“This book undertakes the study of management by utilizing analysis of the basic managerial functions as a framework for organizing knowledge and techniques in the field. Managing is defined here as the creation and maintenance of an internal environment in an enterprise where individuals, working together in groups, can perform efficiently and effectively towards the attainment of group goals. Managing could, then, be called ""performance environment design."" Essentially, managing is the art of doing, and management is the body of organized knowledge which underlies the art.
Each of the managerial functions is analyzed and described in a systematic way. As this is done, both the distilled experience of practicing managers and the findings of scholars are presented., This is approached in such a way that the reader may grasp the relationships between each of the functions, obtain a clear view of the major principles underlying them, and be given the means of organizing existing knowledge in the field.
Part 1 is an introduction to the basis of management through a study of the nature and operation of management principles (Chapter 1), a description of the various schools and approaches of management theory (Chapter 2), the functions of the manager (Chapter 3), an analytical inquiry into the total environment in which a manager must work (Chapter 4), and an introduction to comparative management in which approaches are presented for separating external environmental forces and nonmanagerial enterprise functions from purely managerial knowledge (Chapter 5)…”
