Detailed analysis
A proper variance review compares actuals to budget, forecast and prior period, then assigns owners and decisions. Variance should separate timing, volume, price, one-time items and execution gaps.
Practical example
Marketing spend is 40% above budget. Finance splits variance into planned campaign pull-forward, agency overspend and lower CAC efficiency. Decision: freeze non-performing channels and revise next-month forecast.
Evidence and control checklist
| Area | What to check | Evidence to save |
|---|---|---|
| Definition and owner | Define budget vs actual variance, owner, source system and review frequency. | Metric dictionary, owner matrix and version log. |
| Source data | Books, bank, CRM, payroll, billing, contracts or statutory filings used. | Source extracts and reconciliation sheet. |
| Computation logic | Formula, assumptions, exclusions and period consistency. | Working paper and CFO sign-off. |
| Decision impact | How the output affects pricing, hiring, spend, funding or compliance. | Management note and action tracker. |
| Diligence evidence | Whether an investor/auditor can verify the number independently. | Indexed folder with contracts, reports and approvals. |
