The concept of "management" is complex, and is defined as "controlling and organizing" (Longman English Dictionary Online); "conducting or supervising" (The Merriam-Webster Online Dictionary). Merriam-Webster further defines this as the "judicious use of means to accomplish an end." Koontz and Weirich (1988) state that management involves "designing and maintaining an environment in which individuals, working together in groups, accomplish efficiently selected aims." This definition is, however, inexact: it is not clear, for example, whether or not the "aims" are "accomplished efficiently" or "efficiently selected". Perhaps, in fact, the authors intend both meanings to apply. Drucker (2007) makes the point that management is about "people" and that it is essentially the "vision, dedication and integrity of managers that determine whether there is management or mismanagement."
