to customers to confirm their balances and reconcile differences. 4. (Connect) The information system of Carlsbad Bottle Inc. is deemed to be 90% reliable. A major threat in the procurement process has been discovered with an exposure of $300,000. Two control procedures are identified to mitigate the threat. Implementation of control A would cost $18,000 and reduce the risk to 4%. Implementation of control B would cost $10,000 and reduce the risk to 6%. Implementation of both controls would cost $26,000 and reduce the risk to 2.5%. Given the information presented above and consider an economic analysis of costs and benefits only, which control procedure(s) should Carlsbad Bottle choose to implement? Expected benefit of an internal control = Impact × Decreased Likelihood Control A: 300,000 × (10% − 4%) = 18,000 = 18,000 Control B: 300,000 × (10% − 6%) = 12,000 > 10,000 Control A&B: 300,000 × (10% − 2.5%) = 22,500 < 26,000 Carlsbad should implement control B. 5. Which internal control(s) would you recommend to prevent the following situations from occurring? a)

Authorization of a credit memo for a customer’s account (on receivables) when the goods were never actually returned. Documents and records (must require a receiving report before authorizing a credit memo) b) Theft of funds by the cashier, who cashed several checks and did not record their receipt. Segregation of duties (record keeping and asset custody) c) Inventory was stolen by receiving dock personnel. The receiving clerk claimed the inventory was sent to the warehouse but the warehouse clerk did not record properly.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

Supervision, independent verification, and documents and records to track custody of goods and determine responsibility. d) Writing off a customer’s accounts receivable balances as uncollectible in order to conceal the theft of subsequent cash collections. Segregation of duties (transaction authorization and asset custody) e) Billing customers for the quantity ordered when the quantity shipped was actually less due to back-ordering of some items. Documents and records (cross check the sales order and the packing slip to check whether the quantity ordered is the same as quantity shipped; bill a customer on quantity shipped) 6. (Connect) Which types of input controls would best mitigate the following threats? a) Posting the amount of a sale to a customer account that does not exist. Authorization (for sales transactions) or the use of a validity check on the customer number. b) A customer entering too many characters into the five-digit zip code while making an online purchase, causing the server to crash. Size Check c) An intern’s pay rate was entered as $150 per hour, not $15 per hour. Reasonableness Check d) Approving a customer order without the customer’s address so the order was not shipped on time. Completeness Check e) Entering the contract number of a critical contract as 13688 instead of 16388, which is a serious mistake to the company. Check Digit Verification

Discussion Questions 1. Phishing is a type of social engineering. Give two examples of phishing. An email that requests the victim to log into a website that looks legitimate but is actually controlled by the attacker. An attacker clones a legitimate website and distributes a broken link to victims in an attempt to convince them to enter sensitive information. 2. If social engineering is a common reason that confidential information was revealed, what needs to be done to prevent this from occurring? User training is often employed to counter social engineering attacks. By teaching users the dangers of social engineering and establishing a policy governing the dissemination of any information like login data, the users will be much more knowledgeable if a social engineering attempt is made. 3. What is the goal of each of the general security objectives (e.g., confidentiality, integrity, availability, access control)? Why should a company care about these? Confidentiality: the goal of confidentiality is for information to not be accessible to unauthorized individuals or processes. A company should care about keeping the confidential data of its clients, users, customers, and visitors private; due to the risks of litigation, regulation, reputation, and security."

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4th edition

Integrity: the goal of data/information integrity is for information to be accurate and complete. That is, it has not been degraded or impaired by unauthorized manipulation or hardware failure. Companies should care about the integrity of the data/information that they use to support decision making. Availability: Information and systems are available and accessible on demand. Conversely, companies should be concerned that only authorized users have access to systems and data. Access Control: Limits access to systems and information to only those individuals, by nature of their job responsibilities, that require access to it. Companies must be very concerned about access controls enforcement, to maintain the CIA of the data. 4. There are restrictions on how U.S. companies store and share customer data. For health care providers, HIPAA is designed to protect patient data. A handful of states require companies processing customer payments to comply with PCI-DSS. Search the Internet for more information about these regulations and discuss the major requirements of each. PCI-DSS and HIPAA both establish standards for protecting and disseminating personal identifiable information (PII). They establish frameworks for data security management that must be complied with to either participate in electronic card transactions or store electronic patient records. Standards cover topics such as establishing a secure infrastructure, monitoring network and security information, and guaranteeing access controls are established. 5. Consider the following scenarios and identify the incentive, opportunity, and rationalization that exist that would enable a person to commit fraud: a. A manager increases the value of inventory in the computer system so she can show higher cost of goods sold. As a result, she embezzles the additional income. b. A college student pirates a newly released movie over the Internet. c. An employee creates a new vendor account for his spouse and submits invoices for services that were never performed. A. Incentive: Could be disgruntled employee, financial pressures, etc. Opportunity: as manager, she has access to a higher level of programs in the system Rationalization: Mindset that excuses the fraud as “OK” or “Justified” B. Incentive: the student needs funds to pay college tuition, room and board bills. Opportunity: The student gained access to the movie as it was mistakenly available online and was able to download it before it was pulled offline. Rationalization: Mindset that excuses the fraud as “OK” or “Justified” C. Incentive: He and his spouse need funds for any number of reasons. Opportunity: Employee has access to the vendor center due to a lack of access controls enforcement in the company. Rationalization: Mindset that excuses the fraud as “OK” or “Justified”

6. What are the differences between authentication and authorization? Authentication ensures that users are who they claim to be. Authorization is the level of permission to interact with system resources granted to each individual. 7. Explain how to use the asymmetric-key encryption method to maintain confidentiality in transmitting a business document electronically? 1) The sender encrypts a challenge message with the receivers public key 2) Receiver decrypts with his own private key, answers the message, and sends the response encrypted with their own private key 3) Sender decrypts the message with the receivers public key and validates the challenge message 4) The process is reversed to authenticate the sender. 5) Either the sender (or the receiver) generates a symmetric key (called session key because it is valid for a certain timeframe only) to be used by both parties. 6) Use asymmetric-key encryption method to distribute the session key. 7) After both parties have the session key, use the session key to transmit confidential data or information. This is because using symmetric key for encryption is faster in data transmission. 8. What is hashing? Does it serve the same purpose as encryption? Why? Hashing is a one way process that turns a document (or a dataset) of any length into a key of fixed length. The process cannot be reversed and is used as part of validation of data integrity or to generate a message digest to encrypt as part of the digital signature process. Hashing does not serve the same purpose as encryption. Encryption is reversible (the cybertext can be decrypted) and the main purpose is for confidentiality. 9. How can data integrity be ensured when conducting e-business? Why is it critical to e-business? Data integrity can be ensured by comparing a message digest created by the sender with that generated from the sent over document. If the two hashes match, then the message has not been altered. 10. The previous chapter identifies COBIT and ISO 27000 as information security frameworks. How do they relate to GTAG’s Vulnerability Assessment? What similarities and differences exist among these three? The main objective of the ISO 27000 series is to provide a model for establishing, implementing, operating, monitoring, maintaining, and improving an Information Security Management System (ISMS). COBIT is a more general IT governance framework that considers the governance of a firm’s entire IT infrastructure. COBIT does not go into as much detail on security issues as ISO 27000, however, the two standards may be implemented together to improve corporate IT governance. GTAG’s Vulnerability Assessment is a vulnerability approach as opposed to a risk assessment process, where vulnerability management is a tactical short-term approach. COBIT 8

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4th edition

and ISO 27000 are more risk assessment based, requiring a more comprehensive tong term approach that may take many months or years to implement. 11. Disaster recovery planning (DRP) and business continuity management (BCM) help businesses manage security risks. What similarities and differences exist between these two approaches? A disaster recovery plan seeks to allow the business to quickly recover from a catastrophic event, while a business continuity plan is related to ensuring that the business can continue activities during conditions that would otherwise cause a service outage.

