A Case Study on Just in Time (JIT)

Productivity improvement is the one of the basic need of every manufacturing industry, so that Just in Time (JIT) is one of the quality tools that are help to improve the productivity. Just in Time (JIT) has been very popular strategy partly because of its success in Japanese manufacturing, Automobile industries. Analysis of wastages is one of the needs of every industry, so we are using the value mapping analysis to check each value-added and non-value-added activity. Just in Time (JIT) is a system that focuses on inventory control, set up time reduction, waste reduction and continuous improvement to achieve operational excellence. In this paper a single case study is doing in the manufacturing company (Towers making). The main objective of this paper to checking each and every activity to achieve the manufacturing time is less than customer order time. Take a pad and pencil and go out on the shop floor. Pick a product and follow it through the entire manufacturing process from raw materials to shipping. Note every activity performed on the product. Do not get a routing slip to see how the process is supposed to go, but accurately record the process including delays, transportation, inspection, storage, etc. After recording time to calculate Available operating time, performance factor, quality rate and overall equipment efficiency. After calculating overall equipment efficiency to compare with international standard and get suggestions to the case company.
