Product design is typically a critical component in the early stages of a product development process. Product development has received much attention over the last decade. Classical multi criteria decision making methods are used in product design and development in the literature. Fuzzy sets approaches have a significant place among these works. Intuitionistic fuzzy, hesitant fuzzy, and type-2 fuzzy Quality Function Deployment (QFD) have been already developed in the literature. In this chapter, we employ the very recent extension of ordinary fuzzy sets, spherical fuzzy sets, in the house of quality development. For the comparison of competitive firms, spherical fuzzy TOPSIS (SF-TOPSIS) has been used. An illustrative application has also been given.
