Executive summary
Executives face pressure to innovate faster and demonstrate a return on AI investment.
When agents can release payments, change records or make commitments to customers, the organisation remains accountable for the consequences. Weak controls can expose the organisation to financial loss and harm the people it serves. Agents may repeat an error across many transactions before anyone intervenes. Boards and executives need assurance that expected business outcomes are being achieved, risks remain within agreed limits and controls work in practice.
Testing before agents go live is necessary, but it cannot show whether later work keeps meeting expectations. This paper sets out a method for continuous assurance: checking AI-enabled work during operation against intended outcomes and agreed requirements, and using the evidence to decide whether the work should continue, expand, be restricted or stop. It builds on existing management, risk and control responsibilities.
Leaders base those decisions on reports, prepared by management and, where required, by an independent reviewer. Reports should show the work and period covered, what was checked, what failed and what remains unchecked or unresolved. They should identify who assessed the work and the limitations of the conclusion. Management's own checks remain distinct from independent assurance.
The business case and budget should include the people needed to review and correct agent work, with the expertise, authority and time to challenge it and act on problems.
Start with one business process where agents are already in production. Ask the business process owner to answer the questions in Questions to ask management (C2) using recent results and supporting evidence. Use the review to decide whether to maintain, expand or restrict agent authority, and what needs to improve.
Five questions for reviewing agent work
- Was the action authorised?
- Did the safeguards work?
- Was the intended outcome achieved?
- What remains unresolved, and what risk remains?
- What evidence supports the answers?
An authorised action can still produce the wrong outcome, and an apparently good outcome does not establish whether safeguards worked. Use the answers to decide whether the work should continue, expand, be restricted or stop.
Scope and further reading
The method draws on regulation, standards and iTmethods' engineering and client experience. Where it draws on our own work, it describes what that work is designed to do.
This edition reflects regulations, standards and research available in September 2026. Check the current version of any instrument before relying on it.
Using laws and standards
References to laws and standards show where the method can support an obligation or established practice; they do not establish compliance or conformance. Mapping any of it to your own control framework is joint work with your compliance function and counsel, and whether evidence is sufficient for a purpose is a judgment for your own risk, compliance and audit experts.
The main paper covers the decisions and evidence leaders need. For an executive review, start with the executive summary, the five questions and Questions to ask management (C2). Appendix 1 provides control and operating guidance for delivery, risk and audit teams. Appendix 2 covers regulations and standards; the glossary and sources follow.
Part AApplying controls to agent work
Apply existing controls to the work agents do, and extend them where agents change how that work is done.
Running example: refunds and fee corrections
At a retail financial-services firm, AI agents handle about 6,000 refund and fee-correction requests a week. They triage each request, decide eligibility, issue refunds of up to $250 on their own, update the customer's record and reply. Larger refunds go to four approvers. The firm and its figures are fictional.
A1. Oversight before and after agents go live
Management defines the intended outcomes, the risk limits that put the board's risk appetite into practice, and accountability for each AI-enabled process. The people responsible need evidence that the work meets those expectations and authority to respond when it does not.
| What needs attention | Management response |
|---|---|
| Outputs and chosen actions can vary from case to case | Test representative scenarios, and check whether the business result meets agreed requirements. |
| Behaviour can change when models, instructions, tools, data or suppliers change | Identify material changes and reassess the affected controls and permitted scope. |
| Agents can take many consequential actions between reviews | Limit cumulative exposure, and define when systems must hold or restrict work. |
| An agent's self-assessment should not be the only check | Check the work against rules, source records or other evidence. |
| As agents take the routine cases, reviewers may receive more ambiguous, disputed or consequential cases | Plan and budget the people, skills and time to review, correct and escalate that work. |
Testing before deployment shows how the system behaved under the conditions tested. Oversight during operation examines the work performed since, including whether the outcome was achieved and whether the controls worked.
The plan-do-check-act cycle in Figure 2 connects these responsibilities before and after agents go live.
Plan
Set expectations
Define the intended outcomes, limits on agent authority, accountable owners and the resources and controls needed.
Do
Put the plan into practice
Build, test and operate the process within its approved scope, with the agreed controls and human oversight in place.
Check
Review the evidence
Assess business results, costs and control performance against expectations. Identify what failed, what was not checked and what remains unresolved.
Act
Decide what changes
Correct problems and decide whether to maintain, expand, restrict or stop the work. Update the controls, resources or permitted scope where needed.
