Abstract
Recent contributions to strategic management and the theory of the firm collectively known as the "resource-based view of the firm" provide illuminating insights into the sources of profitability and the nature of competitive strategy. This article argues that internal resources rather than the market environment should provide the foundation for a firm's strategy. On the basis of an analysis of the relationships among resources, capabilities, competitive advantage, and profitability, this article advances a framework for a resource-based approach to strategy formulation.
