Apply these methods by collecting primary data from representative users, identifying recurring needs and difficulties, and converting findings into justified design requirements. In user-centred design, field research shows what users do, while interviews and focus groups help explain what users think, need, and value.
Applying each research method
| Method | How it is applied | Evidence produced |
|---|---|---|
| Field research | Observe users performing relevant tasks in their normal environment. Record actions, context, workarounds, errors, time constraints, and interactions with existing products. Avoid interfering unnecessarily. | Contextual observations, task notes, and measurements |
| Interviews | Ask individual users a planned mixture of open and closed questions. Use follow-up questions to explore their experiences, motivations, frustrations, and priorities. | Qualitative responses and comparable closed-question data |
| Focus groups | Moderate a structured discussion with several representative users. Present prompts, scenarios, or prototypes and ensure that all participants can contribute. | Agreements, disagreements, and reactions to ideas |
First, define the target user group and research objective. Select a representative sample and gain informed consent. Questions should be neutral rather than leading, and personal data should remain confidential.
Next, code findings into categories and frequency counts. Look for repeated patterns. Triangulation strengthens conclusions by comparing evidence from different methods. For example, users may claim in interviews that a handle is comfortable, while field observations reveal that they repeatedly change their grip.
User comments do not automatically become design specifications; interpret evidence as measurable requirements, such as: “The handle must accommodate the grip dimensions of the identified target-user range.”