Use findings to update the plan
Checks run during operation as well as at scheduled reviews. Findings may require immediate intervention or changes to the wider plan. Appendix 1.1 explains how this management cycle connects to the detailed workflow and the frameworks used in this paper.
A2. Control domains for governing agents
Start with the controls the organisation already uses. For each AI-enabled process, establish who owns the outcome, what agents may do without approval and which decisions remain with people.
The twelve control domains show where those controls may need extending, from planning and change management to oversight of live work. Use them to identify gaps in responsibility, control and evidence. The detailed reference is in Appendix 1.2.
Running example
The refund process has a business process owner, the head of customer operations, and a record of the three agents involved and the systems each can reach. Its specification defines the outcome: the right amount refunded, the customer's record corrected and an accurate reply.
The $250 limit on refunds an agent may issue alone is one expression of the firm's risk appetite. The process owner also weighs cumulative exposure, customer impact and how quickly errors can be found and corrected.

Part BOverseeing agents at work
During operation, business leaders need evidence that the work remains within the agreed requirements, and a defined response when it does not.
B1. People in the loop are essential
Agents change the work people must do. As routine cases are automated, reviewers may receive a higher proportion of ambiguous, disputed or consequential cases. Plan capacity for that workload, rather than assuming the old mix of cases still applies.
Industrial automation showed the same pattern: Bainbridge, Ironies of automation, Automatica 19(6), 1983, described how automation leaves operators the tasks designers could not automate, and how skills fade when they go unused.
Plan and budget for the people who review, correct and escalate the work as part of the business case. Give reviewers the authority to refuse, the evidence and expertise to judge, and enough time to act. Training, breaks and rotation should reflect the demands of the work.
Set limits on how much work can await review and for how long. Agree what happens when those limits are reached: add capacity, narrow what agents may do, slow the flow or escalate to the business process owner.
Track review delays, overrides, rework and recurring problems alongside speed and cost. To assess whether oversight works in practice, ask reviewers to show a recent case they refused, changed or escalated, and why.
Running example
Four approvers can handle about 300 cases a day, with an agreed queue limit of 600. A billing error increases cases needing approval to 500 a day. As the queue reaches its limit, customers receive a holding reply and the process owner brings in the extra approvers the plan provides for peaks, within the budget in the business case. The process owner then checks whether the added capacity cleared the queue and whether effort and cost stayed within plan.
Appendix 1.3 sets out roles, workload, skills and tools, review limits and measures in detail.
B2. Monitor outcomes and act when things go wrong
Agents may repeat an error across many transactions before anyone intervenes.
Before it runs. Define the intended outcome, operating limits and response to problems.
While it runs. Monitor business results as well as tasks completed. When conditions change significantly, reassess whether the work should continue.
When it goes wrong. Use the agreed response when outcomes deteriorate, controls fail or material conditions change. Systems enforce required holds; authorised people resolve exceptions and decide whether to continue, restrict or stop. Weigh potential harm, how quickly it could spread, whether it can be reversed, applicable obligations and the cost of interrupting service. Restricting one part may be better than stopping everything.
Running example
After a model update, the agent that replies to customers starts promising refunds outside the fee policy. Checks catch the problem. The business process owner restricts the agent's work: staff take over refund-eligibility questions, and the agent keeps handling other replies. Once the fix passes the agreed checks, the process owner returns those questions to the agent.
If the checking service is down, hold the work, or use a fallback that management has approved, provided the risk stays within the limits it has set. An outage is not a passed check.
Correct problems in completed work, decide whether subsequent work should continue and preserve a route for affected people to challenge the outcome.
See Responding when problems arise (Appendix 1.5) for required holds, fallback, correction and recovery.
B3. Controls in live operation
A written rule cannot prevent an action that an agent's tools still allow, so enforce limits through the systems it uses.
Record who owns each agent identity and give it only the access it needs. Test whether its access paths preserve the separation of duties the process requires.
Approve and record material changes to models, instructions, tools, data and permissions.
Where an action needs approval, the approval identifies that action and the recorded scope it permits. Reassess the approval when relevant conditions change.
Then check the business result. Authorisation does not establish that the work was accurate, complete or achieved its intended outcome. Controls in live operation (Appendix 1.4) shows how these controls apply to a refund requiring human approval.
