It is what we think we know that keeps us from learning. - Chester Irving Barnard

Formally this work is divided into four parts, but in a sense it consists of two short treatises. One is an exposition of a theory of cooperation and organization and constitutes the first half of the book. The second is a study of the functions and of the methods of operation of executives in formal organizations.

It is important at this point to make clear that every coöperative purpose has in the view of each coöperating person two aspects which we will call (a) the coöperative and (b) the subjective aspect, respectively.

An organization comes into being when (1) there are persons able to communicate with each other (2) who are willing to contribute action (3) to accomplish a common purpose. The elements of an organization are therefore (1) communication; (2) willingness to serve; and (3) common purpose. These elements are necessary and sufficient conditions initially, and they are found in all such organizations. The third element, purpose, is implicit in the definition. Willingness to serve, and communication, and the interdependence of the three elements in general, and their mutual dependence in specifie cooperative systems, are matters of experience and observation.
