36) Describe the operations function's transformation process and provide an example for each element.

Answer: The transformation process view of operations management holds that inputs are transformed into outputs. Examples of inputs are raw materials, labor, capital, equipment, information, and intangible needs. The transformation process is the conversion of these inputs using either manufacturing or service operations (and sometimes both). Manufacturing operations might be painting, welding, machining, or assembling. Outputs of the transformation process are tangible goods, services, fulfilled needs, and satisfied customers. Specific examples may vary depending on the company chosen.

37) Distinguish between upstream and downstream firms in a supply chain and provide an example.

Answer: Upstream and downstream are relative terms that describe the position of a supply chain member from one point of reference. A supply chain member that is upstream from a firm is sending their output to the firm for use as an input. A supply chain member that is downstream from a firm is taking the firm's output and using it as an input to their own processes. It is possible for a single member of a supply chain to be both upstream and downstream from one or more members of their supply chain.

Examples may vary.

38) Distinguish between first-tier and second-tier suppliers in a supply chain and provide an example.

Answer: First-tier, second-tier, and any subsequent steps are measured relative to their position from a common point in the supply chain. All companies at a level (call it A) receive inputs from their first-tier suppliers (level B). These first-tier suppliers (at level B) in turn receive their inputs from their own firsttier suppliers (level C). These companies (level C) are considered second-tier suppliers of the companies at level A. Both tiers are upstream from level A, but level B is downstream from level C. Examples will vary.

39) Supply chains have been in existence for over a century. What is different about supply chains in the 21st century from those in existence 100 years ago?

Answer: The active management of supply chain activities is the big difference between supply chains in existence today and those of decades ago. Active management includes relationship management and an examination of the supply chain as a whole to optimize it from a global perspective. In the past, the production managers of each company in the supply chain were more concerned with the operation and financial well-being of their own companies, often to the detriment of other members of the supply chain.

40) Offer definitions of the operations function and the supply chain. What is the relationship between operations and supply chain?

Answer: The operations function is the collection of people, technology, and systems within an organization that has primary responsibility for providing the organization's products or services. The supply chain is a network of manufacturers and service providers that work together to create products or services needed by end users. These manufacturers and service providers are linked together through physical flows, information flows, and monetary flows. The supply chain has multiple actors, each of which has their own operations function — the output of one operations function is the input to the downstream partner's operations function, and so on across the breadth of the supply chain.

41) What are three reasons that the study of operations and supply chain management is important?

Answer: One reason that the study of operations management is important is that every organization must make a product or provide a service that someone values. Without this, there is no reason for the existence of the organization. The study of supply chain management is important because most organizations function as part of a larger supply chain. Finally, organizations must carefully manage their operations and supply chains in order to prosper. The better the supply chain and operations functions are coordinated, the greater chance for success of all members.

16) What is the most impactful trend in supply chain management over the last quarter century? Justify your choice.

Answer: The authors name electronic commerce as the greatest influence on business. Electronic commerce is the use of information technology solutions to automate business transactions. E-commerce promises to improve the speed, quality, and cost of business communications and can be used to coordinate a supply chain. Entire industries and countless business have developed thanks to the Internet and e-commerce. In the entertainment industry alone, Netflix has moved from a distributor of DVDs to a streaming service and the music industry has undergone a sea change in how new music is marketed and distributed. Answers may vary.

17) Of all the activities of supply chain management, which poses the greatest challenge and why? Cite examples in popular media.

Answer: The authors indicate that relationship management is the most difficult and therefore the most susceptible to breakdown. Poor relationships with any link in the supply chain can have disastrous consequences for all other supply chain members. An unreliable supplier can starve a plant, leading to inflated lead times and resulting in problems across the chain, all the way to the final customer. If organizations do not manage relationships with both upstream supply chain members as well as with their customers, they run this risk. If supply chain partners are separated geographically or culturally, or both, it is easy to have misunderstandings. In some cases, many components can be purchased only through foreign suppliers with proprietary knowledge. Examples will vary as time passes.

52) Electra wants to purchase a laptop for use in her MBA program so she can work on assignments and surf the web while the professor drones on endlessly. After consulting with her colleagues, she chooses the dimensions of cost, weight, processor speed, and touchscreen capability as critical to her long term success and amusement. She evaluates four different laptops and rates their performance on each criterion on a scale from 1 (poor) to 5 (excellent). She is struggling with her assessment of the importance of the Cost criterion. As an avid lottery player, she is pretty sure that tonight's drawing will result in at least a two number match on the ticket she bought on the way to class and it could mean a three-number match. Given her uncertainty, she would like to choose the laptop that performs the best overall across the entire spectrum of possibilities of the outcome of tonight's lottery. Which would you recommend?

Dimension Weight Speed Cost Touchscreen

Importance 3 5 ??

1

Sir Face 4 4 2 5

Toybook Air Knockoff 4 3 4 4 4 5 2 3

High Priced 5 3 1 3

Answer: The most robust choice is the Knockoff, as it is the top-ranked alternative for four of the five possible importance weights for the Cost criterion. Not only does it perform well in four out of the five possible values, but it should be noted that it does so in the most likely outcomes of the lottery drawing this evening. It is highly likely that Electra will not win the lottery, and assuming Electra is a financiallystrapped student, the Cost criterion should probably be weighted as a 5 (losing lottery, so money is tight) than as a 1 (winning lottery and therefore cost is not an important consideration).

This table shows the value index for each alternative under the five different importance values for the cost criterion. Highest scores are highlighted.

Alternatively, the data in this table can be graphed to illustrate the preference shift as the importance of cost varies.

Answer: The four generic performance dimensions of operations and supply chain activities are quality, time, flexibility, and cost. Quality includes all characteristics of a product or service that bear on its ability to satisfy stated or implied needs. Time has two basic characteristics: speed and reliability. Flexibility is a performance dimension that considers how quickly operations and supply chains can respond to the unique needs of customers. Cost covers a wide range of activities that companies categorize in many ways; typical cost categories include labor cost, material cost, engineering cost, and quality-related costs.

56) A university is evaluating options for an enterprise information system to replace their antiquated systems. The CIO has developed the following criteria: At a minimum, the system (or system provider) must be capable of: Technical support available 24/7 Have successfully installed and maintained systems in universities of similar size.

Beyond this, systems will be evaluated according to initial cost, annual maintenance and support costs, and ease of use.

The three companies that are vying for the university's business supplied the following information about their performance on these criteria.

Criterion Tech support 24/7 Installed base Initial cost Annual cost Ease of use

A 24/7 3 installations $2.3 million $100K 20 hours training

B 24/7 7 installations $1.9 million $125K 20 hours training

C 8-5 M-F 1 installation $1.25 million $75K 40 hours training

Create and analyze a graph showing each competitor's performance with regards to order winners and order qualifiers. Which firm should get the business and why? If you were consulting with the three potential system providers, what advice would you give each one?

Answer: Graph structure may vary, although all should indicate that provider C fails on the order qualifier regarding technical support. Students may defend company A and Company B as being reasonable choices. While A has a higher initial cost, it takes $25,000 less each year to maintain, a breakeven of 16 years. Company B has a greater installed base of systems, seven to three. Depending on the locations (and possibly identities) of the other installed systems, how funding is secured for the initial investment versus for annual maintenance, one option may be more attractive than another. Company C needs solid advice from a consultant regarding availability of support people; perhaps additional installations can justify increasing the availability of technical support. The amount or effectiveness of user training should also be addressed. Perhaps improved instructional design could reduce the amount of training time needed.

Which situation do you think is more natural, the eventual conversion from winner to qualifier or the static status of "once an order winner, always an order winner"? Justify your conclusions.

Answer: Answers and examples will vary. Some would argue that there is a gradual conversion of winners to qualifiers thanks to the nature of business competition. Students might also note that the nature of competition and advances in technology make this progression from winner to qualifier a very natural occurrence.

60) Describe the four stages of operations and supply chain alignment with business strategy.

Answer: The four stages of alignment are internally neutral, externally neutral, internally supportive, and externally supportive. The internally neutral stage is more of a defensive strategy, where management seeks only to minimize any negative potential in the operations and supply chain areas.

There is no effort made to link these areas with the business strategy. In the externally neutral stage, industry practice is followed with no effort made to link the operations and supply chain areas with overall business strategy. There is an assumption made that whatever works for competitors will work for the company. The internally supportive stage features recognition that operations and supply chain structural and infrastructural elements must be aligned with the business strategy. Operations and supply chain areas participate in the strategic debate. In the externally supportive stage the operations and supply areas do more than just support the business strategy – the business strategy actively seeks to exploit the core competencies found within these areas.

25) What are the two types of product-based layouts? What are their similarities and differences and their advantages and disadvantages compared with other types of layouts and processes?

Answer: A production line is a type of manufacturing process used to produce a narrow range of standard items with identical or highly similar designs. Production lines have several distinct characteristics.

First, they follow a product-based layout, where resources are arranged sequentially according to the steps required to make a product. The various steps are usually linked by some system that moves the items from one step to the next, such as a conveyor belt.

Second, items typically move through the production line at a predetermined pace. At each step in the process, equipment or people have a set amount of time to finish each task. By dividing the manufacturing process into a series of discrete, carefully timed steps, production lines achieve high degrees of equipment and worker specialization, as well as consistent quality and high efficiency.

Production lines are ideally suited to the high-volume production of a single product or of products characterized by similar design attributes, such as size, material, or manufacturing steps.

Production lines have two drawbacks, however. First, high volumes are required to justify the required investment in specialized equipment and labor. Second, lines are inflexible with regard to products that do not fit the design characteristics of the production line. When production volumes are low or product variety is high, other solutions are needed.

Continuous flow processes closely resemble production line processes in that they produce highly standardized products using a tightly linked, paced sequence of steps. The main difference is the form of the product, which usually cannot be broken into discrete units until the very end of the process. The nature of the product tends to make shutdowns and start-ups expensive, which discourages flexibility and encourages product standardization. And the highly technical nature of many continuous flow processes means that specialists are needed to control operations. The only responsibilities of direct laborers might be to load and unload materials and monitor the process. Continuous flow processes also tend to be highly capital-intensive and very inflexible with respect to changes in output levels.

26) What is a cellular layout and what are its advantages?

Answer: A cellular layout is a type of layout typically used in group technology settings; resources are physically arranged according to the dominant flow of activities for the product family. Group technology is achieved when clusters of machines and/or personnel are dedicated to the production of products (or service of customers) that are similar. A cellular layout reduces transportation and congestion on the production floor.

27) Draw the product-process matrix and discuss the placement of each process type Answer: The product process matrix relates output volume and degree of customization and shows which process types have the greatest chance for success in each combination of volume and customization. A job shop is best suited to make low volumes of highly customized (low standardization) products and a production line is best for generating large volumes of highly standardized products.

28) How can a supply chain operate with multiple different manufacturing processes linked across supply chain partners?

Answer: The constituent companies can each operate within the appropriate space on the Hayes and Wheelwright Product-Process matrix, which permits them to achieve an optimal fit for the output variety and volume. As each member of the supply chain sends and receives product from their adjacent partner, their only concern is that output rates are reasonably matched to avoid flooding each other with inventory or starving a downstream partner with insufficient inputs.

30) Why are process decisions important?

Answer: Process decisions are important because they tend to be expensive and far-reaching. A process choice dictates the type and size of the workforce, the type of equipment that is needed, and the type of products that can be made and kinds of information systems that are required to run the business.

Different processes have different strengths and weaknesses.

11) What are the four levels of customization and at what place does each occur in the supply chain?

