What is Poka - Yoke?
Poka yoke is one of the main components of Shingo's Zero Quality Control (ZQC) system — the idea being to produce zero defective products. One way this was achieved is through the use of poka yoke; a bunch of small devices (or ideas) that are used to either detect or prevent defects from occurring in the first place. These poka yoke methods are simple ways to help achieve zero defects. These kind of devices can be implemented on different knid of projects and environments.
