In Agile, the Definition of Done (DoD) typically requires that the feature be both developed and fully integrated into the release package before it is considered complete. Even though the feature was successfully tested and demonstrated by QA, if it is not included in the release package, it is not technically completed according to the DoD. Therefore, its story points should not be added to the burndown chart until it is actually part of the release. This ensures that the team's progress is accurately tracked based on completed, released work.
