Shneiderman's 5 Criteria for Measuring Usability

Time to learn: The time it takes to learn some basic level of skills
Speed of UI performance: Number of UI "interactions" it takes to accomplish tasks
Avoiding user errors: How often users make mistakes
Retention of skills: How well users remember how to use the UI after not using for a time
Subjective satisfaction: The lack of annoying features
