If we trace back the history for the actual incentive to develop a good manufacturing technique, which would be an elementary part to rebuild their economy was the major set back of the Toyota Company after World War II. They wanted to catch up with America as soon as possible in order to save their (Japan’s) automobile industry. Nevertheless the roots are traced back to their strong work ethic rather then sitting idle or wasting time in relaxation. Though the Japanese people were very hard working since the beginning even so, they did not achieve this stage of economic recognition in a day or two. Basically the existing system at that time had many defects in the manufacturing fields. The major defects in the manufacturing industry at that time included the inventory problems, defects in the products, the high cost and delivery delays as well as the large lot production. (Imai (1986)) Nonetheless, only a single product defect is enough to destroy the reputation of the producer, so it was needed to develop a manufacturing system, which was completely, defect free. Therefore, JIT took the initiative to introduce a very strong and solid manufacturing system that was not only defect free from the existing defects of that time but also provided a faster and reliable delivery system in regard to satisfy the needs and demands of the customer. JIT is an integrating production process where the suppliers, manufacturers as well as the customers are inter-related to each other for the successful competition of the JIT manufacturing. The process of JIT does not work on the basis of independence in regard to the stages of manufacturing process. Therefore, the process of the JIT manufacturing needs to complete the following stages as a manufacturing process: Prior to set a JIT manufacturing system, every company needs to define its plan and objectives. However the degree of appropriateness varies from one individual company to another. So planning for JIT is the most important process for setting up a JIT manufacturing system. Furthermore, while planning for JIT, the objectives should be very much clear, as the system needs a complete understanding of its objectives. Once these objectives are set then the process of planning start determining the requirements to meet these well-planned objectives. However to make the goal and objectives successful, it is also important to be equipped to integrate and optimize each and every step of the manufacturing system, to produce the products in time and on demand, to d...
