No system dies in a single event — it decays through small, reasonable decisions: a quick import, a bypassed abstraction, a duplicated rule. Governance is the practice of keeping the structure aligned with the intent.
The best governance is not a committee. It is rules enforced automatically, plus a lightweight review process for the decisions that need judgment.
Enforce rules in CI
Turn your architecture constraints into tests that run on every pull request.
- Dependency rules: "domain layer must not import infra" (dependency-cruiser).
- Size and complexity budgets that fail the build.
- Architecture tests that verify package boundaries.
- Deprecation linters that flag removed APIs.
A rule enforced by the build does not require a meeting. It requires a pull request that satisfies it.
Lightweight review checkpoints
Reserve human governance for decisions that cross boundaries: adding a new module, a new integration, or a new dependency. A short architecture review on those changes is cheap insurance.
Make decay visible
Track architectural health like you track bugs: module coupling trends, test coverage at boundaries, and the count of "temporary" workarounds. Visibility turns decay from a surprise into a trend you can manage.
Architecture governance FAQ
Does governance slow development?
Bureaucratic governance does. Automated rules and targeted reviews add minutes, not days, while preventing the expensive rewrites that decay causes.
Who enforces architecture rules?
The build enforces mechanical rules. A senior engineer or architect reviews the few changes that cross documented boundaries.
