JIDOKA
(An
Improvement Tool of Lean)
Jidoka is a Japanese word that meansAutonomation
Autonomation –Automation with human intelligence.
It’s a practice of stopping the process when something goes wrong.
Originally, this concept was first used in 1896 by Sakichi Toyoda.
He first invented a textile loom that would stop automatically when it comes across a defective thread.
This seemed to be very useful in terms of: Time, Quality & Cost
Jidoka allows the operation to have a build in quality at each step of a process, so the operators does not have to watch the machine or the operation all the time.

Don’t accept defects
