There appear to be a bunch of places issuing certification in Six Sigma training but are they all recognized? Wikipedia lists the following professional association:
American Society for Quality (ASQ)
Institute of Industrial and Systems Engineers (IISE)
Chartered Quality Institute (CQI)
Should I be looking at certification from these only of will any old one do for a resume bullet?
I’ve never heard of CQI, but the other two are long time prestigious organizations.
If you can get a certification from GE or Motorola, that would be good, too, but I don’t know if they are in that business.
Sorry, I neglected to actually answer the question! In my opinion as a quality/reliability engineer, I would not be impressed nearly as much by a certification from some outfit that I’d never heard of as I would if it were from one of those mentioned above, or from an industry leader. However, it wouldn’t do any harm, either. So if the ASQ or IISE options were too expensive or inconvenient, a no-name certification would probably be better than nothing.
Thanks! I guess I’ll go with IISE since I’m a (lapsed 
) member
