Draft a simple question to test the feature in question.
e.g. Take a look at these tab headings - what would you expect these tabs to contain?
OR, Can you find the links on this page (to see if they scrub for links)
OR, navigate several steps down into a site, then navigate back up (this was to see if they edited or looked at URLs to see where they were in the site)
Select a random sample of people to go and ask.
Take a notepad & pencil with you, and note down:
- what level of user you consider them to be (expert, average, novice)
- which version of the page you are testing (if there's more than one version)
- note down what they do or say in response to your task or question
- note down any other comments they make
All hallway usability test results should be anonymised.
