Plan For Every Part

A detailed plan for each part used in a production process, showing everything relevant to managing the process with no errors or waste. This is a critical tool in the Toyota Production System.

A plan will include the part number, its dimensions, the amount used daily, the precise location of use, the precise location of storage, order frequency, the supplier, pack-out quantity, transit time from the supplier, container size and weight, and any other relevant information. The point is to precisely specify every aspect of the handling and use of every part. (Harris, Harris, and Wilson 2003, pp. 15–22.)
