CRA - Certified Risk Architect Quantitative Risk Analysis Questions and Answers 1

Question 1

A project manager is analyzing a critical risk with a 20% probability of occurrence. If the risk materializes, it will result in a project cost overrun of $150,000. If the risk is avoided, there is a 10% chance of realizing a $50,000 cost saving. What is the Expected Monetary Value (EMV) of this risk?

Accepted Answer

-$25,000

Answer

Expected Monetary Value (EMV) is calculated by multiplying the probability of each outcome by its impact and summing the results. For the negative outcome: 0.20 * (-$150,000) = -$30,000. The probability of the risk not occurring is 80% (100% - 20%). Within this 80%, there is a 10% chance of a positive outcome: 0.80 * 0.10 * $50,000 = $5,000. The total EMV is -$30,000 + $5,000 = -$25,000.

Question 2

Which of the following quantitative risk analysis techniques is best suited for modeling the combined effect of uncertainties in multiple project variables to estimate the probability of achieving cost and schedule objectives?

Accepted Answer

Monte Carlo Simulation

Answer

Monte Carlo Simulation is a technique that runs a project model thousands of times, each time with different random values for the uncertain variables (like task durations or costs). This process generates a probability distribution of possible outcomes for the entire project, making it ideal for understanding the combined impact of multiple uncertainties on objectives like cost and schedule.

Question 3

A risk architect is using a sensitivity analysis to identify which project risks have the most significant potential impact on the project's overall outcome. The results are typically displayed in which type of chart?

Accepted Answer

Tornado Diagram

Answer

Sensitivity analysis results are most commonly displayed using a Tornado Diagram. This chart compares the relative importance of different variables by showing bars of varying lengths, with the most impactful variables at the top, resembling a tornado.

Question 4

A company is deciding whether to develop a new product line internally or to acquire a smaller company that already has a similar product. This decision involves multiple stages, uncertain outcomes, and associated costs and payoffs. Which quantitative risk analysis technique is most appropriate for visualizing and evaluating these different paths and their potential outcomes?

Accepted Answer

Decision Tree Analysis

Answer

Decision Tree Analysis is specifically designed for situations involving sequential decisions and their potential outcomes under conditions of uncertainty. It provides a visual, tree-like model of decisions and their possible consequences, including chance events, resource costs, and utility, making it perfect for comparing complex strategic choices like 'build versus buy'.

Question 5

In the context of quantitative risk analysis, what is the primary advantage of using numerical data over subjective ratings (e.g., high, medium, low)?

Accepted Answer

It provides an objective, measurable basis for comparing and prioritizing risks.

Answer

The fundamental benefit of quantitative risk analysis is that it uses measurable, numerical data to evaluate risks, providing an objective foundation for decision-making. This allows for a more precise comparison of risks, cost-benefit analysis of mitigation strategies, and clearer communication with stakeholders, unlike the subjective nature of qualitative ratings.
