Who has the primary responsibility to report the authorization decision? Response:

The Authorizing Official (AO) is ultimately accountable for the authorization decision, while the Authorizing Official Designated Representative (AODR) supports the AO in fulfilling this responsibility, including formal reporting of the decision. Together, they ensure the decision is communicated to relevant stakeholders.

The Common Control Provider (CCP) manages shared security controls, and the Information System Owner (ISO) manages the system, but neither is primarily responsible for formally reporting the authorization decision itself.

While the AO makes the ultimate decision, the ISO is responsible for the system's operational security and risk management, not the formal reporting of the authorization decision.

The ISO manages the system and its risks, but the formal reporting of the authorization decision rests with the AO and AODR.
