Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria



1. Analyse network performance to determine service levels

1.1. Establish network type  and quality of service  (QoS ) standards levels required, in conjunction with equipment suppliers and customer  opinion, to determine the benchmark for network performance standards

1.2. Analyse trend analysis data and statistical data to assess the level and type of network degradation 

1.3. Conduct performance tests  according to established performance checklist  to systematically evaluate the level of QoS using appropriate performance analysis tools 

1.4. Analyse test results and determine the QoS levels and network problems

1.5. Establish restoration times in the event of service breakdown

1.6. Determine, organise and allocate resources necessary to monitor service levels

2. Monitor the integrity of the network

2.1. Monitor alarm panels and verify message retrieval system on an ongoing basis to maintain network integrity

2.2. Undertake real time analysis of data from all sources to determine network health

3. Manage the delivery of quality service

3.1. Conduct monitoring activities  to maintain the quality of service level and integrity of the network

3.2. Analyse trouble reports and performance data including customer feedback on a regular basis as an indicator of network performance

3.3. Analyse drive test data as an input to performance and optimise the network to improve network level of service

4. Analyse problems and organise repair

4.1. Analyse performance results regularly and initiate investigations when performance levels are below specified standards and recommend network changes

4.2. Analyse causes of problems by testing specific network components

4.3. Isolate problems where possible and escalate repair according to enterprise policy

4.4. Undertake evaluation testing after repair to ensure that the problem has been rectified

5. Coordinate upgrade of software and hardware

5.1. Develop strategies to affect changes according to recommendations and produce a plan to coordinate activities

5.2. Produce a cost estimate of proposed change and submit a cost-benefit study for approval

5.3. Confirm shortcomings in hardware and software and negotiate with planners for network modifications

5.4. Evaluate the modifications to ensure network compatibility and use of appropriate protocols providing QoS  in the network

5.5. Produce a plan for software and hardware changes to be initiated with minimum network downtime and customer impact

5.6. Undertake tests following upgrade to ensure the level of performance planned as a result of the upgrade has been achieved

5.7. Produce documentation including configuration details and tests results and submit to network planner

Evidence Guide


The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Evidence of the ability to:

  • interpret current network performance data
  • monitor the integrity of the network
  • manage the delivery of quality service
  • conduct performance tests using appropriate performance analysis tools
  • analyse problems and organise repair applying escalation procedures, if required, within service assurance guidelines
  • coordinate upgrade of software and hardware.

Context of and specific resources for assessment 

Assessment must ensure:

  • site where network performance analysis may be conducted
  • data from organisations involved in planning initiatives
  • range of software currently used in industry
  • relevant regulations, specifications that impact on service measures and forecasting activities.

Method of assessment 

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

  • review of proposed upgrade strategy prepared by the candidate, outlining cost-benefit analysis, equipment compatibility study and proposed testing routine
  • direct observation of the candidate undertaking a practical monitoring, testing or planning exercise
  • oral or written questioning to assess knowledge of monitoring and testing procedures and types of systems.

Guidance information for assessment 

Holistic assessment with other units relevant to the industry sector, workplaces and job role is recommended, for example:

  • ICTTEN6043A Undertake network traffic management
  • ICTTEN6045A Implement planned network changes with minimal impact to the customer
  • ICTTEN6047A Manage a common channel signalling network.

Aboriginal people and other people from a non-English speaking background may have second language issues.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.

In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.

Where applicable, physical resources should include equipment modified for people with special needs.
