Impact of elements of complexity on project success

Research on the elements of complexity as some of the key factors influencing project success has become important among researchers and practitioners in the construction industry. Considering the most common contracting methods today, and because most resources of a project rely on contractors, the control of many indicators that affect project success is transferred to the contractor. This paper presents an analysis of the impact of elements of complexity on project success during the construction phase. Through a survey with project managers, we analyzed the impact of elements of complexity on the success of a project through five phases of construction. The results of the analysis are presented through different graphs showing changes in the intensity of the impact of complexity on project success. The research showed that elements of complexity have the most significant impact on the success of a project in the execution phase. The results can assist contractors to pay more attention in certain phases of the projects to specific elements of complexity and thus impact the success of the project.
