POKA-YOKE

Poka-yoke -- Japanese for “oops proofing.” A method of designing processes, either production or administrative, which will by their nature prevent errors. This may involve designing fixtures, which will not accept a defective part or something as simple as having a credit memo a different color than debit memo. It requires that thought be put into the design of any system to anticipate what can go wrong and build in measures to prevent them. Poka-yoke supports the concept of quality at the source.
