Impact Assessment is the evaluation of the impact of a risk if it were to occur. If the risk would to occur would it be catastrophic to the project or a minor inconvenience? An impact assessment is generally conducted in meetings or in interviews with individuals who have the appropriate knowledge to evaluate the impact of a risk. Upon completion of an impact assessment a risk is often given an impact score such as high = 3, medium = 2, or low = 1.
What is impact versus probability?
Impact and probability are the two main components of Risk analysis. Looking at impact versus probability is common in order to categorize and prioritize risks as some risks may have a severe impact on projects objectives but only happen on rare occasions, while other have a moderate impact but occur more frequently.
What is risk probability?
Risk probability, or likelihood, is the possibility of a risk event occurring. The likelihood can be expressed in both a qualitative and quantitative manner. When discussing probability in a qualitative manner, terms such as frequent, possible, rare etc. are used.
What is the probability matrix?
The Probability and Impact Matrix is one the most commonly used qualitative assessment method . It is based on the two components of risk, probability of occurrence and the impact on objective(s) if it occurs. The matrix is a two-dimensional grid that maps the likelihood of the risks occurrence and their effect on the project objectives [5]. The risk score, often referred to as risk levelor the degree of risk, is calculated by multiplying the two axes of the matrix.
What is the impact of probability assessment?
The probability assessment involves estimating the likelihood of a risk occurring. The impact assessment estimates the effects of a risk event on a project objective. These impacts can be both positive and negative; i.e., opportunities and threats.
What is qualitative risk assessment?
Qualitative methods for risk assessment are relatively rapid in practice, cost effective and easily understood . The results from the qualitative assessments are not an accurate estimate of risk. However, they provide a rather descriptive result and often with sufficient information for planning responses. The results from these assessments also set the foundation for more detailed quantitative analysis, if possible and warranted. It is performed regularly throughout a projects life cycle as new risks may emerge at later stages as well as a risk response may result in other risk events . Classifying the risks enables organizations to reduce uncertainty levels and focus primarily on the high-risk events. There are two qualitative methods of assessing risk events in terms of impact and probability, both involving rating the impact and probability. These are Risk Probability and Impact Assessment and Probability and Impact matrix .
What is risk management?
Risk management is a four-stage process. The first being identification of risks, second analysis (assessment), then the risk response and finally the risk monitoring . In risk analysis, risk can be defined as a function of impact and probability . In the analysis stage, the risks identified during the Risk Identification Process can be prioritized from the determined probability and impact of the risk event, using qualitative or quantitative methods. Other factors, such as the response time-frame and the tolerance should be taken into account when analyzing and categorizing the risks .
What is risk analysis?
The risk analysis is a two-stage assessment process. Initially, qualitative methods are used to examine, categorize and determine the main risk events identified, which are relevant for a more detailed quantitative assessment. In risk analysis, risk is traditionally defined as a function of probability and impact .
What is risk probability and impact?
The concept of Risk Probability and Impact is the fundamental building block on which Project Risk Management is raised. In this article, we will try to understand what is risk probability and what is risk impact.

What does it mean when the probability is 100%?
If the risk probability value is 100%, then it is certain to occur; and as such, it defeats the definition of risk, an uncertain event or condition that may or may not occur. It cannot also be 0% for the same reason, as it means it is certain not to occur. You may also be interested in: Probability and Impact Matrix.
What is the greater the risk?
The more likely or severe an event, the greater the risk.
What is risk measurement?
Risk measurement - A process to determine the likelihood of an adverse event or threat occurring and the potential impact of such an event on the institution. The result of risk measurement leads to the prioritization of potential risks based on severity and likelihood of occurrence.
How to calculate residual risk?
The formula for residual risk is: Residual risk = Inherent risk * Control effectiveness. Residual risk is greatest when the inherent risk is high and the controls for mitigating the risk aren’t effective. It decreases when controls are effective.
What is an inherent risk score?
Inherent risk scores represent the level of risk an institution would face if there weren’t controls to mitigate it. For example, think of the risk of a cyberattack if the institution didn’t have any defenses in place.
What is residual risk?
