Leadership plays a key role in enabling organizational change. While management focuses on order and consistency, leadership concentrates on envisioning change and developing strategies to achieve the vision. Effective leadership involves realistically assessing the situation, considering stakeholders' needs, aligning people through communication, building coalitions, and motivating others. A leader's style should be tailored to the situation, with more directive approaches used when followers need development and participative leadership employed as they gain competence. Distributed and collective models of leadership are also important for enacting change across complex organizations.
