Six Sigma vs Lean Six Sigma
What is the difference between “Six Sigma” & “Lean Six Sigma”?
“Lean Six Sigma” simply means a program that includes “lean” principles in the Six Sigma Curriculum.
However, with that being said, it is important to realize that essentially all quality Six Sigma programs already have “Lean” principles incorporated into their curriculum. Therefore, most (if not all) “Six Sigma” programs are actually identical to their “Lean Six Sigma” counterparts.
In a nutshell, in today’s world “Six Sigma” and “Lean Six Sigma” essentially mean exactly the same thing.
The primary reason for the widespread confusion over the naming convention is because although Six Sigma began decades ago, it was only when the military began implementing it that it became a household name. However, since the military often referred to it as “Lean Six Sigma”, the full name became popular… causing mass confusion ever since.
However, to accommodate employers and employees alike, we offer both varieties.
If you are unsure of which to choose, we typically recommend “Six Sigma” for most people. We recommend “Lean Six Sigma” for those that work in the public sector or armed forces.
