Visual analytics tool from Kanban methodology that displays work-in-progress, cycle time, throughput, and bottlenecks simultaneously through layered area charts for workflow optimization.
Завантаження......
A Cumulative Flow Diagram (CFD) is a powerful visualization tool adapted from Kanban methodology for time tracking and workflow analysis. It provides a layered view of all four important metrics simultaneously: work-in-progress, cycle time, lead time, and throughput.
The CFD is a stacked area chart where:
1. Work-in-Progress (WIP)
2. Cycle Time
3. Throughput
4. Lead Time
