摘要：Users’ requirements are key factor for optimizing the design of products. It could be classified into two groups: qualitative research work and quantitative research work. Wireless internet terminal equipment could be used as one example to further study the qualitative research work of requirements. FBS guided by users’ requirements was discussed. The users centered service designing process model was established through the analysis of users’ needs (Ra) in the function of design, use-pattern, delivery and transformation. Based on this work, the relation between users’ needs and requirements of the design was set up. The completely research work about transformation of users’ needs to design requirements was discussed in this study, and finally a wireless terminal equipment was used as a case study to verify this method.
