ITPEC IP October 2018 Question 48
ITPEC IP October 2018 — Question 48 of 100
Ease of learning, pushbutton layout, and text size and color all affect screen usability. These correspond to B, C, and D. Recovery time after a system failure is an availability or maintainability concern rather than a screen-design characteristic.
Answer (d)
Why not others:
- every other option includes A, which does not describe the user interface of a screen
- options omitting B, C, or D exclude a genuine learnability, operability, or readability factor
Key rule: Usable screen design considers how easily users learn actions, locate controls, and perceive information; system recovery time is evaluated separately.