Answer: The four levels ranked from least to greatest customization are make-to-stock, assemble-toorder, make-to-order, and engineer-to-order. Make-to-stock products have no customization and are typically produced in large enough volumes to warrant keeping a finished goods inventory. Assemble-toorder products are customized at the very end of the manufacturing process. Make-to-order products use standard components, but the final configuration of those components is customer specific. Engineer-toorder products are designed and produced from the start to meet customer requirements. Engineer-toorder products are customized upstream from design. Make-to-order products are customized downstream from material sourcing and upstream from fabrication. Assemble-to-order products are customized downstream from fabrication and upstream from assembly/finishing. The text indicates that make-to-stock products are customized downstream from assembly/finishing and upstream from distribution, although this customization may be only in the order quantity.

Answer: A service package includes all the value-added physical and intangible activities that a service organization provides to the customer. For some service operations, the primary sources of value are physical (or tangible) activities. In this case, management's attention must be directed towards capital expenditures, material costs and other tangible assets. For some service operations, the service package consists primarily of intangible activities. If this is the case, management should focus on training and retention of skilled employees and development and maintenance of the firm's knowledge assets.

20) Define the terms front room and back room and describe the roles these processes play in service operations. What must operations managers take into consideration when setting up these two processes?

Answer: The degree of customer contact determines the relative importance of front-room and backroom operations in a service process. The front room in a service organization is the point (either physical or virtual) where the customer interfaces directly with the service organization. As a rule, as the degree of customer contact increases, more of the service package is provided by front-room operations.

In designing front-room operations, managers must consider how the customer interfaces with the service. Layout, location, and convenience become key. The physical layout must be comfortable, safe, and attractive, and the location must be convenient. In addition, front-room service must be available when the customer needs it.

As the degree of customer contact decreases, more of the service package is provided by backroom operations.

The back room refers to the part of a service operation that is completed without direct customer contact.

The back room is often hidden from the customer's view. Such services can be located to reduce transportation costs and laid out to improve productivity.

Because back-room personnel do not deal directly with customers, the hours of operation are not as crucial as they are in front-room operations, and employees do not have to be skilled in dealing with customers. As you might expect, back-room service operations are usually easier to manage than frontroom operations.

21) Where should a business consultant position herself on the three axes of contact, customization, and cost.

Answer: Consultancy services are by their very nature, highly customized based on their clients' needs.

In addition, the degree of customer contact is high and the service package itself is typically intangible.

Consultant services are unique for each client, so the consultant often cannot realize efficiencies except in back office services — the true client-facing aspects of the business must be billed and monitored closely.

22) Which poses the greatest underlying managerial challenges — a service that is extremely high on customization, contact, and tangibility or perchance a service that is extremely low on contact, customization and tangibility? Provide an example of a service that fits each space and defend your answer.

Answer: Answers and examples will vary. Engineering consulting services are highly customized, contact, and often provide a tangible output. Commoditized services like cloud storage are the exact opposite. The commoditization permits economies of scale and an ability to forecast demand and standardize most customer interactions. While more effort is required to set this up, the day-to-day management of the process is perhaps easier than a service that rates high on all three axes.

33) Consider any collection of tasks to be assigned to stations in a line balancing exercise. Use the equation for determining the minimum number of stations to derive an upper bound on the efficiency of the actual line balance for those same tasks.

Answer: The minimum number of stations equation is ΣT/takt time. The heuristic requires that any noninteger result be rounded up to the next highest integer since a fractional station is undefined. The ratio of the result of the equation ΣT/takt time to the next highest integer provides this upper bound on efficiency. For example a calculation of 3.75 workstations is rounded to 4; the ratio of 3.75/4 = .9375 and 93.75% is the highest efficiency possible with that set of tasks and takt time.

Answer: The three types of processes are primary, support, and development. A primary process is one that addresses the main value-added activities of an organization. A process is value-added if a customer is willing to pay for the resulting outputs. A support process is one that performs necessary, albeit not value-added, activities. A development process is one that seeks to improve the performance of primary and support processes. Without development processes, a firm will become frozen at the point in time that development ceased. Customers go to a firm and reap the benefits of their primary processes and are often unaware of the firm's support and development processes. The firm must be keenly aware of all three, and apply development processes to primary and support processes in order to remain competitive and stay in business.

12) What is the general procedure for developing a swim lane process map?

Answer: The steps for developing a swim lane process map are similar to those for a more generic process map, with the exception that the symbols are aligned with different entities in the organization (or process) that are responsible at each step.

The steps are as follows: The entity that will serve as the focal point is identified. This can be a tangible good, a customer, a customer order, or any other entity of interest.

Clear boundary, starting, and ending points are identified.

The process map is developed by thinking about the elemental process steps that are performed. There is a tendency to use too much detail, so it is often helpful to take a macro view and then develop cascading levels of greater detail for portions of the process that are problematic. These process steps can be aligned with rows (or columns) that represent the organization's entities/departments to illustrate the handoffs that occur throughout the process. It is easier if the actual map is developed in two or three steps – first the macro view, and then the boxes representing potential participants are drawn on a blank sheet of paper.

The boxes are linked using arrows that indicate the type of flow and its direction Any boxes that do not have any arrows going in or out of them are removed from the map. New boxes may be added as needed.

After arrows are roughed out on the first copy of the map, the map may be redrawn to provide a good overview of the relationships between the various process participants.

13) What is the difference between a process map and a swim lane process map?

Answer: A process map identifies the specific activities that make up the informational, physical and/or monetary flow of a process. They use a standard set of symbols that are linked together in the sequence of operational steps. When a flow unit is passed from one department to another, there is no clear indication this transfer of ownership has taken place. A swim lane process map depicts the activities just like a process map, but arranges them in a series of rows, a single row for each owner of the action.

Answer: Define the goals of the improvement activity. Clarify how improving the process will support the business, and establish performance targets. This ensures that the team doesn't waste time on efforts that will not see a pay-off to either the customer or the business.

Measure the existing process. Develop a basic understanding of how the existing process works - the process steps, the people involved, current performance, and required data.

Analyze the process. Identify the relationships and factors that cause the process to perform the way it does, i.e., perform root cause analysis.

Improve the process. During this step, the team identifies ways to eliminate the gap between the current performance level and the performance targets established in step 1.

Control the new process. Work with the individuals affected to maintain the process improvements.

48) A tenured professor lights a cigar, cradles a snifter of brandy in his claw-like hand, and reviews his student evaluations from the previous semester. The numbers were unspectacular, but he beamed with pride as he read the comments. For the first time in a long time, no one responded to the "What can the professor do to improve the course?" question with the classic response "not teach it anymore." There were a number of comments, and since he took his craft seriously, he set about summarizing and organizing the comments into the alphabetical list you see here. Take this data and analyze it using the appropriate tool for continuous improvement. Then recommend to the professor the next tool (out of the tools for continuous improvement) that he should use to take the next step in this analysis.

Comment Can't understand the book Enjoyed the class Expect me to remember prerequisites Need more feedback on homework Prefer one class night a week Slow down Tests too hard Work more examples

Count 2 5 7 3 7 15 9 14

Answer: Given the nature of the data, a Pareto chart is the appropriate tool to examine the students' comments. Sort in descending order by Count and plot using the comments as major categories.

It would be entirely reasonable to combine the two leftmost categories – if the professor worked more examples, he would, in effect, move more slowly through the material. Combining these categories makes the Pareto effect more pronounced.

20 .

A Pareto chart provides an excellent starting point for a cause and effect diagram. The tallest bar is the effect that most customers are complaining about. Troubleshooting this element of his course will address the major issue most students have with his class and set him well down the path to Professor of the Year.

49) An assistant professor designs his fall semester class so that a major homework assignment is due the day his students waltz into class to take their first exam. The results are mixed so he rewrites his exam for the spring semester and repeats the process, again collecting a major homework assignment on exam day and grading and returning both the homework assignments and exams the following class meeting. Use an appropriate tool from the tools for continuous improvement to analyze the data. What conclusions do you draw?

Homework grade 2 5 13 14 16 16 19 20 22 28 29 30 31 33 36 38 57 59 67 67 72 82 98

Answer: The best tool for this occasion would be the scatter plot. Plotting exam score against homework grade yields some insight.

22 .

Since the homework is completed and due before the exam experience, it is reasonable to test whether performance on the exam depends on performance on the homework. This does not appear to be the case in the fall semester; as homework grade improves from near zero to near 100, the level of exam score doesn't change significantly. The spring semester data tell a different story. There is a marked change in level as homework grade improves, suggesting that diligence on homework in some way prepares the student for an exam.

50) Describe the process of root cause analysis and include in your description the tools that it uses.

Answer: Root cause analysis is a process by which organizations brainstorm about possible causes of problems and then, through structured analysis and data-gathering efforts, gradually narrow the focus to a few root causes. The three phases of root cause analysis are the open, narrow and closed phases. The open phase is devoted to brainstorming, where all team members make suggestions, no matter how wild their ideas seem at the time. Teams use a cause-and-effect diagram to organize their thoughts, often around the Five M categories of manpower, methods, materials, machines, measurements. The second phase of analysis is the narrow phase where the brainstormed list is reduced to a manageable number using the Five Whys. In the closed phase of analysis, the team validates the suspected root causes through the analysis of available data. The data might be collected using a check sheet and analyzed with simple graphical tools like a scatter plot, histogram, bar graph, Pareto chart, or a run chart.

Sourcing processes procure goods and services to meet planned or actual demand. The make process transforms product to a finished state to meet planned or actual demand. Delivery processes provide finished goods and services to meet planned or actual demand and include order management, logistics, and distribution activities. Return processes allow the receipt of products that are returned for any reason, whether they are being returned from customer to primary firm or from the firm to one of its suppliers.

11) Describe continuous improvement and business process reengineering and compare their advantages and disadvantages in relation to each other.

Answer: Continuous improvement is the philosophy that small, incremental improvements can add up to significant performance improvements over time. Business process reengineering (BPR) is a procedure that involves the fundamental rethinking and radical redesign of business processes to achieve dramatic organizational improvements in such critical measures of performance as cost, quality, service, and speed. The discrepancy between the two is the magnitude of change in existing processes. Continuous improvement uses the current process as a starting point and allows for an easy transition to the next stage, which is more comfortable for many people and could be sufficient if the existing process is performing well. If a company is suffering due to inadequacy of a process, then continuous improvement may not be fast enough to permit survival in the market. BPR would allow for a quantum leap in process performance as long as all components of an organization are prepared to accept the process changes required.

5) Describe the four quality-related costs and tell how they are related.

Answer: The four quality-related costs are internal failure costs, external failure costs, appraisal costs, and prevention costs. Internal failure costs are caused by defects that occur prior to delivery to the customer, including money spent on repairing or reworking defective products, as well as time wasted on these activities. External failure costs are costs incurred by defects that are not detected until a product or service reaches the customer. Appraisal costs occur when a company assesses its quality levels.

Prevention costs are those costs incurred by an organization to actually prevent defects from occurring to begin with. Classically, we expect that as prevention and appraisal efforts (and costs) rise, that internal and external failure costs should drop.

Diff: 2 Reference: 5.2 Total Cost of Quality Keywords: prevention cost, appraisal cost, external failure costs, internal failure costs AACSB: Application of Knowledge LO: 5.2: Describe the different costs of quality, including internal and external failure, appraisal, and prevention costs.

6) What is the difference between the traditional view of the cost of quality and the total cost of quality perspective?