B4. The role of assurance
Why it matters for agents
Assurance provides a supported assessment of whether agent work and its controls met agreed criteria within a defined scope and period. The assessment helps leaders decide how much authority agents should hold. It requires competent, objective reviewers, an agreed assessment process and systems that capture reliable evidence as the work happens.
Three features of agent-enabled work make this important:
- They change often. Models are updated, instructions and tools change and workflows are recomposed, sometimes by a supplier. Testing before an agent goes live shows how it behaved then, not how it behaves now.
- They can be wrong in convincing ways. Agents built on large language models produce likely answers rather than guaranteed ones. They can carry bias, which NIST's AI Risk Management Framework treats as a risk to manage, and in one study, five widely used AI assistants tended to favour a user's stated views over the correct answer.
- They cannot be relied on to check themselves. In one study, language models struggled to correct their own reasoning without outside feedback. Check the work against rules, source records or other evidence instead. A separate checking component helps, but does not by itself make the review independent.
Software delivery relies on testing and quality assurance before release. Agents need that discipline carried into live operation: checks on the work itself, as it runs and periodically, matched to the risk (Figure 7). Figure 8 gives examples.

| Check | What it does | Refund example |
|---|---|---|
| 1. Input check | Confirms the request and data are complete and valid before the agent acts | The request names a real transaction on the customer's account |
| 2. Rule and limit check | Tests the action against policy and authority limits | The refund is within $250 and the fee policy allows it |
| 3. Reconciliation | Compares the result with the system of record | The refund posted matches the approved amount and the right account |
| 4. Recalculation | Redoes the calculation separately | The amount is recomputed from the fee schedule |
| 5. Separate review | A separate rule set or model reviews the output | A second check reads each reply for promises the policy does not allow |
| 6. Sampled human review | A person reviews a sample, weighted to risk | A reviewer examines a weekly sample, weighted to new or unusual cases |
| 7. Outcome monitoring | Tracks results over time to spot drift | Reversals, repeat complaints and refund totals by week |
| 8. Re-check after change | Re-runs checks after a model, instruction, tool or supplier change | The reply checks re-run on recent cases after a model update |
Appendix 1 sets out the controls for each control domain.
Before relying on an assurance conclusion, ask what work and period it covers, what it was measured against, what was checked and what remains unresolved. Management's own checks support that assessment; independent assurance needs a reviewer who is independent of the work. Appendix 1.7 describes assurance more fully, including who provides it and how independence is judged.
What the evidence should show
Keep enough evidence to establish what work was done, what requirements applied, what was checked and what each result meant. Show the population in scope, the coverage achieved and any gaps. Preserve the history needed to understand earlier decisions under the organisation's retention requirements.
Keep failed, inconclusive and unassessed work separate: they require different follow-up. Give unresolved issues an owner and a next action.
The checks also need scrutiny. Review their test results, false alarms, missed errors, known limitations and failure modes before relying on their findings. Look beyond a single accuracy or confidence figure. Count errors by their consequences: unauthorised actions that went ahead, work refused that a person could have approved, and needless escalations.
Running example
Last week the process issued 4,800 refunds (Figure 9). A report showing only the 4,655 that passed would hide the rest. The process owner also needs to know the potential impact of unresolved cases and whether corrective actions are overdue.

Part COversight and standards
Each organisation designs its own controls for AI-enabled work, within the expectations that regulators and standards bodies set. Part C sets out which of them apply to agent work, then gives leaders the questions to ask management about whether the controls exist and work.
C1. Which requirements and guidance apply?
In the frameworks reviewed here, the recurring operating expectations are similar: clear accountability, defined authority and limits, controlled changes, human oversight where required, monitoring of live operation, evidence of what happened, and a response when things go wrong.
First determine, with risk, compliance and legal teams, which requirements apply to the AI-enabled process, given the organisation's role and jurisdiction, the system's intended use and classification, and application dates.
Requirements and guidance fall into four kinds:
- Binding legal and policy requirements, such as the EU AI Act and, for Canadian federal institutions, the Directive on Automated Decision-Making, apply by role, system and date.
- Supervisory guidance, such as OSFI's E-23, PRA SS1/23 and the US model-risk guidance, applies to regulated firms within its scope; SR 26-2 expressly leaves generative and agentic AI outside its scope. OSFI's July 2026 technology risk bulletin sets out sound practices institutions can consider.
- Voluntary frameworks, such as NIST AI RMF and ISO/IEC 42001, name functions and management-system requirements.
- Professional guidance, such as the IIA's, sets expectations for those who review the work.
