Missio definition
An AI system inventory is the organization's governed record of active, proposed, acquired, embedded, and retired AI use. A useful inventory names the business purpose, accountable owner, users, data, model or vendor dependencies, deployment status, decision impact, risk tier, controls, monitoring, and supporting evidence.
The inventory is not a spreadsheet assembled for an audit and then forgotten. It is the control plane for portfolio decisions: what may proceed, what requires additional review, what changed, and what should be paused or retired.
Scope note
This definition supports executive and operating decisions. Applicable law, contracts, sector rules, and system context may require a narrower definition.
