DevOps is often presented as something that requires dedicated engineers, a tooling budget and a cultural transformation programme. For a team of fifteen building one or two products, that framing is unhelpful.

Four practices deliver most of the benefit, and a small team can put all four in place within a couple of weeks. None of them require hiring anyone.

The payback is measured in hours recovered every week and incidents that never reach a customer.

Automated deployment. One command or one merge puts code into production. The value is not only the time saved but the elimination of the step someone forgets at eleven at night.

Automated testing on every change. It does not need exhaustive coverage to be worth having. Tests covering the paths that would embarrass you catch most of what matters.

Monitoring and alerting. You should learn that something is broken from a monitor, not from a customer. This single practice changes the character of a support week.

Reproducible environments. Development, staging and production configured the same way, so works on my machine stops being a diagnosis.
