Multiple teams + shared platform = DevOps governance matters.
Standards: branching strategy, naming conventions, deployment workflow, code review process, test coverage thresholds, rollback procedures.
Tooling: standardise on one DevOps platform (DevOps Center, Gearset, Copado). Don't let teams pick differently — incompatibilities later.
Governance bodies: DevOps Council with team leads. Sets standards, reviews violations, evolves practices.
Metrics: deploy frequency, time-to-deploy, change failure rate, mean time to recovery (the DORA metrics). Track per team; benchmark.
Training: every engineer onboards through standard DevOps practices.
Architect role: define standards, enforce via reviews, evolve as platform changes.
