Mobile App Design Professional Standards & Competencies 4 — Questions and Answers
Question 1: A designer uses stock photography in a client app without checking the license. The photos require a commercial license. What professional failure occurred?
- Failure to follow brand guidelines
- Failure to verify intellectual property rights before use (Correct answer)
- Failure to compress image assets
- Failure to conduct A/B testing
Correct answer: Failure to verify intellectual property rights before use
Verifying that all assets have appropriate commercial licenses is a professional responsibility that prevents costly legal liability for the client.
Question 2: In agile mobile product teams, what is the designer's responsibility during a sprint retrospective?
- Presenting final designs to stakeholders
- Reflecting on process improvements and contributing feedback on design workflow (Correct answer)
- Completing all outstanding design tasks from the sprint
- Writing technical documentation for developers
Correct answer: Reflecting on process improvements and contributing feedback on design workflow
Retrospectives are team reflections on process; designers contribute feedback specifically about design workflow integration and collaboration.
Question 3: Which metric is a designer most professionally accountable for improving when tasked with reducing user drop-off during onboarding?
- Server response time
- Onboarding completion rate (Correct answer)
- Daily active users (DAU)
- App Store rating
Correct answer: Onboarding completion rate
Onboarding completion rate directly measures whether users successfully navigate the onboarding flow the designer is responsible for.
Question 4: A designer proposes a solution that works for 90% of users but excludes users with color blindness. What professional standard requires reconsideration?
- Brand consistency guidelines
- Inclusive design principles (Correct answer)
- App performance benchmarks
- Monetization strategy
Correct answer: Inclusive design principles
Inclusive design requires solutions that work for users across a range of abilities, including the approximately 8% of men with color vision deficiency.
Question 5: When transitioning app designs to a development team, what is the most critical professional deliverable a designer should provide?
- A marketing brief
- Annotated, developer-ready specs with interaction states and measurements (Correct answer)
- A retrospective report
- A competitive analysis
Correct answer: Annotated, developer-ready specs with interaction states and measurements
Annotated specs with measurements, states, and interaction notes enable developers to implement designs accurately without repeated designer clarification.
Question 6: What does a professional designer do when stakeholder opinions conflict with usability test findings?
- Always defer to the highest-ranking stakeholder
- Present data-backed findings and advocate for user-centered decisions (Correct answer)
- Abandon the user research and start over
- Implement both versions simultaneously
Correct answer: Present data-backed findings and advocate for user-centered decisions
Designers advocate for users by presenting usability evidence clearly, helping stakeholders make informed decisions rather than opinion-based ones.
Question 7: A freelance mobile designer works with three clients simultaneously. Which professional practice prevents conflict-of-interest issues?
- Keeping all client identities secret from each other
- Disclosing potential conflicts and avoiding work for direct competitors without consent (Correct answer)
- Charging different rates based on company size
- Limiting each client to 10 hours per week
Correct answer: Disclosing potential conflicts and avoiding work for direct competitors without consent
Disclosing potential conflicts and obtaining consent before working for competing clients is the professional standard for freelance ethics.
