Poka yoke was initially conceptualized in Japan long ago by Shingeo Shingo, and he was employed in the Toyota as an engineer. This Japanese engineer originated the idea of poka yoke basics which the error-proofing plan. Also, by the realizing its value, it is an adequate quality to control the techniques. In the today's world, this concept is very famous in worldwide.

Furthermore, in Japanese poka yoke has a meaning which means mistake proofing. The purpose of the yoke is to avoid and poke means inadvertent errors. Therefore, poka yoke is a technique which builds the mechanism into a process which prevents the people from making the mistakes. Moreover, it is not possible for the human to act or work like the machinery and want the error-free result each time. 

If there is any problem or any minor interruption or the distraction is there, the result can come entirely incorrect. Also, the badly designed processes need an excellent supervision to get rid of the unwanted problems. The best part of the poka yoke is it always encourage the developing or the designing equipment’s and check the methodologies which is very much difficult for anyone to make any errors. Also, it is based on the principle where everybody should operate collectively to accomplish zero errors, and that product excellence starts with an immeasurable perspective. 

It eliminates all the errors, and it helps to improve the quality.It decreased the setup times with the associated reduction in the production time and helped to improve the production capacity.The process is very simplified, and it improves the housekeeping. Also, it increases the safety.This concept has very low cost, and it increases the production flexibility. Moreover, it helps to improve the operator attitudes.

Poka yoke is based on the prophecy and apprehension. Moreover, the poka yoke is classified into two types. The control poka yoke does not accept the process which begins or recapitulate after an erroneousness has befallen. Also, it accepts the acknowledgment to a particular variety of fallacy out of the hands of the operator. For, example when the machine is fixed, and it is equipped with the sensing device the process will not continue further if the part is not correctly inserted. Also, the floppy disk will not work successfully if it inserted backward or upside down.

The second type of the poka yoke gives some kind of warning when there is an error occurs. Moreover, this does not prevent any error, but the whole process will stop immediately when the error is detected. However, this type of poka yoke is very much useful for the mass production environments with the rapid processing. Moreover, the automatic controls are beneficial, and it is very useful. The design is made so beautifully that it does not allow any mistakes. Also, the automatic guides can help to reduce the errors, and it is often designed in a significant way.
