  9. 9. How – Expert ReviewsPros:• Catches many usability problems before testing takes place• Cost effective• Actionable report for project teamProblems:• Needs to be followed up by user testingWhy?• How do we compare?• What’s working, what’s not?

  11. 11. How – Usability methodology• Concurrent Think Aloud o Encourage the user to say what they are thinking o Use unfinished questions, you were expecting o Gets feedback there and then• Retrospective Think Aloud o Play back video or repeat a path how to the user and ask them what why what they were thinking at the time task end wrap o Allows user to naturally complete the task

  17. 17. How – Field StudiesPros:• User is relaxed in their own environment• Can be done in the office environment• Moderator gets to observe the system used in situationProblems:• Investment in time to go out of the office• Testing will not be controlledWhy?• What external effects are there on the user journey?
  18. 18. How – Moderation• Be neutral • Don’t blame the user or defend the design• Acknowledge • Let the user get on with the task but encourage them if necessary • Listen and react• Know when to intervene • Don’t let a user suffer but a user struggling to complete a task can give you the evidence that you need• Users who want to talk (and not want to talk)• Watch your language (and your body language)• Open ended questions
  19. 19. How – Moderation• The alternative guessing game – One person is the moderator – One person is the user• Rules – Only questions that will result in an answer of more than 3 words – Can’t ask a question that will result in the answer ‘yes’ or ‘no’ – Try and ask as few questions in order to guess the object
  20. 20. How – Moderation – How to ask why• Open ended questions• What worked? • Can • Would • What• What didn’t work? • Is • Did
