In addition to Jira's standard fields, you can use a set of free configurable traffic-light fields, now. They are globally available for all your issues.
...
An increasing set of samples, you'll find on the subpage "Sample Rules for automation".
Global Permissions
As admin: Optionally associate a customfield with a traffic-light field to set its option (customfield → traffic-light field → customfield)
Create a new custom field and give it the same name like the related traffic-light field in order to auto-associate them. The custom field must be of type "Text Field (single line)" or "Select List (single choice)". In the second case, create its options accordingly to the labels of your related traffic-light. Then put it on your screen associated to the issue operations for EDIT (see Atlassian's documentation on how to configure Jira's "Screen Scheme" and action "Associate an issue operation with a screen" if you are not familiar with that) but not on VIEW to avoid displaying that customfield in addition to the related traffic-light twice.
That auto-associated customfield will always represent the related traffic-light's label:
- you can use the associated customfield to set a traffic-light option by naming it's label (e.g. within Jira automation)
- you can use the associated customfield to represent the traffic-light's options (e.g. for exporting)
Set a traffic-light on the create-issue screen
Put your new customfield on your screen associated to the issue operations for CREATE in addition to EDIT. Setting the customfield value while creating a new issue, it will automatically synchronize/update the auto-associated traffic-light field while displaying that issue.
Update a traffic-light within a workflow post function
If you set the value of that customfield, e.g. by a workflow post function, it will automatically synchronize/update the auto-associated traffic-light field while displaying that issue.
As admin: configure colored trend arrows or other shapes instead of traffic-lights
