The administrative function has many duties. It has to foresee and make preparations to meet the financial, commercial, and technical conditions under which the concern must be started and run. It deals with the organization, selection, and management of the staff. It is the means by which the various parts of the undertaking communicate with the outside world, etc. Although this list is incomplete, it gives us an idea of the importance of the administrative function. The sole fact that it is in charge of the staff makes it in most cases the predominant function, for we all know that, even if a firm has perfect machinery and manufacturing processes, it is doomed to failure if it is run by an inefficient staff.
