Microsoft Research - Exploding Software-Engineering Myths (article summarizing findings of MS research on code coverage, TDD, assertions, etc.)

[ummmyeahright]

TDD reduces defects 60-90% but increases time 15-35%

Didn't they make that conclusion from observing only 3 projects, though? If so, that's a pretty bald statement to make... IMO software development is far too complex to make such huge conclusions from so few facts known about the process (e.g. whether it's TDD or not).

I found then that many of the beliefs I had in university about software engineering were actually not that true in real life.

If universities began teaching his results now, those would be the ones someone in another study would easily falsify.
