📊 CORE KPI: CFD – Cumulative Flow Diagram

🔍 Content

The CFD visualizes the number of tasks in each process phase – over a selected period of time. You can see:

The KPI Cumulative Flow Diagram + (process board name) is automatically created when a new process board is set up.

✨ Tip: The KPI also appears automatically for existing boards.

The CFD shows you:

These values are displayed in sub-tiles from left to right:

Each phase has its own color (green to blue)
Colored areas in the CFD are stacked: the higher the area, the more tasks in that phase
Deleted phases are still shown in the timeline, but not in the legend

Unit & format

KPI	Unit	Data type
Inventory, Completed	Count	Integer
Cycle time	d to y	Decimal (1-DP)

ℹ️ Info: The time unit adapts to the selected period:

Tooltip: Shows date, values per phase, and note (deleted) if applicable
Legend: At the bottom, switchable between Range and Throughput
- Throughput = slope of the green curve (e.g. items/day)

Inventory
Number of active tasks per phase at time X

Cycle time
⌀ Time between start and completion of an item (including start day)

Completed
Sum of all completed or archived tasks in the period

Formulas

ℹ️ Info: All calculations are performed in real time, adjusted to the team’s time zone.

✨ Tip: Use the Throughput legend to easily visualize process comparisons.

❓ FAQ

Why do I see “N/A” in the tile?
This happens when no data is available – for example, no completed tasks in the selected period.

Can I change the unit of cycle time?
No, the unit is automatically chosen based on the period (days, weeks, months, years).

What happens to archived tasks?
They count as completed tasks and are included in the calculations.

This article describes the structure, calculation, and interaction options of the core KPI Cumulative Flow Diagram (CFD). The goal is to transparently show process performance and its progression over time.
