Poka yoke mistake proofing and source inspection
Also known as mistake-proofing, goof-proofing, and fail-safe work methods, poka-yoke is simply a system designed to prevent inadvertent errors made by workers performing a process the idea is to take over repetitive tasks that rely on memory or vigilance and guard against any lapses in focus. Poka-yoke (poh-kah yoh-keh) was coined in japan during the 1960s by shigeo shingo who was one of the industrial engineers at toyota shigeo shingo is also credited with creating and formalizing zero quality control (poka-yoke techniques to correct possible defects + source inspection to prevent defects equals zero quality control. 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.
Poka yoke 1 lets understand cost of defect presently cost of poor quality is on very high company miserably failed to increase their profit. 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. The fundamental idea of source inspection and poka-yoke is to move physical and mental work from the operator to the machine and py devices this should never increase labour costs the additional cost that is accepted is the process-stop costs involved when a py device is activated.

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. 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.

A simple poka-yoke example is demonstrated when a driver of the car equipped with a manual gearbox must press on the clutch pedal (a process step, therefore a poka-yoke) prior to starting an automobile source inspection and the poka-yoke system mistake-proofing - fool-proofing - failsafing. This presentation gives a brief idea on what is poka yoke and the various types of poka yoke with examples it also talks about the short comings of poka yoke point of origin inspection (source inspection) poka yoke (mistake proofing) animesh khamesra poka yoke presentation. This is done by combining four basic elements 1: i)source inspection ii) 100 percent inspection iii) immediate feedback and iv) use of poka-yoke (mistake-proofing) devices zqc is widely.
Poka yoke mistake proofing and source inspection
Poke-yoke (mistake proofing) looks at the defect and stops the production, and gives immediate feedback to help find the root cause of the defect source inspection looks at errors before they become defects. Poka-yoke, in any of the various spellings, is another name for error- or mistake-proofing a design or process the focus of poka-yoke is to sensitize us about the differences between prevention and detection and to do something about it. 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. 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.
- 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.
- 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 is one of lean manufacturing pillars, together with: konnyaku stone, jidoka, hansei, andon, just in time, heijunka, kaizen, genchi genbutsu, nemawashi who invented poka yoke poka yoke was used for the first time in 1961 in japan.
Shigeo shingo introduced the concept of poka-yoke (pronounced poh-kah yoh-kay) in 1961, when he was an industrial engineer at toyota motor corp the initial term was baka-yoke, which means fool proofing. The system was based on poka yoke but was made bullet proof by the application of our 7 criteria of mistake proofing the system was implemented across the company quickly achieving the goal of zero defects in less than two years time. Poka yoke operations management sep, 2013 poka yoke (mistake proofing) shigeo shingo developed ‘mistake proofing’ and source inspection system that, employees can identify and absolutely eliminate product and process errors characteristics of good pokayoke decices: they are simple and cheap.
