Specific key competencies, underpinning and employability skills required to achieve the performance criteria
These include a number of processes that are learned throughout work and life, which are required in most jobs. Some of these are covered by the national key competencies, although others may be added. The details below highlight how these competencies are to be applied in the attainment of this unit.

Application of the key competencies in this unit are to satisfy the nominated level in which:

Level 1 - relates to working effectively within set conditions and processes;
Level 2 - relates to management or facilitation of conditions or processes; and
Level 3 - relates to design, development and evaluation of conditions or process
How will the candidate apply the following key competency in this unit? The candidate will need to:

Collect, analyse and organise information
Research, organise and understand technical information related to contemporary tracked, undercarriage and suspension systems, monitoring and testing processes, diagnostic methods and options and safety procedures
(Level 3)

Communicate ideas and information
Communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with site supervisor, other workers and customers, reporting of work outcomes and completion of regulatory, commercial and vehicle information systems inputs
(Level 2)

Plan and organise activities
Plan and organise activities, including the planning of analytical processes, establishment of evaluative (success) criteria, preparation and layout of the worksite and the obtaining of testing equipment and materials to avoid backtracking, workflow interruptions or wastage
(Level 2)

Work with others and in a team
Work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
(Level 2)

Use mathematical ideas and techniques
Use mathematical ideas and techniques to complete measurements, calculate analytical requirements, calibrate and establish testing equipment and present analytical results
(Level 2)

Solve problems
Establish analytical processes, including diagnostic processes, which anticipate and allow for risks, cater for both direct and indirect evidence, avoid or minimise reworking and avoid wastage
(Level 3)

Use technology
Use the workplace technology related to systems analysis and diagnosis, information research and management systems, testing equipment, maintenance equipment, tooling, calculators and measuring devices
(Level 2)

Context of assessment
Assessment may occur on the job or in a workplace simulated facility with process equipment, material, work instructions and deadlines

Method of assessment
Assessment of this unit of competence is most likely to be project related under real or simulated conditions and require portfolios or other forms of indirect evidence of process. Direct evidence may 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 circumstances

Specific resource requirements for this unit
Access to a requirement and objective(s) for analysis and evaluation, operational tracked mobile plant undercarriage and suspension systems with real or simulated faults, monitoring processes and testing equipment appropriate to the objective(s), research facilities and technical information and a work environment
