**Path: AC User Management > Organization**
digiRunner adopts organizational hierarchy to manage API visual authorizations, and achieves comprehensive management of data permissions and function permissions based on the controls over role functions; the principle is that the upper-level personnel may only view the API of the lower-level personnel under their organization.
Take the figure below for example.
Personnel A belongs to the organization unit *Department of Health*, so personnel A can view the information of lower-level *Physician* and *Administrative Assistant*.
Personnel B belongs to the organization unit *Department of IT* > *System Development Center*, therefore, personnel B cannot see the information of the parallel organization *Data Govemance Center*, and cannot see the information of the upper-level organization *Department of IT*.

The  can be used to expand / collapse the sub-organizations under them.

If external personnel has the need to use the system console, another organization for external personnel can also be created and accounts can be created.