Answer: The traditional view of quality costs is that as the level of defects is reduced from 100% to 0%, internal and external failure costs fall to zero, and prevention costs rise exponentially. The rationale behind the steeply rising prevention costs is as follows: As the defect level drops, it becomes even harder to find and resolve the remaining quality problems. When we add internal and external failure, prevention, and appraisal costs together, we get a total cost of quality curve. This curve suggests that there is some optimal quality level, Q*, that minimizes the total cost of quality. For defect levels higher than this level, exponentially increasing failure costs cause total quality costs to rise; for defect levels below Q*, increases in prevention costs outstrip decreases in failure costs.

4 .

The new paradigm posits that as a business's processes improved to the point where products and services were defect-free, the cost of appraisal fell. In effect, there was no need to inspect products or services for defects. Furthermore, prevention costs held steady (or even decreased) as managers and employees became more skillful at identifying and resolving problems. With the changing appraisal and prevention cost curves, the total cost of quality curve began to look more like the one below. Note that in this graph, the lowest total cost of quality occurs at the 0% defects level.

38) A cell phone manufacturer inspects the video display on each color phone to verify that the screen can display all colors with the brilliance their customers have come to expect. Each phone is turned on, run through a self-test procedure, and classified as either acceptable or unacceptable based on test performance. The production team takes a sample of 350 phones and finds one with a defective display.

How many additional phones should they sample to establish an average fraction defective for their statistical quality control initiative?

Answer: The initial sample has a fraction defective of 1/350 = 0.002857. The sample size n must be such that Min(np, n(1-p)) = 5. Since p is smaller than 0.5, solving for np = 5 will yield the total number of phones that must be sampled. n(.002857) = 5 n = 5/.002857 = 1750 They have already sampled 350 phones so 1750 - 350 = 1400 phones left to sample.

41) A tailor decides to use Taguchi's quality loss function to analyze his shirt making process. Knowing it to be parabolic in shape and of the form L(y) = k(y - t)2 where t is the target, y is the actual measurement, and k is the process constant, the tailor decides to use a recent customer order to calculate his process parameters. He takes the custom shirt and measures the collar, which was requested to have a 17.5" collar but actually has a 17.75" collar. The customer notices the difference and demands a 50% reduction in the price of the shirt, which cost the tailor $45 to make. Instead of selling the shirt for $175, the tailor will reduce his price to $87.50. What is the tailor's process constant for a silk shirt?

Answer: The tailor is missing out on $87.50 of profit by reducing his price to this extent, so the L(y) = 87.50 = k(y - t)2 where t = 17.50 and y = 17.75.

So, $87.50 = k(17.5 - 17.75)2 k = $1400/inch squared Diff: 3 Reference: 5.4 Statistical Quality Control Keywords: Taguchi's Quality Loss Function AACSB: Analytical Thinking LO: 5.6: Discuss some of the important issues associated with managing quality across the supply chain.

42) Describe the Taguchi quality loss function. What is its shape and what are the implications of this curve?

Answer: The Taguchi quality loss function is a parabola with an x intersection at the target value for the quality characteristic in question. This shape reflects the idea that any deviation from the target value results in some failure cost. These costs start to accrue as soon as there is any deviation from the target and that they grow exponentially as actual results drift even farther away.

11) Define theoretical and rated capacity and name four factors that affect a company's capacity. Indicate how each factor impacts rated capacity.

Answer: Theoretical capacity is the maximum output capability per time period, allowing for no adjustments for preventive maintenance, unplanned downtime, and the like. Rated capacity is the longterm, expected output capability of a resource or system; in other words, it takes into account unplanned downtime, preventive maintenance, and other typical disruptions to planned output. Rated capacity is affected by the number of shifts and lines being operated. As a plant moves from one to two or more shifts or lines, capacity increases. Product variations are another source of variation in capacity. Setups in between products reduce capacity and some products can be made with fewer resources than others, thereby increasing capacity. In general, conformance quality is directly related to rated capacity; as conformance quality increases, capacity increases and vice-versa. Other factors include the capacity of other members of the supply chain, especially if one is functioning as a constraint, and the status of temporary workers and their mix of skills.

12) Describe the three capacity strategies and the advantages of each.

Answer: The three common capacity strategies are lead, lag, and match. Capacity is added in anticipation of demand in a lead capacity strategy. The advantages of this approach are that the organization has adequate capacity to meet all demand, even during high periods of growth and that this capacity can be used to preempt competitors that are planning to expand their own capacity. A lag capacity strategy is realized by adding capacity only after demand has materialized. The authors indicate three clear advantages to this strategy are a reduced risk of overbuilding, greater productivity due to higher utilization levels, and the ability to put off large investments as long as possible. A match capacity strategy strikes a balance between the lead and lag approaches by attempting to meet demand needs exactly, thereby avoiding periods of high over or underutilization.

13) What is a virtual supply chain and how is it different from a traditional supply chain?

Answer: A virtual supply chain is a collection of firms, each of which does only one or two core activities–design, manufacturing, distribution, marketing, and so on. The firms coordinate their activities by using advanced information systems to share critical data. Unlike a traditional supply chain, a virtual supply chain might exist for only a short period. The virtual supply chain might be pulled together during the holiday season to produce and market a new toy, after which it will disappear. The members of the virtual supply chain might even change from one week to the next. However, what virtual supply chains gain in short-term flexibility, they lose in long-term efficiency. As a result, traditional supply chains are more likely to prevail in markets in which long-term relationships or costs are critical.

4) The MBA program at the University of Central Oregon features seven team-taught courses, five credit hours apiece. Each team is composed of somewhat reluctant professors in two distinct disciplines, each of which brings his own perspective to the topic du jour. The program is difficult to coordinate and makes transferring course credit in and out of the program near impossible, so the MBA Redesign Committee spends three years crafting a new program that features twenty-one courses, two credit hours each, that will unfortunately take 18 months to complete compared to the current program's 12 months. The current MBA program brings in about 60 students each semester with the main selling point being the integration between disciplines. It is thought that if the new program can be successfully marketed as an easy fit with other MBA programs in the area, the ability to transfer credits in might attract as many as 70 new students each semester. If the new program is unveiled but the market is still interested in integrated courses, enrollment in the new program might drop to 40 students per semester. If this were the case, the new courses could be scheduled at the same time in the same room and might attract 65 students each semester (with a 0.6 probability) or might attract as few as 50 students with a 0.4 probability. If the existing program is retained but the market is seeking courses that are more transferable, then enrollment in the existing program might fall to 45 new students per semester. If this happens, then the existing courses might be broken in half each night into two classes back to back. Doing so has a .7 probability of increasing new student demand to 65 but has a .3 probability of increasing demand to 55. The MBA Director believes that the market is ready for a less integrated program, and she pegs the probability of that hunch at 0.6, with a 0.4 probability that the market prefers the current integrated program.

26) A major computer manufacturer is interested in establishing a customer service center to handle business for the next decade. They conduct exhaustive research on land and construction costs, utilities, tax breaks, and wages at three sites, Oklahoma City, Austin, and Nashville. Answer these questions using these costs as displayed in the table below.

Costs Fixed ($) Variable ($/unit)

Austin 200,000 7

Nashville 150,000 10

Oklahoma City 300,000 4

Graph the total cost curves and indicate the range of output that is best for each prospective site. What are the assumptions you have made in this analysis?

Answer: The total cost equations are as follows: TCAustin = 200,000 + 7x TCNashville = 150,000 + 10x TCOklahoma City = 300,000 + 4x

16 .

Intersection points of interest are at Nashville and Austin and at Austin and Oklahoma City.

Nashville & Austin 150,000 + 10x = 200,000 + 7x 3x = 50,000 x = 16,666.

Austin & Oklahoma City 200,000 + 7x = 300,000 + 4x 3x = 100,000 x = 33,333.

The best location for each range of output is 0 units through 16,666 units = Nashville 16,667 units through 33,333 units = Austin More than 33,334 units = Oklahoma City This analysis assumes that costs are linear through the entire range of 0 to over 33,333 units.

28) A Seattle entrepreneur must decide on the size of a latte stand to construct. The manager has narrowed the choice down to large or small. If he builds large and experiences low demand he could grin and bear it for a $200 daily profit, lower prices ($225 daily profit), or hire street performers to attract attention ($175 daily profit). If he builds small and experiences high demand he could do nothing ($175 profit per day), stay open longer hours (profit of $225/day), improve processes ($250/day profit), or raise prices ($200/day profit). Building large for high demand has an expected payoff of $250/day and building small for low demand has an expected payoff of $175/day. There is a 0.7 probability of high demand and 0.3 probability of low demand. Sketch a decision tree for this scenario and determine what size stand should be constructed to slake the unquenchable thirst of caffeine addicts.

Answer:

Large Stand = 0.7 × $250 + 0.3 × $225 = $242.50 Small Stand = 0.7 × $250 + 0.3 × $175 = $227.50 At each step choose the highest dollar value. Therefore, choose the large stand.

29) A wise professor crafts a midterm that is beautiful to behold, painful to take, and a chore to grade.

The first exam takes almost an hour and a half to grade (89 minutes and 24.7 seconds to be precise) but the second one takes only seventy-six minutes to complete. Realizing that learning effects are at work, the professor looks at his social calendar and spots an important social engagement at this time on the following day, exactly 24 hours from now. How long will it take to grade the third exam? How long will it take to finish grading exams for the entire class of 30 students?

Answer: The second exam takes 76/89.41167 or 85% of the first, so the learning percentage is 85%.

The third exam will take Tn = T1nb = 89.411 × 3ln(.85)/ln(2) T3 = 89.411 × 3-0.2345 = 89.411 × 0.77298 = 69.10497 minutes All 30 exams will take: T1-n = T1 = 89.4118 minutes × 17.091 = 1528.137 minutes = 25 hours 28 minutes 8.22 seconds Our story does have a happy ending. Since he has already graded two exams in 89.4117 minutes and 76 minutes, only 1362.723 more minutes (22 hours 42 minutes and 43.38 seconds) are needed to grade the last 28 exams, giving him adequate time to grade papers and clean up before the big event.

40) Gerard is choosing between two methods of organizing his bakery. Method one will require a counter person to wait on each customer individually before they proceed to the cashier to pay for their purchases. In this system, customers will arrive at the rate of 8 per hour and can be served by the counter person at the rate of 15 per hour. The cashier will be capable of serving customers at the rate of 20 per hour. For simplification purposes, assume that the arrival rate at the cashier phase is identical to the arrival rate at the first phase and that these waiting lines can be analyzed independently and combined.

Method two will have the two employees wait on customers as they selected their pastries and also collect their money once their selections have been made. Customers still arrive at the rate of 8 per hour but now the total service time (pastry selection and payment collection) takes 5 minutes per customer.

Calculate the average number of customers in the bakery and the average time spent in the bakery for both systems and make your recommendations to Gerard. Assume that service times are exponentially distributed and arrivals follow a Poisson distribution.

Answer: Method one is a two-phase, single server system with an arrival rate into both phases of 8 customers per hour and a service rate at the first phase of 15 customers per hour and the second phase of 20 customers per hour.

The average number of customers in the bakery will be the sum of the customers at the counter and at the cashier.

At the counter step: CSCounter = CWCounter +

=

CSCounter =

= 1.1429 customers

+

=+

At the cashier step: CSCashier = CWCashier +

=

CSCashier =

= 0. customers

+

=+

So the total number in the bakery is 1.1429 + 0.666 = 1.81 customers The average time spent in the bakery will be the sum of the times spent waiting and being served in both phases.

At the counter step: TSCounter = TWCounter +

=

TSCounter =

= 0.1429 hours

+

=+

At the Cashier step: TSCashier = TWCashier +

=

TSCashier =

= 0.0833 hours

+

=+

So the total time in the bakery is 0.1429 + 0.0833 = 0.2262 hours 14 .

