Utility | A key attribute of a design process is utility, which refers to the design's functionality. Usability and utility are equally important. |
Learnability | An easy way for users to accomplish basic tasks the first time they encounter the design (a user-friendly Website). |
Efficiency | Once users have learned the design, how quickly can they perform tasks. |
Memorability | When users return to the design after a period of time, how easily can they reestablish proficiency. |
Errors | How easily users can recover from the errors. |
Satisfaction | How pleasant is it to use the design process. |
