Explain the importance of context and leadership as influences on team effectiveness.

The factors that influence team and group effectiveness are interrelated.Figure 12.3 identifies eight of the core factors: Context,leadership,goals,size,member roles,member diversity,norms,and cohesiveness.Each factor needs to be analyzed separately and in relation to each other.
The two factors that can impact all the other factors are context and leadership.The context refers to the external conditions within which a team works.Likewise,a leader often assumes a key role in the relations between the team and external groups,such as customers or suppliers,and often influences the selection of new members.
