Chapter 4 Understand the problem and the development of engineering specification 1
4.1 Introduction 介紹朋友的條件 條件: 要帥 要有車
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
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?
Collection method for customers’ requirement Three ways to collect: • Observation, • Surveys, • Focus group
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
3.3.2 Collection method for customers’ requirement Three way to collect: • Observation, • Surveys, • Focus group
4.5 Step 3: Determine relative importance of the requirements: Who Versus What Scale 1 to 10
4.6 Step 4: Identify and evaluate the competition: How satisfied is the customer now
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.
4.7 Step 5: Generate engineering specifications: How will the customers’ requirements be meet?
4.8 Step 6: Relate customers’ requirements to engineering specifications: how to measure what?
4.9 Step 7: Set engineering targets: How much is good enough?
4.10 Step 8: identify relationships between engineering requirements: How are the hows dependent on each other?
