# Pareto Principle (80/20) ## Concept In most systems, ~80% of the outcome comes from ~20% of the inputs. Strategy consultants use this constantly: figure out which 20% of customers, products, channels, or root causes drive the lion's share of impact, and ignore the rest until later. The discipline isn't naming the vital 20%. It's having the spine to **explicitly deprioritize the 80%**. If everything is important, nothing is. ## Required output format Two parts, in this order: 1. A Markdown blockquote naming the vital 20%. 2. A bulleted list under "Actively deprioritized (the 80%):" naming what's being set aside. ```markdown > **The vital 20%:** [Specific factors/segments/causes that drive the majority of impact.] **Actively deprioritized (the 80%):** - Item 1 - Item 2 ``` ## Defaults & flex points | Default | When to flex | |---|---| | 1–4 items in the vital 20% | If the 80/20 genuinely points to one thing, use one. Don't pad. | | 5–10 items in the deprioritized list | List enough to make the deprioritization visible — but if there are only 3 real alternatives, list 3. | | Specificity in the vital 20% | Don't flex — "our top customers" is too vague. Name them. | | Explicit deprioritization | Don't flex — implicit deprioritization is no deprioritization. | **The hardest discipline:** writing down something that genuinely matters into the deprioritized list. If your 80% list is full of things that don't matter, you haven't really prioritized. Real Pareto says: "Yes,