Problems (Note – Problems with “Connect” in parentheses below are available for assignment within Connect.) 1. Compare and contrast symmetric-key and asymmetric-key encryption methods in conducting ebusiness. Why do companies prefer one method over the other? If a company chooses to use both methods, what might be the reasons? How can the company truly use both methods for e-business? Answer: Asymmetric key encryption is very slow but allows for only 2 keys to be needed per user. Additionally, asymmetric key encryption can be used to authenticate users. Symmetric key encryption is much faster, but requires a separate key for every pair of users. In addition, these pairs must be physically distributed to users no matter how greatly dispersed. This is not an effective practice for an e-commerce company. Most companies will utilize both of these methods. The company will establish a connection to its users utilizing asymmetric key encryption and generate a symmetric session key to conduct all further business. 2. Many internal auditors and IT professionals believe wireless networks and mobile devices pose high risks in a firm’s network system. Collect information to examine whether this concern is valid. If so, identify the risks and the general controls to help reduce these risks. Answer: A company should have all of its mobile devices require VPN’s into the company’s network if it allows them to connect at all. This can allow a mobile device to connect through an un-trusted wireless network. The company should also keep any of its own wireless networks separated physically from the wired more secure networks that business is conducted through. 3. Under PKI, Certification Authority (CA) plays a critical role in the success of maintaining information security. Search the Internet to find a few public firms that are CAs. Compare these firms and provide suggestions on how to choose a CA as part of information security management. Answer: DigiCert: A large organization approved by several government organizations. 9

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4th edition

VeriSign: Part of Symantec; a large public security firm that is a trusted in the security industry. When selecting a PKI CA provider, it is important to focus on trustworthiness and proven history of security and confidentiality. In addition, the provider must possess sufficient resources to meet your needs. As always, third party service providers should have reports available to its customers providing third party assurance over the security of its systems. 4.

8. Internal auditors are often tasked with testing vulnerabilities. How would you suggest testing for system intrusion, logical access control, natural disasters, and intentional destruction of information? Answer: System intrusion: • Broad Detection Range: Internal auditors should measure the ability of the system to detect different type of intrusions. o Work with a 3rd party IT team to try to hack the system. • Economy in resource usage: Internal auditors should also measure the consumption of computer resources by the intrusion detection system. • Resilience to stress: Auditors are supposed to look at operational impairment in the case of high computing activity. Logical access control:  The company has formal policies and procedures for logical access, physical access and IT security.  Requests for New or Revised Access Form are approved by the Department Manager.  Administrator access to active directory, application and database is limited to authorized personnel.  Department Manager performs access review for applications and the active directory domain.  Event logging is activated and configured per policy.  All employees are required to have three things to access the system; something they have, know and are. Testing is done to see if system can be accessed without one of these three items. Natural disasters:  The company should develop an IT disaster recovery plan. It begins by compiling an inventory of hardware (e.g. servers, desktops, laptops and wireless devices), software applications and data. The plan should include a strategy to ensure that all critical information is backed up.  Vendors should be able to provide “hot sites” for IT disaster recovery. These sites are fully configured data centers with commonly used hardware and software products. Subscribers may provide unique equipment or software either at the time of disaster or store it at the hot site ready for use.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4th edition



It’s better for the company to have access to more than one facility. Hardware at an alternate facility can be configured to run similar hardware and software applications when needed. Assuming data is backed up off-site or data is mirrored between the two sites, data can be restored at the alternate site and processing can continue. Agreement with another company of similar size in a different location to utilize their system as a database backup. Agreement could include doing the same for the “sister” company.

Intentional destruction of information:  Periodic testing and evaluation of the effectiveness of information security policies, procedures, practices, and security controls to be performed with a frequency depending on risk, but no less than annually.  A process for planning, implementing, evaluating, and documenting remedial actions to address any deficiencies in the information security policies, procedures, and practices of the organization  Procedures for detecting, reporting, and responding to security incidents  Plans and procedures to ensure continuity of operations for information systems that support the operations and assets of the organization.  Frequent and regular tests to ensure information is present. Knowledge of this process could deter destruction of information.  Keeping important information with limited access. Or in a situation where two people must be present to access.  System Configuration Review: Internal auditors should conduct a review of how the system is configured. (GTAG, Auditing Application Controls, IIA) o “Review the three-way match system parameters” o “Query the underlying programming code of the application report generation process for appropriate logic” o “Rerun the query to compare the report to the one management generated” 9. Browse the Internet to identify some recent cases related to system availability. What are the risks and issues in system availability of these cases? Indicate possible controls to mitigate the risks. Answer: Students’ answers may vary. Typical risks are: • Unauthorized access to the system leads to system intrusion and data corruption. • The more complicated the system, the longer it takes to restart it. Hence, outages that require system shutdown and restart can dramatically affect your ability to meet a challenging availability target. • A support person who is called in afterhours could easily take an hour or two simply to arrive to diagnose the problem. • Unsuspecting users opening e-mails that appear genuine and without viruses • From the Cisco article: “Analysts add that most of existing tools track individual pieces of hardware, or take samples of information flows rather than tracking every packet of data. Because of Cisco’s central position in hardware plumbing, the information they have “gives 13

you granularity that no one has ever had before,” said Zeus Kerravala, an analyst at ZK Research.” Possible controls to mitigate risks: Test the Change Control Process Applications are always evolving to fit new business requirements and improve behavior. Even mission-critical applications change over time. Because the change control process is a large source of downtime-causing errors. A business- or mission-critical application must not go into production until it can be repeatedly performing error free change control. Test Catastrophic Failure Before deploying new application, companies should make sure that the catastrophic recovery procedures are created work as expected. Is the recovery team ready? It must be trained, equipped, and well-rehearsed. The plan is not useful if the recovery plan is not effective. Test for Resource Conflicts  Availability engineering requires in-depth consideration of an application's interactions with other system processes. Auditors must look at how a particular service is provided, evaluate all the ways some other application might interfere with the intended service, test for conflicts, and possibly consider design alternatives.  Update system belong the Secure E-mail Gateway (SEG) and educate employees through training to identify scams. Be clear about communicating how information will be requested and be consistent in following your own policies.  From Cisco article above: “Security is a key focus. One reason companies struggle in stopping network attacks is the constant changes in where they originate, which make it hard to keep a list of suspicious machines or internet addresses to block.  Cisco said its new technology makes it easier, instead, to enforce a “white list” of authorized systems, so that servers can only accept connections from approved devices and no others.” 10. Consider each of the following fraud cases. Identify the incentive, opportunity, and rationalization present in each case. a. An employee of a telecommunications firm’s payroll department moved to a new position within the department in which she no longer has privileged access to payroll accounts. However, when changing positions, her access rights to the payroll accounts were left unchanged. An associate told her that he was starting a financial service business and needed some contact information. Using the privileged access rights that she had retained, the employee provided her associate with confidential information of many employees, including 401k account numbers, credit card account numbers, and social security numbers, which he then used to commit more than 100 cases of identity theft. The insider’s actions caused more than $1 million worth of damages to the firm and its employees. b. A database analyst of a major check authorization and credit card processing company went beyond his authorized computer access rights. The employee obtained his firm’s consumer information of 8.4 million individuals. The stolen information included names and addresses, bank account information, and credit and debit card information. He sold the data to telemarketers over a five-year period.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4th edition

c. An IT consultant working under contract for an offshore oil platform company was denied an offer for a permanent job with the same company. He then accessed the firm’s computer systems without approval and caused damage by impairing the integrity and availability of data. d. A manager responsible for payment authorization hired an offshore programmer to insert a couple of independent contractors to the vendor table of his company’s database. He then authorized payments to the independent contractors on fictitious services for personal gain. He spent the stolen money on luxury items and extravagant purchases for himself, his family, and friends. Answers: a. Incentive: The insider’s action involves more than $1 million worth to the firms and its employees. The employee may be jaded that her new position no longer has privileged access to payroll accounts. This may have been felt as a demotion. Opportunity: When changing positions, her access rights to the payroll accounts were left unchanged. She realizes her access rights were not changed. She may not have received training that indicated this would be unacceptable behavior. Rationalization: She was an employee of payroll department and hence she might feel it is not wrong to access to those payroll accounts. She may have felt she HAD to give this information to the associate if he was in a higher position of responsibility. b. Incentive: He could sell 8.4 million consumers’ information to telemarketers over a five-year period. Opportunity: The data analyst has been authorized with computer access rights to 8.4 million consumers’ information. The analyst was not authorized, but apparently had the capability to extend his computer access rights. Rationalization: Being a database analyst, he might feel it is acceptable and justifiable to sell that information to external parties. He probably rationalized that if it was not secure enough to keep him out why would it matter if he sold the information. c. Incentive: He was able to access the firm’s computer systems without approval and thus he was able to revenge the company for not offering a permanent job to him. Deny an offer of permanent employment after working as a consultant. Opportunity: He was able to access the firm’s computer systems without approval and caused damage even as a contractor. Since he was an IT contractor he already know the companies systems well and had the capability to access the data. Rationalization: As an IT consultant, he might feel it was easy for him to conceal his action and caused damage without being notice. He may have felt that the company deserved these actions since they did not value him. d.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4th edition

Incentive: He could authorize payments on fictitious services for personal gain and spent money for himself, his family and his friends. The incentive is the luxury items and extravagant purchases for himself, family, and friends. Opportunity: He had the opportunity to authorize payments to the independent contractors on fictitious services. The opportunity arises from having access to an offshore programmer who can hack the system to input vendors in a way unrelated to him. Rationalization: He might feel that he is the manager and would not be caught for fraudulent payment authorization. As a manager he may feel that he is authorized to use the funds however he sees fit as long as it appears that it is being used for business purposes. Or maybe he feels he deserves a better lifestyle and is currently underpaid.

