The Hedgehog Concept (Simplicity within the Three Circles). To go from good to great requires transcending the curse of competence. Just because something is your core business — just because you’ve been doing it for years or perhaps even decades — does not necessarily mean you can be the best in the world at it. And if you cannot be the best in the world at your core business, then your core business absolutely cannot form the basis of a great company. It must be replaced with a simple concept that reflects deep understanding of three intersecting circles.

The good-to-great leaders understood three simple truths. First, if you begin with “who,” rather than “what,” you can more easily adapt to a changing world. If people join the bus primarily because of where it is going, what happens if you get ten miles down the road and you need to change direction? You’ve got a problem. But if people are on the bus because of who else is on the bus, then it’s much easier to change direction: “Hey, I got on this bus because of who else is on it; if we need to change direction to be more successful, fine with me.” Second, if you have the right people on the bus, the problem of how to motivate and manage people largely goes away. The right people don’t need to be tightly managed or fired up; they will be self-motivated by the inner drive to produce the best results and to be part of creating something great. Third, if you have the wrong people, it doesn’t matter whether you discover the right direction; you still won’t have a great company. Great vision without great people is irrelevant.

The flywheel, when properly conceived and executed, creates both continuity and change. On the one hand, you need to stay with a flywheel long enough to get its full compounding effect. On the other hand, to keep the flywheel spinning, you need to continually renew, and improve each and every component.
