PIRXEY / Mission Brief
✦ ✦ ✦A Pirxey field briefing for product managers

10× isn't a constant.
It's a function of project size.

AI assistance compounds beautifully on small, greenfield work — and decays predictably as codebases mature, processes thicken, and humans must coordinate. Below is the model we use to set realistic expectations with you, before a single line of code is written.

Drag the slider. Watch the boost decay.

Move from a weekend MVP to a 1M+ LOC enterprise system. The X-factor isn't a marketing number — it's AI efficiency × Human factor, and both terms shrink as complexity grows.

AI efficiencyBase AI efficiency retained at each complexity step; the displayed value is this percentage compounded by the current slider step.
Human factorBase human/process efficiency retained at each complexity step; set it to 100% to simulate eliminating human friction.
Final efficiencyThe realized boost after geometric compounding: AIⁿ × Humanⁿ, translated into the X-factor.

◢◣ Why · the six forces

What's actually shrinking the boost?

Six measurable forces — each backed by 2025–2026 research. Together they explain the curve you just dragged through.
