Introduce to "Usability-quality Product Development Technology (UPDT) ": Taking the Design of Desk and Chair as an Example

Abstract This study refers to the "Usability-quality Product Development Technology (UPDT)", and explains the feasibility of UPDT by a case study of desk and chair design. The UPDT method is a new product development technology that combines "Focus Group" and "QFD (Quality Function Deployment)". Among them, the focus group method is mainly used to investigate and organize the consumers product use requirements, while the QFD is used to convert the consumers product use requirements into specific designs and ensure product quality. This study will use the desk and chair design as an example to illustrate the feasibility of the UPDT method. The research results show that the UPDT method can be used to develop products with usable quality. Based on this, this study suggests that the UPDT method can be used as one of the technologies for new product development.
