DIMAGGIO WALTER W. POWELL Yale University What makes organizations so similar? We contend that the engine of rationalization and bureaucratization has moved from the competitive marketplace to the state and the professions. Once a set of organizations emerges as a field, a paradox arises: rational actors make their organizations increasingly similar as they try to change them. We describe three isomorphic processes-coercive, mimetic, and normative-leading to this outcome. We then specify hypotheses about the impact of resource centralization and dependency, goal ambiguity and technical uncertainty, and professionalization and structuration on isomorphic change. Finally, we suggest implications for theories of organizations and social change. In The Protestant Ethic and the Spirit of capitalistfirms in the marketplace;competition Capitalism, Max Weber warned that the ra- amongstates, increasingrulers' need to control tionalist spirit ushered in by asceticism had their staff and citizenry; and bourgeois de- achieved a momentum of its own and that, mands for equal protection under the law.
