Quantitative risk analysis is essential in safeguarding your projects and ensuring that they are delivered successfully. Therefore there is a need to both assess AND prioritize risk. Time would be better spent managing those risks that would cause more significant concern. For example, there may be little reason to spend significant time managing a risk that has only a small likelihood of turning into an issue especially if it only has trivial levels of impact. Most projects find themselves faced with a variety of risks that must be balanced against the resources available. Risk management within these (and all) projects, requires careful consideration and effort with a key focus on being able to assess and prioritize risks, so they receive an appropriate level of attention. Your company, like many others, will no doubt undertake a variety of projects. Why you need need a Qualitative and Quantitive Assesment of Risk The Probability Impact Matrix is a simple tool that utilizes a combination of impact and probability variables to help in both categorizing and determining the priority of specific risks. In this article, we are going to take a look at a tool usually used in the analysis and control of risk, the Probability Impact Matrix. Reference: Garvey, Paul R., "Implementing a Risk Management Process for a Large Scale Information System Upgrade - A Case Study", INCOSE Insight, May 2001, p.5.Analysing Risk is a key step in any risk management process The above table does not assign a categorical rating (i.e., High, Medium, or Low) to a risk event that is certain to occur. In this case, we say the event is no longer a risk on the IS upgrade, it is considered an issue that presently exists on the project. A risk event that is certain to occur has, by definition, probability equal to one. The table above does not assign a categorical rating (i.e., High, Medium, or Low) to a risk event that is certain not to occur. In this case, we say the risk event does not exist. When we assess the probability a risk may occur, we are technically assessing a conditional probability that is,Ġ 0 - 0.05 - 0.15 - 0.25 - 0.35 - 0.45 - 0.55 - 0.65 - 0.75 - 0.85 - 0.95 - < 1Ī risk event that is certain not to occur has, by definition, probability equal to zero. The associated risk event represents a future event that may occur.

Unlikely - Can assume will not occur in career/equipment service life. Remote chance of occurrence expected to occur sometime in inventory service life
