1. Revenue impact

Review revenue impact design, evidence location, control ownership, and recurring validation records. Evidence to review: collect invoices, tenant license assignments, Azure cost exports, project backlog, utilization metrics, and business impact assumptions.

Do the records for revenue impact identify the control owner, approved baseline, evidence location, and most recent validation date?

Review guidance, technical context, and business impact
Why it matters

Revenue impact must be traceable to an approved configuration, named owner, and dated validation record. Without that evidence, teams cannot prove the control is configured as intended or determine whether exceptions are still justified. Review evidence for license utilization, reserved capacity, consumption forecast, run-rate variance, TCO, labor load, downtime model, migration dependency.

Business impact

Weak revenue impact controls can leave stale access, unmonitored changes, unsupported assets, or untested recovery paths in production. The result is longer triage time, weaker audit evidence, and higher remediation cost. It can increase remediation cost and delay recovery.

What Revenue impact is

Revenue impact is the downtime cost calculator control area that defines expected configuration, ownership, supporting evidence, and review cadence. A reviewer should be able to confirm the current state from system exports, admin-console settings, monitoring records, tickets, and maintained documentation. For revenue impact, the relevant evidence usually includes collect invoices, tenant license assignments, Azure cost exports, project backlog, utilization metrics, and business impact assumptions. Review the related license utilization, reserved capacity, consumption forecast, run-rate variance, TCO, labor load, downtime model, migration dependency, then confirm which systems or users are affected, which logs prove the control is operating, and how exceptions are approved, tracked, and revisited. Common review sources include Microsoft 365 billing, Azure Cost Management, finance reports, PSA/ticketing reports, capacity dashboards, spreadsheet model.

2. Staff time

Review staff time design, evidence location, control ownership, and recurring validation records. Evidence to review: current invoices, asset counts, support tickets, downtime history, revenue or productivity assumptions, and growth forecasts.

Can the team prove that staff time matches the intended configuration and was reviewed after material changes?

Review guidance, technical context, and business impact
Why it matters

Staff time must be traceable to an approved configuration, named owner, and dated validation record. Without that evidence, teams cannot prove the control is configured as intended or determine whether exceptions are still justified. Review evidence for assumption register, cost model, utilization baseline, sensitivity analysis, business-impact inputs.

Business impact

Weak staff time controls can leave stale access, unmonitored changes, unsupported assets, or untested recovery paths in production. The result is longer triage time, weaker audit evidence, and higher remediation cost. Risk increases when ownership, evidence, or exceptions are not documented.

What Staff time is

Staff time is the operating area where policy, configuration, monitoring, and support records need to agree with the actual environment. A reviewer should be able to confirm the current state from system exports, admin-console settings, monitoring records, tickets, and maintained documentation. For staff time, the relevant evidence usually includes current invoices, asset counts, support tickets, downtime history, revenue or productivity assumptions, and growth forecasts. Review the related assumption register, cost model, utilization baseline, sensitivity analysis, business-impact inputs, then confirm which systems or users are affected, which logs prove the control is operating, and how exceptions are approved, tracked, and revisited. Common review sources include billing portals, asset inventory, ticketing reports, finance exports, capacity dashboards.

3. SLA

Review sla design, evidence location, control ownership, and recurring validation records. Evidence to review: sample recent tickets and changes, verify approval and rollback records, compare documentation against production, and confirm named owners.

Are exceptions, ownership, monitoring records, and response evidence for sla documented well enough for audit or incident response?

Review guidance, technical context, and business impact
Why it matters

SLA must be traceable to an approved configuration, named owner, and dated validation record. Without that evidence, teams cannot prove the control is configured as intended or determine whether exceptions are still justified. Review evidence for SLA, RACI, change advisory review, rollback plan, runbook accuracy, configuration management, evidence repository, operational KPIs.

Business impact

Weak sla controls can leave stale access, unmonitored changes, unsupported assets, or untested recovery paths in production. The result is longer triage time, weaker audit evidence, and higher remediation cost. Risk increases when ownership, evidence, or exceptions are not documented.

What SLA is

SLA is the technical and administrative control set used to prove this part of the environment is configured, maintained, and reviewed. A reviewer should be able to confirm the current state from system exports, admin-console settings, monitoring records, tickets, and maintained documentation. For sla, the relevant evidence usually includes sample recent tickets and changes, verify approval and rollback records, compare documentation against production, and confirm named owners. Review the related SLA, RACI, change advisory review, rollback plan, runbook accuracy, configuration management, evidence repository, operational KPIs, then confirm which systems or users are affected, which logs prove the control is operating, and how exceptions are approved, tracked, and revisited. Common review sources include ticketing system, documentation portal, change calendar, asset inventory, monitoring alerts, configuration exports.

4. Recovery

Recovery sequencing, priority assignment, and business continuity readiness. Evidence to review: review job success history, protected workload scope, immutable-copy status, last restore test, retention settings, and recovery dependency mapping.

Do the records for recovery identify the control owner, approved baseline, evidence location, and most recent validation date?

Review guidance, technical context, and business impact
Why it matters

Recovery must be traceable to an approved configuration, named owner, and dated validation record. Without that evidence, teams cannot prove the control is configured as intended or determine whether exceptions are still justified. Review evidence for RTO, RPO, 3-2-1 backup, immutable storage, air gap, restore verification, retention policy, recovery runbook, ransomware isolation.

Business impact

Weak recovery controls can leave stale access, unmonitored changes, unsupported assets, or untested recovery paths in production. The result is longer triage time, weaker audit evidence, and higher remediation cost. It often becomes visible during audits, renewals, or outside reviews.

What Recovery is

Recovery is the downtime cost calculator control area that defines expected configuration, ownership, supporting evidence, and review cadence. A reviewer should be able to confirm the current state from system exports, admin-console settings, monitoring records, tickets, and maintained documentation. For recovery, the relevant evidence usually includes review job success history, protected workload scope, immutable-copy status, last restore test, retention settings, and recovery dependency mapping. Review the related RTO, RPO, 3-2-1 backup, immutable storage, air gap, restore verification, retention policy, recovery runbook, ransomware isolation, then confirm which systems or users are affected, which logs prove the control is operating, and how exceptions are approved, tracked, and revisited. Common review sources include backup console, restore-test logs, storage reports, DR runbooks, cloud backup policy, ticketing evidence.

5. Documentation

Operational runbooks, evidence repositories, and procedure accuracy. Evidence to review: sample recent tickets and changes, verify approval and rollback records, compare documentation against production, and confirm named owners.
