The REFSQ conference has been promoting the application of empirical research methods to the exploration and evaluation of requirements engineering phenomena. As part of this, one of the traditions of the REFSQ conference is the organization of a special plenary session for conducting a “live study” involving the conference attendees on a voluntary basis. A live study could be a (controlled) experiment, a focus group, an interview-based study or an online survey related to requirement engineering.
Acknowledgements I am particularly grateful to the REFSQ 2019’s Programme Co-Chairs, Eric Knauss and Michael Goedicke, for including “Live Studies” in the overall REFSQ 2019 programme. I also thank all the members of the Live Study Programme Committee. Finally, we are much indebted to all the volunteer participants in the two studies. It is their expertise and insights into the subject matter that contributes to the authors’s efforts to answer the research questions posed in the two studies.