Method two is a multiple server system with an arrival rate of 8 customers per hour and a service rate of 12 customers per hour. This analysis requires calculating the probability of zero customers in the system.

P0 =

P0 = 0.5 The average number of customers in the system for method two is:

44) It's a beautiful sunny day after a week of rainy weather and both of the local car washes are busy. One car wash is fully automated, touchless, and can wash a vehicle of any size to a dazzling luster in 5 minutes flat. The other car wash is a fund raiser staffed by eager amateurs that work on one car at a time and can finish it in about 4 minutes (their time is governed by the Poisson distribution). Customer arrivals at both car washes are Poisson distributed with a mean of 10 per hour. How long does it take the average customer to work his way through either system? How many customers are in the systems on average?

Answer: The automatic car wash has an arrival rate of 10 customers per hour and a constant service rate of 12 customers per hour.

23) Why would someone choose to use simulation to analyze a waiting line problem rather than use a formula? What are the advantages and disadvantages of a simulation approach?

Answer: Closed form, analytical expressions are possible for only a few situations in waiting line theory.

Even those circumstances often fail to meet all of the assumptions, for example a true stationary exponential distribution, no reneging, etc., all of the time. For those cases where analytical analysis is not practical, simulation is the best approach.

Simulation models have a number of advantages; they permit off-line evaluation of new processes or process changes, they permit time compression, and what-if analysis.

The disadvantages of simulation are that the simulation model may be oversimplified, that is it fails to accurately capture the nuances of the system to be modeled. Simulation models also generally do not offer optimal solutions and can become costly and time consuming to develop and interpret.

24) What is Monte Carlo simulation and how is it conducted?

Answer: Monte Carlo simulation is a form of simulation modeling called mathematical simulation, where mathematical formulas and statistical processes are used to simulate activities, decisions, and the like. In Monte Carlo simulation, statistical sampling is used to generate outcomes for a large number of trials. The results of these trials are then used to gain insight into the system of interest.

Monte Carlo simulation is used to simulate all types of systems and many types of statistical distributions.

The modeler must map the random numbers to the outcomes of events under study, then generate a stream of numbers that can be interpreted by the mapping so that the events are interpretable. The stream of numbers could be mined from a page turner such as A Million Random Digits with 100000 Normal Deviates by the RAND Corporation or more commonly, from a computer program.

50) What are the four sourcing strategies, how do they work, and what are the advantages of each?

Answer: The main sourcing strategies are single, multiple, dual, and cross sourcing. In single sourcing, the firm depends on a single company for all or nearly all of a product or service, but in multiple sourcing, the firm shares its business across multiple suppliers. In between those ends of the spectrum is dual sourcing, where two suppliers are used for the same purchased product or service, and cross sourcing, where different business units in a single firm use different suppliers for similar parts.

Single sourcing has the advantages of volume leveraging, lower transportation costs, reduced quality variability, and stronger relationships with suppliers. Multiple sourcing creates competition, spreads risk, can help ensure that suppliers do not become complacent, may be required if the purchased volume is too great for one supplier, and may be desired if the buyer wishes to meet obligations to support minority suppliers. Dual sourcing accrues the same advantages as multiple sourcing as does cross sourcing.

51) What are the advantages and disadvantages of insourcing and outsourcing?

Answer: Insourcing gives a company a high degree of control over its operations and can also lower costs but only if a company enjoys the business volume necessary to achieve economies of scale. On the downside, insourcing can be risky because it decreases a firm's strategic flexibility. Making a product or providing a service internally often requires a company to make long-term capacity commitments that cannot be easily reversed. Outsourcing typically increases a firm's flexibility and access to state-of-the-art products and processes. As markets or technologies change, many firms find changing supply chain partners easier than changing internal processes. With outsourcing, less investment is required up front in the resources needed to provide a product or service. The benefits of outsourcing can be significant. Of course, outsourcing has risks. Suppliers might misstate their capabilities: Their process technology might be obsolete, or their performance might not meet the buyer's expectations. In other cases, the supplier might not have the capability to produce the product to the quality level required. Control and coordination are also issues in outsourcing. Buying firms may need to create costly safeguards to regulate the quality, availability, confidentiality, or performance of outsourced goods or services. Coordinating the flow of materials across separate organizations can be a major challenge, especially when time zone differences, language barriers, and even differences in information systems come into play. Companies that outsource also risk losing key skills and technologies that are part of their core competencies.

52) Briefly describe the objective of spend analysis and the general requirements for accomplishing it.

Answer: Spend analysis is the application of quantitative techniques to purchasing data in an effort to better understand spending patterns and identify opportunities for improvement. Spend analysis can be used to answer a wide variety of questions. For example, management might want to know the categories of products or services that make up the bulk of company spending, how much is being spent with various suppliers, and how spending patterns vary across different locations. The primary requirement for accomplishing the analysis is having the necessary data and a means for manipulating it. Because the questions are varied, the analytical tools needed also vary widely. Some companies have software systems used for operations that contain the ability to perform these analyses. Other companies may turn to a spreadsheet package to perform the required analyses.

53) What is sourcing portfolio analysis? Discuss the model and the strategies and tactics associated with each quadrant.

Answer: In portfolio analysis, the products or services to be sourced are assigned to one of four strategic quadrants, based on their relative complexity and/or risk impact to the firm and their value potential. In general, the more money a company spends on a particular good or service, the higher its value potential.

Depending on what quadrant a product or service is assigned to, the buying firm can then identify the most appropriate sourcing strategy, tactics, and actions.

The four quadrants are Routine, Leverage, Bottleneck, and Critical.

The "Routine" Quadrant - Products or services in the routine quadrant are readily available and represent a relatively small portion of a firm's purchasing expenditures. Typical examples include office supplies and cleaning services. The sourcing strategy therefore becomes one of simplifying the acquisition process, thereby lowering the costs associated with purchasing items in this quadrant. Specific actions can include automating the purchasing process, reducing the number of suppliers used, and using electronic data interchange (EDI) or purchase cards to streamline payment.

The "Leverage" Quadrant - Products or services in the leverage quadrant tend to be standardized and readily available, and they represent a significant portion of money spent. The sourcing strategy therefore focuses on leveraging the firm's spending levels to get the most favorable terms possible.

The "Bottleneck" Quadrant - Bottleneck products or services have unique or complex requirements that can be met only by a few potential suppliers. In this case, the primary goal of the sourcing strategy is to not run out; in effect, the goal is to ensure supply continuity. This might involve carrying extra inventory to protect against interruptions in supply or contracting with multiple vendors to reduce supply chain risks.

The "Critical" Quadrant - Like bottleneck items, products or services in the critical quadrant have complex or unique requirements coupled with a limited supply base. The primary difference is that these items can represent a substantial level of expenditure for the sourcing firm. In cases such as this, the sourcing firm will spend considerable time negotiating favorable deals and building partnerships with suppliers, as well as preparing contingency plans in case of an interruption in supply.

54) What is portfolio analysis and how is it accomplished? Provide an example of a purchased product or service that would fall in each area for a university applying portfolio analysis.

Answer: In portfolio analysis, the products or services to be sourced are assigned to one of four strategic quadrants, based on their relative complexity and/or risk impact to the firm and their value potential. In general, the more money a company spends on a particular good or service, the higher its value potential.

Depending on what quadrant a product or service is assigned to, the buying firm can then identify the most appropriate sourcing strategy, tactics, and actions. Examples will vary: Routine products could be housekeeping services. Leverage products could be high expenditure commodity items. Bottleneck products may be IT services and the critical quadrant may include adjunct faculty services for professional programs.

55) Define outsourcing and discuss its advantages and disadvantages.

Answer: Outsourcing is the use of supply chain partners to provide products or services. The advantages of outsourcing are a very low investment risk, improved cash flow, access to state-of-the-art products and services, and high strategic flexibility. The disadvantages of outsourcing include the possibility of choosing a bad supplier, loss of control over the process and core technologies, communication and coordination challenges with the supplier, and an increased risk of supply chain disruptions and CSR risks.

56) The deans' suite hoped to cut costs and decided to perform a total cost analysis on its tequila supplier.

Consumption was currently 10,000 bottles per semester and this was predicted to maintain that level for the next few years. Their current source, Byron's, charged $15.50 per bottle and packed 300 bottles in a crate. The cost to ship the crate was $15. Another potential source of tequilas was Pancho's, who charged $14.75 per bottle but could ship only 100 bottles in a crate and at a higher price, $75. Assume that a partial crate may be purchased. Conduct a total cost analysis and make a recommendation.

Answer: Byron has a product cost of $155,000 and shipping cost of $500 for a total cost of $155,500.

Pancho has a product cost of $147,500 and a shipping cost of $7,500 for a total cost of $155,000 and is therefore the low-cost provider by $500.

Performance Dimension Innovation (W = 0.4) Cost (W = 0.3) Stability (W = 0.2) Speed (W = 0.1)

Company T 4 4 2 3

Company C 4 3 1 5

Company S 2 5 4 5

Company P 5 2 5 2

Answer: Company P has the highest score, 3.8, and would be the supplier of choice ScoreX = ScoreT = 0.4 × 4 + 0.3 × 4 + 0.2 × 2 + 0.1 × 3 = 3.5 ScoreC = 0.4 × 4 + 0.3 × 3 + 0.2 × 1 + 0.1 × 5 = 3.2 ScoreS = 0.4 × 2 + 0.3 × 5 + 0.2 × 4 + 0.1 × 5 = 3.6 ScoreP = 0.4 × 5 + 0.3 × 2 + 0.2 × 5 + 0.1 × 2 = 3.8 Company S is two-tenths behind Company P, and has an abysmal innovation score to thank for this position. If the innovation factor is based on new product or service lines, then Satriale's might request that Company S consider exploring new products more aggressively. Company T is only three-tenths behind Company P, and is slightly behind in the Innovation factor but far behind on the Stability factor.

An increase of 1 point in the stability score raises the overall score of Company T by two tenths, so whatever Company T can do to become more stable should be considered. Satriale's might take a partnership stance, perhaps increase the frequency of meetings in order to help Company T in the stability arena. A single digit increase in Innovation raises a score by four tenths of a point, but Company T has a high score already in this area. It might be easier to raise an extremely low score (Stability) than squeeze another point higher in an area where they are already performing well.

60) The entire plant needs a fresh coat of paint so you, as the operations manager, are charged with securing a painting contract to accomplish this. You locate four painting contractors and ask them for their performance on four criteria. Their responses, along with your minimum standards and the importance you place on each criterion, is shown in the table. Note that strongly positive references are 9 or better on a ten-point scale and positive references are 7 up to 9 on a ten-point scale. Assign scores from 1 to 5 where 1 is terrible and 5 is excellent, for each contractor's performance on each criterion and determine who should be awarded the contract. Write a brief explanation for all the 1s and 5s you assign.

Contractor 1

Cost 20% $22,000

Paint Quality 15% 20 year Lifetime 25 year 20 year 15 year guarantee

Answer: Answers will vary. Contractor 3 cannot meet the paint time criterion, does not have 5 years of experience, and is past the limit on cost. They should either be excluded from bidding or possibly assigned a score of 1 in each of those categories. Contractor 2 is best in cost, time, and paint quality and is tied for best in references and should probably be the highest overall score.

29 .

5) What takes place in each step in the procure-to-pay cycle and which step is most critical?

Answer: Answers may vary on which step is most critical.

In contrast to the strategic sourcing process, the procure-to-pay cycle is decidedly tactical in nature: It involves day-to-day communications and transactions between the buyer and supplier, and it is completed once the goods or services have been received, the supplier has been paid, and the information has been recorded into the database.

The five main steps of the procure-to-pay cycle are: • Ordering — The most common way the ordering step begins is through the release of a purchase order.

