Pareto Analysis


Topic: Process Improvement | Resource type: Video

The Pareto chart, originally developed by the Italian Sociologist Vilfredo Pareto, displays a rank ordered and decreasing array of factors by frequency and the cumulative percentage of overall cases. Robert Lloyd, PhD, Executive Director of Performance Improvement at the Institute for Healthcare Improvement, explains how Pareto charts are used to distinguish the “vital few” factors which make the greatest contribution to an outcome from the “trivial many” which have less collective impact.
