AI Governance and Human-in-the-Loop Reviews for Financial Services

AI governance is a decision and accountability discipline

AI governance defines how an organisation evaluates, deploys, uses, monitors and oversees AI systems. For financial services, it needs to connect business accountability with model risk, operational risk, technology risk, information security, data governance and applicable compliance obligations. A policy document alone does not demonstrate that these responsibilities are exercised.

The starting point is a specific use case: what does the system do, who uses its output, which decisions can it influence and what harm could result from an unsuitable outcome? An internal summarisation assistant and a system influencing a customer-facing decision may need very different review and control arrangements.

What human-in-the-loop means in practice

A human-in-the-loop process places a person within a defined decision sequence. The person may review a recommendation, question its basis, request additional evidence or decide whether it should proceed. The value comes from the quality and authority of the review, not simply from having a human click an approval button.

A human-on-the-loop arrangement generally involves monitoring a system with the ability to intervene rather than reviewing each output before it is used. Neither label proves that oversight is effective. Define the actual decision rights, intervention points, response times and evidence requirements for the use case.

• Context: can the reviewer understand the purpose, intended use and limitations of the output?
• Evidence: are relevant inputs, assumptions and validation or testing results available?
• Competence: does the reviewer have the expertise and time to challenge the proposal?
• Authority: can a concern change the decision, trigger escalation or prevent inappropriate reliance?
• Accountability: is there a named owner for the final decision and any residual risk?

Connect oversight to the existing GRC programme

AI should not sit outside the organisation’s governance, risk and compliance processes. Map the use case to existing policies, risk ownership, control testing, incident management and change management arrangements. Identify where additional expertise or controls are needed instead of duplicating every existing process.

For a bank, insurer, asset manager or fintech, the review might involve business owners, compliance, model validation, operational risk, technology, information security or independent assurance. The appropriate participants depend on the system and the organisation’s operating model. A consistent questionnaire can help structure the discussion, but reviewers must still exercise judgement.

Questions for technology risk and compliance reviewers

• What data enters the system, where does it go and which privacy, confidentiality or security constraints apply?
• How are access, configuration changes, software dependencies and third-party services controlled?
• What testing supports the intended use, and which limitations remain after testing?
• What is the consequence of an inaccurate, incomplete, biased or misleading output?
• Which business decisions require human review, and how will that requirement be enforced?
• What monitoring or incident signals trigger reassessment, escalation or withdrawal from use?
• Which obligations apply to the use case, jurisdiction and the organisation’s role as provider, deployer or user?

Do not treat a general AI checklist as a determination of legal applicability. For example, the European Commission’s AI regulatory framework distinguishes system uses and responsibilities. Obtain appropriate specialist advice where required, and verify the current rules and transition arrangements for the specific deployment.

Record a credible challenge, not just an approval

A useful review record connects the proposed decision to the concern, supporting evidence, management response and final rationale. If an AI-generated recommendation is accepted despite a limitation, the record should explain who accepted the residual risk, under which conditions and what follow-up is required.

Consider a proposal to change a model monitoring threshold. A reviewer can ask how the threshold was selected, whether testing covers relevant customer or transaction groups and what happens when a monitoring signal is triggered. If more evidence is needed, the record should retain that request and the response. Approval alone does not explain why the concern was resolved.

This is the same credible challenge discipline used across financial services GRC, risk and compliance reviews, applied to AI-influenced work.

Separate review records from technical enforcement

A review workspace can organise questions, evidence references and decision rationale. It should not be assumed to control an external AI system unless the connection and enforcement behaviour have been implemented and tested. A recorded pause or objection is not automatically an execution block in another application.

For an agentic workflow, define what is sent to the review process, which actions require human permission, how a return or escalation is handled, and what happens if the integration is unavailable. Connecting an external agent, an Appian-based process or an existing GRC platform requires a scoped integration. The integration must be tested independently of the review interface.

A buyer’s trial checklist

1. Select a representative, non-sensitive AI or technology proposal and define the decision owner.
2. Ask risk, compliance and technology reviewers to identify the questions they need answered.
3. Work through the questions, evidence references, responses and rationale with real roles.
4. Verify which records persist and which reporting, retention or integration requirements remain to be delivered.
5. Test the human handoff separately from any external workflow enforcement.
6. Assess security, privacy and contractual requirements before relying on the process in production.
