FAQPage Schema
How do I build a business case with ROI and sensitivity analysis for a new project?▼

Build an explicit investment thesis by forcing ROI assumptions, scenario analysis, sensitivity testing, and opportunity-cost accounting to validate budget requests, new market entries, and project prioritization.

What is ROI-driven investment planning and when do I need it?▼

ROI-driven investment planning quantifies expected returns, required capital, and breakeven points. You need it for budget requests, new market entries, and project prioritization where runway and opportunity costs matter.

How does sensitivity analysis work for evaluating investment thesis assumptions?▼

Sensitivity analysis simulates changes in your ROI assumptions to assess worst-case outcomes and evaluate risk. It ensures your investment thesis remains robust under varying financial projection scenarios.

Can I use this approach for project prioritization and opportunity-cost evaluation?▼

Yes, you can use this approach for project prioritization by comparing alternatives and documenting where resources could be better spent, ensuring explicit opportunity-cost accounting across your capital allocation decisions.

What is the best way to document explicit assumptions for a capital allocation proposal?▼

The best way to document explicit assumptions is to structure your capital allocation proposal around a defined ROI calculation, opportunity-cost accounting, and defined OKRs to justify the required investment.
