Grow a Great Orange:

Joel Podolny who works at Apple explained " Capture  (the value other creates) how you squeeze more juice out of orange. It's not about how you grow a great orange. In business schools, we really teach people how to squeeze oranges - how to manage for greater efficiency and economies of scale-not how to grow new and better oranges, which requires a different kind of thinking.
