Cumulative Flow Diagram

Overview

The Cumulative Flow Diagram (CFD) plots the count of issues in each workflow stage on every day of your chosen date range. Each stage is a colored band stacked on the others, so the total height of the chart always equals your total issue count. Watching how bands grow and shrink tells you whether work is flowing smoothly or piling up.

Overview

FeatureDescription
Stacked Area ChartOne colored band per workflow stage - bands stack to show total WIP
6 Band ModesStatus categories, individual statuses, board columns, board column categories, work item types, custom field values
Calculate ByIssue count, Story Points, Story Point Estimate, Original Time Estimate, or any custom numeric field
Board IntegrationConnect to a Jira Software board to use its column definitions as bands
Sprint & Release ScopingScope the CFD to a specific sprint (including "latest sprint auto") or release version
Flexible Date RangesRolling windows, fixed ranges, sprint dates, or release dates
Include Sub-TasksToggle to include or exclude sub-tasks from the analysis
Band CustomizationReorder, hide, and color-code individual workflow bands

How to Read a CFD

  • Band width (vertical height at any date) = number of issues currently in that stage
  • Narrow bands = work moves through quickly (good)
  • Wide bands = work is accumulating (potential bottleneck)
  • Flat top line = no new work is being added (stable scope)
  • Rising top line = new issues are being added (scope growth)
  • Steepening right edge = accelerating completion (delivery speed increasing)

Data Sources

Source TypeWhen to Use
ProjectsAnalyze all issues in one or more Jira projects
Saved FilterUse a pre-saved Jira filter as the issue scope
Custom JQLWrite a JQL query for precise scoping (e.g., a specific component or epic)
Jira Software BoardConnect to a board to inherit its column definitions as CFD bands

Interpreting Common CFD Patterns

Healthy Flow

All bands are roughly proportional and the total height grows steadily. Done band widens progressively. No single band dominates.

Bottleneck

One band (e.g., "In Review") grows consistently wider over time while later bands stay flat. Work is entering the stage faster than it is leaving. Address the bottleneck stage's capacity.

Scope Creep

The top of the chart keeps rising even as the Done band grows. New work is being added faster than it is being completed.

Stalled Sprint

The chart goes flat across all bands for multiple days. Work is not moving - investigate blockers, dependencies, or team availability.
