Translate business goals, user journeys, risk appetite and policy obligations into measurable quality dimensions, scenario coverage, scoring rubrics and acceptance criteria.
DataConsultant evaluates large language models, retrieval-augmented applications and AI agents against business requirements, representative user tasks and risk controls. The service combines test design, human judgement, automated measures and failure analysis to help product, data, technology, risk and procurement teams make informed release, remediation or vendor-selection decisions.
LLM quality assessment is a structured service for testing whether a large language model or generative AI application performs reliably for its intended use. It supports product owners, AI leaders, technology teams, risk functions and procurement teams by defining evaluation criteria, building representative test cases, measuring outputs, reviewing failures and documenting release thresholds. Deliverables commonly include a test plan, benchmark results, failure taxonomy, risk findings and remediation priorities. Results remain dependent on test coverage, evidence quality, model access and the continuing variability of generative systems.
The engagement can focus on a single model decision, a production application, a model comparison or an ongoing assurance programme.
Translate business goals, user journeys, risk appetite and policy obligations into measurable quality dimensions, scenario coverage, scoring rubrics and acceptance criteria.
Run representative, boundary, adversarial and regression tests using automated metrics and calibrated human review across model, prompt, retrieval and agent configurations.
Prioritise failure modes, control gaps and design changes; define retesting requirements; and provide a decision pack for release, vendor selection or remediation.
Apply consistent scenarios and scoring rules across models, versions, prompts or suppliers.
Move beyond average scores to understand where, why and for whom the system fails.
Connect acceptance criteria to use-case impact, user exposure and control requirements.
Create reusable test assets and release gates for future changes and production monitoring.
Generative AI can appear convincing even when an answer is unsupported, incomplete, inconsistent or unsafe. A structured assessment helps separate demonstration quality from dependable operational performance.
No agreed evidence shows whether the application is reliable enough for real users or high-impact decisions.
Outputs introduce claims that are not supported by source material or provide misleading references.
Teams compare demos, marketing claims or isolated prompts rather than controlled business scenarios.
Prompt, model, retrieval or tool updates improve one area while weakening another.
Risk, audit or procurement teams lack documented criteria, findings, ownership and review decisions.
Share the intended use case, current architecture and decision that the evidence must support.
Evaluate answer correctness, source coverage, citation faithfulness, access boundaries and abstention when evidence is missing.
Test policy adherence, completeness, tone, escalation, sensitive-data handling and consistency across realistic customer scenarios.
Assess extraction accuracy, summarisation fidelity, traceability and performance on long, complex or contradictory documents.
Review tool selection, permission boundaries, step completion, recovery, logging and human-approval points.
Compare candidates using the same task set, scoring rubric, operating constraints and risk thresholds.
Detect quality changes after model, prompt, retrieval, policy or orchestration updates.
Deliverables are adapted to the decision, system maturity and level of assurance required.

| KPI | What it indicates | Baseline needed | Limitation |
|---|---|---|---|
| Task success rate | Completion against the agreed rubric | Representative test set | Depends on scenario coverage and reviewer calibration |
| Grounded response rate | Use of valid supplied evidence | Traceable source set | Does not prove factual completeness beyond available sources |
| Critical failure rate | Frequency of severe safety or business failures | Severity definition | Rare events require sufficiently broad testing |
| Regression pass rate | Stability after system changes | Versioned benchmark suite | Cannot cover every future input |
| Human-review agreement | Consistency of judgement | Calibrated rubric and reviewers | Some subjectivity remains |
Pricing is prepared after initial discovery because evaluation depth depends on the decision, risk and evidence required.
Provide the intended use case, model environment and decision deadline for a practical commercial proposal.
Evaluation starts with the decision, users and operating consequences rather than a generic metric catalogue.
Quality, data, engineering, governance, safety, privacy and operational considerations can be assessed together.
Assumptions, evidence gaps, uncertain findings and residual risks are documented rather than hidden behind a single score.
Models, configurations and suppliers can be compared against the same defined requirements.
Test cases, rubrics, failure taxonomies and release gates can support future product changes.
Teams receive practical guidance for maintaining evaluation, interpreting results and governing changes.
Start with the business decision, system scope and evidence currently available.
