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

Complete failure analyses on a minimum of three wheeled mobile plant steering and suspension systems with real or simulated multisystem and intermittent faults and identify evaluate select and document the most appropriate rectification measure

Analyse and validate or recommend variations to a minimum of two available repairmodification procedures for wheeled mobile plant steering and suspension systems

Document and report the diagnostic process and findings and recommended rectification for two of the above

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 material work instructions and deadlines

Access to a requirement and objectives for analysis and evaluation wheeled mobile plant steering and suspension systems with real or simulated faults monitoring processes and testing equipment appropriate to the objectives research facilities and technical information and a work environment

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 outcomeproduct 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

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