User Interview

Cómo ejecutarlo

1. 1

   Define your research question: What do you need to learn? (Not 'does this feature test well?' — that's validation. User interviews are for discovery.)

2. 2

   Recruit 5-8 participants from your target user group. 5 interviews reveal 85% of usability issues.

3. 3

   Write an interview guide: 5-8 open-ended questions, ordered from general to specific. Start with context (tell me about your day/work), not the product.

4. 4

   Conduct interviews in pairs when possible: one facilitator, one note-taker.

5. 5

   Ask 'why' multiple times. Dig behind the first answer — it's rarely the real one.

6. 6

   Never ask leading questions. Not: 'Do you find X frustrating?' Ask: 'Walk me through what happens when you try to do X.'

7. 7

   After each interview, capture key insights while fresh (within 1 hour).

8. 8

   After all interviews, use Affinity Mapping to cluster insights across participants.

Consejos

• Silence is your friend. After an answer, wait 3-5 seconds. The best insights often come after the pause.

• Ask about past behaviour, not hypothetical future behaviour. 'Tell me about the last time...' not 'Would you ever...'

• Never show your product in a discovery interview — it primes their answers.

• 5 interviews with the right people beat 50 survey responses from the wrong people.

Variaciones

Contextual Inquiry: observe users in their actual environment while they work (more insight than a meeting room). Guerrilla Research: 5-minute corridor interviews with whoever's available — lower quality but faster.