Discussion Questions 1. What are the main reasons for using a VPN? There are several reasons for an enterprise to use a VPN: a. The enterprise would like to connect widely dispersed offices without leasing a direct, private line from its service provider. The use of a VPN allows the company to securely simulate a WAN environment using the otherwise unsecure internet. b. The company would like geographically dispersed employees to be able to access the company network to work remotely. This can be particularly desirable for personnel such as outside sales representatives who, due to the nature of their jobs, are often on the road away from the secure corporate LAN. c. VPNs are cheaper than leased lines. d. Companies are able to maintain high levels of productivity as would be achieved using a LAN with a widely dispersed workforce. 2. Consider the computer attacks in the previous chapters. How would a VPN protect a user from one or more of them?

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

The VPN encrypts data so that only the VPN can interpret it. So, if the data is intercepted by a hacker it will lack meaning. 3. We often use regression analyses in data mining. Are accountants required to understand data mining? Why? Data mining is becoming a requirement for accountants as investors are demanding continuous auditing. Continuous auditing relies on data mining to see if trends in ratios are shifting indicating that fraud could be occurring. 4. What is the main purpose of using firewalls? Search over the Internet to find its importance for cybersecurity. a. Firewalls are intended to prevent certain types of unwanted data packets from entering the enterprise’s network. This activity can prevent certain types of network intrusion such as a message bearing a telnet (an unsecure remote connection protocol) command. They are generally not sufficient to protect an enterprise network alone but can be an integral part of a company’s IT security plan. b. The main purpose of using a firewall is to prevent rejected data from entering or leaving a company’s private network. This is done by using accept and reject rules to filter the incoming or outgoing data. Firewalls can provide protection against cyber-attacks by protecting networks from malicious or unnecessary network traffic. “Firewalls can also prevent malicious software from accessing a computer or network via the internet. Firewalls can be configured to block data from certain locations (i.e., computer network addresses), applications, or ports while allowing relevant and necessary data through.” https://www.cisa.gov/uscert/ncas/tips/ST04-004 (accessed 12/8/2022) 5. Firewalls rely on a list of allowed and blocked services and locations. What would happen if a company's firewall rules were too weak? If the firewall rules were too strict? a. If a firewall’s rules were too weak, hackers could access the company’s servers, obtain, destroy, corrupt or take data. b. If a firewall’s rules were too strict, employees would not be able to efficiently complete their work, if at all, as their access would be so limited. 6. Are there differences among hubs, switches, and routers? a. Hubs, switches, and routers connect computers to other computers through ports, or connectors. b. Hubs are simple, cheap, and unintelligent. All data that is put in, is sent out to all other computers. Whatever response is made by the computer is sent back to the hub and sent to all other computers. c. Switches learn locations. Each data that enters the switch teaches it where it originated and is destined. Any response will only be sent to the location of origin. This location will be remembered for future use. This enhances efficiency. d. Routers are smart, complicated, and can serve as a firewall. They are programmed to understand, manipulate as needed, and route data. They learn locations just like switches. They also perform Dynamic Host Configuration Protocol (DHCP) and Network Address Translation (NAT). During DHCP routers assign IP addresses externally and internally. NAT is how the router assigns IP addresses to external computers. It then only accepts responses

from computers to which local computers initiated communication. This is how they serve as firewalls. 7. Identify a few critical security issues in using a wireless network. a. Eavesdropping b. Man-in-the-middle c. Masquerading d. Message modification e. Message replay f. Rogue access points g. Traffic analysis h. Denial of service attacks 8. Using a brute-force attack, hackers can crack the password to a WEP access point in about 5 minutes. WPA2 in about 2 days. What does this tell you about the security of wireless networks? Wireless networks are only as secure as the complexity of the algorithms that protect their authentication and encryption. 9. Auditors are constantly developing new CAATs analyses to help them in the assurance process. Use a search engine to identify some of the techniques that are being used currently. a. Filter and Display Criteria b. Aging c. Expressions and Equations d. Join and Relate e. Gaps f. Trend Analysis g. Statistical Analysis h. Regression Analysis i. Duplicates j. Parallel Simulation k. Sort and Index l. Benford’s Law m. Summarization n. Matching o. Stratification p. Combination of One or More https://www.aicpastore.com/Content/media/PRODUCER_CONTENT/Newsletters/Articles_2 010/CPA/Jan/CAATS.jsp (accessed 7/7/2016) 10. When would an auditor prefer to conduct a black-box audit? A white-box audit? a. Black-box audits are preferential when an auditor is determining how well a network will hold up to an attack from an external source which knows nothing about the internal structure of the company.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

b. Auditors would prefer a white-box audit if there are suspicions of internal fraud or to determine weaknesses in the internal control environment. 11. Continuous auditing allows auditors to validate data and monitor transactions in near real-time. What advantages does this provide to auditors? What are some potential problems with continuous auditing? a. Advantages i. Prevent and catch fraud early ii. Reduction of errors iii. Catch breakdown of internal controls and recommend response to management iv. Increase operational effectiveness v. Enhance compliance with laws and regulations vi. Increase management confidence in control effectiveness and financial information vii. Monitor transaction data in a timely manner viii. Understand critical control points, rules, and exceptions, ix.Performance of control and risk assessments in real or near real time x. Reduction of routine testing xi.Increase focus on investigation activities b. Potential Problems i. Expensive ii. Alterations of previously audited data iii. Collusion of auditor due to regular engagement with client iv. A breakdown in independence due to formed relationship v. Disruptive of business operations 12. Auditing an accounting information system requires knowledge and skills in both accounting and computers. However, most auditors may not have sufficient expertise in the technical side of computing and information systems. Given today’s business environment, how much computer- and information systems-related knowledge and skills must an auditor have to be effective in performing auditing? a. Auditors need to have a working knowledge of the ERP system in which financials are audited i. If an auditor does not know the weaknesses of an ERP system, they will not be able to pinpoint where fraud may be occurring ii. Employees who use a specific system will know how to manipulate it well b. Auditors will need to know how to query and recreate queries of databases c. Auditors will need to understand strengths and weaknesses of the security of the information system and what are quality tests d. Auditors will need to understand how cloud-based technologies alter the workplace environment and security

4. (CIA adapted) As an internal auditor, you have been assigned to evaluate the controls and operation of a computer payroll system. To test the computer systems and programs, you submit independently created test transactions with regular data in a normal production run. Identify advantages and disadvantages of this technique. This is not the preferred method of testing the production system. The auditor has disrupted the integrity of the data system by entering what is essentially false data into the live database. The data that is entered is now part of the legal records of the company even though it is not real. This could be construed as fraudulent data entry. If the auditors were concerned about the production environment, they should have analyzed the real payroll transactions to determine if any of them would adequately fulfill the test objectives and monitored those real transactions. If tests still need to be entered, the auditors should utilize the Quality Assurance environment.

5. Describe how an auditor would use each of the following audit techniques: ITF, parallel simulation, EAM, GAS. a. Integrated Test Facility: uses auditor live master files which are placed into the live client system. Test transactions are run so that only the auditor’s files are affected. b. Parallel simulation: is used to reprocess client data in the auditor’s GAS. The output is compared to the client’s actual output for verification. c. Embedded Audit Module: is used to continuously audit a client by embedding a sequence of code into the client’s system. This code monitors transactions and creates a log of suspicious items. https://www.aicpa.org/interestareas/frc/assuranceadvisoryservices/downloadabl edocuments/whitepaper_evolution-of-auditing.pdf (accessed 12/8/2022) d.

