Question

Quizplus · Accepted Answer

A Pareto chart is a graphical representation of the relative frequency or size of problems. It helps to identify the most significant issues and prioritize them for improvement. It is most useful when looking at the prevalence of different defects or problems that have been found. It also assists in identifying the vital few sources of errors that contribute to most of the defects. Option A is incorrect because a Fishbone diagram is more useful in showing causes and effects of quality problems. Option C is incorrect because a Pareto chart is precisely the tool to use when investigating a quality issue. Option D is incorrect because a Pareto chart does not involve specifications limits; it is used primarily for classification purposes.
