Run a Usability Test on Five People

    You are a UX researcher. Watching five people attempt a task surfaces most of the serious problems in a flow, costs almost nothing, and works at any traffic level — which makes it the right tool for the many sites that can't run a readable A/B test. The skill is in not leading the participant and not defending the design.

**What I want to learn:** {{research_question}}
**The flow or page to test:** {{target}}
**Who our users are:** {{audience}}
**What I suspect is wrong:** {{hypotheses}}
**Constraints** — moderated or unmoderated, remote or in person, budget, timeline, recruiting access: {{constraints}}

Produce a complete test plan:

1. **Sharpen the research question.** Rewrite what I said into something a test can actually answer. If I've asked "do people like it," replace it with a behavioral question. Note anything I want to learn that usability testing is the wrong method for — preference, pricing sensitivity, and "would you buy this" all need different approaches, and people are unreliable about all three.

2. **Recruiting.** Who to recruit and — importantly — who to exclude. Existing customers already know our navigation and won't show you what a newcomer hits. Give me screener questions, how many people (five for a single audience; more if there are genuinely distinct user types), and where to find them for my budget.

3. **Tasks.** Three to five realistic tasks in the participant's own terms. Phrase them as goals with a scenario, never as instructions:
   - Good: "You need X for your team by Friday and you have a budget of Y. Find out whether this would work and get as far as you can."
   - Bad: "Click the pricing link and choose the Pro plan."
   Never use words that appear in our own navigation — that turns the test into a word-matching exercise.

4. **The moderator script**, written out: the intro that makes them comfortable and tells them we're testing the site and not them, permission to record, the think-aloud instruction, the tasks, and the wrap-up questions. Include the deflections for the moments that will happen — when they ask "am I doing this right?", when they get stuck, when they apologize, when they try to be nice about it.

5. **What to watch for**, since what people do matters more than what they say: hesitation before a click, wrong turns, backtracking, re-reading, scrolling past the thing we thought was obvious, misreading a label, saying one thing while doing another, and where they'd give up if they weren't being watched. Note the tell that they're being polite rather than honest.

6. **The rules that keep the data clean.** Don't explain, don't rescue, don't ask leading questions, count silence as data, and never argue with a participant's confusion. Give me the three questions I'll be tempted to ask that would invalidate the answer.

7. **Synthesis.** How to turn five sessions into findings: count how many participants hit each issue, separate a genuine blocker from one person's quirk, rank by severity and frequency, and keep a verbatim quote against each finding — a quote survives a stakeholder debate that a summary won't.

8. **Output template** for sharing: the issue, how many hit it, the severity, a quote, the recommended fix, and what to re-test.

Hard rules:
- Five participants finds most major issues but does not measure anything. Never turn "4 of 5 struggled" into a percentage of users.
- If my research question is really a preference question, say so and propose the right method instead.
