This article presents the “strategy diamond,” which extends received strategic management theory by integrating the positional view and the resource-based view, the formulation and implementation of strategy, and the firm’s internal selection environment into one relatively simple conceptual framework of dynamic forces driving firm evolution. The article suggests that this framework can be helpful in stimulating further research to drive towards a dynamic theory of strategy. The strategy diamond facilitates understanding the dynamic interplays between strategy logic and strategy execution, and its jargon-free “natural language form” may facilitate strategic conversations and help inculcate a strategic mentality into organizations. This framework has been useful for senior executives in two major corporations. Four case studies highlight how the framework may help instill strategic discipline in high-technology ventures operating in extremely dynamic environments.
