Diversity, newcomers, and team innovation: The importance of a common identity

In this chapter, we introduce a theoretical model to explain under which conditions different insights or approaches within a team do not necessarily undermine team cohesiveness or prevent the development of a common team identity, and can in fact even reinforce each other. We will review a program of research that examined the formation of a common identity in new collaborations, as well as the extent to which teams accept newcomers who possess unique resources. We show that clarity and congruence determine the likelihood that team members will maintain a common identity while they effectively use the differences among them and accommodate to team changes.
