To enhance quality control by using PDRI to define scope of project procurement

Project procurement management (PPM) contains 5 major elements; suppliers, time, price, quantity and quality. These elements directly affect the quality of procurement in different phases. PPM is indivisibly associated with different stages of the engineering life cycle. In preliminary planning and scheduling of project, and the control of cost and screening of suppliers, organizational strategy and the needs of the operational environment should be considered. In this study, the Project Definition Rating Index (PDRI) is adopted for the evaluation of the preliminary integration of a project. Mindjet Mind manager software is adopted as the tool for integration of the study within the defined scope. The PPM-PDRI model consists of 3 Sections, 17 Categories, and 80 Elements. This model is subject to validation in this study, when project scope definition is < 200 points, the actual cost is 3% below the budget, the actual progress is 4% ahead of schedule and the change order is controlled within 5% of the budget. Thus, it has been proved from the study result that, in terms of cost, schedule, change orders, construction quality and material quality, the PPM-PDRI model perfectly defines the scope of project procurement and effectively improves the performance of project quality management.
