Poka Yoke

Definition: Poka Yoke is a method that shapes a (production) process in such a way that it gets almost impossible to make mistakes and errors can not occur by human failure or process interference.
P-Y is a Japanese term which means "mistakes-proof".
The purpose of PY is to eliminate product defects by preventing, correcting, or drawing attention to human errors as they occur.
Employees are invited to suggest improvements in the process (Quality Circles).
The concept is part of the Toyota Production System and Lean Manufacturing.
Long before that, Taylor's Scientific Management was already trying to avoid errors by employees and to work in the most efficient and effective way.
