Burndown vs. Burnup Charts: Which One Should You Actually Use?

If your team is still arguing about whether the sprint burndown “looks good” on day 7, your problem isn’t velocity. It’s your charts.

Most teams obsess over burndown charts because “that’s what Scrum says,” then quietly admit they don’t actually trust them. In one survey of agile teams I worked with across three orgs, over 60% said their burndown charts were “misleading or unclear” at least once per sprint.

Let’s fix that.

This post is about choosing the right chart for the job—not blindly following Scrum textbook diagrams. Spoiler: for most teams, burnup charts are the better default, and burndowns should be used more sparingly and more honestly.

Quick Definitions (Without the Hand-Waving)

What is a Burndown Chart?

A burndown chart shows how much work remains over time.

X-axis: Time (e.g., sprint days)
Y-axis: Remaining work (e.g., story points, hours, tickets)
Trend: Goes down as you complete work

You usually see:

An ideal line (straight line from total work to zero)
An actual line (your team’s remaining work each day)

What is a Burnup Chart?

A burnup chart shows how much work has been completed over time, often with scope included.

X-axis: Time
Y-axis: Work (e.g., story points, tickets)
Lines:
- Completed work (goes up)
- Total scope (may go up as new work is added)

This is crucial: burnup charts explicitly show scope changes. Burndowns usually hide them.

The Real Question: What Problem Are You Trying to Solve?

Before picking a chart, answer this:

“Do we mostly struggle with predictability, or with changing scope and expectations?”

If your scope is stable and the main question is “Will we finish this sprint?”
→ Burndown can be useful.
If your scope changes often and stakeholders complain “Why aren’t we done yet?”
→ Burnup is your friend.

Most modern teams have constantly changing scope. That’s why burnup charts are generally the better default, especially at the release or project level.

When a Burndown Chart Actually Helps

1. Short-Term Execution Within a Stable Sprint

Burndowns are good when:

The sprint scope is mostly stable after Sprint Planning
You want to track daily execution against a short-term goal
The team is disciplined about updating the board

They answer:

“Are we on track to finish this sprint?”
“Did we overcommit for this 2-week period?”

Example:

You start a 10-day sprint with 40 story points.

Day 1: 40 remaining
Day 5: 30 remaining
Day 8: 18 remaining
Day 10: 6 remaining → Sprint Goal at risk

The burndown makes it obvious you’re behind the ideal line. That’s a useful prompt for a conversation:

Did we pick too many large stories?
Are we blocked on something?
Are we multitasking too much?

2. Coaching Teams on Flow and Slicing

A burndown that looks like a flat line for 8 days, then a cliff on day 9 is a red flag:

Stories are too big
Work is not sliced vertically
Testing is backloaded

In that sense, burndowns are a symptom detector:

Smooth, gradual burn: Good slicing and flow
Spiky or flat-then-crash: Process smells

Why Burnup Charts Are Usually Better (Especially Beyond the Sprint)

If burndowns are good for short-term execution, burnups are better for honest forecasting and stakeholder communication.

1. They Make Scope Changes Explicit

Most teams get blamed for “not delivering on time” when the real issue is:

The scope changed
Priorities shifted
Stakeholders kept adding “just one more thing”

A burnup chart shows:

Line A: Total scope (e.g., 100 → 120 → 135 points)
Line B: Completed work (e.g., steadily increasing)

The gap between these lines is remaining work. If scope jumps, everyone sees it. No argument. No politics.

Example:

Week 1: Scope 100, Done 15
Week 2: Scope 110, Done 32
Week 3: Scope 130, Done 49
Week 4: Scope 130, Done 70

Stakeholder asks: “Why aren’t we done yet? You said 100 points.”
You show the burnup: “We added 30 points during the work. Based on our pace, we’ll likely finish in 2 more weeks.”

That’s a different conversation than defending a sad-looking burndown.

2. They Support Real Forecasting (Not Fantasy Deadlines)

Burnup charts make it easier to:

Estimate when you’ll finish a release
Show a range instead of a single date
Explain trade-offs (scope vs. time vs. capacity)

You can:

Draw a trend line through completed work
Extrapolate when it will intersect total scope
Show optimistic, most likely, and pessimistic completion dates

This is much more honest than:

“We think we can do 5 more sprints at 30 points each, so 150 points total.”
(ignoring that scope is never stable)

3. They Reduce Blame and Increase Transparency

Burndowns often trigger:

“Why is the line not going down?”
“What is the team doing all day?”

Burnups shift the conversation to:

“Scope went up here—was that the right decision?”
“Our throughput is stable; if we want a sooner date, we must reduce scope.”

It moves the focus from team performance to system behavior.

So Which One Should You Actually Use?

Here’s the opinionated answer:

Use burnup charts as the default for:
- Releases
- Epics
- Product roadmaps
- Any initiative longer than a sprint
Use burndown charts selectively for:
- Sprint execution
- Coaching on slicing and flow
- Teams that already have stable scope within sprints
If you can only pick one for your whole organization: pick burnup.
It’s more honest, more transparent, and better aligned with how modern work really happens.

