If you’re tired of playing detective with your team’s workflow, you’re not alone. Bottlenecks and delays don’t announce themselves, but they wreak havoc all the same.
A Cumulative Flow Diagram (CFD) can change everything. It gives you a clear, visual breakdown of where tasks are piling up and how work is moving without any guesswork.
Curious about how this simple yet powerful chart can enhance clarity in projects? Let’s explore why CFDs are a must-have for managing workflows.
What is a Cumulative Flow Diagram and How to Read it
⏰60-Second Summary
- A Cumulative Flow Diagram (CFD) is a visual chart that tracks task progress through workflow stages like ‘To Do,’ ‘In Progress,’ and ‘Done’
- The X-axis represents time, while the Y-axis shows the cumulative number of tasks. Colored bands represent different workflow stages
- Widening ‘In Progress’ bands indicate bottlenecks and steady ‘Done’ slopes show consistent progress
- Teams can use CFDs to monitor workflow stability, predict timelines, and optimize processes
- Tools like make creating and reading CFDs simple and effective
Understanding Cumulative Flow Diagrams
A Cumulative Flow Diagram (CFD) gives you a clear picture of how work moves through your process. It shows how many tasks are in ‘To Do,’ what’s ‘In Progress,’ and what’s already ‘Done.’ It’s a simple, effective way to track progress, spot bottlenecks, and keep your projects running smoothly.
Watching how these layers shift over time reveals the story of your workflow. If the ‘In Progress’ band keeps expanding, it might be a sign your team is handling more than they should. On the other hand, a steadily growing ‘Done’ band is a reassuring signal that tasks are being completed at a solid, consistent pace.
Key components of a Cumulative Flow Diagram
Each part of the CFD tells a specific story about your project’s progress, helping you identify the smooth-flowing tasks and the roadblocks to create a stable process. Let’s dig deeper into each element and why it matters when tracking project progress:
Time (X-Axis)
The horizontal axis represents time, often in days, weeks, or sprints. It’s where you get to watch how things unfold over time. Pay attention to it, and you’ll start noticing trends, spotting patterns, and maybe even predicting what’s coming next.
Example: You might notice that work tends to pile up on Mondays—a classic case of the Monday blues! This is where workflow design software can help smooth things out. On the flip side, you’ll see tasks speeding up as sprint deadlines approach, proving that a little pressure can go a long way in getting things done.
Work items (Y-Axis)
The vertical axis tracks the cumulative count of work items, like tasks or tickets. Since it’s cumulative, the graph only rises as new tasks enter the system, giving you a clear picture of how work is building up over time.
Example: If your team starts with 50 tasks in the ‘Backlog’ and adds 20 more mid-week, the vertical axis will show a total of 70 tasks. This gives you a clear view of how your workload is growing over time.
Workflow states
Each stage of your workflow—like ‘Backlog,’ ‘In Progress,’ ‘Testing,’ or ‘Done’—gets its own color-coded band. These bands stack up on top of each other, and the width shows how many tasks are sitting in each stage.
A narrow band means fewer tasks are in that stage, which makes sense for something quick, like assigning tasks. But a wide band? That’s a red flag—more tasks could mean things are stalled or waiting for approvals.🚩
Example: Let’s say a development team’s CFD shows the ‘Testing’ band suddenly getting wider. That’s a signal that something’s off with that workflow. But since you find that out immediately, you can apply workflow optimization strategies to prevent further damage.
Throughput line
The throughput line, usually represented by the ‘Done’ band, shows how quickly tasks are getting finished over time. If the ‘Done’ layer is consistently sloping upward, you’re in good shape with steady progress and a healthy workflow.
But if it flattens out or barely moves, that’s a sign things might not be moving as smoothly as they should.
Example: A marketing team might notice their ‘Done’ line staying flat during campaign reviews, which could be a sign that things are getting stuck. It might mean the review process is dragging on, prompting them to optimize their processes and get things moving faster.
Benefits of using CFDs for data and information visualization
CFDs offer a clear view of your workflow, helping you spot issues early, maintain continuous process improvement, and get a more accurate sense of when tasks will be completed. And that’s just the beginning!
Let’s see how CFDs make managing your projects smoother:
✅ Data-driven decisions: Back up your decisions with hard data, leading to more focused team discussions
✅ Accurate delivery timelines: Track throughput for a data-driven way to predict when work will be done
✅ Workload distribution: Balance the workload for smoother operations by analyzing if resources are overloaded or underutilized
✅ Enhanced collaboration: Collaborate with your team and align on what needs attention with clarity on where things stand
✅ Risk mitigation: Spot when a particular stage is slowing down and take proactive action to keep things moving smoothly
Creating a Cumulative Flow Diagram
A CFD is more than putting together data. So, how do you create a CFD, ensuring no stones are left unturned? Let’s understand how to do this quickly:
Step-by-step guide to setting up a CFD in Kanban
Here’s how you can create CFDs that guide actions in Kanban:
Step 1: Track work items
Input all your tasks and subtasks into a project management system to stay organized and efficient.
