1 1 Chapter 4 Understand the problem and the development of engineering specification 4.1 Introduction : History of Optical disk 1980 CD (Compact Disc CD ) CD-ROM --- CD-I --- PHOTO CD --- VCD --- DVD --- (CD-R) (CD-RW) DVD-ROM--- : 4 4-2 QFD (Quality Function Deployment) 6 7 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? 8 Collection method for customers requirement Three ways to collect: Observation, Surveys, Focus group 9 Example questions including in the survey are: 10 11 The type of Customers requirements 4.3 Step 1: Identify the customs: Who are they 4.4 Step 2: Determine the customer requirement 1.Customer requirement 2.Production customer want -Easy to manufacturing 3. Marketing/sales customer wan -Easy to package, transport, is attractive, is suitable to display 4.4.1 the Kano model of customer satisfaction 3.3.2 Collection method for customers requirement Three way to collect: Observation, Surveys, Focus group Step to help the design team develop useful data Example questions including in the survey are: 4.4.3 The type of Customers requirements Scale 1 to Step 3: Determine relative importance of the requirements: Who Versus What 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 1.The product does not meet the requirement at all. 2.The product meets the requirement slightly. 3.The product meets the requirement somewhat. 4.The product meets the requirement mostly. 5.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? 31
