The Sequential Index column displays a hierarchical number corresponding to an item's position within the structure.
The first number in the index represents the top level of the hierarchy, the next number (after the period) refers to the second level, etc. To better understand how this works, let's look at the above example:
- Epic 1 has a sequential index of 1, because it is the first item in the top level of the hierarchy.
- Story 2 has a sequential index of 1.2, because it is the second child under Epic 1.
- Bug 1 has a sequential index of 1.2.1, because it is the first child under Story 2.
- Task has a sequential index of 2.1.1, because Epic 2 is second item in top level, Story 4 is the first item beneath it, and Task is the first child beneath that.
