You were asked to take a few minutes to glance over the burn-down graph below and describe<br />

what you think the different parts <strong>of</strong> the graph are for and how it is one <strong>of</strong> the key tools for<br />

monitoring your s<strong>of</strong>tware development progress and ensuring that you deliver on time.<br />

Burn Down<br />

Each unit is a day <strong>of</strong> work<br />

left on your user stories,<br />

starting at the total days<br />

at the top and decreasing<br />

to 0 days at the bottom.<br />

What do you think would<br />

be measured on this<br />

graph, and how?<br />

This graph monitors how quickly you and<br />

your team are completing your work,<br />

measured in days on the vertical axis.<br />

This chart then plots how quickly you<br />

tick <strong>of</strong>f your work remaining against the<br />

number <strong>of</strong> days left in your iteration.<br />

Days left<br />

You’ll plot your work against<br />

the days left. Plots above<br />

the line mean you’re a bit<br />

behind schedule.<br />

If you’re plotting<br />

below the line, you’re<br />

ahead <strong>of</strong> schedule.<br />

Days left in this iteration<br />

We’ll talk a lot more about burndown<br />

in the next few chapters.<br />

Don’t worry if you’re still a little fuzzy<br />

on how burn-down rates work, and how<br />

to track it. You’ll start creating a chart <strong>of</strong> your own in the<br />

next chapter, tracking your project’s progress.<br />
