TL;DR: AI lifecycle governance keeps ownership, risk classification, and policy attached from ideation through decommissioning, and the article argues that model-only review breaks down once agents keep acting in production after launch, according to Collibra. The trust assumption collapses when systems accumulate risk after their first approval, not before it.
NHIMG editorial — based on content published by Collibra: AI lifecycle governance: Governing models and agents from ideation to decommissioning
Questions worth separating out
Q: How should security teams govern AI systems across their full lifecycle?
A: They should treat lifecycle governance as a continuous control model with a single record of ownership, risk, policy, and current access.
Q: Why do AI agents create more governance risk than static models?
A: AI agents keep acting after approval, which means their operational behaviour can drift from the intent captured during review.
Q: What breaks when decommissioning is treated as optional in AI governance?
A: Stale access, orphaned records, and unresolved audit history remain after the system should have been retired.
Practitioner guidance
- Create a single lifecycle record for every AI system Capture the owner, intended use, risk tier, and current access state in one system of record from intake through retirement, rather than stitching together separate review logs.
- Extend governance into runtime monitoring Require continuous visibility into what each agent or model can reach, which tools it calls, and whether its live behaviour still matches the approved use case.
- Make decommissioning a hard control point Revoke access, archive evidence, and close the inventory entry when an AI system is retired so stale permissions do not survive the business need.
What's in the full article
Collibra's full blog post covers the operational detail this post intentionally leaves for the source:
- The seven-stage lifecycle table with stage-by-stage controls for ideation, data sourcing, development, validation, deployment, operation, and decommissioning.
- The article's discussion of how an AI Command Center acts as a system of record for governance continuity.
- The operational differences between model review and agent monitoring in production.
- The retirement workflow details that make decommissioning auditable instead of symbolic.

Lifecycle governance fails when organisations treat approval as the end of control. That assumption was designed for systems whose risk profile is mostly fixed at release. It breaks when the actor continues to operate, accumulate scope, and touch live data after the first review. The implication is that governance has to be understood as a living control state, not a one-time gate.
A few things that frame the scale:
- 91% of former employee tokens remain active after offboarding, leaving organisations vulnerable to potential security breaches, according to The 2025 State of NHIs and Secrets in Cybersecurity.
- 62% of all secrets are duplicated and stored in multiple locations, causing unnecessary redundancy and increasing the risk of accidental exposure.
A question worth separating out:
Q: How does lifecycle governance support IAM and IGA programmes?
A: It extends familiar identity disciplines such as ownership, review, and offboarding into AI operations. That gives IAM and IGA teams a consistent way to govern non-human systems that evolve over time, instead of handling AI as a separate exception with weaker accountability.
