DORA
DevOps Research and Assessment, an organization focused on studying the effectiveness of DevOps practices. Its published research reports provide quantitative evidence for the business value of CI/CD adoption.
Core Facts
Key metrics for effectiveness measurement include the four DORA metrics: deployment frequency, change lead time, change failure rate, and recovery time.
A McKinsey 2023 report noted that AI-assisted programming can shorten the software development cycle by approximately 20%–45%.
The DORA metrics framework, proposed by Google's DevOps research team, includes multiple dimensions such as deployment frequency, change lead time, and change failure rate.
Timeline (last 90 days)
The core metrics for measuring CI/CD maturity include deployment frequency, change lead time, change failure rate, and time to restore service; this framework has been tracked and validated over the long term by the DevOps research organization DORA.
DORA defines change failure rate as the proportion of deployments that require immediate intervention after release (such as a hotfix or rollback), and splitting it by author type requires only a PR label or the bot author's name.
The DORA metrics (DevOps Research and Assessment) were distilled by a Google research team based on large-scale industry surveys.
DORA research found that high-performing teams do not face a trade-off between speed and stability—they achieve both faster delivery and lower failure rates simultaneously.
DORA defines four core metrics for measuring software delivery performance: deployment frequency, lead time for changes, change failure rate, and mean time to restore service.
DORA (DevOps Research and Assessment) research has long shown that change failure rate and mean time to recovery are key metrics for measuring software delivery performance.
Value Stream Mapping originated in lean manufacturing and was later introduced into software delivery, with the core insight that the overall throughput of a system is determined by its slowest stage
Commonly used engineering productivity quantification metrics in the industry include the four DORA key metrics and the SPACE framework.
