5.2 The following exhibit shows a partially completed House of Quality for a
proposed fitness center.
? Examine the relationships in the roof of the House of Quality.
Explain why they make sense (or if you think they do not,
explain why). How would this assessment help in the design
activity?
? Complete the matrix in the body of the House of Quality. That is,
examine each pair of customer and technical requirements and
determine if there is a very strong relationship, a strong
relationship, a weak relationship, or no relationship and fill in
the appropriate symbols in the matrix.
? Suppose that the most important customer requirements identified
through surveys and focus groups are !s programs I want, Family
activities available, Equipment available when desired, Easy to sign
up for programs,!nd ¡lue for your money. Staff available when
needed7as ranked low, while the remaining were ranked moderate in
importance. Based on this information, identify the most important
technical requirements that should be addressed in subsequent design
activities.

costly to replace. A highly skilled mechanic must disassemble the
transmission. If the part fails while it is in warranty, the
manufacturer pays the full cost of the repair to the garage or dealer
that did the repair. The manufacturer uses the Taguchi loss function
to set a specification for the part with . The dimensions for the part
are 1.0 0.10 centimeters.
? What is the economic value of one failed part?
? If the manufacturer of the part paid the full warranty cost on
1,862 failures last year worldwide, what is the total economic
cost of failure?
? If the manufacturer improved process and equipment
capability so the part specifications changed to 1.0 0.05
centimeters, what is the economic cost of one failure?
? Assuming failures were reduced by one half to 931 due to the
more precise specifications, what is the economic cost of
failure?
? How much warranty cost is saved according to Taguchi
estimates by improving specifications from .10 to .05?
