Matching of the Project Manager’s Approach and the Project Delivery System to Achieve Project Success in Yemeni Projects

The goal of this study is to seek answers to whether project managers’ approach is influenced by the project delivery system for achieving project success in Yemeni projects. A quantitative approach was adopted in this paper, and 375 project managers from two governorates of Yemen served as respondents. The idea is to assess the connection between the project managers’ approach (PMA) and the project delivery system (PDS). The results revealed that the project manager’s approach (participative and directive) and alignment with the project delivery systems (traditional or design and build) were directly linked with project success or failure. Moreover, the results revealed that the project managers adopting a participative approach have constructive effects, while the project managers adopting a directive approach harm project success. It is a chance for inexperienced project managers to receive advice on how to implement their management strategy and learn that, for Yemeni projects (YPs), every project delivery system requires a suitable approach to leadership.
