Key Takeaways

The auto-deploy enablement on December 12, 2023 resulted in 15.3x more reliable deployments and 57.3% faster deployments. This transformation moved the team from manual, error-prone deployments to automated, reliable, and fast continuous deployment.

The introduction of feature environments in September 2023 was a mandatory step to move safely to continuous deployment, providing isolated testing environments that enabled confident automated deployments without production risks.

Additionally, DevOps best practices adoption stabilized the data pipelines failure rate on production, reducing failures by approximately 50-60% compared to pre-automation periods.
