Abstract
The divergence and convergence of ideas is one of the most important processes in the general design process, not only in UX design. In particular, idea convergence is the process of narrowing down the design candidates for actual implementation, and it is necessary to select effective ideas effectively. However, there is currently no way to converge ideas specific to UX design. In addition, a survey the authors conducted with UX designers revealed a number of problems with the way ideas converge. Therefore, this study investigates a suitable method for idea convergence in the UX design process. First, we conduct a comparative analysis of the four existing idea convergence methods. After that, we will experiment with the Pugh Concept Selection to apply it to UX design and examine the issues when applying it.