Define approved datasets, minimisation, masking, retention, deletion, residency and access requirements for prompts, outputs and reference material.
Version models, prompts, configurations, datasets, rubrics and reviewer records so findings remain traceable and repeatable.
Review authentication, permissions, tool access, logging, secret handling and prompt-injection exposure within scope.
Record accountable owners, approval criteria, residual risk, escalation, review frequency and changes requiring reassessment.

Supply platform documentation, access, configuration details, incident information and technical remediation where contractually applicable.
Representative feedback is presented below to illustrate the delivery qualities organisations value in an LLM Quality Assessment Service engagement.
“The assessment gave us a clearer basis for deciding where the assistant could be used and where human review was still necessary. The team connected quality findings to actual user journeys, documented evidence gaps and converted the main failure patterns into a practical release and remediation plan.”
“Stakeholder workshops were well structured and helped product, legal, risk and engineering teams agree on what good performance meant. The scoring rubric and decision log reduced subjective debate, while revisions were handled carefully when new policy and customer-service scenarios were introduced.”
“We needed more than a model score. DataConsultant helped define ownership, acceptance thresholds, escalation routes and the evidence required for our governance forum. The final pack made residual risks visible and separated technical remediation from decisions that needed accountable business approval.”
“The model comparison used consistent prompts, retrieval conditions and reviewer guidance, which made the trade-offs easier to understand. The team did not overstate small score differences and explained where latency, operating cost, groundedness and failure severity should influence our architecture decision.”
“The regression suite and knowledge-transfer sessions were especially useful. Our engineers received clear examples of how to maintain test cases, calibrate reviewers and investigate failures after prompt or retrieval changes. The documentation was detailed enough to support ongoing release reviews without creating an impractical process.”
“Communication remained direct throughout the engagement, including when access limitations affected the original plan. Findings were traceable to test evidence, comments from our subject-matter reviewers were incorporated, and the final revisions clearly distinguished confirmed issues, assumptions and areas that required further operational monitoring.”
These answers explain typical scope, evidence needs, limitations, commercial factors and ongoing assurance options.
An LLM quality assessment is a structured evaluation of how reliably a large language model performs against defined business, technical, safety and governance requirements. It combines representative test cases, human review, automated measures, failure analysis and documented acceptance criteria.
Assessment is useful before procurement, before production release, after a model or prompt change, when adding retrieval or tools, when performance concerns emerge, and as part of ongoing assurance for high-impact or regulated use cases.
The scope can include task accuracy, relevance, groundedness, completeness, consistency, robustness, safety, bias, privacy leakage, instruction following, citation quality, latency, cost and escalation behaviour.
Yes. The assessment can cover retrieval quality, context sufficiency, citation faithfulness, tool selection, tool execution, workflow completion, memory behaviour, permission boundaries and recovery from failed steps.
Typical deliverables include an evaluation plan, test dataset, scoring rubric, benchmark results, failure taxonomy, risk register, model or configuration comparison, remediation priorities, acceptance criteria and an executive decision summary.
Testing uses domain-specific prompts, unanswerable questions, conflicting context, incomplete evidence and adversarial cases. Outputs are reviewed for unsupported claims, incorrect citations, invented facts and failure to acknowledge uncertainty.
No. An assessment provides evidence within an agreed scope and test period. It does not guarantee future behaviour, legal compliance, certification, security or regulatory approval, and it should be combined with appropriate operational controls and specialist review.
Useful inputs include intended use cases, user groups, policies, model and prompt configurations, retrieval sources, representative queries, known incidents, risk thresholds, architecture details, access controls and accountable reviewers.
Timing depends on the number of use cases and models, access to representative data, test-case complexity, languages, integrations, human-review needs and stakeholder approval cycles. A reliable duration is set after discovery.
Cost is influenced by scope breadth, model count, test volume, domain expertise, data preparation, red-team depth, languages, integrations, human evaluation, governance documentation and whether ongoing monitoring is included.
Yes. A controlled benchmark can compare candidate models, versions, prompts, retrieval configurations or vendors against the same scenarios, scoring rules, risk thresholds and operational constraints.
Yes. Ongoing support can include regression suites, release gates, production sampling, drift and incident review, scorecard reporting, test-set maintenance and periodic reassessment.
