Of many kinds of developer metrics proposed, developer quality is important. Recently, some researchers measure a developer's quality as the rate of his/hernon bug-introducing commits. In this paper, we conduct an empirical study of this developer quality metric. We use the data of six open source software projects and get the following conclusions: (1) the values of developer quality in a project are uniformly distributed in a certain range, (2) developer quality tends to increase with software evolution, (3) developers with more contribution are more likely to have higher developer quality, (4) ownership does not have a consistent and significant correlation with developer quality. These results can provide project leaders and team members with some guides to improve developer quality, and thus improve software quality. %B 2015 International Conference on Software Quality, Reliability and Security - Companion (QRS-C) %I IEEE %C Vancouver, BC, Canada %P 202 - 209 %8 08/2015 %R 10.1109/QRS-C.2015.33
