Imagine you are on a solo road trip with a set destination. You constantly check your map and fuel gauge to check whether you are on a track. Now, replace the road trip with an agile project and the map with a burndown chart.
Just like a map guides your journey, a burndown chart provides a clear picture of how much work has been completed and what remains.
Burndown charts are visual representations of the team’s progress used for agile project management. They are useful for scrum teams and agile project managers to assess whether the project is on track.
Burndown charts are generally of three types:
The product burndown chart focuses on the big picture and visualizes the entire project. It determines how many product goals the development team has achieved so far and the remaining work.
Sprint burndown charts focus on the ongoing sprints. It indicates progress towards completing the sprint backlog.
This chart focuses on how your team performs against the work in the epic over time. It helps to track the advancement of major deliverables within a project.
A burndown chart shows the amount of work remaining (on the vertical axis) against time (on the horizontal axis). It includes an ideal work completion line and the actual work progress line. As tasks are completed, the actual line "burns down" toward zero. This allows teams to identify if they are on track to complete their goals within the set timeline and spot deviations early.
A burndown chart is a visual tool used by agile teams to track progress. Here is a breakdown of its key functions:
Burndown charts allow agile teams to visualize the remaining work against time which helps to spot issues early from the expected progress. They can identify bottlenecks or obstacles early which enables them to proactive problem-solving before the issue escalates.
The clear graphical representation of work completed versus work remaining makes it easy for teams to see how much they have accomplished and how much is left to do within a sprint. This visualization helps maintain focus and alignment among team members.
The chart enables the team to see their tangible progress which significantly boosts their morale. As they observe the line trending downward, indicating completed tasks, it fosters a sense of achievement and motivates them to continue performing well.
After each sprint, teams can analyze the burndown chart to evaluate their estimation accuracy regarding task completion times. This retrospective analysis helps refine future estimates and improves planning for upcoming sprints.
Open a new sheet in Excel and create a new table that includes 3 columns.
The first column should include the dates of each sprint, the second column have the ideal burndown i.e. ideal rate at which work will be completed and the last column should have the actual burndown i.e. updating them as story points get completed.
Now, fill in the data accordingly. This includes the dates of your sprints and numbers in the Ideal Burndown column indicating the desired number of tasks remaining after each day throughout the let’s say, 10-day sprint.
As you complete tasks each day, update the spreadsheet to document the number of tasks you can finish under the ‘Actual Burndown’ column.
Now, it’s time to convert the data into a graph. To create a chart, follow these steps: Select the three columns > Click ‘Insert’ on the menu bar > Select the ‘Line chart’ icon, and generate a line graph to visualize the different data points you have in your chart.
A Burndown chart mainly tracks the amount of work remaining, measured in story points or hours. This one-dimensional view does not offer insights into the complexity or nature of the tasks, hence, oversimplifying project progress.
Burndown charts fail to account for quality issues or the accommodation of technical debt. Agile teams might complete tasks on time but compromise on quality. This further leads to long-term challenges that remain invisible in the chart.
The burndown chart does not capture team dynamics or collaboration patterns. It fails to show how team members are working together, which is vital for understanding productivity and identifying areas for improvement.
The problems might go unnoticed related to story estimation and sprint planning. When a team consistently underestimates tasks, the chart may still show a downward trend. This masks deeper issues that need to be addressed.
Another disadvantage of burndown charts is that they do not reflect changes in scope or interruptions that occur during a sprint. If new tasks are added or priorities shift, the chart may give a misleading impression of progress.
The chart does not provide insights into how work is distributed among team members or highlight bottlenecks in the workflow. This lack of detail can hinder efforts to optimize team performance and resource allocation.
Burndown charts are great tools for tracking progress in a sprint. However, they don’t provide a full picture of sprint performance as they lack the following dimensions:
Typo’s sprint analysis feature allows engineering leaders to track and analyze their team’s progress throughout a sprint. It uses data from Git and the issue management tool to provide insights into getting insights on how much work has been completed, how much work is still in progress, and how much time is left in the sprint hence, identifying any potential problems early on and taking corrective action.
Burndown charts offer a clear and concise visualization of progress over time. While they excel at tracking remaining work, they are not without limitations, especially when it comes to addressing quality, team dynamics, or changes in scope.
Integrating advanced metrics and tools like Typo, teams can achieve a more holistic view of their sprint performance and ensure continuous improvement.
