Managers as the primary facilitator of organizational effectiveness (OE) through his/her actions and behavior, are responsible for developing and maintaining effective organizations. OE means different things to different people but takes a multidimensional approach in achieving its goals. The present research investigates the impact of organizational structure and leadership style on OE. Therefore, 47 managers were randomly drawn from a tall and large hierarchical structure and 34 were from the small and flat organization. A 46-item scale (Daftuar, 1983) measuring 9 dimensions of OE and a 14-item questionnaire of leadership style, were the tools of data collection. Analysis by t-test revealed a significant improvement in OE under small and flat hierarchical structure. Comparisons between groups showed that managers in small and flat structure organizations emphasized significantly more, the role of job involvement, innovation and need for involvement in maintaining effective organizations. Further comparisons between two types of organizations in terms of directive leadership style revealed that managers in small and flat organization gave significantly more importance to job involvement, self control, innovation and need for involvement. Moreover, as compared to their counterparts, managers using free-rein style of leadership promote more consensuses in small and flat organizations. Significant differences were not obtained for consultive type of leadership style in both the organizations. Findings of the present research provide support to the much-observed trend in the corporate world of today, which seems to favor the small and flat hierarchy in maintaining organizations effectively.
