NIST AI RMF, Dissected

Every control in the NIST AI Risk Management Framework, broken down: what it requires, why it matters, how to meet it, and the evidence your auditor will ask for.

How the Framework Fits Together

NIST AI 100-1 (AI RMF 1.0) is a voluntary framework, but it has become the reference point U.S. customers, auditors and regulators use to judge whether an AI program is credible. Its Core is organized into four functions. GOVERN runs through all of them, and MAP, MEASURE and MANAGE repeat across each AI system's lifecycle.

◆ "Controls" vs. subcategories

NIST calls them subcategories, and they describe outcomes, not prescriptive controls. You choose how to achieve each one. That flexibility is useful, but it also means an assessor will ask for evidence that the outcome is actually met.

◆ Using generative AI?

Pair this guide with NIST AI 600-1, the Generative AI Profile. It maps 12 GenAI-specific risks, including confabulation, information security, data privacy and harmful content, onto these same subcategories with suggested actions.

◆ Scale to risk

Not every system needs every outcome at full depth. Tier your AI systems (GOVERN 1.3) and apply the heaviest treatment to high-impact ones. A marketing copy tool and a clinical triage model should not get the same review.

Govern

Cultivate a culture of AI risk management

GOVERN is cross-cutting: it sets the policies, accountability, culture and supply-chain rules that make the other three functions possible. Without it, MAP, MEASURE and MANAGE become one-off exercises nobody owns.

GV-1

Policies, processes, procedures, and practices across the organization related to the mapping, measuring, and managing of AI risks are in place, transparent, and implemented effectively.

GOVERN 1.1 Legal & regulatory requirements are understood
NIST outcomeLegal and regulatory requirements involving AI are understood, managed, and documented.

Why it matters

AI is now regulated from several directions at once: the EU AI Act, U.S. state laws (Colorado, NYC Local Law 144, California), sector rules such as HIPAA and FDA guidance for software as a medical device, and privacy laws that already cover automated decision-making. You cannot manage a risk you have not identified, and "we didn't know" is not a defense regulators accept.

How to meet it

  • Build an AI regulatory register: each law or standard, which systems it touches, the obligation, the owner and the deadline.
  • Classify each AI system against the EU AI Act risk tiers and any sector-specific rules that apply to it.
  • Have legal and privacy counsel review the register at least quarterly and whenever you enter a new market or launch a new use case.
  • Link each obligation to a control or policy so you can show coverage, not just awareness.
Evidence an auditor will ask for
  • AI regulatory register
  • Legal review sign-off
  • Obligation-to-control mapping
Link to GOVERN 1.1
GOVERN 1.2 Trustworthy-AI characteristics are built into policy
NIST outcomeThe characteristics of trustworthy AI are integrated into organizational policies, processes, procedures, and practices.

Why it matters

NIST defines trustworthy AI as valid and reliable, safe, secure and resilient, accountable and transparent, explainable and interpretable, privacy-enhanced, and fair with harmful bias managed. If these only appear in a values statement, engineering teams will optimize for speed and accuracy alone. Writing them into policy makes them requirements.

How to meet it

  • Publish an AI policy (or extend your existing security policy) that names each trustworthiness characteristic and what it means for your products.
  • Translate each characteristic into concrete gates in the SDLC, for example a bias evaluation before launch or explainability documentation for high-impact decisions.
  • Add trustworthiness criteria to design-review and change-approval templates.
  • Train product and engineering leads on what the policy requires of them.
Evidence an auditor will ask for
  • Approved AI policy
  • SDLC gate checklist
  • Design-review templates
Link to GOVERN 1.2
GOVERN 1.3 Risk management effort scales with risk tolerance
NIST outcomeProcesses, procedures, and practices are in place to determine the needed level of risk management activities based on the organization's risk tolerance.

Why it matters

A marketing copy assistant and a model that triages patients do not deserve the same scrutiny. Without a tiering method, teams either drown low-risk tools in paperwork or let high-risk systems through with too little review. Both outcomes undermine the program.

How to meet it

  • Define AI risk tiers (for example Low / Moderate / High / Prohibited) with objective criteria: decision impact, autonomy, data sensitivity, affected population and regulatory exposure.
  • Map each tier to required activities, such as a lightweight intake for Low and a full impact assessment, red teaming and executive sign-off for High.
  • Have leadership approve a written risk-appetite statement for AI.
  • Require tier assignment at intake and re-tiering on material change.
Evidence an auditor will ask for
  • AI risk-tiering methodology
  • Board/executive-approved risk appetite
  • Tier-to-activity matrix
Link to GOVERN 1.3
GOVERN 1.4 Risk process is transparent and controlled
NIST outcomeThe risk management process and its outcomes are established through transparent policies, procedures, and other controls based on organizational risk priorities.

Why it matters

If risk decisions happen in hallway conversations, nobody can audit them, repeat them or learn from them. A documented process means that when a customer, auditor or regulator asks why a system was approved, the answer is a record and not someone's recollection.

How to meet it

  • Document the end-to-end AI risk workflow: intake, assessment, decision, treatment, acceptance and review.
  • Use a single system of record (GRC tool, ticketing system or risk register) for all AI risk decisions.
  • Define who can accept which level of residual risk.
  • Make the process visible internally so teams know how to engage it.
Evidence an auditor will ask for
  • AI risk management procedure
  • Risk register with decisions
  • Delegation-of-authority matrix
Link to GOVERN 1.4
GOVERN 1.5 Ongoing monitoring and periodic review are planned
NIST outcomeOngoing monitoring and periodic review of the risk management process and its outcomes are planned and organizational roles and responsibilities clearly defined, including determining the frequency of periodic review.

Why it matters

Models drift, regulations change, vendors swap model versions without notice and new attack techniques appear every month. A risk assessment from last year describes a system that may no longer exist. Scheduled review is how the program stays accurate.

How to meet it

  • Set review frequencies by tier, for example High-risk systems quarterly, Moderate yearly and Low on change only.
  • Assign a named owner to each review and track completion.
  • Review the program itself every year: is tiering working, are assessments useful, what incidents did it miss?
  • Define triggers for out-of-cycle review: a model change, a new data source, an incident or a regulatory change.
Evidence an auditor will ask for
  • Review calendar
  • Completed review records
  • Annual program review report
Link to GOVERN 1.5
GOVERN 1.6 AI systems are inventoried
NIST outcomeMechanisms are in place to inventory AI systems and are resourced according to organizational risk priorities.

Why it matters

The inventory is the foundation of the whole program. Most organizations underestimate their AI footprint by a wide margin once they count SaaS features with embedded AI, browser extensions, copilots and shadow use of public chatbots. Every other control depends on knowing what exists.

How to meet it

  • Create an AI inventory capturing owner, purpose, model/vendor, data used, users, risk tier, deployment status and last review date.
  • Feed it from several sources: procurement intake, SaaS discovery and CASB logs, cloud API usage (OpenAI, Anthropic, Bedrock, Vertex) and engineering surveys.
  • Make registration a prerequisite for production deployment and for vendor purchase approval.
  • Reconcile the inventory against discovery data every quarter to catch shadow AI.
Evidence an auditor will ask for
  • AI system inventory
  • Discovery/reconciliation reports
  • Intake procedure
Link to GOVERN 1.6
GOVERN 1.7 Safe decommissioning is defined
NIST outcomeProcesses and procedures are in place for decommissioning and phasing out AI systems safely and in a manner that does not increase risks or decrease the organization's trustworthiness.

Why it matters

Retired models leave behind training data, embeddings, fine-tuned weights, API keys and downstream integrations that still expect output. Switching one off carelessly can break dependent processes, orphan sensitive data or leave an exposed endpoint running for years.

