When performing a countermeasures cost-benefit analysis, which two of the following questions are useful?

When conducting a countermeasures cost-benefit analysis, it's crucial to evaluate how effectively the proposed options can meet the fundamental objectives of counterterrorism measures: delay, deter, detect, defend, or destroy potential threats. This assessment provides a clear understanding of the effectiveness and efficiency of each countermeasure. The degree to which a countermeasure can achieve these outcomes directly impacts the decision-making process regarding resource allocation and prioritization of efforts to mitigate risks.

Analyzing the effectiveness in terms of these critical functions enables the decision-maker to weigh the potential benefits against the costs, contributing to a more informed choice about which measures to implement. Therefore, assessing how well each option meets these critical functions is not only relevant but essential to a comprehensive cost-benefit analysis.

On the other hand, other choices focus on different aspects that, while important, do not directly address the core effectiveness of countermeasures in terms of their threat mitigation capabilities. Evaluating asset values against protection costs, implementation timelines, and analysis frequency are certainly useful considerations, but they do not directly relate to the immediate effectiveness of countermeasures in addressing potential threats.
