POKAYOKE

Poka-yoke is a Japanese term that means "mistake-proofing" or "inadvertent error prevention". The key word in the second translation, often omitted, is "inadvertent". There is no poka-yoke solution that protects against an operator's sabotage, but sabotage is a rare behaviour among people.

The term poka-yoke was applied by Shigeo Shingo in the 1960s to industrial processes designed to prevent human errors.

Shingo redesigned a process in which factory workers, while assembling a small switch, would often forget to insert the required spring under one of the switch buttons.

In the redesigned process, the worker would perform the task in two steps, first preparing the two required springs and placing them in a placeholder, then inserting the springs from the placeholder into the switch. When a spring remained in the placeholder, the workers knew that they had forgotten to insert it and could correct the mistake effortlessly.

Shingo distinguished between the concepts of inevitable human mistakes and defects in the production. Defects occur when the mistakes are allowed to reach the customer. The aim of poka-yoke is to design the process so that mistakes can be detected and corrected immediately, eliminating defects at the source.

Poka-Yoke is a system to prevent mistakes from happening or immediately catches any mistake that has happened so that it can be corrected.

Human errors are inevitable in any process, but for every ϖ error, there is a cause(s) that can be corrected or a system implemented to detect the error for correction.

Defects occur when mistakes are allowed to reach the customer; the aim of Poka-Yoke is to design processes so that mistakes are prevented or corrected immediately, thus eliminating defects at the source.
