required in most jobs. Some of these are covered by the national key competencies, although 
others may be added. The questions below highlight how these processes are applied in this 
competency unit. The number in brackets indicates the level to which the key competency 
needs to be demonstrated where (1) is where work is within set conditions and process, (2) is 
where the management or facilitation of conditions or process is exercised, and (3) is where 
the design and/or development of conditions or process are required.

EVIDENCE GUIDE 

Resource implications 

• 

Access to operational mechanical system(s), information 
on the required or proposed modification, testing 
equipment for the work and a realistic work environment 

Method of assessment 

• 

Assessment of this competency is most likely to be 
project related and require portfolios or other forms of 
indirect evidence of process.  Direct evidence will include 
certification of compliance of the final outcome/product 
or authorisation for use by a competent authority 

• 

Assessment must confirm the inference that competency 
is able not only to be satisfied under the particular 
circumstances, but is able to be transferred to other 
projects 

Context/s of assessment 

• 

Assessment may occur on the job or in a workplace 
simulated facility with relevant process equipment, 
material and deadlines
