DevOps Culture and Delivery Practices Questions

The principles and engineering culture behind modern software delivery: what DevOps means as a shared-ownership way of working and how to ease development and operations friction, adopting DevOps, infrastructure-as-code and GitOps practices across teams, the software development lifecycle and its methodology trade-offs (waterfall, agile, trunk-based development and branching agreements), engineering velocity and how it is measured without perverse incentives, development standards and how they are rolled out, enforced, excepted and justified with a business case, code review policy, turnaround expectations and handling bypasses, governance of shared delivery assets and changes to production automation, and the role of a platform team in enabling faster, safer delivery. Focuses on why teams work this way and how to drive adoption, not on how to build the machinery. Pipeline and build mechanics, deployment and rollback techniques, infrastructure tooling, reliability practice, and incident handling are covered elsewhere.
