Cumulative Flow Diagram (CFD):A CFD is a visual tool used in Kanban and Scrum to show the progress of work items through different stages of the workflow over time.

Arrival and Departure Curves:These curves represent the work items entering (arrival) and leaving (departure) the system.

Growing Distance:If the distance between the arrival and departure curves on the CFD is growing apart, it indicates that work items are taking longer to move through the system.

Lead Time:This term refers to the total time from when a work item is created until it is completed. An increasing distance between the curves means that work items are spending more time in the system, thus increasing the lead time.

SAFe materials on flow metrics and Kanban principles highlight the importance of monitoring lead time and using CFDs to identify bottlenecks and inefficiencies in the workflow.
