These two type of charts are used to track the work in any project. A burn down chart shows how much work is remaining to be done while the burn up chart shows the progress in terms of the work completed and total amount of work. These charts are mostly used in Agile and scrum methodology. How the chart look like :
Burn Down Chart : A single line showing the work remaining in the project on each day. Vertical axis is amount of work and horizontal is time. It can be used to see the project velocity. We can compare the actual velocity against the velocity required to meet the deadline. We can calculate the exact percentage. The straight dotted line shows the ideal velocity of project. We can also see that when a team is ahead or behind the schedule.
There is a problem with the burn down chart that it is assumed that the amount of work should not change. So this chart doesn't shows realistic data where the additional workitems comes up or any workitem is removed to meet the dead lien. So a new chart Burn Up chart was introduced.
Burn Up Chart :
The dotted line shows ideal completion rate. The blue line shows the actual task completed and the red line shows the total task after addition or deletion of the tasks.
Here addition or deletion of any task can be depicted easily
Burn Down chart is ideal for those projects where amount of work is fixed but burn up can be used in any projects.
