The system offers an organization structure that has three levels. The top level, defined by this form, is the organization; the middle level defines divisions, and the lowest level is organization units.
As a best practice, create a work queue named default@organization for each organization in your system, and have someone review the assignments in that work queue from time to time. Certain standard routing activities use this work queue as a last resort when no other suitable destination can be found for an assignment.
You can use the Organization Setup landing page tab to create an organization structure for your company or for experimentation and learning. See Org & Security category — Organization landing page.
