The purpose of the study is to enhance our understanding of the relationship among trust, commitment, and knowledge sharing in project teams. We examine how trust directly and indirectly affects knowledge sharing. We include two different foci of commitment that are highly relevant to project teams: team commitment and project commitment. A mediation analysis is conducted on data from 179 project team members in 31 Norwegian construction project teams. Our results suggest different effects of the two foci of commitment, indicating that, in a project team context, project commitment is more important for knowledge sharing than team commitment.
