Poka-yoke (ポカヨケ, [poka joke]) is a Japanese term that means "mistake-proofing" or "error prevention". It is also sometimes referred to as a forcing function or a behavior-shaping constraint.

Also called: poka-yoke, fail-safing Mistake proofing, or its Japanese equivalent poka-yoke (pronounced PO-ka yo-KAY), is the use of any automatic device or method that either makes it impossible for an error to occur or makes the error immediately obvious once it has occurred.

Poka-Yoke is a simple methodology for error prevention with the goal of zero defect production. Here we describe how it works!

What is Poka Yoke and How does it Works? Poka Yoke is a Japanese term that means “ mistake-proofing.” It refers to mechanisms used in lean manufacturing processes to help prevent mistakes from occurring, thus ensuring high-quality production and reducing defects.

A combination of source inspection and mistake-proofing devices is the only method to get you to zero defects. Shigeo Shingo shows you how this proven system for reducing errors turns out the highest quality products in the shortest period of time.

What is Poka Yoke? Poka Yoke, pronounced “poh-kah yoh-keh,” is a Japanese term that translates to “mistake-proofing” or “inadvertent error prevention.” It is a fundamental concept within Lean Six Sigma and continuous improvement methodologies, aimed at minimizing human error in processes.
