Modify electronic systems

Assessment tool

Version 1.0
Issue Date: April 2024


This unit applies to modifications including approved design changes and/or replacement of components or sub-assemblies on electronic analog and digital systems.

Where drafting skills are required, then Unit MEM09003B (Prepare basic engineering drawing) or Unit MEM09004B (Perform electrical/electronic detail drafting) should be considered. Unit MEM05002B (Perform high reliability soldering and desoldering) must also be selected if soldering of components is required to advanced or military specifications, where the reliability of electrical connections is critical, or where surface mounted devices are being soldered/de-soldered.

Band: B

Unit Weight: 4

This unit covers undertaking modifications to electronic system(s) including the testing and evaluating the modified system.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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

A person who demonstrates competency in this unit must be able to modify electronic systems. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

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

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment

This unit may be assessed on the job, off the job or a combination of both. Where assessment occurs off the job, i.e. the candidate is not in productive work, an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with modifying electronic systems, or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Look for evidence that confirms skills in:

obtaining relevant instructions, schematics, circuit diagrams

obtaining relevant maintenance reports and system output information

recording proposed modifications

obtaining approval to for the proposed modifications

modifying electronic systems

amending relevant documents, circuit drawings, schematics etc.

checking modified electronic system for conformance to specification

programming computers including uploading/downloading of proprietary software

testing and evaluating modified electronic system

Required knowledge

Look for evidence that confirms knowledge of:

advanced analogue and digital electronics theory

system/computer protocols including communications, networks, intranet, SCADA etc.

modifications to be made to the electronic system

reasons for undertaking the modification

appropriate personnel to consult for technical advice

hazards associated with the electronic system including electro-static discharge (ESD)

probable causes for any detected trends and/or deviations from specification

appropriate authority to authorise modifications to electronic systems and changes to documentation, circuit drawings, schematics etc.

procedures to be followed when undertaking and recording modifications to electronic systems

tools and techniques to be used to modify the electronic system

procedures for amending documents, circuit drawings, schematics etc.

procedures for checking the performance of the modified electronic system

test equipment and techniques to be used to evaluate the modified electronic system

operational specifications to be achieved by the modified electronic system

deviations/variations of test results from operational specifications

probable causes of any deviations/variations from specification

likely effect of further modifications on electronic system performance

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, if used 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.

Modification

Approved design changes and /or replacement of components or sub-assemblies on electronic analog or digital systems

System

Interdependent equipment including computer, process, communication, digital, security/fire etc.

Test equipment

Continuity testers, ammeters, voltmeters, cathode ray oscilloscopes, frequency counters, signal generators, digital probes etc.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.

Observation Checklist

Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice Yes No Comments/feedback
Modification requirements are determined and understood by reference to schematics, circuit diagrams, documentation and/or consultation with appropriate authority. 
Where appropriate, maintenance reports and system output information is analysed to confirm the need and nature of modification. 
Scope and nature of modifications are determined, recorded to standard operating procedures and confirmed with appropriate authority. 
Modification/s are undertaken using correct and appropriate techniques, tools and procedures. 
Correct and appropriate amendments are undertaken to documentations, circuit drawing etc. using standard operating procedures. 
Modifications are checked/tested and evaluated for compliance with desired outcome or specification using correct and appropriate techniques, tools and test equipment. 
Additional modification changes, if required, are recommended using standard operating procedures.
