graded A+ new!!
Section 1: Design Thinking Foundations and the
Iterative Process (Questions 1–15)
1. A design team is starting a new project to redesign a hospital patient check-
in system. Before proposing any solutions, what should be the team's FIRST
priority?
A. Sketching wireframes for the new interface
B. Building a high-fidelity prototype for stakeholder review
C. Conducting user research to understand patient frustrations and needs
D. Selecting the technology stack for the new system
Answer: C
Rationale: Design thinking begins with the Empathize stage, where the team
develops a deep understanding of users' experiences and pain points before defining
problems or generating solutions. Skipping directly to prototyping or technical
decisions risks solving the wrong problem -3-5 .
2. Which statement BEST describes the relationship between divergent and
convergent thinking in the design process?
A. Divergent thinking evaluates options; convergent thinking generates them
B. Divergent thinking expands possibilities; convergent thinking narrows and selects
C. Both are used exclusively during the Prototype stage
D. Divergent thinking is qualitative; convergent thinking is quantitative
Answer: B
Rationale: Divergent thinking produces a wide range of ideas without judgment,
while convergent thinking analyzes and selects the best options. The design process
alternates between these modes, typically diverging during ideation and converging
during synthesis and prioritization -3 .
3. A team has completed a round of usability testing and discovered several
usability issues. According to the iterative design process, what is the MOST
appropriate next step?
A. Release the product immediately and address issues in a future version
,B. Abandon the current concept and start over
C. Analyze the findings, prioritize the issues, refine the prototype, and test again
D. Conduct additional research to validate whether the issues are real
Answer: C
Rationale: Iteration involves a continuous loop of prototyping, testing, analyzing
feedback, refining, and retesting. The goal is to improve the design based on
evidence rather than discarding work or shipping known issues -2-6 .
4. Which of the following is the BEST example of a "wicked problem" that
design thinking is well-suited to address?
A. Calculating the optimal reorder point for inventory
B. Improving the experience of patients navigating a fragmented healthcare system
C. Determining the correct tax rate for a new product
D. Standardizing the color palette across a brand's website
Answer: B
Rationale: Wicked problems are complex, ambiguous, and have interdependent
variables with no single correct answer. Healthcare navigation involves multiple
stakeholders, emotional factors, and systemic issues—characteristics that suit design
thinking's iterative, human-centered approach -13 .
5. During the Ideate stage, a facilitator notices that team members are
critiquing ideas as they are generated. What should the facilitator do?
A. Allow the critique because it improves idea quality
B. Remind the team to defer judgment and encourage wild ideas
C. End the session and reschedule for a later time
D. Ask only the most senior team members to contribute ideas
Answer: B
Rationale: Effective brainstorming requires deferring judgment, encouraging wild
ideas, and building on others' contributions. Critiquing during ideation stifles
creativity and reduces the quantity and diversity of ideas generated -13 .
6. A product team argues that after four iteration cycles, the design is
"finished." What is the MOST professional response from a UX perspective?
A. "The iterative process should continue as long as user feedback identifies
meaningful improvements and resources allow"
B. "We must continue until the design achieves a 100% task success rate"
C. "Once we have tested with five users, the design is considered validated"
D. "Iteration should stop when the budget is exhausted, regardless of user feedback"
Answer: A
Rationale: Iteration is a continuous improvement cycle, and the appropriate
, stopping point balances user goals against project constraints. There is no fixed
number of iterations that guarantees completion; the decision should be evidence-
based and resource-aware -2 .
7. Which of the following BEST describes the purpose of a Point-of-View (POV)
statement in design thinking?
A. To summarize the project budget and timeline
B. To frame the problem from the user's perspective using the structure [User] needs
[Need] because [Insight]
C. To list all technical requirements for the development team
D. To document competitor features for benchmarking
Answer: B
Rationale: A POV statement synthesizes research insights into a concise, actionable
problem framing that keeps the team focused on user needs. It follows the structure
of user, need, and insight -13 .
8. What is the primary difference between a prototype and a final product?
A. Prototypes are always physical; final products are always digital
B. Prototypes are used for learning and testing assumptions; final products are
released to users
C. Prototypes must be high-fidelity; final products can be low-fidelity
D. There is no meaningful difference; the terms are interchangeable
Answer: B
Rationale: A prototype is an early, often low-fidelity representation used to explore
ideas and gather feedback. A final product is the outcome after multiple iterations
and validation. The purpose of a prototype is learning, not production -5 .
9. A team is deciding whether to use a low-fidelity or high-fidelity prototype
for an upcoming test. The primary goal is to explore several divergent layout
concepts quickly and cheaply. Which should they choose?
A. High-fidelity prototype, because it provides the most accurate user feedback
B. Low-fidelity prototype, because it allows rapid iteration and exploration without
significant investment
C. High-fidelity prototype, because stakeholders prefer polished visuals
D. Low-fidelity prototype, because users cannot provide meaningful feedback on
high-fidelity designs
Answer: B
Rationale: Low-fidelity prototypes such as paper sketches and basic wireframes are
ideal for early-stage exploration because they are fast, inexpensive, and encourage
honest feedback without the distraction of visual polish -8-13 .
