AI implementation

Evaluating AI systems beyond the demo

A useful evaluation does not ask which model wins in isolation. It asks which system performs the work reliably inside its actual operating constraints.

Start with the decision

Define the decision this evaluation must support before selecting metrics. A production evaluation usually decides whether to advance, revise or stop a proposed implementation—not whether one model is universally better than another.

Working rule

Every measure should change a real implementation decision. If it cannot, it is observation rather than evidence.

Use three evidence planes

01

Implemented

Quality, latency, integration behaviour and failure recovery in the intended environment.

02

Adopted

Task completion, user trust, correction effort and the usability of fallback paths.

03

Governed

Traceability, policy adherence, accountable ownership and the evidence needed for review.

Build the scorecard

Keep thresholds explicit. Compare the system against the existing workflow and the production constraint, not against a demonstration baseline.

Measure	Threshold	Evidence
Task quality	Meets review rubric	Blind expert review
Latency	Within workflow tolerance	p50 / p95 trace
Recovery	Known failure path	Scenario test

Apply the guide

Run a representative pilot

Use real task distributions, edge cases and operators before the production decision.
