Problem
A heuristic evaluation of Connexions' help system revealed that
its navigation design would be cumbersome for users to locate the
targeted help content.
Solution - Procedure
- Planned the pre-redesign user testing
(scripts, tasks, and interview questions)
- Conducted the pre-redesign user testing
(N=9) and analyzed the results -- the resutls indicated
that on average users needed to spend more than two minutes
to find a help topic for most tasks.
- Prepared 96 topics based on the topics
in the current help system and topics that had been left
out but necessary.
- Asked Connexions team members (N=10)
to participate in the card sorting
-- each of them did the card sorting individually.
- Made a prototype for the redesign of
the help system
- Conducted the post-redesign user testing
(N=9) and made comparisons between
the pre- and post- redesign user performance -- the results
showed that the redesign successfully reduced the search
time
