Corrective Action Report

Also known as: CAR, Corrective Action Request, Corrective Action Plan
Simply put

A Corrective Action Report is a formal document that an organization uses to record a problem, deviation, or nonconformity and describe the steps taken to fix it. It helps organizations address issues in their processes, services, or products in a structured, documented way. The term is sometimes used interchangeably with 'Corrective Action Request,' though the two can refer to slightly different stages of the same overall process.

Formal definition

A Corrective Action Report (CAR) is a formal reporting instrument used to capture information about nonconformities, discrepancies, or deviations from established quality standards or regulatory requirements, and to document the actions taken to address and resolve them. It is commonly associated with quality management practices such as those under ISO 9001 and with process-improvement methodologies including Lean Six Sigma, where it is used to record repeated nonconformities or problems and the corrective measures applied. Practitioners should note that 'Corrective Action Report' and 'Corrective Action Request' are sometimes distinguished (the request initiating action, the report documenting outcomes) and sometimes treated as synonyms; the precise scope and required contents vary by organization and applicable standard. The evidence provided describes CARs in a general quality-management and process-improvement context and does not establish a definition specific to AI governance or model risk management.

Why it matters

A Corrective Action Report matters because it converts an identified problem into a documented, traceable record of what went wrong and what was done about it. In quality management contexts such as those associated with ISO 9001, this documentation supports accountability: it demonstrates that a nonconformity was not merely noticed but formally addressed, and it creates an audit trail that internal reviewers and external assessors can examine. Without such a record, organizations risk treating recurring issues as one-off events rather than as signals requiring systematic correction.

In AI governance and model risk management, structured documentation of deviations and their remediation aligns with the broader control expectations these disciplines emphasize, though it is important to be precise about scope. The evidence available here describes CARs in a general quality-management and process-improvement setting and does not establish a CAR definition specific to AI systems, model validation findings, or model risk frameworks such as SR 11-7. Practitioners should therefore treat any application of the CAR concept to AI oversight as an adaptation of a general quality tool rather than a term with a settled AI-specific meaning.

A further reason the term warrants care is that a Corrective Action Report reduces and manages risk; it does not eliminate it. Documenting a corrective action does not by itself confirm that the underlying cause has been resolved or that recurrence is prevented, and the precise required contents vary by organization and applicable standard. Confusing the existence of a report with the effectiveness of the remediation is a common pitfall.

Who it's relevant to

Compliance and quality management professionals
Those responsible for conformance to standards such as ISO 9001 use CARs to record nonconformities and demonstrate that identified problems have been formally addressed. For this audience the report serves as evidence within audit trails, though its required contents vary by organization and applicable standard.
Auditors and assessors
Internal and external reviewers rely on Corrective Action Reports to trace how a deviation was handled. They should distinguish the existence of a documented action from confirmation that the underlying cause was resolved, and should verify effectiveness rather than treat the report alone as proof of remediation.
Process-improvement and operations practitioners
Teams applying methodologies such as Lean Six Sigma use CARs to document repeated nonconformities and the corrective measures applied, supporting structured, documented problem resolution across processes, services, or products.
AI governance and model risk practitioners (with caution)
Professionals in AI governance or model risk management may adapt the general CAR concept to document and track remediation of identified issues. However, the evidence here defines CARs only in a general quality-management context and does not establish an AI-specific or model-risk-specific definition; any such application should be treated as an adaptation and scoped explicitly within the organization's own framework.

Inside CAR

Issue or Finding Description
A clear statement of the deficiency, weakness, or non-conformance being addressed, typically identified through validation, audit, monitoring, or a second- or third-line-of-defense review. The description usually captures what was observed and where it was identified.
Root Cause Analysis
An assessment of the underlying cause of the issue rather than only its symptoms. In many governance and model risk management contexts, distinguishing the root cause from the observed effect is what allows a corrective action to prevent recurrence rather than temporarily mask a problem.
Risk Rating or Severity
An indication of the significance of the issue, often expressed in terms of impact and likelihood. Practices vary across organizations and frameworks, so the rating scheme is typically defined by internal policy rather than a single universal standard.
Remediation Plan
The specific actions intended to address the issue, commonly framed as measures that reduce or manage risk rather than eliminate it. This may distinguish immediate containment steps from longer-term corrective measures.
Ownership and Accountability
Assignment of responsibility for executing and overseeing the corrective action, often mapped to a line of defense or a specific role. This connects the report to broader accountability structures within AI governance.
Target Dates and Milestones
Planned timelines for completion, including interim checkpoints where applicable. These support tracking and follow-up rather than serving as a guarantee of resolution.
Status and Verification of Closure
A record of progress and the basis on which the action is considered complete. Verification that a remediation was implemented is conceptually distinct from validation that the remediation is effective; some reports capture both, and practices differ across organizations.

