A Pool in a BPMN collaboration diagram represents a participant of a collaboration. A Pool can have its inner process flows defined. You can add the elements from a BPMN Process diagram to a pool. You can also hide the pool details by displaying a “black box” pool. A Pool can also have inner lanes.
