9. Work with one of your classmates as your customer; you are the supplier. Have your customer select a product and specify the customer attributes (CAs) that are
desirable. Then you specify the engineering characteristics (ECs) required to meet the customer’s needs. Complete the house-of-quality matrix by specifying the
relationships in the matrix. Ask your customer if the resulting ECs will meet his or her needs.
10. What are the essential benefits of using a QFD approach to product design? Also, identify any negative effects that might apply to the use of QFD.
11. A student would like to design a backpack for student books and supplies. The CAs are a (1) comfortable backpack that is (2) durable with (3) enough room
and (4) not too heavy to carry. Think of some ECs that can be used to measure these customer attributes. Then construct a QFD matrix showing the positive
and negative relationships that you expect to see in this case.
12. An entrepreneur is designing a sub sandwich shop that would be located on campus. Define the CAs that you would like to see for the service delivered at this location. Then specify some ECs that can be used for measurement of the service.
