User Experience Design Case Studies & Practical Application 5 — Questions and Answers
Question 1: A UX team is asked to evaluate a competitor's app without access to their user data. Which method is MOST appropriate?
- Recruiting the competitor's users for interviews
- Conducting a heuristic evaluation against established usability principles (Correct answer)
- Reviewing the competitor's source code
- Running a technical performance audit
Correct answer: Conducting a heuristic evaluation against established usability principles
Heuristic evaluation allows experts to assess a product against recognized usability principles without requiring access to proprietary data or the competitor's users.
Question 2: In a diary study of remote workers using a project management tool, participants report the app is 'fine' but rarely return to it. What does this gap signal?
- The diary study methodology is flawed
- The tool satisfies hygiene needs but fails to deliver compelling value that builds habit (Correct answer)
- Users are too busy to use any tool consistently
- The app needs a dark mode
Correct answer: The tool satisfies hygiene needs but fails to deliver compelling value that builds habit
Neutral sentiment paired with low return visits indicates the app avoids major pain but lacks the value hooks or habit-forming loops that drive sustained engagement.
Question 3: A ride-sharing app displays surge pricing with a 2.1x multiplier. User complaints spike. Redesigning to show the estimated total fare (not the multiplier) reduces complaints by 55%. What principle explains this?
- Hick's Law
- Anchoring and framing effects (Correct answer)
- The serial position effect
- Von Restorff effect
Correct answer: Anchoring and framing effects
Framing the same information as a concrete dollar amount rather than a multiplier reduces psychological reactance because users evaluate absolute cost more comfortably than abstract ratios.
Question 4: A UX researcher wants to understand why users abandon a form without submitting. Which combination of tools provides the richest insight?
- Only Google Analytics pageviews
- Funnel analytics to find drop-off points + session recordings to observe behavior + micro-surveys at exit (Correct answer)
- Social media sentiment analysis
- A/B test of two form versions only
Correct answer: Funnel analytics to find drop-off points + session recordings to observe behavior + micro-surveys at exit
Funnel analytics identify where drop-off occurs, session recordings show how it happens behaviorally, and exit micro-surveys capture why—together covering quantitative and qualitative dimensions.
Question 5: A design system is introduced across a large organization. Six months later, product teams have created dozens of component variants that deviate from the system. What does this indicate?
- The design system is unnecessary and should be removed
- The system lacks flexibility or doesn't address real product needs, driving teams to work around it (Correct answer)
- Design systems always become fragmented over time
- Engineers are not following documentation
Correct answer: The system lacks flexibility or doesn't address real product needs, driving teams to work around it
Widespread workarounds signal the design system isn't meeting teams' legitimate needs; the system must evolve to accommodate edge cases or offer more flexible primitives.
Question 6: A case study shows that adding a 'Save for Later' option to an e-commerce cart reduced cart abandonment by 18%. Which UX insight does this demonstrate?
- Users don't want to buy products online
- Providing low-commitment paths acknowledges users' decision-making stage and reduces abandonment pressure (Correct answer)
- Cart abandonment is caused solely by price
- Users prefer wishlists to carts
Correct answer: Providing low-commitment paths acknowledges users' decision-making stage and reduces abandonment pressure
Not all users are ready to buy; offering a low-commitment save option meets users where they are in the decision journey, reducing the pressure that causes abandonment.
Question 7: A healthcare portal redesign improved aesthetics and speed, but accessibility testing reveals screen reader users can't complete key tasks. What is the correct prioritization?
- Ship the redesign and address accessibility in a future sprint
- Block the launch until accessibility issues blocking core tasks are resolved (Correct answer)
- Provide a separate 'accessible version' of the portal
- Notify screen reader users by email about the limitations
Correct answer: Block the launch until accessibility issues blocking core tasks are resolved
In healthcare contexts, inaccessible core tasks are a legal liability (ADA/Section 508) and a patient safety issue—blocking launch is the only ethical and compliant choice.
