Where does the "Department" name for an individual come from when it is displayed in the online Directory?

We have a long list of valid orgs. This list contains the legal name, banner org/department code and an ID (used to keep track of the org/department) for every UIC org/department.

When an affiliation is assigned to an individual the pbcontact selects which org/department the affiliation is under. When this is done the affiliation is linked to the org/department in our list. So when a org/department name is changed, it is changed in one location and displayed for all individuals associated with that org/department.
