poka-yoke

It also means that work must be rigorously standardized by the work team, not by some remote industrial engineering group and that employees and machines must be taught to monitor their own work through a series of techniques commonly called poka-yoke, or mistake-proofing, which make it impossible for even one defective part to be sent ahead to the next step.7

Then they would mistake-proof – or apply poka-yoke – to the resin dye rack.

A simple example of a poka-yoke is installing photo cells across the opening of each parts bin at a workstation.

Scheduling equivalents of poka-yoke devices have been developed to make sure all mistakes are caught.

In posing this question, they were not asking about specific techniques—how to organize teams, how to use Quality Function Deployment in product development, or how to poka-yoke mistake-proof production processes.

The kits were themselves a poka-yoke device because the parts were placed on the cart in their exact assembly sequence.

In this way Toyota has installed a poka-yoke device in the ordering system to filter out noise.
