The two great pillars of the Lean system are:
Just - In - Time (prefer application - Pull Production)
Jidoka
It makes with that diverse cycle PDCA is a refugee and everything will go to flow ... wall lamp Kaizen of course, in system Jidoka and Just-IN-Time.
I find it interesting to see how new terms keep being created, such as six sigma and Lean, then these are twisted to mean anything users want them to mean. Sticking to solid foundations such as the teachings of Deming seems to be passe these days.
I hadn't heard of the amazing "new pillar", "Jidoka" ... a little research and I found "Jidoka, as applied to manned operations, refers to the practice of stopping the entire line or process when something goes amiss. " Now why hadn't I ever thought of doing that ? In actual practice, there are times when the knee jerk reaction of stopping a production line, prevents the analysis of faults that have developed.
