A useful AI product helps someone complete a specific task. Before release, the product manager needs evidence that it improves that task without creating unacceptable errors, cost or review work. This guide uses an evaluation contract to record the task, test cases, release thresholds, owner and fallback in one place.
NIST’s Generative AI Profile frames risk management across the lifecycle through the AI RMF functions: govern, map, measure and manage. NIST AI RMF The framework is voluntary and does not prescribe one launch process. That is useful: each enterprise must turn broad risk principles into the concrete release evidence its workflow needs.
The evaluation contract
An evaluation contract is a short document that product, engineering, operations and risk can all challenge. It should answer:
| Element | What must be decided before rollout |
|---|---|
| Workflow | Which user task is assisted, and which remains human-owned? |
| Output | What does the system produce: draft, classification, extraction, recommendation or action? |
| Harm boundary | What should never happen, even if the model is confident? |
| Test set | Which real, de-identified or synthetic cases represent normal, edge and adversarial use? |
| Threshold | What measured result is sufficient for a limited release? |
| Operations | Who reviews failures, handles escalation and can disable the system? |
| Change control | What changes require re-evaluation: model, prompt, retrieval corpus, tool, policy or workflow? |
This is not a model scorecard alone. A high answer-quality score does not make a support assistant safe if it exposes protected data, or a triage model useful if it sends the wrong queue work to the wrong team.
Work from a task-level metric
“The model seems good” is not a release criterion. Start with an observable business task and measure the result the workflow owner cares about.
For document extraction, that could be field-level accuracy and the rate at which an operator must correct a proposed value. For an internal policy assistant, it could be grounded-answer accuracy, citation coverage, unsupported-answer rate and time to resolution. For incident triage, it could be correct routing, missed critical cases and time to human acknowledgement.
NIST’s Generative AI Evaluation Program is a useful reminder that evaluation is a measurement discipline, not a one-time product demonstration. An enterprise team does not need to reproduce a research benchmark. It does need a maintained set of cases that exposes the failure modes its own users will encounter.
Measure the current workflow too. If an operator resolves a request in four minutes using search, compare the assistant’s total task time, including checking sources and correcting mistakes. Track cost per completed task, not just cost per model call. A cheap draft that takes six minutes to repair is a poor result. The timings here are illustrative.
Keep a held-out evaluation set that prompt authors do not tune against. Include the languages, document quality and exception types users actually encounter. Record reviewer disagreements and sample size alongside averages; a small set with no observed failures cannot establish that rare failures never happen.
Score the disposition, evidence and action separately
Answer quality, evidence quality and permission compliance answer different questions. Use a rubric that makes each failure visible before deciding whether to release. The following is a proposed evaluation design, not a NIST scoring standard.
| Check | Pass evidence | Failure that cannot be averaged away |
|---|---|---|
| Disposition | Expected answer, clarification, abstention or escalation | Answering a case that requires a hold |
| Evidence | Approved source and version support each material claim | A valid-looking citation that does not support the answer |
| Access | Only permitted tenant, account and document scope retrieved | Cross-tenant disclosure |
| Action | Allowed tool and arguments; authority valid at execution | Prohibited mutation or expired authority |
| Recovery | Unknown result is investigated under the provider contract | Duplicate payment or invented completion |
Report the count and severity of failures in each dimension. A mean answer score must not hide a prohibited tool call. Set the release rule before the run, freeze the candidate versions and record reviewer disagreements. Keep held-out cases separate from prompt tuning.
A synthetic test set specifies behavior to exercise. Expected answers are labels, not measured model results. Record actual outputs and reviewer decisions separately when an evaluation is run. For retrieval-specific cases, continue to RAG evaluation for merchant support.
Worked example: an internal policy assistant
Illustrative example, not a reported implementation. A payments operations team wants an assistant that answers questions from approved operating procedures. It must not make account changes, approve exceptions or interpret policy beyond its published source.
In this example, the first evaluation set contains 120 de-identified questions: routine questions, ambiguous wording, obsolete-policy traps, questions where the source has no answer, and requests that try to obtain confidential details. Each case has an expected disposition: answer with a citation, ask for clarification, say the information is unavailable, or escalate.
The release threshold might be: all answers to high-risk questions escalate or refuse; every answer shown to the user links to an approved source; and a trained reviewer judges a defined proportion of routine answers as correct. The exact numerical threshold is a business decision based on harm and workload, not a universal AI benchmark.
In shadow mode, the assistant generates answers but agents continue using the existing search process. Reviewers compare recommendations with actual resolutions. If a policy document changes, the team re-runs the affected cases before the new source is available to the assistant. If the retrieval service cannot establish a source, the product falls back to search or escalation rather than generating a plausible answer.
The release decision rests on those observed outcomes, including the cases where the assistant correctly asks for help.
