Governance Hierarchy

What to check: Design management groups around platform responsibility and workload boundaries.

Why it matters: Hierarchy is the backbone of consistent guardrails.

Management Groups

What to check: Assign baselines at management group scope and keep inheritance easy to explain.

Why it matters: Low-level assignments are hard to audit.

Azure Policy

What to check: Use initiatives, remediation tasks, exemptions, and deny controls deliberately.

Why it matters: Policy should prevent drift and report meaningful exceptions.

RBAC

What to check: Review privileged access, custom roles, inherited assignments, service principals, and guest users.

Why it matters: RBAC errors can create broad control-plane risk.

Common failure pattern: Owner is used as a convenience role.

Example finding: Owner is used as a convenience role.

Suggested remediation direction: Apply least privilege and time-bound elevation.

Evidence to collect: capture the Azure objects, scopes, assignments, resource identifiers, and timestamps that prove the condition exists. Good evidence should let another reviewer understand the result without reopening the Azure portal and repeating the same investigation.

How to review it: separate isolated exceptions from repeated patterns. One exception may be acceptable when it has an owner, expiry, and rationale; a repeated pattern usually indicates a platform or operating model issue that belongs in the report.

How to report it: write the finding in business-readable language, then attach the technical evidence. The reader should understand the risk, the affected scope, and the recommended direction before they reach the detailed resource list.

Automation note: automate the evidence collection and consistency checks where possible, but keep human review for scope decisions, materiality, accepted exceptions, and remediation sequencing.

Tagging

What to check: Define required tags for ownership, environment, cost centre, and workload.

Why it matters: Tags support cost allocation and operational accountability.

Common failure pattern: Resources are untagged or use inconsistent tag names.

Example finding: Resources are untagged or use inconsistent tag names.

Suggested remediation direction: Enforce mandatory tags and remediate existing resources.

Evidence to collect: capture the Azure objects, scopes, assignments, resource identifiers, and timestamps that prove the condition exists. Good evidence should let another reviewer understand the result without reopening the Azure portal and repeating the same investigation.

How to review it: separate isolated exceptions from repeated patterns. One exception may be acceptable when it has an owner, expiry, and rationale; a repeated pattern usually indicates a platform or operating model issue that belongs in the report.

How to report it: write the finding in business-readable language, then attach the technical evidence. The reader should understand the risk, the affected scope, and the recommended direction before they reach the detailed resource list.

Automation note: automate the evidence collection and consistency checks where possible, but keep human review for scope decisions, materiality, accepted exceptions, and remediation sequencing.

Cost Management

What to check: Review budgets, orphaned resources, SKU choices, reservations, and cost allocation.

Why it matters: Cost governance is part of architecture quality.

Common failure pattern: Unused resources remain after workload changes.

Example finding: Unused resources remain after workload changes.

Suggested remediation direction: Remove waste and assign budgets at useful scopes.

Evidence to collect: capture the Azure objects, scopes, assignments, resource identifiers, and timestamps that prove the condition exists. Good evidence should let another reviewer understand the result without reopening the Azure portal and repeating the same investigation.

How to review it: separate isolated exceptions from repeated patterns. One exception may be acceptable when it has an owner, expiry, and rationale; a repeated pattern usually indicates a platform or operating model issue that belongs in the report.

How to report it: write the finding in business-readable language, then attach the technical evidence. The reader should understand the risk, the affected scope, and the recommended direction before they reach the detailed resource list.

Automation note: automate the evidence collection and consistency checks where possible, but keep human review for scope decisions, materiality, accepted exceptions, and remediation sequencing.

Monitoring

What to check: Check activity logs, diagnostics, alert routing, and compliance reporting.

Why it matters: Governance needs evidence that controls remain effective.

Common failure pattern: Policy compliance is not reviewed regularly.

Example finding: Policy compliance is not reviewed regularly.

Suggested remediation direction: Create recurring review and remediation cycles.

Evidence to collect: capture the Azure objects, scopes, assignments, resource identifiers, and timestamps that prove the condition exists. Good evidence should let another reviewer understand the result without reopening the Azure portal and repeating the same investigation.

How to review it: separate isolated exceptions from repeated patterns. One exception may be acceptable when it has an owner, expiry, and rationale; a repeated pattern usually indicates a platform or operating model issue that belongs in the report.

How to report it: write the finding in business-readable language, then attach the technical evidence. The reader should understand the risk, the affected scope, and the recommended direction before they reach the detailed resource list.

Automation note: automate the evidence collection and consistency checks where possible, but keep human review for scope decisions, materiality, accepted exceptions, and remediation sequencing.

Common Mistakes

What to check: Avoid unmanaged exceptions, unclear ownership, duplicated controls, and report outputs that do not explain impact.

Why it matters: Governance fails when nobody can explain how it works.

Common failure pattern: Exceptions are granted but never reviewed.

Example finding: Exceptions are granted but never reviewed.

Suggested remediation direction: Track exceptions with owner, expiry, and rationale.
