It is shown how a service-oriented and model-based approach for Enterprise Architecture and Enterprise Engineering can provide agile support for the different abstraction and modeling levels from business model and service innovation to cloud-based service realisation. Business model innovation is supported with a basis in a business model framework with six views, where each view is supported by a corresponding diagram from the Value Delivery Modeling Language (VDML). Service innovation is supported by the Service Modeling Language (ServiceML), which shares the core collaboration models of VDML for role modeling and value networks, according to the five views of the AT-ONE service innovation method. Service realisation is supported by further transformation to SoaML and a model-based service execution platform. This approach presents a framework using the emerging OMG standard language VDML together with ServiceML for service design and engineering, relating value models, process models, user interface and interaction flow models, and service architectures and service contract models.
