You can define risk calculation rules on which the risk and impact of a change are calculated. Change Management - Change Risk Calculator is activated by default in the base system.

## Before you begin

Role required: itil_admin or admin

## About this task

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 <var class="keyword varname">true</var> or <var class="keyword varname">false</var>. You can use a condition builder or write a script.
* Risk and Impact field value settings when the conditions evaluate to true.

## Procedure

1. Navigate to AllChangeAdministrationRisk Conditions.
2. Click New, or click the risk condition to modify.  
   You can also edit risk conditions from within the Change Request form by opening the form context menu and clicking Edit Risk Conditions.
3. Complete or update the form, as appropriate.  
   {#define-risk-and-impact-conditions__table_xym_4zl_wy__entry__2}

   | Field | Description |
   |:-|:-|
   | Name | Enter a descriptive name for the rule |
   | Risk Impact | Select a value for one of these fields. The selection determines which field to update based on this risk calculation. |
   | Active | Select the check box to use the rule. |
   | Order | Enter the order in which this risk calculation is evaluated. Rules with lower numbers are evaluated first. If there are two or more rules with differing orders, the rule with the lowest order is evaluated and the others are ignored. |
   | Use advanced condition | Select the check box to enter a script instead of using the condition builder. |
   | Use script values | Select the check box to hide the Risk and Impact fields. The script specifies the risk and impact values. |
   | Description | Enter a description of how this risk calculation is applied. |

   {#define-risk-and-impact-conditions__table_xym_4zl_wy}  
   Important:  
   If the Calculated risk value doesn't update, check the following:
   * The rule's Active check box is selected.
   * No rule with a lower Order value matched the change request first. The first matching rule wins, and the system ignores later rules.
   * If Use script values is selected, the script assigns both the Risk and Impact values.
   {#define-risk-and-impact-conditions__ul_jzn_ds3_tjc}
4. Specify the rule based on your selected rule method.

   | Choice | Action |
   | Condition | Use the condition builder to add conditions. Do not use the Keywords field as a filter condition. Risk and impact values are not calculated for keywords. To achieve equivalent filtering, use the Use advanced condition option and write a script that performs the text comparison explicitly. Note: The Condition section 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 <var class="keyword varname">true</var> or <var class="keyword varname">false</var>. |
   | 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. |

   {#define-risk-and-impact-conditions__choicetable_zdq_xvm_lz}  
   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 <var class="keyword varname">true</var>.  

   When the Advanced condition script returns
   <var class="keyword varname">true</var>, the script in the Script values field sets the change request
   Impact and Risk values
   based on the Business criticality
   value.
