SID uses UML to define entities and the relationships between them. The benefit of using the NGOSS SID and its common informa- tion language is that it offers business benefits by reducing cost, improving qual- ity, reduced timeliness for delivery, and adaptability of enterprise operations. Use of SID allows an enterprise to focus on value creation for its customers. Even the attributes and processes that make up the entity or object are modeled with UML. SID provides a knowledge base that is used to describe the behavior and structure of business entities as well as their collaborations and interactions. SID acts as an information/data reference model for both business as well as systems. SID provides business-oriented UML class models, as well as design- oriented UML class models and sequence diagrams to provide a common view of the information and data. Mapping of information/data for business concepts and their characteristics and relationships can be achieved when SID is used in combination with the eTOM business process. SID can be used to create cases and contracts to the four views: business, system, implementation, and deployment in the NGOSS lifecycle. SID has both a business view and a system view. The SID framework is split into a set of domains. The business view domains include market/sales, product, customer, service, resource, supplier/part
