This paper explains that a leader is someone who can offer a compelling invitation for others to take action, while
managers
manage and
accomplish work through others. The author points out that today's leader needs a multitude of characteristics, but most important is the ability to develop a vision and to articulate it. The paper stresses that
managers often rely on their legitimate power or authority by very virtue of their position in the organization; leaders rely on other sources of power to accomplish their work.
