| Before, the initial system design contained
400 screens. The logic was based on an event metaphor.
Users had to approve the system but were not able
to decide for themselves. We decided to do a task
analysis of the main users.
After one week, we had a model that provided a
framework for 90% of the occurrences. |
After, we have
been able to demonstrate the task is non linear.
A client request may lead to a combination of transactions.
Our redesigned system requires only two screens
for the task of understanding 90% of the calls and
seven transaction screens. |
