You do not need to become a finance person. You do need to stop treating the business as weather. This chapter gives engineers a working model of how companies fund work, how cost actually lands, and why a technically inferior option is sometimes the correct one.
We walk through unit economics at a depth that respects your intelligence, the difference between a capital and an operating decision, and how to talk about risk without turning every conversation into a disaster novel. Strategy, in this telling, is a set of bets with kill criteria — not a slogan on a slide.
The goal is modest and rare: you can sit with a GM or a CFO and be a partner, not a translator who needs a chaperone.
Lessons
- Every technical decision is a financial decision wearing overalls.
- Scope is a business lever. Treat it like one.
- You cannot be strategic if you cannot describe how the company gets paid.
Questions
- How does your team make or save money this year?
- What would you cut if your budget dropped 20% on Monday?
- Which ‘must-have’ in your roadmap has never been near a customer?
The P&L of a team
- Sketch your team’s cost (people, vendors, infra) on one page.
- Sketch the value it protects or creates, even if the number is a range.
- Identify one piece of work that cannot survive that comparison.
