DevOps is a set of practices that brings software development and IT operations together to deliver reliable changes faster.
Delivery is a team system
DevOps connects coding, testing, deployment, operations, and feedback. The goal is a dependable flow of small changes, not simply a collection of automation tools.
Measurement guides improvement
Lead time, deployment frequency, failure rate, and recovery time reveal where delivery is struggling. Collaboration and ownership are as important as pipelines.
