"According to the dictionary, to administer is to govern, or to manage a public or private business. It means, therefore, to seek to make the best possible use of the resources available in achieving the goal of the enterprise. Administration includes, therefore, all the operations of the enterprise. But as a result of the usual way of organizing things to facilitate the running of the business, a certain number of activities constitute the special departments; the technical department, the commercial department, the financial department, etc., and the scope of the administrative department is found to be reduced accordingly."
