This study focuses on evaluating the situation of e-procurement institutionalization in the construction industry under three perspectives including internal organization, operational clusters, and industrial supports. Data collected by in-depth structured interviews with key managers from within a sample of 31 Vietnamese construction firms was analyzed to assign weights to measures through the AHP technique. The results can be used by business managers to build an effective action plan toward e-procurement sophistication and by government policy makers to formulate targeted supportive programs for e-procurement in the Vietnamese construction industry.
