configuration and network or resource provisioning/configura- tion. In resource provisioning, the order details are converted to resource level requirements that need to be configured and activated. Network provisioning and configuration module works on the resource level requirements to con- figure the resource identified by the inventory management module to offer a specific service. The provisioning and configuration module has multiple interactions with inventory management module. Hence it is important to make these two applications interoperable. After completing provisioning and configuration of network resources, the provisioning application updates information on the status of the resources with inventory application. Some applications also support creation of resource configuration plan. This plan has details of the required resource actions that can be sent to an orchestration to trigger auto provisioning and configuration of resources. 50. Specification management: These applications are used for creating, editing, storing, and retrieving specifications. Specifications can be at the service level, capability level, and resource level. Service specifications deal with the service attributes and its values that are common across a specific set of services. Resource specifications will have technical details on the layout, attributes, and connection parameters of the resource. General characteristics across the resource that can be realized in multiple resource instances make up capabil- ity specifications. The specification management application can be used to create new service instances from the service specifications. Capability specifications Fundamentals of EMS, NMS and OSS/BSS can be accessed from specification management applications to perform strategic planning and implementation planning. The resource specifications are retrieved from specification management application for the creation of resource instance that comply to the specification. 51.
