What is "Management"? What Do Managers Do?

There are a variety of views about this term. Traditionally, the term "management" refers to the set of activities, and often the group of people, involved in four general functions, including planning, organizing, leading and coordinating activities (the four functions are highly integrated).
Some writers, teachers and practitioners assert that the above view is rather outmoded and that management needs to focus more on leadership skills, e.g., establishing vision and goals, communicating the vision and goals, and guiding others to accomplish them.
