本研究認為，資訊技術與管理能夠協助企業面對競爭環境與經營的挑戰。企業若能應用服務導向架構 (Service-Oriented Architecture, SOA) 整合企業採購流程、並推廣到企業經營流程，將可協助統整企業的人員、資訊、流程、及應用系統，同時迅速、有效的提供整體資訊管理服務，及提升企業資訊管理人員的技能，成為企業經營顧問。
因此，本研究應用服務導向架構之技術平台，透過對個案之研究探討，對於其企業採購流程提出軟體架構之發展與規劃。研究結果顯示，個案在其採購流程整合之後，透過關鍵績效指標 (Key Performance Indicators, KPI) 之檢核，在請購平均週期時間、採購平均週期時間、簽核文件遺失率、採購疑點諮詢之電話量、自動化之建立等五方面，確實達到縮短採購循環之時間、降低採購時額外之成本、能專注於採購專業、保存採購程序之文件、提供採購循環之管理報表、企業採購流程之快速轉移等實質效益。因此，綜而言之，應用服務導向架構於企業採購流程之整合，企業整體效益包括：降低成本、提供流程透明度、應用服務導向架構技術平台建立更多企業流程等方面，獲得實質效益。
本研究同時發現，企業採購流程整合後，除了前述企業所獲得的實質效益外，也對於企業資訊技術產生影響，包括：資訊系統分層級規劃、整合企業服務之應用系統服務寶庫、及引導至更寬闊的應用等方面。另外，本研究亦發現，整合及規劃企業採購流程之初，應訂定企業策略及資訊策略兩方面的行動方案，以作為企業流程整合的指導方針。
對於未來的相關研究，本研究提出：整合如何遍及其他企業流程、資訊安全風險、整合對象產生之瓶頸、及企業政策與規範之困難等方面之建議。期待能協助企業發展更完整、適用、及安全之企業流程管理之外，亦能提升企業資訊管理與資訊人員成為企業經營顧問，並應用服務導向架構協助企業之永續經營。

Successful enterprise procurement processes require that people, information, process and application be merged into a cohesive and optimal software architecture, which is described as a service-oriented architecture (SOA). The information management staff applying SOA to their procurement processes will advance their ability and promote themselves as consultants on the enterprise processes.
This research aims to explore the benefits of integrating the enterprise procurement processes based on a SOA platform. Through a case study, the benefits found and proved include: decreasing lead time by replacing existing manual processes with the web-enable and standardized procurement processes, reducing the extra cost of procurement, helping buyers focus on the professional skills, preserving the procurement documents, providing the management reports, allowing efficient integration of requirements on demand, and assisting to transfer such an experience more rapidly to other applications.
It is also found that the integration of enterprise procurement processes based on SOA brings about influences on information management itself. For example, it makes different specific layers of IT services in order to link separate and distinct functions, integrates heterogeneous applications and platforms into a business service repository, and pilots some more potential applications to other enterprise processes. In addition, this research also reveals the importance and necessity of making action items and information technology (IT) policies for the enterprise before integrating. The enterprise had better make action items and IT policies as a main guide to the integration and development of enterprise processes.