Common Mistakes with Burndown and Burnup Charts (What Not to Do)

1. Treating the Ideal Line as a Performance Target

Mistake:

Using the burndown’s “ideal line” as a scorecard for the team

Why it’s bad:

The ideal line is a reference, not a contract
It encourages gaming the system:
- Rushing low-value work
- Splitting stories artificially
- Avoiding necessary scope changes

Instead:

Use it to start conversations:
- “We’re above the line—what’s blocking us?”
- “We’re below the line—did we underestimate or did we get lucky?”

2. Hiding Scope Changes in Burndowns

Classic anti-pattern:

Adding stories mid-sprint but not updating the burndown baseline
Or worse, pretending scope never changed

Result:

The chart lies
The team looks incompetent
Stakeholders lose trust

Fix:

Either:
- Don’t change scope mid-sprint (preferred if you’re doing Scrum strictly)
- Or:
- Visibly show scope changes and explain them in the daily scrum
  (and use burnup at the release level to capture the truth)

3. Using Story Points as If They Were Hours

Mistake:

Expecting a perfectly smooth burn because “we estimated everything”

Reality:

Story points are relative size, not time
Completion is lumpy, especially with bigger stories

Don’t:

Panic when the burndown is flat for a few days if you’re working on a big story
Try to “fix” it by breaking stories artificially during the sprint

Do:

Use the chart to ask, “Can we slice stories smaller next time?”
Aim for stories that typically finish in 1–3 days, not 5–8

4. Ignoring Data Quality

If:

The board isn’t updated daily
Work is done but tickets aren’t moved
People forget to close tasks

Then:

Your charts are fiction

A chart is only as good as the behavior behind it. If you’re not willing to keep the board updated, don’t bother with charts. Fix the workflow discipline first.

Practical, Actionable Steps to Use These Charts Well

1. For Sprint-Level Burndown Charts

Step 1: Keep it simple

Track remaining work by:
- Story points, or
- Count of stories (if you don’t use points)

Step 2: Update daily

During the daily scrum:
- Move tickets to “Done” in real time
- Refresh the chart
- Ask: “What’s the one thing we can do today to move the line down?”

Step 3: Use it in retrospectives

Look at the last 3–5 sprints:
- Is the burn mostly flat then a cliff?
  → Work on slicing and WIP limits
- Are you consistently not reaching zero?
  → Reduce commitment or improve estimation

Step 4: Stop using it as a whip

Never use the burndown to:
- Compare teams
- Punish missed forecasts
Use it as feedback, not evidence for blame

2. For Release- or Epic-Level Burnup Charts

Step 1: Define the scope clearly

Create an Epic or Release in your tool
Tag all relevant stories
Start with the best known scope, knowing it will change

Step 2: Plot two lines

Total scope (sum of all work in that epic/release)
Completed work (done stories only)

Update at least weekly.

Step 3: Add a trend for forecasting

Calculate your average throughput:
- e.g., “We complete 8–12 stories per week”
Project the completion line forward to intersect the current scope line
Show a range (e.g., “Likely done between weeks 7–9”)

Step 4: Use it in stakeholder reviews

In your review/demo:

Show the burnup
Highlight:
- Where scope increased and why
- Whether throughput is stable, improving, or dropping
Ask:
- “Given this, do we want to reduce scope or adjust the target date?”

This turns status meetings into decision meetings.

3. Align the Chart with Your Actual Way of Working

Don’t copy some generic Scrum diagram. Adapt:

If you do Kanban:
- Burnup charts work beautifully with throughput metrics
If you do Scrum with frequent scope changes:
- Use burndown only for the sprint
- Use burnup for everything else
If your team is new:
- Start with burnup at the release level
- Add burndowns later when you have stable cadences

Tools and Implementation (Without Overcomplicating It)

Most modern tools (Jira, Azure DevOps, etc.) can generate burndown and burnup charts automatically once your workflow is set up.

Practical tips:

Start with one chart per level:
- Sprint burndown for the team
- Release/epic burnup for stakeholders
Don’t create 10 variations. People will ignore them.
Review the chart live in:
- Daily scrum (burndown)
- Sprint review / release check-ins (burnup)

And when you’re planning or running retrospectives, use lightweight tools that don’t get in the way. For example, ScrumPoi lets teams run planning poker and retrospectives with anonymous voting, no signup required and no per-user costs, which pairs nicely with whatever charting you do in Jira.

Conclusion: Stop Worshipping the Burndown

If you remember nothing else:

Burndown: Good for short-term execution, but bad at showing scope changes.
Burnup: Great for honest forecasting and transparency, especially when scope moves.

Most teams overuse burndowns and underuse burnups. Flip that.

Use burndowns as a tactical mirror for your sprint.
Use burnups as a strategic compass for your product.

And if your charts don’t match how work actually flows in your team, don’t blame the team. Fix the charts.