A purchase order is simply a document that authorizes a supplier to deliver a product or service and often includes terms and conditions, such as price, delivery, and quality requirements.

• Follow-up and expediting — Someone (typically purchasing or materials personnel) must monitor the status of open purchase orders.

• Receipt and inspection — When the order for a physical good arrives at the buyer's location, it is received and inspected to ensure that the right quantity was shipped and that it was not damaged in transit. If the product or service was provided on time, it will be entered into the company's purchasing transaction system. Physical products delivered by suppliers then become part of the company's working inventory.

• Settlement and payment — Once an item or a service is delivered, the buying firm will issue an authorization for payment to the supplier. Payment is then made through the firm's accounts payable department.

• Records maintenance — After a product or service has been delivered and the supplier paid, a record of critical events associated with the purchase is entered into a supplier performance database.

5) Identify the major trends in supply management and their impact from a strategic perspective.

Answer: The trends in supply management identified in this section are sustainable supply and supply chain disruptions. As more companies become conscious of the importance of being environmentally friendly, environmental performance is becoming an important criterion in selecting suppliers.

Companies want to ensure that suppliers are in compliance with environmental regulations and that they are well positioned to deal with changes in the regulatory environment. Similarly, companies are looking for ways to reduce packaging, promote recycling, and use other strategies designed to reduce cost while being good for the environment.

As supply chains become more extended and firms depend even more on outside companies to provide critical goods and services, many firms are feeling the sting of disruptions to the supply chain. Causes of supply chain disruptions vary from natural disasters to manmade, but in a recent survey of senior executives at Global 1000 companies, the respondents identified supply chain disruptions as the single biggest threat to their companies' revenue streams. The complexity associated with multiple links in the supply chain increases the probability of disruptions.

From a strategic perspective, a company perceived as being "greener" than its competition may win orders that it otherwise wouldn't. Streamlining and outsourcing (or offshoring) allow a company to become more productive by having companies better-suited to produce the outsourced component or service do just that. This carries with it the risk of supply chain disruption, which is deleterious to their competitive position.

Answer: The Council of Supply Chain Management Professionals defines logistics as follows "is that part of supply chain management that plans, implements, and controls the efficient, effective forward and reverse flow and storage of goods, services, and related information between the point of origin and the point of consumption in order to meet customers' requirements." Logistics has a significant impact on a business's cost, flexibility, and delivery performance. Logistics costs account for between 5 and 35 percent of total sales costs and are second only to material costs. Logistics is one component of lead time, so as the time spent in this phase drops, lead time also drops. Lower cost and time result in improved performance for any business.

30) What are the three main categories of logistics information systems? What function does each serve?

Answer: Logistics information systems fall into three major categories: decision support tools, planning systems, and execution systems.

Logistics managers often use decision support tools to design and fine-tune their logistics systems. Such tools help managers choose locations for their warehouses, determine the number of containers or vessels they need, and estimate costs and travel times. Some decision support tools even have simulation and optimization capabilities.

Planning systems help managers with specific activities, such as selecting a carrier for an outgoing shipment or developing a weekly schedule of deliveries. Of course, such activities have been going on for a long time. But with the aid of computer-based planning systems, today's logistics managers can more quickly analyze a wider range of options and identify the delivery schedule or carrier that best suits their needs.

Execution systems are the most detailed level of a logistics information system. As the name implies, execution systems take care of the hundreds of small details associated with logistics activities, ensuring that planned activities take place as expected. They oversee order and shipment management, shipper/receiver management, satellite and bar code tracking, and automated payment and billing systems. Execution systems can also help managers monitor the logistics system and identify problems before they get out of hand.

31) Compare any four transportation modes by volume of goods moved in the United States and apparent strengths and weaknesses.

Answer: The five widely recognized transportation modes are highway, water, air, rail, and pipeline.

Based on Table 8.1 in the text, from a dollar volume of goods moved, highway is over four times the volume of all other modes combined. From a tonnage standpoint, highway has two-thirds of the share, with water and rail each over 10% of share. From a ton-miles perspective, rail has 37% of the business, highway has almost 30% of the market with water and pipeline at 20% or lower. Highway transportation has great flexibility but is neither the fastest nor cheapest option. Water and rail are both highly cost effective for bulky items and are somewhat limited in locations, especially water transportation. Both also suffer from relatively poor delivery reliability and speed. Air is the quickest mode of delivery but also usually the most expensive on a per-pound basis. Pipelines are suitable for fluids and lack flexibility.

32) What is multimodal transportation and why is it an attractive option?

Answer: Multimodal solutions are transportation solutions that seek to exploit the strengths of multiple transportation modes through physical, information, and monetary flows that are as seamless as possible.

Standardized containers that can be quickly moved from a ship or flat railcar to truck with no unloading and reloading of material is the prime example. The result is significant time and cost savings.

33) Choose a major manufacturer and a major retailer and describe two types of warehousing each might use and why they use it.

Answer: Answers will vary depending on examples chosen. A major manufacturer might ship goods to a cross-docking facility that will enable them to parcel out their production to several smaller locations.

They might also use break-bulk warehousing for the same purpose. Both techniques would lower costs by negating the need for long routes served by trucks with very limited variety. A retailer might use cross-docking to take large shipments from many suppliers and send a small portion to each of several retail locations. A retailer might also use a hub and spoke system as part of their distribution chain.

Finally, retailers can use assortment warehousing or spot stock warehousing to serve as a buffer for periods of high demand so they can fill unexpectedly large orders.

27) Compare the advantages and disadvantages of ownership of logistics assets. What factors should be considered when deciding whether to own or outsource the assets needed to execute the logistics function?

Answer: Some factors to consider include the following: Some of the major considerations are reflected in the following questions: Does the firm have the volume needed to justify a private logistics system? Firms with low volumes or sporadic shipping needs (e.g., transport of seasonal produce) are probably better off contracting for those services.

Would owning the logistics system limit the firm's ability to respond to changes in the marketplace or supply chain? Investing in a private fleet of trucks or network of warehouses ties up capital and commits a firm to managing those systems. While that may be fine for firms with stable supply chains, it can present a problem for firms whose markets or supply chain partners are changing rapidly. A manufacturer that wants the flexibility to quickly change from domestic to foreign suppliers probably should not own the trucks and warehouses it uses.

Is logistics a core competency for the firm? Core competencies were defined as organizational strengths or abilities, developed over a long period, that customers find valuable and competitors find difficult or impossible to copy. Many firms have decided that logistics is not one of their core competencies. These firms generally outsource the logistics function to common carriers (also known as public carriers), which handle shipments on a case-by-case basis, or to contract carriers, which enter into long-term agreements with firms. Another choice is third-party logistics providers (3PLs), which are service firms that handle all of the logistics requirements for other companies. Using 3PLs allows companies to focus on their core competencies yet still enjoy access to state-of-the-art logistics capabilities.

Advantages and disadvantages should be linked to the organization's expertise in logistics and their overall strategy and business plan. If the firm has no expertise in the logistics area and time (deliverability) is how they have chosen to win orders in the market, then they are probably best served by outsourcing the function. If they have the expertise or can build it quickly and see delivery speed and flexibility as important, then they might consider owning their own logistics assets.

28) What logistics and warehousing alternatives are most attractive to a company that competes based upon volume and design flexibility? Why? Answer: Volume flexibility, the ability to provide products and deliver services in whatever volume the customer needs, is best served by highway and air transportation and direct shipping or spot stocking.

Spot stocking and direct shipping both help put goods in customers' hands quickly when the distance between the producer and end user would otherwise be very long. Design flexibility, the ability to support design changes that meet unique customer needs is best supported with highway and air and a postponement warehouse. The postponement warehouse permits last minute, light manufacturing alterations to the goods; this delayed differentiation helps achieve the flexibility. The highway and air modes of transport are extremely fast and flexible when used in concert. Assortment warehousing is another alternative that may be attractive.

30) The crowdsourced logistics firm Fed-Ups was developed by two whiz kids that were fed up with paying the exorbitant shipping cost to deliver burritos to their parents' basements. The first month was plagued by a few problems — some participants proved incapable of locating addresses, others had a fear of the outside world, and there was a surprising amount of breakage. Still, they were encouraged as they reviewed the first month's statistics.

Total # Orders Handled # deliveries with breakage # deliveries on time # deliveries to incorrect addresses # deliveries incomplete

340 88 260 48 12

Calculate a maximum and a minimum percentage of perfect orders using the data.

Answer: The difference in the two percentages occurs because one shipment can have multiple errors.

The 260 on-time deliveries mean that there are 340-260=80 deliveries not on-time.

Total # Orders Handled # deliveries with breakage # deliveries not on time # deliveries to incorrect addresses # deliveries incomplete

340 88 80 48 12

If each delivery error occurred with a unique shipment, then 228 shipments contained one error and the percentage of perfect deliveries is 32.94%. If multiple errors can occur per shipment, then there are 8 deliveries with only breakage, 32 late deliveries with breakage, 36 late deliveries with breakage to the wrong address, and 12 deliveries that are incomplete with breakage delivered late to the wrong address.

This is 88 bad deliveries or 252 perfect orders, for a maximum percentage of 74.12%.

Answer: The driving cost is given by: 685 miles × 2 = 1370 miles round trip = 54.8 gallons 54.8 gallons × $1.88/gallon = $103.02 If the plane ticket drops to $103.02 round trip, the cost would be the same.

32) What are the key challenges of implementing a reverse logistics system?

Answer: When incorporating a reverse logistics system into the overall logistics strategy, firms can face a number of challenges. Some of the key ones include: In general, firms have less control over the timing, transportation modes used, and packaging for goods flowing back up the supply chain. This often means reverse logistics systems have to be designed to be more flexible and less cost-efficient than forward-based systems.

Goods can flow back up the supply chain for a variety of reasons. A reverse logistics system must be able to sort and handle these different flows.

Forward logistics systems typically aren't set up to handle reverse logistics. The information systems, material handling systems, and procedures simply aren't suited to the challenges of reverse logistics.

3) What are the laws of forecasting and what are their implications for operations and supply chain managers?

Answer: Forecasts are almost always wrong; forecasts for the near term tend to be more accurate; forecasts for groups of products or services tend to be more accurate; and forecasts are no substitute for calculated values. The first law suggests that operations managers recognize that achieving a close estimate is beneficial. The second law recognizes that the immediate future is more predictable and that techniques to shorten the time horizon for a forecast are in the firm's best interest. The third law accounts for overforecasting and underforecasting errors to cancel each other. Finally, if it is possible to directly calculate values, such as with dependent demand items, this should be done instead of forecasting.

5) Describe three qualitative forecasting techniques and compare their strengths and weaknesses.

Answer: Answers may vary as the text presents five such methods; market surveys, panel consensus forecasting, the Delphi method, the life cycle analogy method, and build-up forecasts. Market surveys are structured questionnaires submitted to potential consumers, often to gauge potential demand. The surveys can be expensive and time consuming but if structured well and properly administered and interpreted, can be very effective.

Panel consensus forecasting is a technique that brings experts together to jointly discuss and develop a forecast. The Delphi method is a technique where experts work individually to develop forecasts that are subsequently shared among the group, after which each participant is allowed to modify his forecast based upon the other group members' ideas. This is an iterative process that is repeated until consensus is reached. Both methods are expensive and time consuming but can be quite accurate if done correctly.

Panel consensus allows for immediate feedback and group synergy. While Delphi lacks immediate feedback and synergy inherent in group discussion, it avoids the problem of a dominant group member.

The life cycle analogy method attempts to identify time frames and demand levels for the introduction, growth, maturity, and decline life cycle stages of a new product or service.

