Frameworks

Proofwork.

One idea holds these frameworks together: AI only counts when you can prove it — in the work, and in the P&L. The Ladder is where a firm sits. The Four Numbers are what proof is measured in. The Production Gap is where proof dies before reaching the books.

  1. The Delivery Model Ladder

    A four-stage model for how service firms move from human-delivered to AI-native delivery. Each stage is defined by economic signature, not tooling.

  2. The Four Numbers

    AI does not save a service firm time. It changes four numbers: cost to deliver, retention, margin, and revenue per person. Every implementation succeeds or fails on which of them it moves.

  3. The Production Gap

    The eleven ways AI implementations die inside service firms, before they ever touch the P&L.