By consolidating everything in one platform, you can manage tasks, track progress, and communicate with your team seamlessly. Ensure that each task has a detailed description and is categorized according to your workflow, making it easier to stay on top of responsibilities and deadlines.
Step 2: Define workflow stages
Every task goes through several process stages in its life cycle. The stages of a task in Agile projects may be to-do, in-progress, done, testing, etc.
Step 3: Log Data
Once your setup is complete, it’s time to log data regularly.
Record data across multiple metrics like start and end dates, time estimates, time tracking, priority, task status, and much more.
Integrating CFDs with Azure DevOps Server
For teams using Azure DevOps, integrating cumulative flow diagrams is straightforward. It helps you track project progress and improve efficiency with ease.
Let’s create our first CFD with Azure DevOps:
Step 1: Start by signing in to the Azure web portal. Next, select the project you want to add the board in. Then, click on Boards and select the correct team for the board.
Now, you need to select the backlog level for your kanban board. Backlogs are a list of items for the team to start working on. It’s like a reservoir of work that the team can draw from as per their capacity. Select the one that best fits your work process or methodology.
The backlogs defined for each default process in Azure DevOps are:
- Agile: Stories, Features, and Epics
- Basic: Issues and Epics
- Scrum: Backlog items, Features, and Epics
- Capability Maturity Model Integration (CMMI): Requirements, Features, and Epics
💡Pro Tip: Try to minimize the number of columns by deleting and keeping the most relevant ones for your team. This will keep your workspace clean.
Step 2: Let’s now add work items. Simply click on New item and enter the title. Once done, click Enter. All the items can be added in this way. They get saved automatically in the system.
If you want to add users to collaborate with you on this board. Simply copy the link to the board and send it to them.
Step 3: Once your board is created and used for weeks by your team, it’s time to analyze the Kanban Board. Click on the Analytics tab and click on View full report.
You can hover over the board to see how many work items are in which state.
Tips for configuring CFDs on a business dashboard
A CFD is a vital tool to visualize work progress. When configured with a business dashboard, it becomes even more powerful.
Here are some tips to help you configure it:
- Clear objectives: Set clear objectives to help your team focus on the most important data points
- Data updates: Set up periodic checks to ensure task statuses are updated. Even minor discrepancies, like leaving completed tasks marked as ‘In Progress,’ can distort the diagram
- Customized metrics and filters: Make your CFDs more insightful by configuring filters for metrics like task type, priority, or assignee. For example, you can display separate CFDs for high-priority tasks to track their progress independently
- Accessibility and collaboration: Avoid overwhelming diagrams with too many data points or visual clutter. Use these kanban board examples to create a CFD that everyone on your team can understand and use
Interpreting Cumulative Flow Diagrams
Cumulative Flow Diagrams (CFDs) provide a visual representation of your team’s progress and overall workflow. Each band on the cumulative flow diagram shows a different workflow stage, such as To Do, In Progress, or Done.
The thickness and gradient of these bands offer insights into the workload distribution and pace of task completion.
CFDs also track cycle time and lead time.
Cycle time shows how long it takes to complete tasks once they start, while lead time measures the total duration from task creation to completion.
By monitoring these metrics, teams can benchmark their performance and identify areas needing improvement.
A well-functioning workflow results in parallel bands on the CFD, indicating smooth task transitions. If the bands become irregular or one dramatically thickens, it’s time to investigate.
For example, a sudden widening of the ‘To-Do’ band might mean your team is overloading the backlog. Similarly, a bottleneck in the ‘Review’ stage could indicate delays in approvals or quality checks.
The slope of the ‘Done’ band is equally telling. A steep upward slope shows high productivity, while a flatter slope signals a slowdown. Patterns like these make it easier to anticipate issues and adapt accordingly.
When creating your CFDs, you need a tool with robust features, such as real-time updates, customizable workflows, and built-in reporting capabilities.
But each tool is unique in itself, so consider these factors:
- Team size and structure: Consider using tools like Trello for smaller teams while opting for robust platforms like for larger, more complex projects.
- Integration capabilities: Ensure the tool integrates with your existing systems, such as Slack, GitHub, or Google Workspace
- Reporting needs: Prioritize tools with advanced visualization options like ’s dashboards if in-depth analytics and reporting are critical to your project
- Ease of use: Pick a tool that is user-friendly to reduce onboarding time and encourage team adoption
