So is almost every other piece of software. I would like to see an analysis of commercial closed source software on how many of then use good practices, have clean code etc. Not the ones that filled in the [] we y use TDD in the CIO monthly questionnaire. Maybe I meet the wrong companies I have to work or integrate with, but in my experience it is not very far from 0% (but it is >0 luckily). I met one company last week who do everything right, but only for projects over 500k where over 10% goes into those practices, otherwise there is simply no money for the overhead...
