The Functions of the Executive[edit]
Main article: The Functions of the Executive
Barnard's classic 1938 book, The Functions of the Executive discusses, as the title suggests, the functions of the executive, but not from a merely intuitive point of view, but instead deriving them from his conception of cooperative systems.
Barnard summarized the functions of the executive as follows:
Establishing and maintaining a system of communication;
Securing essential services from other members;
Formulating organizational purposes and objectives.
