Model Risk

The potential for harm or loss arising when a model produces inaccurate, misleading, or misapplied outputs, including losses from decisions made using those outputs.

Related: Model Inventory, Model Validation, Concept Drift
Algorithmic Bias

Systematic and repeatable errors in an automated system that create unfair outcomes for particular groups, often arising from skewed training data, flawed features, or proxy variables.

Related: Training Data Bias, Fairness Metrics, Disparate Impact
Explainability

The degree to which the reasoning behind a model's output can be understood and communicated to stakeholders such as auditors, regulators, customers, and decision-makers.

Related: Black-Box Model, Model Documentation
Black-Box Model

A model whose internal logic is not readily interpretable by humans, so its behavior can only be assessed through inputs, outputs, and post-hoc explanation techniques.

Related: Explainability, Model Validation
Concept Drift

A change over time in the statistical relationship between model inputs and the target outcome, degrading model performance even when input distributions look stable.

Related: Data Drift, Model Monitoring, Model Risk
Data Drift

A shift in the distribution of input data compared with the data used to train or validate a model, which can undermine the reliability of its predictions.

Related: Concept Drift, Model Monitoring
Hallucination

A generated output that is fluent and confident but factually wrong or unsupported by source material, common in large language models.

Related: Generative AI Risk, Human Oversight
Generative AI Risk

Exposures specific to systems that create text, images, or other content, including fabricated facts, harmful content, intellectual property issues, and leakage of sensitive information.

Related: Hallucination, Prompt Injection
Prompt Injection

An attack in which crafted input causes a language model to ignore its intended instructions and follow the attacker's, potentially exposing data or triggering unauthorized actions.

Related: Generative AI Risk, Adversarial Testing
Model Inventory

A maintained register of an organization's models recording purpose, owner, risk rating, dependencies, and status, serving as the foundation for governance and oversight.

Related: Model Risk, Model Owner, Model Validation
Model Owner

The accountable individual or function responsible for a model's design, performance, documentation, and remediation of issues throughout its lifecycle.

Related: Model Inventory, Three Lines of Defense
Three Lines of Defense

A governance structure in which operational teams manage risk, an independent risk function provides oversight, and internal audit gives assurance.

Related: Model Owner, Independent Review
AI Governance Framework

A structured set of policies, roles, processes, and controls that directs how an organization develops, deploys, and supervises AI systems in line with its risk appetite.

Related: Risk Appetite, Model Inventory
Risk Appetite

The amount and type of risk an organization is willing to accept in pursuit of its objectives, expressed as statements or limits that guide AI decisions.

Related: AI Governance Framework, Risk Tolerance
Risk Tolerance

The acceptable variation around a risk appetite, often expressed as concrete thresholds or limits that trigger escalation when breached.

Related: Risk Appetite, Key Risk Indicator
NIST AI Risk Management Framework

A voluntary U.S. framework organizing AI risk work into govern, map, measure, and manage functions to help organizations build trustworthy AI systems.

Related: AI Governance Framework, Risk Assessment
ISO/IEC 42001

An international standard specifying requirements for an AI management system, covering governance, risk treatment, and continual improvement within an organization.

Related: AI Governance Framework, Independent Review
Risk Assessment

A structured process of identifying, analyzing, and evaluating risks by considering likelihood and impact to prioritize treatment and allocate resources.

Related: Risk Register, Inherent Risk
Risk Register

A living record of identified risks with owners, ratings, controls, and treatment plans, used to track and report risk status over time.

Related: Risk Assessment, Residual Risk
Inherent Risk

The level of risk that exists before any controls or mitigations are applied, providing a baseline for judging the value of controls.

Related: Residual Risk, Risk Assessment
Residual Risk

The risk remaining after existing controls and mitigations have been applied, which must be compared against risk tolerance.

Related: Inherent Risk, Risk Tolerance
Model Validation

Independent evaluation of whether a model is conceptually sound, performs as intended, and is appropriate for its use, typically before deployment and periodically thereafter.

Related: Independent Review, Model Risk
Independent Review

Assessment of a model or AI system performed by parties not responsible for building it, to reduce conflicts of interest and provide objective challenge.

Related: Model Validation, Three Lines of Defense
Adversarial Testing

Deliberate probing of a system with crafted or edge-case inputs to reveal weaknesses, unsafe behavior, or exploitable vulnerabilities before and after deployment.

Related: Red Teaming, Prompt Injection
Red Teaming

A structured exercise in which a team simulates attackers or adversaries to find failures, misuse paths, and safety gaps in an AI system.

Related: Adversarial Testing, Prompt Injection
Human Oversight

Arrangements ensuring people can monitor, intervene in, or override an AI system's outputs, especially for high-impact decisions.

Related: Human-in-the-Loop, Hallucination
Human-in-the-Loop

A control design in which a person reviews and approves an AI output before it takes effect or affects a customer or decision.

Related: Human Oversight, Automation Bias
Automation Bias

The tendency of people to over-trust automated recommendations and reduce their own scrutiny, weakening the effectiveness of human review controls.

Related: Human-in-the-Loop, Human Oversight
Defense in Depth

A control strategy layering multiple independent safeguards so that failure of one control does not leave the system unprotected.

Related: Risk Mitigation, Residual Risk
Risk Mitigation

Actions taken to reduce the likelihood or impact of a risk, such as redesigning a model, adding controls, restricting use, or transferring risk.

Related: Defense in Depth, Residual Risk
Model Monitoring

Ongoing tracking of a deployed model's performance, inputs, and outputs to detect degradation, drift, or unexpected behavior and trigger remediation.

Related: Concept Drift, Key Risk Indicator
Key Risk Indicator

A metric chosen to give early warning that risk exposure is rising, such as error rates, complaint volumes, or override frequencies, tied to escalation thresholds.

Related: Risk Tolerance, Model Monitoring
Fairness Metrics

Quantitative measures comparing model outcomes or error rates across groups, used to detect and track disparate treatment or impact.

Related: Algorithmic Bias, Disparate Impact
Disparate Impact

A situation where a neutral-seeming practice or model produces substantially different outcomes for a protected group, a concept central to fair-lending and employment scrutiny.

Related: Algorithmic Bias, Fairness Metrics
Model Documentation

Written records describing a model's purpose, data, assumptions, limitations, and validation results, supporting auditability and informed use.

Related: Explainability, Model Inventory
Audit Trail

A chronological record of system activity, inputs, outputs, and changes that allows reconstruction of decisions and supports investigation and regulatory review.
