BPMN Multiple Event
The BPMN Multiple Event article provides a detailed explanation of the multiple event BPMN element, including the definition, notation, rules, guidelines and examples.
The BPMN Multiple Event article delves deep into the intricacies and applications of the multiple event element as outlined in the BPMN 2.0 specification. The definition, notation, and rules sections offer a concise summary of the BPMN 2.0 Specification pertaining to the multiple event element. Meanwhile, the guidelines section presents a curated collection of best practices specific to the multiple event, showcasing its proper and effective utilisation in process modelling.
BPMN Definition
A Multiple Event is determined by an Event that specifies more than one Event Definition. This means that there are multiple triggers assigned to the Event. If used within normal flow, the Event can “catch” the trigger or “throw” the triggers. ~ BPMN Specification
BPMN Notation
The BPMN specification defines the different types of Multiple Event elements using the following description and notation:
Element | Description | Notation |
---|---|---|
Multiple Start Event | ||
Multiple Event Sub-Process Event (Interrupting) | ||
Multiple Event Sub-process Event (Non-Interrupting) | ||
Multiple Intermediate Catch Event | ||
Multiple Boundary Event (Interrupting) | ||
Multiple Boundary Event (Non-Interrupting) | ||
Multiple Intermediate Throw Event | ||
Multiple End Event |
BPMN Event Types
BPMN events represent various types of occurrences that affect the flow of a process, and they can be categorized based on their position and behavior in the process.
- Start Event: The Start Event indicates where a particular Process will start.
- Intermediate Event: The Intermediate Event indicates where something happens (an Event) somewhere between the start and end of a Process.
- End Event: The End Event indicates where a Process will end.
- Catching Events: Events that catch a trigger. All Start Events and some Intermediate Events are catching Events.
- Throwing Events: Events that throw a Result. All End Events and some Intermediate Events are throwing Events that MAY eventually be caught by another Event.
- Boundary Event: An Intermediate Event that is attached to the boundary of an Activity.
The following table illustrates how the different types of Multiple Events are grouped as per the BPMN Event types:
Catching Events | Throwing Events | |||||||
Start Event | Intermediate Event | End Event | ||||||
Standard | Event Sub-Process Interrupting | Event Sub-Process Non-Interrupting | Catching | Boundary Interrupting | Boundary Non- Interrupting | Throwing | Standard | |
