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 principled.

The reason for the phenomenon we call organization is as fundamental as human life itself. It has its roots in the fact that man, in every fibre of his being, with the full force of every motive he has brought with him through the ages, is stamped indelibly as a social creature.

By the term functionalism, considered as a principle of organization, we mean the differentiation or distinction between kind of duties. Thus it is clearly distinguished from the scalar principle, in which there is also differentiation, but of quite another kind. The scalar differentiation refers simply to degrees or gradations of authority.
