Organization is as old as human society itself. - James D. Mooney

My own principal interest lies in the sphere of , which of all major forms of human organization is, in its present magnitude, the most modern. For this the reason is evident. The vast present-day units of industrial organization are products mainly of one creating factor, namely the technology of mass production, and this technology, born of the industrial revolution, has been almost exclusively an evolution of the last century. In contrast other major forms of human organization — the state, the church, the army — are as old as human history itself. Yet if we examine the structure of these forms of organization we shall find that, however diverse their purposes, the underlying principles of organization are ever the same.

Although a separate function of some kind is implicit in the very existence of a separate department, there may be, especially in manufacturing procedure, certain general functions, appearing in some form of departments, which in turn may require organized supervision and correlation. Thus we have cross-functionalism.

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 the making of all important decisions.
