The rapid changing of business environments requires state of the art software engineering methods, which support integration, reusability, loose coupling, extensibility and interoperability. Since Service-Oriented Architecture (SOA) provides these requirements, this paper proposes the service portfolio of an Enterprise Resource Planning (ERP), which accommodates the Information Technology (IT)-related business goal, i.e. creates agility in responding to changing business requirements, and also facilitates the functionalities in a commonly standard ERP. The service portfolio provides three levels of views, which are the conceptual view, the logical view, and the physical view.
