How can I show blockers?

[Mark Crosley]

How do I show (on a card) that an issue is a blocker or is blocked? Displaying linked issues isn't helpful, since there are many kinds of links, and the majority aren't blockers.

We have used the Flag on Stories / Tasks to show when they are blocked. The problem we've run into with this is that it's granualr but doesn't show at a high level project-level blockers.

A plugin that displays dependencies (specifically the "is blocked by" issue links) directly on the Backlog view of the Scrum board is Dependency Risk for JIRA.   I know it doesn't (yet) display anything directly on the card, but does the plugin help with your need to show blockers?

A solution is to use a plugin : JQL Tricks Plugin
In your board Configuration -> Card Colors -> Colors based on queries -> Use JQL filter with JQL Tricks Plugin
