The problem of management is not what people don’t know about it. The Problem is what they think they do know. . . . In this regard, management has much in common with sex. Everyone is for it (under certain conditions of course). Everyone feels they understand it (Even though they wouldn’t want to explain it). Everyone thinks execution is only a matter of following natural inclinations. (After all, we do get along somehow). And, of course, most people feel that all problems in these areas are caused by other people (if only they would take the time to do things right).
