- Here be dragons. I think we need to distinguish between TQM, which is a
- methodology for improving processes, and testing, which is a methodology
- for finding defects. TQM is about improving a process so that it runs
- more efficiently and produces fewer defects. Testing is about finding
- defects before the customer does. Robert, if your point is that once
- one has a _mature_ TQM program in place throughout the organization one
- will expend fewer resources on testing and testing-related coding, then
- I'll buy that. However, I believe it would be very foolish for any
- company to scrap its testing efforts entirely immediately upon starting
- at TQM program. TQM is a long term investment, while testing is a risk-
- reduction effort.
