| Abstract: | This longitudinal study investigates changes in top management teams of a cohort of firms established in an emerging, high growth industry-the minicomputer industry. Given the turbulent conditions that organizations in this industry must contend with, top management teams do not remain stagnant. Most firms in the industry require a new set of executives to bring forth the organizational changes necessary to cope with major shifts in the environment.Little consensus exists in the literature on the impact of new executives on organizational performance. Studies have found that executive succession may be either positively, negatively, or unrelated to subsequent organizational effectiveness. The authors argue that a weakness of the existing research stream is a failure by scholars to adequately consider either the characteristics and skills of newly appointed executives or the patterns of change in management characteristics over time. The authors propose that organizational performance implications of executive succession events can be clarified by examining who the newly recruited executives are.When executive replacements are made, new successors often have characteristics which widely deviate from those of their predecessors. Such deviations in top management characterisics are shown to be pronounced where top management changes are made in response to crisis. In crises, successors are apparently recruited in an attempt to compensate for the shortcomings of their predecessors. However, while both high and low performing organizations make executive replacements as they evolve, the types of top management revisions they make differ. This study provides evidence that the types of senior management team changes made and the characterisics of newly recruited top management are related to organizational performance. High performing firms recruit new top management with new skills that are appropriate to the evolving environment. Lower performing firms somehow replace executives in response to crises, but seem to make the wrong executive recruitment decisions, apparently because the successors in the lower performing organizations do not match the changing competitive conditions in the industry. Low performing firms appear to recruit executives that entirely lack the types of top executive expertise are necessary for new environmental conditions.Although the majority of minicomputer firms required sizable changes in their executive teams over time, a small but significant subgroup of exceptional firms were identified that defy conventional wisdom. These extraordinary organizations were led by visionary CEOs—capable of maintaining management team stability as they successfully repositioned their firms' strategies to cope with continual environmental change. Among the conventional theories that these exceptional managers defy are: 1. Firms in high growth industries can be highly successful even if they retain their CEO/ Founders well beyond the embryonic stage. 2. Firms in high growth industries can retain a significant proportion of management ownership and still grow exponentially without financial crises. 3. Firms in high growth industries can maintain a high level of insider recruitment and still not become inbred.There appear to be two entirely distinct patterns of CEO/executive team success:Pattern 1 involves firms with no CEO change. This visionary CEO tends to be a founder who appears to be able to systematically recruit a limited number of external recruits in the top management team, selecting recruits who fit a changing environment yet also making maximum use of the existing team's longstanding experience and relationships. To maintain the necessary external perspective and avoid an inbred mindset, these firms a) tend not to allow the CEO to also be chairman, b) encourage a modest level of external ownership.Pattern 2 involves firms in which there is extensive turnover in both CEO and senior management teams, once again bringing in the kind of skills needed to match the changing environment. The CEO tends also to be chairman, and the external perspective is provided by having many external recruits plus low level of management ownership. |
