Recently I heard an interview that CNBC did with Lou Gerstner. He said his biggest contribution as CEO at IBM was changing its culture. His example of how he changed the culture is that when he came into the job there was a lot of talk about breaking up the company into smaller companies; he decided not to do that. In other words, his biggest contribution to IBM was NOT DOING SOMETHING. Then he wrote a best-selling book about his leadership. The Magic 8 Ball would have had a 50% chance making the same decision; a sock monkey would have nailed it on the first try.
