自從工業革命後，製造業就一直在追逐交貨的快速與及時性。近年來，隨著資訊及科技的進步及發展，市場的需求也相對應產生快速變化，而企業也面臨外在市場環境的「不確定性」、「複雜性」和「競爭性」等特性。
但也因為市場需求的快速變化，加上企業內部管理所作業上的問題，造成企業在評估及預測儲存庫存的「數量－多少?」及「時間點－何時?」產生困難；庫存太少，可能造成無法準時交貨而產生顧客不滿意甚而產生客源流失，但庫存太高則可能造成存貨成本過高，而亦因市場快速變化，甚而可能形成呆滯庫存，造成企業成本增加。
現代化的企業經營，不能再像幾十年前一般，僅靠著人工作業的模式營運，因為放在人腦的資訊若是不透過資訊科技的運用，是無法讓企業的分工如預期般被執行和完成，而傳統的人工作業或是不即時的作業模式，正是企業無法有效管理市場的「不確定性」、「複雜性」和「競爭性」的主因。
個案公司因其行業的特性，在面對市場需求快速變化及人工作業模式營運的不足下，而面臨到『高庫存量』、『高材料短缺率』及『低客戶滿意度』此三大問題，如何兼顧備料時機，同時又能充分掌握客戶出貨時間，實為零件組裝廠的一大挑戰；為了解決這些問題，該公司階段性的導入MRPII、ERP及APS等管理資訊系統，來幫助企業有效營運管理。
本研究採用探索性的個案研究，籍由探討個案公司如何導入相關的管理資訊系統來解決『高庫存量』、『高材料短缺率』及『低客戶滿意度』等問題，以使公司獲得更高的營運績效，並與3C理論相印證。

Since the 19th century Industrial Resolution, what manufacturers have been pursuing is fast and on-time delivery; however, at the age of information technology, market demand changes relatively rapidly, all enterprises have to confront the external market environment, such as uncertainty, complexity and competition.
Due to the rapid change of market demand, it is a big challenge for companies to do precise inventory planning. Deficient stock volume may cause late delivery and low customer satisfaction or even customer loss, while over inventory may result in high stock cost, obsolete dissipation and in heavy management cost.
Both human knowledge and information technology are required for modern business management. All data in computer system can be applied completely for every division of the enterprise when it is compared to in human brain. The traditional human operation and “non-just-in-time” operation mode is concerned as the major cause of a firm’s difficulty to fight with the uncertainty, complexity and competition from the market.
Due to the fierce competitive external market and the inefficient internal human operation, the case company is forced to face the three problems: over stock inventory, serious shorted key component and low customer satisfaction. It is a big challenge for the case company to control their materials to meet customer’s request. The implementation of Management Information System such as MRPII, ERP and APS in different stage is considered as a good solution to this company.
The research method is exploratory case study research. By the implementation of management information system, the case company improved the conditions of “over stock inventory”, “serious shorted key component” and “low customer satisfaction” as well as reached a better operation performance. It is a good example for 3C theory.
