Evaluation of ideas
- check design proposals against design specification;
- be able to consider modifying the specification in the light of design ideas and evaluation of them;
- review the design with the intention of reducing parts in order to simplify its construction or manufacture in quantity.
Development of ideas
Clarify the final design through decisions made through:
- modelling e.g. virtual, rapid prototype, modelling materials, constructional kits;
- client testing;
- consideration and selection materials
- consideration and selection of constructional details
- formal/CAD drawings.
Use simple tests to check the effectiveness of designs and evaluate against the specification criteria.
Planning for manufacture
- select and specify appropriate materials, quantities, sizes, tolerances;
- produce a sequence of instructions that would allow a competent third party or machine to manufacture the product;
- identify critical points for quality control, and time scales in the manufacturing process;
- develop methods to aid accuracy and repetition in manufacture.
Selection of appropriate processes and techniques for own product
Candidates should select and use the most appropriate technique(s) and process(es) to make their own product.
Evaluation of own product
Candidates should consider other people's views (client, designer, manufacturer, user/ consumer) when refining product designs; ensure that own product(s) are of suitable quality for intended users; test against original specification and against quality of similar commercial products.
Social, cultural, moral, environmental, sustainability, econonic issues
Candidates should identify the factors involved in consumer choice; carry out market research to establish consumer preferences of target market(s) and use this information to influence the design.
Consumer rights legislation, product maintenance and codes of practice
Candidates should take legal requirements concerning consumer rights and codes of practice relating to safety into account when designing products.
Sustainability and environmental issues
- understand the sustainability and environmental issues associated with the designing and making of products;
