To bridge or to bond? Diverse social connections in an IS project team

Although research has shown that knowledge sharing among project team members is crucial for project performance, achieving knowledge sharing is still challenging. This problem is especially salient in IS project teams. Such teams are temporary organizations that may not progress through the necessary team formation cycle, yet are expected to produce intangible outcomes in a limited time. In this paper, we investigate how bonding and bridging social capital influence knowledge sharing and project performance. Bonding could facilitate cohesiveness within a team and lead a team to achieve project goals. Bridging could facilitate access to various beneficial resources beyond the boundary of a project team, increasing creativity and innovation. However, bridging is costly and can obstruct project performance. Our findings suggest that team members with high bonding social capital are more likely to share their knowledge with their team. Bonding and intention to share knowledge also positively affect project performance. Conversely, bridging social capital can contribute to project performance only through the mediating effect of bonding. This research contributes to theory by empirically examining the two types of social capital and their interdependence, as predictors of knowledge sharing and subsequently project performance. Project managers should form teams composed of members with diverse social connections and consider the balance between bonding and bridging within a team to control the potential disadvantageous effects of bridging social capital.

► The effect of external and internal social capital in the context of IS projects are examined.
► Bonding social capital positively affect knowledge sharing among team members and project performance.
► Bridging social capital has an indirect (via bonding social capital) effect on project performance.
