80/20 Rule

Noun · Hacker Culture

Definitions

  1. A heuristic based on the Pareto principle suggesting that a small portion of causes often drives a large portion of outcomes, commonly framed as eighty percent coming from twenty percent. In tech work, it is often used to justify prioritizing the highest-leverage tasks first.

    In plain English: The idea that a small number of inputs often produces most of the results.

    Example: "They applied the 80/20 rule to bug triage and focused on the handful of integration issues causing most of the support tickets."
