The leader-member exchange originated from the three additional perspectives which is the one of the five approaches to leadership. This model was introduced George Graen and Fred Dansereau. They stated “Leader-member exchange model of leadership emphasizes that the leaders have different sorts of relationships with different subordinates.” (Williams, 2013) The reason why this approach to leadership is different from the others is because it focuses on the quality of the relationship between the leader and their followers. Everyone in a sports team has experienced certain type of bond between their coaches and player. The LMX model has divided relationship in to two groups; the in-group and out-group exchange.
