Six Sigma & Lean By Itself Is Not a Problem Solving Approach

I always emphasis that, in fact, there is no such thing like Six Sigma Problem Solving Approach. We have Six Sigma process level, but Not Six Sigma Approach.

This meant, we you achieve a Six Sigma process level, technically we can estimate the process will generate 3.4ppm defect level. But how to achieve this level ? This a question mark. You may apply PCDA, DMAIC or other problem solving methodology to achieve the level.

And LEAN to me is another problem. Similar to Six Sigma, LEAN is just a target, how to achieve this target ? You may apply above mentioned methodoly.

Why I say LEAN is a big problem here. Question... How LEAN is consider LEAN ? We cant measure now. So most of time we end up measure LEAN in Sigma Level as well.