Discussion Questions 1. Using Exhibit 14.2 as a guide, name three internal and three external databases that you think should be included in a data warehouse for Bank of America, Wells Fargo or your local bank. Support your answer. Internal Databases might include the following: General Ledger Loan Portfolio (Including loan products) Vendor Database Potential Customer Database Current Customer Database (and related demographics) External Databases might include the following: General Economy Information (GDP, Interest Rates, etc.) Focal Customer Demographics 3

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

Banking/Finance Industry Information Data warehouses are made for different purposes. The databases proposed above presume an interest in selling new loan products to existing and potential customers. We get profitability information of the various loan products from the internal databases. We also get information on potential customers, economic and industry trends from the external databases. In sum, these databases can spot trends and opportunities for a bank. 2. Using Exhibit 14.2 as a guide, name three internal and three external databases that you think should be included in a data warehouse for your university. Support your answer. Internal Databases might include the following: Student Recruitment Database Student Course Catalog Database Student Performance Database (include ACT, SAT, high school grades, college grades) External Databases might include the following: General Economy Information (GDP, Interest Rates, etc.) Focal Student Demographics University Industry Information Data warehouses are made for different purposes. The databases proposed above presume an interest in gathering information to attract the highest quality students to a university. Getting information on recruitment means, scholarships, grades, and courses taken might all be helpful in attracting prospective candidates. Information can also be gleaned from external databases to learn trends of universities, students (via focal student demographics) and the general economy. All of this information might be helpful in attracting students to a university. 3. Name five items that you think would be included in a digital dashboard for ESPN or for Disney. Why are these critical business processes for them? A digital dashboard for ESPN might include the following:  Current viewership/subscribers (Last two weeks and trends from recent months)  Advertising Revenues (Last two weeks and trends from recent months)  Current game/conference contracts in progress  Current website hits/Fantasy Football, Baseball etc. game participation  Status of negotiations with various cable subscribers. This dashboard is meant to capture the status of operations, advertising and new game revenues for ESPN. A similar solution might be rendered for Disney. 4. Who will rely on XBRL data for decision making? Why is assurance needed on XBRL data? Support your answer. XBRL might be used by investors, financial analysts, regulators, and creditors (banks, etc.). As these various XBRL users rely on the information to make important decisions, it is important that the XBRL data be accurate. Thus, assurance is needed for XBRL data in addition to the financial statements underlying that XBRL data.

5. Why is there a different XBRL taxonomy for each country, including XBRL Australia, XBRL Canada, XBRL Germany, XBRL Japan, XBRL-Netherlands, XBRL-US, and XBRL-UK? What would happen if there were only one XBRL taxonomy for all countries? Different countries have different financial standards (IFRS, FASB, country-specific) and have various practices that are reflected in their XBRL taxonomy. Moreover, there are also tags and extensions that are company-specific to reflect the business model used by that particular company. As financial standards converge toward a harmonized standard (such as IFRS), there is increasingly a chance that one XBRL standard emerge. However, since XBRL is also used for regulatory purposes (such as taxes, banking, etc.) that is country-specific, it is not realistic to expect that a single world-wide standard to emerge. A sole XBRL taxonomy for all countries would allow users to be able to access data from around the world in a similar fashion, allowing economy of effort, etc. 6. How would the XBRL style sheets be different for financial analysts as compared to the Securities and Exchange Commission? How would XBRL style sheets be different for a firm’s web site as compared to bank loan officers? Style sheets used by financial analysts would be used in models supporting earnings and cash flow predictions. The SEC, in contrast, would be more interested in protecting investors as well as disclosure and regulatory issues and providing fraud analysis. The style sheets supporting these models would thus be quite different. The XBRL style sheet for a company web site might only access the highlights for the retail investor. In contrast, the XBRL style sheet for bank loan officers would attempt to assess ability to pay back a loan and would tailor their style sheet to access that information that allows them to monitor liquidity and solvency. 7. Why is XBRL needed in the financial community? In your opinion, why did the Securities and Exchange Commission mandate its usage? What does it provide that was not available before XBRL? XBRL is needed as a means to rapidly and efficiently information to the investing public, including all financial statement users. An explanation as to why the SEC might be interested is that it quickly and efficiently allows the SEC to gather data for its own usage to ensure that a thorough disclosure is available to the investing public. 8. Why would XBRL be used for internal uses such as management accounting? Hint: See Exhibit 14.5. Just as information is useful for external purposes, XBRL allows management to collect an extensive amount of disaggregated that might be used for internal purposes. As the firm’s financial and non-financial information is automatically tagged by either the enterprise system (e.g. SAP) using XBRL GL or tagged manually by professionals knowledgeable of the business, this information might be used for managerial accounting purposes. Moreover, XBRL might be the means of organizing management accounting information. 5

9. Why do companies need both internal and external databases in a data warehouse? Firms work to collect data that will be useful in optimizing performance. Data helpful to address the questions or provide support for decisions can come from a variety of sources both internal and external to the firm. A data warehouse therefore, will keep data from internal and external databases in such a way as to be ready for the analyst to gather, analyze and provide important information that might be useful for decision making. 10. How is a digital dashboard different from a financial report? A digital dashboard tracks a firm’s process or performance indicators or metrics to monitor critical performance. The data for the digital dashboard may come from the financial report but may also track other non-financial indicators as well.

Problems (Problems with “Connect” in parentheses below are available for assignment within Connect.) 1. Using Exhibits 14.1 and 14.2 as guides, name four internal and four external databases that you think should be included in a data warehouse for marketing function of Procter and Gamble or the consumer packaged goods company with whom you are most familiar. Procter and Gamble has products like Gillette razors, Charmin Tissue and Head and Shoulders Shampoo. Why are these eight databases you recommend critical to the effective functioning of the marketing department to sell more products? Support your answer. Internal Databases might include the following: General Ledger – to help determine basic profitability of various products Customer Database (and related demographics) – to learn more about who buys Point-of-Sale Sales Data (who purchases, where and at what price points) Inventory Data (What products are available for sale, which have new innovations, etc.) External Databases might include the following: General Economy Information (i.e., GDP, Interest Rates, etc.) Focal Customer Demographics (what are important product characteristics for the consumer) Competitor Information (e.g., Unilever, Nestle, Kraft, etc.) Retail/Consumer Packaged Goods Industry Information 2. Which of the four predicted assurance needs do you believe is most critical to ensuring XBRL accuracy? Support your answer. The four predicted assurance needs in the near future include the following:  The most current, standardized XBRL taxonomy is used,  The underlying financial and nonfinancial data that is used in XBRL tagging is reliable,  The XBRL tagging is accurate and complete, and  The reports generated using XBRL are complete and received on a timely basis. While all are four are important and require assurance to ensure XBRL accuracy, the third one with assurance that the selection of the appropriate XBRL tags is appropriate and complete is arguably the most important to ensure XBRL accuracy. Answers will vary. 6

3. XBRL allows disaggregated data to be presented to interested external parties. Financial analysts often forecast earnings many years ahead and then suggest whether an investor should buy, sell or hold a stock. Which type of disaggregated data do you think financial analysts would be most interested in receiving when predicting one-year ahead earnings? Detailed sales data, detailed expense data, detailed asset data and/or detailed liability data? Support your answer. In your opinion, which disaggregated XBRL data would be most useful information in predicting whether an investor should buy, sell or hold a stock? Answers will vary. It is arguable that to come with up with a forecast of earnings, the detailed sales and expense and cash flows data would be most relevant as they would most directly lead to predictions of year-ahead data. Of course, depending on the nature of the underlying company and the balance sheet implications of the company, the detailed asset and liability may also be of importance. 4. The effectiveness of data mining has been criticized by the Wall Street Journal. In one article, the author notes that academic studies have shown that by using data mining, analysts could accurately predict changes in the stock market based on either the population of sheep in Bangladesh, or the number of nine-year-olds at a given time, or whether it is smoggy on a given day.1 While the statistical correlation may be valid, there must be a logical reason that a particular factor will predict stock returns. Required: a. Do you think these findings represent valid relationships or spurious correlations? While there may be a statistical association between smoggy days and stock market returns, such an association is a spurious correlation. Common sense suggests that smoggy days do not predict stock market returns. b. What measures do you think might be valid predictors of stock market returns? Macroeconomic forces and accounting earnings are associated with annual stock market returns. A company that produces incremental profits in the current or unexpected prospects of profits in the future years, those companies will generally experience positive stock returns. 5. XBRL touts as its primary advantage that it will increase efficiency for the firm and those interested in its business reports. Required: a. How is XBRL more efficient for the firm that reports its business performance? Does the use XBRL GL in a firm’s accounting software make XBRL more or less efficient than when XBRL GL is not used? XBRL in and of itself may not make the reporting company more efficient in how it codes the data. However, the ultimate ability of XBRL to put the XBRL database in one location and let others access it for their particular needs will make it more efficient.

