And if the experience of natural science is any guide, then as the science of administration advances, we may reasonably expect it to take on an incr… - Charles A. Beard

The administrator is more like the engineer who constructs a power plant, that is, he is concerned with the realization of conscious human purposes by the conscious use of human beings and materials. It is true that the mere student of administration may be just an observer, but he does not merely observe natural, unconscious, and automatic operations. He observes the formulation of human purposes, consciously and deliberately and operations designed to effect given results. And he sees calculations of results in advance realized later in practice with a high degree of approximation. The degree of approximation between advance calculations and results is not often, if ever, as exact as in the case of a hydro-electric plant, but it is constantly exact enough for practical purposes.

If I were compelled to state in a single sentence the most significant contribution of our movement to modern civilization, I should say that it is the application of the idea of continuous and experimental research, found so effective in economic enterprise, to the business of public administration intimately and in a deep-thrusting sense, a contribution to the processes by which modern mankind is striving with all its resources to emancipate itself from the tyranny of rules of thumb and the blind regimen of nature, becoming conscious of its destiny as an all conquering power.

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.
