Use collaboration nodes to model interactions within a white box pool that depicts interactions between participants. The nodes show activities that take place and the flow between them. These nodes (collaboration) are not executed as part of the process; they are for informational use only. You can create message flow between these nodes and the nodes in the primary process to see all the parties involved and the messages sent between them.

For example, in the Loan Request map, the white box pool represents the Credit Check activity. Within the white box pool, collaboration nodes represent activities, such as Validate Address and Check for Outstanding Debts.
