Good article. As a manager, I know that I started out as a dictator (isn't that why they asked me to be the boss?), evolved into a machine (after all, I was on the debate team in high school), and am now learning the art of the Jedi master (you know best, but have you thought about this?). But agree that all three modes have their places, and a good manager has to be able to use more than one of these at different times to be effective.
