The purpose of this study is to identify the characteristics of Agile
development processes that impact user satisfaction. We used user reviews of
OSS smartphone apps and various data from version control systems to examine
the relationships, especially time-series correlations, between user
satisfaction and development metrics that are expected to be related to user
satisfaction. Although no metrics conclusively indicate an improved user
satisfaction, motivation of the development team, the ability to set
appropriate work units, the appropriateness of work rules, and the improvement
of code maintainability should be considered as they are correlated with
improved user satisfaction. In contrast, changes in the release frequency and
workload are not correlated
