Hi Greg, well said. However, some Mr. Taguchi developed a quality function loss theory, that seems more exhaustive to me when interpreting quality risks. As a quality professional myself, I'm well aware that quality professionals' vision is warped by conformity, instead of focusing on risk - though, as living creatures, we are much more concerned with risk than with quality. I do really wish the up-coming ISO 9001 will put aside the sin-tasting concept of conformity and be more practical on risk factors. Thank you.
