5. Telecommunication Service Management Problem Overview
• Telecommunication services are increasingly complex, with the requirement to
converge the build and operations of heterogeneous technologies and IT systems
into composite services
• The customer experience is based across technologies, processes and traditional
organisational boundaries ie. VOIP, Mobile – broadband convergence
• One of the biggest challenge facing operators is in
o increasing efficiency and reducing cost of product delivery ( Capex )
o managing cost of ownership for systems and operations ( Opex )
• Budgets are restricted and are consumed by maintenance - increasing ROI on current
systems and resources and extending support staff efficiency is key

6. Assurance Problem Outline
Innovation curve
• Operator legacy landscape lags behind innovations in broadband, IP , device
development
• Organisational structure and processes are stovepipe focused within discrete
technology sectors , as per the legacy approach
Operational impacts
• Point solutions are developed to address new feature and service development
leading to proliferation of systems and increasing complexity in service delivery and
assurance operations
• Multiple teams working on the same issue ( Support Level 1 , 2 & 3 ) @Everyone is
working on the problem!
• Multiple tools and master data repositories lead to data inaccuracies , redundancies
and inconsistencies - pushing up operational costs

18. Part 3 – Methodology
The methods used to set up an assurance strategy
Page: 18
19. Approach
• Develop assurance process methodology based on eTOM, ITIL
• Develop management processes over service assurance cycle
• Source and select vendors and external service providers
• Establish organisational architecture blueprint
• Architecture definition for integration to external systems
• Pilot project definition and implementation
• Design and implementation management through architecture governance
Page: 19
20. Standards
• Define architecture standards to enable understanding the current environment and
planning for change – most of all consistency and traceability

23. Standards - Togaf
• Define technology architecture
to enable assurance process
throughout the system
landscape and ensure
consistency
• Security is key concern for
operational systems throughout
the organisation
Page: 23
24. Technology Definition
Using the TOGAF as a guideline , the target architecture will be defined according to the logical and physical
baseline components ,applicable to infrastructure modelling .
Technology Physical and logical views will be developed in conjunction with supporting documentation where
technology is deemed to be :
The set of systems,software and networks which enable , support and maintain the services delivered to the
organisations customers ,including but not restricted to the following areas :
• Desktop : Web browsers
• Infrastructure : Application,platform , data ,network , transmission
• Security : Application security
• Presentation : User Interface
• Application server :
• Management systems : Fault management , operational tools , support structure
• Data and storage :
Technology architecture is deemed to be :
The set of design principles for implementing the technology within an organisation , in fulfilling and enriching the
objectives laid out in the business architecture domain and providing the infrastructure and capability to
achieve the service delivery objectives .
Page: 24
25. Methodology : Classification and organisation
Defines the process of establishing a service based network management
strategy
• Apply standards to ensure common vocabulary and classification
terminology as well as alignment to current initiatives
• E-TOM and NGOSS provide process identification and mapping enabling visibility
and functional definition for acquisition and planning
o Service Fulfillment
o Service Assurance
• ITIL provides a service centric view of the functional landscape ( ITIL v3 ) ITSM
and BSA / BSM
• TOGAF provides architectural guidelines for strategic system decision making and
business alignment to technology
• Establish baseline reference for service infrastructure information
• Catalogue equipment
• Catalogue and classify services
• Identify organisational boundaries and ownership areas
• Develop process flow for each functional area ( Service impact assesment )
• Establish migration path
Page: 25
26. Methodology : Pilot Project
• Select a specific service with measurable SLA and bring under
configuration management
• Classification and service modelling
o Organisation
o Tools/Systems/Applications
o IT/Network/Engineering
• (Auto ) Discovery of network elements and systems
• Design Topology – system , network and circuit
• Implement in UCMDB
• Build change management process
• Build correlation rules
• Build Topology Based Event Correlation
