What do Jidoka and Poka Yoke mean?

Jidoka can be used to avoid errors, while Poka Yoke can be used to detect them. Both methods in combination increase efficiency and production.

• Jidoka: If technical problems occur, a machine or system switches itself off. Monitoring systems, for example using sensors or detectors, are used for this purpose. In the event of production and machine faults, a machine is thus able to detect these independently, so to speak. This results in an automatic shutdown, which is why Jidoka is also referred to as “autonomation” (a combination of “autonomy” and “automation”).

• Poka Yoke: A zero-defect system that eliminates errors as a preventive measure. Work steps that have to be repeated frequently are susceptible to carelessness creeping in. The zero-defect principle is the basis of fully automated processes in production and data management or data consolidation.
