Usability is a quality attribute that assesses how easy user interfaces are to use. The word "usability" also refers to methods for improving ease-of-use during the design process.

Usability is defined by 5 quality components:

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

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

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

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

  • Satisfaction: How pleasant is it to use the design?

It's not you. Bad doors are everywhere.
