Paretoanalyysi

Pareto analysis, also known as the 80/20 rule, is a decision-making technique that focuses on identifying the most important factors contributing to a problem or opportunity. It was developed by Vilfredo Pareto, an Italian economist, who observed that 80% of the land in Italy was owned by 20% of the population. This principle suggests that a small number of factors often account for the majority of outcomes or results.

The technique involves ranking factors in order of their impact and then categorizing them into two groups: the vital few and the trivial many. The vital few are the most significant factors that contribute to the majority of the results, while the trivial many are the less important factors that contribute to a smaller portion of the results. By focusing on the vital few, decision-makers can allocate resources more effectively and achieve better outcomes.

Pareto analysis is widely used in various fields, including business, project management, and quality control. It helps prioritize tasks, allocate resources, and improve efficiency. However, it is important to note that the 80/20 rule is not a universal truth and may not apply to all situations. The effectiveness of Pareto analysis depends on the specific context and the accuracy of the data used for analysis.
