APICS Certified Supply Chain Professional (CSCP) — Question 18

An operations manager wants to measure variability in the delivery time of insurance policies to clients. Which of the following quality tools most appropriately would show the level of variability?

Answer options

• A. Pareto chart
• B. Histogram
• C. Scatterplot
• D. Check sheet

Correct answer: B

Explanation

A Histogram is effective for displaying the distribution of data points, which allows the operations manager to see the variability in delivery times. The other options, such as the Pareto chart, scatterplot, and check sheet, do not provide a clear view of how data varies over a range, making them less suitable for this specific measurement.
