  2. 2. Jan Moons Co-founder UXprobe Co-host UX Antwerp Certified Usability Designer @moonsjan +32 485 69 78 35
  3. 3. 1. What is usability?
  4. 4. Problem of unusable products Product team focuses on machine and underlying system. Not on the person who will actually use the system!
  5. 5. Different models User / Mental Model Representation a user has in his mind about the object he is interacting with Design / Conceptual Model Actual model that is given to the user through the design and interface of the product System Model How the system actually works
  6. 6. Good Design Model • Resembles User Model as close as possible • The more it resembles the more user friendly the product
  7. 7. ISO 9241-11 The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in specified context-of-use Bailey’s Human Performance Model
  8. 8. ISO 9241-11 – Measuring usability Effectiveness • Can users achieve their goals with the product? • Can they do what the product says it should be able to do? Efficiency How much effort is required from the users in order to achieve their goals? Satisfaction It is no good if users can achieve their goals quickly if they hate the system, they will probably go somewhere else
  9. 9. 2. What is usability testing?
  10. 10. Usability testing • Involves real users • Test participants perform real tasks to achieve their goals • Observe behavior: what test participants do and “say” • Observations are logged to analyze and identify real problems
  11. 11. Iterative process More rounds of small scale tests 1st round: most significant problems 1. Fix these problems… 2. 2nd round: new problems uncovered 3. Fix these problems… 4. Etc.
  12. 12. Small sample sizes ~5 participants in a usability test • Find about 80% of problems • 80% contains most important issues By the end of the design you might have tested with 20 – 30 participants if not more (with the assumption of 1 segment)!
  13. 13. 3. Conducting a usability test
  14. 14. Welcome participant Hey XXX, I am Jan and I have been asked by the team from Clear, a to- do app, to check how easy it is to use their app. I will give you some tasks which you should try to complete. In the meanwhile talk out loud and explain whatever you want to do, what you are looking for, how you feel, etc. Any Questions so far?
  15. 15. Audience observes! Take notes: • Behaviors: the first thing he does, unexpected behavior, etc. • Positive and negative comments • Errors / problems / issues • Completion (success or failure) on each task
  16. 16. Task 1 You are going for a swim tomorrow. To make sure you will not forget to pack the necessary “swimming gear”, you just downloaded the Clear app on your phone. You are going to make a new to-do list called: “Going for a swim” and add your “swimming gear” to it. Can you show us how you normally would do that? Tell me when you think you completed the task!
  17. 17. Task 1 Satisfaction Overall, how difficult or easy was the task to complete?
  18. 18. Task 2 You are ready to pack your Swimming gear You open up the Clear app again and start checking off the items you add to your rug sack. When you are done checking off your swimming gear, remove the to- do list all at once! Tell me when you think you completed the task!
  19. 19. Task 2 Satisfaction Overall, how difficult or easy was the task to complete?
  20. 20. End-of-session questions Would you recommend the Clear app to a friend? What did you like best about the Clear app? Anything you want to improve?
  21. 21. Thank participant
  22. 22. 4. Analyzing & reporting
  23. 23. What did we observe? • Behaviors • Positive and negative comments • Errors / problems / issues • Completion (success or failure) on each task
  24. 24. Zoek het energietarief voor gas en elektriciteit dat het beste bij jouw huidige situatie past S c e n a r i o 1 Task completion: 78% Time-on-Task: 6m35s Quotes Abandon • “Als dit niet werkt dan zoek ik wel op de website van de VREG zo ben ik ook bij mijn huidige leverancier terecht gekomen” • “Dat is vervelend! Als dit hun website is dan stop ik!” Satisfaction Hoe moeilijk of gemakkelijk was het om deze taak uit te voeren?
