Quote Author: Peter Ferdinand Drucker

Peter Ferdinand Drucker

Peter Ferdinand Drucker

Peter Ferdinand Drucker (November 19, 1909 - November 11, 2005) was a writer, management consultant and university professor. His writing focused on management-related literature. Peter Drucker made famous the term knowledge worker and is thought to have unknowingly ushered in the knowledge economy, which effectively challenges Karl Marx's world-view of the political economy. George Orwell credits Peter Drucker as one of the few writers who predicted the German-Soviet Pact of 1939.

Unless commitment is made, there are only promises and hopes ... but no plans.

The most important thing in communication is to hear what isn't being said.

A business exists because the consumer is willing to pay you his money. You run a business to satisfy the consumer. That isn't marketing. That goes way beyond marketing.

Whenever you see a successful business, someone once made a courageous decision.

The success and ultimately the survival of every business, large or small, depends in the last analysis on its ability to develop people. This ability is not measured by any of our conventional yardsticks of economic success; yet, is the final measurement.

Economists think the poor need to tell them that they are poor.

No organization can depend on genius; the supply is always scarce and unreliable. It is the test of an organization to make ordinary human beings perform better than they seem capable of, to bring out whatever strength there is in its members, and to use each man's strength to help all the others perform. The purpose of an organization is to enable common men to do uncommon things.

Leadership is not magnetic personality that can just as well be a glib tongue. It is not 'making friends and influencing people' that is flattery.

Teamwork is neither 'good' nor 'desirable.' It is a fact. Wherever people work together or play together they do so as a team. Which team to use for what purpose is a crucial, difficult and risky decision that is even harder to unmake. Managements have yet to learn how to make it.

Until we can manage time, we can manage nothing else.

'Management' means, in the last analysis, the substitution of thought for brawn and muscle, of knowledge for folkways and superstition, and of cooperation for force. It means the substitution of responsibility for obedience to rank, and of authority of performance for the authority of rank.

Quality in a product or service is not what the supplier puts in. It is what the customer gets out and is willing to pay for. A product is not quality because it is hard to make and costs a lot of money, as manufacturers typically believe. This is incompetence. Customers pay only for what is of use to them and gives them value. Nothing else constitutes quality.