The detailed table is in Appendix 2. It is a scoping aid, not a conformance assessment: each entry states what the regulation, standard or guidance contributes and what it leaves to you.
C2. Questions to ask management
Use these questions before agents are given more authority and at periodic reviews. Ask management to answer for a specific process, using recent work and supporting evidence.
| Executive question | Ask management to show |
|---|---|
| 1. Is the process delivering the intended outcome at an acceptable total cost? | Results and actual total cost against the business case, including technology and assurance costs, planned staffing, actual review and correction effort, and material variances. |
| 2. Who owns the result, and what may agents do without approval? | The business process owner, the agents and systems involved, enforced limits and decisions reserved for people. |
| 3. Are access and changes controlled? | Permissions in use and recent changes to models, instructions, tools or providers, with their impact assessed. |
| 4. Can people review exceptions competently and in time? | Capacity, training, queue age and examples of decisions reviewers refused, changed or escalated. |
| 5. When must we restrict or stop the work, and how do we recover? | Agreed triggers, decision authority, fallback and recovery arrangements, and routes for affected people to challenge outcomes. |
| 6. What is wrong, uncertain or unchecked, and what risk remains? | Coverage for a stated period, separate result categories, unresolved issues and their potential impact, owners and action dates, and any residual risk accepted by the business process owner within their authority. |
| 7. Who has challenged whether the controls and checks work? | The reviewer's scope, findings, limitations and independence from the work assessed. |
A practical next step
Choose one process where agents already do consequential work, and ask its business process owner to answer these questions.
Use the findings and the business case to decide whether the intended outcome is being achieved, review capacity matches demand, agent authority remains appropriate and wider use is justified. Decide what should continue, change or stop. Give each material gap an owner, an action and a date.
Checking agent work in live operation, and keeping the evidence that leaders and reviewers need, is the area iTmethods is focused on.
If you are running agents in live operation, we would welcome a conversation.

1.1 Oversight and the workflow
The main paper summarises management oversight in four steps.
The oversight loop is the organisation's management system: plan, do, check and act. It establishes policy and ownership, reviews risk and performance, and directs improvement.
The workflow loop follows one AI-enabled process from planning and design through build, verification and deployment, then operation, monitoring, assurance and response. Evidence from live operation informs decisions about continuing it and about changes to wider governance.
We infer the plan-do-check-act cycle from ISO/IEC 42001's clause structure. The workflow loop adapts the model lifecycle in OSFI's Guideline E-23 and extends it through operation, assurance and response. NIST's Govern, Map, Measure and Manage functions sit across both loops.
NIST AI RMF is a voluntary framework that sets out four functions for managing AI risk. ISO/IEC 42001 sets out requirements for an AI management system. OSFI Guideline E-23 takes effect 1 May 2027 and covers AI and ML models, including autonomous decision-making. Organisations still need to design the controls for an agent's tools and workflow.
1.2 Control domains
For each control domain, the table names the established control in generally accepted terms, the additional controls we propose for agent work, and the regulations and standards that map to it; Appendix 2 sets out their scope. Use it to check whether the controls you already run cover the work agents now do, and where they need extending.
Items 2 to 6 adapt the AI lifecycle stages in NIST AI RMF 1.0; the other domains group established control disciplines.
