Management by objective works - if you know the objectives. Ninety percent of the time you don't.
Peter DruckerThe more successful the unit, the more difficult it is to make sure that the large company doesn't put the same expectations on it as it does for the rest of the company. When it's a new venture, whether it's outside or inside the business, it's a child. And you don't put a 40-pound pack on a 6-year-old's back when you take her hiking.
Peter DruckerNothing else, perhaps, distinguishes effective executives as much as their tender loving care of time.
Peter DruckerNever underrate the boss! The boss may look illiterate. He may look stupid. But there is no risk at all in overrating a boss. If you underrate him he will bitterly resent it or impute to you the deficiency in brains and knowledge you imputed to him.
