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.
