Part 5 of the Corporate Assist Data and AI Governance Series
Effective AI governance depends on Boards receiving clear information about the organisation’s material AI use, responsibilities, controls, evidence gaps and outstanding actions.
An AI inventory provides visibility over systems, purposes, suppliers and responsible owners. It is an important foundation, but it does not provide Board assurance on its own.
The next stage is to bring together the work completed by the organisation’s specialist functions and convert it into proportionate information for senior management and the Board.
Effective board oversight of AI
The Board does not need a list of every AI-enabled system or copies of every supporting document. It needs sufficient information to understand:
Where the organisation has material AI exposure
Who is accountable
Which risks and opportunities are significant
Whether relevant legal, regulatory and internal requirements have been assessed
Whether material controls operate effectively
Whether evidence supports the assurance provided
What incidents, exceptions or gaps remain
Which actions are overdue
What decisions or support are required
The level of detail should reflect the organisation’s activities, the significance of its AI use and the potential effect on customers, employees or other individuals.
Board reporting should enable effective oversight and challenge. It should not overwhelm the Board with operational detail or present a simplified position that obscures material gaps and uncertainty.
Bringing information together
Evidence about AI governance is often held across several functions.
Compliance may hold monitoring information, Data Protection may hold impact assessments and Procurement may hold supplier records. Information Security may hold technical assurance, while Legal holds applicability or contractual advice. Operational teams may retain system approvals and evidence of human review.
Each function may have completed its part of the work, but the organisation still needs to understand the overall position.
The relevant conclusions, evidence, gaps and actions therefore need to be brought together. This enables management and the Board to understand how the separate assessments and controls support the organisation’s overall governance arrangements.
Supporting assurance with evidence
Management may provide assurance that an AI system is appropriately governed or that relevant controls are in place.
The governance record should identify:
Who provides the assurance
What conclusion has been reached
What evidence supports that conclusion
Who has reviewed the evidence
What limitations or qualifications apply
What actions remain outstanding
When the position will next be reviewed
This does not mean sending every supporting document to the Board. It means ensuring that the assurance can be explained and substantiated if challenged.
A statement that an AI system is compliant, low risk, or appropriately controlled provides limited assurance unless the organisation can explain how it reached that conclusion.
Creating an AI evidence register
An AI inventory records where and how the organisation uses AI. An AI evidence register serves a different but related purpose: it identifies the assessments, approvals, controls, and other evidence that support the governance of each material AI system or use.
The inventory answers, “What AI are we using?” The evidence register answers, “What evidence supports the assurance we provide about it?”
Each system in the AI inventory can be given a unique reference. The same reference can then be used within the evidence register to connect that system to its supporting information.
The evidence register may refer to:
System approvals
Risk and impact assessments
Supplier questionnaires
Contractual documentation
Legal or technical advice
Policies and procedures
Employee guidance
Training and AI literacy records
Human-review records
Monitoring results
Transparency notices
Incident and exception records
Committee papers and minutes
Evidence supporting completed actions
The register does not need to duplicate the underlying documents. It can show where each item is held, who owns it, what system or activity it relates to, what period it covers and when it requires review.
This creates a clearer route between the assurance reported to the Board and the supporting evidence held within the organisation.
Managing AI governance actions
Each material action should include:
A clear description of the required outcome
A responsible owner
A target date
Relevant dependencies
The evidence required for closure
Any required specialist review or approval
Actions should not be closed simply because somebody has completed an activity.
For example, obtaining a supplier questionnaire does not necessarily complete an action concerning supplier assurance. The appropriate specialist may still need to assess whether the response is sufficient and whether any gaps, risks or contractual issues remain.
Action closure should reflect whether the intended outcome has been achieved and whether appropriate evidence supports that conclusion.
Overdue or repeatedly extended actions should be visible within management and Board reporting where they create a material governance, compliance or operational risk.
Reporting exceptions and uncertainty
Good AI governance reporting should not create a false impression of certainty.
Material exceptions may include:
Unapproved or informal AI use
Missing supplier information
Incomplete legal, data protection or technical assessments
Failure to follow an approval process
Insufficient evidence of human review
An incident involving confidential or personal information
A system being used for a purpose that was not originally approved
Uncertainty about whether a legal or regulatory requirement applies
The report should identify where the organisation’s position depends on further legal, technical or supplier input.
This enables the Board or relevant committee to understand the actual position, challenge the proposed response and monitor whether the matter is resolved.
An unresolved question does not necessarily indicate poor governance. Failing to identify, record and manage it does.
What should an AI governance report include?
A proportionate AI governance report may cover:
The organisation’s most significant AI uses
Material changes since the previous report
Responsible senior owners
Principal risks and opportunities
Relevant legal and regulatory developments
The status of key controls
Supplier dependencies
Incidents and exceptions
Gaps in evidence or assurance
Overdue or high-priority actions
Decisions, resources or support required
Planned reviews and next steps
Part 4 of this series considered the EU AI Act and the circumstances in which its requirements may affect UK organisations.
The report should distinguish between information provided for awareness and matters requiring challenge, approval or a decision.
It should also make clear whether the information covers the whole organisation or only particular systems, activities or functions. This prevents a limited assessment from being presented as organisation-wide assurance.
Continuing assurance
AI systems and supplier services can change quickly. New functions may be added, an approved use may expand, or a supplier may change how it processes information.
The governance arrangements should establish:
How frequently the AI inventory is reviewed
Which changes require reassessment or approval
How supplier changes are identified and monitored
How incidents and exceptions are escalated
What information is reported between scheduled reporting cycles
When management or Board assurance needs to be refreshed
The review cycle should reflect the organisation’s actual exposure. A fixed annual review may not be sufficient for a material system that changes frequently or significantly affects customers, employees or regulated activities.
Continuing assurance depends on maintaining the connection between the AI inventory, specialist assessments, controls, evidence, actions and Board reporting.
Supporting AI governance and Board reporting
Your organisation may already have the relevant Legal, Compliance, Data Protection, Risk and technical expertise. The challenge is often finding enough capacity to gather different contributions, resolve inconsistencies, maintain evidence and actions, and turn the overall position into clear reporting.
Corporate Assist can support a defined AI governance and Board reporting project by coordinating contributions, consolidating information, maintaining evidence and action records, following up outstanding matters and preparing reports for management, Boards or committees.
Your Legal, Compliance, Data Protection, Risk and technical specialists retain responsibility for their assessments and conclusions. However, Corporate Assist can ensure that the wider project remains properly coordinated, organised and focused on achieving a clear outcome.
If you need a trusted resource to support a defined governance or compliance project, please get in touch to discuss your requirements
