Burn up and Burn down chart

Postby soniaacp_123 Mon May 30, 2016 4:43 pm

Can any one tell what does this means related to Burn up chart -
"we do have target line to represent the total size."

Also, what does this means related to Burn down chart -
Top of the bar will be lowered when work is delivered.

Hello,

In the burn up chart (in slide 11) the target line was 100, but during iteration 6, 20 more story point were added and the target line became 120 story point and that is the target story point that we have to complete for the project.

The Top of the bar will be lowered when work is delivered in the Burn down Bar Chart NOT in Burn down chart. The total bar length represent the story point for release. So once any work is completed during iteration, that means any story point is completed during the iteration then the bar is lowered to show the remaining story point remaining.

Please let me know if it make sense.

Cheers,
Bhabani

burn up chart = this chart shows how much work is completed so far.
this chart usually has target line that represent total size.
this graph usually has linear progress.
the goal is to go up linearly and meet with target line.
also, if their is any addition/deletion of scope - this chart can display such changes very well.

burn down chart = this chart shows how much work is [not done] pending at given point in time .
It is a simple graph showing amount of work on a vertical and timeline on a horizontal axis.
As time progresses we keep track how much work is still not done.
The goal is to hit the ground. The steepness of the curve can help us approximate when it’s going to happen or, in other words, when we’re going to be done with the whole work.
if their is any addition/deletion of scope - its difficult to display such changes.

refer this - just incase if you wish to know which one is better

burn down bar chart = this chart shows how much work is [not done] pending at given point in time .
It is a simple bar graph showing amount of work on a vertical and timeline on a horizontal axis.
As time progresses we keep track how much work is still not done.
please note = every time we deliver some points - Top of the bar will be lowered when work is delivered..
if their is increase in scope = the bottom of the bar will be lowered down - it may come down beyond x axis.
if their is any deletion of scope - the bottom of the bar is raised.

this one is pretty tricky.
i think this link will help

This is informative. Thank you.
I have one question wherein what should be done when we started a release with some assumptions and estimate only few stories in the product backlog. How do we represent the graph in the cases where the story points are estimated in the progressive elaboration manner?

Dear Durga,

This is where your burn up chart come into pictute. When more story points are added to the producut back log then value in the Y axix are bumped up as shown in the picture and the same way if story points are moved the Y axix is adjusted accordingly.

Cheers,
Bhabani
