| 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. |