How to meet it

  • Write a decommissioning checklist covering dependency mapping, user notification, fallback process, data and model artifact retention or deletion, credential revocation and endpoint shutdown.
  • Apply data-retention rules to training sets, vector stores, prompts and logs.
  • Record the retirement decision and its rationale in the inventory.
  • Verify after shutdown that endpoints and keys are actually gone.
Evidence an auditor will ask for
  • Decommissioning procedure
  • Completed decommission checklists
  • Inventory status history
Link to GOVERN 1.7
GV-2

Accountability structures are in place so that the appropriate teams and individuals are empowered, responsible, and trained for mapping, measuring, and managing AI risks.

GOVERN 2.1 Roles and lines of communication are documented
NIST outcomeRoles and responsibilities and lines of communication related to mapping, measuring, and managing AI risks are documented and are clear to individuals and teams throughout the organization.

Why it matters

AI risk falls between security, privacy, legal, data science and product, and each group tends to assume another one owns it. Clear roles stop gaps and duplicated work, and they tell people who to escalate to when a model misbehaves.

How to meet it

  • Build a RACI for the AI lifecycle: intake, assessment, approval, monitoring, incidents and retirement.
  • Name a system owner for every inventoried AI system.
  • Set up an AI governance committee or working group with a charter, members and meeting cadence.
  • Publish the escalation path for AI concerns where employees will actually find it.
Evidence an auditor will ask for
  • AI RACI matrix
  • Governance committee charter
  • Meeting minutes
Link to GOVERN 2.1
GOVERN 2.2 Personnel and partners are trained
NIST outcomeThe organization's personnel and partners receive AI risk management training to enable them to perform their duties and responsibilities consistent with related policies, procedures, and agreements.

Why it matters

Most AI incidents begin with a well-meaning person: a developer pasting secrets into a chatbot, an analyst trusting a hallucinated citation, a manager relying on a biased screening tool. Policies only work when the people who must follow them understand them.

How to meet it

  • Give all staff baseline training on acceptable AI use, data handling and spotting unreliable output.
  • Add role-based training: secure LLM development and prompt injection for engineers, bias and evaluation for data scientists, AI contracting for procurement, oversight duties for executives.
  • Include AI obligations in partner and contractor onboarding.
  • Track completion and refresh content every year as the threat landscape changes.
Evidence an auditor will ask for
  • Training curricula
  • Completion records
  • Acceptable-use acknowledgments
Link to GOVERN 2.2
GOVERN 2.3 Executive leadership owns AI risk decisions
NIST outcomeExecutive leadership of the organization takes responsibility for decisions about risks associated with AI system development and deployment.

Why it matters

AI risk is business risk, covering liability, reputation and regulatory exposure. If decisions sit only with engineers, high-impact tradeoffs get made without the authority or context they need. Regulators and boards increasingly expect a named executive to be accountable.

How to meet it

  • Name an accountable executive for AI risk (often the CISO, CRO, CTO or a Chief AI Officer).
  • Require executive sign-off to accept residual risk on High-tier systems.
  • Report AI risk posture to the board or its risk committee at least quarterly.
  • Document executive decisions together with the risk information presented to them.
Evidence an auditor will ask for
  • Executive accountability designation
  • Risk-acceptance sign-offs
  • Board reporting decks/minutes
Link to GOVERN 2.3
GV-3

Workforce diversity, equity, inclusion, and accessibility processes are prioritized in the mapping, measuring, and managing of AI risks throughout the lifecycle.

GOVERN 3.1 Decisions are informed by a diverse team
NIST outcomeDecision-making related to mapping, measuring, and managing AI risks throughout the lifecycle is informed by a diverse team (e.g., diversity of demographics, disciplines, experience, expertise, and backgrounds).

Why it matters

Blind spots are the main source of AI harm. A team made up only of ML engineers will miss clinical, legal, accessibility or cultural failure modes that a nurse, lawyer, accessibility specialist or member of the affected community would see right away. Range of perspective is a risk-detection control.

How to meet it

  • Staff AI risk reviews with several disciplines: security, privacy, legal, domain experts, UX/accessibility and, where relevant, representatives of affected users.
  • Set minimum reviewer composition for High-tier assessments.
  • Record who took part in each assessment and what each discipline contributed.
  • Bring in outside reviewers where you lack the expertise internally.
Evidence an auditor will ask for
  • Assessment participant lists
  • Reviewer composition standard
  • Review comments by discipline
Link to GOVERN 3.1
GOVERN 3.2 Human-AI roles and oversight are defined
NIST outcomePolicies and procedures are in place to define and differentiate roles and responsibilities for human-AI configurations and oversight of AI systems.

Why it matters

"Human in the loop" means nothing unless you define who the human is, what they review, what authority they have and how much time they get. Without that, oversight turns into rubber-stamping. This is also a direct requirement for high-risk systems under the EU AI Act (Article 14).

How to meet it

  • For each system, define the oversight model: human-in-the-loop (approves every decision), human-on-the-loop (monitors and can intervene) or human-out-of-the-loop.
  • Set reviewer qualifications, override authority and workload limits.
  • Design the interface so reviewers see confidence, rationale and the input data, not just a recommendation.
  • Monitor override rates. An override rate near zero can mean automation bias rather than a perfect model.
Evidence an auditor will ask for
  • Human oversight design per system
  • Reviewer role descriptions
  • Override-rate metrics
Link to GOVERN 3.2
GV-4

Organizational teams are committed to a culture that considers and communicates AI risk.

GOVERN 4.1 Critical thinking and safety-first mindset
NIST outcomeOrganizational policies and practices are in place to foster a critical thinking and safety-first mindset in the design, development, deployment, and uses of AI systems to minimize potential negative impacts.

Why it matters

Pressure to ship AI features is intense. If raising a concern feels career-limiting, problems surface only after they hurt someone. A culture where challenging an AI design is expected catches issues while they are still cheap to fix.

How to meet it

  • Add structured "what could go wrong" exercises (pre-mortems, abuse-case and threat modeling) to AI design reviews.
  • Give reviewers explicit authority to block or pause launches, and protect people who raise concerns.
  • Recognize teams that find and fix risks, not only teams that ship.
  • Have leaders talk openly about risks they chose not to take.
Evidence an auditor will ask for
  • Pre-mortem/threat-model records
  • Launch-gate decisions including stops
  • Speak-up / non-retaliation policy
Link to GOVERN 4.1
GOVERN 4.2 Teams document and communicate impacts
NIST outcomeOrganizational teams document the risks and potential impacts of the AI technology they design, develop, deploy, evaluate, and use, and they communicate about the impacts more broadly.

Why it matters

Knowledge that stays in one team's heads leaves when they do. Documented impacts let downstream teams, customers and auditors understand what a system can and cannot do, and they are the raw material for model cards, transparency notices and regulatory filings.

How to meet it

  • Require a model card or system card for every Moderate or High-tier system covering purpose, data, performance, limitations and known risks.
  • Run an AI impact assessment for High-tier systems and share a summary with affected stakeholders.
  • Publish user-facing transparency notes where appropriate.
  • Store documentation centrally and version it with the system.
Evidence an auditor will ask for
  • Model/system cards
  • AI impact assessments
  • Transparency notices
Link to GOVERN 4.2
GOVERN 4.3 Testing, incident identification and sharing are enabled
NIST outcomeOrganizational practices are in place to enable AI testing, identification of incidents, and information sharing.

Why it matters

AI fails in new ways: jailbreaks, prompt injection, data poisoning, harmful outputs and silent accuracy decay. Teams need permission, tools and channels to test for these and to report what they find, both inside the company and with the wider community.

How to meet it

  • Fund and authorize AI red teaming and adversarial testing, including for third-party models you deploy.
  • Extend the incident response plan with AI incident categories and severity criteria.
  • Give employees and users a simple way to report AI misbehavior.
  • Take part in information sharing, for example your sector ISAC or public incident databases, and track threat intelligence such as MITRE ATLAS and the OWASP Top 10 for LLM Applications.
Evidence an auditor will ask for
  • Red-team reports
  • AI-specific IR playbook
  • Incident/issue reports
  • Threat-intel sources
Link to GOVERN 4.3
GV-5

Processes are in place for robust engagement with relevant AI actors.

