Usability test
A usability test observes suitable people performing realistic tasks. It examines use and needs a clear scope and well-documented notes.
A usability test examines how a product is used by having suitable people perform realistic tasks. Observers can note the paths people choose and where they get stuck. In a moderated test, someone accompanies the session without demonstrating the solution.
Example and interpretation
In a hypothetical portal test, the task is to find the valid delivery terms. The instruction names the goal but not the menu route. Moderator hints are recorded so that assisted and independent completions remain distinguishable.
The observations can justify revisions. They are neither a vote on appearance nor a licence for unrestricted generalisation. A successful run also replaces neither technical checks nor an assessment of accessibility against standards.
