Within the counters, you can quickly see if an entity such as User Story, Feature, Bug etc. has any open relations to other items.
If there’s a Blocker relation or there are related Impediments, the relation number will be marked as having red background.
In the example below we can see that there are 3 Inbound Relations (one or more of which are Blockers or Impediments) and 1 Outbound Relation.
On the Relations tab it looks like it is shown on the picture below:
Only open relations matter. As soon as one of the related entities goes to the final state, the relation to it becomes greyed out in the Relations tab and hidden from a counter.
Customize Cards to add the Relations unit to cards of any size.
