- I feel almost silly to point this out (perhaps a smiley got lost in
- transmission???), but Deming and Taylor are opposite poles. Deming has
- been preaching against Taylor for forty years.

- I fully agree that CMM is consistent with Taylor. And I agree it's
- reasonable for DOD to be pushing CMM. Taylor deserves a lot of credit
- for the United States' pre-eminence in war-making; and it's likely that
- the Taylor model is _still_ better than the Deming model for war-making.

- Here's our problem. I'm entirely sure that the people who wrote CMM
- 4 and 5 have read Deming. Probably they've even extracted a number of
- good ideas from him. It may even be an ideal direction for American
- manufacturing to take. But until I get a chance to _read_ CMM 4 and 5,
- I'd bet against it. They're trying to graft Deming ideas onto a base
- really quite contrary to his teachings. This seldom works well.
