製品の使用価値向上を支援する行為品質の可視化手法

抄録

As the focus of product value shifts from value-in-exchange to value-in-use, assessing value-in-use becomes essential for enhancing product design. However, value-in-use varies among users, changes dynamically during use, and is perceived across multiple dimensions, making it challenging to capture value-in-use comprehensively. To address this challenge, this study conceptualizes use action quality as one of evaluation criteria for value-in-use and develops a method to evaluate and visualize use action quality, taking into account of heterogeneity, changeability, and multidimensional nature. The proposed method was applied in a case study, demonstrating its validity and usefulness.
