About Risk Scores

Risk scores are a calculated parameter that equals probability multiplied by impact. Risk probability, impacts and scores are calculated before and after risk mitigation. Risk score is calculated for each risk category as well as all risk categories.

Original, Pre-, and Post-Mitigation Probabilities, Impacts and Scores

RiskyProject calculates three sets of probabilities, impacts and scores for each risk category as well as combined for all categories. You can view these sets in the Risk Register, Mitigation Assignment View, and Mitigation tab of Risk Information Dialog:

• Pre-Mitigation: reflects most recent changes to probability and impact for each category. If you use qualitative analysis, the current probabilities and impacts are editable in the Risk Register. You can also edit them in the Risk Form or the Probabilities and Outcomes tab of the Risk Information dialog box. For quantitative analysis (with project schedule) current set of probability, impact, and scores is calculated based on risk assignments to task or resources. Current set of probability, impact, and score is shown as a first line on Mitigation Tab on Risk Information dialog box.
• Post-Mitigation: Post-mitigation probability, impact and score reflect changes to risks due to mitigation plans. Multiple mitigation plans can be assigned to one risk. They are editable in the Assign Mitigation view and in Mitigation tab of the Risk Information dialog box. In the Risk Register you can show the latest read-only probability, impact and score, which corresponds to the last line in Mitigation tab.

In the Assign Mitigation view, in addition to editing the post-mitigation probabilities, impacts and scores for all categories, you can also edit values for individual categories, such as cost, duration, quality, technology, etc. Probabilities, impacts and scores for individual categories are not used to calculate combined probabilities, impacts and scores, which should be entered independently. In addition, in this view you can enter both predicted and actual probabilities, impacts and scores.

Post-mitigation probabilities, impacts and scores are not affected by quantitative analysis.

You can view all sets of probabilities, impacts, and scores in the Risk Register.
