How important is managing operations to the competitiveness of a small business? Why? The customer’s idea of quality is the one that counts. The seller’s idea that a quality rating of 8 is satisfactory is irrelevant if the buyer expects a quality rating of 9.5. Repeat business depends on the customer’s evaluation of the product and/or service. Does the product or service meet or exceed the customer’s expectations? Even though the producer (seller) recognizes that the customer is the ultimate arbiter, that producer may not correctly understand the customer’s expectations. Efforts should be made not only to recognize the importance of meeting customer expectations but also to discover the nature of those expectations and the extent to which they are being met. 2. What are some distinctive features of the operations process in service firms? Total quality management (TQM) refers to a people-focused philosophy of management that stresses the need to continue to increase customer satisfaction and lower cost. Quality becomes a major goal of the business. It entails the management changes needed to encourage and measure quality in both design and processes, and in both raw materials and employee performance. The ultimate goal of TQM is to have zero defects and to strive for ever more responsive customer service. Several methods are used to produce quality, including quality circles, inspection, and statistical quality control techniques. 3. Customer demand for services is generally not uniform during a day, week, or other period of time. What strategies can be used by service businesses to better match a company’s capacity to perform services to customers’ demand for those services? Some firms, such as beauty shops, use appointment systems. Others (for example, dry cleaners) take customers’ orders and work the orders into their own production schedules. Still other firms, such as theaters, maintain a fixed schedule of operation and tolerate fluctuating demand. Restaurants use incentives such as “early bird specials” to promote greater use of services during off-peak hours. 4. What are the major features of the just-in-time inventory system? Is it applicable to small companies? Be prepared to defend your answer. Traditional methods will not usually suffice in a small manufacturing plant. Studies have been made of 100 percent reinspections conducted in many plants; in every case, further defectives were found in lots that were reinspected. In one such case, nine reinspections were required before the lot was found to be free of defectives. 228 © 2012 Cengage Learning. All Rights Reserved. May not be copied, scanned, or duplicated or posted to a publicly accessible website, in whole or in part. Chapter 21 Managing Operations Moreover, an inspector may measure and identify good items and defectives correctly but still deposit them in the wrong container (good items in the rework barrel and vice versa). One cause of such inaccuracy is the monotony created by repetition of movements, measurements, and evaluation, such as the inspection of 1,000 to 5,000 items per lot. 5. Why is the customer focus of quality management so important in a small firm? Why can be done to ensure that the quality of a small venture’s products or services remains high? The operations process in service firms must deal with distinctive features such as measuring an intangible service e.g. the quality of a shampoo. In general, it is harder to measure quality of a service than the quality of a physical object. Also the process is often complicated by the interaction between the customer and the process. A dentist, for example, works on the customer. Scheduling is often more complicated because of the need to relate to the customer’s schedule. 6. How important is effective purchasing to a small business? Can the ownermanager of a small firm safely delegate purchasing authority to a subordinate? Explain. Some firms, such as beauty shops, use appointment systems. Others (for example, dry cleaners) take customers’ orders and work the orders into their own production schedules. Still other firms, such as theaters, maintain a fixed schedule of operation and tolerate fluctuating demand. Restaurants use incentives such as “early bird specials” to promote greater use of services during off-peak hours. 7. Under what conditions should a small manufacturer either make component parts or buy them from others? A small firm should make component parts if doing so (1) uses excess plant capacity, (2) increases supply reliability, (3) protects proprietary technology, (4) reduces costs, (5) facilitates production coordination, and/or (6) yields higher quality components that are otherwise available. The firm should buy these components if (1) outside suppliers can provide cheaper inputs, (2) doing so will not require additional resources, (3) this prevents the diffusion of managerial expertise, (4) it provides increased flexibility, (5) this strategy transfers the risk of obsolescence to an outside party, and/or (6) it shifts obsolescence risk to outsiders. 8. What are the relative merits of inspection approaches and poka-yoke to quality assurance in a small company? Reengineering is an attempt to increase productivity by going beyond minor, incremental changes in production systems to make more basic or fundamental structural changes. It asks questions about the nature of the business and ways in © 2012 Cengage Learning. All Rights Reserved.

