Incidentally, every manager who struggles with getting more out of his or her people and has had no success with using "the carrot" may want to see how effective a motivator "the whip" can be by observing the aforementioned Gordon Ramsay at work on BBC America or Fox's "Hell's Kitchen".
His affinity for swearing aside, he demonstrates that passion about one's work and a refusal to accept anything less than perfection can effectively lead as an example that people of substance will follow.
The challenge is to get people to go beyond the boundaries they've set for their own capabilities - so few people set limits for themselves that allow them to truly shine. Ramsay is adept at getting people to shatter their illusions of their own limits and capabilities, even if his methods are found to be questionable. You can't argue with results. This guy was England's "Chef of the Year" for 9 years running. If you know how hard it is to get three Michelin stars, you understand how good he is at what he does.
