Elements and Performance Criteria

1. Prepare to design and develop digital system
   • Work health and safety (WHS)/occupational health and safety (OHS) requirements and workplace processes and procedures for a given design work area are identified and applied
2. WHS/OHS risk control measures and workplace procedures are followed in preparation for the design work
3. Extent of the proposed digital system development is determined from the design brief or in consultation with appropriate person/s
4. Design development work is planned to meet scheduled timelines in consultation with other person/s involved in the development work
5. Materials and devices/components required for the development work are selected on compatibility of their specifications with digital system requirements and project budget constraints
6. Tools, equipment and testing devices needed to carry out the development work are obtained and checked for correct operation and safety
7. Design and develop advanced digital system
   • WHS/OHS risk control work measures and workplace procedures are followed
8. Digital devices and system and compliance industry standards are applied to the digital system design
9. Alternative arrangements for the design are considered based on the requirements outlined in the design brief
10. Safety, functional and budget considerations are incorporated in the design
11. Prototype devices and circuits are constructed and tested for compliance with the design brief, industry standards and regulatory requirements
12. Prototype malfunctions are rectified and retested to ensure effective operation of design
13. Digital system design is documented for submission to appropriate person/s for approval
14. Unplanned situations are responded to in accordance with workplace procedures in a manner that minimises risk to personnel and equipment
15. Obtain approval for the design
    • Design is presented and explained to client representative and/or relevant person/s
16. Requests for modifications to the design are negotiated with relevant person/s within the constraints of workplace policy
17. Final design is documented and approval obtained from appropriate person/s
18. Quality of work is monitored against design brief performance agreement and/or workplace procedures or industry standards