| # | Control domain | Established practice | What we propose for agent work | Standards and regulations |
|---|---|---|---|---|
| 1 | Governance and risk appetite | The board sets strategy and risk appetite, and management assigns accountability and keeps an inventory of the AI systems and models in use. | State what the business wants agents to achieve, the consequences it is prepared to accept and who remains accountable for the outcome. Extend the inventory into an agent registry: where each agent is deployed, in which workflows, its owner, and the tools, data and systems it can reach. Translate risk appetite into limits on what agents may do without a person approving each action, and cap the consequential work that may wait for review. | NIST AI RMF GOVERN 1.3 and 1.6; OSFI E-23 (model inventory); PRA SS1/23; HM Treasury Orange Book. OSFI's July 2026 bulletin recommends that institutions consider limits on autonomy. |
| 2 | Planning and design | Define requirements, acceptance criteria and a business process owner before anything is built. | Document a specification for each agent: intended outcomes, how they will be assessed, and the tools, data and systems it may use. Version the scope each agent is approved to act within, and keep requirements independent of the model under review. | EU AI Act Article 9; OSFI E-23; Canada's Algorithmic Impact Assessment. |
| 3 | Development | Build to the approved design with secure development practices and code review. | Treat prompts, tool definitions, components and settings as code: review, version and pin them. Retain evidence of how each agent was built and of the exact versions released. | EU AI Act Article 17; NIST SP 800-218 and 800-218A; EN 18286 (quality management system). |
| 4 | Verification and validation | Test against a plan before deployment, with validation independent of development where required. | Evaluate against a documented test plan that records expected results, actual results and the test environment. Include red-teaming and security testing of tools and access. Treat results as evidence about the conditions tested, and keep evaluating after deployment. | NIST AI RMF MEASURE; EU AI Act Article 15; PRA SS1/23. SR 26-2 leaves generative and agentic AI outside its scope. |
| 5 | Deployment and change management | Assess, test, approve and record changes before deployment; have rollout and rollback plans. | Track changes to models, prompts, data, tools and permissions separately. Plan rollout across technology, people and procedures, with reviewers ready. Start with limited use where the risk is higher, review results and confirm the approved scope before wider use. | OSFI's July 2026 bulletin recommends that institutions consider enterprise change controls for AI components. |
| 6 | Operations and monitoring | Monitor live operation against requirements, escalate issues and authorise someone to intervene. | People use current records of agent work and results to decide: continue, restrict or stop. Hold actions when required pre-action checks fail, are inconclusive or return nothing. Correct problems in completed work and decide whether work continues. Plan responses to problems. | EU AI Act Article 72, the OMB memoranda and Canada's Directive require post-deployment monitoring within their scope and application dates; E-23 and PRA SS1/23 expect it; NIST Manage recommends it; Article 14 adds human oversight. |
| 7 | Assurance | Management's own checks, oversight by risk and compliance, and independent assurance by internal audit (the three lines). | Check live work as it runs and periodically, with checks suited to the risk: for example, validating inputs and outputs against the defined requirements, testing policy and approval rules, reconciling results with the system of record, reperforming a sample of work, and human review where judgement is needed. Retain the evidence so internal audit, compliance and risk can review the checking, rely on it where warranted and evaluate the process itself. Report coverage as counts of what was and was not checked. Keep embedded checks distinct from independent assurance; reviewers need evidence access and stated limits. | IIA Global Internal Audit Standards (Domain I and Principle 7), GTAG 3 and AI Auditing Framework; PRA and US federal guidance support independent review; model-risk validation principles. |
| 8 | Incident and problem management | Log, investigate and resolve incidents, find root causes, and track corrective action to validated closure. | Distinguish a failed check, doubt, no result and an unavailable checking service. A stop is not a recovery: decide exceptions, reconcile work already started, authorise restart, and give people affected a route to challenge a decision. | EU AI Act Articles 14(4)(e) and 73; Canada's Directive on Automated Decision-Making; GAO Green Book. |
| 9 | Training and competence | Train people for their roles and assign accountability. | Train and support the people who direct and review agents, and build their expertise in evaluating agents' work. Give them the authority, evidence and time to act on what they find, and treat review capacity as a control limit with a budget. | EU AI Act Article 4 (AI literacy) and Article 14; NIST AI RMF GOVERN 2.2. |
| 10 | Security, identity and observability | Identity and access management, least privilege, segregation of duties, and security logging and monitoring. | Give each agent and tool an owned identity with constrained, short-lived credentials, and keep agents appropriately isolated. Test segregation through the access paths agents actually use, and assess impact by what an agent can reach. Log, monitor and trace agents' actions across the systems they touch. | OSFI B-13; FINOS; OWASP. OSFI's bulletin recommends that institutions consider non-human identities, least privilege and short-lived access. |
| 11 | Data governance | Govern data quality, lineage, relevance and retention. | Treat inputs, memory and generated outputs as controlled data: inputs can redirect an agent, and memory can be poisoned. Control their origin and lineage, and keep evidence with an owner and a retention rule. | OSFI E-23 Principle 3.2; EU AI Act Articles 10 and 12; OSFI July 2026 bulletin. |
| 12 | Third-party risk management | Due diligence, contracts, concentration risk, ongoing oversight and audit rights. | Cover model, tool and assurance providers. Reassess when a model or tool provider changes behaviour or components. Where a provider does not expose reasoning tokens, that part of its operation is unavailable for capture through the provider's interface. | OSFI's bulletin recommends that institutions consider third-party AI-use notification; NAIC lists contractual audit rights where appropriate and available. |
General IT controls continue to apply to the systems, data and infrastructure agents use; the table sets out the additional controls proposed for agent work.
