Which tool helps prioritize problems by frequency of occurrence?

• A. Check Sheets
• B. Pareto Analysis
• C. Cause & Effect Diagrams
• D. Flow Diagram

Answer: (B)

Prioritizing improvements by how often problems occur focuses your efforts on the issues that drive most of the trouble. Pareto Analysis does exactly that: it collects data on each problem’s frequency, ranks problems from the most frequent to the least, and usually presents the results in a Pareto chart. The chart makes the “vital few” problems stand out, showing which issues account for the majority of occurrences so you can tackle them first. In practice, you’d often start with data collection using a check sheet to tally each problem, then run the Pareto analysis to see which ones rise to the top. The other tools serve different roles: a check sheet is for data gathering, a cause-and-effect diagram maps potential root causes, and a flow diagram lays out the steps of a process.
