Answer :
Final answer:
The first step in constructing Pareto charts is to collate categorical data concerning quality issues. These charts help prioritize problem areas based on the Pareto Principle. Control charts are used to monitor process stability by plotting quality assessment data over time hence, answer is D) Pareto charts.
Explanation:
The first step in constructing D) Pareto charts is to gather categorical data relating to quality problems. Pareto charts are a type of bar chart and are used extensively for quality control purposes, as they help identify the most significant factors in a dataset and are based on the Pareto Principle (also known as the 80/20 rule). This rule suggests that roughly 80% of the effects come from 20% of the causes, and these charts help prioritize addressing the causes that will have the most substantial effect on improving quality.
Control charts, on the other hand, are utilized for performance-based quality assessment. These charts involve plotting quality assessment data, such as spike recoveries, over time to monitor consistency and identify any shifts out of statistical control. While Pareto charts help in identifying what to focus on, control charts are crucial in tracking performance and stability of processes.
