Chapter 7: Just-in-Time and Lean Systems Overview This chapter examines the core beliefs of just-in-time systems (JIT). The goal of reducing waste is important in JIT. JIT uses a pull system, which is different than the push system. The key elements of JIT are described. The critical role of TQM in JIT is explained. The role of the employees in JIT is explained. Finally, we gain an understanding of the impact of JIT on all functional areas within both service and manufacturing organizations. Answers to Discussion Questions in Textbook 1. Describe the core beliefs of the JIT philosophy. The core beliefs of JIT are the elimination of waste, the ability of the employees to see the “big picture,” simple solutions, continuous improvement, visibility and flexibility. JIT strives to produce the right products at the right time in the right quantities. Continuous improvement and flexibility are important beliefs that help us achieve this goal. 2. Identify the three major elements of JIT. The three major elements of JIT are just-in-time manufacturing, total quality management (TQM) and respect for people. 3. Explain how JIT manufacturing works and its key elements. JIT manufacturing focuses on value-added processes in order to produce high volumes of high quality, low cost products that meet the customer needs. Its key elements are the pull system, kanban production, small lot sizes, short setup times, uniform plant loading, flexible resources and a streamlined layout. 4. Find an example of successful JIT manufacturing. Toyota is a company that has successfully used JIT. It is the company that developed JIT. JIT has resulted in short lead times, high quality, low costs and flexible production. 5. Explain the importance of total quality management in JIT. TQM is critical in JIT since poor quality would cause us to not deliver the right products at the right time in the right quantities. Poor quality would cause us to have to either spent time fixing the product or to scrap it if it can not be fixed.

6. Find an example of successful TQM implementation. Motorola, a winner of the Malcolm Baldrige National Quality Award, has successfully implemented TQM. Motorola is also known for focusing on achieving six sigma quality, which translates into about 3 defective parts per million. 7. Explain the importance of respect for people in JIT. Respect for people is important in JIT because everyone must be involved in managing and improving production. The employees must work together effectively in order to successfully implement JIT. 8.
