Agile burndown chart
ü
A burn-down chart is a graph with time plotted along the
horizontal axis and the quantity of remaining work tracked on the vertical axis.
ü
The quantity of remaining work is expressed in points, points on
the scale of the project. Per day or per week, a value is added.
ü
A line is drafted through all values, the burn-down. Almost
all agile projects use burn-down charts because of their predictive value.
ü
It is very simple to draw a trend line through all values in the
graph, especially in Excel. The moment in time where this trend line intersects
with the horizontal axis represents the expected completion date of the project
given the average speed of the team.
ü
If the speed is changing up or down, the intersection point
moves, resulting in a different expected completion date.
ü
For instance, due to optimizing the method. Or because new work
items are introduced. Or because work items become obsolete. When you use a burn-down
chart, the change’s effects become visible immediately.
