This workshop focusses on the interplay of user experience (UX) and user-centered development processes of interactive systems. It is organized by the IFIP Working Group 13.2 on Human-Centered Software Methodologies. It is proposed as a follow-up activity started at an interactive session organized at HCSE 2014. Our ultimate goal is bringing together researchers and practitioners to discuss real-life case studies featuring success and/or failure stories of development processes that take into account UX as an important dimension for the interactive system at concern. Based on these discussions, we expect to deepen the understanding of problems and challenges when dealing with UX in the software development process.
