According to skillsyouneed.com, leadership is not the same as management although it is possible to be both. Managers plan while leaders have a vision. Leadership asks what and why and empower others while managers ask how and work with the processes and systems.
There is a chart that shows the differences between a manager and a leader:
A manager administers; a leader innovates
A manager maintains; a leader develops
A manager focuses on systems and structure; a leader focuses on people and emotions
A manager controls systems and people; a leader inspires people
A manager accepts the way things are; a leader challenges the way things are
A manager has a short-range view; a leader has a long-range perspective
A manager manages tasks; a leader leads people
Leaders are more apt to take risks. Sometimes the roles of leaders and managers are blurred but there are definite differences.
