This article integrates two apparently incompatible models: Porter's competitive strategies model from the strategic management literature and world class manufacturing (WCM) from the operations management literature. The continuous improvement of the manufacturing function and its infrastructure can result in economies of scope and several types of competitive advantage not often considered possible under traditional strategic management and operations management paradigms. WCM's ability to master a firm's linkages is what makes the simultaneous achievement of lower cost and differentiation more widely possible than in the limited scenarios Porter suggests. Specifically, the article notes how a firm may be able to achieve a competitive position on several dimensions on which customers make purchasing decisions, thereby achieving an overall competitive advantage. WCM's focus on continuous improvement results in the competitive advantages of these firms escalating. This is consistent with D'Aveni's (1994) concept of hypercompetition. Thus, this article attempts to elaborate on Porter by noting how recent developments in operations management have expanded the set of firms able to achieve multiple competitive advantages from a few in specific industry niches to many firms which are able to develop certain manufacturing capabilities and corresponding linkages. A set of propositions is listed to guide research on multiple competitive advantages from the perspectives of both strategic management and operations management.
