New Six Sigma?

In response to the announcement of a new version of SixSigma I formulated the following response:

I have studied many different continuous improvement methodologies over the years and would love to learn more about the the new kinder, friendlier Six Sigma, known as  "The New Discovery". Since I have always worked at smaller companies (the largest about 400 employees), I have always considered Six Sigma to be just what you have described, not really bad, just not a one size fits all approach (like Lean). Once one throws out the management structure (see ISIXSIGMA.COM ), all you really have left is a few statistical tools, project selection methodology, and the DMAIC process (which I honestly prefer over PDCA for a single process).

In the 90's, I worked for fabricated metal products company that was a first tier supplier to Motorola in Ft. Worth, Texas. I held the position of Quality Liaison to Motorola as well as a few other large corporations at that time. I had an opportunity to work with some great people, that had a very narrow directive (reduce variation). Years later, upon reflection (after the Motorola plant was shut down, all outsourced for cost savings I suspect), I have come to believe that Six Sigma lacks some things that I have found in Lean. Social responsibility, respect for people, and looking at the system as a whole, are the first things that come to my mind today when I compare the two. I imagine that I am not the only thinker out there who recognizes these things and I am certain there are more differences that I haven't thought of.

Hopefully the New Discovery was that Six Sigma was not a complete management philosophy but a project management system wrapped around some statistical tools that are great for companies of a certain size and type, but can not stand alone without further evolution.

I suppose I will have to give the new and improved version of Six Sigma a chance. I realize, having graduated from the school of hard knocks myself, one doesn’t need an impressive pedigree in order to become something of value to many.
