This volume reviews and reinterprets the existing literature on leadership, power, and influence processes; and provides a theoretical basis for understanding the leadership process in formal organizations. Numerous cited studies demonstrate that leadership is always relative to the situation; e.g., the effective leader makes a significant contribution to group goal attainment, and the group repays him with leadership status and the esteem that accompanies accepted leadership. In addition to providing an understanding of such an exchange process, this book also explains how leaders can motivate groups to accept influence, describes the processes that underlie continued exertion of influence, and outlines the ways in which leaders can make unique contributions to group goal attainment.
