Digital Enterprise Architecture

Research Group

Alfred Zimmermann

Prof. Dr. rer. nat. Alfred Zimmermann

Alfred Zimmermann is Professor of Digital Enterprise Architecture in the Faculty of Informatics at Reutlingen University. He is the research director of the Herman Hollerith Center Böblingen and speaker of the Cooperative Doctoral Program Services Computing at the Herman Hollerith Center Böblingen. His research focuses on digital transformation and intelligent digital architectures with multi-perspective decision support, in close connection with digital strategy & governance, software architecture, artificial intelligence and cognitive architecture, data analytics, Internet of Things, service computing, and cloud computing. Professor Zimmermann supervises PhD students in joint research programs with universities such as Stuttgart, Rostock, and Leipzig. He also supports international research programs and research partnerships with universities in Europe, Japan, USA, Canada, and Australia. Professor Zimmermann graduated in Medical Informatics from the University of Heidelberg and received his PhD in Computer Science from the University of Stuttgart. In addition to his academic experience, he has a strong practical background as a technology manager and leading consultant at Daimler AG, Germany. Alfred Zimmermann is active in international networks and as co-organizer of several workshops and conferences, as well as conference chair of the international HCIS - Human-Centered Intelligent Systems, and as editor and author of books, journal and conference papers.

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.

COLUMBUS @ planningIT
Columbus Reisen describes an application scenario of a virtual travel agency for a reference implementation of architecture concepts and relationships of Enterprise Architecture Management (EAM) models with the EAM tool planningIT. The created implementation serves as a research and experimental environment for reference models and reference architectures of EAM to be explored.

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 Services Architecture, Security Architecture.
