Paretoelemzéssel

Paretoelemzés, often referred to as the Pareto principle or the 80/20 rule, is a principle that states that for many outcomes, roughly 80% of the effects come from 20% of the causes. This principle was first observed by Italian economist Vilfredo Pareto in 1906, who noticed that 80% of the land in Italy was owned by 20% of the population.

The Pareto principle is not a strict mathematical law but rather an observation that can be applied to a wide range of situations. It suggests that a significant majority of results are produced by a minority of efforts or inputs. This concept has been widely adopted in various fields, including business, economics, quality control, and time management.

In business, for example, a company might find that 80% of its sales come from 20% of its customers, or that 80% of customer complaints relate to 20% of its products or services. In time management, individuals might discover that 80% of their accomplishments are achieved by focusing on 20% of their tasks.

The value of Paretoelemzés lies in its ability to help prioritize efforts. By identifying the vital few causes that contribute to the majority of outcomes, individuals and organizations can focus their resources and attention more effectively. This can lead to increased efficiency, improved productivity, and better decision-making by concentrating on the most impactful areas. While the 80/20 ratio is a common approximation, the core idea is the uneven distribution of causes and effects, where a small number of factors have a disproportionately large impact.
