The GAO manager, in fulfilling his role as a teacher, provides systematic guidance to his subordinates according to their varying needs and abilities. The manager modifies this role as soon as he perceives a subordinate growing in knowledge and in skill. When manifestations of individuality and creativity begin to emerge and reflect increasingly mature and professional conduct, the manager invariably becomes more a source of information and inspiration and less a supervisor. Through the manager, each assignment gives a subordinate the opportunity for a maximum, intensive, educational experience.