1.3 Human review capacity
The work that reaches people changes. A team used to handle a mix of cases, many of them simple. Once agents take the routine cases, what reaches people is mostly what the agents escalate: the unusual, the ambiguous and the disputed, often with a customer already waiting. The remaining cases may take longer and require more judgment, and a full day of them is more tiring than a mixed workload. Plan staffing and support for that changed workload. The risk is that reviewers under that load, and under queue pressure, approve what is in front of them: the tendency the EU AI Act calls automation bias.
Plan the people in the loop like any other capacity:
- Roles. Who directs the agents, who reviews their work, who approves consequential actions and who corrects errors. Each needs the authority to say no, enough evidence, the knowledge to judge it and the time to do it.
- Load. Size teams for the harder cases that now reach them. Build in breaks, and rotation between demanding and lighter work, so that a reviewer at the end of a shift can still refuse.
- Skills and tools. Train people to handle escalated cases and to question an agent's output. Keep them doing some of the work themselves, so their judgement stays in practice. Give them tools that help: case summaries that show they were AI-generated, what they drew on and their limits; grouping of similar exceptions; and quick routes to specialists.
- Limits. How much work can wait for review, and for how long, before the agents' work is slowed, narrowed or escalated to the business process owner.
- Measures. A few that show whether oversight is working: the review queue against its limit, the age of the oldest case, how often people override the agent, and recurring problems.
What people in the loop do

EU AI Act Article 14 sets binding human-oversight requirements, subject to the Act's scope and application dates. Sizing the review capacity for each process is part of the organisation's own planning.
1.4 Controls in live operation
The five controls below change most when agents act in live operation. They build on controls most organisations already test, such as accountability, access and change control, and checks on each transaction, rather than adding a separate framework.
1. Limits on acting alone (Governance and risk appetite). Define what an agent may do without further approval, including the consequences of its actions, and enforce those limits through the system.
2. Access and segregation of duties (Security, identity and observability). Give each agent identity a named owner and only the access it needs. Make sure an agent cannot combine access or actions that would be kept apart for a person, and test this through the credentials and tools the agent actually uses.
3. Change control (Deployment and change management). Approve and record changes to models, prompts, tools, data and permissions. Where an action must be prevented, restrict the capability that enables it; a written instruction alone does not enforce that restriction.
4. Approval for one action (Deployment and change management). Our approval mechanism is designed to identify a specific action and a recorded version of its permitted scope. Reassess it when the relevant conditions change; a standing approval may no longer reflect the circumstances of the action.
5. Checks on completed work (Assurance). Check whether the completed work was accurate, complete, valid and within the approved scope. Authorisation is part of that assessment; it does not establish that the intended business outcome was achieved.
Running example
A customer asks for a $400 refund. The controls apply like this:
- The refund is over the agent's $250 limit, so the system holds it for a person.
- The agent can reach only the refunds system, nothing else.
- Changing the $250 limit takes an approved, recorded change to the refunds system itself.
- A person signs off this one refund. There is no blanket approval.
- A later check confirms the right customer received exactly $400, and the record and reply match.
OSFI's July 2026 bulletin sets out sound practices institutions can consider, complementing B-13, B-10 and E-21. FINOS and OWASP provide voluntary control catalogues. Management chooses which of these practices to adopt and how to apply them to its agents' actions.
1.5 Responding when problems arise
Problems surface through poor outcomes, failed checks, customer or staff reports, supplier changes or an unavailable checking service. When outcomes fall short or something material changes, the person authorised decides whether the work continues, is restricted or stops. The evidence informs that decision; a person makes it.
Weigh the impact. Base the response on the harm the problem could do to customers and the business. Weigh:
- how much damage one wrong action can do, and whether it can be reversed;
- how many customers or transactions it could reach, and how quickly;
- whether the problem is still happening or was a single event;
- what regulators, customers and contracts require, since some rules specify the response and its timing (see the box below);
- what it costs customers and the business to slow or stop the work.
Choose a response. Distinguish between a check that found a problem and a checking service that was unavailable.
- Continue and watch more closely. Check more cases, tighten alerts and follow the trend. Suits a contained, low-impact problem.
- Hold the action for a person. The system automatically holds the action if a required pre-action check fails, is inconclusive or returns no result. This includes a warning, a result marked not assessed or an abstention.