GOVERN 5.1 External feedback on impacts is collected
NIST outcomeOrganizational policies and practices are in place to collect, consider, prioritize, and integrate feedback from those external to the team that developed or deployed the AI system regarding the potential individual and societal impacts related to AI risks.

Why it matters

The people affected by an AI system, such as patients, applicants, customers or citizens, often notice harms the builders never anticipated. Without a channel for their feedback, you learn about problems from journalists, lawsuits or regulators.

How to meet it

  • Provide in-product feedback and contest mechanisms for AI-driven outcomes.
  • Run user research, advisory panels or community consultations for High-tier systems.
  • Triage external feedback with defined service levels and route it to system owners.
  • Report feedback themes to the governance committee.
Evidence an auditor will ask for
  • Feedback channels
  • Feedback triage log
  • Consultation records
Link to GOVERN 5.1
GOVERN 5.2 Adjudicated feedback is incorporated
NIST outcomeMechanisms are established to enable the team that developed or deployed AI systems to regularly incorporate adjudicated feedback from relevant AI actors into system design and implementation.

Why it matters

Collecting feedback that never changes anything is worse than not collecting it, because it erodes trust. This outcome closes the loop: valid feedback becomes backlog items, retraining data or design changes.

How to meet it

  • Define how feedback is adjudicated: who decides it is valid and how it is prioritized.
  • Create backlog tickets linked to each feedback item.
  • Track time from accepted feedback to shipped change.
  • Tell submitters what changed where you can.
Evidence an auditor will ask for
  • Adjudication criteria
  • Linked backlog items
  • Feedback-to-fix metrics
Link to GOVERN 5.2
GV-6

Policies and procedures are in place to address AI risks and benefits arising from third-party software and data and other supply chain issues.

GOVERN 6.1 Third-party AI risks, including IP, are addressed
NIST outcomePolicies and procedures are in place that address AI risks associated with third-party entities, including risks of infringement of a third-party's intellectual property or other rights.

Why it matters

Most organizations consume AI rather than build it: foundation model APIs, SaaS features, open-weight models and licensed datasets. Each one brings risks you inherit, including data use for training, unclear licensing, copyright exposure, model changes and vendor security posture.

How to meet it

  • Add AI-specific questions to vendor due diligence: training on customer data, data residency, model provenance, evaluation results, sub-processors and incident notification.
  • Negotiate contract terms covering no training on your data, IP indemnification, model change notice, audit rights and breach notification.
  • Check licenses for open-weight models and datasets before use.
  • Keep an AI bill of materials (AI-BOM) for each system.
Evidence an auditor will ask for
  • AI vendor questionnaire
  • Contract clause library
  • License reviews
  • AI-BOMs
Link to GOVERN 6.1
GOVERN 6.2 Contingency for high-risk third-party failures
NIST outcomeContingency processes are in place to handle failures or incidents in third-party data or AI systems deemed to be high-risk.

Why it matters

Model providers have outages, deprecate versions, change safety filters and suffer breaches. If a critical workflow depends on one external model with no fallback, the vendor's bad day becomes yours.

How to meet it

  • Identify which third-party AI dependencies support High-tier or business-critical processes.
  • Define fallbacks: an alternate provider, a pinned model version, a degraded non-AI mode or a manual process.
  • Test failover at least once a year.
  • Include vendor AI incidents in your incident response and communication plans.
Evidence an auditor will ask for
  • Third-party AI dependency map
  • Contingency/BCP plans
  • Failover test results
Link to GOVERN 6.2

Map

Context is recognized and risks related to context are identified

MAP establishes the context for each AI system: what it is for, who it affects, what it depends on and what could go wrong. Its output feeds MEASURE and MANAGE. Skip it, and you end up measuring the wrong things very precisely.

MP-1

Context is established and understood.

MAP 1.1 Intended purpose and deployment context are documented
NIST outcomeIntended purposes, potentially beneficial uses, context-specific laws, norms and expectations, and prospective settings in which the AI system will be deployed are understood and documented. Considerations include: the specific set or types of users along with their expectations; potential positive and negative impacts of system uses to individuals, communities, organizations, society, and the planet; assumptions and related limitations about AI system purposes, uses, and risks across the development or product AI lifecycle; and related TEVV and system metrics.

Why it matters

Most AI risk depends on context. The same model can be harmless in one setting and dangerous in another. A precise statement of intended use is what lets you spot misuse, scope testing and defend design decisions.

How to meet it

  • Write a system context document for each system: intended purpose, users, deployment setting, applicable laws, assumptions and out-of-scope uses.
  • List the positive and negative impacts for each stakeholder group.
  • State known limitations explicitly, such as "not validated for pediatric patients".
  • Revisit the document whenever usage expands.
Evidence an auditor will ask for
  • System context / intended-use statement
  • Stakeholder impact list
  • Documented assumptions & limitations
Link to MAP 1.1
MAP 1.2 Interdisciplinary participation is documented
NIST outcomeInterdisciplinary AI actors, competencies, skills, and capacities for establishing context reflect demographic diversity and broad domain and user experience expertise, and their participation is documented. Opportunities for interdisciplinary collaboration are prioritized.

Why it matters

Context-setting done only by builders reflects only the builders' view. Domain experts and representative users surface the real-world conditions, edge cases and harms that determine whether a system is safe to deploy.

How to meet it

  • Include domain experts, end users and compliance staff in context-setting workshops.
  • Document who took part and what expertise each person brought.
  • Find gaps in expertise and fill them with advisors or external reviewers.
  • Make cross-functional context review a required step before design approval.
Evidence an auditor will ask for
  • Workshop attendance & outputs
  • Expertise gap analysis
Link to MAP 1.2
MAP 1.3 Mission and AI goals are documented
NIST outcomeThe organization's mission and relevant goals for AI technology are understood and documented.

Why it matters

AI projects that are not tied to a mission tend to drift toward whatever is technically interesting. Anchoring each system to organizational goals makes it possible to judge whether its risks are worth taking.

How to meet it

  • Publish an AI strategy or principles document tied to the company mission.
  • Require each AI project charter to state which goal it serves.
  • Reject or deprioritize projects that cannot show alignment.
Evidence an auditor will ask for
  • AI strategy / principles
  • Project charters with goal alignment
Link to MAP 1.3
MAP 1.4 Business value is defined or re-evaluated
NIST outcomeThe business value or context of business use has been clearly defined or – in the case of assessing existing AI systems – re-evaluated.

Why it matters

Every AI risk decision is a cost-benefit tradeoff. If you cannot say what value the system delivers, you cannot decide whether a risk is acceptable. Systems that were already deployed often outlive the business case that justified them.

How to meet it

  • Define success metrics for each system, such as hours saved, accuracy gain or revenue impact.
  • Measure actual value after deployment and compare it to the original case.
  • Re-evaluate the value of legacy AI systems during periodic reviews.
  • Retire systems whose value no longer justifies their risk.
Evidence an auditor will ask for
  • Business case with success metrics
  • Post-deployment value review
Link to MAP 1.4
MAP 1.5 Risk tolerances are determined
NIST outcomeOrganizational risk tolerances are determined and documented.

Why it matters

Without explicit tolerances, "acceptable" is decided case by case and inconsistently. Documented tolerances, such as a maximum error rate, maximum disparity between groups or acceptable downtime, turn subjective debates into measurable criteria.

