This study focuses on a consumer-based design process that overcomes practical drawbacks of the previously used design process. On the contrary of the existing method of attracting design attributes by designers' own insights, it present the PRETREE model that attracts the important design attributes of the products based on consumer preferences. The PRETREE model has the advantage that it does not require identifying design attributes a priori. For the wire-wireless telephones, this study presents the identifying process the important design attributes empirically using PRETREE Model. The PRETREE Model has been widely used in the fields of psychology, consumer science, economics and business administration. It might also be useful in the design field because it can identify the important design attributes objectively without designers' own insights.
