DTA2.2 — Prototyping techniques

Design Technology · SL / HL · syllabus-mapped notes

1. DTA2.2.1

   Low and high fidelity

   There are two techniques used in iterative design and development: low fidelity and high fidelity.

2. DTA2.2.2

   Drawings, manual and CAD

   Drawings, either manual or prepared using computer-aided design (CAD) software, are used to explore, refine and communicate ideas.

3. DTA2.2.3

   Physical and virtual prototypes

   Prototypes can be developed in both physical and virtual (digital) form.

4. DTA2.2.4

   Physical prototypes

   Physical prototypes are used to test ideas and gather insights that inform the development of a product.

5. DTA2.2.5

   Virtual prototypes with CAD

   CAD is used to create virtual prototypes to test ideas and gather insights that inform the development of a product.

6. DTA2.2.6

   Rapid prototyping

   Rapid prototyping is used to create physical prototypes quickly for potential users and design teams to interact with them and provide feedback to drive design development forward.
