We use Jira to manage our software development projects. I have to generate a report that shows when a developer began work on the issue, when they completed work, when testing resources began testing, when an item has been moved back to failed, and when an item is fully completed and deployed. I see these changes in the Activity tab when viewing an issue, but I cannot find out how to add this data to a report or filter. I need to report on the date/times that the status and workflow changed. Any ideas?
