Abstract:	面對顧客快速變化的需求及全球化的腳步，如何於新產品開發中採用較有效率的做法，提升設計品質，及在最短的時間內，設計出符合市場需求的產品，是企業成敗的關鍵要素，也是企業成功的的先決條件。因此在設計階段把設計人員與製造、製程、品保相關工程人員聚集一起，共同研討最佳化之設計是相當重要的。本研究以Q公司伺服器產品為例，應用失效模式與效應分析(Failure Mode and Effects Analysis，簡稱FMEA )之方法針對產品的主要零組件，探討產品性能表現及可靠度提昇等兩大訴求，透過專案團隊，對產品功能作系統性分析，找出可能發生的失效現象及可能原因、評估其嚴重度( Severity )、發生度( Occurrence )及難檢度( Detection )，再經過計算求得風險優先指數(RPN)，並依照RPN值的高低決定失效問題解決的優先順序及解決方案，並於解決方案實施之後，重新計算RPN值。在完成FMEA資料分析評估後，可協助工程師在工程設計早期發現潛在缺陷及評估其影響程度，及早謀求解決之道，以避免失效之發生，或降低其發生時產生之影響。本研究所獲致成果，不但增進公司人員對產品和製程控制能力的知識，改善產品開發設計之品質，同時大幅降低後期設計變更的次數，縮短產品研發週期，而分析之結果亦可在企業內部建立資料庫，以提供後續設計者的參考，進而達到提昇產品設計品質及可靠度。 Facing end customer rapidly demand change and globalization influence, the key factor to corporate success is to deliver new product which meets market needs, effective design and high quality standard in shortest development cycle. Therefore, it is quite important to consolidate corporate resources and gather all function teams to study and finalize design concept during early development stage. The research is taking Q company’s server as example, apply FMEA on server products’ key components, two major characteristics which are product performance and reliability enhancement as measure standard, through product development team to systematically analyze failures and root cause it. Evaluate its severity, occurrence and detection, then calculate RPN, sort out priority list and solutions according to RPN value, re-calculate RPN and solution applied to it. A successful FMEA can help engineer discover potential risk and its impact in early design stage and look for solution to avoid impact once failure occurs. The research could enable engineers gain knowledge of product and process control ability, improve quality of product design, in the meantime, it will reduce the recurrence of design changes thereby to reduce design cycle and cost. Corporate could also build database to internal tracking analysis result for future product development team as reference thus to improve product design quality and reliability.
