Strategy is about making choices, trade-offs; it's about deliberately choosing to be different.

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.

The essence of strategy is that you must set limits on what you're trying to accomplish.

Risk is a function of how poorly a strategy will perform if the 'wrong' scenario occurs.

Apple does all of its research and development in America. It has all these brilliant people sitting in Silicon Valley. But until recently, Apple made nothing in America. Zero. And the jobs that were accessible to a good, well-trained worker that knew how to do welding or assembly, none of those jobs had stayed in America. We don't have the workforce.

It is not on the margin of what companies do but at the center. We believe that it can give rise to the next major transformation of business thinking.
