A common set of questions that come up from our many Atlassian customers are related to what happens in the life of a sprint and what else is affected. I suggest creating a page in the documentation to answer these questions in one place together. The list of questions below are what people ask me.

Create Sprint

How are issues with no estimate shown in the Backlog panel?

Why are estimates on sub-tasks not included in the Backlog panel?

Start Sprint

What happens to issues that are added to the sprint after the sprint is started?

They are shown as a Scope Change in the Reports. Their estimates are not included in the reports.

What happens to issues whose estimate is changed after the sprint is started?

A snapshot of the issues in the sprint is taken to be used for the Sprint Report and Velocity Report. So changes to estimates do not appear in the reports.

Which reports show scope creep and how are those numbers calculated exactly?

Close Sprint

Can I add an issue to a Closed sprint?

Can I remove an issue from a Closed sprint?

Can I modify an issue's estimate after a sprint has been closed? Which reports are affected and which are not affected?
