UX Research Term

Usability Testing

Usability testing is a research method where real users interact with a product or interface while researchers observe and gather feedback. It helps teams identify problems, validate designs, and ensure products are easy and effective for their intended audience.

Why Usability Testing Matters

Usability testing is crucial because it:

  • Reveals actual user behavior (not just opinions)
  • Catches problems early when they're cheaper to fix
  • Provides evidence for design decisions
  • Reduces risk of launching unusable products
  • Helps teams build empathy with users

How Usability Testing Works

A typical usability test involves:

  1. Planning & Setup

    • Define test objectives
    • Create realistic tasks
    • Recruit representative participants
    • Prepare testing environment
  2. Test Session Components

    • Introduction and consent
    • Background questions
    • Task completion scenarios
    • Follow-up questions
    • Wrap-up discussion
  3. Data Collection Methods

    • Think-aloud protocols
    • Screen and audio recording
    • Observer notes
    • Task success metrics
    • Time-on-task measurements

Best Practices

Do:

  • Test with 5-7 users per round
  • Use clear, non-leading task instructions
  • Stay neutral during sessions
  • Take detailed notes
  • Record sessions (with permission)
  • Test throughout the design process

Don't:

  • Lead users to solutions
  • Skip the practice task
  • React to user struggles
  • Test everything at once
  • Forget to debrief participants

Common Mistakes to Avoid

  1. Testing Too Late Start testing early with prototypes, not just finished products

  2. Leading Questions Ask "What would you do next?" instead of "Would you click this button?"

  3. Wrong Participants Recruit users who match your target audience

  4. Too Many Tasks Focus on key scenarios rather than exhaustive testing

Connection to Card Sorting

Card sorting and usability testing work together in UX research:

  • Use card sorting to organize content
  • Follow up with usability testing to validate the resulting navigation
  • Combine methods for thorough information architecture validation

For example:

  1. Run a card sort to structure your website navigation
  2. Create a prototype based on results
  3. Conduct usability tests to verify the structure works

Types of Usability Testing

  1. Moderated Testing

    • Real-time observation
    • Direct interaction with participants
    • Rich qualitative feedback
  2. Unmoderated Testing

    • Remote participation
    • Larger sample sizes
    • Quantitative data focus
  3. Guerrilla Testing

    • Quick, informal sessions
    • Often in public spaces
    • Fast feedback on specific issues

Getting Started

Ready to run your first usability test? Here's a quick checklist:

  1. Define clear objectives
  2. Write 3-5 key tasks
  3. Recruit participants
  4. Prepare test environment
  5. Run a pilot test
  6. Conduct sessions
  7. Analyze results

Remember: Start small, focus on learning, and iterate based on what you discover. Even simple usability tests can provide valuable insights for improving your design.
