OK, so Six Sigma is impressive cause nothing says INOVATION like spending 6 months proving with a laminated chart that people occasionally make mistkes... then assigning Greek letters to the revelation so it feels scientific.
its greatest achievement is turning common sense into a certification ladder... where every workplce problem can be solved by a belt-ranked priesthood... armed with acronyms, control charts, and the spiritual conviction that if a process still fails it simply has not been measured into submission hard enough...
So, yea - Six Sigma is the way to go...
