Facing up to highly competitive telecom markets and fast evolutionary network technologies, Chunghwa Telecom (CHT) now re-engineers their business operation processes, accelerates new services delivery, and reduces operational and maintenance costs via the fulfillment of NGOSS (New Generation Operations Systems and Software). In this paper, we introduce CHT NGOSS practice and evolution process, which conforms to NGOSS development life cycle and methodology, including business requirements and execution planning, Shared Information/Data(SID) Model proposing, system implementation and deployment. A case study of alarm notification for multi-domain networks was given to discuss the CHT OSS/BSS development methodology used in NGOSS development life cycle.
