Software and Systems Engineering addresses the central topics of software development and systems design: Methods, processes and practices for a systematic and well-structured development of software systems. The activities of a software engineer range from the first contact with the customer to work out the requirements for the system through requirements analysis, software architecture and object-oriented design to testing and maintenance. A wide variety of process models is available for different types of projects, ranging from agile methods (e.g. Scrum and Kanban) for smaller and more explorative projects to heavy-weight processes like the Unified Process or the V-Model for large and long-term system development efforts. Formulating artifacts in software development requires knowledge and understanding of different specification techniques like use-cases and UML diagrams as well as formal annotations like OCL. Software architecture, design patterns and the principles of object-oriented design are required to turn the customer’s requirements into a reliable, maintainable and sustainable design of the system. Systems engineering focuses on the specifics of analyzing and designing heterogeneous system landscapes. It deals with coupling software with its environment which can be an enterprise application landscape (Enterprise Application Integration) as well as special hardware (Embedded Software, hardware-software-codesign). These integrated systems often have special requirements emerging from the system as a whole. We are dealing with all these aspects of software and systems engineering in our teaching and offer knowledge-transfer and consulting as well as joint research efforts on all these topics. Our research focuses on modeling techniques and languages for security and safety, software development for self-organizing (OC-) systems and component-oriented software development.

The goal of our research is to enhance the state-of-the-art in Software and Systems Engineering to have applications with higher quality in a shorter time.
Our manifold research activities include:

• SAVE ORCA?deals with the systematic design of reliable Organic Computing applications and offers a development guideline for such systems
• Secure-MDD?develops a model-driven method for the design and implementation of security-critical systems
• GO!Card?combined formal and semi-formal methods into a rigorous development process for secure smartcard applications
• SoftRobot?developed a new software architecture for controlling industrial robots
