Pareto diagram in plain English
A bakery that only tastes cookies after they burn is paying the expensive kind of lesson. Catching problems in the recipe is cheaper than refunding customers. Pareto diagram is about where in that chain you look, measure, and fix. Hold onto this precise job description: A histogram ordered by frequency of occurrence with a cumulative percentage line, used to identify the vital few causes producing most of the effect. On a stem, name whether Pareto diagram is about timing, ownership, measurement, or delivery style — then eliminate the answer that borrows a cousin concept from the wrong phase.
