1. Users

Identity and access lifecycle controls: onboarding, offboarding, MFA, and privileged role boundaries. Evidence to review: export user and role assignments, review inactive or guest accounts, compare MFA/Conditional Access coverage, and sample recent joiner-mover-leaver tickets.

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

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

Controls around user identity determine who can access sensitive systems, data, and admin features, making identity hygiene the first line of defense and operational control. Review evidence for MFA enforcement, least privilege, RBAC, break-glass accounts, stale identities, SSO/SAML, sign-in logs, privileged access groups.

Business impact

Poor user hygiene drives unauthorized access risk, orphaned accounts, and longer incident investigations when credentials are misused or forgotten. Exposure increases when exceptions lack owners, alerts are not reviewed, or recovery evidence is missing.

What Users are

Users are the microsoft 365 licensing 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 users, the relevant evidence usually includes export user and role assignments, review inactive or guest accounts, compare MFA/Conditional Access coverage, and sample recent joiner-mover-leaver tickets. Review the related MFA enforcement, least privilege, RBAC, break-glass accounts, stale identities, SSO/SAML, sign-in logs, privileged access groups, 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 Entra admin center, Active Directory Users and Computers, sign-in logs, audit logs, access reviews, PowerShell exports.

2. Plans

Review plans 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.

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

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

Plans 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 plans 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 Plans are

Plans are 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 plans, 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.

3. Security add-ons

Review security add-ons 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.

Are exceptions, ownership, monitoring records, and response evidence for security add-ons documented well enough for audit or incident response?

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

Security add-ons 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 security add-ons 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 Security add-ons are

Security add-ons are 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 security add-ons, 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.

4. Annual cost

Review annual cost 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 annual cost identify the control owner, approved baseline, evidence location, and most recent validation date?

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

Annual cost 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 annual cost 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 Annual cost is

Annual cost is the microsoft 365 licensing 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 annual cost, 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.

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.

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

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

Documentation 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.
