Promoting collaboration in the architectural, engineering, and construction (AEC) industry, the innovative and contractually followed integrated project delivery (IPD) method has been instituted to increase the number of information sharing interactions among team members and improve team integration. However, project outcome effectiveness depends on not only the number, but also the quality, of these information exchange interactions. This paper posits that goal alignment in IPD project teams fosters the creation of reasoned and productive information sharing connections which enhance team members' ability to monitor key project-related information, impacting their tasks and ultimately project outcome effectiveness. To test this model, we surveyed 185 team members from 21 project teams that contractually followed IPD and analyzed data at the project team level. The model was first validated via a confirmatory factor analysis and then tested using path analysis. The results indicate that the effect of goal alignment on team members' perception of IPD effectiveness was mediated by monitoring in IPD project teams. If team members tie their goals, they make the effort to seek and search key information to accurately monitor project progress.
