How is average lead time measured in a Kanban system?

Show Suggested Answer Hide Answer
Suggested Answer: C

In a Kanban system, average lead time is measured by observing the horizontal distance between the arrival and departure lines on a cumulative flow diagram (CFD). The CFD visualizes the flow of work items through various stages of the workflow. The horizontal distance between the points where work items enter and leave a particular stage represents the lead time. By calculating this distance over multiple items, teams can determine the average lead time, providing insights into process efficiency and areas for potential improvement.

A is tempting, but I feel B is more accurate for Kanban.

I prefer D. Calculating the mean gives a solid average.

I think it's B. The cumulative flow diagram shows the flow clearly.

A is totally wrong, velocity isn't the same as lead time!

Wait, are we sure about B? Seems too simple.

I thought it was D? Measuring lead time sounds right.

It's definitely B! Cumulative flow diagrams are key.

I definitely studied how to calculate average lead time, but I can't remember if it was about velocity or the distances on the diagram.

I feel like the answer might be B, but I can't recall exactly how the cumulative flow diagram works in this context.

I remember practicing a question like this, and I think measuring the lead time for multiple items was important, so maybe it's option D?

I think average lead time is related to the cumulative flow diagram, but I'm not sure if it's the vertical or horizontal distance.
