Multimodel Application Specification, Integration, and Evolution - Experiences from the Reinsurance Industry

Swiss Re has established an architectural framework, tools, and concepts that enable business people to specify their view of the business in a consistent and formal manner. Based on repository technology, this business model is refined for each application. The architectural framework ensures that a specific list of integration and evolution problems are either solved or their complexity reduced. Our experience show that this generally yields very satisfactory results, but that the problems intrinsic to a large, globalized company (existence of legacy systems, different jurisdictions) are still felt strongly.
