poke yoke

a Japanese term meaning ‘to make fail-safe’. Any mechanism or process that prevents mistakes being made can be called a poke yoke. They are techniques and thinking designed to prevent errors in manufacture and service provision. The 3 pin plug is a simple poke yoke, it can only be inserted into the socket in one way, hence – fail-safe. Poke yokes have two broad functions, regulatory and setting. Regulatory devices are those that either control a process or give a warning about it. Control devices are used to shut a process down whenever it detects an abnormality. See PRODUCTION CONTROL.

Six Sigma specialists will tell you that "poka-yoke" or "mistake proofing" controls, such as those that make it impossible to open more than one drawer at a time on a filing cabinet (preventing tip-overs), can be relatively inexpensive, but require willingness to consider alternative methods of control than we are most familiar with.

"Poka-yoke" es una tecnica de calidad desarrollada por el ingeniero japones Shigeo Shingo que puede traducirse literalmente como "a prueba de errores", siendo habitual su aplicacion en el campo industrial mediante la introduccion de mecanismos que ayudan a prevenir y a evitar los errores antes de que sucedan (Hirano, 1990).
We use analysis results to drive to failure root cause and determine preventative corrective actions via design and poka-yoke in order to ensure our products have the highest level of quality and reliability built into the design prior to entering production.
