Abstract A developing stream of research in the strategy field explores the competitive structure of industries from the perspective of industry participants. This work has demonstrated that managers develop strategic group knowledge structures in order to make sense of their competitive environment. This study extends this line of research by examining the complexity evident in the strategic group knowledge structures developed by firms' top management teams and assessing the relationship between complexity in these knowledge structures and subsequent firm performance. Specifically, we examine the complexity of top managers' knowledge structures regarding their competition using a sample of 76 top management teams from banks in three U.S. cities. Using hierarchical regression, we find a significant relationship between the complexity of cognitive strategic groups and subsequent firm performance. These results suggest that the structure of the cognitive templates that top managers use to understand their environment and the actions of their competitor influence the degree of strategic success of their firm.

We distinguish novelty from newness and argue that the tasks of new venture top management teams vary with new venture novelty. We argue that as novelty increases, the information processing requirements on the TMT change as well. Because a team's demographic characteristics influence its information processing abilities, venture performance should reflect, at least partially, the fit between the characteristics of the TMT and the level of venture novelty. Evidence from a large sample of ventures supports this view.
