Model Integrity Review (MIR) is a fixed-scope, management-led, document-based review of an analytical model and its
supporting documentation. MIR focuses on structural clarity, internal consistency,
assumption traceability, and documentation sufficiency for
management oversight, audit, or decision use.
MIR exists to answer a narrow but critical question:
Can leadership clearly understand, explain, and stand behind this model as it is currently documented?
The review focuses on explainability under reasonable questioning, not on technical correctness or analytical performance.
MIR complements existing validation or governance programs by focusing on
clarity and defensibility of the model as documented,
not statistical testing or regulatory compliance.
Scope boundaries (read first)
- MIR does not build, modify, execute, or optimize models.
- MIR does not validate model correctness or performance.
- MIR does not certify, approve, or endorse models or outcomes.
- MIR does not provide regulatory sign-off or legal opinions.
- MIR does not support litigation, testimony, or media strategy.
If validation, certification, or redesign is required, MIR will say so directly.
Engagement steps
1) Fit and materials check
You send a short note describing the model’s decision context, who needs to stand behind it,
and what documentation exists today.
The fit check is designed to confirm that a document-based review can answer the leadership question above.
2) Scope framing and fixed fee
MIR confirms review boundaries and a fixed fee before work begins.
Scope is stated explicitly to avoid implied validation or endorsement.
3) Review (document-first)
MIR reviews the materials as provided, focusing on whether leadership can explain what the model assumes,
produces, and limits under reasonable questioning.
- Structural clarity (what is here, and how it is organized)
- Internal consistency (definitions and claims align across artifacts)
- Assumption traceability (assumptions can be tied to outputs as documented)
- Documentation sufficiency (a decision owner can cite the basis for claims)
4) Deliverable
A short written review memorandum describing scope, materials reviewed, observed strengths, and documentation or structural risks.
Advisory only — not an endorsement, certification, or validation.
5) Optional clarification
Limited clarification questions only; no redesign, no execution, and no validation follow-on.
