Past successes pose the greatest risk of future failure.

This statement, while accurate, is hardly original, whether applied to a business or a business executive. But Adam Hartung’s Create Marketplace Disruption: How to Stay Ahead of the Competition (2008) goes far beyond this commonplace observation. Hartung details its dynamics, allowing him to recommend practical ways to prevent it.

Quite a few of you asked for more information about this book. In particular, you asked about Hartung’s “Phoenix Principle” — his prescription for avoiding the stagnation and eventual disintegration that are the near-inevitable consequence of business success.

I’d call my friend Willy Chaplin a “character” if it weren’t subtly demeaning.

That wouldn’t be appropriate for a guy who, in addition to “getting” the Web before most of the rest of us (“The thirteen commandments of the World Wide Web,” Keep the Joint Running, 6/9/2008), has been at one time or another in his life a weapons designer, spy, programmer (if you enjoy backgammon, his on-line version is a must), commune-founding hippy, consensual bigamist, fugitive, jailbird, parent and grandparent.

Also an autobiographer, and an honest one at that.
