What is Six Sigma?   By Janice Brand  January 22,  2003 — It sounds like a breakout room in some  Star Trek  convention. No, wait, with "black belts,"  it must be some Kung Fu movie thing. But what about “CTQs” and the “trivial many”? Have we  stumbled into some existential French movie genre?  None of the above. Six Sigma is a corporate quality program, one that emphasizes identifying and avoiding  variation. Depending on whom you ask, Six Sigma was born anywhere from 10 to 20 years ago in corporate  engineering communities, which are in the habit of reducing processes to statistically measurable  phenomena (the cornerstone of Six Sigma).  What’s with that name? The term “Six Sigma” is a statistical term that refers to 3.4 defects per million opportunities (or 99.99966  percent accuracy), which is as close as anyone is likely to get to perfect. A defect can be anything from a  faulty part to an incorrect customer bill. Six Sigma teams use extremely rigorous data collection and  statistical analysis to ferret out sources of errors and to find ways to eliminate them.
