Best Practices
- Automate Everything - Reduce manual toil
- Version Control All - Code, configs, infrastructure
- Shift Left - Test and secure early
- Measure What Matters - Focus on DORA metrics
- Embrace Failure - Learn from incidents
- Continuous Improvement - Iterate and optimize
- Collaboration - Break down silos
- Documentation - Runbooks and playbooks
