手機產業從品牌廠到代工廠的競爭都非常激烈，其產業特性具高複雜性與市場變動快速，手機軟體開發不斷的尋求更有效益的管理方法，以達到更高的開發品質，更短的開發時程，以及更快速的市場應變能力，讓客戶以及公司達到利益最大化。相關研究探討中會說明軟體開發方法論中的瀑布式模型以及敏捷式模型，進而說明到產品開發的關卡式流程，再來會介紹到關卡式流程與敏捷式的混合式模型。本研究挑選較為合適的專案進行個案分析，分析中會先說明手機產業特性以及軟體流程，其流程為傳統的瀑布式模型，再來會說明到這次的個案，個案中使用的是敏捷式開發流程，但導入時會和文獻中的有所不同，因為敏捷式模型是無法套用到所有產業和部門的，所以本研究中也會說明到個案是如何套用敏捷式模型。分析成果的部份，本研究會以定量和定性兩個方式進行，首先，針對初級、次級資料做分析，並在開發時間、人力投入、專案管控等數據資料做討論，以確認敏捷式方式是否可以帶來實際的好處；再來會針對個案同仁進行訪談，以確認在個案中的敏捷方式，是否如同數據中的表現，在數據資料以外方面，對組織是否帶來正面或負面的影響；最後，當發現問題因子時，提列出來進行田口分析，並找出流程的最佳組合。雖然敏捷式開發是以軟體開發做基礎的專案管理方法，但面對嵌入式系統類的軟體卻發現了諸多的限制，混合式模型勢必成為類似方案的解決方法，而如何將傳統流程法和敏捷式方式做混合，將其運用找到一個更合適的平衡點，便是每個執行人員所面臨到的難題，所以個案中的經驗便有著研究的價值。;The competition of the mobile phone industry from brand factories to foundries is very fierce. Its industrial characteristics are highly complex and the market changes rapidly. The purpose of this research is to find more effective mobile phone software development meth-ods to achieve higher development quality, shorter development timeline, and faster market contingency, to maximize the benefits of customers and companies. The case analysis de-scribes the characteristics of the mobile phone industry and the software process. The process is a traditional waterfall model, then explain to this case. The case uses an agile development process. The adopted model is different from literature, due to the agile model cannot be ap-plied to all industries and departments, so this case study shows how the case is applied to the agile model. This research is conducted in two ways. First, analyze the primary and secondary data, and discuss the development time, manpower input, and project management and control to confirm whether the agile method can bring practical benefits. Interviews with individual colleagues to confirm whether the agile approach in the case is like the performance in the data and whether it has a positive or negative impact on the organization in addition to the data. When problem factors are found, Taguchi method is used to find the best combination of processes. Although agile development is a project management method based on software develop¬ment, in the face of embedded system software, it has found many limitations. The hybrid model is bound to be a solution, and it is worth to study on how to use traditional process methods mixing with agile to find a more appropriate balance point is the problem faced by each executive.
