                       Figure 7-6 shows a simple EPC diagram for part of the Fitter expense-reporting
                   process. EPC diagrams begin and end with events. Furthermore, events must be followed
                   by functions, and functions must be followed by events.

                       In addition to direct connection of events to functions, EPC diagrams employ three
                   types of branching connectors. Branching occurs when logic either comes from more than
                   one source or proceeds to more than one potential outcome. The three connector types
                   are AND, OR, and Exclusive OR (XOR). Figure 7-7 shows how the AND connector
                   functions. The figure indicates that the expense report must be recorded and a hard copy
                   must be filed.
