Howev er, because they can produce burgers in a record time, they don't hav e to worry about their pre-made burger inv entories running out in the middle of an ex ceptionally busy shift. Wal-Mart accomplishes this by demanding it, Dell by working with suppliers, and McDonald's by standardizing production. In order to accomplish the tasks of shortening lead times and reducing their v ariances, a considerable amount of work needs to be done with suppliers/internal operations. For some firms this is worth the trouble, for others, it is not. Conclusiv ely , there are two major parts to JIT inv entory operations: lowering the ratio between ordering costs and holding costs and shortening lead times.

It is therefore, essential for various tools to be used in analyzing the information environment and the physical product. One of the most useful tools is referred to as process activity mapping. The major role of this tool is to identify productivity opportunities and lead time for both information flows and physical product flows (Lai,
