Abstract

In this study, we investigate usability issues in developing an expert network platform, providing valuable insights through agile testing and quantita-tive analysis compared to traditional expert qualitative methods. Simple usability tests conducted with college students revealed various problems related to User Experience (UX). Using Social Network Analysis (SNA), we identified 13 dis-tinct clusters of issues. Through more detailed network analysis, we emphasized the importance of precise descriptions, consistent terminology, improved acces-sibility, and UI enhancements that increase reliability, professionalism, under-standability, and intuitiveness. By comparing the SNA results with expert quali-tative analysis using the KJ method, this study demonstrates that simple, cost-effective testing can effectively identify usability issues and provide actionable insights. This approach allows small and medium-sized enterprises (SMEs) to enhance their platforms without extensive expert intervention. Future research should involve a more diverse range of user groups to refine these findings further and ensure that the platform adequately meets the needs of all potential users. By doing so, we aim to develop a more comprehensive understanding of the usability challenges.
