Emergence and Evolution of Network Structures in Complex Interorganizational Project Teams

Abstract

Networks in complex interorganizational engineering project teams are shaped by individuals’ actions to perform specific project functions. These networks are dynamic; they change based on project needs, and each network structure influences the next. Particularly, this study examines how temporary knowledge-transfer networks in architectural, engineering, and construction (AEC) project teams emerge and evolve during project delivery, adopting different structures that are interdependent. We longitudinally analyzed the knowledge-transfer networks of an AEC project team with 79 to 102 members via statistical and qualitative analyses. Results showed that a core-periphery structure originally emerged in the project team network to support team coordination. Later, triangles among core and peripheral members emerged without disassembling the core-periphery structure and generating cohesive subgroups for deep knowledge transfers among team members. The findings shed light on the dynamic nature of knowledge-transfer networks in complex interorganizational project teams. Via informed network interventions, project managers can support knowledge-transfer structures that help improve team and project performance.
