Increasing competition and the convergence of networks and devices dictates that to differentiate their offerings, Communications Services Providers (CSPs) must manage an ever more sophisticated and broad set of services. Whether it be fixed operators launching mobile and convergent services, mobile operators adding broadband to their portfolios, or new virtual operators re-selling a full suite of telecoms and content services, it is essential that the complex portfolio of service capabilities are transformed into easy to order and simple to use products. Legacy OSS and BSS silos designed for a single service type, slow down new service rollouts and inhibit service flexibility, leaving operators at the mercy of their more agile competitors. In this environment, being able to efficiently manage the complete service lifecycle, from network capability and service creation, to customer order and service personalisation, is one of the critical factors for on-going operator success.
