There is a common lifecycle in startups:
- The Garage Phase (1-5 devs): Velocity is infinite. No process, no tests, just code. Everyone knows everything.
- The Early Stage (5-20 devs): Friction starts. "Who touched this file?" "Why did the build break?"
- The Scaling Phase (20-50+ devs): Velocity grinds to a halt. Communication overhead explodes.
Scaling isn't just "hiring more people." It's rewriting your operating system.
The Dunbar Number of Code
As you grow, you hit limits on how much context one person can hold. You can no longer rely on "tribal knowledge." If it isn't written down, it doesn't exist.
1. Standardize Patterns
In a small team, individual artistic expression in code is fine. In a large team, it's chaos. You need standardized linters, standardized folder structures, and standardized architectural patterns. "Boring" code is scalable code.
2. Async Communication
You can't have 50 people in a standup. You need to shift to writing. RFCs (Request for Comments), Design Docs, and Decision Logs become critical. They allow decisions to be made asynchronously and provide a history for new hires.
3. Metrics as a Compass
When you are small, you know who is struggling. When you are large, people can hide. High performers can burn out silently.
This is where tools like Velocinator become management infrastructure. You need high-level aggregates to see team health. Are the "Payments Team" cycle times slipping? Is the "Onboarding Squad" bogged down in rework?
Don't Hire to Fix Velocity
A common mistake: "We are moving too slow, hire 10 more engineers!" Brooks' Law states: "Adding manpower to a late software project makes it later."
New hires consume capacity (onboarding, mentoring) before they create it. If your processes are broken at 20 people, they will be disastrous at 40. Fix the pipeline, fix the tests, and fix the culture before you pour more people into the mix.
