The REFSQ working conference is the leading European conference series on requirements engineering. It is the goal of REFSQ to foster the creation of a strong European RE community across industry and academia. Since 1994, Requirements Engineering continued to be a dominant factor influencing the quality of software, systems and services. REFSQ seeks contributions which report on novel ideas and techniques that enhance the quality of RE’s products and processes, as well as reflections on current research. REFSQ has a long tradition of being a highly structured and interactive forum. The special format of each session includes the three roles presenter, discussant, and session chair, yielding into highly interactive sessions, filled with discussions among the excellent researchers and industry experts. In addition to the high-quality scientific program, REFSQ also features a highly interactive Industry Track, Workshops, Posters and Tool demos, Doctoral Symposium and a Live Study Track.
