In the development of safety- and security-relevant systems the V-model is established providing verification possibilities at each development stage. Usually, methods and tools of Model-based Systems Engineering (MBSE) are used in combination with the V-model for the development of single and self-contained complex systems. Nowadays, ubiquitous connectivity leads to a high degree of communication between systems enabling their cooperation for the provision of new services in a so-called System of Systems (SoS). In contrast to conventional systems engineering new methods and tools are required for service enabling SoS. In order to fulfill requirements of System of Systems Engineering (SoSE) the Object Management Group (OMG) developed the Unified Architecture Framework (UAF) for representation of enterprise architecture. This paper presents an approach for model-based development of SoS using UAF according to the V-model. In addition, an application of this new method shows differences between single system and SoS development methods.
