Six Sigma is a hoax! Or, is a key to quality? ISO 9000 is a hindrance. Or is it a roadmap to quality? Judging by the mail received during the last couple months, Six Sigma and ISO are all of these things.
How can it be all of these things? Well, the simple answer is that the world isn't black and white, and what works for one company may not work for another. The real question is, "What is best for your company?" Or, put another way: "How does one know? Whom does one trust?"
