"Conversation-Model.
The new Conversation-Model is used to model a "who with whom and what"-view of processes. All process participants can be included in a compact form of modeling as long as denoting which communication is involved.
Process participants are represented as Pools (collapsed...) in Conversation-Models. The Communication-Shape defines a set of logically related message exchanges which are tied to Pools via Conversation-Links. If there is a multi-instanced Pool (also introduced with BPMN 2.0) involved, a Forked Conversation-Link is used for it.
Furthermore Sub-Conversations can be used to define abstractions." [en.bpmn-community.org/ tutorials/ 34/ ]

This BPMN (Business Process Model and Notation) conversation diagram sample shows the franchisee recruitment and training workflow.
"Franchising is the practice of using another firm's successful business model. ... For the franchisor, the franchise is an alternative to building 'chain stores' to distribute goods that avoids the investments and liability of a chain. The franchisor's success depends on the success of the franchisees. The franchisee is said to have a greater incentive than a direct employee because he or she has a direct stake in the business.
Essentially, and in terms of distribution, the franchisor is a supplier who allows an operator, or a franchisee, to use the supplier's trademark and distribute the supplier's goods. In return, the operator pays the supplier a fee." [Franchising. Wikipedia]
