Managing Interfaces in Large-Scale Projects: The Roles of Formal Governance and Partnering

Interface management has been viewed as one of the important organizational capabilities to promote coordination and integration among stakeholders in construction project delivery, especially for large-scale projects. This paper examines the role of formal governance, partnering, and organizational boundary activities and their interactions in interface management performance. An integrated framework with consideration of the influence of formal governance, partnering, and boundary activities on interface management performance and associated project outcomes was developed and empirically tested with data collected from 85 large-scale international projects. The results show that formal governance is the dominant determinant of interface management performance and can indirectly influence it through improving partnering and boundary activities. Partnering and boundary activities are also significant antecedents of interface management performance, which, in turn, improves project outcomes of large-scale construction projects. Formal governance and partnering mutually reinforce each other. Interface management performance is positively related to project outcomes in terms of quality, cost, and schedule. This empirical research contributes to the fundamental understanding of the critical factors that govern the interface management performance and, ultimately, the project outcomes. In addition, the outcomes of this study highlighted the broad managerial implications for participants in large-scale projects
