隨著資訊科技與生產技術的大幅進步，企業經營環境產生巨大的變動。現代企業經營與過往相比較，除了必須面對全球市場競爭者外，顧客要求也日益提高，企業管理階層面對瞬息萬變的市場，如何利用企業內既有的資訊，迅速回應客戶、決定營運方向及作出對公司有利的管理決策，為管理階層須面對的管理課題。 個案公司為專業五金製造加工廠商，其產品具有產業環境快速變化、市場競爭、產品生命週期短、產品組合少量多樣等特性。公司管理階層面對此種產品特性，對於產品報價及產品成本分析資料有即時之需求，以快速回應客戶。個案公司由於資訊化程度不足，諸多管理資訊並未適當收集，因此無法有效提升管理決策之品質。 為解決個案公司所面臨之問題，需先針對其主要營運流程加以瞭解及分析，故本研究首先透過PWIO流程分析模式，辨認及描述個案公司之企業流程，且透過對作業流程的瞭解及實作分析，以其分析結果作為後續流程改善建議的基礎。由於個案公司並未完整建立產品成本及利潤資訊之蒐集制度，本研究以流程分析結果為基礎，透過對個案公司之資源耗用及成本發生情形進行分析，以瞭解個案公司資源耗用習性，並據以提出成本控制之建議。最後，本研究透過結合ABC制度的觀念，針對個案公司產品別成本資訊之收集與安排進行細部規劃，以供管理階層未來進行產品報價規劃及產品利潤分析之管理基礎，提升企業競爭力。 / The business environment has a great change with developing in information and production technology.
