How good is our delivery pipeline?

Questions CTOs ask

What does a mature CI/CD pipeline look like?

A mature CI/CD pipeline includes automated builds triggered on every commit, a comprehensive test suite (unit, integration, and end-to-end) that runs in under 15 minutes, automated security scanning (SAST, dependency checking), infrastructure-as-code for environment provisioning, progressive deployment strategies (canary or blue-green), automated rollback on failure detection, and production observability that closes the feedback loop. Elite teams deploy multiple times per day with change failure rates below 5%.

How do you improve CI/CD pipeline speed?

The most impactful speed improvements are parallelizing test execution across multiple runners, implementing test splitting based on historical timing data, caching dependencies and build artifacts between runs, using incremental builds that only recompile changed modules, and running only affected tests based on code change analysis. Together these usually take a pipeline from tens of minutes to single digits. Fast pipelines directly improve developer productivity and deployment frequency.
