我國銀行業於1991年開放新民營銀行設立，使得整體銀行的服務水準得以提升，新金融商品的開發更加快速，但利率自由化，以及各銀行採取價格競爭策略爭取客戶之作法，使得存放款利差日益縮小，各項經營風險隨之提高。金融機構惡性競爭不僅導致銀行授信品質日益惡化，同時也壓縮了銀行的獲利能力。近年來台灣經濟的不景氣與金融環境快速的變化，金融業的競爭優勢將取決於對市場、顧客及競爭同業能否做出最佳及最具差異化之決策。然而金融業收入之穩定來源，取決於企業流程作業之有效性，企業需要檢視其作業流程以消除無效率及無附加價值的作業，以降低成本、提升作業效率及效能。本研究應用企業流程資訊有機體分析架構(Tsaih and Lin 2006)，透過重現、系統化分析個案公司之房貸業務授信循環流程，並於評估流程實作後，提出相對應之作業流程及管理資訊之改善建議與管理議題，以提供個案公司做為未來管理房貸授信風險決策之參考。 / The deregulation of the Taiwan Banking industry started in 1991 has enhanced the quality of the financial service as well as speeded up the development of new financial products. The deregulation not only leads to the liberation of interest rate but also opens up the price competition between banks in order to attract customer and keep continuous sales growth. Such effect has depressed the spread of interest rate and instigated various operating risks. The cutthroat competition between banks results in deterioration of credit granting quality and reducetion in profitability. Due to the economic recession in Taiwan and the fast changing of financial environment in the recent years, the competitive advantages of the financial industry are determined by whether a bank is capable of making the best and differentiated reactions to market, customers and its competitors. The stability of the income generation to the financial industry depends mostly on the effectiveness and efficiency of the business processes. It is essential for an organization to oversee its business process to reduce less efficient, non-value-adding activities and costs. This study, based on an application to the Process-Wide Information Organism approach (Tsaih and Lin. 2006), investigates the mortgage loan business process of the subject company. By reconstructing and analyzing the practice of granting a mortgage loan, this study is able to provide corresponding suggestions with respect to process improvements and related managerial implications to the subject company.
