How Pareto analysis works
Pareto analysis ranks categories by contribution, adds up their shares, and stops at the point where a threshold — usually 80% — is crossed. Everything above the line is the vital few; everything below is the trivial many. The value is not the chart, it is the decision: work on the vital few first.
