How to document AI output quality for compliance

What they're actually asking

The question sounds like "is it accurate." What the person needs is usually narrower and more procedural: can you show a defined standard, evidence that you measure against it, evidence you'd notice if it degraded, and a record of what you did when it did.

That's a process question, not a research question, and it's answerable. A single impressive accuracy figure is not — the immediate follow-up is "measured how, on what, by whom, and when," and a number without those is worth nothing to a reviewer.

Write down what good means, first

Everything else depends on this. Your criteria have to be specific enough that two people applying them independently agree, because a reviewer will reasonably ask whether the standard is real or post-hoc.

Say what's checked, in behavioral terms. Say what's disqualifying — the absolute conditions that fail an output regardless of everything else. And say what thresholds you hold: which rate on which criterion is acceptable, and why that number.

That last one gets skipped and it's the one a reviewer pushes on. The strongest justification is a human baseline: this is the rate a trained person achieves on the same set. It reframes the conversation from "is AI good enough" to "is this as good as what it replaced," which is both more answerable and more honest.

Keep humans in the record

Any documentation of quality that involves no human judgment is fragile, because the obvious question is who validated the automated scoring.

Have people rate a sample. Not everything — a defined sample on a schedule. Use more than one rater so you can show agreement between them, which is the evidence that the standard is real rather than one person's preference.

Record who they were and what qualifies them. "Two support team leads with three years in the domain" is meaningful; "the team" is not.

Make it a schedule, not an event

A one-time assessment documents a moment. A reviewer wants to know you'd catch a problem next quarter.

Define the cadence and hold it. Monthly or quarterly for most systems, plus a run on any material change — a new model, a prompt revision, a corpus update. Write the trigger conditions down, because "we run it when something changes" is weaker than a list of what counts as a change.

Then actually keep the runs. The value is in the series, not in any single result, and a record showing twelve consecutive quarters is a far stronger artifact than one very thorough report.

Keep the failures

This is counter-intuitive and it's the thing that most improves credibility.

A record showing only passing runs looks curated, and a reviewer will assume it is. A record showing a run that dipped, what you found, what you changed, and the subsequent run recovering is evidence that the process works — it detected something and produced a response.

Document incidents the same way. What happened, how you found out, what changed, what you added to the test set so it can't recur unnoticed. That last part is what turns an incident from a liability into evidence of a functioning control.

Version everything, and record what produced what

A reviewer will ask which version of the system produced a given output. You need to be able to answer.

Record the version of the prompt or flow, the model and its version, the corpus if retrieval is involved, and the rubric version used for scoring. Keep them linked to the run.

This matters for a specific reason people underestimate: a model provider can update a model beneath you. Without a record of what you called and when, you can't distinguish "our system changed" from "the model changed," and that distinction is exactly what an audit turns on.

Say what you don't cover

Every honest quality document has a boundary section, and including it makes the rest more credible rather than less.

Name what the evaluation set represents and what it doesn't. Name the failure modes you test for and the ones you don't. Name where a human reviews output and where nothing does. Name the residual risk you've accepted and who accepted it.

A reviewer who finds an unstated gap discounts your entire document. A reviewer who sees the gaps stated and bounded reads the rest as trustworthy. This is the single highest-return paragraph in the whole artifact.

Match the effort to the actual obligation

Regulatory requirements vary enormously by sector and jurisdiction, and this guide describes a general quality-documentation practice rather than compliance with any specific regime.

Find out what actually applies to you before building the artifact, and get someone qualified to tell you. Sector rules, procurement requirements from a large customer, and general obligations are three different things with three different bars.

The practice above is worth doing regardless, because it's the same work that makes the system better. But do not assume it satisfies a specific legal requirement without asking somebody who knows.
