The Nature of Leadership

3. How do leaders influence and move their followers to action?

Leaders hold a unique position in their groups, exercising influence and providing direction. Leonard Bernstein was part of the symphony, but his role as the New York Philharmonic conductor differed dramatically from that of the other symphony members. Besides conducting the orchestra, he created a vision for the symphony. In this capacity, leadership can be seen as a differentiated role and the nucleus of group activity.

Organizations have two kinds of leaders: formal and informal. A formal leader is that individual who is recognized by those outside the group as the official leader of the group. Often, the formal leader is appointed by the organization to serve in a formal capacity as an agent of the organization. Jack Welch was the formal leader of General Electric, and Leonard Bernstein was the formal leader of the symphony. Practically all managers act as formal leaders as part of their assigned role. Organizations that use self-managed work teams allow members of the team to select the individual who will serve as their team leader. When this person's role is sanctioned by the formal organization, these team leaders become formal leaders. Increasingly, leaders in organizations will be those who "best sell" their ideas on how to complete a project – persuasiveness and inspiration are important ingredients in the leadership equation, especially in high-involvement organizations.

Informal leaders, by contrast, are not assigned by the organization. The informal leader is that individual whom members of the group acknowledge as their leader. Athletic teams often have informal leaders, individuals who exert considerable influence on team members even though they hold no official, formal leadership position. In fact, most work groups contain at least one informal leader. Just like formal leaders, informal leaders can benefit or harm an organization depending on whether their influence encourages group members to behave consistently with organizational goals.

As we have noted, the terms leader and manager are not synonymous. Grace Hopper, retired U.S. Navy admiral, draws a distinction between leading and managing: "You don't manage people, you manage things. You lead people". Informal leaders often have considerable leverage over their colleagues. Traditionally, the roles of informal leaders have not included the total set of management responsibilities because an informal leader does not always exercise the functions of planning, organizing, directing, and controlling. However, high-involvement organizations frequently encourage their formal and informal leaders to exercise the full set of management roles. Many consider such actions necessary for self-managing work teams to succeed. Informal leaders are acknowledged by the group, and the group willingly responds to their leadership.
