A Methodological Comparison of Three Approaches for Product Development using Fuzzy TOPSIS

The elevated erudition of New Product Development (NPD) requires involvement of a cross-functional team viz, innovation, design, marketing, sales, pricing, business model creation, product strategy, finance, user experience design, and technical architecture. In such condition it’s hard to fix the product design process. Several methodologies are proposed in literature for product design. Three of these methodologies – Quality Function Deployment (QFD), Lean UX and Phase-Gate process – are compared. This paper aims to apply the concepts of Fuzzy Multi Attribute Decision Making (MADM) to choose the most appropriate design-making process for our design. Distance between two triangular fuzzy numbers is calculated by Hamming Distance and centroid-centroid distance method, which further applied to Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) for Fuzzy Numbers. Finally, to obtain preference ranking for the set of alternatives, Group Decision Making model is applied.
