How companies ship code to production

(explained in 2 mins or less):

1 Plan

↳ Define change & acceptance criteria.

↳ Plan the rollout & risks early.

2 Code

↳ Write code & add tests.

↳ Each untested change is risky.

↳ Review & merge into the main branch.

3 Build

↳ Compile code & create an immutable artifact.

↳ Tag & store in artifact repository.

4 Test

↳ Run tests in stages, unit to e2e.

↳ Promote build only if all checks pass.

5 Deploy

↳ Release build to production with a gradual rollout.

↳ Monitor & roll back if needed.
