Elements and Performance Criteria

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.
Maintenance repair and modification requirements
Maintenance repair and modification requirements may include:
scheduled maintenance required under the maintenance management system
unscheduled maintenance as a result of system/component failure
repairs to restore systems/components to operation
modifications to improve system/component reliability or maintainability
maintenance schedule change or equipment or component modification required because of a change in equipment performance requirements (e.g. changed production or product design)
competitive market pressure and ‘lean maintenance’
changes in available maintenance technology
resources supply (e.g. materials, labour and skills)
introduction or changes to asset technologies (e.g. mechanical, fluid, electrical, electronic and system control)
sustainability relevant to repair and modification design tasks
WHS, risk and applicable standards and code requirements

Planning processes
Planning processes may include:
establishing maintenance parameters and design criteria
contributing to the negotiation and advice process
preliminary planning, investigations and costing
identifying design, development, prototyping activities and skills requirements
planning and scheduling design activities
improving, adjusting and rescheduling as required by emergency contingencies and constraints

Design process
Where equipment or component repair or modification design is required the design process includes:
establish design parameters and criteria
research, measurement, experimentation and investigation
generating ideas
synthesis, problem solving and decision making, and addressing constraints
apply scientific principles, calculation and graphics, prototyping and mock-up techniques if required
selection of components and hardware
evaluating solutions against design criteria
consultation, adjustments and agreement
finalise design and sign-off

Design criteria
Design criteria may include:
function and fit for purpose
aesthetics
manufacturability and maintainability
sustainability
cost constraints
ergonomics and anthropometrics and physiology
facilities, plant, services and skills available
WHS and risk

Sustainability
Sustainability is used to mean the entire sustainable performance of the organisation/plant, including:
meeting all regulatory requirements
conforming to all industry covenants, protocols and best practice guides
minimising ecological and environmental footprint of process, plant and product
maximising economic benefit of process plant and product to the organisation and the community
minimising the negative WHS impact on employees, community and customer

Life cycle assessment
Life cycle analysis can be used to improve sustainability of repaired or modified equipment or components. It may be applied to all aspects of the repair or modification process

Appropriate licensed technical and professional assistance
Appropriate licensed technical and professional assistance may include:
technical support and advice relating to elements which have intrinsic dangers, such as:
high pressure
energised fluid vessels
high temperatures and heat energy capacity
wiring with high current control voltages above extra low voltage
professional support for technologies, such as:
specialist electric motor drives and controllers
specialist materials, plastics, metal alloys and nano materials
special processes, foundry, alloy welding, heat treatment, sealing and fastening

WHS, regulatory requirements and enterprise procedures

WHS, regulatory requirements and enterprise procedures may include:
WHS Acts and regulations
relevant standards
codes of practice from Australian and overseas engineering and technical associations and societies
risk assessments
registration requirements
safe work practices
state and territory regulatory requirements applying to electrical work

Standards and codes

Standards and codes refer to all relevant Australian and international standards and codes applicable to a particular maintenance repair and modification design task

Prototyping
Prototyping may include:
mock-ups, physical and virtual modelling with post-processing for computer numeric control (CNC) and rapid prototyping

Systems thinking
Systems thinking refers to the conduct of engineering work in a manner that demonstrates knowledge of how the interaction of different technical systems on equipment, machinery or structures, as well as the skills and techniques of personnel, combine to perform or support engineering-related operations, processes or projects. It embraces determining or establishing how the function of each technical system or component, as well as the skills and techniques of personnel, effects or potentially may effect, outcomes. Systems should be interpreted broadly within the context of the organisation and depending on the project or operation can include equipment, related facilities, material, software, internal services and personnel, and other organisations in the value chain

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 apply repair and modification techniques consistent with a design brief information, relevant standards and conventions.

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
communicate, negotiate and review maintenance brief with stakeholders
determine or confirm scientific principles and design techniques, WHS and regulatory requirements, and design specification requirements
evaluate multiple solutions
investigate life cycle design, sustainability, technical and professional assistance required, and maintenance alternatives for repairs and modifications
plan, schedule and coordinate the maintenance task
solve problems and make decisions with systems thinking for contingencies and constraints, and continuous improvement
define designs, specify and document and apply graphical techniques, modelling, mock-up or prototyping techniques
select components and hardware
create and maintain adequate and accurate calculations and design process records
report and document results and processes.

Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, then 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.

Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessment may be in conjunction with assessment of other units of competency where required.

Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
