The impact of team-member exchange, differentiation, team commitment, and knowledge sharing on R&D project team performance

This paper integrates team-member exchange (TMX), affective commitment, and knowledge sharing to examine how work unit TMX influences employees' R&D project team commitment and intention to share knowledge, and how team knowledge-sharing intention and TMX differentiation influences team performance. The results support the relationships between work unit TMX and employees' intention to share knowledge and team commitment. In addition, the results show that work unit TMX increases intention to share knowledge through increasing group members' team commitment. At the group level, the results support the relationships between team knowledge-sharing intention and team performance. The results also show that TMX differentiation moderates the relationship between work unit TMX and team performance. That is, greater work unit TMX is more likely to achieve higher team performance in a team with low TMX differentiation as opposed to a team with high TMX differentiation. Implications for theory building, future research, and R&D management are discussed.
