Quantitative Risk Analysis
Quantitative Risk Analysis is a technique used to numerically estimate the probabilities and potential impact of individual risks on a project or organization. This method requires assigning numerical values to risk probabilities, as well as the consequences of those risks. The main advantages of quantitative risk analysis include the ability to make use of historical data, providing a consistent and standardized means of comparing risks, and allowing for more objective decision-making. This approach can be particularly useful for large-scale projects or highly regulated industries, where precise data and detailed risk assessments are required.
Guide to Quantitative Risk Analysis
Importance: Quantitative Risk Analysis is an integral component of any successful risk management strategy. It informs decision-making by providing numerical estimates of the likelihood and potential impact of risks, helping organisations to prioritize their risk mitigation efforts.
What it is: Quantitative Risk Analysis is a method for numerically analyzing the probability and impact of risks to inform decisions. It involves identifying potential threats to a system or process, estimating the probability of these threats materializing, and quantifying the potential losses if they do.
How it works: The process generally involves several steps. First, potential risks are identified. Then, their likelihood and potential impacts are estimated using data from historical incidents or expert opinion. Finally, these values are combined to calculate the overall risk level. This is often represented as a monetary value, allowing for easy comparison of different risks or mitigation strategies.
Exam Tips - Answering Questions on Quantitative Risk Analysis: When answering questions regarding Quantitative Risk Analysis, remember the following points:
- Understand the concept: Make sure you have a solid understanding of the concept, including its purpose and steps.
- Interpret the data: Be able to interpret the risk analysis data presented to you, this may include probability distributions or loss exceedance curves.
- Application of Knowledge: Questions may test the application of knowledge. You might be asked how you would allocate resources based on a given risk analysis, or to critique a completed risk analysis.

Test your knowledge of Amazon Simple Storage Service (S3)
Question 1
You are the project manager in charge of building a bridge. A potential risk that could delay the construction timeline by 15 days has been identified, and the probability of this risk is 0.15. What is the expected time delay caused by this risk?
Question 2
A software development company is analyzing the probabilities of encountering risks in its upcoming project. The risks identified include delayed deliverables (0.3), budget overruns (0.2), and personnel attrition (0.1). What is the joint probability of all three risks occurring?
Question 3
In a project to build a hotel, you have recognized a risk that can delay the project by 40 days with a 0.2 chance of occurrence. What is the expected time delay due to this risk?
