Growth Without Gridlock

Adding more engineers to a chaotic system does not increase velocity; it decreases it due to communication overhead (Brooks's Law). Scaling from 10 to 100 engineers requires fundamental shifts in organizational design.

Inflection Points

  • 1-10 Engineers: Everyone knows everything. Single monolithic codebase.
  • 10-30 Engineers: Need for specialized roles. Introduction of formal QA and initial DevOps. The monolith begins to creak.
  • 30-100 Engineers: Conway's Law takes effect. Need to split into cross-functional domains (e.g., "Squads"). Platform engineering becomes necessary.
