A model inventory is a comprehensive, maintained record of all models in use across an organisation, capturing ownership, purpose, inputs, methodology, validation status, risk tier and lifecycle stage.
In practiceSupervisory guidance SR 11-7 treats a complete and current model inventory as a foundational element of model risk management. Without it, governance, validation and incident response cannot be applied consistently. Practitioners often discover that spreadsheets, business rules, vendor scoring engines and embedded AI features are missing from the inventory and therefore from oversight. With the EU AI Act and SR 11-7 both in scope for many institutions, the inventory is also the single source of truth that links models to risk classifications and to evidence packs.
A bank consolidates its model inventory into a single register covering credit, market, operational and AI models, with each entry linked to its validation report, risk tier, owner and the regulatory regimes that apply to it.
