Is management a science and not an art?
Management is a science insofar as it utilizes statistics and proven methods. Management is an art insofar as it utilizes psychology and other social sciences in a limited way within a narrow range, with certain goals in mind. Managers are not career psychiatrists or anthropologists, but they can borrow and blend these disciplines with the "harder" numbers-based approaches to achieve great effect. The Legendary managers blend the best of both art and science. It is difficult to call management a pure science because it is hard to isolate every aspect of management using the scientific method to test and experiment and obtain repeatedly the same exact outcomes. Until human beings are replaced with robots or computers, management will have to tolerate a certain level of ambiguity, and therein lies the art of management.
