Does this system hold in real conditions?
Post-Deployment Assurance: six-dimension check on whether a deployed AI system holds. Usage, stability, exceptions, output quality, control integrity, governance. Version 0, 2026.
Deployment is not the end of the engagement. An AI system faces operational reality only after it ships: uneven usage patterns, edge cases the validation set did not cover, drift in input distribution, control degradation, documentation decay. Post-Deployment Assurance assesses whether the system still does what it was signed off to do, and whether the controls installed at deployment still function.
Each dimension is rated 1 to 5 against the baseline set at deployment.
Actual adoption compared to intended adoption: who uses the system, how often, for what tasks.
Key checks
Uptime, error rates, latency profile, and input or output drift over time.
Key checks
How edge cases are caught, how human overrides are used, whether both are logged and learned from.
Key checks
Whether output quality remains within specification over time, with continuous monitoring in place.
Key checks
Whether the controls installed at deployment still function, and whether documentation matches current system state.
Key checks
Whether ownership persists, review cadence is respected, and incidents produce operational learning.
Key checks
Three conditions trigger automatic 'Not holding' classification, regardless of composite score.
No active monitoring of output quality
Not holding
A system without quality monitoring is operating blind.
System owner unnamed or unavailable
Not holding
An orphan system has no governance.
Documentation over 6 months out of date
Not holding
Outdated documentation breaks incident response and audit.
Post-Deployment Assurance produces five deliverables, suitable as a one-off review or as a quarterly retainer cadence.
Per-dimension scores against deployment baseline
Drift indicators (usage, stability, quality, controls)
Control integrity findings with severity
Continue / remediate / retire recommendation
Next review cadence proposal
One to two weeks for a one-off review. Quarterly cadence recommended for systems in production longer than six months. Annual for stable systems under active governance.
Post-Deployment Assurance produces a private operational review. It is not a certification of continued conformity, not a substitute for regulator-required periodic review, and not a SOC 2 Type II audit. It is the TRARDI discipline for verifying that a system still holds, at a cadence the client chooses.
We will walk you through how the review would apply to a specific deployed system and where the likely drift sits. No pitch.
