For Project Finance & PPP / Infrastructure
Keep long-tenor infrastructure models navigable, source-bound, and change-aware.
Bind the source inputs, map the model structure, and isolate the changes that move debt-case outputs.
Workflow stack
- Bind Source / Bind Vector for source integrity
- Trace Precedents / Dependents / Flow Diagram for navigation
- Worksheet Map + Risk Heatmap for structure and review triage
- Compare + MCI for version changes
Handoff
A source-bound input set, active-sheet map/export workbook, heatmap review lens, and comparison/MCI delta packet.
Source bindings detect drift from a captured source snapshot. They do not prove the source itself is authoritative or commercially correct.
Workflow proof
Each promise maps to commands, context, result, artifact, and limit.
No demo placeholder. These panels describe the actual command stack and the output a reviewer or model owner can expect to see.
Pin the source assumptions that drive the case
Open related docs →SituationTariffs, inflation curves, EPC costs, debt terms, or operating assumptions need traceable source context.
Commands usedModelXcel ProProofBind SourceKeytipBSModelXcel ProProofBind VectorKeytipBVModelXcel ProProofVerify WorkbookKeytipVWWhat the user sees- Source kind, target, notes, SHA-256 snapshot, vector range, and fresh/broken verdicts after verify.
- Proof ledger records for source bindings and any later drift.
Output artifactWorkbook proof ledger plus bound source/vector records that can be included in a certificate snapshot.
Caveat / limitBinding detects whether the captured value changed. It does not validate that the tariff, macro source, or contract term is correct.
Navigate a large workbook without losing the thread
Open related docs →SituationA 30-tab model has cross-sheet logic, external links, named ranges, and hand-edited formulas.
Commands usedModelXcel ProFormula ToolsPrecedentsKeytipTPModelXcel ProFormula ToolsDependentsKeytipTDModelXcel ProFormula ToolsFlow DiagramKeytipFDShortcutCtrl+Shift+WWhat the user sees- Precedent/dependent trees, formula flow modes, cell references, named ranges, external-reference nodes, and navigation back to the grid.
- A diagram that distinguishes formula structure from direct cell inputs.
Output artifactTrace/diagram output for review notes and a list of links or formulas needing follow-up.
Caveat / limitExternal workbook references are surfaced as references; the tools do not chase closed external workbooks as if they were open dependency graphs.
Turn workbook structure into a review map
Open related docs →SituationBefore lender or authority review, the team needs to know where inconsistencies, hardcodes, and complex formulas concentrate.
Commands usedModelXcel ProMapWorksheet MapKeytipWMModelXcel ProMapRisk HeatmapKeytipRHShortcutCtrl+Shift+RWhat the user sees- A diagnostics tree, same-workbook <source>_Map sheet, map legend, and Risk/Structure/Audit heatmap modes.
- Heatmap category counts and a heuristic health score in the legend panel.
Output artifactWorksheet Maps - <timestamp>.xlsx export for selected map sheets, plus heatmap-guided review notes.
Caveat / limitWorksheet Map analyzes an active worksheet and generated map sheets; Risk Heatmap is a heuristic visualization, not proof of correctness.
Explain the version delta before it becomes a meeting
Open related docs →SituationA bank case, sponsor case, or authority-return version changes DSCR, LLCR, PLCR, IRR, NPV, or another key metric.
Commands usedModelXcel ProCompareCompare to Previous VersionModelXcel ProCompareCompare WorkbooksKeytipCOCompare ResultsExplain Output ChangeMCIWhat the user sees- Version picker, grouped workbook deltas, aligned-sheet detection, and output attribution into ranked drivers.
- Dependency paths from changed inputs to the selected project metric.
Output artifactComparison result and MCI explanation packet for the selected output movement.
Caveat / limitMCI explains selected output movement from the compared files; it is not a general assurance opinion on the model.
Outputs
Artifacts this workflow can hand off.
The artifact matters because the claim matters. A sidecar, certificate snapshot, map workbook, comparison packet, and signed replay envelope all prove different things.
