The fundamental objective of the science of administration is the accomplishment of the work in hand with the least expenditure of man-power and materials. Efficiency is thus axiom number one in the value scale of administration. This brings administration into apparent conflict with certain elements of the value scale of politics, whether we use that term in its scientific or in its popular sense. But both public administration and politics are branches of political science, so that we are in the end compelled to mitigate the pure concept of efficiency in the light of the value scale of politics and the social order. There are, for example, highly inefficient arrangements like citizen boards and small local governments which may be necessary in a democracy as educational devices. It has been argued also that the spoils system, which destroys efficiency in administration, is needed to maintain the political party, that the political party is needed to maintain the structure of government, and that without the structure of government, administration itself will disappear. While this chain of causation has been disproved under certain conditions, it none the less illustrates the point that the principles of politics may seriously affect efficiency. Similarly in private business it is often true that the necessity for immediate profits growing from the system of private ownership may seriously interfere with the achievement of efficiency in practice.

What is the work of the chief executive? What does he do?