How to meet it

  • Translate the organizational AI risk appetite (GOVERN 1.3) into system-level thresholds.
  • Set quantitative tolerances where you can, for example false-negative rate under 2% or a demographic parity gap under 5 points.
  • Document qualitative tolerances where metrics do not exist.
  • Have system owners and risk owners agree to the thresholds.
Evidence an auditor will ask for
  • System-level risk tolerance thresholds
  • Approval records
Link to MAP 1.5
MAP 1.6 System requirements reflect socio-technical implications
NIST outcomeSystem requirements (e.g., "the system shall respect the privacy of its users") are elicited from and understood by relevant AI actors. Design decisions take socio-technical implications into account to address AI risks.

Why it matters

Trustworthiness has to be designed in. Requirements such as privacy, explainability and human override are far cheaper to build at the start than to retrofit once a model is in production.

How to meet it

  • Elicit non-functional requirements for privacy, security, fairness, explainability and oversight alongside functional ones.
  • Write them as testable "shall" statements and trace each one to a test.
  • Review design decisions for socio-technical effects, such as how a UI choice influences user trust or reliance.
Evidence an auditor will ask for
  • Requirements specification
  • Requirements-to-test traceability
Link to MAP 1.6
MP-2

Categorization of the AI system is performed.

MAP 2.1 Tasks and methods are defined
NIST outcomeThe specific tasks and methods used to implement the tasks that the AI system will support are defined (e.g., classifiers, generative models, recommenders).

Why it matters

Different AI techniques fail differently. Classifiers produce false positives, generative models hallucinate and can be prompt-injected, recommenders create feedback loops, and agents take unintended actions. Knowing the method tells you which risks and tests apply.

How to meet it

  • Record the task type and technique for each system: classification, regression, generative, retrieval-augmented generation, agentic with tool use, and so on.
  • Map each technique to its known risk categories, for example using the OWASP Top 10 for LLM Applications for generative and agentic systems.
  • Record the architecture: model, retrieval sources, tools and permissions.
Evidence an auditor will ask for
  • System technical description
  • Technique-to-risk mapping
  • Architecture diagram
Link to MAP 2.1
MAP 2.2 Knowledge limits and human use of outputs are documented
NIST outcomeInformation about the AI system's knowledge limits and how system output may be utilized and overseen by humans is documented. Documentation provides sufficient information to assist relevant AI actors when making decisions and taking subsequent actions.

Why it matters

Users over-trust AI output, especially fluent generative output. Documenting what the system does not know, such as its training cutoff, out-of-distribution inputs and unsupported languages, helps people decide when to rely on it and when to check.

How to meet it

  • Document knowledge limits: data cutoff, populations and languages covered, known weak spots.
  • Give users guidance on how to use and verify outputs.
  • Show limitations in the interface: confidence indicators, citations, "AI-generated" labels.
  • Explain to operators how to escalate uncertain cases.
Evidence an auditor will ask for
  • Model card limitations section
  • User guidance
  • UI disclosure screenshots
Link to MAP 2.2
MAP 2.3 Scientific integrity and TEVV considerations are documented
NIST outcomeScientific integrity and TEVV considerations are identified and documented, including those related to experimental design, data collection and selection (e.g., availability, representativeness, suitability), system trustworthiness, and construct validation.

Why it matters

Weak data and weak experimental design produce models that look good on paper and fail in production. Construct validity, meaning whether you are measuring what you think you are measuring, is where many AI systems quietly go wrong.

How to meet it

  • Document data provenance, collection method, representativeness and known gaps (datasheets for datasets).
  • Check that labels and target variables actually represent the intended concept. Using "arrests" as a stand-in for "crime" is the classic failure.
  • Design evaluations with held-out, deployment-representative data.
  • Have someone who did not build the model review the methodology for High-tier systems.
Evidence an auditor will ask for
  • Dataset datasheets
  • Evaluation design document
  • Methodology review notes
Link to MAP 2.3
MP-3

AI capabilities, targeted usage, goals, and expected benefits and costs compared with appropriate benchmarks are understood.

MAP 3.1 Potential benefits are documented
NIST outcomePotential benefits of intended AI system functionality and performance are examined and documented.

Why it matters

Risk management is not risk avoidance. Documenting benefits concretely, and against a baseline, lets you weigh them honestly against costs instead of letting hype or fear decide.

How to meet it

  • Quantify expected benefits against the current non-AI baseline.
  • Say who receives each benefit; it is not always the people who bear the risk.
  • Check the claimed benefits against pilot data before scaling.
Evidence an auditor will ask for
  • Benefits analysis vs. baseline
  • Pilot results
Link to MAP 3.1
MAP 3.2 Potential costs of errors are documented
NIST outcomePotential costs, including non-monetary costs, which result from expected or realized AI errors or system functionality and trustworthiness – as connected to organizational risk tolerance – are examined and documented.

Why it matters

Every model makes mistakes. What matters is what a mistake costs and who pays for it. A wrongly denied claim, a missed diagnosis or a defamatory output costs far more than the compute bill, and many of those costs are not financial.

How to meet it

  • Analyze error types: what happens on a false positive, a false negative or a hallucination.
  • Estimate the financial, safety, legal, reputational and human-dignity cost of each.
  • Compare the expected costs with your documented risk tolerance (MAP 1.5).
  • Include the cost of oversight and remediation in the total.
Evidence an auditor will ask for
  • Error-cost analysis
  • Comparison to risk tolerance
Link to MAP 3.2
MAP 3.3 Application scope is specified
NIST outcomeTargeted application scope is specified and documented based on the system's capability, established context, and AI system categorization.

Why it matters

Scope creep is one of the most common sources of AI harm: a tool validated for one population or task gets quietly used for another. A written scope sets the boundary for validation and for acceptable use.

How to meet it

  • Write in-scope and out-of-scope uses into the system documentation and user terms.
  • Enforce scope technically where possible with input validation, access controls and system prompts.
  • Require re-assessment before the system is used outside its documented scope.
Evidence an auditor will ask for
  • Scope statement
  • Technical scope controls
  • Re-assessment triggers
Link to MAP 3.3
MAP 3.4 Operator proficiency is defined and assessed
NIST outcomeProcesses for operator and practitioner proficiency with AI system performance and trustworthiness – and relevant technical standards and certifications – are defined, assessed, and documented.

Why it matters

Human oversight only works if the human is competent. An operator who does not understand a system's failure modes cannot catch them and will defer to the machine.

How to meet it

  • Define the competencies operators need for each High-tier system.
  • Train operators and verify proficiency before granting access.
  • Track relevant certifications and standards for the domain.
  • Re-verify proficiency after major system changes.
Evidence an auditor will ask for
  • Competency requirements
  • Operator training & proficiency records
Link to MAP 3.4
MAP 3.5 Human oversight processes are defined
NIST outcomeProcesses for human oversight are defined, assessed, and documented in accordance with organizational policies from the GOVERN function.

Why it matters

This puts the oversight policy from GOVERN 3.2 into practice for a specific system. It ensures each deployed system has a defined way for humans to monitor, intervene and override it, and that this mechanism has been tested.

How to meet it

  • Document the oversight workflow for each system: what is reviewed, by whom, when and with what authority.
  • Build technical override and stop mechanisms.
  • Test the oversight process, for example by injecting known-bad outputs and checking that reviewers catch them.
Evidence an auditor will ask for
  • Oversight procedure per system
  • Override mechanism
  • Oversight effectiveness test results

Risks and benefits are mapped for all components of the AI system including third-party software and data.

MAP 4.1 Component technology and legal risks are mapped
NIST outcomeApproaches for mapping AI technology and legal risks of its components – including the use of third-party data or software – are in place, followed, and documented, as are risks of infringement of a third party's intellectual property or other rights.

Why it matters

An AI system is a supply chain: base model, fine-tuning data, embeddings, vector database, plugins, orchestration libraries and APIs. A poisoned dataset, a malicious model file or an unlicensed corpus anywhere in that chain becomes your problem.

