Clayton Christensen, author of "The Innovator's Dilemma" and "The Innovator's Solution"

We had a special lecture today by Clayton Christensen, author of "The Innovator's Dilemma" and "The Innovator's Solution".  He gave a number of expamples of companies that have been able to sustain success through several business cycles, by innovation and reinvention, and also many examples of companies that did not.  One quote:

"If the capabilities of the past are what you need for success in the future, stick with them, but, if they are not...."

So, what "core competencies" will be important in the future?
