Mistake-Proofing

Mistake-proofing, also known as poka-yoke, is a method used in processes to prevent errors before they happen or to easily detect them if they do. It involves designing systems, tools, or procedures that make mistakes difficult or impossible to occur, thereby improving quality and safety. For example, a device that only fits in one correct way or a checklist that alerts you to missing steps are mistake-proofing measures. The goal is to enhance reliability, reduce having to fix errors later, and ensure consistent, high-quality outcomes.
