A project manager aims to improve product quality by addressing the most common causes of defects first. Which of the following tools should the project manager use to identify and prioritize these defects based on their frequency?
Scatter diagram
Pareto chart
Flowchart
Run chart
A Pareto chart is a bar graph that displays the causes of defects in descending order of frequency. This allows the project manager to identify which issues are most common and prioritize them for corrective action. A run chart shows data trends over time but doesn't rank causes by frequency. A flowchart maps out the steps in a process to identify potential inefficiencies, not the frequency of defects. A scatter diagram displays the relationship between two variables but doesn't help in prioritizing defect causes based on how often they occur.
