People say that ideas aren't important in business. Okay, people say, maybe an idea for a new product, but the rest is all execution, making it happen. Not so. As the strategy revolution demonstrated, ideas can be the key tools for making your business competitive.

The best discipline, maybe the only discipline that really works, is self- discipline.

Most of the experts agree that strategy will have to become more "adaptive", meaning that strategies will change faster based on information from people on the corporation's front lines - dealing with customers, fending off competitors. This won't represent a new revolution, but rather the continued speeding up of the one that's been going on. Everything will move faster, and competitive advantage disappear more quickly than ever.

The business schools could do a better job teaching face-to-face management, the actual work of organizing and helping along the efforts of others in the organization. The more quantitative disciplines have gotten more attention, often more research dollars. Areas like organizational science or, even mushier, leadership have had more trouble settling on what it's important to teach, and how. It's rather like strategy itself, which as I argue in the book, has had trouble through most of its history figuring out how to incorporate people, their motivation and ability, into its calculations.

People believe that management consultants are mostly useless parasites. Up until about 1980 it was consultants more than anyone else who came up with the critical concepts behind strategy. The history of strategy suggests there are lots of things consultants can do for a company that the company can't typically do for itself.

One practical point many experts will attest to is that if you want to develop someone as a leader, give them lots of responsibility early in their lives and careers. The military does that. I can remember being officer of the deck on a destroyer, on watch and in charge at two in the morning as we plowed through the Mediterranean while 300 shipmates slept below decks. I was 25 at the time. I don't know how much of a leader I ever became, but the experience certainly brought home to me a sense of responsibility for others.

I argue that once it became clear that the most important function of the CEO was to develop and enact the corporate strategy, that often had the effect of distancing him from people below him in the organization. It also encouraged the idea that if a CEO were a great strategist for a company in one industry, he would probably be a great strategist in another industry. And that usually hasn't proved to be the case.
