According to L.D. White, "Public administration consists of all those operations having for their purpose the fulfillment or enforcement of public policy."
In the words of Woodrow Wilson, "Public administration is detailed and systematic application of law. Every application of law is an act of administration."
According to Pfiffner, "Public administration consists of doing the work of the Government, whether it be running an X-ray machine in a health laboratory or coining money in the mint.... Administration consists of getting the work of Government done by co-ordinating the efforts of people so that they can work together or accomplish their set tasks. Administration embraces activities which may be highly technical and specialised, as public health and the building of bridges. It also involves managing, directing, and supervising the activities of thousands, even millions of workers so that some order and efficiency may result from their efforts."
An analysis of these and other definitions suggests that administration is an activity which demands correct analysis and accurate orientation to achieve the objectives of the organisations and meet the needs of the people in an economic and efficient manner. We can, thus, say that public administration is concerned with the implementation of public policy, as laid down by the competent authority economically and efficiently for the benefit of the people and the nation.
