Assume the FieldOfficer can invoke a Help feature when filling an EmergencyReport. The HelpReportEmergency feature provides a detailed description for each field and specifies which fields are required. Modify the ReportEmergency use case (described in Figure 4-10) to include this help functionality. Which relationship should you use to relate the ReportEmergency and HelpReportEmergency?
What will be an ideal response?
The ReportEmergency use case does not need to be modified when the HelpReportEmergency is written as an
extension. The advantage of writing behavior such as help and exceptions as extensions is that they can be reused in
different use cases or in different steps of a single use case. Below is a sample solution with the <
relationship.
