If a company truly wants to resolve the innovator's dilemma, it does need to be able to create wave after wave of disruptive innovation. And those disruptive innovations will typically grow to the point where they do cause some pain for leading companies. But most disruptive innovations create substantial new growth before they cause that pain.

The mistake managers often make is defining their industry too narrowly. Digital's market share in the minicomputer market stayed very robust even as it fell off the cliff. Disruption seems to come out of nowhere, but if you know what to look for, you can spot important developments well before the market does.

I've concluded that getting the categories right is an absolutely crucial step to building useful management theory, and unfortunately too few writers do this. You've got to engage in serious scholarship, and then figure out how to write it in a way that lots of people can understand.

One reason there are so many short-lived management fads is that their prescriptions were derived and advocated in precisely this way. So managers read about a fad and try it, find that it doesn't work, abandon the effort, and move on to the next thing. In reality, it is usually the case that the faddish prescription was indeed sound advice in certain circumstances, but actually was poor advice in other circumstances.

Each of our children during their high school years went to 'early morning seminary' - scripture study classes that met in the home of a church member every school day morning from 6:30 until 7:15.

We are all trained to be data driven people, but no hard data exist about the future. Therefore, the only way to look into the future with any degree of accuracy is to use theory, statements of what causes what and why. If executives have the right theories in their heads, they can very quickly interpret market developments. They can identify what matters and why, and act accordingly. So we suggest decision-makers should start by gaining a deep understanding of the relevant collection of theories, and then be alert for signals that indicate certain types of developments.
