This study utilized Cameron's (1978) construct of organizational effectiveness to identify the relationship between the predictor variables of: (1) managerial strategy; (2) organizational culture; (3) change in the external environment; and (4) resource dependency, using causal modeling procedures. This construct is a theoretical framework that incorporates the use of multiple perspectives that can be recorded in relationship to one another. The study is based on a survey of 304 academic deans of American Assembly of Collegiate Schools of Business member programs for the United States and Canada. The findings suggest that internal organizational culture has the most important influence on organizational effectiveness, with some support for managerial strategy as a key indicator of effectiveness.
