My response to the message, Has Six Sigma been a failure? (broken link was removed) on the Deming Electronic Network email list (DEN).
I think Six Sigma has been a success. Do I think it the best option? No, I would prefer a Deming based approach. But I think Six Sigma can be a successful improvement strategy. Like most any management strategy, many applying it do so poorly (hacks as Deming would say). But if most any DEN participant worked with the leading thinkers in the Six Sigma community you would find they fit very well within the community of the DEN, though with some distinguishing traits.
To varying extents the Six Sigma thinkers might not accept the level of importance we place on certain items, things like: “joy in work,” co-operation (vs. Competition), the need to change the organizations culture, the importance of unmeasurable factors, or eliminating performance appraisals. But the best minds (as I see it) in the Six Sigma community share our beliefs, to a large extent. The approach they have taken is to work with the current culture more than most of us would like, if we could instead have the culture move toward a more Deming based culture.
Many Six Sigma proponents have done great things: Gerry Hahn, Roger Hoerl, Soren Bisgaard, Bill Hill, Ron Snee, Forrest Breyfogle. They happen to all be statisticians, I believe; as were most (though not all) of those who taught with Deming. I think there is a connection.
