Usability

Usability

Usability is a measure of the quality of a person's experience in interacting with content or services.

Initially a discipline focused on computer software development, usability also relates to website design and is evaluated in terms of:

  • Ease of learning
    How fast can a user who has never seen the user interface before learn it sufficiently well to accomplish basic tasks?
  • Efficiency of use
    Once an experienced user has learned to use the system, how fast can he or she accomplish tasks?
  • Memorability
    If a user has used the system before, can he or she remember enough to use it effectively the next time or does the user have to start over again learning everything?
  • Error frequency and severity
    How often do users make errors while using the system, how serious are these errors, and how do users recover from these errors?
  • Subjective satisfaction
    How much does the user like using the system?
