One of the most reprinted articles in the history of the Harvard Business Review, "The Core Competence of the Corporation" challenged and redefined traditional concepts of management strategy in an increasingly global and competitive market. Prahalad and Hamel base their 1990 argument on a comparison of case studies. They note that some corporations are adept at inventing new markets, quickly entering emerging markets, and shifting patterns of customer choice in established markets. The authors suggest that the ability to identify core competencies gives an essential competitive advantage, and they challenge managers to emulate these best practices, offering a blueprint to accomplish this.
