Management control has to do with management function aimed at achieving defined goals within an established timetable, and usually understood to have three components which include; setting standards, measuring actual performance, and taking corrective action. Management Control according to Wikipedia definition is one of the managerial functions like planning, organizing, staffing and directing. It is an important function because it helps to check the errors and to take the corrective action so that deviation from standards are minimized and stated goals of the organization are achieved in a desired manner. According to modern concepts, control is a foreseeing action whereas earlier concept of control was used only when errors were detected. Control in management means setting standards, measuring actual performance and taking corrective action.
