I want to query JIRA to see the assignees with the most re-opened JIRAs. The objective is to identify developers who may need additional training.
I would prefer to see this as a PERCENTAGE rather than a RAW number. For example, consider the case where Joe has resolved 100 JIRAs and had 20 get re-opened. Then there's Bill, who resolved only 30 JIRAs, but 15 them get re-opened. In this example, Joe has more re-opened JIRAs, but Bill is the one who needs more training. Joe has a rate of 20% re-opened, where Bill has 50%. It might be even better if I could limit this by date; for example looking at only the last 6 months of data.
One consideration is that a single JIRA may have multiple assignees overtime. I need to identify the single assignee who changed the status from In-progress to Resolved.
Thanks!