The use of XBRL GL makes it so the company will only have to code its information once directly into the XBRL GL package. b. How is XBRL more efficient for those using its business reports for regulator, investing or other purposes? The users (such as regulators, investors, etc.) simply need to develop a style sheet to extract their reports from various companies via the GL. Developing one style sheet for multiple companies is much more efficient than inputting specific numbers from many companies and then analyzing them separately. c. Are there any cases when it is less efficient to use XBRL? If XBRL is not an integral part of the financial reporting or if its tagging is an add-on process, it will certainly make the company less efficient. 6. How would Coca Cola use business intelligence to monitor Pepsi Cola’s operations in Russia? What sources of data need to be gathered? How would it be analyzed? Coca Cola could monitor Pepsi’s marketing campaigns, business operations, production, new factory production, capital expenditures, pricing structure, and sales (among other things) via its business intelligence. Business intelligence might be gathered using a web crawler, which systematically browses the Internet including such sources as press releases, internet chat rooms, web sites, google hits, blogs, annual reports of bottlers, electronic commerce web sites, etc. Once the information has been gathered, the data should be analyzed to discern patterns or trends. Are prices of PepsiCo products increasing? Are they looking at new locations to build a factory, etc.? Based on the information gathered, decisions can then be made by Coca Cola as a strategic response to what Pepsi is doing in Russia. 7.

The patterns we find are correlations, but not necessarily causation. Every time we see a link between the occurrence of one event or action with another, we generally assume that one event or action caused the other. But simply linking one occurrence with another does not always prove that the result has been caused by the other. For example, such data mining might suggest the following relationship between arcade revenue and computer science doctorates awarded in the USA, with a correlation of 0.985.

Discussion Questions 1. Bitcoin was introduced in 2009. The total bitcoins that exist today is much more than the total bitcoin amount in 2009 or 2010. How can this happen? Answer: A new block is being added to the blockchain roughly every 10 minutes. When a new block is added, the system awarded the successful miner with new bitcoins. Hence, the overall number of bitcoins grew at the speed of the system generated coins every 10 minutes. 2. Since bitcoin uses blockchain technology and is cheaper than the traditional way of doing business, why is bitcoin not an accepted by many government agencies? Answer: One feature that led to the popularization of Bitcoin is that its transaction are anonymous. Bitcoin is a public blockchain which allows everyone to join the network and examine the transactions. However, the parties in the transaction records are represented by the addresses of the owners, not by the real identities. The government agencies forbid bitcoin payment since real identities are almost always required by these agencies. 3. Why is Ethereum a better choice over Bitcoin for business related applications? Answer: Bitcoin is a peer-to-peer, cryptocurrency application. It only deals with bitcoin currency transactions. Ethereum, on the other hand, introduces smart contracts which incorporate business rules to transfer assets. Furthermore, since smart contracts are designed to be programmable, they are able to serve all kinds of industries. Obviously, Ethereum is a much better choice for business related applications. 4. What are the three types of blockchain? What are major differences amongst these blockchains? Answer: public blockchain, private blockchain, and consortium blockchain. Differences: public blockchain has no access restrictions to the viewing and participation in the blockchain network. This type of blockchain is not allowed in many industries, such as finance. In the financial industry, permission is usually required to join the network. This type of blockchain is called private blockchain or permissioned blockchain. Instead of using proof of work for validation in public blockchain, transaction data and validation are restricted in private blockchain. Consortium blockchain is a permissioned blockchain but the participants constitute multiple organizations. In addition, the consensus protocol is executed only on a limited set of trusted nodes for consortium blockchain. 5. You have been tasked with forming an audit and assurance team to work with companies that have adopted Blockchain technology. What skill sets will you emphasize when choosing your team members and why? Answer: It is important for your team members to understand the terms mentioned in blockchain technology such as distributed ledger, mining, consensus, immutability, proof of work, proof of authority, Bitcoin, Ethereum, Hyperledger, and R3 Corda etc. In addition, Ethereum and other blockchain applications use smart contract to represent business rules. It is important for the audit and assurance team to understand how business rules are represented

in smart contracts and to make sure that the business conduct is compliant with government agencies. 6. Recently, over 20% of companies surveyed indicated they were testing or considering artificial intelligence applications in their business but only 4% were actively using AI. Why do you think companies a) are interested in AI, and b) are having trouble implementing AI? The interest in AI follows from the belief that AI will increase revenues or reduce costs. The implementation problems could be several: lack of data, lack of data science skills, long development cycles. 7. Review the five basic questions that AI/machine learning can answer. Develop additional business questions for each question. a. Is this customer likely to buy? Is this transaction fraudulent? Should we hire this applicant? b. Is this user name and password suspicious? Is this contract risky? Are revenues for this store in line with other stores? c. What is the value of goodwill? How much is this used car worth? d. Which types of inventory will be attractive to this customer? Which types of songs would this person like? e. How much should we bet now? Where is the stock market going next? 8. Visit the websites of major accounting firms. Search for what they are doing with AI/machine learning? How do you think this will impact the accounting profession over the next 10 years? Open-ended question, but the answer should address changing skillsets, changing mindsets. 9. Give examples of process automation applications. Both analytic process automation and robotic process automation are examples of process automation. Alteryx is designed for analytic process automation. Alteryx can automate the processes of data extraction, filtering, blending, and analytics that enables computer and business professionals to manage and manipulate scientific/business data from various data sources. Applications such as UiPath, Blue Prism, Automate Anywhere and Power Automate are typical applications for robotic process automation (RPA). In general, RPA is a software technology automating any repetitive tasks for digital transformation.

Answer: E Discussion Questions 1. Consider a company that competes on price, such as Walmart, in comparison to a company that competes on other factors, such as Starbucks. Describe how their Balanced Scorecard objectives and the corresponding measures would differ across the four perspectives. In answering this question, the students should recognize that the fundamental reason for differences between Wal-Mart and Starbucks is that they have different value propositions. Wal-Mart aims to compete on price, while Starbucks competes on other value proposition factors, such as quality, availability, relationship, and brand image. Since Wal-Mart seeks low prices, their business processes must be structured to minimize costs. Starbucks, on the other hand, is more focused on creating a consistent customer experience at all its stores. Students should be encouraged to consider differences in the value proposition require differences in the importance of specific processes, as well as differences in the learning and growth perspective. 2. One criticism of the Balanced Scorecard is that it can lead to information overload by measuring too many performance indicators. Do you agree with this criticism? Why or why not? Students should consider the impact of balanced scorecard measures in a multi-divisional, multilevel organization. Since the balanced scorecard typically requires measurement of performance along four perspectives, a multi-division organization could need to collect information on numerous measures to assess performance. However, the balanced scorecard also requires organizations to select the relatively few, most important, measures for each organizational element. Some divisions may only be responsible for managing one or two measures. So, while the possibility of information overload exists, the judicious use of the balanced scorecard should avoid the development of more measures than can be easily managed.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

