Elements and Performance Criteria

1. Prepare to design custom electronic installations
   • Work health and safety (WHS)/occupational health and safety (OHS) requirements and workplace procedures for relevant work area are identified, obtained and applied
2. Risk control measures are applied in accordance with workplace procedures prior to commencing work
3. Extent of the proposed custom electronic installation is determined from the design brief or in consultation with relevant person/s
4. Design development work is planned in consultation with others to meet scheduled timelines
5. Develop installation design
