Your next step, after drawing the decomposition diagram, is creating the event-response or usecase list. There should be a use case for each event initiated by an external agent. Temporal events should also be shown. For each external agent, there should be at least one use case. Start a partial use-case table that includes the events OTHER DIVISION SENDS REQUEST FOR INVESTIGATION and FIELD OFFICE SENDS COMPLETED INVESTIGATION REPORT.

Also include the event GENERATE OPEN/CLOSED/IN PROGRESS CASE LISTING REPORT.
