CFO AI Ledger

An independent finance-leadership publication that examines where AI changes planning, close, cash, control, disclosure, and capital decisions—and what evidence a CFO must require before relying on it.

Authority-to-use-case crosswalk

ISO/IEC 42001 and internal control and audit evidence

A decision-specific crosswalk between ISO/IEC 42001 and internal control and audit evidence for AI for CFOs, with authority class, evidence requirements, human ownership, and interpretation limits kept visible.

Direct answer

Assess whether an organization has a defined management system; verify scope rather than relying on a badge.

Start with the authority class

AI management systems

Before applying the record, determine whether it is binding law, regulator guidance, a technical or management standard, a professional code, an industry framework, or a voluntary risk resource. Preserve issuer, jurisdiction, version, status, effective date, intended audience, and the exact passage connected to the decision. Similar language does not make two authorities interchangeable.

Define the executive use case

AI can index control narratives, map evidence requests, and flag missing documentation. It cannot by itself establish control design, operating effectiveness, audit sufficiency, or management's conclusion.

The crosswalk should name the affected population, decision or action, source data, model or product, provider and customer roles, human judgment, possible harm, and the evidence another reviewer would need. Authority language should be connected to this operating record—not attached to a generic AI inventory entry.

Question-by-question application

1. Is the AI itself in scope for change and access controls?

Read this question through the scope of ISO/IEC 42001. Assess whether an organization has a defined management system; verify scope rather than relying on a badge. Record the exact source passage, the interpretation owner, the affected internal control and audit evidence step, and the evidence that would show the decision is operating as intended. If the authority does not answer the question directly, preserve that gap instead of filling it with a provider claim or an editorial assumption.

The ISO/IEC boundary matters here: The authority record does not certify a product, provider, program, or organization and does not determine buyer-specific applicability. For CFOs, the answer should state what changes in responsibility, information, review, approval, monitoring, or communication. It should also name what remains outside the authority's scope and which legal, risk, privacy, security, financial, employment, marketing, coaching, or technical specialist must confirm the conclusion.

2. Can evidence provenance survive export and retention?

Use-case questions

  1. Is the AI itself in scope for change and access controls?
  2. Can evidence provenance survive export and retention?
  3. Who resolves conflicts between a summary and the underlying record?

Evidence needs

  • current official authority source
  • configured workflow evidence
  • representative normal and exception results
  • named interpretation and decision owners

Risks of a superficial mapping

  • false assurance
  • incomplete populations
  • privileged or confidential evidence leakage
  • a framework name used as a substitute for scoped applicability
  • provider documentation treated as proof of organizational conformity
  • a control described in design but not tested in operation
  • a source revision that does not trigger reassessment

A useful mapping is deliberately modest. It identifies the decision, operating obligation, responsible person, evidence, unresolved question, and next review trigger. It does not turn a publication summary into legal advice or a product feature into an assurance conclusion.

Review record to retain

  1. Capture the current official source and exact relevant passage.
  2. Record who interpreted it and which professional owner must confirm applicability.
  3. Map the interpretation to the actual internal control and audit evidence workflow and affected population.
  4. Identify preventive, detective, corrective, and governance controls.
  5. Test at least one normal case, difficult exception, override, and source change.
  6. Preserve the conclusion, dissent, residual risk, evidence, and date for re-review.

AI-management-system lens

For internal control and audit evidence, confirm the organization and activities inside the management-system scope, the AI policy and objectives, assigned responsibilities, risk and impact processes, controlled lifecycle records, supplier controls, monitoring, internal review, corrective action, and evidence of continual improvement. A certificate should be read with its scope and issuer.

Separate the provider's management system from the buyer's configured use. The buyer still needs evidence for its purpose, data, people, integrations, human decisions, local controls, incidents, outcomes, and changes; provider certification does not transfer automatically to that operating workflow.

Interpretation boundary

The authority record does not certify a product, provider, program, or organization and does not determine buyer-specific applicability.

The publication supports research and executive decision preparation. It does not provide legal, financial, accounting, employment, clinical, cybersecurity, investment, procurement, or implementation advice.