How to meet it

  • Build an AI-BOM for each system listing models, datasets, libraries, tools and services, with version and source.
  • Scan model artifacts, for example for unsafe pickle serialization, and verify their provenance.
  • Review dataset and model licenses and copyright exposure.
  • Map each component to its technical and legal risks.
Evidence an auditor will ask for
  • AI-BOM
  • Model scanning results
  • License/IP review
Link to MAP 4.1
MAP 4.2 Internal controls for components are documented
NIST outcomeInternal risk controls for components of the AI system, including third-party AI technologies, are identified and documented.

Why it matters

Once component risks are known, each needs a matching control. Documenting the controls shows coverage and exposes components that are trusted by default.

How to meet it

  • Map controls to each component risk: model version pinning, output filtering, least-privilege tool permissions, data validation and so on.
  • Flag components with no compensating control.
  • Include AI component controls in your existing control framework (SOC 2, ISO 27001, HITRUST).
Evidence an auditor will ask for
  • Component control matrix
  • Gap list
Link to MAP 4.2
MP-5

Impacts to individuals, groups, communities, organizations, and society are characterized.

MAP 5.1 Likelihood and magnitude of impacts are documented
NIST outcomeLikelihood and magnitude of each identified impact (both potentially beneficial and harmful) based on expected use, past uses of AI systems in similar contexts, public incident reports, feedback from those external to the team that developed or deployed the AI system, or other data are identified and documented.

Why it matters

This is where impacts become ratable risks. Using evidence such as public incident databases and similar deployments, rather than intuition, makes the ratings defensible and comparable across systems.

How to meet it

  • Rate each impact on likelihood and severity using a standard scale.
  • Draw on external evidence: the AI Incident Database, regulator actions and peer incidents.
  • Record the rationale for each rating.
  • Feed the rated impacts into the risk register.
Evidence an auditor will ask for
  • Impact assessment with ratings
  • Evidence sources cited
  • Risk register entries
Link to MAP 5.1
MAP 5.2 Regular engagement on impacts is resourced
NIST outcomePractices and personnel for supporting regular engagement with relevant AI actors and integrating feedback about positive, negative, and unanticipated impacts are in place and documented.

Why it matters

Impacts change after deployment and some only appear at scale. Ongoing engagement with users and affected groups, backed by named people and a budget, is how unanticipated impacts get detected.

How to meet it

  • Assign staff responsible for stakeholder engagement on High-tier systems.
  • Schedule recurring engagement such as surveys, panels or user interviews.
  • Route findings into impact re-assessment.
Evidence an auditor will ask for
  • Engagement plan & owners
  • Engagement records
Link to MAP 5.2

Measure

Identified risks are assessed, analyzed, or tracked

MEASURE uses quantitative and qualitative methods (testing, evaluation, verification and validation, or TEVV) to analyze the risks MAP identified. It produces the evidence that trustworthiness claims are true, and keeps checking them in production.

MS-1

Appropriate methods and metrics are identified and applied.

MEASURE 1.1 Metrics are selected, starting with the most significant risks
NIST outcomeApproaches and metrics for measurement of AI risks enumerated during the MAP function are selected for implementation starting with the most significant AI risks. The risks or trustworthiness characteristics that will not – or cannot – be measured are properly documented.

Why it matters

You cannot measure everything, so measure what matters most first. Documenting what you are not measuring is just as important: an unmeasured risk that is acknowledged is manageable, while one that is ignored is a hidden liability.

How to meet it

  • Pick metrics for each top-ranked risk, such as accuracy by subgroup, hallucination rate, jailbreak success rate or PII leakage rate.
  • Prioritize measurement effort by risk rating.
  • Keep a list of risks that are not measured, with the reason and any compensating controls.
Evidence an auditor will ask for
  • Measurement plan
  • Unmeasured-risk register
Link to MEASURE 1.1
MEASURE 1.2 Metric appropriateness and control effectiveness are reassessed
NIST outcomeAppropriateness of AI metrics and effectiveness of existing controls are regularly assessed and updated, including reports of errors and potential impacts on affected communities.

Why it matters

Metrics go stale. A benchmark the model now saturates, or an aggregate accuracy figure that hides subgroup failures, gives false comfort. Controls lose effectiveness too as attackers adapt.

How to meet it

  • Review metric suitability during periodic system reviews.
  • Test controls such as guardrails and filters against current attack techniques.
  • Bring error reports and community feedback into the metric review.
  • Retire or replace metrics that no longer distinguish good from bad performance.
Evidence an auditor will ask for
  • Metric review records
  • Control effectiveness test results
Link to MEASURE 1.2
MEASURE 1.3 Independent assessors are involved
NIST outcomeInternal experts who did not serve as front-line developers for the system and/or independent assessors are involved in regular assessments and updates. Domain experts, users, AI actors external to the team that developed or deployed the AI system, and affected communities are consulted in support of assessments as necessary per organizational risk tolerance.

Why it matters

Builders are the worst-placed people to find their own blind spots. Independence is a basic assurance principle in financial audit and security testing, and it applies to AI evaluation as well.

How to meet it

  • Require evaluation by someone outside the build team for High-tier systems, either an internal assurance team or a third party.
  • Commission external red teaming or audits proportionate to risk.
  • Include domain experts and user representatives in evaluation design.
Evidence an auditor will ask for
  • Independent assessment reports
  • Assessor independence attestation
Link to MEASURE 1.3
MS-2

AI systems are evaluated for trustworthy characteristics.

MEASURE 2.1 TEVV test sets, metrics and tools are documented
NIST outcomeTest sets, metrics, and details about the tools used during TEVV are documented.

Why it matters

An evaluation result is only as credible as its method. If you cannot say which data, metrics and tools produced a number, nobody can reproduce, compare or trust it.

How to meet it

  • Version-control evaluation datasets, prompts and harness code.
  • Document each metric's definition and its known limitations.
  • Record tool versions and configurations.
  • Store evaluation runs with full lineage in an experiment tracker or eval platform.
Evidence an auditor will ask for
  • Evaluation documentation
  • Versioned test sets
  • Experiment tracking records
Link to MEASURE 2.1
MEASURE 2.2 Human-subject evaluations are protected and representative
NIST outcomeEvaluations involving human subjects meet applicable requirements (including human subject protection) and are representative of the relevant population.

Why it matters

User studies, A/B tests and annotation work involve real people. They need consent and privacy protection, and the evaluation population must match the deployment population or the results will not hold up.

How to meet it

  • Get informed consent and follow IRB or ethics review where it applies.
  • Protect participant data under your privacy program.
  • Check that evaluation participants represent the deployment population.
  • Ensure fair treatment and pay for annotators and raters.
Evidence an auditor will ask for
  • Consent forms / IRB approvals
  • Participant demographics vs. deployment population
Link to MEASURE 2.2
MEASURE 2.3 Performance is demonstrated under deployment-like conditions
NIST outcomeAI system performance or assurance criteria are measured qualitatively or quantitatively and demonstrated for conditions similar to deployment setting(s). Measures are documented.

Why it matters

Lab performance rarely survives contact with production. Real inputs are messier and more varied and include adversarial users. Testing must reflect deployment reality to mean anything.

How to meet it

  • Evaluate on data drawn from, or closely resembling, the production distribution.
  • Include edge cases, noisy inputs and the full range of user behavior.
  • Run shadow-mode or limited pilots before full rollout.
  • Document results against the acceptance criteria.
Evidence an auditor will ask for
  • Deployment-representative evaluation results
  • Pilot / shadow-mode reports
Link to MEASURE 2.3
MEASURE 2.4 Production behavior is monitored
NIST outcomeThe functionality and behavior of the AI system and its components – as identified in the MAP function – are monitored when in production.

Why it matters

Data drift, concept drift, upstream model updates and changing user behavior all degrade AI systems silently. Without monitoring, you find out from customers.

