A participant defines a partition of the actions of a process that will be assigned to a same agent.A participant enables:
• Assignment of a group of operations to one or to several enterprise org-units.
• Representation of a unit external to the process with which the process communicates by means of message flows.
Organizational process participants may be associated to different object types, but org-units are privileged.
An org-unit represents a person or a group of persons that intervenes in the enterprise business processes or information system. An org-unit can be internal or external to the enterprise. An internal org-unit is an organizational element of enterprise structure such as a management, department, or job function. It is defined at a level depending on the degree of detail to be provided on the organization (see org-unit type). Example: financial management, sales management, marketing department, account manager. An external org-unit is an external entity that exchanges flows with the enterprise. Example: customer, supplier, government office.
