In today s global business world, it is common for a company to control every link in its supply chain. Answer: False (p. 390, difficult, recall) Short Essay Questions 86. What are the typical objectives of managers working in operations? (p. 372) Managers working in operations typically have four related overall objectives. First, they manage activities designed to ensure that the services and products produced for customers have the appropriate quality. Second, they use tools and techniques to ensure that the right quantities of the products and services are produced. Third, they use techniques to ensure that the products and services get to the customer at the right time. Finally, they focus on delivering the first three objectives at the best possible cost. 87. Discuss the term quality and explain how improving quality can lower costs and boost revenues. (pp. 372 373) A popular definition of quality is fitness for use, which is a measure of how well a product or service performs its intended purpose; including how reliable it is and how easy it is to service or repair. This definition applies to products and to services. Higher quality can lower costs through improved efficiency, as well as lower repair and warranty costs. Higher quality can boost revenues by enhancing customer satisfaction, which can lead to repeat business. Moreover, higher quality can lead to positive word of mouth, in which customers recommend the product or service to others. 88. How does the concept of continuous process improvement relate to process reengineering? Identify and discuss the five key elements or steps involved in process reengineering. (p. 374) Continuous process improvement, also known as business process reengineering, refers to both incremental and breakthrough improvements in the way an organization does business. The fundamental premise of process reengineering is that form influences function; that is, the way a process is designed influences its function, which has an important influence on key outcomes. A common approach to process reengineering has five key elements or steps. First, the objective step focuses on determining what a process is supposed to achieve. Second, the design step examines the critical sequences and seeks to maximize the objective and minimize the number, complexity, and time needed to complete the sequences involved 241
in the process. Third, the capabilities step determines the range of abilities needed to execute the design. Fourth, the infrastructure step focuses on the information and other structural elements needed for supporting the design and capabilities needed to meet the objective. Fifth, the metrics step determines the key metrics that help monitor and determine how well the redesign is doing in meeting the objective. 89. Discuss the ABC analysis system of inventory management. (pp. 378 379) ABC analysis provides information about which inventory items require the most attention. In most companies, a small percentage of inventory accounts for the greatest percentage of inventory dollar volume. For this reason, companies are better off putting more effort into controlling and monitoring the higher-dollar-volume items compared with the lower-dollar-volume items. ABC analysis can help companies accomplish this goal by providing a way to classify inventory items into three categories (A, B, and C): A items typically account for the top 15 percent of the firm s dollar volume; B items typically account for the next 35 percent of the firm s dollar volume; and C items typically account for the remaining 50 percent of the firm s dollar volume. 90. What is a just-in-time (JIT) inventory system? (pp. 379 381, AACSB: Information Technology) Just-in-time (JIT) inventory and control systems ensure the timely deliver of a product or service and its related inputs. The objective of JIT is to produce the product or service as needed, using only the materials, equipment, and employee time that will add value to the product or service. The benefits of implementing JIT include the following: (1) reducing inventory levels to only the parts that are needed at the time, thereby lowering the carrying cost of inventory; (2) improving productivity and quality by reducing labor and equipment time; and (3) increasing customer satisfaction by decreasing the time required to make and deliver a product or service. In order to maximize the benefits of JIT, the production of a product or service and its related components must be highly repetitive and standardized. 91. Compare and contrast the following methods of monitoring the progress of projects: Gantt charts and program evaluation and review technique (PERT) and the critical path method (CPM). (p. 381, AACSB: Information Technology) Gantt charts are nonmathematical graphical representations of projects. They are useful for determining what specific activities should be included to complete a project on time. Gantt charts are most often used to monitor projects that have a manageable number of activities (about 25 or fewer). This technique helps ensure that projects (related to production and the production process itself) deliver the designed quality and quantity to the customer, on time. Much larger projects require a more sophisticated technique known as PERT/CPM. The program evaluation and review technique (PERT) and the critical path method (CPM) are useful for scheduling, monitoring, and controlling the timing of large, 242
complex projects, such as the expansion of a freeway system or the construction of a bridge. Due to the complexity of such projects, PERT/CPM software has been developed. Although Gantt charts and PERT/CPM both require a complete list of the specific activities involved and the time estimates for each, PERT/CPM goes one step further in terms of controlling the timing. Specifically, the project manager determines which activities must precede others and which must follow. These relationships help to determine the critical path through the network of activities. This path represents the longest time path for the project and the activities on the path that will delay the entire project, if any one of them is delayed. PERT/CPM software can also help managers reschedule the noncritical activities of a project (i.e., those that can be delayed without causing the entire project to fall behind schedule). The software can even help the process get back on schedule. 92. What is meant by the term productivity? How are productivity measures being used? (p. 382) The simple formula for productivity is as follows: Productivity = Output/Input. Thus, productivity measures how well an organization is using its resources (inputs) to produce goods and services (outputs). A useful productivity measure for a restaurant would be the number of meals served per server. A useful productivity measure for an automobile assembly plant would be the number of labor hours used to produce a car. Productivity measures such as these can be used for two main comparative purposes. First, a firm can use the measures to compare itself to similar firms. Second, a firm can track productivity measures over time to determine a trend. 93. Identify and discuss the major classifications of production processes. (p. 384) There are four major classifications of production processes: continuous flow, assembly line, small batch, and job shop. Continuous flow production is characterized by inputs that are transformed into outputs in an uninterrupted stream. This type of process is common in chemical plants and refineries. Assembly line processes are characterized by a series of workstations at which individual steps in the assembly of a product are performed by workers or machines as the product is moved along. Computers and automobiles are typically produced in this way. Small batch processes are used to produce small batches of products or services. Many university classes are small batch processes, in which a group of students attends a class for a predetermined period of time, during which inputs (knowledge) are added. Job shops are characterized by production processes that focus on the creation of small groups of products with features that are typically different from one job to the next. This category is represented by high-end tailors that produce custom-made suits for customers. 94. Discuss the nature of the relationship between customers and suppliers along a supply chain. (p. 389) There is an inherent tension between customers and suppliers along a supply chain. On the one hand, there are incentives for customers to partner with suppliers. In other 243
