Experiment with the QFD Process through an example: Designing a Refrigerator Complaints about the old refrigerator include: ■ the refrigerator is unreliable and noisy, ■ the shelves can't hold large containers and ■ cannot be rearranged,and ■ the refrigerator is difficult to clean. Marketing has expressed an interest in the new refrigerator having a water and ice dispenser. Field service has indicated they have experienced failures ■ when refrigerators fall off the delivery truck and ■ have complaints that they are difficult to install