How to meet it

  • Monitor input distributions, output distributions, performance metrics and error rates.
  • For LLM applications, log prompts and responses (with privacy controls) and watch for jailbreak attempts, refusal rates and toxic output.
  • Set alert thresholds tied to risk tolerances.
  • Assign on-call responsibility for AI alerts.
Evidence an auditor will ask for
  • Monitoring dashboards
  • Alert configurations
  • Alert response records
Link to MEASURE 2.4
MEASURE 2.5 Validity and reliability are demonstrated
NIST outcomeThe AI system to be deployed is demonstrated to be valid and reliable. Limitations of the generalizability beyond the conditions under which the technology was developed are documented.

Why it matters

Validity asks whether the system does what it claims. Reliability asks whether it does so consistently. Both must be shown with evidence before deployment, and the limits of that evidence must be stated plainly.

How to meet it

  • Validate against the requirements and acceptance criteria from MAP.
  • Test consistency: repeated runs, paraphrased inputs and minor perturbations, which matter especially for non-deterministic LLMs.
  • Document where generalization has not been demonstrated.
Evidence an auditor will ask for
  • Validation report
  • Consistency/reliability test results
  • Generalizability limitations
Link to MEASURE 2.5
MEASURE 2.6 Safety is evaluated and the system fails safely
NIST outcomeThe AI system is evaluated regularly for safety risks – as identified in the MAP function. The AI system to be deployed is demonstrated to be safe, its residual negative risk does not exceed the risk tolerance, and it can fail safely, particularly if made to operate beyond its knowledge limits. Safety metrics reflect system reliability and robustness, real-time monitoring, and response times for AI system failures.

Why it matters

Failure is certain at some point. What matters is how the system fails. A system that confidently answers outside its competence is dangerous, while one that abstains or escalates is safe. This matters most in healthcare, physical systems and agentic AI that takes actions.

How to meet it

  • Run safety evaluations for harmful-output scenarios identified in MAP.
  • Build fail-safe behavior: abstention on low confidence, escalation to humans, rate limits and action confirmation for agents.
  • Test behavior on out-of-distribution and beyond-scope inputs.
  • Measure detection and response times for safety failures.
Evidence an auditor will ask for
  • Safety evaluation results
  • Fail-safe design documentation
  • Response-time metrics
Link to MEASURE 2.6
MEASURE 2.7 Security and resilience are evaluated
NIST outcomeAI system security and resilience – as identified in the MAP function – are evaluated and documented.

Why it matters

AI adds attack surface that traditional security testing misses: prompt injection (direct and indirect), data poisoning, model extraction, membership inference, insecure tool use by agents and sensitive data disclosure. Attackers are actively exploiting these.

How to meet it

  • Threat-model each system using MITRE ATLAS and the OWASP Top 10 for LLM Applications.
  • Run AI red teaming covering jailbreaks, prompt injection, data exfiltration and tool abuse, using both automated tools and human testers.
  • Test resilience to adversarial inputs and recovery from compromise.
  • Include AI components in penetration tests and vulnerability management.
Evidence an auditor will ask for
  • AI threat model
  • Red-team / pentest reports
  • Remediation tracking
Link to MEASURE 2.7
MEASURE 2.8 Transparency and accountability risks are examined
NIST outcomeRisks associated with transparency and accountability – as identified in the MAP function – are examined and documented.

Why it matters

If people cannot tell they are dealing with AI, or cannot find out who is responsible for an outcome, they cannot contest it, and you cannot defend it. Transparency obligations are also among the most common AI regulatory requirements, including chatbot disclosure and deepfake labeling.

How to meet it

  • Check that AI interactions and AI-generated content are disclosed where required or expected.
  • Confirm that decisions are traceable to a system version, input and accountable owner.
  • Keep audit logs adequate for after-the-fact reconstruction.
  • Document any transparency gaps and how they are mitigated.
Evidence an auditor will ask for
  • Disclosure review
  • Audit log samples
  • Traceability documentation
Link to MEASURE 2.8
MEASURE 2.9 Model is explained and outputs are interpreted in context
NIST outcomeThe AI model is explained, validated, and documented, and AI system output is interpreted within its context – as identified in the MAP function – to inform responsible use and governance.

Why it matters

Explainability lets operators catch errors, lets affected people understand decisions and lets developers debug. It is increasingly required by law for consequential decisions, for example adverse-action notices in credit and the EU AI Act's transparency provisions.

How to meet it

  • Choose explanation methods suited to the model and the audience, such as feature attribution, counterfactuals, citations for RAG or reasoning summaries.
  • Check that explanations are faithful to the model and not just plausible.
  • Give decision-specific explanations to affected individuals where required.
  • Document how outputs should and should not be interpreted.
Evidence an auditor will ask for
  • Explainability approach
  • Sample explanations
  • Interpretation guidance
Link to MEASURE 2.9
MEASURE 2.10 Privacy risk is examined
NIST outcomePrivacy risk of the AI system – as identified in the MAP function – is examined and documented.

Why it matters

AI systems memorize training data, infer sensitive attributes, combine data in new ways and can leak personal information through outputs. Privacy law (GDPR, HIPAA, CCPA) applies fully to AI, and the fines are real.

How to meet it

  • Run a DPIA or privacy impact assessment for systems that process personal data.
  • Test for training-data memorization and PII leakage in outputs.
  • Apply data minimization, de-identification and privacy-enhancing technologies where feasible.
  • Confirm a lawful basis and honor data-subject rights, including deletion from training data where applicable.
Evidence an auditor will ask for
  • DPIA / PIA
  • PII leakage test results
  • Data minimization controls
Link to MEASURE 2.10
MEASURE 2.11 Fairness and bias are evaluated
NIST outcomeFairness and bias – as identified in the MAP function – are evaluated and results are documented.

Why it matters

AI can encode and amplify historical discrimination at scale. Biased outcomes in hiring, lending, housing, healthcare and insurance create legal liability under anti-discrimination law and laws such as NYC Local Law 144 and the Colorado AI Act, as well as serious reputational harm.

How to meet it

  • Pick fairness metrics suited to the context, such as demographic parity, equalized odds or calibration, and record why.
  • Evaluate performance across relevant subgroups, including intersectional ones.
  • Address statistical, systemic and human-cognitive sources of bias, not only the data.
  • Document results, mitigations and residual disparities, and commission bias audits where the law requires them.
Evidence an auditor will ask for
  • Bias evaluation report
  • Subgroup performance metrics
  • Bias audit (where required)
Link to MEASURE 2.11
MEASURE 2.12 Environmental impact is assessed
NIST outcomeEnvironmental impact and sustainability of AI model training and management activities – as identified in the MAP function – are assessed and documented.

Why it matters

Training and serving large models consumes significant energy and water. Stakeholders, ESG reporting frameworks and some regulations, including documentation duties for general-purpose AI under the EU AI Act, increasingly expect this footprint to be measured.

How to meet it

  • Estimate the energy and carbon cost of training and inference, using provider sustainability data where you can.
  • Consider right-sized models: a smaller model that meets requirements is often cheaper and greener.
  • Include AI workloads in sustainability reporting.
Evidence an auditor will ask for
  • Compute/energy estimates
  • Model-sizing rationale
Link to MEASURE 2.12
MEASURE 2.13 TEVV effectiveness is evaluated
NIST outcomeEffectiveness of the employed TEVV metrics and processes in the MEASURE function are evaluated and documented.

Why it matters

This is the meta-control: is your testing actually catching problems? If production incidents keep happening that evaluation should have caught, the evaluation program needs fixing.

How to meet it

  • Compare pre-deployment findings with production incidents and look for escapes.
  • Run root-cause analysis on escapes and update test suites.
  • Benchmark your evaluation practices against emerging standards and peers once a year.
Evidence an auditor will ask for
  • TEVV effectiveness review
  • Escape analysis
  • Test-suite updates
Link to MEASURE 2.13
MS-3

Mechanisms for tracking identified AI risks over time are in place.

