Elements and Performance Criteria

ELEMENT 

PERFORMANCE CRITERIA 

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Prepare for fault- finding activity

1.1 Obtain approval for site access from customer or site owner prior to site entry

1.2 Identify existing and potential site hazards, assess risks and implement risk control measures

1.3 Determine, from documentation or discussion with appropriate personnel, work to be undertaken, including reported fault location

1.4 Prepare testing in consultation with others affected by proposed work and sequence work according to established enterprise procedures

1.5 Obtain required materials for testing, reporting and rectification work according to established enterprise procedures and job/work ticket requirements

1.6 Obtain required tools, equipment and testing devices according to enterprise procedures and check for correct operation and safety

2. Conduct network fault-finding activities

2.1 Establish nature of fault through analysis of source and available information

2.2 Select and safely use appropriate test equipment to locate, diagnose and analyse fault

2.3 Conduct tests according to test equipment operating instructions and requirements, and ensure diagnostic process does not compromise integrity of network element or system

2.4 Identify and test for faults efficiently without damage to equipment, circuits, surrounding environment or services

2.5 Evaluate test results to determine cause of fault/s using appropriate methods and processes

3 Action identified fault/s

3.1 Rectify faults or escalate to appropriate personnel according to test results and enterprise procedures

3.2 Confirm that fault rectification meets network performance requirements/levels

3.3 Use escalation process for dealing with unexpected situations according to enterprise procedures

4. Report fault-findings and rectification

4.1 Close out fault and update records using applicable work management systems

4.2 Restore worksite according to enterprise procedures

4.3 Notify appropriate personnel when work has been completed and obtain sign-off

Foundation Skills
