Aligning Service Maps - A Methodological Approach from the Financial Industry

摘要

Service-orientation is commonly recognized as an important enabler for improved efficiency and flexibility of transformation processes in business. The ability to flexibly bundle heterogeneous services in a homogeneous cross-organizational business process is a key requirement. Shared service models may be one approach to overcome the restrictions of existing approaches which are either business process centric or application centric. Nevertheless applying different design approaches increases the risk of the emergence of service-oriented-architectures (SOA) implying heterogeneous service maps. Especially the design of service maps on different layers leads to significant integration efforts in practice. This paper presents an approach how service maps that differ in scope, granularity and design may be integrated. A case of a Swiss bank has been chosen to demonstrate the applicability of the suggested model.
