“Poka-yoke” is a Japanese term that means “mistake-proofing” or “error-proofing.” It’s a technique used in manufacturing and process management to prevent errors or defects from occurring during production or operations. The goal of poka yoke is to design processes and systems in a way that makes it nearly impossible for mistakes to happen, thus improving quality and efficiency.
Poka-yoke can involve various methods, such as designing physical or mechanical features that prevent incorrect assembly or operation, using visual cues to guide operators, or implementing software checks to catch errors before they occur. The concept was popularized by Japanese engineer Shigeo Shingo as part of the Toyota Production System, where it became an integral part of lean manufacturing principles.
