question

choosing the right tool for the job is key during a six sigma project.

for what studies would you use a pareto chart?

• determining which types of customer complaints are costing the company business
• figuring out how much time would be saved by removing a step in a process
• finding the mean weight of each finished product in a sample of 1,500
• discovering which suppliers deliver the best quality materials

Explanation:

Understand the purpose of a Pareto chart

A Pareto chart is a quality management tool used in Six Sigma and Process Improvement to identify the most significant factors in a dataset. It is based on the Pareto Principle (the 80/20 rule), which states that roughly 80% of problems or costs come from 20% of the causes. By plotting frequencies or costs in descending order, it helps teams prioritize which issues to address first to achieve the greatest impact.

Analyze the given options

• Determining which types of customer complaints are costing the company business: This involves categorizing complaints and measuring their financial impact to find the "vital few" categories causing the most damage. This is a classic application of a Pareto chart.
• Figuring out how much time would be saved by removing a step in a process: This is typically analyzed using value stream mapping or process cycle time analysis, not a Pareto chart.
• Finding the mean weight of each finished product in a sample of 1,500: This requires calculating descriptive statistics or plotting a histogram/control chart to analyze distribution and variation.
• Discovering which suppliers deliver the best quality materials: This is usually evaluated using supplier scorecards, scatter plots, or hypothesis testing rather than a Pareto chart.

Select the correct option

The first option directly aligns with the prioritization goal of a Pareto chart by identifying which specific complaint types have the highest financial impact.

Answer:

• Determining which types of customer complaints are costing the company business (Correct answer)
• Figuring out how much time would be saved by removing a step in a process
• Finding the mean weight of each finished product in a sample of 1,500
• Discovering which suppliers deliver the best quality materials
