This book undertakes the study of management by utilizing analysis of the basic managerial functions as a framework for organizing knowledge and tech… - Harold Koontz

Although students of management would readily agree that there have been problems of management since the dawn of organized life, most would also agree that systematic examination of management, with few exceptions, is the product of the present century and more especially of the past two decades.

Every organization structure, even a poor one, can be charted, for a chart merely indicates how departments are tied together along the principal lines of authority. It is therefore somewhat surprising to find top managers occasionally taking pride in the fact that they do not have an organization chart or, if they do have one, feeling that the chart should be kept a secret.

The Mathematical School ; Although mathematical methods can be used by any school of management theory, and have been, I have chosen to group under a school those theorists who see management as a system of mathematical models and processes. Perhaps the most widely known group I arbitrarily so lump are the operations researchers or operations analysts, who have sometimes anointed themselves with the rather pretentious name of "management scientists." The abiding belief of this group is that, if management, or organization, or planning, or decision making is a logical process, it can be expressed in terms of mathematical symbols and relationships. The central approach of this school is the model, for it is through these devices that the problem is expressed in its basic relationships and in terms of selected goals or objectives.
