Explanation
A process diagram is a kind of asset that the BA should provide to fully specify the approval requirement. A process diagram is a visual representation of the sequence of activities and decisions involved in a business process or a system. It shows the inputs, outputs, roles, tasks, events, conditions, and flows that occur in each step of the process. A process diagram can help the BA specify the approval requirement by showing:
Which incident-related activities require approval and confirmation
Who are the authorized personnel for each activity
What are the criteria and triggers for approval and confirmation
What are the outcomes and exceptions of approval and confirmation
A process diagram can also help the EA compare the existing application and the new application by showing the similarities and differences in the process flows, data sources, and user interfaces.
