Unpacking the “Black Box”: Understanding the Effect of Strength of Ties on Inter-Team Conflict and Project Success in Megaprojects

Megaprojects have been redefined as dynamic collaboration networks, which are characterized by the strength of the ties between teams. In China, megaprojects have long been criticized for low productivity, poor project implementation processes, and inter-team confrontation. Few studies in the construction domain have explored the relationship between the strength of ties, inter-team conflict, and project success. This research aims to investigate the relationship between the strength of ties, inter-team conflict, and project success in megaprojects. Strong ties and weak ties reflect the strength of ties. Inter-team conflict is measured by task-related conflict and relationship-related conflict. A questionnaire survey was conducted on Chinese megaprojects, and 306 questionnaires were collected. The data were analyzed by a structural equation model. The results indicate that strong ties positively impact task-related conflict while negatively impacting relationship-related conflict. Weak ties positively impact inter-team conflict. Task-related conflict and relationship-related conflict have positive and negative effects on project success, respectively. The effect of the strength of the ties on a project’s success is mediated by conflict. This study adds to existing research on the strength of ties and emphasizes the significance of megaproject network governance. The results reveal the constructive effects of the strength of ties and task-related conflict, as well as the non-constructive effects of relationship-related conflict. This provides a reference for megaproject managers to implement project governance.
