Elements and Performance Criteria
- Analyse network performance to determine service levels
- Establish network type and quality of service (QoS) standard levels required, in conjunction with equipment suppliers and customer opinion, to determine the benchmark for network performance standards
- Analyse trend analysis data and statistical data to assess level and type of network degradation
- Conduct performance tests according to established performance checklist to systematically evaluate QoS levels using appropriate performance analysis tools
- Analyse test results and determine QoS levels and network problems
- Establish restoration times in the event of service breakdown
- Determine, organise and allocate resources necessary to monitor service levels
- Monitor integrity of the network
- Manage delivery of quality service
- Conduct monitoring activities to maintain QoS levels and network integrity
- Analyse trouble reports and performance data including customer feedback on a regular basis as an indicator of network performance
- Analyse drive test data as an input to performance and optimise the network to improve network level of service
- Analyse problems and organise repair
- Analyse performance results regularly and initiate investigations when performance levels are below specified standards and recommend network changes
- Analyse causes of problems by testing specific network components
- Isolate problems where possible and escalate repair according to enterprise policy
- Undertake evaluation testing after repair to ensure the problem has been rectified
- Coordinate upgrade of software and hardware
- Develop strategies to affect changes according to recommendations and produce a plan to coordinate activities
- Produce a cost estimate of proposed change and submit a cost-benefit study for approval
- Confirm shortcomings in hardware and software and negotiate with planners for network modifications
- Evaluate modifications to ensure network compatibility and use of appropriate protocols providing QoS in the network
- Produce a plan for software and hardware changes to be initiated with minimum network downtime and customer impact
- Undertake tests following upgrade to ensure the level of performance planned as a result of the upgrade has been achieved
- Produce documentation including configuration details and tests results and submit to network planner
