Leadership is a continuous process of influencing others to achieve goals. It deals with vision while management deals with structure and systems. There are different theories and styles of leadership. Charismatic theory sees leadership as innate qualities while trait theory sees it resulting from behaviors, skills and experience. Situational theory proposes that leadership style depends on the situation. Behavioral theory focuses on task-related and group-related leader functions. Leadership styles include power-orientation, varying levels of autonomy for subordinates, and consideration of people versus concern for production. Effective leadership combines the appropriate style with followers' maturity levels.
