Once your iteration is underway, Dependency Map makes it simple to track progress.
This example shows the Epics and Stories in an ongoing Sprint. The issue icons denote the Issue Type and the colors represent Priority.
There are two types of arrows: the dashed black arrows is the Epic-to-Story breakdown, and the red arrows are the dependencies.
When you select an issue that is at risk, any related issues become highlighted too. This makes it easy to see the impact of potential delays.
