A Risk Formula provides easeRisk for Jira with the information it needs to calculate risk fields based on mathematical expressions applied to other risk fields. For example, the field Risk Exposure could be calculated as the value of Risk Impact multiplied by Risk Probability, as explained in How to Configure Jira and easeRisk for Jira for Risk Management. A Risk Formula can be associated with one or more Risk Schemes.

Once a Risk Formula is associated with a Risk Scheme, the formula’s Target Field is automatically set as follows:

  • For all issues in the projects associated with the Risk Scheme where the issue type is a member of the formula’s Issue Types option.

  • Whenever the value of a field used in the Formula option changes.

To manage risk formulas:

  • Go to Jira navigation > Risks > Formulas under Administration.
