A bit of Japanese « Yokeru », avoiding. « Poka », errors of carelessness.
Poka Yoke is a system which prevents a defect from being produced or transmitted.
The ‘‘poka yoke’’ makes the transmission of a non-complying product to the next step of the process systematically impossible.
A Poka Yoke could be an hard jig, a device a frame or an electronic device that immediately stops the production of defects.
