9. What Worked Semi-structured interviews
HCI Experts
Domain Experts
Expert Users
Audio recording, taking notes afterward
Paper and PowerPoint prototypes

10. What Didn’t Work Transcribing audio interviews verbatim
High-fidelity prototypes
Never meet user expectations
Result in discussion of meaningless features
Changing the interview protocol during the study
This may not be avoidable in exploratory studies

11. What’s Hard Work
Distilling quantifiable facts from semi-structured interviews
Making sure users understand low-fidelity prototypes the same way you do
Written interviews
Requires follow-up live interviews
You may never get the results

12. What I Haven’t Tried (yet)
Broad Surveys
Lab-based Studies
Diary Studies
Field studies (tag-along)

13. Conclusions Research is always hard! It’s relatively easy to:
Schedule interviews
Take notes
Get a good feeling for the subject
It’s relatively hard to:
Talk on the same wavelength as your subjects
Distill useful facts from interview notes
Write up your findings coherently
