Integration and Discussion of Results
The illustrated walkthrough was only conducted on
one of many tasks that are likely to be done by the user. The information
obtained from the cognitive walkthrough (CW) is then forwarded to the designer
(who may or may not have been part of the design team). Clearly,
based on the CW the main problem lies in the need to clear forwarding before
specifying a new destination. Also, the template layout may be somewhat
confusing and problematic for the task. The designer can pursue one of
three remedies: providing training so that users will bring the right
goal structure to the task, supply prompt information that indicates to
the user of the need to clear forwarding, or changing the system so that
clearing is no longer required. The design alterations are not part
of the responsibility of the CW team but rather they are required to bring
forward the important information obtained from the forms from each task
and their interpretations.
The illustrated process would continue for all
the tasks analyzed and the designer would have to integrate and prioritize
each problem that is brought out by the CW.
