Defining Process Events
The events enabling representation of facts occurring during process execution.
An event represents a fact occurring during execution of a process, for example a new contract concluded with a supplier. An event marks the impact on process progress of a phenomenon internal or external to the process. There are different natures of events: start events, catch events, throw events and end events.
Events can be used:
• Within a process to define facts internal to the process.
• Outside a process to describe causes and effects of events of the process depending on its use context.
