摘要

隨著資訊科技的進步，應用資訊系統創新企業營運模式已蔚為潮流，不管以何種開發模式建置資訊系統，過程中皆須進行需求分析流程；但需求分析人員對於商業流程及領域技術的專業知識，往往力有未逮，導致需求分析結果與實際顧客所需產生落差，最後無法達到預期的功能要求。
依據The Standish Group國際研究機構統計[7]，目前大多數系統建置失敗的主因，並非導因於軟體發展技術，而是需求分析不當所致。
因此，本研究擬依循既有資訊系統開發模式，提出一套創新「視覺化輔助需求分析」模式，並建構出一套視覺化輔助分析工具－Page Producer，藉此讓需求分析人員在進行需求擷取的過程中，亦能即時依使用者的訴求架構出系統雛型，讓顧客以視覺化的方式得知系統雛型的架構，以確保雙方對需求規格認知的吻合度。
最後藉由案例的實作與模擬，分析傳統模式與本研究所提出之視覺化輔助需求分析模式於系統開發流程上效益的比較，進而歸納與整理出本研究的貢獻與價值所在。

With the advance in the information technology, it has been popular that the model of the business operation adopts the innovative applied information system.
No matter which developed model set by the information system, the procedures of the requirement analysis have been carried out in the process. But the requirement analysis people can’t understand enough specific knowledge about the business procedure and the technological field. It causes a drop between the results of requirement analysis and the customers’ need in the reality so that it can’t reach the expectation of the demand of the function at last.
According to the statistics by The Standish Group international research organization, the main reason that the most of the systems has failed the setting is that requirement analysis is improper instead of the developed technology of the software.
Therefore, the research follows the developed model of information system to submit a set of an innovative model “Visual aided Requirement Analysis” and a set of instrument- Page Producer. In this way, the requirement analysis people can construct a system model satisfying with the demand of users in time in the midst of the procedure of picking the requirement. Let customers know the configuration of the system model by visual way to ensure both sides of people cognizing the standard of requirement.
At last by the case of practical operation and simulation, institute a comparison of the benefit between traditional model and the requirement analysis model raised by the research while develop the system and further conclude and sort out what’s the contribution and value of the research is.
