1 Definition
An Event is a Process Action or a logical combination of Process Actions performed at a Time or Time Type.
2 Functional Requirements
Events involving no more than two Process Actions are listed in Table 1.
Table 1 – Basic Events
| Process Action1 | Operation | Process Action2 | Basic Event happens if |
| Process Action | The Process Action is performed. | ||
| NOT | Process Action | If the Process Action is not performed | |
| Process Action1 | AND | Process Action2 | If both Process Actions are performed. |
| Process Action1 | OR | Process Action2 | If at least one Process Action is performed. |
| Process Action1 | NAND | Process Action2 | If at least one Process Action is not performed. |
| Process Action1 | NOR | Process Action2 | If none of the Process Actions is performed. |
| Process Action1 | XOR | Process Action2 | If only one Process Action is performed. |
| Process Action1 | XNOR | Process Action2 | If one Process Action is performed and the other is not. |
and the characters If followed by Time, referring to a single Time, a Duration, or a recurring Time.
