In implementing a JIT system, the first step would be to rearrange the factory. There's need to move away form batch production functional layout toward one that uses flow lines. In traditional layouts, products usually go through a number of specialized departments that would usually contain a group of similar products. The products have to move over much factory floor before being completed. It is very difficult to determine the progress of production in a batch hence the need to keep detailed accumulation records for WIP in individual batches. The result is high working progress and longer manufacturing costs. What does JIT do? The production process is rearranged by dividing the many different products into families of similar production requirements and routing so that each cell will be like a small assembly line where groups of dissimilar machines are organized into product or component flow line. The machines will be kept close together so that now the products can move easily one by one form one process to another reducing WIP and manufacturing time.
