Explanation

The Pareto Principle (Pareto's Law / the 80/20 rule), named after economist Vilfredo Pareto, states that roughly 80% of outcomes come from 20% of causes. In Agile, this supports prioritizing the small subset of features that deliver the most customer value. Parkinson's Law states that work expands to fill the time available. Moore's Law relates to the doubling of transistor density roughly every two years. Jevon's Paradox describes how efficiency improvements can paradoxically increase total resource consumption.
