How is average lead time measured in a Kanban system?

Answer options

• A. By taking the average velocity over the last three iterations
• B. Measure the vertical distance between arrival and departure lines on a cumulative flow diagram
• C. Measure the horizontal distance between arrival and departure lines on a cumulative flow diagram
• D. Measure the lead time for at least three items and calculate the statistical mean of the items

Correct answer: D

Explanation

The correct answer is D because it directly refers to measuring the lead time for multiple items and calculating the average, which is essential for understanding performance in Kanban. The other options involve different metrics or measures that do not specifically address the calculation of average lead time.
