Isn't Lean six sigma already something of a buzz word? I've never taken six sigma training but I remember my statistics professer talking about that and ISO this and ISO that and Six Sigma....sounded like a bunch of bull**** thats good to have on a resume (the principals might be there, but the rest is repackaged bull**** that'll be ditched in a few years for the newest repackaged bull**** program...)
ISO (ISO 9001) and Six Sigma/Lean Sigma are totally different animals. ISO 9001 is an international quality standard to which companies can become certified. It is a way for organizations to demonstrate their committment to quality, and isn't really all that difficult to achieve.
Six Sigma is a statistical approach to problem solving. It's basically the same principles that Deming was teaching to the Japanese after WWII. Six Sigma is based on the following: Define, Measure, Analyze, Improve, Control (DMAIC). 50 years ago, Deming taught Plan, Do, Check, Act, so really they are one and the same. TQM, SPC, Deming, Six Sigma, etc. are different statistical approaches that are basically doing the same things.
