QUALITY FUNCTION DEPLOYMENT BASED ON THE MULTISPACE DESIGN MODEL

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 QFD comprised of four deployment charts, which correspond to the four space concepts (value, meaning, state, and attribute) based on the multispace design model. The proposed QFD allows designers to extract design elements with respect to diverse requirements and promotes bidirectional deployments of the design elements. That is helpful to design entirely new products. Additionally, a design example is presented to demonstrate the proposed QFD.
