If the distance between the arrival and departure curves on a team’s cumulative flow diagram is growing apart, what is likely happening?
A . Lead time is increasing
B . Unplanned work is pushed into the backlog
C . WIP is decreasing
D . The backlog is being reprioritized

Answer: A

Explanation:

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.
