The emergence of globalisation further contributed to this growth. Administration means ‘to serve’, or ‘to manage affairs’. In his article entitled “The Study of Administration”, published in 1887, he emphasized the need for studying Public Administration as a discipline apart from politics. It has also been found that many states are eager to take lessons from the UN agencies to renew and restructure their public administration. He emphati­cally said that in any public policy there may be controversy or political colour and this feature is very common. The credit for initiating as an academic study of Public Administration goes to Woodrow Wilson, who was teaching Political Science at Princeton University and who later became the President of USA. It is really an innovative scheme because, in his assessment, if a philosopher takes the burden of administration it would be the best administered state because the philoso­phers will rule the state without any consideration of their personal gain or loss. and who later became the President of USA. In this book Good-now drew a clear distinction between politics and administration. From the 1960s the evolution of public administration took a new turn and this turn is remarkable. EVOLUTION OF THE FIELD. The Hawthorne study is a landmark incident in the history of public administration. From the history of Western political thought we come to know that the Roman emperors (about 700 B.C.-400 A.D.) were good rulers (though they were dictators) because they ensured a better type of administration in several parts of the empire. Final Stage of Public Administration Evolution. OF PUBLIC ADMINISTRATION. While selecting a particular course of action the manager or the decision-maker must study all the possible consequences. The United States has survived and thrived through major cultural shifts, varying degrees of economic climates, and both civil and world wars. (It may be noted that the mention of particular year may not be agreed by all.) This is called the Human Relations approach to public administration and the following conclusions were drawn from the Hawthrone experiment: (a) Workers are not just like machines. With this the second stage of the evolution of public administration began. It was considered as a proverb and naturalistic facilities they criticized due to its depend on formal structure of organization. It has been observed by Nicholas Henry that the studies produced a new concept known as “Hawthrone effect”. But in real situation a body of well-trained staff is not available at all and that creates numerous problems for the management of state. A survey was conducted and it was found that a groundswell (a build-up of opinion in a large section) development had taken place. Period III (1938 – 1947) Era of challenge : The main theme during this period was the advocacy of ‘Human Relationship Behavioural Approach’ to the study of Public Administration. We can broadly divide the history of Public Administration into the following five periods:-. The evolution of public administration as a practice and discipline can be categorized into two major phases namely the traditional and modern phase. In antiquity the Egyptians and Greeks organized public affairs by office, and the principal officeholders were regarded as being principally responsible for administering justice, maintaining law and order, and providing plenty. This again did not affect the quantum of production that is as before the production began to increase. It was claimed by many that the public administration must be an overarching theory which will focus on all aspects—particularly the important ones of management. They have their own values and motives which guide them. This approach to organisational analysis drew attention to the formation and effect of work groups in the organisation, the force of informal organisation in the formal set-up… In short, the human relations approach brought out the limitation of the machine concept of organisation in scientific management thought”.
