/ THE SHORT ANSWER
Build an evaluation set from real workflow cases and score the system at the level of the business decision. Include normal, rare, ambiguous, missing, conflicting, restricted, adversarial, and harmful cases. Measure task success, evidence use, critical errors, refusal, escalation, latency, cost, and human review burden. Keep a versioned release gate and run the set whenever prompts, models, tools, sources, or policies change.
- 01Evaluate the end-to-end task and decision consequence.
- 02Include failures and non-answer cases, not only happy paths.
- 03Tie every release to a versioned threshold and review decision.
/ dotSuper point of view
An LLM evaluation is a maintained decision instrument. A one-time accuracy number cannot govern a system whose inputs, model, knowledge, and workflow continue to change.
What the evidence says
OpenAI’s evaluation guidance recommends defining objectives, collecting datasets, establishing metrics, comparing runs, and continuously evaluating as systems change.
NIST’s AI RMF places measurement inside a broader governance and risk-management process, connecting metrics to context and risk response.
A practical decision framework
The following framework is dotSuper’s operating synthesis of the cited guidance. It is designed to make the decision inspectable, not to imitate a platform ranking formula, certification checklist, or legal test.
- Dataset: representative cases, labels, evidence, owner, provenance, and risk class.
- Metrics: success, groundedness, critical error, escalation, latency, cost, and review time.
- Gate: thresholds by risk, mandatory failure checks, reviewer, and release decision.
- Monitoring: production sampling, drift, complaints, overrides, incidents, and regression runs.
| Step | Decision to record |
|---|---|
| 01 | Dataset: representative cases, labels, evidence, owner, provenance, and risk class. |
| 02 | Metrics: success, groundedness, critical error, escalation, latency, cost, and review time. |
| 03 | Gate: thresholds by risk, mandatory failure checks, reviewer, and release decision. |
| 04 | Monitoring: production sampling, drift, complaints, overrides, incidents, and regression runs. |
How to put it into practice
Start with 50–100 meaningful cases rather than thousands of synthetic prompts. Over-sample high-consequence and historically difficult cases, then add production failures as they appear.
Separate automatic metrics, model graders, and human judgment. Calibrate graders against expert review and never let an aggregate score hide a critical failure category.
- Name the accountable owner and the decision this work must enable.
- Record the current evidence, assumptions, exclusions, and next review trigger.
- Measure a useful outcome rather than treating publication or deployment as success.
What this page cannot conclude
- 01Evaluation sets can become stale or overfit to the current system.
- 02Model-based grading introduces its own uncertainty and requires calibration.
- 03Publication, technical eligibility, or good practice cannot guarantee ranking, referral traffic, citation, adoption, or a business outcome.
