What I meant was it's possible to implement such a system in the framework of a dow30 type culture. The few times that I've seen it implemented, management supported it. But without someone just taking the initiative and doing it, it doesn't happen. The average newly graduated junior enterprise developer with an average lead enterprise developer probably can't pull it off. So it could be enterprise just has to catch up and they are just not there yet. Maybe that makes it a cultural problem, I'm not sure.
No doubt, management has yet to see the light. They want data to show that change in their process and new technology works before they commit. There should be a place for it when management finally realizes it's not a fad but a trend.
