Abstract
Studies of network effectiveness in the collaborative public program setting commonly have found that actors with more organizational partners, more indirect (bridging) ties to other partners, and more cohesive relationships among partners have greater success in implementing projects. This article contributes to this literature by developing and testing hypotheses about how strength of relationships, measured by frequency of contacts, moderates these results. In the context of community water supply projects in Nepal, the article shows that greater frequency of contacts between communities and organizational partners enhances the impact of having more partners and more cohesive relationships among partners but decreases the impact of having more indirect connections. For practitioners and network theorists, these findings highlight the importance of strength of relationships in the link between networks and performance.
