"The ingenuity of the average worker is sufficient to outwit any system of controls devised by management."

“The key question for top management is what are your assumptions about the most effective way to manage people?”

“Every managerial act rests on assumptions, generalizations, and hypotheses — that is to say, on theory. Our assumptions are frequently implicit, sometimes quite unconscious, often conflicting; nevertheless, they determine our predictions that if we do a, b will occur. Theory and practice are inseparable.”

“The effectiveness of authority as a means of control depends first of all upon the ability to enforce it through the use of punishment. In the two organizations which have been the models for classical organization theory, the situation with respect to enforcement is clear. In the military, authority is enforceable through the court-martial, with the death penalty as the extreme form of punishment. In the Church, excommunication represents the psychological equivalent of the death penalty.”

“The approach that dominates organizational theory, teaching, and practice for most of the twentieth century looked at organizations from the top-down, starting with a view of the CEO as the "leader" who shapes the organization's strategy, structure, culture, and performance potential. The nature of work and the role of the workforce enter the analysis much later, after considerations of technology and organization design have been considered. However, if the key source of value in the twenty-first-century organization is to be derived from the workforce itself, an inversion of the dominant approach will be needed. The new perspective will start not at the top of the organization, but at but at the front lines, with people and the work itself — which is where value is created. Such an inversion will lead to a transformation in the management and organization of work workers, and knowledge. This transformation was signalled by McGregor, but we must go further.”

“We live today in a world which only faintly resembles that of a half century ago. The standard of living, the level of education, and the political complexion of the United States today profoundly affect both the possibilities and limitations of organizational behavior. In addition, technological changes are bringing about changes in all types of organization. In the military, for example, it is becoming increasingly difficult to manage a weapons team in the field as a typical infantry unit was managed a couple of decades ago. Such a team requires a high degree of autonomy. Instead of following explicit orders from superiors, it must be able to adjust its behavior to fit local circumstances within the context of relatively broad objectives. Underlying the principles of classical organization theory are a number of assumptions about human behavior which are at best only partially true.”

“Human behavior is predictable, but, as in physical science, accurate prediction hinges on the correctness of underlying theoretical assumptions. There is, in fact, no prediction without theory; all managerial decisions and actions rest on assumptions about behavior. If we adopt the posture of the ostrich with respect to our assumptions under the mistaken idea that we are thus “being ‘practical,” or that “management is an art,” our progress with respect to the human side of enterprise will indeed be slow. Only as we examine and test our theoretical assumptions can we hope to make them more adequate, to remove inconsistencies, and thus to improve our ability to predict.”
