ITPEC IP October 2023 Question 47
ITPEC IP October 2023 — Question 47 of 100
Ease of learning, button layout, and text size and color all directly affect screen usability, so B, C, and D are correct. Users should be able to understand operations quickly, find and predict controls, and read content comfortably. Consistency, visibility, feedback, and accessibility reinforce these qualities.
Answer (d)
Why not others:
- A, time to recover from a system failure, is primarily a reliability, maintainability, or service-recovery measure rather than a screen-design usability property
- Choices (a), (b), and (c) all include A while omitting one genuine interface consideration
Key rule: Usable screen design focuses on learnability, understandable control placement, readability, consistency, feedback, and prevention or recovery from user errors.
