A Pareto diagram focuses attention on which of the following?
A.
Identifying the stage of failure during the process
B.
Predicting future problems based on historic results
C.
Checking for variances in quality over time
D.
Locating defects with the highest occurrence
Explanation:
The purpose of the Pareto chart is to highlight the most important among a (typically large) set of factors. In quality control, it often represents the most common sources of defects, the highest occurring type of defect, or the most frequent reasons for customer complaints, and so on. Wilkinson (2006) devised an algorithm for producing statistically based acceptance limits (similar to confidence intervals) for each bar in the Pareto chart.
