This document reviews three schools of thought on what sources are likely to be the source of business success: the resource-based view, competence-based view, and dynamic capabilities view. It also discusses criticisms of the resource-based view, which is the most widely used model. Specifically, it outlines 13 criticisms of the resource-based view's VRIO framework, including that it does not fully explain how resources create strategic value and that the framework is not implementable in practice. The document concludes that resources alone cannot create competitive advantage and that dynamic capabilities need to be designed and continuously improved to achieve new advantages.
