![]() ![]() Juran, who extended this theory into the business world. It was the “ Father of Quality Management” Dr. He then investigated different industries and found that 80% of production typically came from only 20% of companies.Īlthough he researched and wrote papers on this theory, he never took it further than wealth and prosperity. He discovered that around 80% of the land in Italy was owned by 20% of the population. This observation led him to think about uneven distribution, and where better to start with that concept than by looking at wealth. Now, most of us might’ve thought “ Hah! Well, would you look at that!” and carried on with our daily lives. He noticed that roughly 20% of his pea plants seemed to generate around 80% of the peas. Pareto, a philosopher, economist, and keen gardener, had an epiphany one day, while out picking peas. The Pareto chart takes its name from a 19th-century Italian called Vilfredo Pareto, and as we touched on earlier, the concept is based on the 80/20 rule. This is the story behind where the Pareto chart came from. This leads me, quite nicely, to talk about where the Pareto chart came from. While we’re on the subject of the 80/20 rule, for those of you who don’t know, the 80/20 rule is also referred to as the ‘Pareto principle’. “ The significant few things will generally make up 80% of the whole, while the trivial many will make up about 20%” – Pareto Diagram, PQ Systems The Pareto chart displays the few, most significant defects, that make up most of the overall problem.īy ordering the bars from the largest to the smallest, a Pareto chart helps you to visualize which factors comprise the 20% that are the vital few, and which factors make up the trivial many. The 80/20 rule states that 80% of the results are determined by 20% of the causes. That’s because the Pareto chart is a visual representation of the 80/20 rule. It’s a tool that’s been used for decades by problem solvers to separate the vital few factors from the trivial many and prioritize actions.įor those that are familiar with the 80/20 rule, the phrase ‘ separating the vital few from the trivial many’ may have rung a few bells? The Pareto chart theory suggests that if the organization prioritized training and increasing pay, they would see the biggest improvement in customer service. With a quick glance, we can instantly see that a lack of training and inadequate pay cause the highest number of customer service complaints. Take this Pareto chart below as an example. Focusing its efforts on reducing the largest bars in the chart, will do more for overall improvement than reducing the smaller ones. Well, it’s so simple it almost sounds silly.īy graphically separating the aspects of a problem, an organization can instantly see where to direct its improvement efforts. How does a humble bar chart do that?! I hear you ask. In other words, it’s a vital quality management tool.Ī Pareto chart enables organizations to make decisions on where to focus their efforts so they get as much bang for their buck as possible. This bar chart is used by organizations, in almost every industry, for root cause analysis. However, this simple little bar chart is different from the bar charts you created when you were six. The bigger bars on the left are more important than the smaller bars on the right. Well, keep hold of that memory as it will come in handy for this post.īecause the Pareto chart is, essentially, a plain old bar graph.Ī Pareto chart, in its simplest form, is a bar chart that arranges the bars from largest to smallest, from left to right. When it was working through straightforward sums and creating graphs? The ‘fun’ stuff. ![]() Remember math lessons as a kid? I mean before it began to get tricky with trigonometry and algebra. I may have googled “ basketball terms” for that sentence… what I’m basically saying is C’mon you lot! Let’s go! So, my cagers, let’s take it to the hole!
