This dissertation examines the effects on the enterprise landscape caused by interface changes. Heterogeneous systems are the big challenge, as well as creating successful IT supported businesses. Interface technology allows companies to interact with their suppliers in real-time, implement fully automatic customer data transfer, and exchange employee's data between authorities - integration is the key to all these scenarios. There are lots of questions that arise: How can companies keep an overview of all their interfaces and data flows? Can implementation costs of the interfaces be reduced? How can potential risks be recognized? The current research of enterprise architecture management considers only whole-system landscapes and their relationship to the business processes. In this perspective, the details are limited to systems. Interfaces are addressed only as part of an IT system, rather than considering them as subsystems. This also takes place when we look at the lifecycle of a system. System lifecycle management stops at the system level, leaving interfaces underappreciated despite the increasingly significant role they have in today's world. Thus, a model with a strong focus on interfaces was created. It presents the typical lifecycle of an interface, in addition to its interaction with other interfaces within the enterprise landscape. The basis for this model is the interface catalogue, which can be used as an artifact to document and monitor the interfaces of a system landscape. The catalogue enables managers and IT staff to analyze the impact of changes on the interface level. Furthermore, corresponding KPI can be derived. The catalogue and the usage of KPI could be explained by two case studies at companies in the manufacturing and logistics sectors.
