Why it works

The case study is specific about the before-state: builds queued for up to an hour and wasted 2-5 minutes per build installing tools. The quantitative section grounds the story with real operational numbers such as 1,100 builds per day and 10,000 minutes of daily build time. The interview format lets the engineer explain the mechanism in enough detail that another team could replicate the self-hosted agent approach.

Steal this

The 'quantitative and CI/CD metrics' section presents raw operational numbers as a standalone block, giving readers an instant scale check before the narrative digs into how results were achieved.