Residual risk is the risk that remains after controls are taken into account. In the case of a cyber breach, it’s the risk that remains after considering deterrence measures. This score helps the organization review its risk tolerance against its strategic objectives.
Why do risk assessments require a lot of specific thought and analysis?
If risk assessments seem like they require a lot of specific thought and analysis, that’s because they do. The goal is to remove as much subjectivity from the process as possible and create quantifiable metrics.
What is risk analysis?
Risk analysis - The process of identifying risks, determining their probability and impact, and identifying areas needing safeguards. Risk assessment - A prioritization of potential business disruptions based on severity and likelihood of occurrence.
What is a probability matrix?
What is a Probability and Impact Matrix? Well, it’s part of your qualitative risk analysis. It’s a grid for mapping the probability of each risk occurrence, and its impact on your project objectives if that risk occurs.
Why do we use numbers in probability?
The reason we use numbers is if numbers are used they can be multiplied to give a probability impact score for each risk, and that’s a great way to prioritize those risks. Here’s an example of a probability of impact Matrix.
What is the probability of project risk?
The first problem in assessing the probability of project risks is the term itself. “Probability” has a precise statistical meaning, for example “a measure of the relative frequency or likelihood of occurrence of an event, whose values lie between zero (impossibility) and one (certainty), derived from a theoretical distribution or from observations” (Collins 1979). However, its general usage is less clear, including its use within the risk management process. Confusion has also arisen as a result of the use of alternative terms in risk guidelines to describe the uncertainty dimension, such as “frequency”, “likelihood” or “chance”, giving the impression that these are mere synonyms for “probability” when, in fact, they are distinctly different. If the uncertainty dimension of risks is to be properly assessed and described, using the term “probability”, it is essential that assessors understand what they are trying to assess.
What are the dimensions of probability and impact?
It is common to use the terms “probability” and “impact” to describe these two dimensions, with “probability” addressing how likely the risk event or condition is to occur (the uncertainty dimension), and “impact” detailing the extent of what would happen if the risk materialised (the effect dimension). When assessing the significance of any given risk, it is necessary to consider both dimensions. Clearly an uncertain event which is likely to occur (i.e. it has high probability) but which would have little or no effect on objectives (low impact) is not significant. Similarly a risk may have such a low probability that it might not be worth considering even if some significant impact were theoretically possible. Risk management processes often include frameworks for determining the significance of a risk based on both probability and impact, such as the two-dimensional Probability-Impact Matrix (Project Management Institute 2000, 137).
Why is risk probability assessment important?
Proper assessment of risk probability is however critical to the effectiveness of the risk process, for the following reasons: If risk probability assessment is faulty, the accuracy of risk prioritisation will be affected, leading to a potential failure to focus on the most significant risks.
How to assess risk probability?
A number of techniques have been developed to assist in assessment of risk probability by providing values against which the likelihood of the risk occurring can be compared, asking whether the probability of the risk occurring is more, or less, or the same as the value being presented. The aim of all these techniques is to adjust the comparator until the assessor cannot distinguish between the risk probability and the value being presented. This value is then taken as the best estimate of the risk probability. There are different ways of presenting probabilities against which risk probability can be compared. These include:
What is the term for the possibility of a risk being close to a certain point in time?
Proximity. If the possible occurrence of a risk is close in time or space to those assessing its probability, it will be seen as more likely than risks which might occur later in time or further away in space.
What is project risk?
This is particularly true of project risks, those uncertain events or conditions which if they occurred, would affect project objectives. Since the objectives of a given project are likely to be different from those of previous projects, the risks affecting a new project are also likely to be different.
How to manage sources of bias?
A two-step approach is recommended for managing sources of bias when estimating uncertain situations, including assessment of risk probability. This first requires awareness of the issues, understanding sources of bias, whether they originate from perceptual factors or heuristics. Not only must these be understood in theory, but their operation in practice must be identified, drawing on previous experience wherever possible. This diagnosis allows the second step to be taken, namely action. Understanding one's preferred approach to uncertainty can open the door to managing it, reducing or removing sources of bias at both individual and group levels (Hillson & Murray-Webster, 2004).
