“In knowledge work, the task is not given, it has to be determined.”

Professor of Management at New York University from 1950 to 1971. From 1971 to his death he was the Clarke Professor of Social Science and Management at Claremont Graduate University.

Drucker was interested in the growing importance of people who worked with their minds rather than their hands. He was intrigued by employees who know more about certain subjects than their bosses or colleagues and yet had to cooperate with others in a large organization. Drucker analyzed it and explained how it challenged the common thinking about how organizations should be run.
