In Risk Management, risk weighting and priority calculation are crucial according to the guide provided by Project Management Institute’s Risk Management Professional Certification (PMI-RMP). The objective of this certification is to equip professionals with necessary skills and knowledge to identify and manage potential risks in an efficient manner.
1. PERFORMING RISK WEIGHTING
Risk weighting is all about assessing the relative importance of various risks based on their potential impact and the possibility of their occurrence.
To carry out risk weighting, professionals generally use a tool known as a Risk Matrix. This is a grid with severity (impact) along one axis and probability (likelihood) on the other. Risks are then placed on this grid providing a clear visualization of the importance of each risk relative to others.
If we consider a project that has the potential risks as follows:
- A: Supplier delay (Medium impact, high probability)
- B: System failure (High impact, low probability)
- C: Budget overrun (High impact, Medium probability)
If we allocate numbers to the categories (For example, 1 to 3 for Low to High), a matrix similar to this could be produced:
| Low Impact | Medium Impact | High Impact | |
|---|---|---|---|
| High Likelihood | A | C | |
| Medium Likelihood | |||
| Low Likelihood | B |
From this matrix, we can clearly see that risks with high likelihood and high impact like risk C are the most heavily weighted, while those with low in both categories are the least weighted.
2. CALCULATING RISK PRIORITY
After risks have been weighted, we proceed to calculate risk priority. Risk priority is an essential tool for project managers to decide where to allocate their efforts and resources.
Risk priority is calculated by multiplying the risk’s probability by its impact. The result of this multiplication is then used to guide risk response planning.
So again, if we consider the same example:
| Risk | Impact Score | Likelihood Score | Priority Score (Impact*Likelihood) |
|---|---|---|---|
| A | 2 (medium) | 3 (high) | 6 |
| B | 3 (high) | 1 (low) | 3 |
| C | 3 (high) | 2 (medium) | 6 |
The highest score here represents the highest risk priority.
This way, through risk weighting and risk priority calculation, a project manager is not only able to identify potential risks but can also quantify their severity. This further aids in effective risk response planning. It is important to remember that the ultimate goal of risk management is not to completely avoid all risks, but rather to prepare for risks that are most likely to occur and can have the most significant potential impacts. This practical approach is what the PMI-RMP certification aims to instill in professionals.
Practice Test
True/False: Risk weighting is the process of quantifying and ranking potential losses from individual risks.
- True
- False
Answer: True
Explanation: Risk weighting is a method used to identify and prioritize the potential impact of different risks based on their severity.
Which of the following are components of risk weighting? (Multiple select)
- a) Probability of occurrence
- b) Severity of impact
- c) Level of uncontrollability
- d) Frequency of occurrence
Answer: a,b,c,d
Explanation: All of these are key factors in risk weighting. A risk is more significant if it is likely to happen often, if it would have a serious impact, and if it cannot be controlled effectively.
True/False: A risk with a high priority should be mitigated first.
- True
- False
Answer: True
Explanation: In risk management, risks that have a higher priority are usually addressed first because they have the potential for the greatest negative impact on the project or organization.
What is meant by ‘Risk Priority’?
- a) A characteristic attribute of risk
- b) The combination of probability and severity of a risk
- c) The order in which risks should be addressed
- d) The final step in risk management
Answer: c
Explanation: ‘Risk Priority’ is the term for the order in which risks should be addressed. It’s the result of risk analysis and allows organizations to focus on the most significant risks first.
Which of the following is not a factor contributing to risk priority?
- a) Risk mitigation cost
- b) Risk frequency
- c) Risk acceptance
- d) Risk severity
Answer: c
Explanation: Risk acceptance is a response strategy, but it does not factor into determining risk priority. Factors that contribute to risk priority include the frequency, severity of the risk and mitigation cost.
True/False: To calculate the risk priority, you need to multiply the risk probability by the risk impact.
- True
- False
Answer: True
Explanation: This method of risk prioritization is commonly known as risk scoring or risk rating. It’s based on the principle that a risk’s priority is proportional to its potential impact and the likelihood of its occurrence.
How does risk weighting aid in decision-making?
- a) It reduces the decision-making process time
- b) It identifies which risks should be addressed first
- c) It estimates the cost of each risk
- d) All of the above
Answer: b
Explanation: Risk weighting is used to identify and prioritize the potential impact of different risks allowing decision-makers to focus on the most potentially harmful ones first.
