One of the factors that make great companies so great is that they have processes that allow them to solve difficult problems again and again. These processes have developed over time as teams have successfully wrestled with a certain type of challenge. Eventually, people begin to say, "This is just how we do something around here." The problem develops when that team then has to solve a very different set of challenges. The processes that are such strengths can be crushing liabilities.

Another thing I've observed is how critical the role of the CEO is when a technology truly is disruptive. In looking back on companies that have successfully launched independent disruptive business units, the CEO always had a foot in both camps. Never have they succeeded when they spin something off in order to get it off the CEO's agenda. The CEOs that did this had extraordinary personal self-confidence, and almost always they were the founders of the companies.

It is when the product is not good enough that proprietary integration gives you a competitive edge. You cannot outsource and be competitively successful in this situation. But at the other end, where standard components assembled in standard ways can yield acceptable performance, you must outsource.

In my first career I had founded my own company, with a group of MIT professors, before coming to Harvard to finish my doctorate, and so I had a deep respect for the brains, talent, and dedication of managers. That made it hard for me to believe the attributions in the business press that stupid management was to blame. So I looked elsewhere for an explanation.

Almost always great new ideas don't emerge from within a single person or function, but at the intersection of functions or people that have never met before.
