Mobile App Design User Experience (UX) Fundamentals 2 — Questions and Answers
Question 1: What is the 'double diamond' design process model?
- A method for A/B testing two design variations simultaneously
- A four-phase framework: Discover, Define, Develop, Deliver (Correct answer)
- A technique for creating diamond-shaped UI layouts
- A two-sprint agile framework for UX teams
Correct answer: A four-phase framework: Discover, Define, Develop, Deliver
The Double Diamond model divides design into two phases of divergent then convergent thinking: first defining the right problem, then creating the right solution.
Question 2: In mobile UX, what does 'information architecture (IA)' primarily define?
- The technical data storage structure
- How content and features are organized, labeled, and navigated within an app (Correct answer)
- The app's API design
- The visual styling of menus
Correct answer: How content and features are organized, labeled, and navigated within an app
Information architecture structures and organizes content so users can find what they need efficiently and intuitively.
Question 3: What is 'card sorting' used to determine in mobile app design?
- The priority order of development tasks
- How users mentally categorize and group content or features (Correct answer)
- The visual layout of card-based UI components
- App performance benchmarking
Correct answer: How users mentally categorize and group content or features
Card sorting reveals users' mental models for organizing information, helping designers create intuitive navigation and categorization.
Question 4: Which UX concept describes the total effort a user expends to learn and use an interface?
- Cognitive load
- Interaction cost (Correct answer)
- Mental model
- Learnability
Correct answer: Interaction cost
Interaction cost is the total physical and mental effort users must invest to complete a goal — good UX minimizes this cost.
Question 5: What is a 'mental model' in the context of mobile UX design?
- A psychological test administered to users
- A user's internal understanding of how a system works based on prior experience (Correct answer)
- A design framework for mental health apps
- A model used to simulate user behavior with AI
Correct answer: A user's internal understanding of how a system works based on prior experience
A mental model is the user's existing belief about how something works, which designers must align with to create intuitive interfaces.
Question 6: Which principle advises that mobile apps should match users' real-world concepts and speak their language?
- Consistency and standards
- Match between system and the real world (Correct answer)
- Error prevention
- Aesthetic and minimalist design
Correct answer: Match between system and the real world
Nielsen's heuristic 'Match between system and the real world' states that interfaces should use words and concepts familiar to users.
