  2. 2. Outline<br />What is Usability Testing?<br />When is it most beneficial?<br />Who can be involved?<br />Who can it be most beneficial to?<br />How is it accomplished?<br />Format<br />Cost Factors<br />
  3. 3. What is Usability Testing?<br />Observing an end-user perform scenario-based tasks<br />Participants will typically be asked to follow the “think-aloud protocol” which asks the participant to say whatever they are looking at, thinking, doing, and feeling at each moment. <br />Typically performed in a usability testing lab setting (controlled environment), however it can be performed remotely.<br />
  4. 4. What is Usability Testing?<br />Observing an end-user perform scenario-based tasks<br />Participants will typically be asked to follow the “think-aloud protocol” which asks the participant to say whatever they are looking at, thinking, doing, and feeling at each moment. <br />Typically performed in a usability testing lab setting (controlled environment), however it can be performed remotely.<br />
  5. 5. What is Usability Testing?<br />The key stakeholders of an application/system to observe actual end-users interacting with the application/system (can be a prototype, developmental iteration, production-ready, and/or pre-existing).<br />Data collected can include:<br />subjective-anecdotal feedback<br />success rates<br />task times<br />error rates<br />subjective-satisfaction ratings<br />
  6. 6. When can it be most beneficial?<br />Early stages of project requirements gathering;<br />Early stages of project design;<br />Throughout development;<br />Existing applications / systems<br />
  7. 7. Who can be involved?<br />End-users<br />Key Stakeholders<br />Project Managers / Consultants<br />Technical Leads<br />Developers<br />UI Engineer<br />
  8. 8. Who can it be most beneficial to?<br />End-users<br />Key Stakeholders<br />Project Managers / Consultants<br />Technical Leads<br />Developers<br />
  9. 9. How is it accomplished?<br />Meeting to determine: <br />application / system to test<br />specific tasks to test<br />who the target end-users are to test<br />timeline for conducting usability testing (pre & post)<br />Draft scenario-based tasks for testing<br />Recruit & schedule testing participants<br />Run through of scenarios with actual testing equipment/systems/applications<br />
  10. 10. How is it accomplished? <br />Invite observers for testing (stakeholders, PM, TL, Dev Team, etc.)<br />Conduct Usability Testing with observers<br />Testing debrief with all observers<br />Analysis & report deliverable, if needed<br />
  11. 11. Format - Overall<br />Planning & Preparation<br />Testing<br />Debrief & Data Analysis<br />
  12. 12.
