AI Governance Program Milestone Framework
Define structured governance milestones — evaluated at intervals across a deployment's lifecycle — that must be completed before an AI system advances to the next stage, treating governance readiness as a project dependency rather than a parallel or post-hoc activity.
Objective
Ensure AI deployments are not advanced past defined lifecycle checkpoints without documented governance evidence, by establishing a milestone framework that connects governance completion to deployment progress.
Maturity Levels
Initial
Governance activities occur independently of deployment timelines. AI systems may go live before governance reviews are complete, with governance treated as a post-deployment task.
Developing
Governance teams are engaged during major AI projects but milestone criteria are informal. Deployment is not blocked by incomplete governance activities in practice.
Defined
A governance milestone framework defines checkpoints at defined intervals (e.g., 30-day, 60-day, 90-day from intake) with specific governance evidence requirements at each checkpoint. Deployment advancement is blocked pending milestone completion for systems above a defined risk tier.
Managed
Milestone completion is tracked in the project management or GRC system. Milestone exceptions (advancement without full completion) are documented with risk acceptance and approver sign-off. Milestone findings feed into the continuous assurance function (MGV-004).
Optimizing
Milestone requirements are calibrated by deployment type and risk tier: high-risk systems face more milestones with higher evidence standards; low-risk systems use a streamlined track. Milestone cycle times are measured and used to improve the governance process efficiency.
Evidence Requirements
What an auditor or assessor would expect to see for this control.
- —Governance milestone framework document defining checkpoints, required evidence at each checkpoint, and gate criteria by risk tier.
- —Milestone tracking records for all active AI deployments, showing completion status and date for each milestone.
- —Exception log documenting any deployments that advanced past a milestone gate before completion, with risk acceptance sign-off.
- —Evidence that deployment advancement was blocked or delayed pending milestone completion for at least one instance in the past 12 months.
Implementation Notes
Governance as a project dependency
The most common reason AI governance fails to keep pace with deployments is structural: governance is positioned as a parallel workstream that runs alongside development rather than as a dependency that deployment must wait for. Parallel workstreams get deprioritized when schedules slip. Dependencies do not.
A governance milestone framework converts governance activities into explicit project dependencies by attaching required evidence to defined delivery gates. The project cannot advance to the next phase without milestone evidence. This is the same model used in regulated software development (SOC 2, FedRAMP, medical device software) and it is effective for the same reason: it makes governance completion a prerequisite for the outcome the project team wants.
A 90-day framework for new deployments
Day 0 — Intake complete: Required: Completed intake form (MGV-002) with risk tier assigned, business owner named, data classification documented, vendor assessment status confirmed. Gate: Deployment may proceed to experimental stage only.
Day 30 — Governance foundations: Required: Vendor due diligence complete (if external model, PRC-001); DPIA initiated (if personal data); AI inventory entry created; staged release policy reviewed and deployment staged appropriately (MGV-001). Gate: Deployment may continue in experimental stage; limited production access may be requested.
Day 60 — Pre-production clearance: Required: DPIA complete (if required); red-team or adversarial testing complete (SAF-005); monitoring configuration in place (MON-001, MON-002); incident response coverage confirmed (IRC-001, IRC-002); human oversight structure documented (HOC-001, HOC-002). Gate: Deployment may advance to limited production stage.
Day 90 — Full production approval: Required: Post-deployment validation complete (CHM-004); governance committee sign-off; AI model registry entry complete with all required fields; compliance mapping complete (CMP-001 for in-scope regulations). Gate: Deployment may advance to production-approved status.
Adapting the framework by risk tier
| Risk tier | Framework | Milestone count |
|---|---|---|
| Low | Abbreviated: Day 0 and Day 30 only | 2 |
| Medium | Standard: Day 0, Day 30, Day 60 | 3 |
| High | Full: Day 0, Day 30, Day 60, Day 90 | 4 |
| Critical | Extended: All milestones + additional review at Day 120 | 5 |
Connecting milestones to the continuous assurance function
The milestone framework applies to new deployments. Once a system reaches production-approved status, ongoing governance is handled by the continuous assurance function (MGV-004) and change management (CHM). The milestone framework and continuous assurance function are two phases of the same governance lifecycle: milestone framework governs entry; continuous assurance governs steady state.
Example Implementation
AI Governance Milestone Tracker — [System Name]
Risk tier: High | Framework: Full (4 milestones) | Intake date: 2026-04-01
| Milestone | Due date | Status | Evidence reference | Gate decision |
|---|---|---|---|---|
| Day 0 — Intake complete | 2026-04-01 | Complete | Intake record AI-2026-031 | Experimental stage approved |
| Day 30 — Governance foundations | 2026-05-01 | Complete | PRC-001 assessment 2026-0412; DPIA initiated (ref DPA-2026-09); AI inventory entry AIS-147 | Limited production request submitted |
| Day 60 — Pre-production clearance | 2026-06-01 | In progress | Red-team complete (SAF-2026-19); monitoring configured (see MON ticket 2026-088); HOC-001 classification: High risk; HOC-002 approval gate: required for all outputs above 85% confidence threshold | PENDING — DPIA not yet signed off; gate blocked |
| Day 90 — Full production approval | 2026-07-01 | Not started | — | Blocked pending Day 60 |
Current status: Day 60 gate blocked — DPIA sign-off outstanding. Estimated unblock: 2026-06-10. Risk acceptance: Not applicable (no exception requested; team is resolving blocker). Escalation: AI Governance Committee notified of delay 2026-06-05.
