What is the difference between leadership and management?

In an article in the Harvard Business Review, John Kotter (2013) expresses his frustration with the unclear distinction between what a leader is and what a manager is. Leadership does not depend on attributes, but on behavior. Leadership is accordingly not a reflection of hierarchical emplacement, but also ones ability to bring an organization into the future, and to be a visionary, to empower one’s employees and be capable of creating change.

Kotter (2013) explains that management is focused on well-known processes, planning, and budgeting with a general emphasis placed on administrative tasks.
