The two dual concepts, leader versus manager, leadership and management, are not interchangeable, nor are they redundant. The differences between the two can, however, be confusing. In many instances, to be a good manager one needs to be an effective leader.
Many CEOs have been hired in the hope that their leadership skills, their ability to formulate a vision and get others to “buy into” that vision, will propel the organization forward.
In addition, effective leadership often necessitates the ability to manage—to set goals; plan, devise, and implement strategy; make decisions and solve problems; and organize and control. For our purposes, the two sets of concepts can be contrasted in several ways.

First, we define the two concepts differently. management is a process consisting of planning, organizing, directing, and controlling. Here we define leadership as a social (interpersonal) influence relationship between two or more people who are dependent on each another for goal attainment.
Second, managers and leaders are commonly differentiated in terms of the processes through which they initially come to their position. Managers are generally appointed to their role. Even though many organizations appoint people to positions of leadership, leadership per se is a relationship that revolves around the followers’ acceptance or rejection of the leader.8 Thus, leaders often emerge out of events that unfold among members of a group.
Third, managers and leaders often differ in terms of the types and sources of the power they exercise.

Managers commonly derive their power from the larger organization. Virtually all organizations legitimize the use of certain “carrots and sticks” (rewards and punishments) as ways of securing the compliance of their employees.
In other words, by virtue of the position that a manager occupies (president, vice president, department head, supervisor), certain “rights to act” (schedule production, contract to sell a product, hire and fire) accompany the position and its place within the hierarchy of authority.
Leaders can also secure power and the ability to exercise influence using carrots and sticks; however, it is much more common for leaders to derive power from followers’ perception of their knowledge (expertise), their personality and attractiveness, and the working relationship that has developed between leaders and followers.

From the perspective of those who are under the leader’s and manager’s influence, the motivation to comply often has a different base.
The subordinate to a manager frequently complies because of the role authority of the manager, and because of the carrots and sticks that managers have at their disposal.
The followers of a leader comply because they want to. Thus, leaders motivate primarily through intrinsic processes, while managers motivate primarily through extrinsic processes.

Finally, it is important to note that while managers may be successful in directing and supervising their subordinates, they often succeed or fail because of their ability or inability to lead.
As noted above, effective leadership often calls for the ability to manage, and effective management often requires leadership
