A Pareto chart is a bar graph. For example a financial approach (improvement of profits) will focus on how the score relates to what costs are involved with solving these problems. In essence, the problem-solver estimates the benefit delivered by each action, then selects a number of the most effective actions that deliver a total benefit reasonably close to the maximal possible one.

The Pareto Analysis (known as Pareto Diagram or Chart) was designed by Vilfredo Pareto, an Italian engineer who made several important contributions to economic theory. Using the information from step 4, an action plan can be drawn up in which performance improvement actions can be formulated. The data can be converted into a graph called a Pareto Analysis Diagram. The higher the score, the greater the impact. Lorenz developed graphs to illustrate it. The company could run sales campaigns for its clothing to boost new sales and offer rebates or discounts to dissatisfied customers from the glitch to win the trust of existing customers. A few of the 80/20 rule examples from daily practice which are often correct are: The principle of the Pareto Analysis is based on the Zipf distribution (pattern in linguistics and a discrete probability distribution with parameters λ and N).
