No advance in human knowledge will ever exclude the leader's need for the counsel of elemental human wisdom, and especially of collective wisdom, in … - James D. Mooney

The scalar principle is the same form in organization that is sometimes called hierarchical. But, to avoid all definitional variants, scalar is here preferred. A scale means a series of steps, something graded. In organization it means the grading of duties, not according to different functions, for this involves another principle of organization, but according to degrees of authority and corresponding responsibility. For convenience we shall call this phenomenon of organization the scalar chain. The common impression regards this scale or chain merely as a "type" of organization, characteristic only of the vaster institutions of government, army, church, and industry. This impression is erroneous. It is likewise misleading, for it seems to imply that the scalar chain in organization lacks universality. These great organizations differ from others only in that the chain is longer. The truth is that wherever we find an organization even of two people, related as superior and subordinate, we have the scalar principle. This chain constitutes the universal process of coordination, through which the supreme coordinating authority becomes effective throughout the entire structure.

The fact that functions may not be separated in organization does not in any way way destroy their identity as functions... The ideal of organized efficiency is not the complete segregation but the integrated correlation |of the three primary functions... The organizer must identify these functional principles, as they appear in every job, and make them the basis of his correlation... his duty is to correlate functions as such... The duty of the manager is to correlate who performs these functions... Management however represents the scalar principle... perpendicular correlations... true horizontal correlation requires other contact... The dissemination of understanding... of common purpose, of the relation of individuals to that purpose & to each other.

Organization begins when people, even if they be only two or more, combine their efforts for a given purpose. We have shown this by the simple illustration of two people uniting their efforts to lift and move some weighty object. This combination, however, is not the first principle of organization. It is only an illustration of organization itself. To find the first principle, let us carry the illustration a step further. The efforts of these two lifters must be coordinated, which means that they must act together. If first one lifted, and then the other, there would be no unity of action, and hence no true organization of effort. Here then we find the first principles of organization.
