The financial and insurance sector is characterized by business processes that are largely automated, but are also intermittently interrupted in some places by a required manual employee interaction. This provokes a certain complexity in handling those automated processes. Compared to other sectors, the financial and insurance sector has recognized the potential of IT-solutions for the automation of business processes and applications in early stages. These are standardized within the VAA, a German standard for the architecture of insurance application. This standard refers to a functional and object-oriented perspective. The service-oriented perspective is not yet available. Often, the historically business growth has led to cumbersome and undefined software monoliths, which have not yet been modernized by the use of service-oriented architectures. In the context of this contribution, the service-oriented perspective is also taken up against the functional and object-oriented perspective in order to enable a modern way of handling complex business processes. Therefore, existing processes from the insurance industry are systematically analyzed and formalized in order to break them down into individual services. The disassembly of those processes into lightweight and reusable services offers the transformation from a functional or object-oriented architecture to a modern service-oriented architecture. Furthermore, service dependencies arising in this context are analyzed and examined in this contribution. This allows identification of reusable workflow control patterns in future work.
