## What the story says

Ancestry uses Harness to run its CI/CD pipelines with centralized governance, replacing many separate Jenkins instances. This lets the architecture team apply standards and best practices, such as canary deployments, across all pipelines with a single change.

Summary written by usedby from the source page, in English. The figures are those of Harness and Ancestry, not ours.

> The increase in pipeline governance and consistent usage of best practices enabled by Harness also resulted in a 50% decrease in overall production outages and significantly reduced outages related to deployment issues.

- **3x**: “a 3x increase in deployment velocity”
- **97%**: “Ancestry’s centralized testing tool’s adoption rate rose to 97%”
- **350**: “onboard 350 systems in the first year”
- **85%**: “an 85% reduction in effort when compared to Jenkins”

> Once teams are using a Harness pipeline, it’s easy to add additional mandatory steps
