047 | Evaluative Research |
Testing of prototypes, products, or interfaces by users of a system in design development
- Evaluative research gauges human expectations against a designed artifact, determining whether something is useful, usable, and desirable.
- Testing should collect performance measures such as task speed and accuracy and preference measures such as aesthetic and emotional response.
- Research of existing and competing products may be useful in early stage design research, to inform new product development.
- Testing may be conducted in a lab setting or by people using products or prototypes in a real-world context.
- New crowdsourcing opportunities afford online testing by volunteers to assess how users are engaging with prototype interface designs and wireframes.
- Some forms of evaluation research such as cognitive walkthrough and heuristic evaluation use expert evaluators to assess products and interfaces.

Evaluation research can be formal or informal. In this example, evaluations were invited through a public display of prototypes for a proposed new signage program.
