The 80/20 Principle

A lens for leverage: use Pareto analysis to prioritize platform and product bets, concentrating talent and time where usage and value are already spiking.

Richard Koch Crown Business, 1998 ISBN 9780385491747
Who This Is For: Engineering managers, platform teams, and product leaders who need ruthless prioritization.

80/20 thinking turns prioritization into a data-backed habit: concentrate on the critical few where value already accumulates.

Who This Is For

Leaders who must allocate scarce engineering capacity for maximum impact—platform, product, and EMs.

Key Takeaways

  • A minority of services, customers, or features create the majority of outcomes.
  • Cut or automate the long tail to reclaim engineering time.
  • Rank by usage, incidents, and value—not who shouts loudest.
  • Sequence related improvements around high-leverage areas to compound gains.
  • Recalculate quarterly; the vital few shift as systems evolve.

I’m Derek — software engineer, infrastructure nerd, and chronic tinkerer. 10+ years building payment platforms, production systems, and the kind of infrastructure that has to work at 3am whether I’m awake or not. When I’m not at my day job, I’m running local LLMs on dual 3090s, 3D printing things my wife didn’t ask for, and writing about all of it here. Topics range from code to infrastructure, AI, and whatever I broke this week.
