A coevolutionary perspective on knowledge strategy is developed, where variant positions in knowledge space are predicted to result in differential advantages in product space. In particular, advantages to being both consistent and specialized in knowledge space are predicted to generate advantages in product space. Results in support of this prediction are found in an analysis of the history of the computer industry. The theory advanced has implications for both technology strategy and for researchers interested in introducing choice to evolutionary models of organizations. In particular, the findings imply that exploration occurs at the population level among individually-focused knowledge specialists.
