Abstract
Due to the specialization and professionalization of design work, sharing product information between members of a product development team is a crucial aspect of the design process. One method to effectively share information between members is Quality Function Deployment (QFD), which uses quality charts to describe the relationships between design elements. This paper proposes new type of QFD on the basis of the multispace design model, Interpretive Structural Modeling (ISM), and Design Structure Matrix (DSM). The proposed QFD (called multispace QFD ) allows designers to extract design elements with respect to diverse requirements and give design information (designer's idea) to other designers and enables them to easily construct a process of redesign or design change without an inadequate designing order causing the design reconsideration. Additionally, a design example is presented to demonstrate the proposed M-QFD.
