As one of the measures, a method has been proposed to support the design and evaluation of rules that take into account the mechanism of functional performance of rules. However, an evaluation including understandability and usability of the method has not yet been conducted. Therefore, the purpose of this study is to evaluate a method to support the design and evaluation of rules that take into account the mechanism of functional performance including the perspectives of understandability and usability. To evaluate the method, we conducted user evaluations using questionnaires on the method and the results of the method, experiments to compare the method with another method, and third-party evaluations by the regulated persons, and identified several problems with understandability and usability. We explain our results and conclusions of this study and our future research topics, including problems of the method, in the last part of the paper.</p> NAOKI OKAMOTO Yoshiko Ohno Fumihito Oura Seiko Shirasaka Copyright (c) 2025 International Journal of Service and Knowledge Management 2025-06-08 2025-06-08 9 1 10.52731/ijskm.v9.i1.864
