The administrator is more like the engineer who constructs a power plant, that is, he is concerned with the realization of conscious human purposes b… - Charles A. Beard

Already, we may truly say, we have an enormous body of exact and usable knowledge in the domain of administration. It would be easy to list thousands of volumes and articles on the subject, from the hands of high competence. I have seen this body of literature grow from a few items in 1898 to an enormous mass in 1939. During this period I have seen the number of research workers increase from a mere handful to hundreds. This is a fact also, at least for informed and competent persons. During this period the opportunities for life work in administration have multiplied many times. I dare say, though I shall not try to prove it, that the body of exact literature in administration is many times larger than the body of exact literature in natural science when Bacon, Galileo, and Newton, began the revolution in natural science three hundred years ago. During this same period I have seen the number of societies and organizations among administrators, local and general, increase from nothing to fifty or sixty.

In other words, there are in administration things analogous to, if not identical with, the mechanical tracts or deterministic sequence, of physics. If, for example, it is decided by government to accomplish the purpose of providing compensation at given rates for men and women employed in industry who sustain injuries in connection with their occupations, the administrator can, like the engineer, estimate in advance the probable cost of such a design, indicate the types of officers and employees necessary to administer the design, and the administrative procedures appropriate to the whole process from beginning to end. And, as in the case of the hydro-electric engineer, the administrator, later sees the results of his operations and can compare them with his advance estimates. There are more variables and incalculables in human affairs than in hydroelectric affairs, but even so administration achieves pre-determined results with an approximation which is often amazing for its exactness. If administrative designs and estimates were not realized in practice with a high degree of exactness, both industry and government would collapse.
