Service-oriented architectures focus on the alignment of business processes and the supporting information technology. To facilitate the alignment and to decrease administration costs we propose linking of SOA services to enterprise models respectively target state organisational models by using semantically enriched conceptual modelling languages. Acting on language meta-level means in this context the introduction of service related constructs into widely used visual modelling grammars. Vision is the situation dependent adaptation of software functionality to the actual business process requirements. An efficient adaptation is crucial in order to be able to respond quickly to environmental or system induced change.
