A person can be a manager; a person is not a leader or neither. A manager focuses on monitoring results, comparing them with goals and correcting deviations.
But the leader focuses on stimulating people to overcome bureaucratic hurdles to help reach goals.
Managers and leaders differ in how they create an agenda to develop a rationale for achieving the agenda and execute plans and in the types of outcomes they achieve.
Although leaders and managers are related, there is some distinction between leaders and managers.
The overall success of any organization depends on the efforts of both leader and manager.
A leader in conjunction with a manager can produce orderly changes, can keep the organization properly aligned with its environment.
So the difference between manager and leader;
The manager administers; the leader innovates.
The manager is a copy; the leader is an original.
The manager maintains; the leader develops.
The manager accepts reality; the leader investigates it.
The manager focuses on systems and structure; the leader focuses on people.
The manager relies on control; the leader inspires trust.
The manager has a short-range view; the leader has a long-range perspective.
The manager asks how and when; the leader asks what and why.
The manager has his or her eye always on the bottom line; the leader has his or her eye on the horizon.
The manager imitates; the leader originates.
The manager accepts the status quo; the leader challenge sits.
The manager is the classic good soldier; the leader is his or her person.
The manager does things right; the leader does the right thing.
We can say, ‘A manager is a leader but a leader may not always be a manager’.
This comment is true because a leader is a developer and original characteristics of an organization. He maintains all of the organization. So he may not be a manager
