Lean Six Sigma is not Lean. It is Six Sigma, but one that is more "Lean" than just regular "Six Sigma." In the English language the adjective (Lean) modifies the noun or subject word (Six Sigma). So Lean Six Sigma is technically not Lean at all, but a form of Six Sigma that has less fat in it than regular Six Sigma.
Just like "diet soda" is not a form of diet but a form of soda.
"Six Sigma Lean" on the other hand, is redundant since Lean manufacturing already implies Six Sigma, in that the development of Lean manufacturing at Toyota comes directly from Deming's work on statistical quality control. Although they are not so popular elsewhere, QC Circles are active in Japanese companies as well as in Toyota. The whole "QC Story" approach to work team kaizen based on the scientific method is implied in Lean manufacturing. So I think that Six Sigma Lean is redundant.
Don't even get me started with Lean Sigma.
If there were a "soda diet" that made you thin by drinking just Cola, that might work, but I think this would just make you sick.
So what do we call the intentional merging of Lean and Six Sigma values, skills and tools?Comments are moderated to filter spam and inappropriate content. There may be a delay before your comment is published.
