| 摘要: | 根據專案管理機構研究報告指出：高達70%以上軟體專案皆失敗，50%以上軟體專案未能達到預期目標，美國電子電機工程師學會及主計處統計調查指出：需求的不確定造成認知差異、需求變更頻繁往往是導致專案失敗的兩大主因。然而，在軟體開發中初始階段的需求擷取，解決認知差異尤為重要。為解決此問題，在未來研究方方法論中，未來輪由於易用性、幫助周延思考、更具組織性，故能應用於系統分析領域，因此本研究導入未來輪作為需求擷取流程的輔助工具，並明確化需求流程，導出物件導向塑模之使用者案例模型，並評估流程可用性，提供執行建議與指示。
研究採用個案研究法，以探索、發現、和歸納的邏輯為導向，針對個案進行詳細的研究，結合文獻內容分析與專家訪談進行探討，針對訪談結果提出研究命題、流程驗證及調整。
本研究具體貢獻包含建立導入未來輪之需求擷取流程，描述各階段該如何執行，並將未來輪結合物件導向塑模。透過專家訪談資料，驗證流程可用性並提出研究命題，分析出流程三種不同狀況：輔助需求擷取、塑模調整、制定專案目標的可能性，並提出流程執行建議。
According to Project Management Institute research: over 70% or more software projects fail
50% of software projects cannot meet customers’ expectations. The American Institute of Electrical and Electronics Engineers also found that cognitive differences caused by uncertain requirement and frequently changing requirement were the two main reasons leading to project’s failure. However, in the initial stages of the software development, requirements elicitation is particularly important to solve cognitive differences. To solve this problem, future wheel, a method of future research methodology, containing the easy accessibility, sustainability, and organized, could be applied in system analysis domain. Therefore, this study by introducing the future wheel as a supplementary tool to create a requirement elicitation process, and through the process to export object-oriented model-use case model. Finally, it evaluates process’ availability and practice's instructions.
Individual case study method is adopted and is oriented by the logic of exploring, discovering and inducing. The prepositions, process’ verifications, and adjustment by concluding the references and expert’s suggestions in interview are proposed by this paper.
The contributions of the research include creating the process of using future wheel in requirement elicitation, providing instructions of the process, and combining future wheel with object-oriented model. Besides, this study possibility of future wheel in three different situations: assisting requirement elicitation, model adjustment, project goals setting. |
