Current technologies and market dynamics are forcing telecom operators to shift business approach to top-down (meaning creation of services on network) from the current practice of bottom-up approach (services created over a network). Service providers, both Communications and Managed Services, are increasingly looking towards an integrated NMS from a service management perspective, meaning that the customer care process may escalate a service problem to the NOC. Thus the NMS must have some mechanism for correlating services with network conditions.

In this evolving process, the service providers face challenges in supporting their Network Operations Center (NOC). Key issues faced are

1. Disparate management systems from multi-vendor or multi-technology rendering it difficult to correlate and accurately pinpoint the reason for a service or network failure quickly
2. Proprietary management systems hinders ability to co-operate with existing or planned OSS/BSS
3. Specialized requirements like integration of legacy infrastructure with proprietary interfaces
4. Existing framework solutions are not cost-effective and time consuming for customization. Point solutions are fragmented and tedious to integrate with each other.
