Evaluate AI Factuality Before Outputs Inform Business Decisions
DataConsultant evaluates factual claims, evidence use, source faithfulness, citation integrity and uncertainty handling in generative AI and retrieval-augmented systems. The service helps AI, product, data, technology, risk and business teams understand where outputs are dependable, where failure patterns remain, and what controls or remediation are needed before wider deployment or continued operation.
Why Factuality Evaluation Matters
Generative AI can produce fluent, persuasive outputs that are still incorrect, weakly evidenced or misleading. A factuality programme turns broad concerns about “hallucinations” into specific claims, evidence, severity and repeatable control decisions.
Unsupported claims
Plausible but incorrect statements can enter reports, customer responses or operational decisions.
Partial correctness
Some facts may be accurate while omitted conditions or context materially change the conclusion.
Citation defects
References may be missing, misaligned, invented, stale or unrelated to the claim they appear to support.
Conflicting sources
AI may blend incompatible source statements without explaining which evidence is current or authoritative.
Overconfident outputs
High-confidence wording can encourage users to accept uncertain information without appropriate verification.
Stale or weak sources
Outdated references, incomplete retrieval or low-quality content can produce factually weak answers.
Hidden reviewer gaps
Automated scores may miss domain nuance, material omissions or evidence quality issues that require expert review.
Inconsistent behaviour
Similar prompts, model versions or retrieval settings may produce materially different factual outcomes.
From Current State to Target State
Move from ad-hoc output checks to a structured, risk-based factuality assurance programme with repeatable evidence, named ownership and change-triggered re-testing.
Current State
- Ad-hoc spot checks
- Limited test coverage
- Opaque failure handling
- Inconsistent evaluation
- Unclear ownership
- Reactive issue resolution
Target State
- Structured, repeatable evaluation
- Representative test sets
- Traceable evidence and sources
- Risk-based assessment
- Defined release criteria
- Ongoing monitoring and assurance
Assess Your Highest-Risk AI Outputs
Identify factuality risks before unsupported or misleading content affects customers, employees or business decisions.
What Our Factuality Evaluation Service Covers
An end-to-end, risk-based approach can be scoped from evaluation design through remediation, regression testing and operating controls.

Align Factuality Tests With Business Risk
Translate customer, operational, regulatory and decision risks into proportionate evaluation coverage and acceptance criteria.
Governance, Risk and Control Model
Clear rules, thresholds, evidence and accountability help turn factuality findings into release and remediation decisions.
Severity Framework
Define impact categories, recurrence factors and escalation logic.
Benchmark Approval
Approve test sets, source collections and version controls.
Evidence Requirements
Set traceability, reviewer notes and source-quality expectations.
Escalation Thresholds
Define when findings need owner, risk or executive review.
Issue Ownership
Assign accountable owners and target actions for material findings.
Retest Evidence
Retain proof that remediation was evaluated against the right version.
Release Decision
Record go, conditional go, restriction, remediation or no-go criteria.
Change-Triggered Regression
Re-evaluate after model, prompt, retrieval, source or policy changes.
Error Prioritisation Matrix
Illustrative matrix only. Actual severity and recurrence bands should be defined against the business consequences of the evaluated system.
Prioritisation considers more than a score
- Business and user consequence
- Evidence weakness and detectability
- Frequency, exposure and recurrence
- Downstream decision or automation impact
- Control effectiveness and reviewer visibility
- Remediation complexity and re-test urgency
