Analysis System of Agile Software Development Process Metrics and User Satisfaction

Agile software development (ASD) methods which are currently the primary development approach, use various metrics for quality management. However, few existing research studies directly measure improvements in user satisfaction as a result of the ASD process, even though the user is the top priority in ASD. Thus, it is important to identify those ASD processes that affect user satisfaction. To support such analysis, we constructed an information system, AS-ASD, which examines relationships between time-series ASD process metrics calculated on the basis of issues and pull requests in GitHub and user satisfaction calculated on the basis of user reviews. A case study evaluated AS-ASD to open-source software (OSS) development, which follows the same lines of thought and practices as ASD methods. The results revealed a correlation between issues processing time and user satisfaction, but no significant correlation between velocity and user satisfaction. These findings, 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 can improve user satisfaction.
