The primary focus of a risk practitioner when validating a risk response action plan should be that the risk response reduces risk to an acceptable level. A risk response action plan is a document that describes the actions or measures that are taken or planned to modify the risk, such as reducing, avoiding, transferring, or accepting the risk1. Validating a risk response action plan means verifying whether the plan is feasible, effective, and efficient in addressing the risk2. The main objective of validating a risk response action plan is to ensure that the risk response reduces risk to an acceptable level, which is the level of risk that the organization is willing to tolerate or bear, based on its risk appetite and risk criteria3. Reducing risk to an acceptable level means that the risk response actions can lower the likelihood or impact of the risk to a point where the risk does not pose a significant threat or challenge to the organization’s objectives, operations, or performance. Reducing risk to an acceptable level also means that the risk response actions can balance the benefits and costs of the risk response, and that they can provide a reasonable assurance of the risk management effectiveness and efficiency4. The other options are not the primary focus of a risk practitioner when validating a risk response action plan, as they are either less relevant or less specific than reducing risk to an acceptable level. Quantifying risk impact is a component or element of validating a risk response action plan, notafocus of it. Quantifying risk impact means measuring or estimating the potential effects or consequences of the risk on the organization5. Quantifying risk impact can help to evaluate the severity and priority of the risk, as well as to compare the risk against the risk criteria and the risk appetite. However, quantifying risk impact is not the primary focus of a risk practitioner when validating a risk response action plan, as it does not address the feasibility, effectiveness, or efficiency of the risk response actions, or the level of risk reduction that they can achieve. Aligning with business strategy is a secondary or incidental benefit of validating a risk response action plan, not a primary or essential focus of it. Aligning with business strategy means ensuring that the risk response actions are consistent and coherent with the organization’s goals and values6. Aligning with business strategy can help to integrate the risk response actions with the organization’s culture and governance, as well as to support and enable the achievement of the organization’s mission and vision. However, aligning with business strategy is not the main focus of a risk practitioner when validating a risk response action plan, as it does not indicate the feasibility, effectiveness, or efficiency of the risk response actions, or the level of risk reduction that they can achieve. Advancing business objectives is a tertiary or indirect outcome of validating a risk response action plan, not a primary or direct focus of it. Advancing business objectives means contributing to the improvement and enhancement of the organization’s performance and results7. Advancing business objectives can help to create value and deliver benefits for the organization and its stakeholders, as well as to optimize the use of the organization’s resources and capabilities. However, advancing business objectives is not the main focus of a risk practitioner when validating a risk response action plan, as it does not address the feasibility, effectiveness, or efficiency of the risk response actions, or the level of risk reduction that they can achieve. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 2, Section 2.1.8, Page 61.