The build-up forecast method sums the specific market forecasts of individuals familiar with those segments.

Answer: Demand Pattern A shows a strong linear trend from 103 up to 207 but Demand Pattern B fluctuates around 169 and (with a standard deviation of 4) is purely random. Adjusted exponential smoothing or linear regression are the only suitable methods for Demand Pattern A. A linear equation of the form Y = 95.98 + 5.82X yields an R squared of 0.99. The randomness in Demand Pattern B is pure noise and therefore not predictable. Moving averages with a large n or exponential smoothing with a low alpha will smooth this randomness but don't truly add much in the way of predictive ability.

15) Multiple regression was used to forecast success in college (GPA) based upon SAT score, high school GPA, and hours spent on-line. Use the regression output shown and comment on the overall fit of the model, the usefulness of each independent variable, and the value to an admissions department of using the model to make admission decisions. What is the model's forecast for an applicant having a high school GPA of 2.5 and an SAT score of 1000 that spends 20 hours a week on-line? What other variables do you feel would make good indicators of college GPA?

Answer: This model was created based on 10 observations so alas, the overall model is not statistically significant nor are any of the independent variables. The r-squared is 0.516, so the model explains over half of the variation in a student's college GPA. The independent variables with the lowest p-values are HS GPA (0.22) and SAT (0.18) so these may be of practical significance but not statistical significance.

Perhaps more data could be collected; with power so low, it's tough to find significance.

For the applicant in question, the model predicts the following: = 0.541 + 0.423 × 2.5 + 0.001 × 1000 + 0.01 × 20 = 2.7985 Not exactly Dean's List material but certainly higher than my undergraduate GPA. Answers may vary on other predictors but possibilities include the number of hours a week spent working and studying, socioeconomic background, parents' education, and many others.

Pellets 0.904 0.817 0.794 0.703 10

Answer: Both models are good predictors of the egg output. Predictably, the model using three predictors has a higher R square(d) and therefore explains more of the variance in day to day egg production. There is something to be said for parsimony, however; if the poultry farmer can track just one input and still do a good job of predicting the day's egg output, then this model has some appeal.

5) What is a collaborative planning, forecasting, and replenishment system and how might it benefit those who choose to use it?

Answer: CPFR is a set of business processes, backed up by information technology, in which supply chain partners agree to mutual business objectives and measures, develop joint sales and operational plans, and collaborate to generate and update sales forecasts and replenishment plans. What distinguishes CPFR from traditional planning and forecasting approaches is the emphasis on collaboration. Experience shows that supply chains are better at meeting demand and managing resources when the partners synchronize their plans and actions. The increased communication among partners means that when demand, promotions, or policies change, managers can adjust jointly managed forecasts and plans immediately, minimizing or even eliminating costly after-the-fact corrections.

Answer: tactical Diff: 2 Reference: 10.1 S&OP in the Planning Cycle Keywords: tactical planning AACSB: Application of Knowledge LO: 10.1: Distinguish among strategic planning, tactical planning, and detailed planning and control.

12) What is the purpose of S&OP and what takes place at the strategic, tactical, and detailed planning and control levels?

Answer: Sales and operations planning is a business process that helps the firm plan and coordinate operations and supply chain decisions over a tactical time horizon. The objective of this is to agree on a single operating plan that allocates critical resources of people, capacity, materials, time and money to most effectively meet the marketplace in a profitable way.

Strategic decisions are made on a long-term basis, much longer than S&OP can be done practically, however the process choice and market decisions made at this level will shape the firm's ability to generate and to meet demand. The tactical level, usually twelve months to two years out, is where workforce, inventory, subcontracting and logistics decisions are made. Planning numbers are aggregated month by month for the purpose of generating a sales and operations plan. Finally, the time period for the detailed planning and control level may be as short as hours or as long as weeks ahead. The planning done at this level may be as simplistic as which job to run next with the capacity that was provided by the tactical level planning.

13) Distinguish between strategic, tactical and detailed planning and control in terms of their ability to adjust capacity, the amount of risk, and the specificity of the plans.

Answer: Strategic planning has the greatest ability to adjust capacity, is the highest risk, and performed at a high level, thus is less concerned with details. Tactical planning has some ability to influence capacity in the short term, is of moderate risk and presents details that are aggregated, perhaps on a monthly basis. Detailed planning and control is very limited in its ability to adjust capacity, is the lowest risk and provides an excruciating level of detail.

14) How can a sales and operations plan be articulated so that all supply chain participants can understand what is needed?

Answer: Finance personnel typically think of business activity in terms of cash flows, financial ratios, and other measures of profitability. Marketing managers concentrate on sales levels and market segments, while operations and supply chain managers tend to focus more on the activities associated with the particular products or services being produced. S&OP includes both levels of output in units but also in dollars; levels of input and options for turning those inputs into outputs are presented in both units and dollars. Thus, finance, marketing and operations workers can see the plan in the units that make the most sense to their function.

32) Describe the differences between level, chase, and mixed production plans. Use the forecast in the table to show the differences by creating a plan of each type. There is no beginning inventory and regular production capacity is 350 units. Overtime costs $10 extra and is limited to 50 units per month.

Subcontracting is limited to 100 units per month and costs $15 per unit. Back orders cost $40 per unit and there is a cost of $5 per month to hold a unit in inventory. There is room for only 100 units in inventory.

Month January February March April

Forecast 250 300 500 350

Answer: Production is held constant in a level production plan while inventory is used to absorb differences between production and the sales forecast. In a chase production plan, production is changed each time period to match the sales forecast. A mixed production plan varies both production and inventory levels in an effort to develop the most cost effective plan.

Production plans will vary.

Total forecasted demand for the planning period is 250 + 300 + 500 + 350 = 1400 This neatly divides by 4 as 350 units per month, exactly equal to capacity. Unfortunately this exceeds the limit on ending inventory.

37) Describe how both top-down and bottom-up planning work and the situations where one approach is superior to the other.

Answer: Top-down planning is an approach to S&OP where a single, aggregated sales forecast drives the planning process. This aggregate sales forecast is translated into resource requirements, effectively moving from sales figures to labor and machine hours and amounts of raw materials, purchased parts or subassemblies. Finally, alternative production plans are generated and compared to see which is best. For top-down planning to work, the mix of products or services must be essentially the same from one time period to the next, or the products or services to be provided must have very similar resource requirements.

Bottom-up planning is an approach to S&OP that is used when the product or service mix is unstable and resource requirements vary greatly across the offerings. Under these conditions, managers will estimate the requirements for each set of products or services separately, translating sales figures into resource requirements just as is done in top-down planning, and then add them up to get an overall picture of the resource requirements.

2. What are cash flows like? Some plans may be profitable at the end of the planning cycle but still include periods in which cash expenses exceed revenues.

3. Do the supply chain partners and the firm itself have the space needed to hold any planned inventories?

4. Does the plan contain significant changes in the workforce? If so, what would be the impact on workforce satisfaction and productivity? Could the HR department handle the additional workload?

5. How flexible is the plan? That is, how easy or difficult would it be to modify the plan as conditions warrant?

8) Your book describes three phases in the implementation of sales and operations planning in an organization. What are the three phases and what takes place in each?

Answer: The three phases are 1) developing the foundation; 2) integrating and streamlining the process; and 3) gaining competitive advantage. Within each phase the following actions take place: Developing the Foundation: In the first phase of implementing S&OP, companies build the managerial support and infrastructure needed to make S&OP a success. Key steps include educating all participants about the benefits of S&OP, identifying the appropriate product or service families to plan around, and establishing the information systems needed to provide accurate planning values.

Integrating and Streamlining the Process: In the second phase of implementation, S&OP becomes part of the organization's normal planning activities. Managers become accustomed to updating the plan on a regular basis, and more importantly, they use the planning results to guide key demand and resource decisions. The sales and operations plan becomes a focal point for cross-functional coordination.

Managers also look for ways to improve the S&OP process further.

Gaining a Competitive Advantage: In the final phase of implementing S&OP, a few companies reach the point where their S&OP process actually becomes a source of competitive advantage – a core competency, if you will. Companies know they have reached this last phase when there is a wellintegrated demand planning process, including the use of forecasting models; continuous improvement is planned and monitored as an integral part of the S&OP process; capital equipment planning can be triggered at any time; what-if analyses are a way of life; and the S&OP database is networked to provide ready access to S&OP data.

8) What are the possibilities for matching capacity to sales and vice versa when doing S&OP in a service environment?

Answer: Inventory cannot be used as a buffer in a pure service environment, so a service sales and operations plan must make sales match capacity or make capacity match sales. Pricing and promotion can be used to bring sales in line with capacity and one technique to do so is yield management, in which prices are regularly adjusted to maximize total profit. In order to make capacity match sales, a service provider can use overtime, a tiered workforce, or offloading. A tiered workforce is one where seasonal workers are hired during peak demand periods and let go during lousy periods of sales. A service provider that offloads work has the customers perform part of the work themselves.

13) Describe any four types of inventory and the drivers that spur their need.

Answer: Answers will vary depending on the types chosen. The inventory types discussed in the text are cycle stock, safety stock, anticipation inventory, hedge inventory, transportation inventory, and smoothing inventory.

Cycle stock is components or products that are received in bulk by a downstream partner, gradually used up, and then replenished again in bulk by the upstream partner. The driver for cycle stock is a mismatch between downstream partner's demand and most efficient production or shipment volumes for upstream partner.

Safety stock is extra inventory that companies hold to protect themselves against uncertainties in either demand or replenishment time. The safety stock driver is uncertainty in supply or demand.

Anticipation inventory is held in anticipation of customer demand and is driven by a mismatch between timing of customer demand and supply chain lead times.

Hedge inventory is a form of inventory buildup to buffer against some event that may not happen and is driven by uncertainty in supply or demand.

Transportation inventory is inventory that is moving from one link in the supply chain to another. This is driven by a mismatch between timing of customer demand and supply chain lead times.

Smoothing inventories are inventories used to smooth out differences between upstream production levels and downstream demand. Smoothing inventories are driven by a mismatch between downstream demand levels and upstream production capacity.

14) Draw a graph that displays both cycle and safety stock for four inventory cycles. Label all elements of the graph and explain the shape and magnitude of each curve.

Answer:

A is the order quantity. B is the level of safety stock in the system. The maximum level of inventory is A+B. C shows the constant downward slope that represents the usage of inventory as time passes. D shows the point in the cycle where the inventory drops to zero and simultaneously the order of quantity A is received.

15) Distinguish between independent demand and dependent demand inventory and provide an example of each from the same company, same product line.

Answer: Independent demand inventory refers to inventory items whose demand levels are beyond a company's complete control. Dependent demand inventory refers to inventory items whose demand levels are tied directly to the company's planned production of another item. Because the required quantities and timing of dependent demand inventory items can be predicted with great accuracy, they are under a company's complete control. Examples will vary, but demand for the Wham-O Company's Hula Hoop is independent while the demand for the beads that make the delightful shoop-shoop sound is dependent on the demand for the Hula Hoop itself.

30) Nothing is too good for my cats, so all their food is custom made at Catastic, who operates a specialty organic food mill in an adjacent state. We need 500 pounds of food per year, distributed evenly throughout the year. It costs $20 shipping and handling to place and receive an order for this delicious food. The cats are fed only on week days, so the 500 pounds per year translates to 2 pounds per day (we go out to restaurants on the weekends). Of course, my cats don't always eat exactly 2 pounds per day, their demand could more precisely be described as an average of 2 pounds and a standard deviation of 0.3 pounds per day. It takes ten days on average to receive an order for food once I place it. It costs $35 to hold a pound of food in inventory for a year and the food costs $850 per pound. It's expensive, yes, but again, nothing is too good for my cats.

