All About “Poka-Yoke” (Mistake Proofing)

Poka-Yoke was developed by Shigeo Shingo from Toyota Motors as a tool to achieve Zero Defects.

• The process of Zero Defects is also known as “Mistake Proofing” or “Fail-Safe”.

• By taking over repetitive tasks or actions that depend on vigilance or memory, Poka-Yoke can free workers’ time and mind to pursue more value added activities.
