We are already using Jira to visualize the work of ~30 people, and it's being rolled out to other teams too, so this number will increase dramatically.
One of the enhancements we need, is to be able to tag a ticket as blocked - and to be able to collect the blockers at the end of a month (or week, or whatever), and discuss them in a retrospective, for the purpose of spotting trends and solving blocker clusters.
The best way I've come up with, is to create a new issue type called "Blocker" and to log new blockers whenever needed. This lets me put as much detail as I want into the blocker, and it also lets me measure their lead & cycle time. There's a gaping hole with this approach though - how do I make the blocker look attached to the related project ticket?
Is there some other way I'm not thinking of? It would be ideal if we could put some kind of indicator on an issue in Jira-Agile, to highlight it as blocked.
