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.
51
Three Importance -Attitude and Behavior-
• Rich Concept.
• Flexible Action.
• Based on Principle.
• Say what you think.
• Ask what you don’t know.
• Apology your mistakes.
