Getting Feedback

Quantitative Qualitative

Unmoderated

Moderated

What did we just do?

• Select a representative user• Ask the participant to perform a

representative task• Observe what the users do, where they

succeed. (Shut up and listen!)

NOW IT’S YOUR TURN…

• Partner with another person• Ask them to perform a task

– If you have something you’re building you want them to try, great!

– MegaBus: When is the cheapest time to ride to Chicago in the next 30 days

– Icgov.org: When will compost be available? Where can I get it• Observe, take notes

– Complete Task? Y / N / With Help– Time on Task– Errors

SO…HOW DID IT GO?

What’s the process?

• 5-10 users• Task completion rates, confidence intervals• Summarize, share, do something different
