Beschreibung

Today, virtually all large organizations have to cope with growing complexity in their enterprise architectures (EA), which often comprise several hundreds or even thousands of IT applications that support an increasing variety of business processes. The underlying software components run on several generations of IT infrastructure, and digitization leads to increased intensity in inter-organizational interfaces and customer-centric solutions. As a consequence, EA comprises not only the fundamental structure and dependencies of business processes, IT applications, software components, IT infrastructure, and data in an enterprise, but also connected components of business ecosystem partners and customers. Changing only one of these EA components can impact a potentially large number of related components. Simultaneously changing several of these components in a number of change projects or transformation programs leads to potentially redundant (i.e. inefficient) and/or inconsistent processes, software systems, and/or IT infrastructure components. The short-term consequence is a waste of resources, and the longer-term consequences are increased effort and difficulty in maintaining existing information systems (because of excessive complexity) and shortage of resources that can be used for innovation.

EA management (EAM) is a management discipline that guides EA’s design and evolution. The goals of EAM are to control complexity, reduce inconsistencies, and leverage synergies in EA. EAM also supports the implementation of business innovation from a holistic perspective.
This course covers EA and EAM, incorporating both research findings and current examples from business practice. The course covers four primary topics:

  • Core concepts and the necessity of EAM
  • EAM use cases
  • EA modelling and analysis
  • Continuous improvement and maturity of EAM

Lernergebnisse

After successful completion of the course, students will:

  • understand the fundamentals of EAM
  • understand EA’s complexity and know how to align the components in an EA and how to align EA with organisational strategies and structures
  • be able to use methods for modelling, analysing, and improving EA
  • be able to evaluate the consistency, fit, and effectiveness of EAM initiatives in organizations

Kompetenzen

Lehrmethoden

  • The course involves interactive lectures, class room exercises, and practitioner presentations to integrate theoretical knowledge with practical design and analysis skills.
  • The e-learning platform Moodle is used throughout the course to disseminate course materials and for information and discussion.
  • Case studies are used to integrate the aspects of EA/EAM covered in the course.
  • Students complete homework assignments between lectures.
