採購部門之功能角色從企業中被動及支援者，逐步轉變成為今日具有影響企業策略之決策者。面對激烈的市場競爭，企業轉型時需以策略採購思維著手，將企業與採購策略相互配合方能創造客戶價值，增加企業競爭力。 本研究採取個案研究方法，經由蒐集個案公司及產業相關資料，並與管理階層訪談，瞭解個案公司面臨之管理議題。個案公司為大陸東莞之台資企業，產品為專業五金製品製造。為配合環境變遷面臨轉型，將生產重心由業電腦機殼轉移至大型遊戲機台組裝。遊戲機組裝市場特性為少量多樣與客製化，與原產品工業電腦型態相異，造成過往供應商物料短缺與新供應商開發困難。爾後與個案公司採購部門及相關部門多次深度訪談及焦點訪談，採用PWIO（Process Wide Information Organism）分析方法，詳實描繪企業採購及付款循環流程，將流程拆解成為請購、供應商管理、採購、驗收及應付款項處理作業向下延展至十一項作業功能並展開實作表，再將各作業流程細分為內、外向聯絡管道及接觸點並具體詳實描述。 透過PWIO描述及分析採購作業流程，找出造成個案公司管理議題之採購流程缺失，包含隨機篩選新供應商、新承認供應商直接成為合格供應商、供應商管理策略與企業策略未結合、供應商評鑑缺乏客觀衡量標準、及供應商評鑑作業未與執行面配合。經由產業專家訪談、產業相關資訊之蒐集，及層級分析法(AHP)之應用，針對五項流程缺失給予改善建議方案，包含建立供應商初步媒合流程、配合企業策略設計新供應商評量表、建立新舊供應商分流管理制度、以企業策略著眼設計供應商評鑑表、及加強變革成效，促進新制度落實與執行五面向。以上建議方案可加強企業及採購策略之配合度，透過新舊供應商評鑑與管理篩選適當合作之供應商，將採購流程制度化，進而改善目前採購流程之問題。 / Strategic procurement is crucial to strengthen a company’s core competence in the competition among enterprises.
