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.

Designing and implementing manufacturing cells requires many engineering skills including machine design (ergonomics and safety), tooling design (rapid load/unload and quick changing), cutting tool design, process design (so machining times are less than cycle times), poka-yoke and decoupler designs (for zero defects and operator assistance and materials handling).
Shigeo Shingo, in his book A Study of the Toyota Production System (Productivity Press, 1989), discusses the use of poka-yoke devices (error-prevention devices) as a way to prevent the occurrence of defects.
