Wow! I couldn't believe it when I was browsing through the New Posts and saw this...lol I've been Six Sigma certified as a Greenbelt since 2005, although I haven't used it since I got laid off. Honestly, I think it's good for anyone to have because the methodology can be used to improve just about any sort of process. When I got laid off, I was a Quality Assurance & Analysis (QA&A) manager, but dealt a lot with process analysis and improvement. As a greenbelt, I was the one that gathered the data, analyzed it, and created presentations and reports to show where there were breaks in the process and what portions needed to be improved on (mostly process time; total and parts). I was on my way to becoming a blackbelt before I got laid off. (In order to become a blackbelt you have to manage a Six Sigma project from start to finish. I had a project but a 2nd level manager stole it out from underneath of me because he was trying to get his blackbelt at the same time. Basically, I did all the leg work and he took all the credit

)
I still have ALL of my books and such and keep meaning to brush up on it because this is also something I've been toying with offering. If I do go this route, I'll probably have to become recertified as a greenbelt because I'm not sure that my certification is valid in the "real" world because I received my training from the AT&T School of Business (the company I used to work for) and not an outside vendor, so it was geared more towards telecommunications and services instead of widgets...lol However, the basic methodology would certainly still apply.
Anyhow, I say
GO FOR IT!!!!! I haven't been keeping up with what's going on with Six Sigma in a while and I know that the "newest and greatest" things change from time to time, but if it's still the standard then it would be a good thing to have.
By the way, just to warn ya, the class (at least the one I took) isn't the easiest thing in the world and the two hour exam is grueling. I was almost in tears by the time I was done because I was positively sure that I failed, but I didn't.
Sorry for rambling, but you just hit on what used to be one of my greatest passions
