Flow objects have three types: Events that represent something that occurs during
the normal process execution; events have a cause (trigger) or an impact (result).
Different icons allow us to define start, intermediate, or end an event. Internal
market (and this is another detail level) represents triggers that define the cause of
the events. For example, start event may be a circle without any icon or may have
an envelope icon to represent that the process starts when a message is arriving. A
complete set of events and icons are shown in Figure 2.
Another type of Flow Object is activities, which is generic work that a company
performs.
