Lean 6 sigma..........management buzz word for a very simple problem solving philosophy. This has been around for a long time, but was packaged into this "buzz word" managementspeak term, by a very savvy marketing firm. I went thru similar training in the Navy, about 20yrs ago, but it was then called T.Q.L. (Total Quality Leadership).....same principles, different packaging (and buzz word).....
You spend a week learning the technique, what it boils down to is: Logical problem solving, using result based common sense solutions.......
(Yes, I know it's confusing, if it wasn't they wouldn't be able to charge so much for the training)....
