A conversation diagram focuses on the communications between participants. You cannot create or display processes or choreographies in this diagram.
In the following example, the various conversations associated with deliveries from a supplier to a retailer are analyzed:
| Tool | Description | 
|---|---|
|  | Participant - Organization, business unit, or role (see Participants (BPMN)). | 
|  | Conversation Node - Sits between two participants and collects the messages exchanged between them (see Conversation Nodes (BPMN)). | 
|  | Conversation Link - Links participants via a conversation node (see Flows and Links (BPMN)). Click in one participant and draw a link to another participant to automatically create a conversation node between them. |
