Customers use different naming conventions for incident severity. It would be good to allow customisation of the severity levels to match customers' existing naming conventions.

For example, many other tools use a priority scale like P0-P4.

Atlassian status - 22 October 2019

Given the interest level here, it is on our short term roadmap to add severity level customization to Jira Ops. No ETA yet - we'll share more once we scope this out in the next week or two.

If you're interested in a brief chat about your requirements here (or anything else re Jira Ops), please drop us a note at jira-ops-feedback@atlassian.com. Thanks!
