Das Pareto-Prinzip - Die 20/80 Regel

The video explains the 80/20 rule, also known as the Pareto principle, which suggests that 20% of causes often lead to 80% of results. It was discovered by economist Wilfredo Pareto, who observed this pattern in his garden and in land ownership in Italy. The principle is widely applied in business, safety, and software development to prioritize efforts. However, Pareto cautioned against over-reliance on the rule, as people tend to rationalize their actions with theories. The video encourages viewers to consider where the rule applies and where deeper analysis is needed.
