Kết quả thực nghiệm cung cấp các bằng chứng thống kê để hỗ trợ cho bảy giả thuyết liên quan đến các yếu tố bên ngoài ổn định, năng lực quản lý và thành viên năng lực. Các kết quả của giả thuyết thử nghiệm giả thuyết bốn từ chối liên quan đến các yếu tố của tổ chức hỗ trợ vì yếu tố này không phải là ý nghĩa thống kê trong SEM mô hình.For external stability, the hypothesis “The more stable the external environment the better the project performance” (H1) is supported. The hypothesis of manager competencies “The higher competencies of project manager the better the project performance” (H2) is supported. The results also support the hypothesis “The higher competencies of project team members the better the project performance” (H3). These confirm that the factors of external stability, manager competencies and member competencies had a positive and significant impact on project performance. These results provide confirmatory support to the success factors developed by Belassi and Tukel (1996).For the moderating influences of project characteristics, the hypothesis “The strength of relationship between project factors and project performance will be significantly influenced by the factors related to the project” (H5) is supported. This provides confirmatory support to the intervening effect of the project life cycles proposed by Belout and Gauvreau (2004).There are positive and significant correlations among the factors of external stability, manager competencies and member competencies. These results support the three hypotheses “The competencies of project manager will be significantly and positively correlated with the competencies of project team members” (H6), “The stability of external environment will be significantly correlated with the competencies of project team members” (H7), and “The stability of external environment will be significantly correlated with the competencies of project team members” (H8). These are the findings of this study.The hypothesis “The more support from the organization the better the project performance” (H4) is rejected. This indicates that the organizational support factor do not have any impact on project performance. The SEM results do not support three hypotheses “The support of organization will be significantly correlated with the competencies of project manager” (H9), “The support of organization will be significantly correlated with the competencies of project team members” (H10), and “The stability of external environment will be significantly correlated with the support of organization” (H11). These stated that organizational support factor do not have any correlation with the factors of external stability, manager competencies and member competencies.8.4 SummaryThis chapter examines the direct relationships between the key project factors and project performance as well as the relationships among the key project factors as shown in conceptual framework. These relationships were analyzed by Structural Equation Modeling (SEM) techniques with the application of LISREL computer software. This analysis indicated that three key project factors including External Stability, Manager Competencies and Member Competencies demonstrate a significant influence upon Project Performance. Only the Organizational Support factor was not statistically significant. The results also indicated that the correlations among the key project factors of External Stability, Manager Competencies and Member Competencies were statistically significant. Again, the Organizational Support factor did not correlate with other key project factors. The hypothesis testing based on the SEM results indicated that seven hypotheses related to the factors of External Stability, Manager Competencies and Member Competencies were supported and four hypotheses related to the factor of Organizational Support were rejected. The next chapter will present the main findings and contribution of this study. It will also present the implications and the limitations of research results. CHAPTER 9 CONCLUSIONS AND RECOMMENDATIONS9.1 IntroductionThe overall objective of this study was to develop a conceptual framework to determine what are the important factors in project management success.
