Replication, a familiar phenomenon sometimes referred to as the "McDonalds approach," entails the creation and operation of a large number of similar outlets that deliver a product or perform a service. Companies pursuing this strategy are now active in over 60 industries. Although replicators; are becoming one of the dominant organizational forms of our time, they have been neglected by scholars interested in organizations. As a result of this neglect, replication is typically conceptualized as little more than the exploitation of a simple business formula. Such a view clouds the strategic subtlety of replication by sidestepping the exploration efforts to uncover and develop the best business model as well as the ongoing assessment that precedes large-scale replication of it. Empirical evidence supports an alternative view of replication strategy as a process that involves a regime of exploration in which the business model is created and refined, followed by a phase of exploitation in which the business model is stabilized and leveraged through large-scale replication. In this paper we present the key elements of a theory of replication strategy. We discuss key aspects of a replication strategy, namely the broad scope of knowledge transfer and the role of the central organization, and the analytical concepts of template and Arrow core as a preamble for specifying hypotheses about the conditions under which a replication strategy is more likely to succeed in a competitive setting. Replication strategy provides unusually transparent examples of the process of leveraging knowledge assets; we exploit this in our concluding discussion.
