Lessons Learnt from Logistic Industry
• Basic Service : ex. Collection of goods from location A
and deliver to location B
- Transport services
• Associated services : Convenience Store acts as a
mediator for collection. Deliveries be arranged in agreed
time and traceable.
- Operations Services
• Value added Services : Perishable goods ( fish, fruit) be
transported using a cold storage , delicate good be
transported using hanging
- Contents Aware Delivery Services

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.