Common questions

Answers to the questions practitioners most commonly ask about CAR.

Is a Corrective Action Report the same as a model validation report?
No. A model validation report documents an independent assessment of whether a model is sound, appropriately implemented, and used as intended. A Corrective Action Report, by contrast, typically documents the response to an identified deficiency, issue, or finding—describing what will be done, by whom, and by when to remediate it. Validation may generate findings that trigger corrective actions, but the two documents serve different functions and should not be conflated. Treating a corrective action report as evidence that validation itself has occurred is a common error.
Does completing a Corrective Action Report mean the underlying risk has been eliminated?
Not necessarily. A Corrective Action Report generally documents measures intended to reduce or manage an identified issue, not proof that risk has been removed. Even after remediation, some residual risk typically remains, and the effectiveness of the corrective action usually needs to be verified before an issue is considered resolved. Professionals frequently err by treating closure of the report as equivalent to closure of the risk itself, rather than as one step in an ongoing monitoring and control process.
Who is typically responsible for preparing and owning a Corrective Action Report?
Ownership commonly sits with the party accountable for the deficient process or model—often within the first line of defense—while independent functions such as model risk management or internal audit may raise the finding and later assess remediation. Responsibilities vary by organization and framework, so roles should be defined in internal policy rather than assumed. In many governance structures, clear assignment of an accountable owner, distinct from the reviewer who verifies the fix, helps preserve independence.
What elements are commonly included in a Corrective Action Report?
As commonly structured, such reports include a description of the identified issue or finding, an assessment of its severity or risk rating, the root cause where determinable, the specific remediation actions planned, an accountable owner, a target completion date, and criteria for verifying effectiveness. The precise required fields depend on internal policy and any applicable framework, so organizations should align the template to their own governance and documentation standards.
How should the effectiveness of a corrective action be verified before closure?
Verification typically involves confirming, through evidence rather than assertion, that the planned actions were implemented and that they address the original deficiency. This is often performed by a party independent of the one that carried out the remediation. Distinguishing implementation (the action was completed) from effectiveness (the action resolved the issue) is important; a report may show completed steps yet still require follow-up if the underlying problem persists.
How do Corrective Action Reports fit into broader governance and issue-tracking processes?
They commonly serve as a documented link between the identification of an issue and its resolution, feeding into issue-management or remediation-tracking systems used by governance and oversight functions. Overdue or recurring actions can signal control weaknesses that warrant escalation. The specific integration with governance committees, risk registers, or audit workflows varies by organization, so the report's role should be defined within the entity's own oversight framework rather than assumed to follow a single standard.

Common misconceptions

A corrective action report is essentially the same as an audit finding or a validation report.
As commonly understood, these serve different functions. A finding or validation report identifies and characterizes an issue, whereas a corrective action report focuses on the response—root cause, remediation plan, ownership, and closure. They are typically related and cross-referenced but are not interchangeable documents.
Closing a corrective action report means the underlying risk has been eliminated.
Corrective actions are generally described as measures that reduce or manage risk, not eliminate it. Closure typically reflects that planned actions were implemented and, in some cases, verified as effective; residual risk may remain and is usually managed separately.
Corrective action reporting is a single standardized process defined by one authoritative framework.
The specific structure, risk-rating scheme, and closure criteria are typically set by internal policy and vary across organizations and sectors. There is no single universal definition that applies identically across banking model risk contexts and general enterprise AI governance contexts.

Best practices

Document the root cause distinctly from the observed symptom, so that the remediation addresses the underlying driver rather than only its surface effect.
Assign clear ownership and, where relevant, map accountability to the appropriate line of defense to avoid ambiguity about who executes versus who oversees the action.
Distinguish verification that a remediation was implemented from validation that it is effective, and record the basis for closure accordingly.
Use a defined, policy-based risk rating so severity is applied consistently and follow-up is prioritized appropriately.
Set realistic target dates with interim milestones and track progress, treating timelines as management tools rather than guarantees of resolution.
Frame remediation outcomes in terms of reducing or managing risk, and explicitly note any residual risk that persists after the action is complete.
