Usability
Learnability: How fast the user can learn and perform basic tasks on the interface that they have never used before.
Efficiency: After learning how to use and complete basic tasks on the interface,
this is about how fast they can now do the tasks.
Memorability: Should the user be away from the interface for a period of time, can he or she still come back and know how to use it effectively.
Error Management: makes it easy for the user to recover from a unforced error (ex: clicking on something he or she didn't mean to), reduce the amount of errors on the interface to avoid and reducing the severity of them.
Satisfaction: How pleasant the users experience has been, how much they liked it and what they liked.
