| Summary: | 碩士 === 國立雲林科技大學 === 資訊管理系 === 107 === Project team such as information systems development or new product development are composed of cross-domain experts. Transactive Memory System (TMS) addresses how to leverage and combine the distributed knowledge across members to help the team maximize the value of their individual knowledge. Based on the Social Network Theory (SNT) and the TMS, this study conceptualizes the knowledge sharing network and the TMS as homogeneous and heterogeneous aspects, and empirically tests their effects on project efficiency and team innovation. This study collected 123 projects and applied the moderated regression analysis to test the proposed hypotheses. Results showed that task uncertainty positively moderated the relationship between the depth of homogeneous knowledge sharing networks and homogeneous TMS, while task uncertainty positively moderated the relationship between the breadth of heterogeneous knowledge sharing networks and heterogeneous TMS. Further, heterogeneous TMS has a higher effect on team innovation compared to homogenous TMS.
