What is a cumulative flow diagram?

Cumulative Flow Diagram (CFD) is a visual tool for tracking work progress in a project, often used in Agile and Kanban.

The diagram displays the cumulative number of tasks in different states (e.g., "To Do", "In Progress", "Done") over time. This allows seeing how the number of tasks changes at each stage, identifying bottlenecks, and assessing process stability.

Advantages of CFD:

• Helps control the flow of tasks and identify delays.
• Allows estimating the work completion rate.
• Visualizes the balance between process stages.

Example: if the "In Progress" area grows, it may indicate that tasks are delayed at this stage and the process needs optimization.
