A while back I saw an interview with a NASA engineer they loaned to SpaceX for six months. He described a meeting in which two engineering proposals were being debated, and at the end Musk said "ok we'll do it this way" and that was the end of it. The guy was kinda blown away, and said at NASA they'd have had a dozen more meetings first. Given that SpaceX lives or dies by how well their rockets work, I don't think there's really anything more important for Musk to be doing.
