Burndown Chart: What it is, How to Use it, Example 2023

One of my favorite things about Jira is the ability to shape your project to fit your methodology right from the start, including agile and scrum. It’s one thing to talk about your progress, and it’s another to see your progress on display with hard numbers and a chart to back it up. It’s harder to confuse the progress of your work when the data is right in front of you. However, if you’re looking for additional justification, I’ve listed three benefits for using these reports as part of your project management plan. The term “burn chart” is sometimes encountered, possibly as a generalization covering variants such as the “burn up chart”. In this Scrum Tapas video, Professional Scrum Trainer Ralph Jocham describes Burndown Charts and focuses on the work within a Sprint.

At the end of the fifth day, each of the tasks should add up a total of 80 hours as estimated in the first step. Integrating the usage of burn-down charts in your project endeavors will help make the process easier for you and your team and also hopefully aid in success. Another benefit of using a burn-down chart is that it helps keep a team motivated. This is because seeing progress daily will help keep a team dedicated and motivated to finish the work in the stipulated time frame. Teams compare these two lines to determine how much their work differs from the ideal work and if they are on schedule to complete the project. Comparing these two lines also gives them an insight into the bottlenecks in their progress.

Burndown chart

A burndown chart helps analyze the work you have to do versus the time it takes you to complete it. This can be an excellent tool to visualize and better manage your team’s workload so you can prioritize your schedule. Let’s dig into what a burndown chart is and how to create one of your own. Usually shown in days, the X-axis represents the amount of time left to complete the project. It can be identified easily as it is the horizontal axis on the chart.

  • For both types of burndown charts, the y-axis (vertical) represents the amount of work to be done and the x (horizontal) axis represents the time allotted to do it.
  • A burndown chart can be used not only to estimate time but also to estimate outcomes.
  • The release burndown chart gives you a longer term view of your team’s progress.
  • These tasks can be assigned to the team member or members you feel will best execute them.
  • However we have to be careful when using this model since the rate of change will be high in the beginning of the project but will drop at the end.

A burndown chart can be used to visually represent this work management baseline and this can aid in efficiency. The actual line in a burn-down chart may be straight or it might not. Most projects are faced with unforeseen obstacles and issues which deter work progression. In most cases, the burndown chart definition actual work line is different from the initial estimate due to the aforementioned reason. Moving up from zero or down from zero is the core visual appeal of each, but the burn up chart’s use of a scope line offers more flexibility for teams with regularly changing project expectations.

Limitations of Burndown Charts

However, if the scope of the product is ever-changing, it’s better to use a burnup chart because it allows showcasing progress at every step and even allows the option of adding more work along the way. A burndown chart is a chart often used in scrum agile development to track work completed against time allowed. The x-axis is the time frame, and the y-axis is the amount of remaining work left that is labeled in story points and man hours, etc.

The actual work most times does not meet this set sprint goal due to obstacles that inevitably arise during a project. But having a set goal to work towards helps keep the team motivated. Typically used by agile teams, story points are used to estimate work that is remaining. Burndown charts also provide your team’s estimated time to complete the work when it gets integrated with the velocity estimate. It also helps to pick out any scope creep because, in that case, the sprint will take longer to complete than expected.

What are the limitations of a burndown chart?

Project managers also add a second graph line called “actual effort” to visualize the amount of work or hours that were actually put in during that time period. Burndown charts appear to be entirely original to the Scrum community; the term does not seem to have a prior use elsewhere in relation to managing software projects or other efforts. You can do this by gathering your estimates and comparing them against your logged time.

While the expected progress line (red) is often a straight line pointed toward the end goal, this can also be a flexible line to show which sprints will require the most effort. We’ll add our values to the scheduled column, which represents the number of tasks you’d like to have left at the end of each day of the 10-day sprint. It’s easier to keep going on a project if we can see how far we’ve already come. This is why it makes a ton of sense to use your burndown to motivate your teams, especially if and when you make a big leap toward your end goal. And it’s time to press pause and find out what that problem is and how to address it. Either way, the earlier you catch the discrepancy, the earlier you can get the train back on the tracks.

The Benefits of BurnDown Charts

According to the Foundations of Agile Methodology course, failing to complete a Sprint is a common problem for new Agile teams who are learning how to work together and prioritize assignments. However, a burndown chart offers a great way to communicate visually to management how the process can improve for future Sprints. If they don’t, then they’re risking the successful completion of the project. A burndown chart is just one of the many tools that lead to project success.

The rightmost point of the chart indicates the start of a project or agile sprint while the leftmost point shows its end. A burndown chart (also known as a project burn rate chart or PERT chart) is a graph that shows how many project tasks are left to finish during a selected time period. Teams use it to keep track of progress and have a visual representation of the forecast.

What’s the difference between a burndown and burnup chart?

A second line—almost always less linear due to unexpectedly fast or slow tasks, interruptions, and innovations—represents the actual work remaining. There is an ideal work remaining line which is a straight line connecting the starting and ending points. This line represents the sum of estimates for all tasks that need to be completed. At the endpoint, the ideal line crosses the x-axis and shows there is no work left to be done. This line is based on estimates and therefore is not always accurate.

Nevertheless, suppose the scope of a product is constantly changing, and there is a need to show stakeholders progress at every step. In other words, burnup shows the team that they are just a few feet from the finish line! Burndown helps project managers understand whether they have mapped the terrain and planned the timing correctly to get the team across that finish line.

Sprint Planning with Burndown Charts

These lines will likely look slightly different unless your actual work ended up being the precise effort estimated at the beginning. Once you have your estimated effort, you can begin tracking your daily progress in order to start your burndown line. On the burndown chart, the ideal line and the actual work line start from the same point, indicating that no work has been done. The ideal work line represents the estimated remaining work with ideal conditions. It is the best-case scenario for the project without any delays or complications and is estimated before it starts. For example, The Y-axis may have story points ranging from 0 to 100 to reflect effort.
