Tom Mast is a lathe operator for a company that manufactures precision metal products. The the is the first step in the manufacturing process. Jobs begin at the lathe based on customer orders that call for specific numbers of pieces to be shipped. When an order is started, Tom generates the number of pieces ordered, plus a \(10 \%\) cushion. According to Tom, "This overrun is necessary to allow for errors and scrap in subsequent manufacturing steps." Since production begins based on customer demand, is the company using a JIT system? How could principles of TQM and JIT help the company?
