TheService Catalog(to request IT services, software, and hardware).
TheKnowledge Base(to search for articles and solutions).
Viewing and tracking submitted requests and incidents.
Submitting new incidents or requests.
Since it is meant forall users, it does not require any additional roles beyond the default ones given to employees or customers.
