David's Time With Peter F. Drucker 2020.2.15 Introduction:Why Assumptions Matter BASIC ASSUMPTIONS ABOUT REALITY are the PARADIGMS of a social science, such as management. They are usually held subconsciously by the scholars, the writers, the teachers, the practitioners in the field. Yet those assumptions largely determine what the discipline——scholars, writers, teachers, practitioners——assumes to be REALITY.——《Management Challenges for the 21st Century·Chapter1》(Peter F.Drucker,1999)
