Following these two phases is a situational approach to leadership. Researchers turn their attention to the context in which leadership is exercised. Task-related and people-centred behaviours are interpreted differently by groups in different contexts. Researchers attempt to isolate specific properties of leadership situations that relate to the leader’s behaviour and performance. The fourth phase that includes linking the culture of the organization to the leader is encompassed in the transformational model of leadership. Instructional leadership and transformational leadership have been a topic of conversation and debate among scholars for the past decade. The current focus is linking leader behaviour with the organizational culture (Murphy, 2002).
