  1. Chapter 4 Understand the problem and the development of engineering specification 1

  2. 4.1 Introduction 介紹朋友的條件 條件: 要帥 要有車

  3. History of Optical disk • 1980年荷蘭飛利浦公司與日本新力公司共同發表全球第一片CD (Compact Disc CD光碟機) • CD-ROM光碟機---儲存量大，不可一世      • CD-I互動光碟機---應用軟體少，提前腰斬     • PHOTO CD光碟機---市場接受度，寥寥可數       • VCD光碟機 --- 儲存應用廣，曾風光一度    • DVD影音光碟機---多功能技術，一枝獨秀   • 可錄製一次光碟機標準(CD-R) • 可重複讀寫型光碟機標準(CD-RW)。 • DVD-ROM---儲存量更大，前景無限 • 答案:象棋

  4. 4-2 QFD (Quality Function Deployment)

  5. Steps of QFD Step 1: Identify the customs: Who are they Step 2: Determine the customer requirement Step 3: Determine relative importance of the requirements: Who Versus What Step 4: Identify and evaluate the competition: How satisfied is the customer now Step 6: Relate customers’ requirements to engineering specifications: how to measure what? Step 7 Set engineering targets: How much is good enough? Step 8: Identify relationships between engineering requirements: How are the hows dependent on each other?

  6. Collection method for customers’ requirement Three ways to collect: • Observation, • Surveys, • Focus group

  7. Example questions including in the survey are:

  8. The type of Customers’ requirements

  9. 4.3 Step 1: Identify the customs: Who are they

  10. 4.4 Step 2: Determine the customer requirement • Customer requirement • Production customer want • -Easy to manufacturing • 3. Marketing/sales customer wan • -Easy to package, transport, is attractive, is suitable to display

  11. 4.4.1 the Kano model of customer satisfaction

  12. 3.3.2 Collection method for customers’ requirement Three way to collect: • Observation, • Surveys, • Focus group

  13. Step to help the design team develop useful data

  14. Example questions including in the survey are:

  15. 4.4.3 The type of Customers’ requirements

  16. 4.5 Step 3: Determine relative importance of the requirements: Who Versus What Scale 1 to 10

  17. 4.6 Step 4: Identify and evaluate the competition: How satisfied is the customer now

  18. Rate the design on a scale of 1 to 5 • The product does not meet the requirement at all. • The product meets the requirement slightly. • The product meets the requirement somewhat. • The product meets the requirement mostly. • The product meets the requirement completely.

  19. 4.7 Step 5: Generate engineering specifications: How will the customers’ requirements be meet?

  20. 4.8 Step 6: Relate customers’ requirements to engineering specifications: how to measure what?

  21. 4.9 Step 7: Set engineering targets: How much is good enough?

  22. 4.10 Step 8: identify relationships between engineering requirements: How are the hows dependent on each other?
