AI evaluation, governance & quality

Know What Works.
Know Where It Stops.

Evaluate AI answer quality, permissions, costs and failure cases, and define practical ownership, review and change-control processes.

THE BUSINESS CONTEXT

Start with
What Matters.

A convincing demonstration does not show how an AI application behaves across the full range of business tasks. Teams need representative evidence, clear responsibilities and a way to assess changes before extending the tool’s use.

We help turn business expectations into evaluation cases and operating rules. The work can support a new pilot or assess an existing assistant, with a scope tied to the decisions the business is preparing to make.

YOUR FIRST ENGAGEMENT

A Useful
Starting Point.

Focused Pilot

Assess one assistant using representative business questions, permission tests and an operating-cost review.

Discuss This Pilot

What We Need from You

Access to the evaluated application, representative tasks, expected results and responsible reviewers.

What We Can Measure

  • Grounded-answer rate
  • Failure-case coverage
  • Unauthorised access attempts blocked
  • Cost per successful task

Measures are agreed for your project. Results depend on the data, workflow and evaluation; they are not guaranteed improvements.

WHAT WE DO

The Detail Behind
the Capability.

01

Define Measurable Acceptance Criteria

Collect ordinary tasks, difficult examples and requests the tool should decline. Agree how correctness is judged and which errors matter most. Include a current-process baseline where possible. Keep the evaluation set separate from examples used to configure or tune the system.

02

Test Behaviour and Boundaries

Check factual grounding, source quality, permission separation and response to misleading instructions in retrieved content. Test unavailable tools, incomplete input and unauthorised actions. Automated scoring can assist, but representative human review remains essential for nuanced business outputs.

03

Establish Operating Ownership

Define who approves source content, model changes and expanded tool access. Document retention settings, review queues, incident routes and user feedback. Maintain a practical record of intended use and known limitations. Compliance obligations are identified with the customer’s qualified advisers rather than presumed satisfied by a checklist.

04

Monitor Changes and Cost

Record quality, latency and cost per completed task over time. Compare provider or prompt changes against the same evaluation cases before release. Maintain rollback options and scheduled reviews. Governance should make the tool easier to operate and improve, with responsibilities the team can actually sustain.

A DEFINED ENGAGEMENT

Know What
You’re Building.

Your proposal defines the exact scope, responsibilities, milestones, and exclusions. Depending on the engagement, the work can include:

  • Use-case and risk register
  • Representative evaluation dataset
  • Quality and permissions assessment
  • Operating roles and review policy
  • Change-control and monitoring plan
  • Prioritised remediation report

QUESTIONS, ANSWERED

A Few Useful Answers.

Is this a compliance certification?

No. The work provides technical and operational evidence. Formal certification, legal opinions and sector-specific approvals require the relevant qualified providers.

Can you assess a tool another provider built?

Yes, subject to suitable access and an agreed assessment scope. Some tests may be limited by the available interfaces and records.

Can the tests eliminate all hallucinations?

No. Evaluation reveals behaviour on the tested cases and helps improve controls. Monitoring, clear limits and human review are still needed in production.
