The Sustainability of Quality in Free and Open Source Software

We learned from the history of software that great software are the ones who manage to sustain their quality. Free and open source software (FOSS) has become a serious software supply channel. However, trust on FOSS products is still an issue. Quality is a trait that enhances trust. In my study, I investigate the following question: how do FOSS communities sustain their software quality? I argue that human and social factors contribute to the sustainability of quality in FOSS communities. Amongst these factors are: the motivation of participants, robust governance style for the software change process, and the exercise of good practices in the pull requests evaluation process.
