A Burn-down Chart displays the amount of remaining work over time. The vertical axis represents the total work remaining (often measured in story points, hours, or number of items), while the horizontal axis shows time (days in a Sprint or Sprints in a Release). The chart typically shows an ideal trend line indicating the expected rate of completion and an actual line showing real progress. When the actual line is above the ideal line, the team is behind schedule. When below, they are ahead. This visualization helps teams quickly identify if they need to adjust their approach to meet commitments.
A Burn-up Chart takes a different approach by showing work completed over time rather than work remaining. It displays two lines: one representing the total scope of work and another showing cumulative completed work. The gap between these lines indicates remaining work. A key advantage of burn-up charts is their ability to clearly show scope changes. When new work is added, the total scope line moves up, making scope creep visible to everyone.
For Product Owners, these charts provide valuable transparency when managing stakeholder expectations. They enable data-driven conversations about delivery forecasts and help identify when scope adjustments might be necessary. Burn-up charts are particularly useful for Release planning as they accommodate scope changes more gracefully than burn-down charts.
Both charts support empirical process control by providing inspection opportunities. Teams can adapt their strategies based on the trends these charts reveal, making them powerful tools for managing products with agility and maintaining alignment between development progress and business objectives.

Why Burn-down and Burn-up Charts Are Important
Burn-down and burn-up charts are essential visual tools for Product Owners and Scrum Teams to track progress and communicate status to stakeholders. They provide transparency into how work is progressing toward a goal, whether that's a Sprint Goal or a Product Goal. Understanding these charts helps Product Owners make informed decisions about scope, release planning, and stakeholder expectations.
What Are Burn-down Charts?
A burn-down chart is a graphical representation showing the amount of work remaining over time. The vertical axis represents the remaining work (often in story points or hours), while the horizontal axis represents time (days in a Sprint or Sprints in a release).
Key characteristics: • Starts with total work at the top left • Ideal trend line slopes downward toward zero • Actual progress line shows real remaining work • Easy to see if the team is ahead or behind schedule
What Are Burn-up Charts?
A burn-up chart shows work completed over time, with an additional line indicating the total scope. The vertical axis shows work units, and the horizontal axis shows time.
Key characteristics: • Work completed line starts at zero and rises • A separate line shows total scope • Scope changes are visible when the total scope line moves • Provides better visibility into scope creep
How They Work
Burn-down Chart Mechanics: • Plot total remaining work at the start • Update remaining work daily or per Sprint • Compare actual progress against the ideal trend • When the line reaches zero, all planned work is complete
Burn-up Chart Mechanics: • Plot completed work starting from zero • Draw a horizontal line for total planned scope • As work completes, the completed line rises • When completed work meets total scope, the goal is achieved • If scope increases, the total scope line moves up, showing the impact
Key Differences Between Burn-down and Burn-up
• Scope visibility: Burn-up charts clearly show scope changes; burn-down charts can hide them • Direction: Burn-down goes from high to low; burn-up goes from low to high • Stakeholder communication: Burn-up charts are often better for showing scope creep impact • Simplicity: Burn-down charts are simpler to read for basic progress tracking
Product Owner Perspective
As a Product Owner, these charts help you: • Forecast when features might be delivered • Communicate progress to stakeholders transparently • Identify when scope changes affect delivery dates • Make informed decisions about adding or removing scope • Support release planning with empirical data
Exam Tips: Answering Questions on Burn-down and Burn-up Charts
1. Remember the purpose: These are transparency and forecasting tools, not tools for measuring team performance or holding teams accountable.
2. Know when to use each: If a question involves tracking scope changes, burn-up charts are typically the better answer. For simple remaining work visualization, burn-down charts work well.
3. Understand limitations: These charts show trends but do not guarantee outcomes. They support empirical decision-making based on actual progress.
4. Focus on empiricism: Both charts support the Scrum pillar of transparency by making progress visible to everyone.
5. Watch for trap answers: Avoid answers suggesting these charts should be used to pressure teams or predict exact completion dates with certainty.
6. Connect to Product Ownership: Questions may ask how Product Owners use these tools for stakeholder communication and release planning decisions.
7. Scope change visibility: If a question asks about making scope changes visible, burn-up charts are the correct choice because they show both completed work and total scope on separate lines.
Common Exam Scenarios
• A stakeholder wants to understand why a release date changed - use burn-up to show scope additions • The team wants to see Sprint progress - either chart works, but burn-down is common for Sprints • Product Owner needs to forecast release dates - use historical velocity data with these charts • Making progress transparent to all stakeholders - both charts serve this purpose effectively
