Fiedler's contingency theory shows how a leader's orientation (task-focused or relationship-focused) impacts group performance under different situational conditions. The theory assesses the leader's orientation using the Least Preferred Co-worker scale, evaluates three factors of situational favorability, and determines which leader orientation is most effective for low, moderate, or high control situations. Specifically, it found that task-oriented leaders performed better in low and moderate control situations while relationship-oriented leaders performed better in moderate control situations.
