All About Poka Yoke & Mistake Proofing

What is Poka Yoke?
Poka-yoke was developed in the 1960s at Toyota by one of their industrial engineers, Shigeo Shingo.
Shingo had also coined the idea of producing zero defective items using Poka Yoke, which are small tools that can help prevent the defects from occurring in the first place. This helps companies achieve zero defects in a very simple manner.
The simplicity of Poka Yoke is due to its ability of being created by any employee, may it be a manager, sales assistant or any other employee of the organization who sees the need and has the idea to do it.
