Optimizing processes that lose money

So far, we've discussed Stupid Six Sigma Tricks #10: Conflating systems, methods and tools and #9: Confusing breakthrough with continuous improvement. This month, I’ll spend some time on a more subtle, and no less costly mistake that, in its extreme form, we’ll call Stupid Six Sigma Trick #8: Optimizing processes that lose money.

Dogma and Definition

In Dirk Dusharme’s First Word in the April 2006 issue of Quality Digest, he sneaks into the back of the "Church of the Six Sigma" and cannily reports the goings on. In this bimonthly column, I will burst in through the doors dressed in motley and try to pry the scales off of your eyes, chanting, "DMAIC will set you free!"
