To what events must the ticket$-$processing system

respond?

List each event, the type of event, the

resulting use case, and the actor$($s$).$ Think carefully

about who the actors are. Does the officer directly

enter the ticket into the system? Or does a state patrol

clerk do it when the paper ticket is received from

the officer? The existing system uses paper forms, so

for now assume the state patrol clerk enters all of the

information. A new system would use the same use

cases, but opportunities for efficiency and accuracy

would lead to changes in who the actors are.
