This paper examines similarities in service integration efforts and uses this information to develop a set of organizing principles and constructs for planning a service integration initiative. First, it elaborates on two key dimensions—relationship intensity and institutional similarity—critical for understanding any particular integration effort. Second, it proposes a strategy for framing integration efforts based on these two dimensions. Third, it considers the implications of this framework for developing an integration agenda. Finally, it identifies the basic components of all integration efforts within the context of a dynamic operating environment.
