I find your comments interesting! Motorola was the first to implement 6 Sigma and after 5 years of application to it manufacturing entities claimed (I think this is the right number) $5 billion in savings. they then applied it to their transactional business and got about the same savings in only one year.
You are right in that 6 Sigma is basic statistics. It is how you apply them and what you measure that makes it work. Throw in the philosophy of Lean Management and you have tools and concepts that can create real savings.
I know of one carpet company that sent people for Lean Sigma training. As a result of applying what was learned during the training they were able improve the quality of the product, increase the width of the product, make rolls that held more yards of carpet, and most importantly, meet the needs of new unserved customers.
Six Sigma means less than 2.65 errors in 1,000,000 attempts or opportunities. I think that any company that can do this is going to benefit.
There are way too many companies utilizing this to not pay attention to it!
