What is a Pareto Chart?
A Pareto Chart is a bar graph that represents the frequency or impact of problems in a descending order. Named after the Italian economist Vilfredo Pareto, who observed that 80% of effects come from 20% of the causes, this chart is a visual representation of the vital few versus the trivial many. By identifying the most significant issues, businesses can allocate resources more efficiently, leading to improved performance and higher customer satisfaction.
