Spreadsheet / Financial Model
Build a working spreadsheet-style model (budget, forecast, unit economics, pricing, or scenario calculator) with clearly separated inputs, calculations, and outputs. Scopes the model's purpose, drivers, and assumptions FIRST so the formulas have a contract, then builds the model with live formulas and labeled assumption cells, then verifies the math by hand-checking key outputs and a sanity scenario. Use this for a financial model, budget calculator, ROI/forecast spreadsheet, unit-economics model, or any input-driven calculator.
How it runs
| # | Step | Who runs it | What happens |
|---|---|---|---|
| 1 | Scope the model | Planner | lock the purpose, drivers, assumptions, and outputs |
| 2 | Build the model | Developer | implement the model with live formulas and labeled cells |
| 3 | Evaluate | Reviewer | Grade the deliverable against every acceptance criterion. All pass → finish; any fail → loop back and fix the gap. |
| 4 | Finish | Developer | All acceptance criteria met. Stamp a short summary and report DONE. |
