I agree that it is hellishly difficult to hire for that kind of GTD ability. However I put it to you that if you have 25,000 employees, you must have fluked some of these personality types even with just technical interviews. Ergo if these people are not being leveraged, it says that your culture does not value those skills, and that you have some very frustrated people.
