Learnability: How easy is it for users to accomplish basic tasks the first time they encounter the design?

Efficiency: Once users have learned the design, how quickly can they perform tasks?

Memorability: When users return to the design after a period of not using it how easily can they reestablish proficiency?

Errors: How many errors do users make, how severs are these errors and how easily can they recover from the errors?

Satisfaction: How pleasant is it to use the design?
