- 11. What are your business goals? What are your users’ top tasks? What do users do most often on your site?
- 12. How to find Top Tasks? Identify top search terms Identify most visited pages Speak to Customer Service team Examine competitor’s site Get users to rank list of tasks
- 13. Writing Tasks into Task Scenarios Task: “Search for a horror show from Japan” Task Scenario: Must represent realistic user goal “It is the Halloween holiday and you invited a group of friends to your place. You plan to watch a horror show with them. Find a Japanese horror show.
- 14. Tips for writing good task scenarios Task is unambiguous and easy to understand. There is a clear end point to determine if task is a success or failure Avoid hidden clues Not biased Avoid stacked tasks Make the task neutral Don’t be funny or assume about what users will find funny
- 15. Your friend recommended you a new show that is still airing on TV. Find information about the new show. What’s wrong?

- 17. Recruit Know your end users. Demographic/gender/age? What form of testing? (in-person/remote) External recruiting agency or recruit by yourself?
- 18. Screening users Screen users’ behavior instead of their frequency of use (ex. “What things do you do online?” (list activities with frequency) instead of “Are you a frequent internet user?”) Users who work in certain companies (competitors) Users whose job are related to research Other specific criteria, etc.
- 19. How many users should I test? else 5 is enough (to capture usability problems) *iterative process *not for quantitative studies As many as possible
- 20. Write 3 Task Scenarios 10 mins Activity 1:
- 21. 3. MODERATE
- 22. Roles to play as a moderator 1. Give instructions 2. Inform users to think aloud and remind them 3. Inform them that there’s no right or wrong answer 4.

Directive tasks ( ....Find the working hours of the restaurant for Sunday)
- 24. Types of activities Wrapping up (On a scale of 1- 10, how would you rate the ease of use for this website? What should we do to make it 10 out of 10? Do you have any questions or feedback?) Post-site questionnaire - System Usability Scale - Post-site word choice
- 25. Run a usability testing 20 mins (10 mins per individual) Activity 2:
