Cumulative Flow

A stacked chart of how many work items sat in each status on each day, which makes bottlenecks visible as a band that keeps widening.

What this screen is for

The cumulative flow diagram shows the make-up of your work over time. Each day is a column and each status is a coloured band, so you read the height of a band as the number of items sitting in that state on that day. A band that grows steadily wider is a bottleneck: work is entering that state faster than it leaves.

You choose a project and a window of the last 7, 14, 30, 60 or 90 days. The bands follow the statuses your company actually uses, so custom statuses appear with their own colour rather than being lumped together.

When to use it

Use it when delivery feels slow but no single sprint looks wrong — the diagram shows where work is queuing rather than how much of it there is.

What you see on this screen

  • The horizontal axis is Date, one point per day across the window you chose.
  • The vertical axis is Tasks — a count of work items. The bands are stacked, so the top of the chart is the total amount of work.
  • Each band is one state, named in the legend exactly as your company spells it, so a custom state appears under its own name and its own colour. Familiar ones keep familiar colours: grey for new, blue for active, purple for review, green for done.

Read the bands by their thickness rather than their height. A band that thickens steadily is collecting work faster than it releases it, which is where the delay is. A band that stays thin is a stage work passes straight through.

Filters and actions

Pick a project and a window: Last 7 days, Last 14 days, Last 30 days, Last 60 days or Last 90 days, starting at thirty. There are no tiles, no table and no export.

The short windows are for reading a current jam; the ninety-day window is for seeing whether a stage has been thickening for months.
