Concepts
When studying for the PMI Risk Management Professional (PMI-RMP) exam, understanding how to perform risk weighting and calculate risk priority is essential.
Risk Weighting
Risk weighting involves assigning weights to different risks based on their potential impact on a project. The weight of a risk usually corresponds to its potential impact and the likelihood of it occurring. Risk weighting allows for a more effective prioritization and management of risk.
Risk Priority
On the other hand, risk priority refers to the order in which risks should be addressed based on their overall impact on the project. Risk priority can be determined by multiplying the weight of the risk by the probability of its occurrence.
Example 1
Let’s assume we have three potential risks to a project: Risk A, Risk B, and Risk C. Each risk is given a specific weight:
- Risk A: 3
- Risk B: 2
- Risk C: 1
And the probability of each risk occurring:
- Risk A: 0.2
- Risk B: 0.3
- Risk C: 0.5
The risk priority score for each is then calculated as follows:
- Risk A: 3 * 0.2 = 0.6
- Risk B: 2 * 0.3 = 0.6
- Risk C: 1 * 0.5 = 0.5
From the calculation, Risk A and Risk B are seen as the top priority.
Outline Table
| Risk | Weight | Probability | Risk Priority Score |
|---|---|---|---|
| A | 3 | 0.2 | 0.6 |
| B | 2 | 0.3 | 0.6 |
| C | 1 | 0.5 | 0.5 |
Bear in mind, this is a simple example and real project risks can be much more complex, involving multiple factors and interdependencies amongst risks.
Example 2
Let us consider another example where we have five risks: Risk P, Q, R, S, and T.
| Risk | Weight | Probability |
|---|---|---|
| P | 5 | 0.1 |
| Q | 4 | 0.2 |
| R | 3 | 0.3 |
| S | 2 | 0.4 |
| T | 1 | 0.5 |
The risk priority score for each risk is then calculated as follows:
| Risk | Risk Priority Score |
|---|---|
| P | 5 * 0.1 = 0.5 |
| Q | 4 * 0.2 = 0.8 |
| R | 3 * 0.3 = 0.9 |
| S | 2 * 0.4 = 0.8 |
| T | 1 * 0.5 = 0.5 |
From the calculation, Risk R should be the highest priority.
Performing risk weighting and calculating risk priority are critical steps in managing risk effectively. They form part of the larger process of risk assessment, which also involves identifying risks, assessing their impacts and likelihoods, developing responses and monitoring and reviewing risks.
To carry out these tasks effectively, a risk management professional needs to have a good understanding of the project, including its objectives, constraints, stakeholders and internal and external environments. They also need good judgment, as risk management often involves making decisions in the face of uncertainty.
As you study for the PMI-RMP exam, ensure to become proficient in these skills, as they are critical to both passing the exam and being a competent risk management professional.
Answer the Questions in Comment Section
True or False: Risk weighting involves assigning a numerical value to each identified risk based on its magnitude and probability of occurrence.
- True
- False
Answer: True
Explanation: Risk weighting is the practice of assigning a numerical value to each risk identified in risk management, based on its magnitude and potential impact on a project.
Which of the following factors are considered when calculating risk priority?
- a) Impact of the risk
- b) Probability of the risk occurring
- c) Risk response strategies
- d) Both a and b
Answer: d) Both a and b
Explanation: Risk priority is determined by both the impact of the risk, how detrimental it will be to the project, and the probability of the risk occurring. Risk response strategies are part of risk management, not risk prioritization.
True or False: The higher the risk priority number (RPN), the lower the priority of the risk.
- True
- False
Answer: False
Explanation: The higher the risk priority number (RPN), the higher the priority of the risk. Risks with high RPNs are prioritized and addressed first in risk management planning.
Which of the following is NOT a method used to perform risk weighting?
- a) Risk Impact/Probability Chart
- b) CPA (Critical Path Analysis)
- c) FMEA (Failure Modes and Effects Analysis)
- d) SWOT Analysis
Answer: d) SWOT Analysis
Explanation: Risk Impact/Probability Chart, CPA, and FMEA are methodologies used in risk management for analyzing and calculating risk. SWOT analysis is a strategic planning tool not typically associated with risk weighting.
True or False: All risks should be treated as external risks when performing risk weighting and calculation of risk priority.
- True
- False
Answer: False
Explanation: Some risks are internal, coming from within the project or organization, while others are external, originating from outside the organization. Both types should be considered when performing risk weighting.
What does the acronym RPN stand for in risk management?
- a) Risk Probability Number
- b) Risk Priority Number
- c) Risk Potential Number
- d) Risk Performance Number
Answer: b) Risk Priority Number
Explanation: In risk management, RPN stands for Risk Priority Number. It’s a product of a risk’s severity, occurrence, and detection rating, and guide risk management efforts.
True or False: The probability of a risk is subjective and can vary depending on the perception of the risk manager.
- True
- False
Answer: True
Explanation: Probability is an estimated measure and varies based on available data and the perception of the risk manager. It isn’t a concrete or fixed value.
Which of the following is crucial to calculate risk priority?
- a) Identifying risks
- b) Analyzing risks
- c) Planning risk responses
- d) All of the above
Answer: d) All of the above
Explanation: All of these steps are critical in the process of calculating risk priority. Identification uncovers risks, analysis weighs them, and planning responses is an outcome of the prioritization process.
Risk weighting helps in determining:
- a) The most critical risks
- b) Least critical risks
- c) Both a and b
- d) None of the above
Answer: c) Both a and b
Explanation: Through risk weighting, a project manager can identify the most critical risks to address immediately and also the least critical risks, which can be monitored.
True or False: Calculating risk priority number (RPN) is a standard process for all types of risks.
- True
- False
Answer: False
Explanation: The calculation of RPN may not be suitable for all risk types as it largely depends on the nature of the risk and the contexts in which it arises. Different risks may require different methodologies for assigning priority.
