POKA-YOKE - A Lean Strategy to Mistake ProofingTimothy Wooi
A Lean Strategy in Human Error Prevention aims to detect and correct possible error immediately, eliminating defects at the source.
Poka-Yoke overcome the inefficiencies of inspection through the use of automatic devices that seek,
1.Not to accept a defect for the process
2.Not to Create a Defect
3.Not to Allow a Defect to be passed to the next process
Its purpose is to eliminate product defects by preventing, correcting, or drawing attention to human errors as they occur.
The concept was formalized, and the term adopted, by Shigeo Shingo as part of the
Toyota Production System.
It was originally described as baka-yoke, meaning "fool-proofing“ or “idiot proofing” but the name was later changed to the milder poka-yoke.
