converted from market survey into customer requirements (WHATs). Product
characteristics are developed to achieve the customer needs in technical
descriptions (HOWS). House of quality is built by developing the relationship
between WHATS and HOWS. The result of house of quality is used in concept
generation. Pugh chart is used for concept selection. CAD models of the selected
concepts are presented.
In the current study, relative importance is allocated to the customer needs on a
scale of l to 5 (where 5 indicate the most important need and l indicates the least
important need). A finer scale such as l to 10 is suggested for relative
importance in the future research. Also in future research, Concept Classification
Tree and Concept Combination Table are recommended to be used in order to
produce better quality concepts for the forced exhaust system and the
multipurpose cup holder. Furthermore, the Concept Selection in the current study
is based on Concept Screening (Pough Chart) only. It is recommended to
consider the Concept Scoring stage too in the Concept Selection phase so that
high quality concepts may be selected.
