bulldozers move mountains; ideas show where the bulldozers should go to work. - Peter Drucker

Measuring requires, first and foremost, analytical ability. But it also demands that measurement be used to make self-control possible rather than abused to control people from the outside and above — that is, to dominate them. It is the common violation of this principle that largely explains why measurement is the weakest area in the work of the manager today. As long as measurements are abused as a tool of control (for instance, as when measurements are used, as a weapon of an internal secret police that supplies audits and critical appraisals of a manager’s performance to the boss without even sending a carbon copy to the manager himself) measuring will remain the weakest area in the manager’s performance.2

Results are gained not by solving problems, but by exploiting opportunities.

Management by drive, like management by ‘bellows and meat ax,’ is a sure sign of confusion. It is an admission of incompetence. It is a sign that management does not know how to plan. But, above all, it is a sign that the company does not know what to expect of its managers – that, not knowing how to direct them, it misdirects them.
