    Por Que e Quando Desempenhar Esta Tarefa

    Risk Conditions are run against the change request based on their Order field from lowest to highest. The first Risk Condition that matches the change request record is applied. All subsequent risk conditions are then ignored whether they match or not. A risk calculation rule is defined with two elements.
    • Conditions that can evaluate to true or false. You can use a condition builder or write a script.
    • Risk and Impact field value settings when the conditions evaluate to true.

      ChoiceAction
      Condition Use the condition builder to add conditions. It is hidden if you selected Use advanced condition.
      Use advanced conditions Write the script in the Advanced condition field using standard business rule syntax. The condition must set the global variable answer to true or false.
      Use script values Write the script in the Script values field. Specify the Risk and Impact values in the script.

      The conditions are set using either the condition builder or an advanced condition script.
      In the following example, the Advanced condition script first determines whether the CI is a business service. If so, the script identifies whether the Business criticality value is 1 - most critical or 2 - somewhat critical. If it does, it sets the global variable answer to true.
      Critical business service risk condition

      When the Advanced condition script returns true, the script in the Script values field sets the change request Impact and Risk values based on the Business criticality value.
