AlwaysOn has an interview with Michael Raynor about his book “The Strategy Paradox: Why Committing to Success Leads to Failure (and What To Do About It).”
The same strategies that have the highest probability of extreme success also have the highest probability of extreme failure. In other words, everything we know about the linkage between strategy and success is true, but dangerously incomplete. Vision, commitment, focus…these are all in fact the defining elements of successful strategies, but they are also systematically connected with some of the greatest strategic disasters.
For example, Apples strategy sometimes works great, and sometimes fails miserably. Its not that Apple sometimes forgets what makes for greatness. Its that what makes for greatness also exposes you to catastrophe. The same goes for Sony.
