5. Discussion: competency traps and dynamics of portfolio resources at Xerox
5.1. Competency traps Within the perspective of organizational ambidexterity as a dynamic capability, we shed light on the organizational dysfunctions that can compromise structural ambidexterity. We do so via the concepts of competency traps (Levitt & March, 1988), dominant logic (Prahalad and Bettis, 1986) and portfolio resources (Srivastava and Gnyawali, 2011). We also draw from the concept of dynamic capabilities, particularly the idea that an organization's processes, asset positions and historical paths can both enable but also constrain its ability to sense opportunities, seize them and reconfigure itself (Teece, 2007; Teece et al., 1997). When opportunities are seen to be consistent with existing organizational capabilities and configurations, top managers are likely to pursue them. If opportunities are seen to be outside the organizational core business, then the dynamic capabilities act as competency traps, constraining the pursuit of commercialization of technologies and ultimately strategic renewal. We find that dominant logic is related to the cognitive dimension of competency traps, disjointed inventions to the behavioral dimension, and inter-unit organizational tensions to the organizational dimension of competency traps.
