Partially by: #notebook/ai/google/bard ## Description The 80/20 rule, also known as the Pareto Principle, suggests that roughly s80% of consequences come from 20% of causes. This principle highlights the uneven distribution of effects across contributing factors, encouraging efforts to be focused on the "vital few". ## Examples - 80% of a company's profits may come from 20% of its customers. - 80% of website traffic might come from 20% of its pages. - 80% of bugs in software often cause 20% of crashes. - 80% of learning gains in a language course might come from 20% of the studied material. ## Related concepts and principles - [[Power-law distributions]] - [[Minimum effective dose]] - [[Opportunity cost]] - [[Critical Path Method]] ## Related methods - **[[Pareto analysis]]:** Identifies the "vital few" by analysing contributing factors and their corresponding effects. - **[[Eisenhower Matrix]]:** Prioritizes tasks based on urgency and importance, aligning with the 80/20 principle. - **[[ABC Analysis]]:** Categorizes inventory items based on their value and impact, similar to prioritizing "vital few" resources. - **[[MECE principle]]:** Ensures a comprehensive and mutually exclusive analysis, helping identify true "vital few" factors. ## Related content and sources
