What is the main purpose of Poka Yoke?

Poka Yoke, a concept originating from lean manufacturing, focuses primarily on preventing errors in processes. The term itself translates to "mistake-proofing." Its main purpose is to design systems and processes that help avoid mistakes or defects by eliminating the potential for human error. This is accomplished through various means, such as automatic mechanisms, visual aids, and simplified procedures, ensuring that tasks are performed correctly the first time.

By creating safeguards within processes, Poka Yoke ultimately aims to enhance the quality of the output, reduce rework, and ensure that errors are caught before they reach the customer. While improving workflow, facilitating communication, and enhancing productivity can all be benefits of implementing Poka Yoke, its core objective is specifically to mistake-proof processes, underscoring the importance of quality management in operational efficiency.
