Integrated and Iterative Systems Engineering and Software Requirements Engineering for Technical Systems (Précis) Holtmann, Jörg Bernijazov, Ruslan Meyer, Matthias Schmelter, David Tschirner, Christian Jürjens, Jan Schneider, Kurt The development of software-intensive technical systems (e.g., within the automotive industry) involves several engineering disciplines like mechanical, electrical, control, and particularly software engineering. Model-based Systems Engineering (MBSE) coordinates these disciplines throughout the development by means of a discipline-spanning system model. An integral part of MBSE is the requirements engineering on the system level. However, these requirements need to be refined for the discipline-specific development to start, for example, into specific requirements for the embedded software. Since existing MBSE approaches lack support for this refinement step, we conceived a systematic and iterative transition from MBSE to model-based software requirements engineering, which we present in this talk. We automated the steps of the transition where possible, in order to avoid error-prone and time-consuming manual tasks. We illustrate the approach and perform a case study with an example of an automotive embedded system.
