Prof Dr. Ralf Reussner holds the chair of Software Design and Quality at the Karlsruhe Institute of Technology (KIT). Since 2006, he is director at the FZI – Forschungszentrum Informatik in Karlsruhe and since 2011 member of the Board of Scientific Directors. He was founder and first head of the GI Chapter on Software Architecture. Since 2015, he is head of the coordination board of the DFG Priority Programme 1593. His research interests include, among others, component-based software engineering, quality attributes of software, software design, and software architectures.Prof. Dr. Michael Goedicke is head of the working group “Specification of Software Systems” at the University of Duisburg-Essen. He is vice president of the GI and Chair of the Technical Assembly of the IFIP. His research interests include, among others, software engineering methods, technical specification and realization of software systems, and software architecture and modelling.Prof. Dr. Wilhelm Hasselbring holds the chair of Software Engineering at Kiel University since 2008. From 2000 to 2008 he headed the Chair of Software Engineering at the University of Oldenburg. In the competence cluster Software Systems Engineering (KoSSE), he coordinates technology transfer projects with industry. His research interests include, among others, distributed systems, software quality and software architectures.Prof. Dr. Birgit Vogel-Heuser is head of the Institute of Automation and Information Systems at the Technical University of Munich. 10 years in industry and more than 15 years in academia provided her with significant experience in software engineering for machine and plant manufacturing. Her research interests include, among others, modelling of distributed embedded systems in automation and system and software evolution of automated production systems (aPS). Such aPS are complex mechatronic systemsthat often undergo innovations as addressed in the CRC 768 she is speaker of.Jan Keim is researcher at the chair of Architecture-driven Requirements Engineering at the Karlsruhe Institute of Technology (KIT). He is managing director of the DFG Priority Programme 1593 where he, among others, promoted collaborations within the programme by coordinated joint-activities like workshops. His research interests include software architecture documentation and natural language understanding.Dr. Lukas Märtin holds a Ph.D. from the Karlsruhe Institute of Technology (KIT). His thesis examines the predictive assessment of feasible design options to support cost-efficient decision support in reconfiguring software-intensive technical systems with limited maintenance access. As managing director of the DFG Priority Programme 1593 in both funding periods, he promoted collaborations within the programme by coordinated joint-activities until summer 2018.
