- A leader is someone who can influence others and has managerial authority. Leadership is the process of leading a group to achieve goals.
- Early leadership theories examined traits and behaviors of leaders. Trait theories were unsuccessful at identifying universal leader traits. Behavioral theories identified three leadership styles and two dimensions of leader behavior: initiating structure and consideration.
- Contingency theories propose that effective leadership depends on matching a leader's style to situational factors. Fiedler's contingency model measured leader-member relations, task structure, and position power to determine if a task-oriented or relationship-oriented style would be most effective.
