Case Study: Entur boosts deployment frequency and cuts rollback time with Harness

Entur Improves Deployment Frequency from Twice a Week to 14 Times a Day, Rollback Time from Two Hours to Five Minutes

Entur, the Norwegian public transport data and travel platform, needed a more scalable way to deliver software as its development teams grew from 12 to 20. Using manual production deployments, complex CircleCI pipelines, and an in-house feature flag system, the team faced slow deployment cycles, high maintenance overhead, a 20% change failure rate, and rollback times of up to two hours. They turned to Harness CD and Feature Flags to improve control in production and support faster growth.

Harness implemented a self-service continuous delivery and feature management approach for Entur, with streamlined UI-based deployments, rolling releases, canary support, RBAC, and rapid rollbacks. As a result, Entur increased deployment frequency from twice per week to more than 14 times per day, reduced change failure rate from 20% to 5%, and cut rollback time from two hours to five minutes.
