  7. Whatyou’llneed listen observe Shut up Or ask 5x record Yourapp (as early as possible)Define the most important tasks to complete Defineyoursuccesscriteria Testers Select a few representativepeople fromyourtarget audience Withtheirdevice (yourmumisn’t OK) Notepad Pen (Or recorder)

  8. Test itsusability • Introduceyourself • Alwaysexplainthatyou are testing the app, not the user. (Eventually, lie and saythisissomeoneelse’sapp) • Alwaysstartat the same point • If possible, test in context • Avoidbiases: don’tgive the answers to your questions! • Askpeople to thinkaloud as theyperformyourtask • Listen, and ask more. • You can come back to some points later

  9. If theyask… Whathappens if I click here? What do youthinkwouldhappen?  I thinkitwould do so and so. Let’sfind out then Oh! Hum… what’s on yourmind?

  13. Measureusability and satisfaction • Didtheysucceed to completethe task? • How fast? How easily? • Didtheysmile? • Didthey struggle? If so, where, how often?

  14. Pitfalls to avoid Don’tgive the answer in the question • Use a script Don’tgive clues on how users are doingduring the task (Userswant to makeyou happy, sotheywill look for clues in your body language or thingsyousay.) • Stayneutral, neversay ‘thisis good’ but rather ‘Ok, thanks’ Don’t change your design entirelyafter 1 user test (itmightbe an accident, tryanother one first) Don’treuse the same participant in subsequent tests

  15. Do youwant more? Ask me or look at the referencematerial
