Plan

Write a usability test script

Plan tasks for participants to attempt with the prototype.

How to do it

1. Write each task as a goal, not instructions.
2. Order tasks the way a real user would meet them.
3. Add a debrief question per task.

Tip. AI turns the prototype’s screens into tasks. Recruit people who match the persona.

What you need

Start from:

• Prototype

It is better with: Persona or Assumption map.

What you get: Interview script

An interview script template has these sections:

• Warm-up
• Core questions
• Wrap-up

Where it fits

• Deliver (Double Diamond): Test the chosen answer with real people and hand it over.

Usually comes after

• Build a prototype

What to do next

• Run usability tests
• Check for bias

Templates that use it

• Evaluative study: Does this design work for the people who will use it?
• Double Diamond: A whole project, from understanding a problem to a tested answer.
• Assumption-led (Lean UX): You already have an idea. What could sink it?
• Design Thinking: Empathize, define, ideate, prototype and test, in the classic five modes.
• Design Sprint: Five days from a big question to a prototype tested with real people.
