What worked?
… approaching people.
… find out about users mental model.
… find out if we cut out to many features.
… see how users use their phone.
What did not work?
… get users deeply involved.
… dig deep.
… build segments.

What worked?
… approaching people.
… fast feedback on different design
soulutions.
… notice when people expect the feature
in their search flow.
What did not work?
… get more than 3 min of users’ time.
… get detailed feedback.
… consistent “question stream”.
… get user’s imagination going.
1. It won’t answer all your questions.
2. Be specific.
3. It’s not for everyone.
