Elements and Performance Criteria

1. Clarify product, process, system or service design requirements
   • Discuss and clarify design specification of the required product, process, system or service is discussed with the client and design team
2. Apply graphical techniques to produce the initial product, process, system or service design representation
   • Confirm initial graphical representation satisfies the design specification, manufacturing and operational requirements, safety and related standards
   • Perform engineering calculations using engineering references, standards and codes appropriately to determine dimensions, limits and fits, surface textures, datum references and geometric tolerances
   • Identify materials, manufacturing methods and processes of initial design representation
   • Prepare initial production graphics, specifications and operating and maintenance instructions/manuals in accordance with the agreed design concept and organisational requirements using chosen graphical techniques
3. Validate the product, process, system or service representation
   • Confirm suitability of the product, process, system or service design graphical representation with the client, other team members and organisational requirements
4. Develop, validate, implement and file design graphics and specifications and procedural documentation
   • Prepare design graphics, specifications and instructions for the product, process, system or service in accordance with the agreed design concept and organisational requirements and incorporate feedback on initial design graphics and documents
   • Check production graphics, specifications and instructions for the product, process, system or service with the client, design team and other affected persons for suitability prior to implementation
   • Respond to implementation installation and commissioning feedback in accordance with organisational requirements
   • Maintain validated production graphics, specifications instructions for the product process, system or service are throughout the implementation, installation and commissioning processes, and process and file in accordance with organisational requirements

Required Skills

Required knowledge includes the procedures for collaborating with the client and other staff in the selection of the preferred option significance of graphical representations of designs in terms of procedural requirements design objectives and client or contractual requirements relevant manufacturing and operational requirements safety and related standards the functional operation of the componentassembly to be drawn surfaces that are to be in contact or separated the appropriate type of fit for contacting surfaces the reasons for selecting the chosen type of fit the effect of surface finish on the performanceoperation of surfaces appropriate datum points procedures for determining tolerances design functional specification choice of components materials methods and processes in terms of the range of options available and the manner in which the design specification is satisfied options for graphical methods of representation scientific principles and mathematical techniques underpinning design element choices and decisions required graphical representation procedures for the preparation of production drawings specifications and operating and maintenance instructionsmanuals clients and other people affected by the design organisational procedures and required communication techniques organisational requirements for the preparation of production drawings specifications and operating and maintenance instructionsmanuals for products and systems persons to be consulted and procedures for verifying and implementing production graphics technical specifications and operational and maintenance instructionsmanuals worksite procedures for acting on implementation installation and commissioning feedback worksite procedures for the processing and filing of production graphics specifications and operating and maintenance instructionsmanuals file storage and archiving procedures Required skills include using appropriate communication skills for contacting and confirming specifications with the client discussing the alternative options and their relative strengths and weaknesses with the client and selecting the most acceptable option chosen applying graphical techniques correctly addressing design specifications manufacturing and operational requirements safety and related standards appropriately in the initial graphical representations presenting the graphical representations the dimensions limits and fits tolerances and surface textures datum references and geometry tolerances as determined by design calculations and in accordance with engineering references standards and codes producing initial graphical representation and documentation materials manufacturing methods and processes and design functional specification sufficient for client design team and interested party consultation and validation producing initial graphical representations to organisational requirements using suitable graphical techniques producing initial production graphics technical specifications and operational and maintenance instructionsmanuals in accordance with worksite procedures and client needs using appropriate communication skills in confirming that the design graphical representation meets the needs of the client and the expectations of other team members and interested parties completing organisational procedures and signoff documentation preparing production graphics specifications and instructions in accordance with the agreed design concept and organisational requirements and incorporating feedback on initial design graphics contacting the client design team and other affected persons and the production graphics technical specifications and verifying operational and maintenance instructionsmanuals prior to implementation incorporating feedback from the implementation installation and commissioning phases into final graphics specifications processing filing and saving all graphics specifications instructions and related documentation in correct format and location in accordance with worksite procedures

Evidence Required

Overview of assessment	A person who demonstrates competency in this unit must be able to represent the design of avionic engineering products processes systems or services for a range of engineering applications Competency in this unit cannot be claimed until all prerequisites have been satisfied
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency
Context of and specific resources for assessment	This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job that is the candidate is not in productive work then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team The assessment environment should not disadvantage the candidate The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials
Method of assessment	This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with represent the design of avionic engineering products processes systems or services or other units requiring the exercise of the skills and knowledge covered by this unit
