Abstract: Agile software development (ASD) methods, currently the primary development approach, use various metrics for quality management. However, few existing research studies directly measure the ASD process improving user satisfaction even though the user is the top priority in ASD. Therefore, this study aims to identify the ASD processes that affect user satisfaction with open-source software (OSS). We construct an information system named AS-ASD, which examines the relationships, especially time-series correlations, between ASD process metrics calculated by issues and pull requests in GitHub and user satisfaction calculated by user reviews in the Google Play Store. As a result, we found a correlation between issues processing time and user satisfaction but did not find a correlation between velocity and user satisfaction. These results, supported by quantitative analysis of user reviews, suggest that ASD processes that actively detect and address user feedback, as well as those capable of responding swiftly to user concerns, affect user satisfaction.
