Verify models before high-stakes decisions
Shared pattern: The model looks finished. A decision is approaching. Confidence is thinner than the deadline.
Independent verification is designed for that moment — regardless of whether the model was built by hand, inherited from a template, assisted by a spreadsheet copilot, or generated by an automated workflow.
Decision contexts where verification helps
The same discipline applies across settings — pick the rows that match your week:
| Context | What is at stake | Verification focus |
|---|---|---|
| Lender or credit meeting | Covenant headroom, debt service, collateral narrative | Covenants, cash flows, statement ties |
| Client or sponsor presentation | Credibility of outputs you are endorsing | Material drivers, scenario case, obvious defects |
| Investment committee | Capital allocation, returns, downside | Scenario provenance, key sensitivities |
| Board or credit committee | Formal approval on recorded minutes | Statement integrity, version frozen vs presented |
| Transaction close or signing | Locked numbers vs last iteration | Version comparison, last-minute edits |
| Internal sign-off | Partner or manager reliance | Assumption documentation, structural consistency |
You do not need a different product for each — you need a repeatable pass before the meeting that matters.
The independence question
Ask explicitly:
Could the same system that helped build this model also confirm it is correct — without a separate check?
If the answer is yes, you have speed — not independent assurance.
Kalc is designed as the separate check: it does not build models; it verifies them and returns severity-ranked findings with cell-level evidence.
What a useful verification pass covers
The same four questions as the product — designed to help you see:
- Does the model hold together? Formula consistency across the grid; assumptions documented and traceable.
- Does the finance hold together? Whether statements in the workbook appear to tie.
- What does it actually say? Whether the saved scenario case is identifiable.
- What evidence does the analysis leave? What changed since the last pass, when comparing versions. An exportable record — not a sign-off.
Findings identify and suggest. You decide what to fix and what to escalate.
Synergies with consulting and internal review
Verification before the meeting complements formal review:
| Before external review | Fix clear defects; arrive with a findings summary |
|---|---|
| During iteration | Re-run after material edits |
| After review | Confirm remediations landed; catch drift |
| Between full engagements | Maintain baseline hygiene when a full review is not yet booked |
Productivity: fewer rounds on issues you could have caught early.
Before the meeting: you know your starting point before someone else reads the file cold.
When software is enough — and when to escalate
| Use verification passes | Escalate to human review |
|---|---|
| Iteration between meetings | Sign-off for credit/regulatory filing |
| Preparing a pack for your reviewer | Dispute or litigation support |
| Sanity check before a client call | Novel structure outside your team's experience |
Optional: verify in an automated build loop
Teams using agents or scripts to populate models can call the same independent check via API/MCP: build → verify → remediate from findings → re-verify. The agent builds; the checker stays separate.
