  3. Efficiency (task completion time)
  4. Reliability (minimizes errors, some may call this effectiveness)
  5. Satisfaction
  6. Accessibility

Discussion Questions

  • How might learnability be defined?
  • How might efficiency be defined?
  • How do you choose and refine evaluation objectives for the evaluation of your design?
  • Can a usability test evaluate utility?
