All information recorded must include audit information about when a record was created, modified, completed and authorised and by whom. This may also include proof of an attestation i.e. authorisation and the source system where the information was recorded.
Audit information is about the provenance of information record itself rather than information about who performed an activity or if they needed support to capture the information.
For more information about audit and provenance see the audit and provenance conceptual model.
