                Management Gaps
•   Lack of automated and proactive end-to-end service assurance
     – Leads to poor customer service, resulting in high customer churn
     – Little return on effort invested in definition of specifications in terms of
       standard product
     – Inability to proactively prompt customers/trading partners of service
       faults/failure
•   Lack of integrated network and service level OSS solutions
     – Requires substantial investment by service providers in system integration
       instead of delivering unique service offerings
     – Cost of ownership associated with several non-integrated EMS/NMS/OSS
       functions from various vendors
•   Lack of real time notification of service affecting problems to the
    Customer Care system from multi-technology, multi-vendor networks
     – Exposed to rate discounting based upon extended down-time.
