- Clauses 8.2-8.4 and 9.1-10.2 connect change-triggered assessments, monitoring evidence, audit, management review, and corrective action.
ISO/IEC 42001 AI System Inventory Workflow
Create, approve, and maintain AI-system records from intake through lifecycle change and retirement, with accountable owners and links to impact, risk, control, supplier, and monitoring evidence.
Use the workflow to keep the AIMS scope and operating evidence current; do not treat inventory registration as proof that risk assessment or control operation is complete.

An should route new AI development, procurement, internal use, customer deployment, material change, and retirement through a common intake. ISO/IEC 42001:2023 does not prescribe a single inventory template; this workflow is Sorena's practical way to connect the standard's scope, resource, risk, impact, lifecycle, monitoring, and third-party requirements. It should reveal systems inside the approved AIMS boundary and escalate records whose ownership, purpose, evidence, or external dependencies are unclear.
Make the ISO/IEC 42001 inventory decision
Open or update an inventory record before an AI system is developed, procured, deployed, materially changed, transferred, or retired. Include internally built systems, third-party services with embedded AI, AI features added to an existing product, and AI used by staff where those activities can fall inside the AIMS boundary. The intake owner should identify the business purpose, intended use, prohibited or unsupported uses, lifecycle stage, system owner, users and affected parties, the organisation's lifecycle roles, and whether the activity sits within the approved AIMS scope.
Record the system as a complete operational arrangement, not only a model. Include relevant data, tooling, system and computing resources, human resources and competence, supplied services, customer or partner dependencies, deployment context, documentation, support, monitoring, and incident routes.
Inventory registration is an intake and traceability control. It does not by itself complete AI risk assessment, AI-system impact assessment, risk treatment, approval, or operating-control evidence.
- Trigger: new system or use, supplier onboarding, deployment, significant change, incident, transfer, or retirement. Define significant change in the AIMS procedure; ISO/IEC 42001 requires AI risk assessment at planned intervals or when significant changes are proposed or occur, and AI-system impact assessment at planned intervals or when significant changes are proposed.
- Minimum state: draft, under assessment, approved with conditions, approved, suspended, or retired.
- Evidence links: risk assessment, impact assessment, treatment plan, statement of applicability, supplier record, release decision, monitoring plan, incidents, and retirement record as applicable.
Records that show the workflow is working
A complete record lets a reviewer identify what the system does, where and by whom it is used, the lifecycle roles the organisation performs, the people or groups that may be affected, the resources and third parties it depends on, and the decisions that allow it to operate.
Assign field ownership. A product owner can maintain intended use and lifecycle status, while data, supplier, security, risk, impact, legal, and monitoring owners maintain the records within their authority. Preserve version history and links rather than copying stale evidence into the inventory.
- Identity and purpose: stable record ID, system name, description, owner, intended use, foreseeable misuse, users, affected parties, and deployment context.
- Lifecycle and resources: stage, organisation roles, model or tooling, data, infrastructure, people and competence, suppliers, customers, and responsibility allocations.
- Governance: AIMS scope status, objectives, risks, impacts, selected controls, approvals, monitoring criteria, incidents, changes, review date, and retention or retirement evidence.
Put the inventory workflow into operation
Capture owners, evidence, decisions, and review dates in one workflow record so AI governance controls and escalation points stay auditable over time.

Build a repeatable inventory workflow
At intake, create a draft record and classify the organisation's role, intended use, scope status, lifecycle stage, and dependencies. Assign the system owner and specialist field owners. If the activity is outside the approved AIMS boundary, record the exclusion rationale, boundary interface, and owner instead of silently dropping the record. Route an in-scope record to the risk and impact processes before approval when the organisation's criteria require them.
An approval authority should decide whether the system may proceed, proceed with conditions, remain blocked, or be retired. Record the basis, conditions, evidence gaps, expiry or review date, and the event triggers that reopen the decision.
- Reject or hold a record that lacks an accountable owner, defined intended use, AIMS scope decision, or required assessment; record the blocker, decision owner, due date, and condition for reopening.
- Send supplier and customer dependencies to the owners who can allocate responsibilities and obtain missing information.
- Send approved records into release, monitoring, incident, change, and retirement workflows with the same stable inventory ID.
Common mistakes that make the workflow hard to audit
The workflow fails when discovery depends only on voluntary registration, when one team owns every field in name only, or when a model catalogue omits the surrounding service, data, people, deployment context, and external dependencies. Reconcile intake with procurement, expense, identity-access, architecture, product, supplier, and support records so unregistered use can be investigated.
Do not copy legal roles or risk labels into the record without the facts and source that support them. ISO/IEC 42001 structures the management system; applicable law, contracts, and sector rules can create separate inventory fields, classifications, or approvals.
- Do not mark a record approved because a supplier says its model is certified.
- Do not overwrite prior states; preserve what changed, who decided, and which linked assessments were reopened.
- Do not treat retirement as deletion; record shutdown, access removal, data and record disposition, residual obligations, and the retention basis.
Review and improve the workflow over time
Review records at planned intervals and when intended use, deployment context, data, model or tooling, supplier, customer allocation, performance, affected parties, legal requirements, or lifecycle state changes. Define 'significant change' in the organisation's procedures so teams know when risk and impact assessments must be repeated.
When a system is retired, close active access and support, preserve required documented information, update the AIMS scope and dependencies where necessary, and retain a final decision record.
- Reconcile the inventory against procurement, architecture, product, access, and supplier records to find unregistered systems.
- Track overdue reviews, missing owners, blocked approvals, and unsupported dependencies as measurable inventory-quality signals.
- Feed material trends, incidents, nonconformities, and resource gaps into internal audit, corrective action, and management review.
