Integration of Preference Analysis Methods into QFD for Elderly People

Abstract

In the work of Pullman, Moore, and Wardell, they compared the QFD and conjoint analysis methods on the example of a new all purpose climbing harness for the beginning/ intermediate ability climbers. They view the two methods QFD and conjoint analysis “as complementary approaches that should be conducted simultaneously,” in which each method’s result supports the other. They concluded that QFD and conjoint analysis provide two “different lenses” that combine the product developers and the marketers in producing new or improved product (Pullman et al. 2002, p. 354).
