REFSQ 2015 encouraged researchers and practitioners from the research fields covered by the conference to submit posters. The poster track at REFSQ15 is intended to provide a forum for presenting recent work and obtaining early feedback on ongoing research. All submissions were reviewed by at least three members of the program committee. In the end, five posters were accepted for display, addressing the following topics: - A Framework for Information Quality Requirements Engineering - Motivation as a Supplementary Requirement - Transparency as a Requirement - Digital Addiction: Gamification for Precautionary and Recovery Requirements - Integrating GUI Mockups and User Stories In addition to the poster presentations during the conference, two-page abstracts are included on the following pages in the Joint Proceedings for Workshops, Research Method and Poster Track of REFSQ 2015. To increase the visibility of the work, a poster slam was included in the conference program just after the first keynote. The posters will be on display in the co↵ee hall during the conference.
