Not only is the hour of day identified, but also the classification by the type of call is
identified. It is worth noting that using the dashboard approach, drill down processing is a

processing to investigate more thoroughly each class of call that came in during any given
hour.
A related type of information that is available is the type of phone call by day of the
week. This type of information is seen in Fig. 10.3.10.
