User Experience Design Quality Control & Assurance 5 — Questions and Answers
Question 1: A UX team is preparing a design for release. They complete a 'design QA' pass by comparing the live implementation to Figma specs. What is this process commonly called?
- Guerrilla testing
- Design handoff review
- Pixel-perfect or design specification QA (Correct answer)
- Contextual inquiry
Correct answer: Pixel-perfect or design specification QA
Design specification QA (often called pixel-perfect review) compares the implemented product against design specs to catch deviations in spacing, typography, color, and component behavior.
Question 2: Which of the following is an example of 'false affordance' — a UX quality issue that QA should flag?
- A button that changes color when hovered
- An underlined text label that is not a clickable link (Correct answer)
- A search bar that shows recent queries on focus
- A disabled button that is grayed out
Correct answer: An underlined text label that is not a clickable link
An underlined non-link mimics a well-known affordance (hyperlinks) without functioning as one, misleading users about what is interactive.
Question 3: When conducting UX QA on an onboarding flow, a tester finds that skipping a step causes the app to crash. How should this defect be classified?
- Low severity — users are unlikely to skip steps
- Cosmetic — only affects some users
- Critical — causes app failure on a valid user action (Correct answer)
- Major — degrades experience but does not crash the app
Correct answer: Critical — causes app failure on a valid user action
Any defect that causes an application crash on a valid user action is classified as critical severity and must be resolved before release.
Question 4: A product manager requests a 'happiness metric' for ongoing quality monitoring. Which metric MOST directly captures user satisfaction over time?
- Task completion rate
- Customer Satisfaction Score (CSAT) or Net Promoter Score (NPS) (Correct answer)
- Page load time
- Number of support tickets opened
Correct answer: Customer Satisfaction Score (CSAT) or Net Promoter Score (NPS)
CSAT and NPS are industry-standard happiness metrics that directly survey users about their satisfaction and likelihood to recommend, tracking sentiment over time.
Question 5: What is the purpose of including 'happy path' AND 'unhappy path' test cases in UX QA?
- Happy path tests load performance; unhappy path tests accessibility
- Happy path validates the ideal user flow; unhappy path validates error handling and edge cases (Correct answer)
- Happy path is for novice users; unhappy path is for expert users
- Happy path tests mobile; unhappy path tests desktop
Correct answer: Happy path validates the ideal user flow; unhappy path validates error handling and edge cases
Happy path cases verify the intended optimal flow works, while unhappy path cases ensure the product handles errors, unexpected inputs, and edge cases gracefully.
Question 6: A UX quality audit reveals that modal dialogs on the site cannot be dismissed with the Escape key. Which WCAG success criterion does this most directly violate?
- 1.4.3 Contrast (Minimum)
- 2.1.2 No Keyboard Trap (Correct answer)
- 3.2.1 On Focus
- 4.1.2 Name, Role, Value
Correct answer: 2.1.2 No Keyboard Trap
WCAG 2.1.2 No Keyboard Trap requires that keyboard users can always navigate away from any component, including modals, using standard keys like Escape.
Question 7: A team uses the HEART framework (Google) to measure UX quality. Which dimension would track whether users return to the product regularly?
- Happiness
- Engagement
- Retention (Correct answer)
- Task Success
Correct answer: Retention
The Retention dimension of Google's HEART framework measures whether users return to the product over time, indicating sustained value and satisfaction.
