Design
- Briefs, research & evaluationTo inform the product design specification.
- SpecificationsA list of everything the product must do, be and have. It sets clear boundaries for the designer…
- Idea generation & developmentGenerating a range of original ideas is hard. Techniques give a starting point, help overcome…
- ModellingModels are used through the whole design process to:
