A look into usability design at Google (Google Cloud Next '17)

Usability is a quality attribute that assesses how easy user interfaces are to use.

Learnability - How easy is the first-time experience.
Efficiency - How few keystrokes (or clicks / or whatever metric makes sense) are required to get the job done for repeat users.
Memorability - How easy is to get started after you come back to the product after a while.
Accessibility - Not just for people with disabilities. Think of how easy it is to use when outside under sunlight, or if user breaks their hand.
