Prompt

80% of outputs come from 20% of inputs. This is not a rule of thumb — it is a power law that governs most systems. Application: 1. Identify: list all inputs for [your domain] (customers, features, tasks, employees). 2. Measure: which 20% produce 80% of the value? 3. Amplify: double down on the vital few. 4. Audit: which 80% of inputs produce only 20% of value? Reduce or eliminate them. Recursive application: within the top 20%, find the top 20% again. That 4% produces 64% of total results. In business: 20% of customers drive 80% of revenue. 20% of bugs cause 80% of crashes. 20% of features drive 80% of usage. The discipline is not in finding the 80/20 — it is in having the courage to ignore the 80%.
