To solve the challenge of deciding which modules should be chosen when developing new products, a new methodology has been proposes. This module selection method combines Kano model into a QFD framework to get the final importance of modules. The QFD approach is first applied to get initial importance ratio. Then, the application of the Kano model adjusts the importance ratio with a consideration of overall satisfaction. Thereafter, the final relative importance can be determined by using QFD function. A process model is given to apply the method successfully and unambiguously. Finally, the feasibility and efficiency of this method is demonstrated by a case study.