MEASURE 3.1 Existing, unanticipated and emergent risks are tracked
NIST outcomeApproaches, personnel, and documentation are in place to regularly identify and track existing, unanticipated, and emergent AI risks based on factors such as intended and actual performance in deployed contexts.

Why it matters

The risk picture at launch is incomplete. New risks appear through use: novel jailbreaks, unexpected user behavior, emergent capabilities after a model upgrade. Someone has to be watching for them.

How to meet it

  • Assign owners to track risks for each system throughout its life.
  • Compare actual production performance against what was intended.
  • Track external developments such as new attack techniques, incidents at peers and regulatory changes.
  • Update the risk register when new risks appear.
Evidence an auditor will ask for
  • Risk register update history
  • Emerging-risk watch reports
Link to MEASURE 3.1
MEASURE 3.2 Hard-to-measure risks are still tracked
NIST outcomeRisk tracking approaches are considered for settings where AI risks are difficult to assess using currently available measurement techniques or where metrics are not yet available.

Why it matters

Some of the most important AI risks, such as long-term societal effects, subtle manipulation or harm from agent autonomy, have no mature metrics. Lack of a metric does not mean lack of a risk.

How to meet it

  • Use qualitative methods: expert judgment, scenario analysis, structured user interviews and incident tracking.
  • Define proxy indicators where direct measurement is impossible.
  • Apply more conservative controls where measurement is weak.
Evidence an auditor will ask for
  • Qualitative risk assessments
  • Proxy indicator definitions
Link to MEASURE 3.2
MEASURE 3.3 End users can report problems and appeal outcomes
NIST outcomeFeedback processes for end users and impacted communities to report problems and appeal system outcomes are established and integrated into AI system evaluation metrics.

Why it matters

People affected by AI decisions need recourse, and their reports are a valuable source of detection. Appeal mechanisms are also a legal requirement in many contexts, including GDPR Article 22 and several U.S. state AI laws.

How to meet it

  • Provide a clear way to report problems and request human review of AI decisions.
  • Set response and resolution times.
  • Track appeal volumes and overturn rates as evaluation metrics. A high overturn rate is a red flag.
  • Feed appeal outcomes back into model improvement.
Evidence an auditor will ask for
  • Appeal/feedback process
  • Appeal metrics
  • Overturn analysis
Link to MEASURE 3.3
MS-4

Feedback about efficacy of measurement is gathered and assessed.

MEASURE 4.1 Measurement is tied to deployment context
NIST outcomeMeasurement approaches for identifying AI risks are connected to deployment context(s) and informed through consultation with domain experts and other end users. Approaches are documented.

Why it matters

Generic benchmarks say little about whether a system is safe for your patients, customers or use case. Domain experts know what "good" looks like in context and which errors matter most.

How to meet it

  • Design context-specific evaluations with domain experts, for example a clinician-reviewed rubric for medical summaries.
  • Weight metrics by real-world error cost.
  • Document why the chosen approach fits the deployment context.
Evidence an auditor will ask for
  • Context-specific evaluation design
  • Domain expert input records
Link to MEASURE 4.1
MEASURE 4.2 Results are validated by domain experts
NIST outcomeMeasurement results regarding AI system trustworthiness in deployment context(s) and across the AI lifecycle are informed by input from domain experts and relevant AI actors to validate whether the system is performing consistently as intended. Results are documented.

Why it matters

Numbers need interpretation. A 95% accuracy figure may be excellent or unacceptable depending on context, and only domain experts can tell which. Their review confirms the system works as intended in practice.

How to meet it

  • Have domain experts review evaluation results and production samples on a regular schedule.
  • Use expert review to calibrate automated metrics, including LLM-as-judge setups.
  • Document the conclusions and any disagreements.
Evidence an auditor will ask for
  • Expert review sign-offs
  • Calibration studies
Link to MEASURE 4.2
MEASURE 4.3 Performance changes are identified and documented
NIST outcomeMeasurable performance improvements or declines based on consultations with relevant AI actors, including affected communities, and field data about context-relevant risks and trustworthiness characteristics are identified and documented.

Why it matters

Trend data shows whether your risk treatments are working and whether the system is getting better or worse. It is also what you show auditors and boards to demonstrate that the program is effective.

How to meet it

  • Track trustworthiness metrics over time, release over release.
  • Combine field data with stakeholder input when interpreting trends.
  • Report material changes to the system owner and the governance committee.
Evidence an auditor will ask for
  • Trend reports
  • Release-over-release comparisons
Link to MEASURE 4.3

Manage

Risks are prioritized and acted upon based on projected impact

MANAGE turns the findings from MAP and MEASURE into decisions and action: whether to deploy, which risks to treat, how to respond when things go wrong and how to keep improving. This is where governance produces outcomes.

MG-1

AI risks based on assessments and other analytical output from the MAP and MEASURE functions are prioritized, responded to, and managed.

MANAGE 1.1 Go / no-go decision is made
NIST outcomeA determination is made as to whether the AI system achieves its intended purposes and stated objectives and whether its development or deployment should proceed.

Why it matters

Every AI program needs a real decision point where "no" is a possible answer. Without one, sunk-cost momentum carries flawed systems into production.

How to meet it

  • Hold a formal deployment review: does the system meet its objectives and acceptance criteria, and is residual risk within tolerance?
  • Define the decision authority by risk tier.
  • Record the decision, its rationale and any conditions such as limited rollout or extra monitoring.
  • Repeat the review at major changes.
Evidence an auditor will ask for
  • Go/no-go decision record
  • Deployment review package
Link to MANAGE 1.1
MANAGE 1.2 Risk treatment is prioritized
NIST outcomeTreatment of documented AI risks is prioritized based on impact, likelihood, and available resources or methods.

Why it matters

Resources are finite. Prioritizing by impact and likelihood keeps effort on the risks that could do the most damage instead of the ones that are easiest to fix.

How to meet it

  • Rank risks in the register by rating.
  • Set remediation deadlines by severity, for example Critical in 30 days and High in 90.
  • Allocate budget and staff to the top risks.
  • Review prioritization when new risks are added.
Evidence an auditor will ask for
  • Prioritized risk register
  • Remediation SLAs
  • Resourcing decisions
Link to MANAGE 1.2
MANAGE 1.3 High-priority risk responses are planned
NIST outcomeResponses to the AI risks deemed high priority, as identified by the MAP function, are developed, planned, and documented. Risk response options can include mitigating, transferring, avoiding, or accepting.

Why it matters

Every significant risk needs a deliberate response, even if that response is to accept it. Documented treatment plans make sure high risks are not just recorded and forgotten.

How to meet it

  • For each high-priority risk, choose a response: mitigate (add controls), transfer (insurance or contract), avoid (change the design or do not deploy) or accept (with sign-off).
  • Write a treatment plan with actions, owners and dates.
  • Track plans through to completion and verify their effectiveness.
Evidence an auditor will ask for
  • Risk treatment plans
  • Risk acceptance forms
  • Completion verification
Link to MANAGE 1.3
MANAGE 1.4 Residual risks are documented for downstream users
NIST outcomeNegative residual risks (defined as the sum of all unmitigated risks) to both downstream acquirers of AI systems and end users are documented.

Why it matters

Whatever risk remains after treatment passes to customers and users. They deserve to know about it, and documenting it protects you when known limitations later cause problems. The EU AI Act requires providers of high-risk systems to communicate residual risks to deployers.

How to meet it

  • Summarize residual risks per system after treatment.
  • Communicate them to downstream deployers through documentation, contracts or instructions for use.
  • Make relevant residual risks visible to end users where they affect how the system should be used.
Evidence an auditor will ask for
  • Residual risk statement
  • Customer-facing documentation / instructions for use
Link to MANAGE 1.4
MG-2

Strategies to maximize AI benefits and minimize negative impacts are planned, prepared, implemented, documented, and informed by input from relevant AI actors.

