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 mechanical analysis techniques consistent with an analysis 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 analysis brief and specification requirements with stakeholders
• determine or confirm relevant scientific principles and analysis techniques, WHS and regulatory requirements
• evaluate multiple solutions
• investigate life cycle analysis and sustainability
• plan, schedule and coordinate the analysis task
• solve problems and make decisions with systems thinking for contingencies and constraints and continuous improvement
• define analysis, specify and document and apply graphical techniques, modelling, mock-up or prototyping techniques
• create and maintain adequate and accurate calculations and analysis 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 a simulated working environment 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.
• Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
• Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

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.

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.

Mechanical engineering analysis  

Mechanical engineering analysis may be required for a variety of reasons, including:

• design of mechanical devices and plant
• design or evaluation of significant modifications, process changes or improvements

• fitness for purpose evaluation
• installation and commissioning of plant and equipment

Planning processes 

Planning processes may include:

• establishing analysis parameters and criteria
• contributing to the negotiation and advice process

Analysis process 

Analysis as a systematic process includes:

• establish analysis 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

Analysis criteria 

Analysis includes relevant technical criteria and may also include criteria relating to:

• function
• manufacturability and maintainability
• marketability
• sustainability
• cost constraints
• ergonomics and anthropometrics and physiology
• facilities, plant and skills available
• contingencies and constraints minimisation
• safety 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 analysis 

Life cycle analysis can be used to improve sustainability of products and services. It may be applied to:

• all aspects of manufacture of a single product
• the entire operations of an organisation
• a particular aspect of operations, such as environmental implications

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
