Linking Personality Trait Variance in Self-Managed Teams to Team Innovation

Researchers have suggested that some personality traits are associated with better team functioning when team members are homogeneous, whereas other personality traits improve team functioning when team members are heterogeneous. This article extends these ideas to team innovation and examines (a) how team variance in extraversion, agreeableness, openness, and conscientiousness relates to innovation in teams; and (b) how these relationships dynamically evolve over time. Our study included 704 surveys completed by 243 team members in 32 teams, at three time points. Results revealed that teams with less variance in extraversion showed higher levels of team innovation. For agreeableness and openness, we did not find main effects of team heterogeneity on team innovation. For teams with low heterogeneity in agreeableness, however, team innovation decreased over time. Team variance in conscientiousness was negatively associated with team innovation. Our findings provide support that team personality plays a role for innovation.
