Collaboration strategy for ODA project using social network analysis

Abstract

Recently, Official Development Assistance (ODA) projects are increasing. Since ODA projects are financially stable, engineering companies planning to enter the international construction market need to make ODA projects as a first step. Engineering ODA project evaluates bidders by Quality Cost Based Selection (QCBS) method. Under the QCBS, companies make up for their lack of capacity through collaboration. Therefore, collaboration network information is required for winning. In this study, Social Network Analysis (SNA) is performed using the bidding information of socialbase, road, and water sector provided by World Bank (WB) for Vietnam ODA projects. The objectives of this study is to identify the network characteristics of the three sectors with the network shape and the density calculated through SNA, and to identify the main player by degree centrality and betweenness centrality, and to suggest an appropriate strategy. This is helpful information for decision makers when deciding whether to go overseas or not.
