Different structural, organizational, and managerial options greatly influence the role of evaluation. Evaluation serves different functions in organizations of higher and lower autonomy and likewise in progressive and reactive organizations. The role of the evaluator in the organizational hierarchy was dictated by the type of organization. In high autonomy, progressive organizations the evaluator was far removed from those on the production level. In low autonomy, reactionary organizations, the evaluators at times were the same individuals as those on the production level. Such organizational and managerial options had considerable influence on the resultant role and impact of evaluation in a given development effort. (Author/SM)
