All remaining errors are mine. Evolution of Fit: The Voyage of Vanguard Abstract: While firms have frequently been conceptualized as configurations of choices, the evolution of configurations has not received much attention. We start to develop a typology of evolutionary patterns by describing two developmental paths. Patch-by-patch development is characterized by managers’ sequential creation and elaboration of strategic themes, whereas thin-to-thick development consists of an early formulation of strategic themes and subsequent elaboration with supporting choices. A longitudinal study of The Vanguard Group illustrates a proposed approach to identifying the developmental pattern of a particular firm. Moreover, the study yields hypotheses concerning the relationship between the patterns and drivers of a firm’s development. Firms have been conceptualized as systems of highly interconnected choices in a variety of literatures (e.g., Miller, 1981; Milgrom and Roberts, 1990; Porter, 1996; Levinthal, 1997; Whittington, et al., 1999). In these analyses, firms’ choices with respect to activities, policies, organizational structures, capabilities and resources are seen to form complex interdependent systems. Yet firms are generally not born with fully elaborated interconnected systems. Hence, the question arises how these systems evolve over time.
