LET’S DO SOME USABILITY
What makes a system usable?
What makes a system usable?
• Visible System Status• System/Real World
Alignment• User Control and
Freedom• Consistency and
standards• Error Prevention
• Recognition over Recall• Flexibility and Efficiency• Aesthetic and
Minimalist Design• Help Users recognize,
diagnose, recover from errors

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
