It looks like Mulally has turned around large, moribund businesses like Ford and Boeing from complete mediocrity to relative competence. I don't mean that in a negative way, because it's miraculous for a company like Ford to turn around the way they did, but let's be honest here. Jobs led a large, established company into being the most valuable public corporation in the world, competing successfully not with behemoths like GM but with Silicon Valley. Name a tech company half the age of Apple that can even hold its own against the forces of creative destruction in the Valley, much less grow like a startup.
