🎯 What you'll practice: Running a usability test that surfaces real friction points.
🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4
1Task-based testing gives participants:
2Think-aloud protocol asks participants to:
3According to the 5-user rule, testing ~5 users typically finds:
4"What would you do next?" is a good test question because it is:
🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11
5Testing 5 users, fixing issues, then testing 5 more is called an round.
6"Was that easy to find?" is an example of a question to avoid.
7Why does testing beyond ~5 users have diminishing returns?
8Rewrite this leading question neutrally: "Wasn't that button easy to find?"
9Why is testing 5 users, fixing, then testing 5 more better than testing 15 at once?
🚀 Section C · Challenge ● CHALLENGE 5
10Write a task-based test scenario (1 sentence) and 2 think-aloud prompts for testing a food-delivery app's checkout flow.

1-B 2-B 3-B 4-B | 5 = iterative 6 = leading 7 = Usability problems repeat heavily across users, so additional participants beyond ~5 mostly re-confirm issues already found 8 = e.g. "What did you notice about finding that button?" 9 = Because it lets the team fix found issues before the next round, so each round tests an improved version rather than the same flawed one repeatedly | 10 = Answers vary — e.g. Scenario: "Order a meal and complete checkout using a saved card." Prompts: "What are you looking at right now?" / "What do you expect to happen when you tap that?"
