ASQ Certified Quality Engineer (CQE) — Question 71
As a commonly used problem solving technique, which of the following would be the BEST application of a Pareto chart?
I. To determine when to make proactive adjustments to a process.
II. To differentiate between major and minor problem areas.
III. To gather data and to design experimental controlled changes.
IV. To evaluate the results of other problem solving techniques upon the product or service.
Answer options
- A. I and II only
- B. II and III only
- C. II and IV only
- D. I, II, III and IV
Correct answer: C
Explanation
The best application of a Pareto chart is to identify and distinguish between significant and minor problem areas (II) and to assess the impact of other problem-solving methods on the product or service (IV). Options I and III do not specifically relate to the primary function of Pareto charts, which focus on prioritizing issues rather than making proactive adjustments or designing experiments.
