效率是任何公司管理的一個主要追求目標。在現今瞬時萬變的企業環境中，一些企業組織渴望經由資訊系統來創造出競爭優勢。然而，在缺乏深入了解資訊系統的情況下，一些公司無法有效地經營企業。根據本研究觀察，此個案研究提出無論在企業內內或在企業間都能適用解決該問題之重要觀念，並且在使用與未使用資訊系統間比較其差異性。最後，本研究針對資訊系統運用問題的解決，提出三個命題：（1）資訊系統開發了公司內部之訂單作業方法，會使公司作業更有效率；（2）資訊系統結合電子資料交換及企業改造工程後，會使公司在經營上更有效率，並且，在市場占有上更具競爭性；（3）電子資料交換重新設計出公司跨組織功能的作業程序，更提升了公司營運效率。