- Restrict. Lower limits, remove tools or send certain cases to people until the cause is fixed.
- Use an approved manual or fallback path. If the checking service is unavailable, pause the work. If the work cannot wait, use a manual or fallback path that management has approved, provided the risk stays within the limits it has set. Record the evidence gap and reconcile the work when checking resumes. An outage is not a passed check. A fallback is not permission for an agent to continue unchecked.
- Pause or stop the agents. Use this when harm could spread quickly or cannot be undone.
When a problem is found after an action, assign someone to correct or further check the completed work. An authorised person decides whether subsequent work should continue.
After a stop. The recovery plan assigns who reconciles unfinished work, corrects affected records and addresses the cause, accounting for unfinished actions and the people affected. The authorised person approves restart under the scope re-established in Figure 5 or a narrower one.
An authorised person decides how to resolve each exception; neither the agent nor the checker makes that disposition. The permitted decisions are reject; approve once, with conditions and an expiry; require remediation; narrow scope; escalate; suspend; or another disposition the organisation's mandate allows.
Confirm closure through a later check, preferably by someone other than the person who performed the remediation. Where a reviewer concludes that an exception was raised in error, retain the original finding and record it as “disputed as raised”, with the reason.
Record when the failure occurred separately from when it was discovered. Preserve the required route for review or recourse where a decision continues to affect a person.
Running example
One day, the system that checks each refund against the customer's account stops working. The process owner weighs the risk: each refund is small and can be reversed, and customers are waiting. Staff issue 130 refunds by hand, each within the usual limit and marked as not yet checked. When the system is back, the team checks those 130 against the customer accounts, and the process owner restarts normal work.
Reference case (chatbot)
In Moffatt v. Air Canada, 2024 BCCRT 149, the tribunal awarded damages for negligent misrepresentation after a customer reasonably relied on inaccurate chatbot advice. It rejected the airline's denial of responsibility, characterising that position as treating the chatbot as a separate legal entity. The case illustrates the record a reviewer needs: what the chatbot said, to whom, and when.
EU AI Act Article 14(4)(e) asks for a stop button or a similar procedure allowing a high-risk system to halt in a safe state. Under Article 26(5), a deployer that has reason to consider that a high-risk system presents a risk must inform the provider or distributor and the market surveillance authority without undue delay, and suspend its use; a serious incident must be reported immediately, first to the provider. Article 73 sets deadlines for reporting serious incidents: no later than 15 days after becoming aware, and shorter for the most serious cases. These apply subject to the Act's scope and application dates. Sector rules, such as financial-services incident reporting, may add their own duties. The restart, including reconciling unfinished work, remains a design decision for management.
1.6 Evidence records and coverage
Evidence is what lets someone check, later, whether something is or was true. Figure 13 shows what a reviewer asks about any check, and what to keep to answer each.
| Question | What to keep | Why it matters |
|---|---|---|
| 1. What did the check look at? | A record made when the check ran: the time, exact material examined and its source, the versions of the check and requirement, and the answer the check gave. | Material can change later. A model-based check may answer differently when re-run. |
| 2. How much was checked? | For a stated period, keep counts of the cases in scope, how many were checked and which were not. Take the total from the system of record. State when the total is unknown, whether every case or a sample was checked, and how any sample was chosen. | The total includes work the check missed. Figure 9 illustrates the counts for one week. |
| 3. What did each result mean? | Record failed, inconclusive and not assessed separately: a breach is a failure; missing evidence is inconclusive; not assessed means no check was performed. | Each result needs different follow-up. See Responding when problems arise (Appendix 1.5). |
| 4. What did an earlier decision rely on? | Keep the original record. Add corrections beside it with the date, reason and who made them. Check that restoring or restarting a system leaves earlier records intact. | Shows what earlier decisions relied on and what changed. |
| 5. Can a reviewer check it for themselves? | An evidence package with enough for a competent reviewer to follow each check to the same conclusion, and an integrity check they can run independently of the team that produced it. | Lets the reviewer reach their own conclusion and confirm the records are unchanged. Integrity checks do not establish that the underlying work was correct or the evidence complete. |
The five answers help a reviewer judge whether evidence is relevant, reliable and sufficient, the tests the IIA's Global Internal Audit Standards set for the information internal auditors gather (Standard 14.1).
Assign responsibility for applying the organisation's retention and deletion requirements to these records, including the tool settings. Keep the material a record identifies for as long as the record itself, within data protection limits, so a reviewer can still follow the check.
