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.

When the functionality of a product or service overshoots what customers can use, it changes the way companies have to compete. When the product isn't yet good enough, the way you compete is by making better products. In order to make better products, the architecture of the product has to be interdependent and proprietary in character.

If the theory accurately predicts what they [scientists] see, it confirms that it's a good theory. If they see something that the theory didn't lead them to believe, that's what Thomas Kuhn calls an anomaly. The anomaly requires a revised theory - and you just keep going through the cycle, making a better theory.

Generally, the technology that enables disruption is developed in the companies that are the practitioners of the original technology. That's where the understanding of the technology first comes together. They usually can't commercialize the technology because they have to couple it with the business model innovation, and because they tend to try to take all of their technologies to market through their original business model, somebody else just picks up the technology and changes the world through the business model innovation.

I was lucky enough to build on the work of a number of people who had already run laps around this theory-building track. The original classification scheme, years ago, distinguished radical from incremental change. The theory said that established firms managed incremental change well, but would be expected to founder when their industry encountered a radical change.

The innovations are far more important because the technology itself has now way to impact the world for good until it's embedded in the business model. Innovation it's the combination of the simplifying technology and the business model.
