AI Risk Assessment Best Practices: Using the NIST AI RMF for Compliance
Contents
AI is shaping loan approvals, automating triage, and deciding which customers get what support. While 93% of organizations use AI, yet only 7% have embedded governance frameworks, just 4% feel prepared to support AI at scale, and oversight is often fragmented. Nearly 75% of executives emphasize the need for human oversight to manage legal and reputational risk.
Yet as AI accelerates, governance lags behind, and this lag isn’t theoretical. It’s where operational, reputational, and regulatory risk begins.
The NIST AI Risk Management Framework (AI RMF) offers a solution: a structured, practical approach to identifying, measuring, managing, and governing AI risk across diverse systems and use cases. It doesn’t just provide you with a blueprint for managing AI risks , but also highlights the architecture required to make responsible AI (RAI) operational.
What is NIST AI RMF
The NIST AI RMF is a comprehensive guide developed by the National Institute of Standards and Technology to help organizations identify, evaluate, and mitigate risks associated with AI systems. Rather than being a checklist, the AI RMF outlines a flexible, principles-based structure that integrates into every stage of the AI lifecycle.
It focuses on four core functions, and we’ll explore them below.
Why AI Risk Has Become a Leadership Imperative
AI risk isn’t only a side effect of exponential innovation and irresponsible human behavior. It’s often also a function of scale without oversight.
Systems introduced with good intent can later introduce serious harm: discrimination, data leakage, manipulation, or opacity in critical decisions. These aren’t isolated events but systemic breakdowns
The AI RMF gives executive teams a shared language to align on risk tolerance, accountability, and decision rights across legal, risk, product, and engineering teams. It elevates AI governance from a compliance task to a board-level responsibility (one that protects trust and enables resilience).

The Four Core Functions: What the NIST RMF Actually Asks You to Do
The RMF outlines four core functions that, when embedded across the AI lifecycle, create a durable governance system:
1. Govern: Is Accountability Embedded (Not Bolted On)?
Too many organizations think of governance as something to address at the end. But the AI RMF positions it as the first step, one that initiates a continuous thread through the entire AI lifecycle.
That means:
- Defining clear ownership for every AI system
- Establishing cross-functional review structures (e.g. an AI ethics committee)
- Aligning on risk tolerance and mitigation thresholds
- Running recurring evaluations of risk metrics and governance health
- Training teams across functions in risk fluency, not just compliance vocabulary
Governance is how organizations maintain continuity, accountability, and alignment as AI systems evolve. It ensures decisions remain consistent with mission, values, and changing market demands.
2. Map: Do You Know Where AI Is Already Operating?
Most organizations don’t have a full inventory of AI systems, especially when AI capabilities are embedded in third-party tools and vendor platforms.
Mapping forces visibility:
- Which systems are using AI (internally or externally)?
- What kind of data do they ingest, leverage, and access (PII, PHI, financial records)?
- What decisions do they influence, and how consequential are their outcomes?
- What regulations might apply (e.g. GDPR, HIPAA, EU AI Act)?
- What intended use cases have been identified?

3. Measure: What’s the Nature and Magnitude of Risk?
Measurement is where governance matures, from awareness to insight.
Once systems are mapped, organizations must assess how risk manifests:
- Are models exhibiting bias toward protected classes?
- Can you explain how a decision was made, and by what logic?
- Could an adversary manipulate the system’s inputs or outputs?
- How would a stakeholder be affected if the model underperformed?
Poorly performing models, unexplainable outcomes, or unmanaged data flows are signs of weak accountability structures.

4. Manage: What Controls Actually Mitigate That Risk?
Controls aren’t one-size-fits-all, and not every system needs heavy governance. But every AI system needs some level of responsible intervention.
Examples of risk mitigation mechanisms include:
- Human-in-the-loop for high-impact decisions
- Access controls for sensitive training data
- Model documentation (model cards, datasheets, lineage maps)
- Live monitoring for model drift or performance degradation
- User-facing explainability tools to support transparency
- XAI methods to improve model interpretability and support auditability across internal and regulatory reviews
The value here is alignment, ensuring your risk controls are aligned with your use cases, organizational values and objectives, model complexity, and compliance requirements.
How Risk Assessment Works in Practice: A Step-by-Step Framework
Here’s a practical blueprint that reflects how the most advanced organizations turn AI governance from theory into operational muscle.
Step 1: Operationalize Governance
- Establish quarterly risk reviews
- Embed governance checkpoints throughout the model lifecycle
- Empower AI stewards to escalate risk concerns
- Train your teams in governance principles, not just process steps
Why it matters: Governance must be cultural AND procedural. A compliant team might miss the point. A fluent team won’t.
Step 2: Inventory All AI
Identify every AI system (proprietary, vendor-supplied, or embedded in platforms). Map them to their intended purpose and use, key stakeholders, data characteristics and requirements, and the business functions and/or decisions supported.
Why it matters: You can’t govern what you can’t see. Hidden systems tend to cause the biggest surprises.
Step 3: Classify and Tier by Risk
Classify systems based on:
- Data privacy and sensitivity
- Decision consequences
- Regulatory and stakeholder impacts
- Model complexity
- Maintenance and remediation costs
- Safety and security vulnerabilities
- Objective and value alignment
- Explainability and transparency
Use this to assign risk tiers (low, medium, high) and calibrate your controls accordingly.
Why it matters: Not all AI systems are equal, and treating them like they are wastes time, resources, and trust.
Step 4: Run Targeted Risk Assessments
Use a mix of technical and human-centered evaluation:
- Fairness and bias audits across demographics
- Explainability assessments (internal and customer-facing)
- Adversarial testing and threat modeling
- Stakeholder mapping and scenario planning
Why it matters: Risk doesn’t only emerge from models. It’s shaped by how AI intersects with real-world systems and users.
Step 5: Apply and Monitor Controls
For high-risk systems:
- Implement review gates before deployment
- Require documentation and justification for key design decisions
- Activate live monitoring for drift, performance degradation, and unusual outputs
Why it matters: Controls lose value when they’re passive or outdated. They should evolve with the system they’re designed to protect.
Why the NIST AI RMF Is More Than a Compliance Tool
The AI RMF isn’t just a regulatory hedge. It’s a maturity model, a way to develop institutional discipline as AI becomes part of your core infrastructure.
It helps answer key leadership questions:
- Can we explain how AI makes decisions, and who’s accountable when it fails?
- Are we governing consistently across teams, vendors, and platforms?
- Do we have repeatable practices to identify and mitigate AI risk and could we communicate them to regulators or customers if asked?
That’s what separates organizations that “use AI” from those that deploy AI responsibly at scale.

Where Most Programs Go Wrong
| Pitfall | Insight | Solution |
|---|---|---|
| Blind spots in inventory | Missed systems create hidden risk | Conduct AI discovery audits quarterly |
| Misaligned controls | Over- or under-engineering risk responses | Use tiering to scale governance appropriately |
| Governance as a project | Short-lived compliance pushes lose momentum | Build into workflows, not just policy decks |
| Talent and tooling gaps | Most teams lack AI-specific governance skills | Upskill internally or bring in trusted partners |
Looking Ahead
On July 26, 2024, NIST released a GenAI Profile (NIST-AI-600-1) targeting risks tied to LLMs and synthetic media. New sector-specific playbooks (finance, healthcare) and global harmonization efforts (EU AI Act, ISO 42001) are in motion.
The message is clear: governance cannot be static. The AI RMF’s strength lies in its adaptability, not rigidity.