MANAGE 2.1 Resources and non-AI alternatives are considered
NIST outcomeResources required to manage AI risks are taken into account – along with viable non-AI alternative systems, approaches, or methods – to reduce the magnitude or likelihood of potential impacts.

Why it matters

Sometimes the best risk control is not using AI at all. If the cost of managing a system's risks exceeds its value, or a rules-based approach works just as well, that option has to be on the table.

How to meet it

  • Estimate the full cost of risk management per system: oversight, monitoring, evaluation and remediation.
  • Compare against non-AI or simpler alternatives in the business case.
  • Record why AI was chosen over the alternatives.
Evidence an auditor will ask for
  • Total cost of risk analysis
  • Alternatives analysis
Link to MANAGE 2.1
MANAGE 2.2 Mechanisms sustain deployed value
NIST outcomeMechanisms are in place and applied to sustain the value of deployed AI systems.

Why it matters

AI systems degrade without maintenance. Value at launch is not value forever. Retraining, prompt tuning, data refreshes and dependency updates are what keep the system worth its risk.

How to meet it

  • Define a maintenance plan: retraining triggers, evaluation cadence, dependency and model version updates.
  • Budget for ongoing operations, not just the build.
  • Track value metrics in production (MAP 1.4) and act when they decline.
Evidence an auditor will ask for
  • Maintenance plan
  • Retraining/update records
  • Value tracking
Link to MANAGE 2.2
MANAGE 2.3 Unknown risks are responded to and recovered from
NIST outcomeProcedures are followed to respond to and recover from a previously unknown risk when it is identified.

Why it matters

Some risks will only show up in production. A new jailbreak technique or an unexpected failure mode needs a defined response path, or teams will improvise under pressure.

How to meet it

  • Extend incident response procedures to cover newly discovered AI risks, not only incidents that have already happened.
  • Define rapid-response options: tighten guardrails, restrict features, roll back the model or pause the system.
  • Run tabletop exercises on AI-specific scenarios.
  • Hold a post-incident review and update the risk register.
Evidence an auditor will ask for
  • AI incident/risk response procedure
  • Tabletop exercise records
  • Post-incident reviews
Link to MANAGE 2.3
MANAGE 2.4 Systems can be superseded, disengaged or deactivated
NIST outcomeMechanisms are in place and applied, and responsibilities are assigned and understood, to supersede, disengage, or deactivate AI systems that demonstrate performance or outcomes inconsistent with intended use.

Why it matters

You need a kill switch, and someone with the authority and knowledge to use it. When an AI system starts causing harm, every hour of delay increases the damage. This matters most for autonomous agents that can take actions.

How to meet it

  • Build technical shut-off and rollback mechanisms such as feature flags, model routing and agent permission revocation.
  • Define the criteria for disengaging a system and who has authority to do it.
  • Make sure a fallback process exists so the business keeps running.
  • Test the kill switch.
Evidence an auditor will ask for
  • Kill-switch / rollback mechanism
  • Deactivation criteria & authority
  • Test records
Link to MANAGE 2.4
MG-3

AI risks and benefits from third-party entities are managed.

MANAGE 3.1 Third-party AI risks are monitored and controlled
NIST outcomeAI risks and benefits from third-party resources are regularly monitored, and risk controls are applied and documented.

Why it matters

Vendor due diligence at purchase (GOVERN 6.1) is not enough. Vendors change models, terms, sub-processors and security posture after you sign. Ongoing monitoring catches those changes.

How to meet it

  • Reassess AI vendors periodically according to risk tier.
  • Watch for vendor model updates, terms-of-service changes and security incidents.
  • Apply compensating controls in your own environment, such as output filtering, data redaction before API calls and usage monitoring.
  • Track vendor AI risk in the third-party risk management program.
Evidence an auditor will ask for
  • Vendor reassessments
  • Vendor change log
  • Compensating controls
Link to MANAGE 3.1
MANAGE 3.2 Pre-trained models are monitored
NIST outcomePre-trained models which are used for development are monitored as part of AI system regular monitoring and maintenance.

Why it matters

Foundation and open-weight models carry inherited risks such as training-data bias, embedded vulnerabilities, backdoors and license changes, and new problems with them are discovered all the time. Fine-tuning does not remove these risks.

How to meet it

  • Track every pre-trained model in the AI-BOM with version and source.
  • Monitor advisories, published vulnerabilities and research about the models you use.
  • Re-evaluate when the base model is updated or a new issue is disclosed.
  • Pin versions in production and test upgrades before rollout.
Evidence an auditor will ask for
  • Pre-trained model register
  • Advisory monitoring
  • Upgrade evaluation records
Link to MANAGE 3.2
MG-4

Risk treatments, including response and recovery, and communication plans for the identified and measured AI risks are documented and monitored regularly.

MANAGE 4.1 Post-deployment monitoring plans are implemented
NIST outcomePost-deployment AI system monitoring plans are implemented, including mechanisms for capturing and evaluating input from users and other relevant AI actors, appeal and override, decommissioning, incident response, recovery, and change management.

Why it matters

This outcome brings post-deployment operations together into one plan per system. It is the operational runbook that shows the system is governed in production and not just at launch.

How to meet it

  • Write a post-deployment plan per system covering monitoring, feedback intake, appeals and overrides, incident response, change management and decommissioning triggers.
  • Link the plan to the existing ITSM and change processes.
  • Review the plan during periodic system reviews.
Evidence an auditor will ask for
  • Post-deployment monitoring plan
  • Change management records
Link to MANAGE 4.1
MANAGE 4.2 Continual improvement is built into updates
NIST outcomeMeasurable activities for continual improvements are integrated into AI system updates and include regular engagement with interested parties, including relevant AI actors.

Why it matters

Risk management should make systems better over time, not just keep them from getting worse. Building measurable improvement goals into each release cycle shows the program is effective and keeps stakeholders engaged.

How to meet it

  • Set improvement targets for trustworthiness metrics in each release.
  • Include stakeholder feedback themes in release planning.
  • Report progress against targets to the governance committee.
Evidence an auditor will ask for
  • Release improvement targets
  • Progress reports
Link to MANAGE 4.2
MANAGE 4.3 Incidents and errors are communicated and tracked
NIST outcomeIncidents and errors are communicated to relevant AI actors, including affected communities. Processes for tracking, responding to, and recovering from incidents and errors are followed and documented.

Why it matters

How you handle AI incidents determines whether trust survives them. Transparent communication with affected users, customers and regulators is increasingly mandatory. The EU AI Act requires providers of high-risk systems to report serious incidents, and existing breach-notification laws apply when personal data is involved.

How to meet it

  • Log all AI incidents and significant errors in a tracking system with severity, impact and root cause.
  • Define communication obligations and templates for users, customers, regulators and the board.
  • Meet regulatory notification deadlines where they apply.
  • Hold post-incident reviews and share lessons learned internally.
Evidence an auditor will ask for
  • AI incident log
  • Communication templates & records
  • Post-incident reviews

Where the AI RMF Overlaps

Building to the AI RMF gets you most of the way to ISO/IEC 42001 certification and EU AI Act readiness. This is the high-level mapping we use with clients.

A 90-Day Path to a Defensible Program

72 outcomes is a lot. This is the order we use to give clients something they can show a customer or auditor within one quarter.

30

Foundation

Inventory every AI system (GV 1.6), publish an AI policy (GV 1.2), name owners (GV 2.1) and define risk tiers (GV 1.3).

60

Context & Supply Chain

Run MAP on your high-tier systems: intended use, impacts, risk tolerances and an AI-BOM. Review AI vendors and contracts (GV 6.1, MP 4.1).

90

Evidence & Response

Red-team and evaluate (MS 2.7, MS 2.11), turn on production monitoring (MS 2.4), formalize go/no-go (MG 1.1) and an AI incident playbook (MG 4.3).

Want This Done, Not Just Explained?
