We create some delivery based OKRs using Atlassian Goals. The easiest way to track and understand progress for these is based on count of completed Jira issues that need to get done to achieve the goal. E.g., if there are 10 Jira issues, and 8 are completed, i am 80% done. In general, is there a way to create a Progress Metric that can update systematically based on the work being tracked in Jira to achieve the Goal?
