Lessonly by Seismic transitioned from Jenkins to Harness CI, granting over 30 developers access and ownership of the build process, which led to enhanced self-sufficiency and a better developer experience without needing intervention from the Site Reliability Engineering (SRE) team. Previously acquired by Seismic in 2021, Lessonly is a training and enablement solution used by over four million learners at more than 1,200 companies. The change to Harness CI Enterprise provided a unified CI/CD solution, allowing developers to follow artifacts from creation to deployment across environments, thus easing the development process with improved logging and visibility. This transition enabled developers to independently handle build failures, a task that was previously difficult with Jenkins due to limited access. The SRE team praised Harness for its user-friendly interface and features like the YAML editor and Visual Pipeline Builders, which facilitated easy onboarding and setup, empowering developers to manage the entire application delivery process autonomously.
