The CFO wants to see what happens if revenue drops 20%, if you hire 5 more engineers, or if you cut marketing by half. Building each scenario in Excel takes hours and comparing them side-by-side is a nightmare of copy-pasted tabs.

Who it's for: FP&A analysts modeling budget scenarios for leadership review, CFOs preparing budget options for board presentations, startup founders modeling runway under different growth assumptions, department heads building budget proposals with multiple options, finance managers stress-testing budgets against downside scenarios

Example

"Model 3 budget scenarios for next year" → Side-by-side comparison: conservative (flat growth, no hires), base (15% growth, 3 hires), and aggressive (30% growth, 8 hires) — with P&L impact, cash runway, sensitivity analysis on key variables, and executive recommendation

What This Does

Takes your current budget data and constraints, then generates side-by-side scenario comparisons with narrative implications, trade-off analysis, and clear recommendations. Turns "what if" questions into actionable executive-ready analysis.

Step 2: Gather Budget Data

Prepare: current budget breakdown, revenue targets, constraints, and scenarios leadership wants explored.

Step 3: Start Using It

claude

Say: "Model 3 budget scenarios: flat budget, 10% cut, and 15% growth. Show trade-offs for each."


Scenario Output

Component Purpose
Comparison Table Side-by-side numbers across scenarios
Narrative Impact Business implications in plain language
Trade-off Analysis What you gain/lose in each scenario
Sensitivity Testing What happens if assumptions change
Recommendation Clear pick with rationale
Executive Summary One-page decision-ready brief

Tips

  • Lead with narrative, not numbers: Executives grasp business implications before spreadsheet details
  • Make consequences explicit: "10% cut = lose 2 engineers = 3-month delay on product launch"
  • Find the breaking point: Where do cuts go from manageable to catastrophic?
  • Prepare reversibility context: Which cuts can be restored in weeks vs. months?

Commands

"Model 3 budget scenarios from this data"
"What's the impact of a 15% cut on headcount and delivery?"
"Generate an executive summary comparing all scenarios"
"Sensitivity test: what if revenue comes in 10% below forecast?"

Troubleshooting

Scenarios too similar Say: "Make scenarios more differentiated — conservative, moderate, aggressive"

Missing context Add: "Our top priority is launching the enterprise product by Q3"

Too many numbers, not enough insight Specify: "Lead with business narrative, numbers in supporting tables"
