4. 4 4-2 QFD (Quality Function Deployment)

6. 6

7. 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. 8 Collection method for customers’ requirement Three ways to collect: Observation, Surveys, Focus group

9. 9 Example questions including in the survey are:

10. 10

11. 11 The type of Customers’ requirements

12. 4.3 Step 1: Identify the customs: Who are they

13. 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

15. 4.4.1 the Kano model of customer satisfaction

16. 3.3.2 Collection method for customers’ requirement Three way to collect: Observation, Surveys, Focus group

17. Step to help the design team develop useful data

20. Example questions including in the survey are:

22. 4.4.3 The type of Customers’ requirements

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

25. 4.6 Step 4: Identify and evaluate the competition: How satisfied is the customer now

26. 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.

27. 4.7 Step 5: Generate engineering specifications: How will the customers’ requirements be meet?

28. 4.8 Step 6: Relate customers’ requirements to engineering specifications: how to measure what?

29. 4.9 Step 7: Set engineering targets: How much is good enough?

30. 4.10 Step 8: identify relationships between engineering requirements: How are the hows dependent on each other?
