Burndown vs Burnup Charts: Which One Should Your Team Actually Use?
If you’ve run more than a handful of sprints, you’ve probably seen both a burndown chart and a burnup chart, and you’ve probably noticed they don’t quite show the same thing — even though they’re both trying to answer “are we going to finish this sprint?”
They’re not interchangeable. One of them hides information the other one shows, and for most small teams, that missing information is exactly what you need.
What a burndown chart shows
A burndown chart plots remaining work against time. You start at the top left with all your points (or hours, or tickets) and an ideal line slopes down to zero at the sprint’s end. Actual progress is plotted against that line — if you’re above it, you’re behind; below it, you’re ahead.
Burndown charts are simple and satisfying to watch trend toward zero. The problem is what happens when scope changes mid-sprint — and on most real teams, it does. If a new ticket gets added on day 4, the burndown line usually just resets or jumps, and it’s not obvious from the chart alone whether the team is behind because they’re not shipping, or because more work got added.
What a burnup chart shows
A burnup chart plots two lines: total scope, and completed work, both climbing upward over time. Instead of watching work disappear, you watch completed work rise to meet a scope line that can move independently.
This is the key difference: a burnup chart makes scope changes visible instead of hiding them. If scope creeps mid-sprint, the scope line visibly steps up, and you can immediately tell “we didn’t fall behind, the goalposts moved” — which is a completely different conversation than “the team isn’t shipping.”
Why this matters more for small teams
Larger teams with dedicated scrum masters often have separate scope-change tracking outside the chart itself — a backlog grooming ritual, a change log, a PM keeping tabs. Small teams usually don’t have that overhead, which means the chart itself needs to carry more of the signal.
For a 3-8 person team without a dedicated process person, a burnup chart answering “are we on track, and if not, is it because of scope or because of pace” in a single glance is worth more than the slightly more familiar burndown shape.
The practical answer
Use burnup if:
- Your team’s scope shifts mid-sprint even occasionally (most teams’ does)
- You want one chart to distinguish “behind because of scope” from “behind because of pace”
- You don’t have a separate process for tracking scope changes
Use burndown if:
- Your sprints have genuinely fixed, locked scope with a hard change-control process
- Your team is already fluent in reading it and retraining isn’t worth it
Seeing it in practice
ScoreZen tracks sprint progress with a burnup chart by default — cumulative points shipped against an ideal pace line, updated in real time as work lands (a card moves to Done, or a linked GitHub issue closes). It’s paired with a daily velocity view so you can see not just “are we on track” but “at what pace, and is that pace holding.”
If you’re currently eyeballing sprint progress from a spreadsheet or a Jira burndown that doesn’t quite tell the whole story, ScoreZen is free for teams up to 5 people, no credit card required.
