User testing
User testing is an evaluation method that observes or measures representative users interacting with a product or system while performing relevant tasks.
Design for Developers
User testing is the evaluation of a product or design by observing representative users perform tasks and collecting their responses.
- How it is used
- Validates designs and features by observing task use and turning feedback into iteration decisions.
- How deep it goes
- Explains task observation, prototype and live-site testing, interview prompts, notes, prioritization, and retesting without implementation internals.
- Examples
- Uses clickable wireframes, PowerPoint screen flows, telemetry-driven tool abandonment, and staging tests of replacement designs.
- What you can do after
- Apply it by preparing tasks, observing users, gathering feedback, prioritizing problems, and revising a design before release.
Architecture Modernization: Socio-technical alignment of software, strategy, and structure
Usability testing is a research method in which representative users evaluate a product or design while performing relevant tasks.
- How it is used
- Improves products by testing whether real users understand and value proposed designs.
- How deep it goes
- Explains repeated testing and design iteration, but does not detail test protocols, recruitment, or analysis procedures.
- Examples
- Uses energy performance certificate designs tested with real users as its central example.
- What you can do after
- Apply it via repeated testing to remove unhelpful content and prioritize information users consider important.
Lead Developer Career Guide
A technique that evaluates software by observing representative users interact with it.
- How it is used
- Uses direct observation of end users to assess prototype or early software usability and functionality.
- How deep it goes
- Defines the observation-based method and its purpose, but does not specify a testing procedure or analysis framework.
- Examples
- Uses prototype interaction and a B2B mismatch between technical client requests and nontechnical user needs.
- What you can do after
- Evaluate software usability and functionality through observed interaction with end users.
