Evidence Guide

EVIDENCE GUIDE 

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the 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 

  • Interpret work order and locate and apply information.
  • Apply safety requirements, including the isolation of equipment and use of personal protective equipment.
  • Follow work instructions, operating procedures and inspection processes to:
  • minimise the risk of injury to self and others
  • prevent damage and wastage of goods, equipment and products
  • maintain required production output and product quality.
  • Modify a significant electronic system or sub-system including:
  • external modification (not within the computer) to a digital computer management system enhancing the system performance
  • external modification (not within the computer) to a digital computer management system, utilising electronic circuit design, development, manufacture, trial, evaluation, improvement and commissioning, enhancing the system performance
  • internal modification (within the computer) to a digital computer management system, utilising electronic circuit design, reprogramming, development, manufacture, trial, evaluation, improvement, and commissioning enhancing the system performance.
  • Work effectively with others.
  • Modify activities to cater for variations in workplace context and environment.

Context of , and specific resources for assessment 

Assessment may occur on the job or in a workplace simulated facility with process equipment, materials, work instructions and deadlines.

Access to operational electronic systems requiring modification, testing equipment as stipulated in the Range Statement, technical information and a work environment.

Method of assessment 

Assessment of this unit of competence is most likely to be project related and require portfolios or other forms of indirect evidence of process. Direct evidence will include certification of compliance of the final outcome/product or authorisation for use by a competent authority.

Assessment must confirm the inference that competence is able not only to be satisfied under the particular circumstances, but is able to be transferred to other projects.

Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role.

Range Statement

RANGE STATEMENT 

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Electrical modifications 

Electronic modifications to be covered by this unit may include computer controlled systems where the process relates to three categories:

  • Modification carried out external to the computer, utilising 'off the shelf' components and modification to wiring circuitry.

Example :

  • Modification to an electronic engine management system, improving the performance of an ECU controlled engine cooling fan system necessitating changes to relay circuitry.
  • Modification carried out external to the computer, utilising electronic circuit design, development, manufacture, trial, evaluation, improvement, and commissioning.

Example :

  • Development of an electronic control unit to delay engine crank while sounding an alarm warning of impending start of hazardous equipment.
  • Modification carried out internally in the computer, utilising electronic circuit design, reprogramming, development, manufacture, trial, evaluation, improvement, and commissioning.

Examples are :

  • Rectification of an original internal computer design/operating deficiency
  • Modification to an electronic engine management computer, to enhance the performance of an engine
  • Modification to a computerised system, to disable a function no longer required by customer
  • Inputs to the modification method and processes may be obtained from customer requirements, manufacturer/component supplier specifications, outcomes of diagnostic processes or from regulatory, licensing, intellectual property legislation, safety requirements and Australian Design Rules

Unit context 

  • WHS requirements include legislation, vehicle industry regulations, safety management systems, hazardous substances and dangerous goods code and safe operating procedures.
  • Work is carried out in accordance with legislative obligations, Australian Design Rules, environmental legislation, health regulations, manual handling procedures and organisation insurance requirements.
  • Work requires individuals to demonstrate research, analytical, judgement and problem-solving skills in the diagnosis of faults.

Evaluation criteria 

Evaluation criteria, sometimes referred to as success factors, are to be established prior to a modification being undertaken and are to cover safety, functionality, survivability, maintainability life cycle cost and aesthetics.

Isolation procedures 

Equipment isolation procedures are to be to industry and enterprise standards.

Equipment 

Equipment is to include that appropriate to the modification being carried out, including electronic work station, desoldering station, electronic variable power supply, simulated vehicle system test facility, multimeters, lab oscilloscopes, logic probe and data scanners, and it should include computer-based diagnostic systems.

Personal protective equipment 

Personal protective equipment is to include that prescribed under legislation, regulations and enterprise policies and practices.

Information and procedures 

  • Workplace procedures relating to the use of tooling and equipment.
  • Workplace procedures relating to reporting and communication.
