The risk practitioner should explain to senior management that mitigation plans for threat events should be prepared in the current planning period, as this would demonstrate a proactive and responsible approach to risk management. Mitigation plans are documents that outline the actions and resources needed to reduce the likelihood and/or impact of a specific risk scenario. Mitigation plans should include the following elements:
Risk scenario description and risk ID
Risk owner and other stakeholders
Risk response strategy and objectives
Risk response actions and tasks
Resources, costs, and benefits
Roles and responsibilities
Timeline and milestones
Performance indicators and monitoring mechanisms
Contingency plans and triggers
Mitigation plans help to address the gap between the current and desired risk levels and align the risk response with the organizational risk appetite and objectives. Mitigation plans also facilitate the communication, coordination, and collaboration among the risk owners and other stakeholders involved in the risk response process. Mitigation plans should be prepared in the current planning period, as this would allow the organization to act timely and effectively in the event of a low frequency threat event. Preparing mitigation plans in advance would also help to avoid or minimize the potential harm to the organization and its reputation.
The other options are not the best ways to communicate the associated risk to senior management. Explaining that this risk scenario is equivalent to more frequent but lower impact risk scenarios may not accurately reflect the true nature and severity of the risk. Explaining that the current level of risk is within tolerance may not convey the urgency and importance of addressing the risk. Explaining that an increase in threat events could cause a loss sooner than anticipated may not provide a clear and actionable solution for the risk.
