Practical next steps for adoption

1. Start small: apply Clean Architecture to a new feature or service to validate the approach.
2. Establish shared standards: choose one resource as the team reference and run focused code reviews.
3. Use modern tooling: combine a clear architecture with linters, test suites, and targeted refactoring.
4. Measure outcomes: track lead time, bug rates, and deployment frequency to quantify improvements.
