Pareto Diagram

Concept of Pareto Chart is a tool used to prioritize the problems or causes that generate them. Pareto's name was given by Dr. Juran in honor of the Italian economist Vilfredo Pareto (1848 – 1923) who conducted a study on the distribution of wealth, which found that the minority of the population owned most of the wealth and the majority of the population had the smallest share of wealth. Dr. Juran applied this concept to the quality, resulting in what is now known as the 80/20 rule. According to this concept, if you have a problem with many causes, we can say that 20% of cases resolve the problem 80% and 80% of cases only solve 20% of the problem.

We recommend using Pareto diagram: To identify opportunities for improvement To identify a product or service for the analysis of quality improvement. When there is a need to draw attention to the problems or causes in a systematic way. To analyze the different groupings of data. In seeking the root causes problems and prioritize solutions to evaluate the results of a process performed cambes comparing successive diagrams obtained at different times (before and after) when the data are divided into classes when the rank of each category is important for easily communicate with other members of the organization of the findings on causes, effects and error costs. The general purposes of the Pareto diagram: Analyze the causes Planning Study results continuous improvement The Pareto chart is a simple but powerful tool to enable visually identify a single revision minorities vital feature that is important to pay attention and So use all the resources necessary to carry out improvement action without wasting effort and that the analysis discarding the majority trivial.
