Others
Occam's Razor: a problem-solving principle attributed to the 14th-century English philosopher William of Ockham. It posits that when faced with competing hypotheses or explanations for a phenomenon, the simplest one - one that makes the fewest assumptions - should be preferred. In other words, "entities should not be multiplied beyond necessity.”
Pareto Principle: Also known as the 80/20 Rule, is a concept in economics and productivity that suggests that roughly 80% of effects come from 20% of the causes. Named after the Italian economist Vilfredo Pareto, who observed that 80% of land in Italy was owned by 20% of the population, this principle can be applied to various fields, including business, software development, and time management.
Parkinson’s Law: A principle formulated by British naval historian Cyril Northcote Parkinson, which states that "work expands to fill the time available for its completion." This observation highlights how the amount of time allotted for a task can influence the complexity and duration of that task, regardless of its actual difficulty.
