Hotel booking process design & usability
Travel UCD – February 2003
9.1.1.3 Task failures occurring in the usability test
Every task failure made by a user during a usability test is an opportunity
to learn more about the
design.
For this evaluation, we recorded task failures that fell into the following category:
• Unable to answer the
question set as the task
If the user created a budget, but used an incorrect set of dates (such
as for the date of the test
rather than the date for the proposed trip), this was not counted as task failure.

Each of the four sites was visited 12 times, so the maximum score could be 12 errors (maximum
one error per task).
For Wotif and Downtown Disney, the scores between the two tasks have
been combined. Once the user had failed the first
task on either of these sites, they were in no
position to answer the second task without any explanation of how the website worked.
