Management has to provide the coordinating mechanism between what the supplier provides and what the user needs in not-good-enough situations where product architecture is consequently interdependent. Management always beats markets when there is not sufficient information.

My conclusion: Management is the most noble of professions if it's practiced well. No other occupation offers as many ways to help others learn and grow, take responsibility and be recognized for achievement, and contribute to the success of a team.

If the technology is disruptive, on the other hand, the odds are that at the end of the transition, the leaders will have been toppled and new companies will be on top.

If you ask the average guy on the street to name five companies that have truly transformed themselves over the few decades, Hewlett-Packard would be on everybody's list. You'd also put on this list GE and Johnson & Johnson.

Most companies think of disruption as a threat. But disruptive innovations have tremendous growth potential. If incumbent companies can learn how to harness the forces of disruption, they too can improve their ability to create new-growth businesses.

Focus is scary—until you realize that it only means turning your back on markets you could never have anyway. Sharp focus on jobs that customers are trying to get done holds the promise of greatly improving the odds of success in new-product development.