Use gates that match the risk
One approval path for every AI use case either blocks useful low-risk work or lets consequential systems slip through with weak evidence. Risk-tier the portfolio by what the AI can affect.
- Drafting and summarisation: no direct customer or regulated decision. Focus on data handling, user disclosure and basic quality checks.
- Internal workflow assistance: a bad result can delay, misroute or confuse work. Add representative evaluation, queue-owner review and incident handling.
- Customer-facing assistance: outputs affect customer communication or service. Add accessibility, language, complaint and escalation checks.
- Decision support: outputs influence fraud, credit, compliance, pricing or eligibility. Add stricter evidence, independent challenge and clear human accountability.
- Action-taking agents: the system invokes tools, changes records, initiates payments or creates external obligations. Add least-privilege tools, transaction boundaries, approval controls and a tested kill switch.
The last tier should not inherit the release process of a writing assistant. OWASP’s agentic guidance calls out goal hijack, tool misuse and identity or privilege abuse as distinct risks. OWASP, Agentic Applications Top 10 Product scope, tool permission and runtime controls must therefore be evaluated together.
Roll out in stages, not by confidence alone
A disciplined sequence is usually more valuable than trying to forecast every failure upfront.
Offline evaluation: test the release candidate against the agreed set. Keep the cases, labels, reviewer notes and version identifiers.
Shadow mode: run on live-shaped traffic without making the AI output operational. Compare its output with the established workflow.
Limited release: restrict users, regions, task types or tool permissions. Make feedback and escalation easy.
Monitored expansion: expand only after the owner reviews quality, harms, cost, latency, adoption and operational load.
Rollback and learning: disable the route when a control fails, preserve evidence, identify whether the cause was a model, prompt, data source, tool or process, then re-evaluate before restoring access.
Versioning is essential. A change to a model, system prompt, retrieval corpus, tool schema or policy can change the product’s behaviour. Treat such changes as release candidates, not invisible configuration updates.
Microsoft Foundry’s evaluation guidance distinguishes simulated conversations before deployment from monitoring quality using existing conversations in production. Microsoft Learn, evaluate generative AI The specific tooling is optional; the operating lesson is not. Evaluate the known task before release, then keep evaluating representative production work after release with access and privacy controls.
Delegation, revocation and monitoring
An agent that can call a tool needs an authority contract in addition to an answer-quality evaluation. Record the allowed tools, permitted data, transaction or value boundary, user confirmation point, accountable owner and how access is revoked. A tool permission that changes the product’s possible actions is a material release change, even when the prompt stays identical.
Illustrative example, not a reported implementation. An operations assistant may draft a case summary and create a low-priority internal ticket, but cannot change an account, submit a payment or override a review queue. Its owner can disable the tool route immediately. If the team later allows it to create a customer-visible case, it tests that narrowed action, its consent copy, failure path and revocation control before enabling it.
Monitoring should make failures traceable without casually retaining sensitive data. Microsoft’s agent tracing guidance shows that traces can include prompts, outputs and tool inputs or outputs. Microsoft Learn, trace an agent Decide what is collected, who can view it, what is redacted and how long it is retained before enabling observability. Vendor capabilities are examples, not universal enterprise requirements.
Use the enterprise AI operating model for portfolio ownership and handoffs. This guide stays focused on the release evidence for one workflow.
The trade-off: coverage versus control
Teams often want a general assistant because it promises broad adoption. Broad coverage also expands the possible data, policies, tools and exceptions the system must understand. A narrow assistant may initially feel less ambitious, but it produces a smaller test surface and clearer ownership.
The same applies to autonomy. Requiring review can slow a workflow; allowing direct action can create irreversible harm. The right choice depends on the consequence of error, the quality of the available evidence and the user’s ability to recover. Product managers should make that trade-off explicit, rather than treating human review as a temporary inconvenience to remove later.
Launch checklist
- Is the workflow and non-goal clear enough that a reviewer can identify scope creep?
- Does the test set include routine, ambiguous, missing-information and adversarial cases?
- Are success and harm metrics tied to the actual task?
- Is each output traceable to a model/version, data source and human action where applicable?
- Does the workflow owner have time and authority to review failures?
- Are tool permissions and data access no broader than the task requires?
- Is shadow-mode evidence reviewed before a limited release?
- Can the team disable the AI path without disabling the underlying service?
Enterprise AI is a product and operating-model change. An evaluation contract makes the change discussable before customers, operations teams or auditors have to discover its boundary through a failure.
FAQ
What is an AI evaluation contract? It is the agreed evidence for a rollout: task, boundaries, test set, thresholds, monitoring, accountable owner and rollback path.
Is a single accuracy score enough? No. Measure the task outcome and the failures that matter: unsupported answers, misroutes, unsafe tool calls, privacy exposure, escalation quality and recovery.
When should a team re-evaluate? Before material changes to the model, prompt, retrieval data, tool permissions, policy or workflow, and after a significant production failure.
