EVALUATING SUCCESS FACTORS IN EPC PROJECTS: CASE STUDY; MAPNA POWER PLANT PROJECTS

In project-based organizations, project success is a key goal and challenge for managers, as they plan to com¬plete the projects within the time, cost, and quality constraints according to the customers. Many factors contribute to success, as the subject has been studied extensively in the literature for internal projects. Most notably, Pinto and Slovin have empirically developed a 10 factor project success model for a sample of projects within various organizations. This research re-examines the subject for EPC projects, where an entire cycle of Engineering-Procurement- Con¬struction has been outsourced to a prime contractor, who may, in turn, sub-contract parts of the project to other firms. We have used data from MAPNA Group power plant projects, a major EPC contractor in Iran with a success track record, for empirical analysis. For a limited model, with 5 selected success factors and using a questionnaire, we were able to verify the factors for EPC cases. The final analysis shows that Project Mission and Definition, Top Management Support, Plan¬ning and Scheduling, Human Resources, and Technical Tasks are all important factors believed to contribute to the EPC project success; Planning having the least relative effect.