EU AI Act Article 12 sets a binding technical logging requirement for high-risk systems, subject to the Act's application dates. Article 26(6), on the same dates, requires deployers to keep the logs those systems generate automatically, to the extent the logs are under their control, for a period appropriate to the intended purpose of the high-risk AI system, of at least six months, unless provided otherwise in applicable Union or national law, in particular Union law on the protection of personal data. An evidence package supports your obligations under logging and record-keeping duties, and is neither an attestation nor a certification. Beyond these logs, the organisation determines what evidence its checks keep and who owns it.
1.7 Review arrangements and independence
What assurance involves
Assurance means two things. It is a conclusion: a statement of how far leaders can rely on what was done, judged against suitable criteria. It is also the work that produces that conclusion: examining and testing what actually happened against those criteria.
Delivering assurance takes four things together:
- People. Competent, objective reviewers: management checks the work, risk and compliance oversee it, and internal audit or an external provider reviews it independently.
- Process. Criteria suited to the risks and objectives, a defined scope and period, and an agreed method for testing the work and recording the conclusion.
- Technology. Systems that capture evidence as the work happens, keep it intact and let a reviewer reach it.
- Evidence. Relevant, reliable and sufficient records, each showing where it came from and what it covers.
Management's own checks support an assurance assessment. Independent assurance needs a reviewer who is independent of the work and reaches their own conclusion from the evidence. Management, risk and compliance, and the independent reviewer each test the evidence before relying on it.
Embedded controls and independent assurance are distinct disciplines. An embedded checker can be useful and still not be independent. An operational checking service used by management remains part of management's controls, even when an external supplier operates it. An external assurance engagement is a separate arrangement, assessed against its mandate and independence requirements. Internal audit can provide independent assurance where it is positioned independently, with the chief audit executive reporting directly to the board, as can an external assurance provider within its mandate and independence requirements.
The reviewer weighs all the evidence for relevance, reliability and sufficiency: the operator's own records, model-provider tests and platform controls, each with its origin and scope visible. The reviewer also needs evidence about the checker itself: test results, false alarms, known failure modes and the classes of problem it has not seen. In our own testing, all findings in one overnight run traced to one checker bug.
Internal audit can rely on management's checks and on other assurance providers once it has evaluated them: who did the work, how independent and competent they are, how they did it, and whether the evidence supports their results. It records the basis for that reliance. The reviewer must assess the evidence and reach their own conclusion about what it supports. Each finding then needs an owner and a date for correction.
Running example
As part of its risk-based audit plan, internal audit reviews the refund process and its controls. For a sample of refunds, it checks that each was properly authorised, correctly calculated, backed by evidence and paid to the right customer. It then reports, for a stated period, whether the controls were designed well and worked as intended. The weekly report is one input; the conclusion is internal audit's own.
PRA SS1/23 and OSFI E-23 expect validation independent of model development within their scope. US federal guidance also requires uninvolved review in specified cases. SR 26-2 expressly leaves generative and agentic AI outside its scope. PRA SS1/23 has no equivalent exclusion: at firms within its scope, its model definition and validation principles must be considered when assessing an agent's underlying models. The organisation decides where independent review of agent work is required and who can perform it.

Appendix 3. Glossary
- Agent
- Software that can choose steps or tools and take business actions.
- AI-enabled work
- Business work in which an AI system decides, recommends or acts.
- Assurance
- Both a conclusion and the work that produces it: a statement, measured against agreed criteria, of how far leaders can rely on a piece of work, and the examining and testing behind it (after the IIA Global Internal Audit Standards). Independent assurance needs reviewers independent of the work and of the checks built into it.
- Continuous assurance, as used in this paper
- Checking AI-enabled work against its intended business outcome and agreed requirements, using the evidence to inform decisions on whether the work continues and within what limits.
- Coverage
- The work assessed over a stated period, with the in-scope population and selection method made clear. State when the total population is unknown.
- Failed / inconclusive / not assessed
- Failed: examined, and the evidence shows the requirement was not met. Inconclusive: examined but unresolved, for example because evidence was missing. Not assessed: not examined.
- Exception and disposition
- An issue raised by a check, and the decision an authorised person makes about it.
- Evidence package
- A bundle of evidence and verification material prepared for review.
- Reperformance
- Running a check again. It is distinct from an independent re-execution by an outside party.
- Non-human identity
- The credential or workload identity an agent uses, with a named owner.
