"Organizations endure, however, in proportion to the breadth of the morality by which they are governed. Thus the endurance of organization depends upon the quality of leadership; and that quality derives from the breadth of the morality upon which it rests."

“Formally this work is divided into four parts, but in a sense it consists of two short treatises. One is an exposition of a theory of cooperation and organization and constitutes the first half of the book. The second is a study of the functions and of the methods of operation of executives in formal organizations.”

“Effectiveness relates to the accomplishment of the cooperative purpose which is social and non-personal in character. Efficiency relates to the satisfaction of individual motives and is personal in character.”

“When a specific desired end is attained we shall say that the action is "effective." When the unsought consequences of the action are more important than the attainment of the desired end and are dissatisfactory, effective action, we shall say, is "inefficient." When the unsought consequences are unimportant or trivial, the action is "efficient.”

“More than the topography and cartography of organization would be necessary to understand the executive functions; a knowledge of the kinds and qualities of the forces at work and the manner of their operation would also be needed.”

“The overvaluation of the apparatus of communication and administration is opposed to leadership and the development of leaders. It opposes leadership whose function is to promote appropriate adjustment of ends and means to new environmental conditions, because it opposes change either of status in general or of established procedures and habitual routine. This overvaluation also discourages the development of leaders by retarding the progress of the abler men and by putting an excessive premium on routine qualities.”

“An organization comes into being when there are persons able to communicate with each other who are willing to contribute action to accomplish a common purpose. The elements of an organization are therefore communication; willingness to serve; and common purpose. These elements are necessary and sufficient conditions initially, and they are found in all such organizations. The third element, purpose, is implicit in the definition. Willingness to serve, and communication, and the interdependence of the three elements in general, and their mutual dependence in specifie cooperative systems, are matters of experience and observation.”
