Model-Driven Engineering (MDE) mixes up manual activities, like coding or modeling, with automated activities, such as transformation or generation steps, which can lead to constraints on the development process. Currently, we know little about such constraints. For gaining more knowledge about this it is necessary to capture and compare MDE activities from practice to identify reoccurring structures that can be associated to constraints on the software development process. However, current techniques to capture MDE activities are not sufficient for comparison. Therefore, we developed a new approach to characterize activities based on relations between consumed and produced artifacts. Further, we evaluated this approach by applying it to activities from industrial case studies. Thereby, we found that our approach is applicable to capture complex industrial activities and that the identification of reoccurring structures is possible. These results enable future research about the influence of MDE activities on software development processes.

The next generation of advanced mechatronic systems is expected to enhance their functionality and improve their performance by context-dependent behavior. Therefore, these systems require to represent information about the complex environment and changing sets of collaboration partners internally. This requirement is in contrast to the usually assumed static structures for embedded systems. In this paper, we present a model-driven approach which overcomes this situation by supporting dynamic data structures while still guaranteeing that valid worst-case execution times can be derived. It supports a flexible resource management which avoids to operate with the prohibitive coarse worst-case boundaries but instead supports to run applications in different profiles which guarantee different resource requirements and put unused resources in a profile at other applications' disposal. By supporting the proper estimation of worst case execution time (WCET) and worst case number of iteration (WCNI) at runtime, we can further support to create new profiles, add or remove them at runtime in order to minimize the over-approximation of the resource consumption resulting from the dynamic data structures required for the outlined class of advanced systems.

In this tool demonstration we present an implementation for interactively validating requirements for multi-user software systems and the processes they support with end users. The tool combines the advantages of requirements animation and scenario synthesis to gather stakeholder feedback and create a common understanding amongst stakeholders. Additionally, the users' behavior during the simulation is captured and used to automatically derive new behavioral specifications.

Based on a well-defined component architecture the tool supports the synthesis of so-called real-time statecharts from timed sequence diagrams. The two step synthesis process addresses the existing scalability problems by a proper decomposition and allows the user to define particular restrictions on the resulting statecharts.
