Vodafone D2’s Next Generation Service Assurance program is the largest transformation project ever undertaken by the company as it moved from resource to customer-centric fault and service management. TM Forum’s Frameworx and Interface Program were crucial to the success of the project, which delivered savings of 47 percent in capital expenditure and 68 percent in operating expenditure. The biggest contribution to cost reduction was using the Forum’s Information Framework to calculate network alarms’ impact on customers, which yielded 40 percent savings. This has inspired the company to take part in the TM Forum Interface Program’s Resource Alarm Management development. In future, the company expects to save 30 percent in integration and customization costs, and is embarking on an even larger transformation project, building on the success of the original project.

NOSSIS uses TM Forum reference models: the Information Framework (SID), the Multi-Technology Network Model (MTNM), the Business Process Framework (eTOM) and the Application Framework (TAM). We chose to use TM Forum information models because they are standard and generic, and you can apply them with several network technologies including SDH, MPLS, IP and so on. They are independent and can be used equally for the IT world and telecoms, which is very important as one of our key objectives was to have a single mediation system for the telecom and IT networks to simplify reconciliation and to keep a centralized inventory for both worlds.