32) A small refrigeration shop stocks up on electric motors from a catalog supplier located in the Midwest. The price of the motors varies depending on the quantity purchased; the price breaks are shown in the table. The refrigeration shop knows it will need around 600 motors for the coming season and that it will cost them about $40 to place an order. Storage cost for the motors is $10 each. In previous years they have bought all 600 at once and they are considering doing this again. What order quantity would you advise and how much can they save using your recommendation instead of their one order per year strategy?

14) Three Chums Fish Company buys fresh salmon daily from the fishermen that ply the deep waters of Puget Sound. Salmon are purchased for $2.50 per pound and sold to the public at $8.50 per pound. The salmon are kept fresh by displaying them on ice but at the end of the day, any unsold fish have a noticeable odor and are sold to a nearby chowder stand for $1 per pound.

15) Tickets for the gala Opening Night festivities in Oklahoma City are available for $80 in advance at a couple of area businesses. If you wait until you arrive at the venue, you will pay full face value of $100 per ticket to enjoy the same festivities. If you buy a ticket and don't use it, you can buy $25 worth of chemicals and treat the ticket so that it can be used the following year. You have been taking orders from your friends for a few years and historically demand has been normally distributed with a mean of 50 tickets and a standard deviation of 10. What's the best quantity of tickets to purchase for this year's event?

Answer: The shortage cost is $20 (pay $100 on the day versus $80 beforehand) and the excess cost is just $5 (the $80 ticket can be doctored using $25 of chemicals for a total cost of $105 versus paying $100 the next year). The target service level is 20/25 = 0.8 and the z-score is 0.8416. The order quantity is 50 + 0.8416 * 10 = 58.4.

Another popular answer is that the cost of excess is $25 (for the chemicals) based on the possibility of paying $80 in advance the next year versus $100 the night of the event. In this case the target service level is 0.4444 and the z-score is -0.1397 for an order quantity of 50 - 0.1397 * 10 = 48.6. Since the base price of the ticket is $100, the 58.4 answer is preferred.

16) A local barbecue joint makes one massive batch of potato salad each day. If they run out of this savory side before the end of the day, their last few customers are less than satisfied, but if they make too much, they sell it to the local hog farmer for feed. Every serving costs an equivalent of $0.23 to make, but can be sold for $2.50 to customers and for $0.12 to the hog farmer. The average daily demand is for 400 servings with a standard deviation of 40 servings. How many servings should be made each day? One day the hog farmer cancels the contract – evidently there are some things that even hogs won't eat. With no fallback position, how many servings of potato salad should the barbecue joint make? Discuss the discrepancy between the two numbers.

Answer: If the hog farmer will take the leftovers: CS = $2.50 - 0.23 = $2.27 CE = $0.23 - 0.12 = $0.11 SLT =

Z = 1.683 Q = 400 + 1.683 × 40 = 467.3 If the hog farmer won't take the leftovers: CS = $2.50 - 0.23 = $2.27 CE = $0.23 - 0 = $0.23 SLT =

= 0.908

Z = 1.33 Q = 400 + 1.33 × 40 = 453.1 The discrepancy, about 14 servings, shows that the barbecue joint can't be as aggressive in their production of potato salad each morning. In the new scenario, leftover potato salad is just thrown away, costing the restaurant 23 cents per serving.

30) Explain all of the information that is provided by a master schedule.

Answer: A master schedule is a manufacturing plant's scheduling tool that tracks production output and matches this output to actual sales. A manufacturing plant begins by forecasting demand for their products for the short-term future. The forecast helps provide a rough estimate, but the plant should schedule to produce the amount of each item that is actually ordered by customers, called the booked orders, or the forecast amount, whichever is larger. If the plant already has some finished inventory as they enter a production period, then they do not need to produce as much, only the amount of the actual orders (or forecast) less the beginning inventory. This reduced quantity is the master production schedule amount. Finally, at the end of each production period, the manufacturer will have a number of units in stock. Some of these will have been promised to customers as booked orders. The remaining inventory is available to promise, that is, the next customer placing an order may receive this available to promise inventory since it has not already been committed to another customer.

31) When calculating ending inventory, what does the option presented in the -maximum(F,OB) portion of the equation accomplish? In other words, why don't we always subtract the F value or always subtract the OB value.

Answer: Using the larger of the two values of the forecast and orders booked ensures a conservative estimate for the value of ending inventory. This will trigger production earlier and ensure fewer stockouts and shortages of items. If the lower value were subtracted, the factory may find that a surge in demand exhausts the supply.

35) Describe the scope, inputs, and outputs of sales and operations planning, master scheduling, and MRP. Answer: Sales and operations planning establishes overall production, workforce, and inventory levels and is considered to be tactical capacity planning.

The outputs of sales and operations planning (overall production, workforce, and inventory levels) are the inputs to master scheduling. Master scheduling determines when specific products will be made, when specific customer orders will be filled, and what products/capacities are still available to meet new demand.

The outputs of master scheduling are the inputs to material requirements planning (MRP). MRP calculates the timing and quantities of material orders needed to support the master schedule. It translates the master schedule for final products into detailed material requirements. The output of material requirements planning is production activity control (PAC) and vendor order management.

28) What are three advantages of using an MRP system?

Answer: MRP is directly tied to the master production schedule and indicates the exact timing and quantity of orders for all components. By eliminating a lot of the guesswork associated with the management of dependent demand inventory, MRP simultaneously lowers inventory levels and helps firms meet their master schedule commitments.

MRP allows managers to trace every order for lower-level items through all the levels of the BOM, up to the master production schedule. This logical linkage between higher and lower levels in the BOM is sometimes called the parent/child relationship. If for some reason the supply of a lower-level item is interrupted, a manager can quickly check the BOM to see the impact of the shortage on production.

MRP tells a firm and its suppliers precisely what needs to be made when. This information can be invaluable in scheduling work or shipments, or even in planning budgets and cash flows. In fact, MRP logic is often called the "engine" of planning and control systems. MRP plays a big part in many enterprise resource planning (ERP) systems, described in the supplement.

29) What organizational disciplines are required in order for an organization to successfully run a material requirements planning system?

Answer: For an MRP system to work properly, it must have accurate information. Key data include the master production schedule, the BOM, inventory levels, and planning lead times. If any of this information is inaccurate, components will not be ordered at the right time or in the right quantities. In some cases, the correct components won't be ordered at all. As a result, most firms that want to implement MRP find that they must first ensure accurate planning information. MRP systems must also accommodate uncertainty about a host of factors, including the possibility of variable lead times, shipment quantities and quality levels, and even changes to the quantities in the master production schedule. In general, firms deal with this uncertainty by lengthening the planning lead times or by holding additional units as safety stock. Of course, such buffers increase the amount of inventory in the system. As a result, many firms make a conscious effort to eliminate uncertainty. .

30) Consider the product structure tree shown below:

Assume that the company using this product structure tree has 5 items each at the 0 level, 10 items each at the 1 level and 20 items each at the 2 level. How many units of A, B, and E will the company need to acquire in order to ship an order of 20 X's?

Answer: Working from top to bottom, we need 20 X's and have 5 on hand, so we need to come up with 15 more X's.

15 X's require 30 D's and 45 C's and we have 10 units of both D and C, so our net requirements are 20 D's and 35 C's.

The 20 D's need 40 A's and 60 E's.

The 35 C's need 70 B's and 105 E's and 105 A's Our total gross requirements are 145 A's and 70 B's and 165 E's, but we have 20 each on hand.

Our net requirements at level 2 are 125 A's; 50 B's; and 145 E's.

21) Why are information flows a necessary part of the supply chain?

Answer: Whether we are talking about purchasing or forecasting, master scheduling or project planning, information is an essential part of managing operations and supply chains. The importance of information is reflected in the APICS definition of supply chain: "The global network used to deliver products and services from raw materials to end customers through an engineered flow of information, physical distribution, and cash." In fact, one could argue that neither physical nor monetary flows could take place without information flows. Companies use information to help do everything from handling customers' orders to developing new business strategies. Information is needed to perform basis transactions, plan production, plan, organize and control the conversion process, and coordinate suppliers.

Answer: At the lowest levels, execution and transaction processing needs data to be retrieved and recorded and also to control physical and monetary flows. The routine decision-making level needs a system that can support rule-based decision making. The purpose of an IS at the tactical planning level is to develop plans that coordinate actions of key supply chain areas customers, and suppliers across the tactical time horizon. At the highest level, the strategic supply chain activity needs a system that can help develop long-range strategic plans for meeting the organization's mission.

20) What functions do warehouse management and transportation execution systems perform? What capabilities or services do you think they might possess ten years from now?

Answer: Warehouse management and transportation execution systems initiate and control the movement of materials between supply chain partners. Within a warehouse, for example, sophisticated execution systems tell workers where to store items, where to go to pick them up, and how many to pick.

Similarly, bar-code systems and global positioning systems (GPSs) have dramatically changed the ability of businesses to manage actual movements in the distribution system. Answers as to future capabilities will vary. Amazon has already made a drone delivery, but these deliveries are far from commonplace — perhaps they will be routine in a decade. Perhaps 3-D printing will have evolved to the point where some items can be warehoused and transported in either the traditional sense or printed at any point, including the end user's residence or place of business, at their discretion. I know the latter would be helpful as I continue to craft my army of atomic supermen for world conquest.

Today, there is software available to perform virtually every business function although most of them will not conform exactly to what a company needs. Describe two software tools that can be used for business process analysis and design.

Answer: Two key tools for business process analysis and design are 1) business process modeling tools and 2) business process management system products.

Business process modeling tools are "software tools that aid business teams in the analysis, modeling, and redesign of business processes." BP modeling tools do more than just chart work flows; they allow users to graphically define a process and simulate the performance of the new process to gain insights into how it might work in the real world. BP modeling tools can also help users develop cost estimates based on the sequence of activities in a process and save defined processes in a database so that they can be reused again in other parts of the business.

Business process management systems (BPMS) products are state-of-the-art software tools for developing and implementing business processes. As Harmon puts it, BPMS products are "software tools that allow analysts to model processes and… then automate the execution of the process at run time."

Imagine how this would work: Experts use a BPMS product to develop a process map of how they want a process to work. They then define business rules to manage the flow of work through the process (e.g., "If an order is scheduled to be finished late by X or more days, initiate the defined expedited shipping process"). When the users are satisfied that the new process works the way they want it to, the BPMS product can be used to automatically carry out future business activity, without requiring developers to write new software code.

16) What are the salient features of cloud computing?

Answer: Peter Mell and Timothy Grance of the National Institute of Standards and Technology (NIST) define cloud computing as "a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction." According to Mell and Grance, the cloud model has five essential characteristics: On-demand self-service. Users can automatically access applications and storage space whenever they need them.

Broad network access. Capabilities are available over the network and accessed through standard mechanisms that promote use by a wide range of platforms, including mobile phones, laptops, and PDAs. Resource pooling. The provider's computing resources are pooled to serve multiple consumers, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand.

Rapid elasticity. Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out, and they can be rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service. Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

17) How will cloud computing impact operations and supply chain management?

Answer: First, cloud computing makes it much easier for firms to outsource key portions of their business process information flows (e.g., credit checking, satellite tracking) to outside firms.

Second, broad network access allows individual or computer systems to upload and retrieve information through a wide range of devices virtually anywhere.

In a nutshell, cloud computing will make supply chain information flows faster, more flexible, and cheaper than ever.

21) What is the difference between Lean and kanban?

