Living Modeling of IT Architectures: Challenges and Solutions

Enterprise Architecture Models (EA Models) are documentations capturing the elements of an enterprise’s IT infrastructure, setting these elements in relation to each other and setting them into the context of the business. EA Models are a crucial backbone for any IT management process and activities like analysing IT related risks and planning investments. The more companies depend on reliable IT services and use IT as innovation driver, the more high quality EA Models provide competitive advantage. In this paper we describe core challenges to the maintenance of EA Models based on previously conducted surveys and our longstanding experience in industrial collaborations. This is followed by a sketch of an innovative solution to solve these challenges.
