A Scrum team can learn a lot form sprint burn-down charts. I want to help you recognize typical patterns, understand what causes problems and how to resolve these issues. For continuous improvement in Scrum you need to be able to read the patterns in your burn-down charts.
The burn-down chart is a tool in the agile Scrum framework to unearth inefficiencies in a team and improve towards greater agility. In an agile team or organization you should know about this chart and how to construct it.
