## 8.9 Burndown Charts
Burndown charts are visual tools used to track different dimensions of progress in an Agile project. These charts show how a planned and measurable item (e.g. effort hours or story points) is being ‘burnt down’ to zero (no work left).
- Burndown charts track the progress of iterations (effort hours or story points across days) and the progress of releases (story points across iterations), highlighting any obstacles that might hinder the team’s performance.
- Burndown charts are dynamic, in the sense that the planned work may change as a result of the feedback received during development.
- Burndown charts should be highly visible, enabling Project Core Team (PCT) members and the broader project organisation to see the current progress and forecast with complete transparency.
