Review of the application of social network analysis (SNA) in construction project management research

Over the past two decades, social network analysis (SNA) has elicited increasing attention in construction project management (CPM) research as a response to the emerging perspective of viewing projects as network-based organizational organizations. However, a thorough review of SNA application in CPM research is unavailable. This study aims to address this gap by reviewing 63 SNA papers published in eight peer-reviewed journals from 1997 to 2015 to ascertain the status of this research area and identify future research directions. The papers are analyzed in terms of institutional and individual contribution, citations, topic coverage and research design and methodologies. Three research directions, namely, internal stakeholder networks for outcome-related values, external stakeholder networks for process-related values, and external stakeholder networks for outcome-related values, are identified. The findings of this study are believed to provide useful references for the future application of SNA in CPM research. (C) 2016 Elsevier Ltd. APM and IPMA. All rights reserved.
