PurposePublic-Private Partnership (PPP) model still contains the obstacle in partnership, which can lead to different satisfaction between project participants. Therefore, project managers need to consider stakeholder satisfaction to ensure success in PPP implementation. However, this problem is limited in the previous studies in developing countries. The purpose of this study is to evaluate stakeholder satisfaction of PPP transport projects in developing countries.Design/methodology/approachA total of 15 satisfaction factors were identified and four main groupings were introduced by a review of the literature and expert interview rounds, including satisfaction of general public, satisfaction of private sector, satisfaction of government and satisfaction of end-users. A PPP expressway project in Vietnam was used to illustrate for this analysis. Data were collected through a questionnaire survey with 31 validated responses. The fuzzy synthetic evaluation method was then applied to evaluate satisfaction index for the stakeholder satisfaction of PPP transport projects in Vietnam as a developing country.FindingsThe analyzed result showed that the project participants are basically satisfied with gained outcomes of the experimental project with the satisfaction index = 3.46. Specifically, the general public expressed that they are “satisfied” with satisfaction index = 4.08. Meanwhile, end-users, government and private sector are “basically satisfied” with the project outcome (the satisfaction index of 3.31, 3.16 and 3.04, respectively).Originality/valueThis study provides more depth understanding of the satisfaction factor with transport infrastructure service in developing countries through PPP procurement. In addition, the decision-makers might utilize this evaluation model for rating the stakeholder satisfaction of real PPP projects to ensure project success.

The purpose of this study is to evaluate a quantitative driving index for implementing green building in Vietnam as a case study in developing countries. Using literature review and expert interviews, 19 driving forces affecting green building implementation were identified in the Vietnamese context. Via obtained data from a questionnaire survey, four principle factors were grouped from defined drivers. The fuzzy synthetic evaluation method was utilized to develop a driving index (DI) for developing the green building in Vietnam. DI model indicated that environmental impact is the most crucial group for green building implementation in Vietnam. Apart from this, the result of the comparative analysis also indicated that most driving forces for adopting green building in developing countries related to environmental and social problems. These results provide the decision-makers with a comprehensive tool to assess the expectations for green building implementation in both Vietnam and other developing countries.
