Hackman's Team Effectiveness Model (1990) includes three key themes for an effective team, which are Real Team, Compelling Direction and Right People.
Real Team – A team which are reliable and have knowledge of people's strengths within the team.
Compelling Direction - should be clear, challenging, and consequential.
Right People - The right people should be on the team, people who have the same goals and objectives.
