WGU D652 Task 2 Design Applications Performance
Assessment Complete Digital Wireframe, Clickable
Low-Fidelity Prototype & Design Rationale 2026 Updated
This performance assessment evaluates competency in constructing a complete digital wireframe, a clickable
low-fidelity prototype, and a written design rationale aligned with user-centered design, information architecture,
and usability principles. It mirrors WGU D652 Task 2 expectations under the 2026 rubric. It contains 60
multiple-choice questions, each with four distractors and a fully worked rationale that explains why the keyed
answer is correct. Questions are organized into clearly labelled sections that mirror the major content areas of
the course. Targeted learning outcomes include: Produce a complete digital wireframe that applies information
architecture and layout hierarchy principles.; Build a clickable low-fidelity prototype demonstrating logical
interaction flow and navigation consistency.; Write a design rationale that justifies decisions using user-centered
design, usability heuristics, and accessibility standards.. Every item has been reviewed for clinical accuracy,
current guidelines, and clarity so that students can study with confidence and self-correct as they work through
the bank. Use it as a high-yield review immediately before the exam, or as a structured practice tool during the
unit - the rationales double as concise teaching notes. The recommended writing time is 3 hours, with a passing
score of Competent (rubric-based; equivalent to B or higher). Aligned with Aligned with WGU 2026 Performance
Assessment Rubric and US regional accreditation standards for design applications coursework. standards and

Section 1: General (Questions 1-60)
1 Which wireframe fidelity level best supports rapid IA validation before visual
design?
A) High-fidelity mockup with final typography and color
B) Low-fidelity grayscale wireframe with placeholder content
C) Interactive high-fidelity prototype with micro-animations
D) Pixel-perfect annotated redline specification
Answer: B
Rationale: Low-fidelity grayscale wireframes isolate structure and IA from visual
styling, enabling fast, low-cost iteration and stakeholder feedback on hierarchy and
flow. High-fidelity options introduce visual and interaction variables that confound
IA validation, and redlines are a handoff artifact, not a validation tool.
2 In a clickable low-fidelity prototype, which hotspot behavior best tests navigation
model comprehension?
A) Auto-advancing timed transitions between all screens
B) Static image with no interactive regions
C) Clickable regions mapped to plausible next screens per user intent
D) Hover-only tooltips describing each element
Answer: C
,Rationale: Mapping hotspots to plausible next screens lets evaluators test whether
users can predict and follow the navigation model, revealing IA and labeling issues.
Auto-advance removes user control, static images remove interactivity, and
hover-only tooltips test discoverability rather than navigation comprehension.
3 Which rationale statement best justifies placing primary navigation in a persistent
left rail?
A) It matches the competitor's layout and looks familiar
B) It reduces scanning cost for frequent tasks and supports global wayfinding
C) It allows more room for decorative hero imagery
D) It is the default component in the chosen design tool
Answer: B
Rationale: A persistent left rail lowers scanning cost for high-frequency tasks and
maintains global wayfinding by keeping navigation visible across screens.
Competitor mimicry, decorative space, and tool defaults are not user-centered
justifications and fail the 2026 rationale rubric.
4 Which heuristic violation occurs when a wireframe uses identical icons for 'Save'
and 'Submit'?
A) Match between system and real world
B) Recognition rather than recall
C) Consistency and standards
D) Error prevention
Answer: C
Rationale: Using identical icons for distinct actions violates consistency and
standards because visual signifiers no longer reliably map to functions, increasing
confusion. The other heuristics address terminology, memory load, and error
avoidance, not conflicting signifiers for different actions.
5 Which information architecture pattern best supports a product catalog with
multiple overlapping facets?
A) Strict hierarchical tree with single-parent categories
B) Sequential linear flow with back/next only
C) Faceted navigation with combinable filter dimensions
D) Alphabetical index with no cross-references
Answer: C
Rationale: Faceted navigation allows users to combine independent dimensions (e.g.,
price, size, brand), which suits overlapping attributes in catalogs. Hierarchical and
, sequential models force single paths, and alphabetical indexes lack the
cross-referencing needed for multi-attribute retrieval.
6 A wireframe's primary CTA is visually identical to secondary actions. Which
principle is most directly violated?
A) Fitts's Law
B) Visual hierarchy
C) Hick's Law
D) Jakob's Law
Answer: B
Rationale: Visual hierarchy uses contrast, size, and placement to signal importance;
making the primary CTA indistinguishable from secondary actions destroys that
signal. Fitts's Law concerns target acquisition time, Hick's Law concerns decision
time, and Jakob's Law concerns user expectations from prior experiences.
7 Which low-fidelity prototype artifact best documents conditional branching for
stakeholder review?
A) A single composite screenshot of the home page
B) A flowchart linking screens with labeled decision points
C) A style tile showing color and typography
D) A usability test script with no screen references
Answer: B
Rationale: A flowchart explicitly maps screens and decision points, making
conditional logic visible and reviewable. A composite screenshot, style tile, or test
script without screen references cannot communicate branching structure or decision
logic.
8 Which accessibility consideration should influence low-fidelity wireframe layout
decisions earliest?
A) Final brand color contrast ratios
B) Reading order and logical tab sequence
C) Micro-interaction easing curves
D) Retina image resolution specifications
Answer: B
Rationale: Reading order and tab sequence are structural concerns that must be
established in low-fidelity wireframes to support screen readers and keyboard users.
Color contrast, easing curves, and image resolution belong to later visual and
interaction design stages.
