address some of the key issues facing the existing retail supply chain management. It reminds of another requirement of SDP, that is, SDP is supposed to help address existing business operation problems in addition to offering new services and func- tions. In other words, SDP is also expected to help fix current unhealthy architec- ture or existing issues. From the perspective of telecom services and operations, SDP should be exam- ined from a general view of telecom development tendency, not only for future evolutions, but also existing integrations and disadvantages. 6.2.3 Telecom Frameworks Telecom frameworks undoubtedly play an important role in telecom operations. It usually involves with telecom architecture, various services, business process model, and SO on. The actual designation, deployment, and implement of telecom systems are supposed to keep pace with telecom frameworks which guide a progress vista for telecom markets. Regarding construction of IMS and SDP, it should also be one of those considerations, especially when it comes to telecom modeling. Reference [24] discussed "IMS/SDP ready" OSS/BSS as an example to use NGOSS principles in today's OSS/BSS projects. Several requirements indicated in the paper are proposed as follows [24]: Taking into account or interface all IMS/SDP architecture layers Manage multiservice ability Process complete order statuses from Customer Self-Service Portal/CRM to network Create and deploy services quicker than ever before Model Class of Service (CoS) at bandwidth level both during provisioning and assurance in order to manage IP capacity commercially Support E2E service-specific SLA/QoS guarantee and monitoring in accor- dance to the CoS Be inventory centric Use the NGOSS shared information data model Support flexibility and scalability Compliant with regulatory requirements such as emergency communication, security, and lawful interception Support integration or interoperability Overview of Cognitive NGSDP Model Another example is IBM Common Business Process Model
