The elements of poka-yoke like with any other tool in lean six sigma, there are some steps you need to follow to get the most out of mistake proofing your projects. A key architect of the toyota production system, shingo wrote about his discovery and development of mistake-proofing in zero quality control, source inspection and the poka-yoke system. 6 mistake proofing roi dana corporation has reported a $500,000 savings resulting from a $6 device ortho-clinical diagnostics(johnson & johnson)saved $75000 annually by discovering a new use of post-it®® notes. Poka yoke means 'mistake-proofing' or more literally - avoiding (yokeru) inadvertent errors (poka) poka yokes ensure that the right conditions exist before a process step is executed, and thus preventing defects from occurring in the first place. A combination of source inspection and mistake-proofing devices is the only method to get you to zero defects shigeo shingo shows you how this proven system for reducing errors turns out the highest quality products in the shortest period of time shingo provides 112 specific examples of poka-yoke.
This system is called poka-yoke, a japanese term that means mistake-proofing it was first developed in toyota motors of japan by shigeo shingo, who assisted taiichi ohno in creating the toyota production system, also known as the just-in-time production or lean manufacturing. Shigeo shingo demonstrated the concept of poka-yoke in 1961, the initial term was baka-yoke, which means 'fool-proofing' or 'idiot proofing' due to the term's offensive connotation, the term was changed to poka-yoke, which means 'mistake-proofing. Poka-yoke is japanese for mistake-proofing these devices are used either to prevent the special causes that result in defects, or to inexpensively inspect each item that is produced to determine whether it is acceptable or defective.
Either the operator is alerted when a mistake is about to be made, or the poka-yoke device actually prevents the mistake from being made in shingo's lexicon, the former implementation would be called a warning poka-yoke, while the latter would be referred to as a control poka-yoke. Also called: poka-yoke, fail-safing mistake proofing, or its japanese equivalent poka-yoke (pronounced po-ka yo-kay), is the use of any automatic device or method. Poka yoke literally means mistake proofing, it is about preventing the creation of defects usually it is a simple and inexpensive device or modification to the product itself to prevent there from being any possibility of defects being made.
Poka yoke poka yoke is a japanese term literally defined as 'mistake proofing' poka-yoke is often used in the context of designing devices, typically simple and inexpensive, that prevent defects from being made or, if they are made, from moving to the next process. poka yoke operations management sep, 2013 poka yoke (mistake proofing) poka yoke is a quality management concept developed by a matsushita manufacturing engineer named shigeo shingoto to prevent human errors from occurring in the production line. Mistake proofing is another six sigma tool most of the time integrated with other lean six sigma tools such as 5s visual management, quick changeover, standard work, and one piece flow sometimes called poka-yoke or fail-safing, it is characterized as an improvement procedure (or device) which aims to avoid or eliminate defects or errors from.
The concept of 'mistake proofing' (poka yoke in japanese) was introduced to the west in 1986 by shingo, a master mind of the toyota production system, in the book titled zero quality control: source inspection and the poka-yoke system. A combination of source inspection and mistake-proofing devices is the only method to get you to zero defects shigeo shingo shows you how this proven system for reducing errors turns out the highest quality products in the shortest period of time.
Proofing methods identified in nikkan kogyo shinbum's publication on poka-yoke in a broader sense, this any combination of guiding devices that fills the function of guides with different sizes - including slots, ribs, fasteners, and etc meet the intent. Mistake-proofing - fool-proofing - failsafing japanese industrial engineer shigeo shingo developed poka yoke (to avoid (yokeru) inadvertent errors (poka)) along with source inspection as a means for achieving zero quality control (zqc. Poka yoke relies on source inspection, detecting defects before they affect the production line and working to eliminate the defect cause mistake proofing mistake proofing is also a component of poka yoke. Mistake-proofing systems, also called poka-yoke systems, help prevent mistakes before they become defects a poka-yoke is a mechanism, device, or process that eliminates.
