For example, a scale range of 100 values will add complication without adding accuracy to your risk management work. However, be aware that a bigger scale does not equate to more accuracy. The more intervals used, the more specific the valuation of risk. A risk matrix is usually a 3 x3, 4×4, or 5×5 grid to easily fit on one page and convey the core information visually. For example, there cannot be three intervals for probability (X-axis) and five for impact (Y-axis). In the probability and impact matrix, both metrics must have the same number of intervals for calculations and valid assessment to be possible. insignificant, minor, moderate, major, significant.Impact axis label: impact, consequence, possible consequence, or severity.The Y-axis should be labeled to include the rating scale. highly improbable, improbable, unlikely, probable, highly probable.Probability axis label: probability, likelihood, or likelihood of occurrence.The X-axis should be labeled appropriately to include the scale of values. Any risk matrix should reflect these elements: Probability (or Likelihood) on X-Axis indicators across the matrix of risk scores to signal the level of significanceĬompanies with formalized risk assessments have risk matrix templates to reflect their project types or industry.axis for impact, values from low to high.axis for probability, values from low to high.The risk matrix is also called a probability and impact matrix because the two axes must be probability and impact, even if different words are used. Like the definitions, the value range for probability and impact is tailored to the specific project’s scope. Probability and impact definitions and the corresponding values for each should be determined early in the project and consistent throughout the project. The value scale for probability and impact is also tailored to the specific project within the early risk assessment work. For all risk assessments, the quality of the data used directly correlates to the effectiveness of the resulting project decisions. The definitions of probability and impact levels are determined as part of the initial risk assessment. Or vice versa, a risk is most unlikely to occur (low probability), but the project will suffer (high impact) if it does happen. Probability and impact are used in conjunction because you can have a risk that will most certainly happen (high probability) but with little measurable change for the project (low impact). Risk impact refers to the level of disturbance to the project if a risk occurs. Risk probability is the likelihood of occurrence or what are the chances of that risk happening within the time frame of the project. After the perform qualitative risk analysis process, each risk’s probability and impact are documented in the risk matrix tool. The risk matrix tool fits within the overall risk management knowledge area, specifically the early risk processes. Project managers should complete a risk matrix as part of the perform qualitative risk analysis process. The risk matrix’s visual depiction conveys the project’s risks, so the project manager and team are better positioned to determine risk mitigation and response strategies. Risk Matrix advantages and disadvantages.The term “risk matrix” or “risk matrix PMP” will be used for simplicity.

Students should know PMI’s Project Management Professional (PMP)® exam uses the term “probability and impact matrix.” However, some project managers informally call it the: risk control matrix, risk matrix, PMP risk matrix, risk matrix PMP, or probability and impact matrix PMP. Students preparing for Project Management Institute (PMI) exams and project managers refining their skills should know what a risk matrix is and how it benefits the project. The risk matrix tool communicates the overall project risks and supplies information, increasing the effectiveness of a risk response. Within the perform qualitative risk assessment process, each identified risk’s probability and impact score is mapped within the risk matrix tool to help the Project Manager and team better understand how certain risks may impact the project.
