It is not possible to eliminate all the mistakes people make. People are not mistake proofed by their nature. But organization can avoid these mistakes from reaching the customer, which is known as a defect in this case. Mistakes can be stopped as soon as they happen at least. Poka-yoke is very simple concept in nature. The basic concept of this is avoiding the problems by correcting the process. Poka-yoke is a quality assurance technique developed by Japanese manufacturing engineer Shigeo Shingo. The aim of Poka-yoke is to eliminate defects in a product by preventing or correcting mistakes as early as possible. So what is mistake proofing? The use of process or design features to prevent errors or their negative impact. Also known as Poka yoke, Japanese slang for “avoiding inadvertent errors” which was formalized by Shigeo Shingo. A method that uses sensor or other devices for catching errors that may pass by operators or assemblers. Shigeo Shingo defines Poka Yoke as: Poka ? “Inadvertent Mistake That Anyone Can Make” [2] and Yoke ? “To Prevent or Proof” [1]. Poka -Yoke performs two key operations of ZDQ (Zero Defect Quality) i.e. identifying the defect immediately ( Point of Origin Inspection) & quick feedback for corrective action. Poka-yoke detects an error, gives a warning, and can shuts down the process.
