There needs to be conviction and action behind rules.

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.

The outsourcing gurus have been driving the theory, and they are saying everybody ought always to do this. But it is really contingent on where you are on the spectrum from "not good enough" to "more than good enough," relative to each tier of the market.

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.