3. If a company does not want to implement a formal Balanced Scorecard performance management system, is it still beneficial for the company to develop a strategy map? Why or why not? Students should recognize that organizations do not need to implement a comprehensive system to measure performance to benefit from articulating their strategy in a strategy map. The map is a communications tool that allows managers to discuss and clarify performance cause-and-effect relationships. This is especially true when the organization is considering changes. The strategy map augments capital budgeting techniques by placing proposed investments in the context of the organization’s strategy. 4. Some companies create a Balanced Scorecard by taking some current objectives and key performance indicators (KPIs) and assigning them to the four Balanced Scorecard perspectives. Describe the advantages and disadvantages of that approach. Students should recognize that any well-managed organization has formed objectives and key performance indicators. They need to know whether they are meeting their objectives. So, their existing systems already collect information about their key performance indicators. Thus, the advantages of using current objectives and KPIs are several. They exist, they are already measured, and systems do not need to be changed. Conversely, the disadvantages would relate to the way that the existing objectives and measures were developed. It is likely that they are not truly balanced in terms of leading and lagging indicators and internal and external perspectives. It is also possible that the organization has not clearly linked the KPIs in a series of cause-and-effect chains aligned with their overall strategy. Additionally, organizations may form KPIs based on the ease of collecting the information, rather than the true importance of the KPI to their strategy. 5. Does the Balanced Scorecard framework provide a performance measurement system or a performance management system? Why? The students could develop arguments for both: the balanced scorecard framework provides a performance measurement system as well as a performance management system. In truth, one requires the other. Measures provide feedback on the organization’s performance with respect to its objectives. This feedback allows management to improve what the organization is doing or, in some cases, revisit the strategy. 6. A biotech company is considering developing an IT system that will track the progress of its drug compounds through the Food and Drug Administration (FDA) approval process. Describe, as specifically as possible, how that IT initiative might affect performance across all four Balanced Scorecard perspectives. The answer should describe a chain of cause and effect relationships. The biotech company investment in an IT system to track drug approval is an example of an investment to improve information capital (Learning & Growth Perspective). Such an investment would support the biotech company’s innovation processes (Internal Process Perspective) and allow them to manage resource allocation within that process. The innovation process links to elements of the 8

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

biotech company’s value proposition, such as product availability, product quality, and product function. Successfully addressing those value proposition factors would attract new customers (Customer Perspective) and grow revenue (Financial Perspective), which in turn would increase shareholder value. 7. A company is developing key process indicators (KPIs) for the information capital aspect of its learning and growth. It is considering measuring the amount spent on information technology hardware and software as its measure. What advice would you give it about that choice? Students should describe the strengths and weaknesses of using the amount spent on information technology and software as a KPI for the development of information capital (Learning & Growth Perspective). A strength of this KPI is that the investment should increase the organization’s information processing capability, and most organizations cannot improve their information systems without new investment. However, KPI weaknesses relate to whether the investments are aligned with the organization’s strategy. Do the amounts spent on IT technology and software address important requirements? 8. Outline a Balanced Scorecard for your business school. How would using your Balanced Scorecard system affect the management of the school? It is more difficult to develop a balanced scorecard for a non-profit organization, since they do not have shareholders and customers in the for-profit sense. Students should start with defining the business school’s stakeholders and then describe elements of the value proposition that the school delivers. Then, they should describe the internal processes that deliver the school’s value proposition while also controlling costs. Finally, they should describe the kinds of investments in human capital, information capital, and organizational capital to support ongoing improvements to the internal processes. 9. Describe likely differences in a Balanced Scorecard between a for-profit company and a not-forprofit (or governmental) organization. Which perspectives are each organization more likely to focus on? This question is closely related to the previous question. Students should recognize differences in stakeholders and goals of the stakeholders. For-profit shareholders seek increased value, but non-profit stakeholders have other objectives. So, students could argue that the two external perspectives would be substantially different. The two internal perspectives, however, could be similar. 10. The CEO of a midsized company is considering purchasing an ERP system but may not have fully considered the other changes that the company needs to make to maximize the value of the system. Using a Balanced Scorecard framework, create a strategy map that describes how the ERP system could benefit company performance with the right set of complementary changes. ERP systems require complementary changes in business processes to create value. To make those changes, the organization could also need changes in human capital necessary to put the right people in place to make the best use of the system. These changes to the Learning & Growth Perspective would allow the organization to improve processes, which in turn allows 9

improvements to the value proposition while controlling costs. Ultimately, the organization should see improvements to financial performance (Financial Perspective). The students strategy map should look something like the following:

11. Consider a large, Fortune 500 company. They are probably too complicated for one business model canvas. What advice would you give them about how to divide up their business into multiple business model canvases? The answer depends on the company, but in general, the answer should address the homogeneity of the value proposition as well as the nature of the customer segment. 12. Name a company that sells to a mass market customer segment. What are some characteristics of that company’s products? The answer depends on the company, but consumer goods, for example, sell to the mass market. These products usually compete on price, marketing, image, availability, and functionality. Think of toothpaste, breakfast cereal, etc. 13. Name a company that sells to a niche market customer segment. What are some characteristics of that company’s products? Niche market retailers usually sell relatively few types of products to a specific customer segment. One example is Lululemon apparel; another is Harley Davidson motorcycles. Their products are designed to appeal to their target customer group, so the value proposition would focus on image and uniqueness but not price. 14. Name a company that segments their customer segment. What are some characteristics of that company’s products? Segmented markets require different versions of the product line for each segment. Hotel chains offer different hotel brands to attract different customer segments. For example, Hilton

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

owns Doubletree, Hilton Garden Inn, Hampton Inns, Embassy Suites, etc. Each brand provides a hotel designed to appeal to a customer segment based on price, features (such as suites), locations. Problems (Note – Problems with “Connect” in parentheses below are available for assignment within Connect.) 1. The answer to this question depends on the company that the student chooses. Students will find that it is relatively easy to find financial and customer perspective information. We find that students can usually find an abundance of information on the company’s value proposition from the company’s press releases. It will take more work to find information on the company’s internal business processes, although the business press often describes business processes more completely than the company itself does in its financial statements (e.g., in the MD&A). Perhaps the most difficult task is to find information about Learning & Growth. Again, the business press may be most helpful here. 2. As described above, it will be difficult to find specific information about these companies’ Learning & Growth investments. The students should be encouraged to think about the unique culture of their company and how that culture affects how the firm conducts its business processes. One other aspect that can generate discussion is the role of incentive compensation (investments in human capital) and how incentives affect employees’ alignment with company goals and commitment to improving business processes. 3. The answer to this question depends on the company selected. The main issue that affected Bank of America during the recent economic crisis related to mortgages, especially mortgage loans to customers that may not have been fully creditworthy. Goldman Sachs problems relate to how they marketed mortgage-backed securities to their customers and whether they knew the problems with those securities when they sold them to their customers, e.g., banks and investors. AIG, a large multi-national insurance company, was involved in the credit default swaps and collateralized debt obligations. These products were sold to customers to insure those customers against losses. Of course, when customers incurred substantial losses, AIG could not honor its insurance obligations, and the corresponding liquidity crisis led to U. S. government intervention to bail out AIG. In all these cases, the companies emphasized revenue generation without dealing with the corresponding risk. Thus, students should be encouraged to define where the companies should have considered the risk. 4. (Connect) The strategy map should look something like the following:

Discussion Questions 1. An important first step in the economic justification process is to assess business requirements. How would the Balanced Scorecard framework presented in Chapter 16 help companies assess their business requirements for IT? The balanced scorecard framework helps companies assess their business requirements for IT by placing the investment in a cause-and-effect structure. A strategy map could show how the proposed investment either reduces business process costs (the process perspective) or improve the organization’s value proposition and thereby lead to revenue growth (customer and financial perspectives). It also helps mitigate alignment risk by showing how the investment is consistent with the organization’s strategy. Additionally, it can reduce change risk by helping identify required training and employee incentives necessary to support the process changes necessary to make the IT effective. 2. Chapter 16 described three types of IT: function, network, and enterprise IT. Consider the diagram shown in Exhibit 17.2. Which type of IT is likely to have the greatest impact on business performance? Which type of IT would require the most complementary changes? Why? All three types of IT could affect business performance; however, the enterprise IT by its nature would seem most likely to have the greatest impact. Enterprise IT technologies restructure interactions within the organization as well as with external partners, while Network IT technologies simply allow people to communicate with one another, and Function IT technologies support single, standalone functions. Similarly, since Enterprise IT often results in changes to business processes, those technologies would require the most complementary changes. 3. The benefits of an IT initiative should be measured in comparison to the revenues and costs that will occur if the IT initiative is not implemented. What issues would a project team face when making this comparison? How does it affect the team’s assessment of risks? The benefits of an IT initiative should be compared to the revenues and costs expected if the IT initiative is not implemented. The biggest issue faced in making this comparison is that an IT project is most likely to exceed expected costs while also failing to achieve expected benefits. Thus, the evaluation team should carefully test the sensitivity to cost overruns as well as the failure to achieve benefits. In other words, the team should pay careful attention to project risk and financial risk. 4. Use Microsoft Excel to assess the NPV of an IT initiative. The initiative will require an initial investment of $250,000 in year zero and is expected to return $150,000 per year for the next 3 years. Assume a discount rate of 10 percent. What is the NPV? How does the NPV change if the discount rate is 15 percent? Describe how changes in the discount rate assumption can affect the NPV. EXCEL solution (using NPV function): =NPV(rate, return1, return2, return3)-initial Initial investment (made in year zero) Returned amount 1st year

