Resource dependence theory (RDT) is the study of how the external resources of organizations affects the behavior of the organization. The procurement of external resources is an important tenet of both the strategic and tactical management of any company. Nevertheless, a theory of the consequences of this importance was not formalized until the 1970s, with the publication of The External Control of Organizations: A Resource Dependence Perspective (Pfeffer and Salancik 1978). Resource dependence theory has implications regarding the optimal divisional structure of organizations, recruitment of board members and employees, production strategies, contract structure, external organizational links, and many other aspects of organizational strategy.
The basic argument of resource dependence theory can be summarized as follows:
Organizations depend on multidimensional resources: labor, capital, raw material, etc. Organizations may not be able to come out with countervailing initiatives for all these multiple resources. Hence organization should move through the principle of criticality and principle of scarcity. Critical resources are those the organization must have to function. For example, a burger outlet can't function without bread. An organization may adopt various countervailing strategies—it may associate with more suppliers, or integrate vertically or horizontally.
Resource dependence theory is one of many theories of organizational studies that characterize organizational behavior. In many ways, resource dependence theory predictions are similar to those of transaction cost economics, but it also shares some aspects with institutional theory.
