Hackman Team Effectiveness Model

Hackman's Team Effectiveness Model (1990) includes three key themes for an effective team, which are Real Team, Compelling Direction and Right People.

Servant Leader

Servant Leadership (defined by Robert K Greenleaf in 1970) is based on the wish to serve, to provide support, guidance and motivation.

Tuckman

The model describes five stages (forming, storming, norming, performing and adjouring) of group development.

Lewin's Leadership Style

Lewin (1939) identified three different styles of leadership, which were Authoritarian (Autocratic), Participative (Democratic) and Delegative (Laissez-Faire).  Lewin concluded that the Democratic style was the most affective.

Styles of Power

French and Raven (1959) identified five styles of power which a leader may possess to have influence over their followers.  These  are reward, coercive, legitimate, referent and expert power.

Northouse outlined the qualities of a transformational leader as ‘empowering’, a strong role model with high values, a listener and one who helps the organisation by helping others contribute to it. The 'additive” effect of transformational leadership is pulling together, the team and ideas, to reach performance beyond expectations.