–$250,000 $150,000 5

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

Returned amount 2nd year Returned amount 3rd year Discount rate Discount rate NPV at 10% NPV at 15%

$150,000 $150,000 10% 15% $123,028 $92,484

Higher discount rates result in lower NPV 5. Use Microsoft Excel to assess the internal rate of return for an IT initiative. Suppose the initial investment is $60,000 in year zero. The returns on investment in dollars for the following 5 years are (a) $10,000, (b) $12,000, (c) $15,000, (d) $21,000, and (e) $26,000. Use the IRR function to compute the internal rate of return after 2, 4, and 5 years. Next, assume that the initial loan is for $70,000 at 8 percent and you are earning 16 percent on the annual returns. Use the MIRR function to calculate the internal rate of return. Is the annual rate of return higher when using the MIRR function than the IRR function? Under what circumstances would it be lower? EXCEL solution (using IRR function and MIRR function) =IRR(initial, year1, year2, …) Year 0 1 2 3 4 5

Cash Flows Cash Flows –60000 –70000 10000 10000 12000 12000 15000 15000 21000 21000 26000 26000

IRR after 2 years IRR after 4 years IRR after 5 years

–46.18% –1% 10%

–50.84% –6% 5%

MIRR

12.35%

8.93%

The MIRR would be lower if the reinvestment return is less than the finance rate 6. Consider two projects. Project 1 costs $262,000 and returns $60,000 per year for 8 years. Project 2 costs $390,000 and returns $70,000 per year. Project 2 is determined to be less risky, so your company only requires an 8 percent minimum annual return compared to 10 percent for project 1. What is the NPV of each project? What is the absolute maximum that the company should consider investing in each project? EXCEL solution (using PV function for PV of return per year) =PV(rate, nper, pmt)

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

Project 1 Initial investment (made in year 0 (immediately) Return per year Number of years Discount rate PV of initial investment PV of 8 years annual return NPV

Project 2 –$262,000 $60,000 8 10%

–$390,000 $70,000 8 8%

($262,000.00) $320,095.57 $58,095.57

($390,000.00) $402,264.73 $12,264.73

Maximum initial investment –$320,095.57 –$402,264.73 The results would differ if the initial investment is assumed made during the 1st year rather than immediately. 7. Your company has just completed a major IT initiative and is reviewing the outcome. It notes that the project took 3 months longer than expected. As part of the project, the company wanted to use some automatic bar code readers, but the rate of correct bar code reads was below the expected rate. Although managers were worried about employee acceptance of the new system, it appears that the employees have embraced it and, as a result, are making it work better than expected. Refer to Exhibit 17.4 and identify how these results address the risk categories listed in the table. The major IT initiative took longer than expected and the bar code readers did not work as well as expected. However, the employees unexpectedly embraced the change and made the technology work better than expected. This situation provides an example of Project Risk (the project will not be completed on time) and Technological Risk (the technology will not deliver expected benefits). The technological risk is mitigated by employee commitment to the use of the technology. The project risk was not mitigated. 8. Moore’s law suggests that computing power for the same cost doubles every two-and-a-half years. A combination of Moore’s law and the commoditization of computer components has made it possible to buy a $500 computer today that is more powerful and portable than a similar offering that cost $2,000 just a few years ago. How does this affect planning for major IT projects? Moore’s law suggests that costs will decrease and computing power will increase. The affects IT planning, since delays could reduce costs and option new technological options. It also suggests that current technology will become obsolete fairly quickly, so the payback should be over a short time frame. 9. Rank the ten core principles of effective information technology planning in order of importance in your opinion. Provide support for your top five important principles. Answers will vary.

End of Chapter Solutions Manual: Richardson, Chang, Smith, Accounting Information Systems, 4 edition

While all of the core principles of effective planning are important, it could be argued that the following are the most important.  RELEVANT SCOPE — The overall scope of the planning phase should be established to facilitate formulation of effective strategies.  BENEFITS REALIZATION — Costs of implementation should be justified through both tangible and intangible benefits that can be realized. The expected benefits should be bigger than the costs.  ACHIEVABILITY — The planning phase should recognize the capability and capacity of the firm to deliver solutions within the stated planning timeframe.  ACCOUNTABILITY — Identification of those responsible for implementing the plan should be explicitly clear.  COMMITMENT — Management commitment to the plan’s implementation should be clear and evident. The relevant scope helps us make sure there are bounds on the project. Basically, management knows what is needed to be done and will know when the project is complete. Benefits realization makes sure that the project benefits are greater than the costs and there is still a reason to do the project. Achievability makes sure we can do what we expect to do. That the results will actually be achievable. Accountability suggests knowing who is in charge and who will be implementing the plan. Having accountability is critical to an IT project, especially when follow up is needed by the project sponsor. Having commitment from management for the project and a clear project sponsor is critically important to garner the necessary resources and buy-in from the company. 10. Imagine the role of the project sponsor when a leader of the accounting bookkeepers comes to complain that the new information system could possibly result in the loss of five bookkeeper jobs. The bookkeepers argue that they will get the union involved if needed to protect their jobs. What should the project sponsor do? One possible direction the project sponsor could follow would be to explain that technology is continuing to change our world. To keep current positions, companies need to save where they can and this new technology allows the company to save money, yet keep some bookkeeper jobs, instead of having them outsourced to another company, or even India. While the loss of bookkeeper positions will be painful, especially for those who lose their jobs, keeping the company efficient and lean is also important for the company. 11. Explain the 100% rule. Assume you are telling your roommate about this rule and use an example that is relevant to him or her. The 100% Rule, therefore, requires thorough and complete project planning, that is, during the planning phase, being able to define all of the tasks, including all of the internal, external, and interim tasks. Perhaps a relevant example would be planning for a hiking trip and having every task planned in advanced, from packing a poncho to making sure food is included (as well as emergency provisions in case you get lost on your trip), to preparing for the weather (like rain). 8

These same tasks are required during project management to make sure all contingencies are planned and scheduled to allow complete communication of the needed project support to the project sponsor. The more thorough the planning, the less cost and time overruns will be experienced even when the unexpected occurs. 12. Compare and contrast a PERT chart and a Gantt chart. How do they complement each other? The PERT and the Gantt charts each have strengths and weaknesses. As was pointed out in the chapter, The PERT chart is sometimes preferred over the Gantt chart because it clearly illustrates task dependencies. On the other hand, the PERT chart can be much more difficult to interpret, especially on complex projects. When used together, they overcome these deficiencies and complement each other. 13. Using the 15-15 Rule as a guide, when would a project manager and/or project sponsor proceed with completion of a project even if it is both 15 percent over budget and 15 percent off the initial schedule? The 15-15 Rule states that if a project is more than 15 percent over budget or 15 percent off the desired schedule, it will likely never recoup the time or cost necessary to be considered successful. If the project is mission critical or related to a key competency of the company, it will likely be completed even if it is over budget and 15 percent off the initial time schedule.

