Software Engineering basics - DORA Metrics & DevOps Performance Indicators

DORA Metrics are a standardized set of key performance indicators for software delivery and operational performance. Developed through extensive industry research, these metrics provide objective insights into how effectively teams deliver and operate software systems.

The four core DORA metrics are Deployment Frequency, Lead Time for Changes, Change Failure Rate, and Mean Time to Recovery (MTTR). Together, they balance speed and stability, ensuring that rapid delivery does not compromise reliability.

Deployment Frequency measures how often software is released, reflecting automation and confidence. Lead Time captures the time from code commit to production, indicating pipeline efficiency. Change Failure Rate assesses quality by tracking failed releases. MTTR evaluates operational resilience by measuring recovery speed.

High-performing teams demonstrate both fast delivery and high stability, disproving the myth that speed and quality are mutually exclusive. These metrics emphasize system performance rather than individual productivity, discouraging unhealthy competition or gaming.

DORA metrics are widely used for benchmarking, continuous improvement, and transformation initiatives. They guide investment decisions in tooling, process improvements, and cultural practices that enhance overall DevOps maturity.
