Usability “heuristics”• There are certain characteristics of usable
systems • Individually and of themselves, they don’t make
a system usable • But if they’re absent, the system will not be
usable.

How many participants?
Reporting
@gerrygaffney
Encourage observers
Invite people to observe Debrief with others Spread the word Avoid usability-testing-as-weapon.
@gerrygaffney
Good facilitation
Listen Allow plenty of time for people to think Don’t prompt Use neutral body language Encourage people to think aloud Finish on time!
@gerrygaffney
Moderated, unmoderated, remote, multi-party, automated, A/B testing, 5-second tests, RITE…
@gerrygaffney
Contextual enquiry, surveys, diary studies (“cultural probes”), card-sorting, heuristic evaluation, web analytics… lots of different user-centred design techniques
Just do it!
