資訊系統(Information System, IS)的建置對於企業自身而言,早已是立足於競爭環境的基本訴求,審視資訊系統的建置策略:套裝軟體(Application Package)導入、自行開發與資訊委外(Outsourcing),各有其利弊,因此,如何有效的建置資訊系統,長久以來一直是備受矚目的焦點。 為了成功幫助企業順利建置符合自身運作流程所需之資訊系統,本研究以資訊系統開發模式的演進為依據,並且參考了以元件為基礎的軟體開發方法之執行概念後,提出了一套創新式資訊系統開發模式,稱為「旗艦式系統開發模式(Flagship Model)」,而為了落實其開發概念的實施,亦設計了一項系統分析開發工具(SADT),以Excel加上Visual Basic for Application(VBA)呈現出來。藉由開發概念與應用工具之間的相互配合,不僅能使繁雜的系統開發以功能設計的角度進行思量,更能改善資訊系統開發模式之缺失,確保系統開發的品質。
Information system construction has already been a basic demand for enterprise in current competitive environment. This research take the evolution of the information system development model as the basis and refer to the concept of component-based software development, then proposes an innovative model for developing information systems, named Flagship model. This model can improve the efficiency of system development. A system analysis and development tool (SADT) associated with Flagship model is also developed and presented in this research.
