Hello Class JIT stands for “Just-in-time” which is an inventory control strategy where raw materials are ordered when needed. This strategy is used to lower holding costs and boost inventory turnover. Companies that use JIT receive raw materials and products as needed, which reduces waste and improves operating efficiency. The JIT strategy is successful with consistent manufacturing, a reliable supply chain, and reliable equipment which doesn’t fail. SMED stands for “Single Minute Exchange of Dies” and is a lean production method. This technique reduces the turnover time of their equipment. This technique does not mean that the changeovers should only take one minute but that every changeover should be less than 10 minutes, meaning a single digit. The technique reduces the time needed to turn the equipment over and simplifies the process. This is done by eliminating any extra steps. The steps are Identifying the pilot area, identifying elements, separate external elements, converting internal elements to external ones, and streamlining the remaining elements. Toyota was the first company that successfully implemented the JIT strategy. The way that it works for Toyota is that vehicles are produced based on the orders that are received from the dealers. The company's supply chain is set up where only the parts that are needed to manufacture the orders are received on time. This allows Toyota to keep a low inventory of vehicle parts since manufacturing and transportation of parts happen simultaneously.( Parashar, J., & Parashar, J, 2016) Looking at SMED it would be a benefit to any manufacturer to use this technique. The technique lowers production time, which allows the company to produce more in the same amount of time and therefore increases profits. Toyota was able to reduce changeover times from hours to 15 minutes and then down to three minutes over the years. (Roser, C., & Roser, C,2021) References Keller, P. A., & Pyzdek, T. (2018b).
