The team performance model states that a team’s performance is based on its structure, dynamics, and stage of development. The performance model can be stated as a formula. Team performance is a function of team structure + team dynamics + team development stage. 

You should realize that to have high levels of performance the team must have an effective structure for working together as a team, have good dynamic human relations, and develop its ability to work as a team. Teams face the systems effect: if any one of the components is weak, performance suffers.
