Teaching assistants


Master: Informatics, ITMC, Intelligent Adaptive Systems, Information Systems.
This course is part of the module “Empirical Software Engineering”.


The lecture “Software Patterns” deals with the topic Software Engineering Knowledge using empirical, experience-based patterns to solve typical recurring problems in software projects. This applies to both classic design patterns (patterns and anti-patterns), which are known in the field of Software Architecture, as well as modern, domain- and task-specific patterns such as process and project management patterns, or usability patterns.


  • Basic knowledge in empirical methods and how they can be applied in the field of software engineering
  • Current topics in experience-based software patterns
  • Insights about the state of the art and current research topics in software engineering
