Leader = innovates, promotes change, focus on people, eye on the horizon, long term view, challenges the status quo, does the right thing
Manager = administrator, focus on systems, eye on the bottom line, short range view, accepts status quo, does things right
You will have to forgive me for making up games to amuse myself, but I enjoy going into any business and guessing after my experience whether the organization has a “leadership” team or a “management” team. You should try it - you would be surprised how much you can tell about the leaders in an organization, whom you will never meet, from the experience at their retail stores.
While games such as my cookie experience are obviously trivial and completely unfair in making a broad judgment on any individual or organization, there is a strong correlation between the leadership/management fulcrum and the client experience and, ultimately, the long-term success of any organization. To survive the 21st Century, I would argue we are going to need a new generation of leaders, not managers.
