  2. Users Define Quality. Overview: • What is usability testing? • How is it different from functional testing? • Why is it important? • Where do I start?

  3. Users Define Quality. Usability Testing is: • a means for measuring how well people can use some human-made object (such as a web page, a computer interface, a document, or a device) for its intended purpose

  4. Usability Testing: involves carefully creating a scenario, or realistic situation, where the person performs a list of tasks using the product being tested while observers watch and take notes. Functionality Testing: involves testing and evaluating that the entire application performs according to the system specification or requirements documentation. Users Define Quality.

  5. Users Define Quality. Why is usability important? • Competitive marketplace • Instant product service replacement often available • Difficult to recover lost reputation • High visibility, particularly in web-based applications • Negative media or review publications

  6. Users Define Quality. How do we evaluate usability? • Usable Design • Can I find what I am looking for? • Usable Functionality • Does it do what I expect it to?

  7. Users Define Quality. Usable Design: • Lay out • GUI • User flow • Ease of finding things

  8. Users Define Quality. Usable Functionality: • Error handling • Performs intended service • Expected use

  9. Users Define Quality. • Both usable design and usable functionality issues are cheaper to fix in the design phase • Reduces risk of customer visibility • Test should be revised and repeated after changes are made

  10. Process vs. Cost: Users Define Quality.

  11. Usability Labs: Audio recording Video recording Application navigation recording Eye-movement tracking Two-way mirrors Users Define Quality.

  12. Users Define Quality. PLAN: • Understand & identify your end users • What do you want to know? Identify goals • Develop your script • Develop pre and post test questionnaires

  13. Users Define Quality. Test Scripts should be: • Short. • Specific. • Realistic. • Simple.

  14. Users Define Quality. EXECUTE: Pre-test questionnaire One-on-one time Keep them talking! Ask “Why?” What to measure Accuracy Time on Task Recall Emotional Response Post-test questionnaire

  15. Users Define Quality. EVALUATE: • Compile tester demographics, test results, and feedback • Present your findings and recommendations • Based on risk/visibility • Do multiple iterations of test after changes are made