words, the tighter a customer is integrated with its suppliers and the more it depends on them, the more its operations managers need to work closely with the suppliers, build trust, and take a long-term perspective. On the other hand, Internet-based technologies have lowered the entry barriers for new suppliers and lowered the costs of switching to new suppliers. Therefore, operations managers may not want to get too close to their current suppliers, just in case better suppliers may come along. In addition, there is always the threat of suppliers forming their own supply chain in order to compete with their former customers. Thus, there is a dynamic tension between taking a transactional or adversarial orientation and a partnership orientation. 95. What is a reverse supply chain? (p. 390) Increasingly, operations managers have been focusing on the reverse supply chain. Their focus relates to the activities needed to retrieve a used product from a customer and either reuse it or dispose of it. Reverse supply chain managers have to focus on at least five key activities: (1) acquiring the used products, (2) managing the reverse logistics to get the products to the company, (3) inspecting the product, (4) determining the disposition of the product (destruction or reuse), and (5) distributing and selling refurbished products. Note: The remaining questions in this section will be based on the following scenario: ABC Office Products sells copy machines and other office equipment. Business has been good, and ABC has expanded its operations in New Orleans, LA, where it provides sales and service to over 7,500 customers. ABC receives numerous calls every day for repairs and supplies. All calls are answered by customer service representatives and then routed to the appropriate departments. During the final quarter of last year, customers began to complain about how long it took to get their phone calls answered by customer service, and how long they had to wait on hold before being helped by the repair and supply departments. This year, customer complaints have increased. Collin Stone, the owner of the company, realizes that this is a serious problem since ABC s reputation has been built on efficient customer service. Mr. Stone has authorized Sam Nguyen, the manager of the customer service department, to study this problem and report to him ASAP. 96. How does the concept of quality apply to this scenario? (p. 372) The concept of quality is often defined as fitness for use, which is a measure of how well a product or service performs its intended purpose, including how reliable it is and how easy it is to service or repair when it does break down. Traditionally, this definition has been applied to products; however, the elements can also apply to services. In this scenario, the quality of ABC s service to customers is breaking down (1) during the time when they first contact the company and (2) during the time they have to wait to order supplies or request repairs. These issues must be remedied, or the quality of the customerservice experience will continue to suffer. 244
97. Could the philosophy of Total Quality Management (TQM) be applied in this scenario? (p. 373) The TQM philosophy involves a commitment from all levels of employees to strive to make improvements and satisfy customers, on an ongoing basis. TQM emphasizes quality at the source ; that is, quality inspection at all stages of production or service output. Quality at the source involves the use of quantitative techniques, such as statistical process control, and qualitative techniques, such as employee empowerment. Statistical process control (SPC) at ABC would provide an objective tool to analyze how customer calls for repairs and supplies are being handled. Although ABC should have a goal of 100 percent customer satisfaction, slight deviations cannot be eliminated. Thus, ABC should seek to minimize the occurrence of deviations. Managers could use a process control chart to track how phone calls for customer service are being handled, and identify unacceptable deviations. The results could be used to determine the causes of good or poor performance. Then, these causes can be reinforced or corrected, as needed, via the process of continuous improvement. Employee empowerment will be critical to improving how customers calls for repairs or supplies are handled at ABC. Empowered employees will take pride in and responsibility for their individual performance, as well as the performance of the entire organization. Since the employees from the customer service, repair, and supply departments are experts in their areas, they should be able to provide valuable input on how to improve the quality of the customer-service experience, right at the source. In addition to the quantitative and qualitative elements described above, top managers at ABC must be committed to the TQM philosophy. They will need to communicate the TQM vision and provide the strong leadership needed to focus on the needs of customers and implement the changes required for TQM to succeed. 98. Could continuous process improvement be used in this scenario? (p. 374) The term continuous process improvement refers to incremental and break-through improvements in the way an organization does business. Underlying this concept is the idea that the way a process is designed influences how well or poorly it functions, which in turn has an important influence on key outcomes. The following key elements could be applied to this scenario. (1) Objective: reducing customer complaints by improving the quality of how their calls for service and supplies are handled. (2) Design: examining the way that phone calls are handled, in order to maximize the objective while minimizing the complexity of the process. (3) Capabilities: determining the capabilities needed to improve the process of handling customers calls. (4) Infrastructure: focusing on the information and other elements needed to support the design and capabilities needed to meet the objective. (5) Metrics: setting key metrics to monitor process improvements and determine how well the redesign is doing in meeting the objectives. 245
99. Could capacity planning play a role in this scenario? (p. 376) While rendering high-quality customer service will be important to ABC, their customers will also care about the right quantity. Managers at ABC can use capacity planning to determine how much service the company should be able to render. Although ABC would like to operate at maximum capacity (design capacity) at all times, doing so is not realistic. Rather than running at its design capacity (maximum capacity under ideal conditions), ABC should seek to run at its effective capacity instead. The effective capacity is the percent of design capacity actually expected, and it can be expressed as a simple formula: Effective Capacity = Expected Capacity/Design Capacity. 100. What role could timing play in this scenario? (p. 379) Even if management at ABC takes action to produce the right quantity and quality of customer service, they still must ensure that the timing and delivery of customer services meet the needs and expectations of customers. Not providing service to customers when they want it can cost ABC repair and supply revenues, as well as word-of-mouth and repeat business. 246
