Burndown Charts

What is Burndown Chart in Scrum?
A burn down chart is a graphical representation of work left to do versus time. It is often used in agile software development methodologies such as Scrum. However, burn down charts can be applied to any project containing measurable progress over time.

Typically, in a burn down chart, the outstanding work is often on the vertical axis, with time along the horizontal. 

It is useful for predicting when all of the work will be completed. In the Daily Scrum, the Development Team updates the Sprint Burn Down and plots the remaining work of the day. A burndown chart is almost a “must” have tool for a Scrum team for the following main reasons:

   1. monitoring the project scope creep   2
. Keeping the team running on schedule   
3. Comparing the planned work against the team progression



How to Create a Burndown Chart?
To create this graph, determine how much work remains by summing the Sprint Backlog estimates every day of the Sprint. The amount of work remaining for a Sprint is the sum of the work remaining for the whole Sprint Backlog. Keep track of these sums by day and use them to create a graph that shows the work remaining over time.
