Because one is an executive does not necessarily mean that he or she is a leader the former status rests on position, the latter on function. Barnard defines leadership as "the power of individuals to inspire cooperative personal decisions by creating faith," or, "the quality of behavior of individuals whereby they guide people or their activities in organized effort." Since Barnard maintains that executive capacity in the form of leadership is the most important strategic factor in human cooperation, a major task of the organization is to see that those in executive positions are indeed leaders.
