The manager assigns various roles and responsibilities to the respective subordinates according to their pre-assigned designations.If the manager of any organization or business manages a considerably large number of employees or subordinates, then the span of control is wide and if there are relatively fewer number of subordinates or employees working under the manager,it is known as narrow span of control.In this instance, as an assistant director of the HIM department, Cynthia has been assigned the responsibilities and duties mentioned in the question based on their occupational designation.
