This manuscript presents a methodology to mathematically calculate the relation between the technical customer requirements and the technical product characteristics. This methodology is used to fill the house of quality tool of the quality function deployment method during the product design and development. In addition, the critical to quality characteristics of the product are identified. Further, the direction of optimization of the characteristics is determined. The sensitivity method is used to calculate the relations namely the elements of the transfer matrix by means of an analytical model of the product. The proposed method is applied to a model of a Segway consisting of kinematic/dynamic relations as well as actuation and control unit models.

Keywords: QFD, Requirements, Sensitivity analysis, New product development, Product modelling / models
