  1. Manufacturing Quality Management 生產品質管理

  2. Outline • Quality Definition • House of Quality (HOQ) Application • Statistical Process Control (SPC)統計流程控制 • The Cost of Quality品質成本 • Quality Experts and Key Concepts • TQM • Quality circle • Six Sigma • ISO 9000 IT/S in Manufacturing

  3. Definition of Quality • Conformance to requirements與需求相符: meeting written specifications IT/S in Manufacturing

  4. A Simple HOQ（House of Quality) Matrix A matrix defines the relationship between the requirements of customer and product characteristic IT/S in Manufacturing

  5. An example of HOQ Matrix product characteristic Customer’s requirements IT/S in Manufacturing

  6. A Detailed HOQ 產品特性相互關係 重要性 客戶對商品之認知及比較 技術評估及目標值 IT/S in Manufacturing

  7. An example of Detailed HOQ Matrix IT/S in Manufacturing

  8. Linked Quality Function Deployment (QFD)品質功能部署 Matrices 品質屋　　　 　　　　　組件選用　 　　　　　　　　　　　流程規畫　 　　　　　　　　　　　　　　　　　生產需求 IT/S in Manufacturing

  9. Quality Function Deployment (QFD)品質功能部署之優點 • 常用之工具，製造及服務業皆然 • 有系統的暸解客戶需求，並轉換成技術需求。 • 便於提早確定產品特性，降低修改設計的風險，減少產品之前置時間。 • 利於單位間之協調與合作 • 可借以開發出新產品 IT/S in Manufacturing

  10. 統計流程控制Statistical Process Control (SPC)-Out of Control IT/S in Manufacturing

  11. 統計流程控制Statistical Process Control (SPC)-in Control • 都在區間內，且接近平均值 • 上下比例大至相同 • 無不常之型態 IT/S in Manufacturing

  12. The Cost of Quality品質成本 • Cost of conformance (COC): delivering products that meet requirements and fitness for use達到完成品符合需求，並適合使用所耗費的成本 • Cost of nonconformance (CONC): taking responsibility for failures or not meeting quality expectations負擔失敗或未能與品質期望相符責任的成本 IT/S in Manufacturing

  13. Cost of Quality IT/S in Manufacturing

  14. Five Cost Categories Related to Quality • Prevention cost: the cost of planning and executing a project so it is error-free or within an acceptable error range 「預防成本」 • Appraisal cost: the cost of evaluating processes and their outputs to ensure quality 「鑑定成本」 • Internal failure cost: cost incurred to correct an identified defect before the customer receives the product 「內部錯誤成本」 • External failure cost: cost that relates to all errors not detected and corrected before delivery to the customer 「外部錯誤成本」 • Measurement and test equipment costs: capital cost of equipment used to perform prevention and appraisal activities 「衡量與測試設備成本」 IT/S in Manufacturing

  15. 品質成本（傳統vs.現在觀點比較） IT/S in Manufacturing

  16. Modern Quality Management • requires customer satisfaction客戶滿意 • prefers prevention to inspection預防勝於檢驗 • recognizes management responsibility for quality確認品質管理的責任 IT/S in Manufacturing

  17. Quality Experts • Deming was famous for his work in rebuilding Japan and his 14 points戴明十四點管理原則 • Juran wrote the Quality Control Handbook and 10 steps to quality improvement裘蘭「品質改善」 • Crosby wrote Quality is Free and suggested that organizations strive for zero defects • Ishikawa developed the concept of quality circles and pioneered the use of Fishbone diagrams石川馨「品管圈」及「魚骨圖」 • Taguchi developed methods for optimizing the process of engineering experimentation田口玄一「品質工程」 • Feigenbaum developed the concept of total quality control魏根堡「全面品質控制」 IT/S in Manufacturing

  18. Fishbone or Ishikawa Diagram IT/S in Manufacturing

  19. Quality Circle品管圈 組織 訓練 問題辨認 問題分析 解決 報告 IT/S in Manufacturing

  20. Normal Distribution and Standard Deviation常態分配與標準差 IT/S in Manufacturing

  21. Six Sigma and Defective Units IT/S in Manufacturing

  22. DMAIC • Define: Define the problem/opportunity, process, and customer requirements • Measure: Define measures, collect, compile, and display data • Analyze: Scrutinize process details to find improvement opportunities • Improve: Generate solutions and ideas for improving the problem • Control: Track and verify the stability of the improvements and the predictability of the solution IT/S in Manufacturing

  23. Total Quality Management (TQM) • Customers Define Quality • Quality Leadership and Responsibility • Strategic planning • Continuous Improvement • Cooperation • Statistical methods • Education IT/S in Manufacturing

  24. Quality Certification (品管認証）ISO9000 IT/S in Manufacturing

  25. 隨堂作業 • 請以組為單位，選擇一開發生產之商品（可以和作業一之產品相同），依課堂所授之 HOQ（House of Quality) Matrix（P4,5），繪製成表 : • 定義客戶對此商品之需求 • 再依此需求決定產品之特性 • 最後衡量各需求與各特性之關係，並統計各產品特性之重要性。 IT/S in Manufacturing