The risk management process is not complete without calculating the risk ________.
- a) priority
- b) probability
- c) impact
- d) mitigation
Answer: a
Explanation: After identifying, assessing and prioritizing risks based on their weight, the risk priority is calculated. This helps in determining the order in which risks should be addressed.
Risk weighting is the same as risk assessment.
- a) True
- b) False
Answer: b
Explanation: Risk weighting is a part of risk assessment and not the same. It focuses on ranking potential risks based on their severity thus helping prioritizing risk responses.
Risk priority is determined only after all risks have been identified and assessed.
- a) True
- b) False
Answer: a
Explanation: Risk priority calculation is a step in risk assessment process which takes place only after all potential risks have been identified and their impact assessed.
Larger the calculated risk priority, ___________ it should be addressed.
- a) later
- b) sooner
- c) less frequently
- d) more frequently
Answer: b
Explanation: A higher risk priority value indicates a larger potential impact or frequency, so those risks should be addressed more quickly.
All risks with the same risk priority should be handled at the same time.
- a) True
- b) False
Answer: b
Explanation: While risks with the same priority have similar levels of impact, they can still differ in factors such as complexity, required resources and dependencies. Thus, it may not always be practical to handle them simultaneously.
Interview Questions
What is the primary goal of risk weighting in project management?
The primary goal is to prioritize the identified risks in a project according to their significance and possible impact on the project.
What factors should be taken into account when performing risk weighting?
The factors include risk probability, risk impact, and risk urgency.
What does a high risk-priority number (RPN) indicate in project risk management?
A high risk-priority number (RPN) indicates that the risk has a higher level of seriousness. It means that the risk could have a significant impact on the project, is highly likely to occur, or is urgent to address.
How is risk probability assessed during risk analysis?
Risk probability is assessed by estimating the likelihood of a risk occurring during the project’s lifecycle. This can be done using data from past similar projects, expert judgments, or risk probability assessment tools.
How can risk impact be measured?
The impact of a risk can be measured in terms of its potential effect on the project’s objectives like scope, cost, time, or quality. For instance, the impact can be described on a scale of low, medium, and high.
In risk weighting, why is it important to consider risk urgency?
Risk urgency is important as it determines the speed at which a response to a risk is required. Risks requiring rapid responses should be given a higher priority than those that can be dealt with later.
How is Risk Priority Number (RPN) calculated?
The RPN can be calculated by multiplying the scores of risk severity, occurrence, and detection. This method is often used in the Failure Mode and Effects Analysis (FMEA) technique.
How should risks with almost identical risk priority numbers be handled during risk weighting?
While these risks have numerically equivalent RPNs, the project team should understand the individual components (probability, impact, and detectability) of each risk to determine the best response approach.
What is the role of the Risk Register in risk weighting and prioritization?
The Risk Register records all identified risks, including their descriptions, probability, impact, responses, and assigned risk owners. It is also where the calculated RPNs are documented, serving as a key tool for risk weighting and prioritization.
Can the order of risk priorities change during a project’s lifecycle?
Yes, the risk priorities can change as the project progresses. Continuous risk assessment and reassessment help in discovering changes in risk factors and revising the risk priority accordingly.
What is the advantage of assigning numerical scores to risks while performing risk weighting?
Numerical scoring provides an objective and quantifiable measurement for risk prioritization. It allows for easier comparison and more effective communication of risk severity levels among the project team.
What is a weighted-score risk matrix?
A weighted-score risk matrix is a tool used to visualize and prioritize risks based on their weighted scores, enabling better decision-making about which risks to focus on.
What is the need for risk revision and auditing while performing risk weighting?
Risk revision and auditing ensure that the risk weighting process is being carried out effectively and efficiently. They help in identifying any changes in risk factors or in the effectiveness of the implemented risk responses, modifying the risk priority list if necessary.
What is the benefit of using a quantitative analysis in risk weighting?
Quantitative analysis helps to assign numerical values to risks, providing a more objective way to prioritize risks. It helps in distinguishing between high and low priority risks, and guides decision-making on risk response.
How does risk weighting help in the allocation of resources in a project?
By prioritizing risks, risk weighting helps project managers to efficiently allocate resources to address the highest priority risks, avoiding wasting resources on lower-priority risks.
