WGU C773 TASK 1 USER INTERFACE DESIGN
PARADIGM PET PROFESSIONALS FINAL
PAPER 2026 COMPLETE SOLUTIONS AND
CORRECT ANSWERS GRADED A+
⩥ Analysis, design, prototyping and evaluation. Answer: The three
phases of scenario-based design
⩥ activity, information design, and interaction design. Answer: The three
types of scenarios used in the design phase of scenario-based design
⩥ goal, attribute, criteria to measure attainment, targeted users,
preconditions. Answer: Components of a usability specification
⩥ Plan and prepare, test, collect data, analyze, draw conclusions,
document, redesign. Answer: The steps of the usability testing procedure
⩥ formative testing. Answer: Term for testing done during product
design, used to assess the usability of the in-progress product and the
effectiveness of the current design direction
⩥ summative testing. Answer: Term for testing done after product is
finished, used to assess the usability of the final product and see how
well it compares to similar products
, ⩥ structure principle. Answer: This states that design should organize
the user interface into a form that is clearly understandable for the user
⩥ simplicity principle. Answer: This states that design should make
common tasks easy to perform and that it should communicate clearly in
the user's native language
⩥ visibility principle. Answer: This states that design should make all
the necessary tools and options for a task clearly visible to the user, and
should not burden the user with superfluous information
⩥ feedback principle. Answer: This states that design should keep the
user informed of errors and changes of state
⩥ tolerance principle. Answer: This states that design should be flexible
and forgiving, should minimize the occurrence of user errors, and reduce
the consequence of the errors via undo/redo
⩥ reuse principle. Answer: This states that design should reuse objects
and behaviors to maintain consistency, and to minimize the need for
users to rely on thought and memory
⩥ contrast, alignment, repetition, proximity. Answer: What does CARP
stand for?
