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.

• Based on Principle.
• Say what you think.
• Ask what you don’t know.
• Apology your mistakes.
