What the Difference Between Leadership and Management?

Leadership Definition: Leadership is the building of motivation through individuals in aid of reaching a certain set of objectives. A good leader is someone who can lead to good results, by using what he has in the best way possible.
Management Definition: The process of dealing with and controlling a certain task or person/people.

Managers do things right, while leaders do the right things

(Bennis and Nanus, 1985)

Not all managers are leaders and, equally, not all leaders are managers

(Kotter, 1990)
Managers slow things down. Leaders spark the business to run smoothly and quickly. Managers talk to one another, write memos to one another. Leaders talk to their employees, talk with their employees, filling them with vision, getting them to perform at levels they didn’t think possible (Transformational Leadership). Then they simply get out of the way (Contemporary Leadership).
In simple terms, management is there to enforce organisations are stable, structured and working correctly by problem solving within what they already have. Leadership looks into what is outside of the organisation, trying to visualise the future and create changes to improve the organisation. Management meets current objectives, leaders set objectives for the future.
For the above to happen, both leadership and management need to be strong.
