Corporate strategic reorientation and adjustment: A longitudinal analysis of the effects of top management teams

The impact of executive cognitive bases and values on corporate strategic change was examined in a longitudinal study of the computer hardware industry. Corporate strategic change was separated into pattern and magnitude dimensions as suggested by Ginsberg (1988). These dimensions complement the logic of Tushman and Romanelli (1985) who suggest that organizations proceed through long periods of stability or adjustment, punctuated by periods of metamorphic change or reorientation. I proposed that executive cognitive bases and values would be associated with strategic reorientation but not strategic adjustment since executive perceptions and responses are the internal driving forces that direct and redirect organizations (Romanelli & Tushman, 1988). Panel data analysis techniques were used to test the hypotheses developed in this study. Corporate strategic reorientation and adjustment were operationalized by changes in unrelated and related diversification, and changes in between-stage and within-stage vertical integration, respectively. The mean organization tenure and functional background heterogeneity of top management teams were used as proxies for executive cognitive bases and values. Results provided overall support for the hypotheses. Mean organization tenure was negatively related to unrelated diversification change, while neither mean organization tenure nor functional background heterogeneity were associated with related diversification change. Functional background heterogeneity was positively related to between-stage vertical integration change, however, contrary to expectations, it was negatively related to within-stage vertical integration change. These findings confirm and extend the literature which relates managerial characteristics to strategic change.