Reengineering, if carried out correctly, avoids the error of making tiny improvements in inherently defective systems. An underlying assumption is that an operations system designed twenty years ago may no longer be the best operations system. 9. What steps can a company take to build good relationships with suppliers? Can you think of any ethical issues that should be taken into account when deciding how to interact with suppliers? Productivity is concerned not only with the volume of output but also with the quality of the products. Productivity is improved, therefore, as output is increased and also as quality is improved. Quality improvement prevents the reworking of defective items and minimizes customer dissatisfaction and costs associated with warranties. 10. Explain the meaning of the terms lean production and synchronous management. How are these relevant to operations in a small company? Purchasing would be a vital function if, for example, the firm faces a relatively high cost of goods sold (i.e., if this expense has a significant effect on gross margins). Other concerns, such as the potential impact on input quality, should also be considered. Whether the owner-manager can safely delegate purchasing authority to a subordinate depends on the capability and training of the subordinate and the importance of inputs to be purchased. COMMENTS ON CHAPTER “YOU MAKE THE CALL” SITUATIONS Situation 1 1. Is the writer of the article correct in believing that quality levels not are generally higher and that quality differences among businesses are minimal? As a sweeping generalization, this may well be true. In the last two or three decades, attention to quality has increased dramatically, and this has truly yielded significant results. However, the owner needs to realize that there may be vast differences from industry to industry. Also, the quality of pizza available in local markets varies widely as local pizza enthusiasts can testify. Therefore, the writer is probably right, in general, but might be wrong in this situation. 2. What are the benefits and drawbacks of placing the firm's primary emphasis on minimizing customer waiting time? Benefits would include: 230 © 2012 Cengage Learning. All Rights Reserved. May not be copied, scanned, or duplicated or posted to a publicly accessible website, in whole or in part. Chapter 21 Managing Operations (a) Directing attention to an issue of real importance to most customers (b) Possibly gaining an advantage over competitors on this feature (c) Finding weaknesses in present delivery systems Drawbacks would include: (a) Overlooking quality problems that may exist (b) Possibly creating quality problems by focusing on speed (c) Giving insufficient thought to still other aspects of operations that may need improvement (that is, by trying to solve the wrong problem) (d) 3. If you were advising the owner, what would you recommend? This question allows for individual answers that should be supported by sound reasoning. Ideally, there should be clear recognition of the great importance of quality, the present level of quality, how the owner can discern this level (e.g., through comparisons with competitors), and how this level might be measured. Getting a bad pizza fast is not a good outcome! Also, it is desirable to give some thought to the competition that typically exists between quality and speed and consider ways to minimize that conflict. We should note that speed is measured more easily than is quality. Situation 2 1. What are the ethical issues raised by Tandy’s payment practices? The ethical implications here are a bit nebulous. Clearly he is violating the terms of the purchase agreement, however, the onus is on the supplier to enforce the payment terms. Tandy has a moral obligation to adhere to the 30 day payment terms however, paying 10-15 days beyond this is not an egregious act. To default on the amount owed would be an egregious act. 2. What impact, if any, might these practices have on the firm’s supplier relationships? How serious would this impact be? Building good relationships with suppliers is essential for the success of an small business. Tandy could jeopardize his working relationship with these suppliers and they could decide to stop selling to him if he doesn’t pay his bills on time. Tandy needs to implement a policy of fair play and cultivate a good relationship with his suppliers. He can do this by: Paying bills promptly Giving sales representatives a timely and courteous hearing. Minimizing abrupt cancelation of orders © 2012 Cengage Learning. All Rights Reserved.

