Studiengänge & Module

IT-Systems Engineering BA


Companies benefit from using concepts, methods, and techniques of Business Process Management by improving their operations. All of the company’s business processes follow a life cycle that comprises the phases of design & analysis, configuration, enactment, and evaluation. In each of these phases process quality and architectures comes into play.

This course is split up in different clusters:

Process Monitoring

Process Monitoring is a central discipline to find out what quality a process provides. This includes measuring of process instances and their activities, respectively extracting such data from various IT systems, e.g. workflow systems. Representation/transformation of this data in process models offers multifaceted research questions.

Topic in this field are:

  • How to Model Measurement/Event-capturing Points in BPMN Models
  • Techniques to Learn about Human Actions during Process Execution
  • Exception Handling for Events
  • Analytical Process Simulation Techniques (Literature Review)
  • Visualization Techniques in Monitoring


Process Similarity Search

As Business Process Management became one major driver in nowaday's companies, process model repositories emerged that contain hundreds or thousands of process models. They carry a central asset of the business. However, to use them effectively requires capabilities to efficiently manage these models, in particular means to find process models.

The area of process model similarity search focusses on this problem. Similarity of process models can be based on different aspects, i.e., structure and behavior. Search for similar process models in a repository requires a query model and a search radius that specifies how similar a model of the search result shall be to the query. As their is no natural or meaningful ordering among the structure or behavior of models, one can either resort to sequential search, i.e., compare the query with each and every model in the repository, or leverage efficient index structures and search algorithms in metric spaces.

The proposed topics in this field do not directly address such indexing approaches, but rather focus on foundations of similarity and how search results can be qualitatively evaluated.

Topics in this field are:

  • Quality Measures for Search Results
  • Existing Similarity Measures (Literature Review)
  • Process Model Alignment


Process Quality and Architectures in General

Process quality and architectures are a major topics in process-oriented companies as well as in research. There are a lot of approaches targeting on measure and increase quality of processes and to build-up high-valuable process architectures. Around process quality and architectures in general the source touches following topi

  • Survey of Process Architectures and Process Navigation
  • Process Model and Data Extraction from Application Forms in the Public Sector
  • Towards Canonical Process Models
  • IT-Services to Business Process Alignment
  • Modeling Guidelines for BPMN 2.0


The detailed information about the topics can be found at the seminar web page.
