Model governance:
every step, its own model.

Step 2, claims intake. Model chosen for long policy documents and handwritten forms, because it reads the whole file before it drafts. Signed off by the Head of Claims.

Step 4, renewals. A reasoning model, used only where a rate change needs a reason; everything else runs on a smaller one. Signed off by underwriting.

Step 1, document review. Model chosen for contracts read clause by clause against your standard wording. Never trained on your data. Signed off by counsel.

Step 3, reconciliation. A small, fast model that matches every entry to its record. Anything that does not line up goes to a person. Signed off by finance.

Step 2, estimating. Model chosen to apply your estimators' own rules to drawings and quantities. Changed only under change control. Signed off by preconstruction.

Step 1, site selection. Model chosen to read satellite imagery, well records and permits together. Signed off by the head of exploration.

Step 5, correspondence. Model chosen to write in your house style. Every letter is held for a person to approve before it leaves.

Step 1, exposure. Model chosen for exact figures across currencies and policies, rerun every morning before the desk opens. Signed off by the Head of Underwriting.

Step 6, reporting. Model chosen to trace every figure back to the record it came from. A change to it goes through change control first.