What changes in company culture, employee behavior, or relationships with other business partners may result from Tandy’s practices? Others may lose respect for him and / or not want to do business with him. If Tandy proves to make promises that he can’t keep, he will lose credibility with this employees, suppliers and customers. Suppliers may talk to other suppliers and Tandy may be in a position where he can’t get competitive bids on products, thereby increasing his cost structure and lowering his profits. An extreme and consistent trend of this behavior could result in Tandy’s going out of business. Situation 3 1. What can be done to improve capacity? An examination should take place to look for constraints or bottlenecks during peak times. If these are found to exist and then changed, this would solve the problem. 2. What can be done to improve efficiency? The bottlenecks and/or constraints that might be discovered could also have an impact on efficiency. Changing these could lead to more efficient operations at the different stations. Training could have an impact on efficiency as well. 3. What can be done to improve the filtering process? One possibility to handle the filtering process is to have an employee check with the customers who are standing in line to take order before they reach the counter. This might forewarn of shortages before the customer reaches the station and allow employees to obtain items/materials by the time the customers get to the station. 4. What could be done at a store level to improve the performance of the business? 232 © 2012 Cengage Learning. All Rights Reserved. May not be copied, scanned, or duplicated or posted to a publicly accessible website, in whole or in part. Chapter 21 Managing Operations There are several options. Among them is to hire part time employees for peak periods and develop training programs to allow all employees to be better prepared for the needs of customers. A measure for bottlenecks and constraints must be established to allow the business to meet the needs of customers at a rapid pace. Establishing the cashier station away from the barista station and/or the drive-through station could allow customers to establish separate lines that don’t interfere with each other. Providing designated locations for the different lines could also create help with improving the performance. SUGGESTED SOLUTION TO CASE 21: RIVER POOLS & SPAS 1. Review the history of the operations of River Pools & Spas, from start to success, to scaling back. How was the company affected by scaling back? What changes made it more competitive? 2005 River Pools & Spas have over 75 in-ground pool installations, 20 fulltime employees, and a new 10,000 square foot showroom/warehouse 2006 they installed 80 in-ground pools in a declining economy 2007 they installed 88 in-ground pools in a declining economy 2010 the economy crashed. Sales were down and they had too many employees. They are now down to six employees (a bookkeeper, office manager, two production managers and two installation crews). To adjust for this downturn the company had to close up their brick-and mortar showroom and moved everything to the Web. They are now the world-leader website for fiberglass pools and get requests from Utah to Costa Rica where before they only services the Maryland/Virginia region. Moving to the Web broadened their customer base and has allowed them to tap customer markets that before they never would have considered. Additionally, by dramatically reducing their fixed overhead costs, they have increased their competitiveness in the market. 2. Describe how River Pools & Spas’ customer focus affects the business. What can the owners do to ensure that the quality of their products and services remains high? River Pools and Spas embodies the essential features of successful quality management. The company is customer driven, with a commitment to the organization and a culture of continue improvement. The three pillars of quality success. The customer’s needs and wants are the core drivers for this business. Management leads but the entire organization participates. The company is also much more than a one-off effort. It focuses on a culture of continues improvement. © 2012 Cengage Learning. All Rights Reserved.

Having direct contact with customers can serve as the eyes and ears of the business in evaluating existing quality levels and customer needs. The company should also work hard to involve and empower the customer in efforts to improve quality. To accomplish this they can utilize surveys, interviews, or observation techniques. The company can also utilize control charts to manage the quality of their products (eg. Scatter diagrams, Pareto charts, flow charts, etc.) 3. Does this company use a synchronous management approach? Synchronous management is an approach that recognizes the interdependence of assets and activities and manages them to optimize the entire firm’s performance. The approach presumes that the goal of the organization, and the definition of performance that flows from it, is known and influences all decision making. It requires an understanding of how a shift in one area of operations can affect the rest of the organization- that is- it provides insight regarding interrelationships between assets, changes in activities, and achievement of the firm’s goals. One can infer from the quick responsiveness, high quality and strong market share that this company is functioning in a synchronous, harmonious way. 234 © 2012 Cengage Learning. All Rights Reserved.
