Mistake Proofing / Poka Yoke

Mistake Proofing or in Lean (Japanese) terms is called Poka Yoke which is the process of implementing systems or devices to reduce defects and strive for perfect quality. Poka yoke is an analytical element to Lean thinking. Simplifying processes and reducing errors which are associated waste and costs brings value to operations. The technique to error proofing a product or process is through a Failure Mode and Effects Analysis (FMEA) which roots out potential causes to consistent errors.
