Digital Enterprise Architecture

Research Group

Alfred Zimmermann

Prof. Dr. rer. nat. Alfred Zimmermann

Alfred Zimmermann is a professor of software architecture and digital enterprise architecture at the Faculty of Computer Science at the Reutlingen University of Applied Sciences. He is the Research Director of the Herman Hollerith Center for Services Computing Böblingen and Coordinator of Research at the Faculty of Computer Science. Professor Zimmermann supervises doctoral students in joint research programs with universities such as Leipzig, Rostock, Stuttgart and Tübingen. He supports various research programs with international partners such as the University of West Florida, the University of West of Scotland, CMU's Software Engineering Institute (SEI), and maintains research partnerships with well-known companies and other scientists. He coordinates the academic relationships of his home school to the GI Society for Computer Science, the ACM - US Association for Computing Machinery and IEEE, where he is part of specific working groups, programs and research initiatives: software architecture, enterprise architecture & management, services computing, Cloud computing, and semantics. He is also a guest professor and honorary professor at international universities: University of La Plata - Buenos Aires, the Marmara University and the Yeditepe University of Istanbul. He received his diploma in the field of medical informatics at the University of Heidelberg and promoted in Computer Science at the University of Stuttgart. Dr. Zimmermann was Senior Consultant for New Software Technologies at Daimler AG Stuttgart until 1998. Since 1986, he has been responsible for the first object-oriented strategies and strategic projects as well as complex, partly international software development programs within and outside the Daimler Group as well as with well-known partners.

The research group Digital Enterprise Architecture is working together with doctorates and excellent partners from science and industry in the field of digital enterprise architecture. This research is linked to basic Internet architectures for services & cloud computing, mobility and big data in the context of collaborative processes Application Scenario SmartLife.

We dedicate ourselves to cooperative research and work on selected innovation topics in the field of digital enterprise architecture & management, methods and technologies. Research in these areas provides an effective contribution to excellent academic teaching and research programs for services computing and digital business at the Herman Hollerith Center.

The result of our research work is a series of original architectures with associated methods and instruments for powerful innovative architectures for an integrated business with forward-looking information systems. In addition, we focus on the further development of the basics in topics such as software engineering and quality management, architecture metamodels, ontologies and semantics-based architectures and information systems, architecture reference models, frameworks and patterns as well as methods for architectural analysis, optimization of architectures and maturity assessment diagnostics Of architectures.

We are part of the academic discussion at national and international conferences and in addition to the role of authors, management functions in organization and program committees and the coordination of scientific workcourses and specialist groups.


A list of all current publications of the research group can be found in the University bibliography.


The course offers a collection of lectures with integrated research studies as well as a free spectrum of elective subjects derived from current research projects.

Mobile App for visual analysis of corporate architectures
Conception and implementation of interactive visualizations for the analysis of complex structures in the form of a platform-independent app for mobile devices. In practice, tools are often used whose visualization capabilities have traditionally been shaped. Modern technologies for implementing interactive visualizations are rare. By developing a prototype, modern visualization forms are to be implemented and evaluated for the analysis of corporate architectures.

ESARC - Reference Model and Ontology for Enterprise Architecture Management (EAM)
A holistic model for the classification of EAM architectureviews and viewpoints is to be developed and validated. The following architecture dimensions of the EAM are to be supported: Architectural Governance, Architecture Management, Architecture Analytics, Architecture Engineering, Business & Information Architecture, Information Systems Architecture, Technology Architecture, Cloud Architecture, Security Architecture.
