Defined in broadest terms, public administration consists of all those operations having for their purpose the fulfillment or enforcement of public policy. This definition covers a multitude of particular operations in many fields — the delivery of a letter, the sale of public land, the negotiation of a treaty, the award of compensation to an injured workman, the quarantine of a sick child, the removal of litter from a park, manufacturing plutonium, and licensing the use of atomic energy. It includes military as well as civil affairs, much of the work of courts, and all the special fields of government activity— police, education, health, construction of public works, conservation, social security, and many others.

Public administration is the use of managerial, political, and legal theories and processes to fulfill legislative, executive, and judicial governmental mandates for the provision of regulatory and service functions for the society as a whole or for some segments of it.

[ Public administration is merely] a special case of the larger category, administration, a process which is common to all organized human effort and which is highly developed in modern corporate business, in the church, in the Red Cross, in education, and in international bodies, public and private.

Public administration is the management of men and materials in the accomplishment of the purposes of the state.

Public administration is that part of the science of administration which has to do with government, and thus concerns itself primarily with the executive branch, where the work of government is done, though there are obviously administrative problems also in connection with the legislative and the judicial branches. Public administration is thus a division of political science, and one of the social sciences.

Public administration is a process or a theory, not merely an accumulation of detailed facts. It is Verwaltungslehre. The object of administrative study should be to discover, first, what government can properly and successfully do, and secondly, how it can do these proper things with the utmost possible efficiency and at the least possible cost both of money and of energy.

The Public Administration neither comprises nor heads any branch of government but is subordinate to all three of them. Like Congress, president, and courts, the Public Administration makes its distinctive contribution in a manner consistent with its peculiar place, which is one of subordination.

Administration has to do with getting things done; with the accomplishment of defined objectives. The science of administration is thus the system of knowledge whereby men may understand relationships, predict results, and influence outcomes in any situation where men are organized at work together for a common purpose. Public administration is that part of the science of administration which has to do with government, and thus concerns itself primarily with the executive branch, where the work of government is done, though there are obviously administrative problems also in connection with the legislative and the judicial branches. Public administration is thus a division of political science, and one of the social sciences.

The objective of public administration is the most efficient utilization of the resources at the disposal of officials and employees.

At the time of its initial publication, Public Administration helped to define this field of study and practice by introducing two major new emphases: an orientation toward human behavior and human relations in organizations, and an emphasis on the interaction between administration, politics, and policy. Without neglecting more traditional concerns with organization structure, Simon, Thompson, and Smithburg viewed administration in its behavioral and political contexts. The viewpoints they express still are at the center of public administration's concerns.

Historically, "public administration" has grown in large part out of the wider field of inquiry, "political science." The history of American political science during the past fifty years is a story much too lengthy to be told here, but some important general characteristics and tendencies it has communicated to or shared with public administration must be noted.

Public administration as an American profession originated in the early twentieth century with urban reformers advocating the application of scientific and business practices to rehabilitate corrupt city governments. That approach transformed governance in the United States but also guaranteed recurrent debate over the proper role of public administrators, who must balance the often contradictory demands of efficiency and politically defined notions of the public good. Currently the business approach holds sway. Legitimated by Al Gore's National Performance Review, the movement promotes entrepreneurs over civil servants, performance over process, decentralization over centralization, and flexibility over rules. John Rohr demurs, arguing that the movement goes too far in downplaying the distinctively American challenges arising from the separated powers principle. Consequently, the NPM alienates public management from its natural home -- a nation-state established within a constitutional order.

This is a study of the public administration movement from the viewpoint of political theory and the history of ideas. It seeks to review and analyze the theoretical element in administrative writings and to present the development of the public administration movement as a chapter in the history of American political thought.

Administration is the most obvious part of government; it is government in action; it is the executive, the operative, the most visible side of government, and is of course as old as government itself.