Answer: Lean is a philosophy of production that emphasizes the minimization of the amount of all the resources (including time) used in the various activities of an enterprise. It involves identifying and eliminating non-value-adding activities in design, production, supply chain management, and dealing with customers. Kanban is more narrowly focused — it is a production control approach that uses cards or containers to control the movement and amount of goods through the supply chain.

22) Provide a definition by description of the Lean philosophy. Where can Lean be deployed?

Answer: Our trusty APICS dictionary indicates.

Lean is a philosophy of production that emphasizes the minimization of the amount of all the resources (including time) used in the various activities of the enterprise. It involves identifying and eliminating non-value-adding activities in design, production, supply chain management, and dealing with the customers. Lean producers employ teams of multiskilled workers at all levels of the organization and use highly flexible, increasingly automated machines to produce volumes of products in potentially enormous variety. It contains a set of principles and practices to reduce cost through the relentless removal of waste and through the simplification of all manufacturing and support processes.

The Lean philosophy has extended beyond just manufacturing to include services and essentially all aspects of supply chain management. Firms following a Lean philosophy often experience remarkable improvements in their productivity (outputs/inputs), inventory levels, and quality. Lean can also be applied outside of the work environment.

Answer: The Lean philosophy places a strong emphasis on reducing raw materials, work in process, and finished goods inventory throughout the system. This is not only because inventory is seen as a form of waste in and of itself, but also because inventory can cover up wasteful business practices. Lowering inventory levels forces firms to address these poor practices.

7) Recent developments in Lean thinking have combined these principles with Six Sigma and with supply chain management. Pick either one of these programs and describe its elements. Then provide an example from current business news of an operation or supply chain that has embraced these principles.

Answer: Examples will vary.

Lean Six Sigma combines the organizational elements and tools of Six Sigma, with Lean's focus on waste reduction. As Paul Mullenhour and Jamie Flinchbaugh put it, "Lean encourages action along a broad front by empowering people at all levels to contribute. This allows organizations to welcome challenges and implement improvement initiatives. Six Sigma brings the discipline of define, measure, analyze, improve and control, as well as the rigor of statistical analysis, to identify a root cause, sustain improvement and provide the solid measurements that create a balanced scorecard."

Some practitioners and researchers have moved beyond Lean production to what can be called Lean supply chain management. In a nutshell, Lean supply chain management seeks to minimize the level of resources required to carry out all supply chain activities. Lean principles are applied to eliminate waste in a firm's sourcing and logistics activities, as well as within the firm's internal operations. But it doesn't end there. The Lean philosophy is applied to all relevant flows — physical, informational, and monetary — and, where possible, to supply chain partners. This means that firms might need to work closely with key partners to eliminate waste within their operations.

33) Describe the movements of parts and kanbans in a two-card kanban system.

Answer: A two-card kanban system has move cards in boxes of raw materials and production cards in boxes of finished goods. When a box of finished goods is pulled by a downstream position (by either a customer or another work center) the production card is removed from the box and placed at the upstream position, thus triggering the need to produce more parts at this position. To do so, the worker at this center must obtain more raw materials, so they pull a box of parts from the upstream position. As they pull this box of parts, they remove the move card and place it in a conspicuous location at the upstream position. This serves as the order to fill that box with more raw materials. Once the box is filled with raw materials, the move card is put back in the box, ready for another cycle. The finished goods container works the same way; once the goods are finished, the production card is replaced and ready for the next iteration.

34) What are the consequences of unstable demand and interrupted flows on a supply chain managed with a Lean philosophy?

Answer: Lean requires that demand be relatively stable and that flows be relatively smooth. If demand rates are unstable and high, then a downstream station might exhaust all of the inventory in their system and be starved for inventory if upstream stations cannot respond quickly enough. If flow is interrupted due to an unforeseen emergency, quality issues, etc., the downstream work station may grind to a halt while issues are worked out at the point of difficulty.

35) Two modules are used to feed the final assembly station on an assembly line. The final assembly station must produce 250 units in an eight-hour day. Each finished unit needs two module A's and 3 module B's. The factory uses a standard sized container that can hold 25 module A's or 35 module B's. It takes 2 hours to fill and move a container of module A's, but only 90 minutes to fill and move a container of module B's. If both module assembly processes have safety factors of 15%, how many containers should be used for each? How many hours of demand will this satisfy?

Answer: The number of containers is governed by this equation. y= yA =

= 5.75 → 6 containers

yB =

= 4.62 → 5 containers

Due to rounding up, there is more inventory in the system than necessary and this will support more hours of production: Hours =

Introduction to Operations & Supply Chain Management, 5e (Bozarth) Chapter 14 Managing Projects 14.1 The Growing Importance of Project Management 1) In what way are projects and typical business activities similar?

A) For most companies, projects and typical business activities can be described as routine.

B) Both projects and typical business activities have a defined ending point at which time they are complete.

C) Projects and routine business activities require significant levels of cross-functional and interorganizational coordination.

Answer: TRUE Diff: 1 Reference: Introduction Keywords: project AACSB: Application of Knowledge LO: 14.1: Explain the difference between routine business activities and projects.

3) Discuss the recent business trends that have increased the attention and interest in project management skills.

Answer: Industry trends have thrusted project management to the forefront. Two trends of particular interest are: a) the faster pace of strategic change and b) the changing role of middle management.

With regards to the pace of strategic change, new product lines must be introduced more often to fight off hungry competitors. Information technology solutions that used to last 10 years are now out of date after five, and customer and supplier networks quickly change, requiring new supply chain solutions. The result of all this is that companies find themselves involved in many more projects with strategic ramifications than they were involved in just a few years ago. As the number of projects increases, the case for improved project management becomes even stronger for a firm.

Project management has also received more attention as the traditional role of middle management has shrunk. Advanced information systems now handle many of the data analysis tasks that middle managers used to perform. At the same time, many companies have taken the authority and responsibility for work outcomes away from middle managers and pushed them down to direct supervisors and workers.

In the project definition phase, planners identify how to accomplish and organize for the work, the key personnel and resources required to support the project, and develop tentative schedules and budgets. In the planning phase, items from the definition phase are revisited and expressed in greater detail. Planners prepare detailed plans that identify activities, time and budget targets, and the resources needed to complete each task. In the fourth phase of the project, the organization actually starts to execute the project plan. In the post-completion phase, the manager or team confirms the final outcome, conducts a post implementation meeting to critique the project and personnel, and reassigns project personnel.

The second phase, the planning phase, is where the company begins to address the feasibility of a product or service.

During the design and development phase the company starts to invest heavily in the development effort and builds and evaluates prototypes. The fourth phase is commercial preparation and consists of ramping up activities associated with the introduction of a new product or service. At this stage, firms start to invest heavily in the operations and supply chain resources needed to support the new product or service. The fifth and final phase of product development is the launch phase. For physical products, this usually means filling up the supply chain with products. For services, it can mean making the service broadly available to the target marketplace.

14) What is the operations and supply chain function responsible for in each of the product development phases?

Answer: The five phases in the development of a new product or service are concept development, planning, design and development, commercial preparation, and launch. In concept development, the operations and supply chain functions scan suppliers for promising technologies and capabilities. In planning, the operations and supply chain functions develop initial cost estimates and identify key supply chain partners. In design and development, the operations and supply chain functions develop detailed process maps of the operations and supply chain flows and test new processes. Commercial preparation calls for the operations and supply chain functions to build pilot units using new operations, train personnel, and verify that supply chain flows work as expected. Finally, in launch, the operations and supply chain functions ramp up volumes and meet targets for quality, cost and other performance goals.

31) What is the Six Sigma approach to new product and process development? What takes place in each step?

Answer: The Six Sigma methodology includes a process called DMADV (Define-Measure-AnalyzeDesign-Verify), which outlines the steps needed to create completely new business processes or products.

As with DMAIC, the DMADV process places a premium on rigorous data analysis, and depends on teams of black belts, green belts, and champions to carry it out.

The five steps of DMADV are: Step 1. Define the project goals and customer deliverables. Since the focus is on a new process or product, the Six Sigma team must properly scope the project to ensure that the effort is carried out in a timely and efficient manner. What products or services do we want to provide and to whom? How will we know when we have completed the project successfully?

Step 2. Measure and determine customer needs and specifications. The second step requires the team to develop a clear picture of what the targeted customers want in terms of quality, delivery, cost or other measures of interest. Market research techniques as well as quality function deployment (QFD), which we describe shortly, are employed here.

Step 3. Analyze the product or process options to meet the customer needs. In this step, the Six Sigma team evaluates how the various options available stack up against the customers' requirements.

Step 4. Design the product or process. Here, the hard work of designing the product or process, takes place.

Step 5. Verify the new product or process. Finally, the team must verify the results. Does the product or process perform as intended? Does it meet the needs of the targeted customers?

32) How does quality function deployment work and what advantages are accrued when it is used?

Answer: Quality function deployment (QFD) is a graphical tool for product design developed in Japan that helps organizations move from vague notions of what customers want to specific engineering and operational requirements. The first QFD matrix translates the voice of the customer into specific product characteristics and shows the relationship between those requirements and characteristics and also among the characteristics. This helps ensure that all customer requirements are addressed by the product or service and that there are no superfluous product characteristics.

36) What are the advantages for a manufacturer of parts standardization and modular architecture and how are they related?

Answer: Parts standardization refers to the planned elimination of superficial, accidental, and deliberate differences between similar parts in the interest of reducing part and supplier proliferation. Modular architecture is product architecture in which each functional element maps into its own physical chunk.

Different chunks perform different functions; the interactions between the chunks are minimal and they are generally well-defined. Modular architecture is essentially standardization in chunks.

37) What is design for the environment (DFE)? Provide examples of products or services that have been developed with this in mind.

Answer: Design for the environment addresses "environmental, safety, and health issues over the product's projected life cycle in the design and development process." The authors cite several examples of Apple's efforts in this area including reduced power usage in sleep mode, reduced packaging and production material requirements, and fewer toxic chemicals used in production and the product itself.

Other examples might include the local utility producing electricity using wind and solar generators, lower consumption of fuel by the Boeing 787, a move by many universities towards disseminating information electronically, e.g., not handing out a paper syllabus on the first day of class, and others.

38) What is value analysis and how is it typically conducted?

Answer: Value analysis (VA) is a process that involves examining all elements of a component, an assembly, an end product, or a service to make sure it fulfills its intended function at the lowest total cost.

The primary objective of value analysis is to increase the value of an item or a service at the lowest cost without sacrificing quality. In equation form, value is the relationship between the function of a product or service and its cost: There are many variations of function and cost that will increase the value of a product or service. The most obvious ways to increase value include increasing the functionality or use of a product or service while holding cost constant, reducing cost while not reducing functionality, and increasing functionality more than cost (e.g., offering a five-year warranty versus a two-year warranty with no price increase raises the value of a product to the customer).

A common approach for implementing value analysis is to create a VA team composed of professionals with knowledge about a product or service. Many functional groups can contribute to the value analysis team, including engineering, marketing, purchasing, production, and key suppliers. Value analysis teams ask a number of questions to determine if opportunities exist for item, product, or service improvement.

Some typical questions include the following: 1. Is the cost of the final product proportionate to its usefulness?

2. Does the product need all its features or internal parts?

3. Is there a better production method to produce the item or product?

4. Can a lower-cost standard part replace a customized part?

5. Are we using the proper tooling, considering the quantities required?

6. Will another dependable supplier provide material, components, or subassemblies for less?

7. Are there equally effective but lower-cost materials available?

8. Are packaging cost reductions possible?

9. Is the item properly classified for shipping purposes to receive the lowest transportation rates?

10. Are design or quality specifications too tight, given customer requirements?

11. If we are making an item now, can we buy it for less (and vice versa)?
