About this tool
Team Scaling Cost Model
The Team Scaling Cost Model computes total growth cost from hiring, onboarding, and communication overhead with Brooks's Law context.
• Model true cost of doubling engineering team size
• Calculate onboarding cost for a hiring plan
• Quantify communication overhead growth at different team sizes
• Build case for keeping teams small rather than growing one large team

FAQ
What does this tool tell you?
The Team Scaling Cost Model computes total growth cost from hiring, onboarding, and communication overhead with Brooks's Law context.
What affects the result most?
Brooks's Law: adding engineers to late project makes it later — communication overhead O(n²). Communication links: n×(n-1)/2 — 5 engineers=10 links, 10 engineers=45 links. Onboarding cost: 3-6 months to full productivity × salary — real cost of hiring.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
