Work groups are a primary base for many standard reports.
If you want, you can set up work groups to correspond to a fourth level in an organizational hierarchy (below organization units). However, work groups can cross organization units and divisions — PRPC doesn't require any correspondence between work groups and divisions or organization units.
A work group data instance can identify one user who is the work group supervisor. The system can use supervisor information in a work group for both routing tasks and notification tasks — two types of tasks used in flows.
