Methods – Prototyping

method picture
What it is:

The creation of a physical representation or model of a finished design for evaluation by users. A prototype can range from a quick mock-up in craft materials to test an initial concept to a more highly resolved artefact closer to production. Prototyping makes abstract ideas real, communicates concepts clearly and helps to reduce the risk of costly mistakes in the later stages of development – useful lessons can be learned with each new prototype. Users have a more direct and less ambiguous interaction with a prototype compared to verbal or illustrative descriptions of an idea, which can be open to misinterpretation.

Background and further reading

The making of a prototype once fixed a product’s physical appearance and technical specification prior to manufacture. But in recent years the practice of rapid prototyping has moved this method from the back end of design development to support user research much earlier in the process. In the 1990s the design firm IDEO became a pioneer of building lots of quick, imperfect prototypes to test ideas on people. Today this practice has become engrained as the ability to make many and varied models makes it possible to involve users more closely and earlier during product development, involving people directly in the shaping process.
