Question
Name the five usability objectives.
Answer
Learnability, efficiency, memorability, errors and satisfaction.
Question
Learnability vs memorability?
Answer
Learnability is the first use — can a newcomer finish unaided? Memorability is a return after weeks — can they still do it without relearning?
Question
What three things does the errors objective cover?
Answer
How many errors are made, how serious each one is, and how easily it can be recovered from.
Question
What turns a usability opinion into a usability evaluation?
Answer
A measurement taken the same way before and after: for example 6 of 20 first-time users completing the task unaided, rather than "it is hard to learn".
