Who owns Lean Six Sigma? Is there an official BOK?

Nobody and No.
ASQ is by no means an authority on rigorous tasks, conditions and standards…merely a content and cert deliverer that many in the know don’t look to highly upon.I would suggest starting right here. Peruse the blue bar to the left and click on “new to six sigma”.

Correct

The only cut we give to Mikel is we buy his drinks if he doesn’t
run away when we are in bars together. He runs away lately.

You may claim that if you wish. Stan can have Six Sigma if Dr. Harry will let him. But it was Michael George who actually published the first book with the name Lean Six Sigma. Others may talk but you can actually find the book on Amazon and check the copyright date. But the question was regarding the Book of Knowledge. In that respect, there is no agreed upon BOK and thus no owners.

Darth,
Carnell does spell poorly but is very good at the use of spell check which unfortunately this Discussion Forum has never put into place.
Some have spent their time honing their spelling skills and others had added value to society by learning other less easy to automate skill sets.
There was a time when Mikel wanted a toll. He chose to back away from it purely on his own. There is a soul in there.
Just my opinion.

McGraw Hill published the hardback in 2002. I see your softback was published in 2001 so you got to market first with the integration. I also see that Amazon has a published date of 1899. Sorry, I can’t buy that one. Interestingly, this is the product description: This is the book that you want every company employee, especially the executive leaders and middle management, to read before you start your Lean/Six Sigma deployment. The authors have done an excellent job of explaining in a non-technical manner the Six Sigma problem solving methodology MAIC (Measure, Analyze, Improve, and Control) and why it is critical that it be linked to the 5S’s of Lean Enterprise. Focus on MAIC shows how long ago this was and I am not sure what the 5S’s of Lean Enterprise is. Sure hope your linkage of Lean and SS was more than just 5S.

Darth,
I was on a speaking agenda in Rochester, New York with Womack. I had seen him present before and he never seemed to acknowledge the existence of SS (my perception). In that presentation he had about 50 slides and had SS mentioned on 5. We wrote the book fast because we knew we did not want Womack to be the person to define the integration.
We probably were first to market because we self published because we were trying to stay true to Lean principles and print on demand. We soon found that the realities of the publishing world hit and that system runs on push not pull so when McGraw Hill bought it distribution was more effective.
When it comes to Lean I will put money on Barbara Wheats knowledge and understanding of Lean aginst anyone I have met to date. She is way beyond 5S.
