• Functional types of leadership models focus on what the leader has to do. Unlike the Behavioural Ideals approach, Functional leadership models do not suggest ideal ways of behaving, nor do they match behaviours to circumstances like Situational/Contingency theory. Instead, Functional leadership models focus on the action areas that a leader must address to be effective. The most notable Functional models are John Adair's Action-Centred Leadership, and Kouzes & Posner's Five Leadership Practices.
