When stress is the problem, slack is the solution.
Tom DeMarco
Managers who inspire extraordinary loyalty from their people tend to be highly charismatic, humorous, good-looking, and tall. So, by all means, strive to be those things. If you don't feel able to improve any of those factors very much, you might consider holding on to your people by designing a little slack into their lives.

Good management is the lifeblood of the healthy corporate body. Getting rid of it to save cost is like losing weight by giving blood.

Any vigorous competition will entail at least two elements: offense and defense. Offense is the effort you put into scoring against your opponents, and defense is the effort you apply to stop them from scoring against you. Those who suggest that "a little healthy competition can't hurt" are thinking only of the offense part....The offense component of internal competition is problematic, but the defense component is always injurious. When peer managers play defense against each other (try to stop each other from scoring), they are engaging in anticooperation.

If the essential task of middle managers is reinvention, when is that task to be carried out? The answer is, during time that is not used up directing day-to-day business. The fact that managers have time on their hands (i.e., their operations tasks take up less than eight hours per day) gives them time for reinvention. The extra time is not waste, but slack. Without it they could function in only their operational roles. Reinvention would be impossible because the people who could make it happen are just too busy to take the time.Even companies that didn't fire their change centers have hurt themselves by encouraging their middle managers to stay extremely busy. In order to enable change, companies have to learn that keeping managers busy is a blunder. If you have busy managers working under you, they are an indictment of your vision and your capacity to transform that vision into reality. Cut them some slack.

There is no such thing as "healthy" competition within a knowledge organization; all internal competition is destructive. The nature of our work is that it cannot be done by any single person in isolation. Knowledge work is by definition collaborative.

The business we're in is more sociological than technological, more dependent on workers' abilities to communicate with each other than their abilities to communicate with machines.
