  • 1. Web Usability UCR Webmasters Support Group Michael Yonezawa September 9th, 2004
  • 2. What is Usability?
    • Usability is the measure of the quality of a user's experience when interacting with a product or system — whether a Web site, a software application, mobile technology, or any user-operated device.
    • http:// www.usability.gov
  • 3. What is Usability?
    • Usability is a combination of factors that affect the user's experience with the product or system, including:
      • Ease of learning
      • Efficiency of use
      • Memorability
      • Error frequency and severity
      • Subjective satisfaction
  • 4. Ease of learning
    • How fast can a user who has never seen the user interface before learn it sufficiently well to accomplish basic tasks?
  • 5. Efficiency of use
    • Once an experienced user has learned to use the system, how fast can he or she accomplish tasks?
  • 6. 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?
  • 7. 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?
  • 8. Subjective satisfaction
    • How much does the user like using the system?
