Meet The Social Side of Your Architecture
summary
Argues that invisible organizational structure causes defects and delays and gives concrete ways to measure it: compute fractal figures from git by aggregating file commits into architectural components (fractal value 0–1) and spot components where 40–70% of commits touch multiple layers. Shows real microservice data: some services are 20–40k LOC with high team fragmentation, others 1–2k LOC still tightly coupled by change coupling, producing a “change-caplan” bottleneck. Recommends team-sized services (3–4 people), package-by-component, careful database boundaries, and tools like Codemap and CodeScene.
