The functions of management uniquely describe managers' jobs, as well as the specific actions managers, must take in order to perform their job. The most commonly cited functions of management are planning, organizing, leading, directing, and controlling, although some identify additional functions. The functions of management define the process of management as distinct from accounting, finance, marketing, and other business functions. These functions provide a useful way of classifying information about management, and most basic management texts since the 1950s have been organized around a functional framework, although growing criticism of this framework has been present, especially since the 1980s.