3. a. One stated goal for Starbucks Digital Ventures is to “enhance the customer experience.” On its face, that is clearly a difficult goal to measure. Starbucks provides it digital ventures services, e.g., online content, free Wi-Fi, to customers at the retail outlets for free. Thus, there is no direct revenue connection and improvements to customer satisfaction resulting in sales growth are hard to measure. Additionally, customers are influenced by the human interaction with baristas and various forms of marketing in general, so it is difficult to identify the cause of sales increases unambiguously. It is also possible that certain customers who visit Starbucks to take advantage of free internet access could crowd out higher paying customers. Consequently, the digital ventures services could reduce sales; however, it is inherently difficult to measure lost sales. b. Despite the problems outlined above, Starbucks indicates that it does measure ROI on its digital ventures. For examples, Starbucks creates special offers via its digital services and then tracks how many customers take advantage of those special offers. Additionally, it uses data about customer preferences to structure special offers that the customer is most likely to be interested in. Finally, Starbucks expects that there is a strong correlation between the time that customers spend in the store and the amount that they spend per visit. By using the special offers, coupons, QR codes, etc., it can track whether or not their expectations are true. 4. Initial investment Discount rate

Although the depreciation expense affects the income statement, it is not relevant for this analysis, since we've already considered the initial investment. c. When the discount rate increases to 15%, the net present value of both projects decreases and Project 2 now has a negative NPV of approximately –$5,800. Project 1 remains the preferred project when considering NPV, although the NPV for Project 1 is marginal (approximately $564). The IRR for Project 1 is approximately equal to the discount rate and the IRR or Project 2 is below the discount rate. d. When the discount rate decreases to 6%, the net present value of both projects increases. The NPV for Project 2 now exceeds the NPV for Project 1, although the IRR and payback periods for both projects remain unchanged. A lower interest rate makes Project 2 more attractive. e. For technology investments, it is common to see a delay before realizing benefits, so Project 2 seems the more likely scenario. 5.

14. As part of effective IT planning in systems development life cycle, a return on investment (ROI) calculation may be performed as part of the economic feasibility analysis. Often, many of the benefits from a new information system may be intangible benefits (e.g. system is easier to use or system enhances customer service, etc.) that are hard to quantify in an income statement. How would you suggest this be included in the economic feasibility analysis? Sometimes ROI is computed only using hard dollars and may underestimate the total return. In order to include the intangible benefits, it may be important to clearly state what advantages are expected to occur and why they are expected to occur. If there is a quantifiable benefit, it should be real clear that this is just an estimate and how the estimate was derived. Intangible benefits are often the most important returns, so in our view, they should be included in the analysis. 15. In the chapter, we discussed an example of Starbucks using the systems development life cycle to develop the capability to analyze what type of pastries sell best with its various hot and cold drinks. Now, let’s suppose that NASDAQ requires all of the firms trading on the exchange to report their financial statements not only using GAAP but also International Financial Reporting Standards (IFRS). Since Starbucks’ current system cannot handle the IFRS requirements, the financial reporting system must be modified. Using Starbucks as an example, explain what types of activities would occur in each of the five phases of the systems development life cycle in preparation for reporting financial results according to IFRS. Starbucks is traded on NASDAQ, so we’ll use them as the focal company to answer this question. The planning phase of the SDLC begins with a business need for a new or better information system. In the case of Starbucks, if they hope to continue to list on NASDAQ and NASDAQ requires IFRS as well, it would appear that a future business case is not needed. The analysis phase of the SDLC involves carefully analyzing the needs of the end user and refining project goals into carefully defined functions and operations of the intended system. A system that reports U.S. GAAP (FASB) standards in addition to IFRS, the analysis is relatively clear. However, it is important to build in some flexibility so that perhaps the system would be useful for financial preparers to do a what-if analysis to show how various transactions would affect both the financials under U.S. GAAP (FASB) and IFRS. Starbucks may also want to consider the functionality of the system to make sure it is user friendly, etc. The design phase of the SDLC involves describing in detail the desired features of the system that it uncovered in the analysis phase. Starbucks should design the needed features in in detailed screen layouts, business rules, process diagrams, pseudo code and other documentation to ensure that it is user friendly and gets the needed information in as efficient a

Richardson, Chang, Smith – Accounting Information Systems, 4th Edition – Chapter 17

manner as possible. The design should also ensure that it meets NASDAQ standards and the reports needed for that formatting. Implementation: The implementation phase of the SDLC involves development, testing and implementation of the new proposed system. The Starbucks systems developers write the computer code and test it. Maintenance: The maintenance phase of the SDLC is the final phase of the SDLC and includes making changes, corrections, additions, and upgrades (generally smaller in scope) to ensure the system continues to meet the business requirements that have been set out for it. The Starbucks system has continuous and regular maintenance to ensure that it meets the NASDAQ requirements for IFRS. 16. Accountants generally do not have all of the necessary systems analyst and systems development skills needed to develop accounting information systems. Why should you be interested in project management of an accounting information system? Understanding the various phases of the SDLC and what systems analysts and systems designers may help accountants to communicate their needs to those designers. Systems analysts and designers may also not understand the important need of internal controls associated with financial reporting systems. To the extent that accountants can understand the system and help design that system, they can help address those internal controls. Not surprising, there is quite an active and potentially lucrative market for those that have both accounting and systems skills. To the extent this interests you and jobs are available, it may make sense to take further courses in this area and prepare for a career as an IT auditor, among other designations discussed in chapter 1. 17. For your personal consulting business, you decide to set up an accounting information system to help with taxes as well as to help monitor your revenues and expenses. You’ve heard that the QuickBooks is easy to set up, so you buy it, install it on your computer, enter in recent transactions and begin to use it. Required: 1. Explain one or two ways you could be a user of this accounting information system. (Hint: Use the discussion in the text considering the role of accountants in accounting information systems.) As a user of the AIS, disaggregating the sources of revenues and expenses would be of critical importance. Also consistent with one of the themes for chapter 1, that accountants are business analysts, helping businesses to address subsequent business opportunities. 2. Explain one or two ways you could be a manager of this accounting information system. (One possibility: What practices do you employ to make sure your system is safe.) As you manage the AIS, you may want to establish certain practices to ensure the information in the system is accurate. This might include doing cash reconciliations between the AIS and the bank. You may want to ensure only certain individuals can access these accounts, or that it is not accessible from the Internet by others, etc.

Richardson, Chang, Smith – Accounting Information Systems, 4th Edition – Chapter 17

3. After a few months, you decide to expand your QuickBooks with additional modules (payroll, inventory, etc.). Access the QuickBooks website (http://quickbooks.intuit.com) and consider one or two ways you could be a designer of your accounting information system. You have many choices to consider on what modules are added and what functionality they have with the overall accounting systems. These choices affect the overall functionality of the system and add capabilities that may aid in the overall, efficient running of the business. 18. Brainstorm a list of reasons why 84% (including 53% challenged + 31% failed) of the information technology projects either failed or were challenged in 2021. Consider specifics of each of the elements of the triple constraints model and any other common delays including the challenges of working with programmers, software and hardware suppliers and vendors, etc. What is the best way to overcome these issues and decrease the number of projects failed or challenged? Potential Reasons For Failed or Challenged IT Project Scope creep? Incomplete work breakdown structure. Lack of consistent use of PERT and Gantt charts Improper communication between business users, systems analysts, systems designers and programmers. Unanticipated costs. Unanticipated problems with the software. Improper training Lack of training Lack of desired functionality Lack of Project Sponsor to get needed resources Use of the work breakdown structure where 100% of the tasks are identified and use of the PERT and Gantt planning tools, all would be helpful. A strong project sponsor that gets the needed resources for the project would ensure company support.

19. The PERT chart below represents the tasks to be done to implement a system. Can you think of other steps that should be included? Is there adequate time for training given the Technology Acceptance Model’s recommendation to focus on perceived usefulness and perceived ease of use? What is the critical path for this project? (Comp: Insert Chapter 15 Pert Chart in Problems here) It seems like more steps need to be taken to get user acceptance. Have they had enough time for the initial analysis of the business needs (or is that assumed to be already done)? Is there enough time for user acceptance? What happens at node 12? Do they have a further time period to test it out or it expected to be used? Will the old system be running at the same time to allow a transition period? The critical path, or longest path, is node 1 to 2 to 3 to 5 to 6 to 7 to 11 to 12.

Richardson, Chang, Smith – Accounting Information Systems, 4th Edition – Chapter 17

20. Consider the Triple Constraint figure in Figure 15.3. Why is quality included in that figure even if it is not a triple constraint? Why is quality a concern (or not a concern based on your point of view) for the project manager and project sponsor? While the triple constraints do need to be carefully addressed, some level of quality must be met to be useful to the firm, to gain user acceptance and actually be used. While oft times the focus for the project manager is that a project must be completed by a certain date or for a certain amount of money (cost) or both. But in many cases, just as important is that the deliverable (or result) of your project must also meet some minimum specifications (quality) to meet the firm’s intended purposes. 21.
