re: Lean Six Sigma - Anyone Tried This?

Go read a few books on it, and save yourself the $$. Certifications from any non-name brand entity in that sort of thing doesn't hold very much weight.

I work in Business Management Consulting, seems like 1 out of every 5 people have some sort of belt these days...

Edit: for reference, I have a black belt from CAT with projects producing $1m+ in financial benefit to the dealership I worked for.
