The most appropriate action for the risk manager to take after undertaking a risk assessment of a production system is to inform the process owner of the concerns and propose measures to reduce them, as the process owner has the authority and responsibility to manage the production system and its associated risks and controls, and to decide on the optimal risk response. Recommending a program that minimizes the concerns of that production system, informing the IT manager of the concerns and proposing measures to reduce them, and informing the development team of the concerns and together formulating risk reduction measures are not the most appropriate actions, as they may not involve the process owner, who is the key stakeholder and decision maker for the production system and its risks. References = CRISC Review Manual, 7th Edition, page 101.
