It derives from statistics where given a gaussian (bell) distribution, the probability of anything outside 3 sigma (sigma is a ususally the standard deviation) from the average is like .999997 or something close to that, which is basically 1 in a million. Motorola was big into this basing their near zero defect quality project on this catch phrase. --------- Christopher R. Bowman crb@Glue.umd.edu <A HREF="http://www.glue.umd.edu/~crb">My home page</A>
