In this new video by Paul Akers, he takes some time define Lean. It is not about efficiency or killing muda. Lean is about 2 elements: 1) Learning to see waste 2) Eliminating waste with small continuous improvement with everything endlessly. You can't be "Lean". Lean is a journey. The big Muda that starts the waste cycle is over-production, as it causes all the other wastes.
Lean is seeing the eight wastes and then eliminating them through deliberate, consistent, endless, relentless, fanatical continuous improvement of everything you do everyday for the rest of your life to serve your customer.
Paul says this is the most important video he has produced. What do you think?
