Figure 3 only has two reporting use cases (``Occupancy Report'' and ``Report Monthly Sales'') although some others may also be regarded as reports (for example, ``Report Seat Availability''. Other reporting use cases might include: ``Occupancy Report by Theatre'', ``Occupancy Report by Event, ``Occupancy Report by Performance'', ``Occupancy Report by Week'', all of which would be of interest to the Business Manager. However similar kinds of reports (almost certainly organised differently) would be useful to the busy Ticket Seller having to answer questions of the form ``Are the plenty of free seats for tomorrow's performance of Dracula?''.
