Michael Porter

If your goal is anything but profitability - if it's to be big, or to grow fast, or to become a technology leader - you'll hit problems.

The best CEOs I know are teachers, and at the core of what they teach is strategy.

You can't have a healthy society unless you have healthy companies that are making a profit, that are employing people and that are growing.

Good leaders need a positive agenda, not just an agenda of dealing with crisis.

Health care historically has been a very siloed field that's organized around medical specialties - urology, cardiac surgery, and so forth - and around the supply of these specialty services. The patient is the ping-pong ball that moves from service to service.

I teach in the medical school, the School of Public Health, the Kennedy School of Government, and the Business School. And it's the best perch... because most of my work crosses boundaries.
