avoiding the cost of delays (CoDs) associated with recalls, rework, and fixing defects
CALMR approach to DevOps - ANS-- Culture: Establish and culture of shared
responsibility for development, deployment and operations
- Automation: Automate the Continuous Delivery Pipeline
- Lean flow: Keep batch size small, limit WIP, and provide extreme visibility
- Measurement: Measure the flow through the pipeline. Implement application telemetry
- Recovery: Architect and enable low-risk releases. Establish fast recovery, fast
