Front 20

Usability

Back 20

quality attribute that assesses how easy user interfaces are to use

Front 21

three measurements of usability

Back 21

effectiveness, efficiency, satisfaction

Front 22

effectiveness

Back 22

degree to which specific task could be accomplished by particular users working in a particular environment

Front 23

efficiency

Back 23

accuracy and completeness of goals in relation to effort expended

Front 24

Satisfaction

Back 24

comfort and acceptability of the system

Front 25

five quality components of usability

Back 25

Learnability, Efficiency, memorability, Errors, Satisfaction

Front 26

learnability

Back 26

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

Front 27

Efficiency

Back 27

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

Front 28

Memorability

Back 28

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

Front 29

errors

Back 29

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

Front 30

satisfaction

Back 30

How pleasant is it to use the design?

Schneiderman’s heuristics
(8 Golden Rules)

Back 34

1. Strive for consistency
2. Enable frequent users to use shortcuts
3. Offer informative feedback
4. Design dialogues to yield closure
5. Offer error prevention & simple error handling
6. Permit easy reversal of actions
7. Support internal locus of control
(Individual believes that his/her behaviour is guided by his/her personal
decisions and efforts. )
8. Reduce short-term memory load
