Abstract:	根據2013年Standish Group CHAOS 報告，指出61%的專案有品質不良、超出預算或失敗等問題，此狀況在大型專案影響更鉅；故探討大型專案建置階段所遭遇的問題、分析主要因素、提出改善建議是當前值得研究的內容。本研究採用個案分析法，以政府某大型資訊系統委外服務案為研究對象，探討該個案於2010年至2012年共2年8個月建置階段遭遇的問題，將問題分為5個構面類型、25個問題因素、3個影響程度等級及7個軟體生命週期階段等進行相關研究。研究分析得知80%的問題來自「人力資源」、「系統需求」、「流程管理」及「文件品質」構面，且最嚴重的前三名問題因素依序為「人力資源不足，沒有充分的時間將工作做好」、「成員欠缺足夠的技術與經驗」及「成員的流動性高，經常在遞補人員」，此前三名問題因素皆屬人力資源構面佔48.55%。本研究將前述80%的問題，再依問題屬性歸類為五項關鍵問題，分別為「專案規劃階段估算誤差過大」、「未考量各方人力溝通所需的人力與時間」、「領域知識了解不夠」、「專案管理及軟體發展素質不夠」及「軟體發展重工率高」，並針對發現的關鍵問題進行原因探討，提出建議解決方案，供後續其它大型軟體專案參考。 According to the 2013 Standish Group CHAOS report, 61% of projects face problems such as inferior quality, over-budget or failure; this is even more so in large-scale projects. Consequently, the study examines the problems encountered by large-scale projects during implementation, where main factors are analyzed to propose suggestions for improvements. The study adopts the case analysis method to study a certain government large-scale outsourced system project, where the problems encountered during the implementation phase between 2010 and 2012 (duration of 2 years and 8 months) are examined. The problems are divided into 5 dimensions, 25 factors, 3 impact levels and 7 software development life cycles for research purposes. According to analysis results, 80% of the problems originate from personnel resources, system requirements, process management and documentation quality dimensions. The top three problem factors are “lack of resources and time”, “insufficient skills or experience” and “frequent turnover within the project team” in that order. The three major problems constitute 48.55% of the personnel resources dimension. The research categorizes 80% of the aforementioned problems into five key problems based on their respective attributes. They are: “error margin too large during the project planning phase”, “failure to consider the manpower and time needed for communicating with all parties involved”, “lack of understanding about the industry”, “inadequate project management and software development training” and “software development rework rate too high”. The study further examines the reasons behind these key problems and proposes solutions in order to provide reference for other large-scale software development projects in the future.
