EVALUATION OF CONSTRUCTION PROJECT’S SUCCESS FACTORS

Purpose of this paper: This research aims to develop new approach to identify and evaluate the main factors, which affect construction project success. Methodology: Objectives of this research was achieved through the design of questionnaire to evaluate the importance of each factor by project management experts. After receiving 113 responses, the relative importance of each factor was calculated by the Sigma Level (L) concept and the weight of each factor was calculated according to the contribution of each factor to the total L summation. Questionnaire results was validated through several meetings with project managers and performing Paired test to confirm that there is no significant difference between project managers' opinion and the results of questionnaire. Findings: Results of questionnaire revealed that experts believe that top five factors are: Scope, Time, Quality, Cost & Stakeholders Management in descending order. Paired test confirmed that there is no significant difference between project managers and expert opinions. Research limitations: This research didn't consider the impact of project phase over the importance of each factor. As an example, the scope factor may become less important at the closing phase with respect to the planning phase. Practical implications: The results of this research could be used to develop an automated system to evaluate the project in quantitative way, rather than the usual qualitative methods. Originality: This research adopted a new approach to evaluate the relative importance of success factors using the Sigma Level (L) concept
