EXAMPLE OF A BUSINESS PROCESS DIAGRAM
Participants include people, systems, organizations, and machines•
BPMN provides notation to identify both the organization and the departments or individual actors participating in
a process
•
The organization is identified by a pool and the department is identified by lanes within the pool•
•
Every diagram has at least one pool. If there's only one pool, the pool may be presented without a boundary •
Activities can be assigned to only one participant, and thus may appear in only one pool or lanes •
There is one start event per pool and at least one end event •
Which means one task cannot be performed by two departmentsâ—‹
Each task is located in only one lane•
The sequence flows can cross lane boundaries but do not extend beyond one pool•
IDENTIFYING PARTICIPANTS IN BUSINESS PROCESS DIAGRAMS
Activities within a pool are organized by sequence flow, but the interactions between pools are represented as

Document Summary
Icons placed in events are used to further define event categories such as message, timer, or error events. Activities represent specific steps in the business process. Each activity is described with a short verb within the rectangle. An activity can be a single action or logical combination of actions. Sequence flows are represented by arrows to indicate the progression of activity within the process. Go from left to right, then top to bottom. Gateways show process branching and merging as the result of decisions. Gateways appear as pairs on the diagram with one showing when it branched, and another shows the merging of the process branches. Annotations allow the modeler to add additional descriptive information to the model. If there"s only one pool, the pool may be presented without a boundary. Activities can be assigned to only one participant, and thus may appear in only one pool or lanes.
