Service-Oriented Business Ecosystems (SOBEs) contain numerous procedures and rules that act upon services, but are not considered to be servic-es themselves. Thus an asymmetry is created by dividing SOBEs into first-class entities that are services and others that are not. This separation creates ineffi-ciency and conceals the value contribution of non-first-class entities. Using so-called meta-services it is possible to encapsulate procedures and rules homoge-neously as services, thus creating a symmetric architecture of the SOBE. This symmetric architecture allows reducing the administrative effort for SOBEs by reusing procedures and using a common administration for services and meta-services. Meta-services are a value factor often underestimated by service de-signers, but highly appreciated by service users. By defining meta-services, the possible interactions between customer and service provider can be defined clearly, including mutual expectations. E.g. it is possible to define the informa-tion due in the case of a complaint. Furthermore, meta-services allow to clarify the potential adaptations to changing requirements to the customer and thus to delineate the spectrum of flexibility offered. The transparency created by meta-services allows defining contracts in a more precise manner and thereby avoid-ing misunderstandings and deceptions on both sides.
