Summary

Automation For Jira's official documentation about Smart Values - Conditional Logic explains how to execute an action if an condition is verified. However, it does not explain how to:

• execute an action if the condition fails (=ELSE condition)
• execute an action in case of multiple IF/ELSE conditions

The purpose of this article is to explain how to write a rule using Smart Values to implement a complex conditional logic which has multiple IF/ELSE conditions.

Environment

• Jira Data Center Only (not applicable to Server licenses)
• Applicable Jira / A4J (Automation for Jira) versions which include the Create Variable action:
  • Jira 9.11.0 and any higher version (this Jira version ships with A4J 9.0.1)
  • OR Jira 8.20.0 and any higher version, in combination with A4J 9.0.1 or any higher version

Solution

Use Case

The use case of this rule is the following:

• A Jira project has 2 Select List (single option) fields that are related to Vulnerabiliies:
  • The field Impact of Vulnerability which has the possible options below:
    • Critical
    • High
    • Medium
    • Low
  • The field Vulnerability Likelihood which has the possible options below:
    
    • High
    • Medium
    • Low
• This project also has Number field called Risk score, which will be calculated based on the logic below:
  • The Impact of Vulnerability field needs to be converted into a number as follows
    • Critical → 20
    • High → 15
    • Medium → 10
    • Low → 5
  • The Vulnerability Likelihood field needs to be converted into a number as follows:
    • High → 15
    • Medium → 10
    • Low → 5

  • The Risk score field needs to be calculated as the sum of the 2 numbers above:

    Risk Score = Numerical value of "Impact of Vulnerability" + Numerical valuer of "Vulnerability Likelihood"

Preliminary steps - Get the Custom Field IDs

Before configuring the automation rule, you need to first identify the ID of the 2 Select List custom fields, since this ID will be different depending on the Jira environment:

• Go to ⚙ > Issues > Custom Fields
  • Search for the Vulnerability Likelihood custom field, and click on ... > View
  • Get the ID from the URL: it is custom field ID that is needed to configure the automation rule
• Repeat the same steps for the other field Impact of Vulnerability

Rule configuration

The automation rule will be configured like this:

New Trigger: "Field Value Changed"

• Fields to monitor for changes: select the 2 Select List custom fields Impact of Vulnerability and Vulnerability Likelihood

New condition: "Issue fields condition"

• Field: "Impact of Vulnerability"
• Condition: Is not empty

New condition: "Issue fields condition" 

• Field: "Vulnerability Likelihood"
• Condition: Is not empty

New action: "Create Variable"

• Variable Name: impact

• Smart Value:   make sure to replace XXXXX with the Custom Field ID of the field Impact of Vulnerability
  

  {{if(equals(issue.customfield_XXXXX.value, "Critical"), "20", if(equals(issue.customfield_XXXXX.value, "High"), "15", if(equals(issue.customfield_XXXXX.value, "Medium"), "10", if(equals(issue.customfield_XXXXX.value, "Low"), "5"))))}}

New action: "Create Variable"

• Variable Name: likelihood

• Smart Value:   make sure to replace XXXXX with the Custom Field ID of the field Vulnerability Likelihood

  {{if(equals(issue.customfield_XXXXX.value, "High"), "15", if(equals(issue.customfield_XXXXX.value, "Medium"), "10", if(equals(issue.customfield_XXXXX.value, "Low"), "5")))}}

New action: "Edit Issue"

• Choose fields to set...:
  • Select the field Risk Score

  • Copy the expression below:

    {{#=}}{{impact}} + {{likelihood}}{{/}}
