There are some sound principles in Six Sigma. There are also some gross misunderstandings and optimizing towards meaningless metrics just because it makes things look good in the Six Sigma world. I’ve been an engineering lead in an organization which worked by Six Sigma. It provided a nice, standardized framework and a focus on metrics, but I’ve seen people again and again take absolute shit and “optimize” it to meet the metrics instead of fixing the underlying issues. I’ve seen another person (VP level, former professor) get to very illogical conclusions because Six Sigma methodology said so. So I’m all for adopting some Six Sigma principles as an underlying quality process, but please use sound judgement together with it.
