Which technique is most widely used for distinguishing chronic from insignificant problems?

• A. Pareto diagram
• B. Flowchart
• C. Histogram
• D. Scatter diagram

Answer: (A)

Distinguishing chronic from insignificant problems comes down to prioritizing issues by how much they contribute to the total impact. The Pareto diagram does this by listing problem categories from most frequent (or most impactful) to least and showing a cumulative line. This makes it easy to see that a small number of problems—often the “vital few”—are responsible for the majority of effects, so you can target corrective actions where they’ll reduce the most issues over time. It’s based on the idea that a few causes drive most of the trouble, a practical application of focusing resources. A flowchart simply maps the steps in a process and doesn’t rank problems by frequency or impact. A histogram shows how a single variable is distributed, not which categories of problems are the most significant. A scatter diagram looks at relationships between two variables, not at prioritizing issues by how often they occur. So the Pareto diagram is the strongest tool for this purpose.
