The data collected for these studies cannot imply causation. All data are cross-sectional and were analyzed using correlational statistics. Hence, any interpretations must be salted with caution. Further, other variables need to be assessed to verify the meaning of these correlational results. Other variables for future study include stage of development of the firm, the tenure of the top management team, the CEO in particular, the historical turnover of leaders and the centralization of power within the top management team. These variables cannot be assessed with a survey; they require different methods.
