A Service Portfolio for an Enterprise Resource Planning
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.
