 USABILITY |
| How efficiently and easily people can navigate an interface and use it as a source of information. The term usability also refers to methods for improving ease-of-use during the design process. Usability is defined by six quality components: |
| Qualities | Content |
|---|---|
| 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 re-establish proficiency. |
| Errors | How easily users can recover from the errors. |
| Satisfaction | How pleasant is it to use the design process. [1] |
