專案採購五大要素包括供應商、時間、價格、數量以及品質。完整定義營建工程專案採購管理作業範圍，直接影響各階段品質的良窳。專案採購管理（PPM）作業對於工程生命週期各階段有著不可分割的關聯性。專案前置作業的採購計畫、時程與成本的管控、廠商評選等作業，皆需考量組織策略與執行環境需求。本研究運用專案定義評級指數（PDRI）評估模式做為專案前期整合性的評估。運用Mindjet Mind manager軟體做為採購作業範疇研討整合工具。PPM-PDRI評估模式共分為3個部分、17個目標種類和80個要素。此評估模式經本研究驗證，在專案作業範圍定義成果符合＜ 200分的情況之下，於成本管理的績效上低於預算的3%，在專案進度管理的執行績效超前預定進度的4%，而於專案設計變更的管制績效，控制在預算的5%範圍內。研究成果驗證以PPM-PDRI評估模式進行專案採購管理，對於營建專案的成本、進度、設計變更、施工品質與材料的品質管控，有實質上的助益。

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.
