Most teams don't notice their CI/CD pipeline is broken — they just notice that deploys "feel slow" and shrug it off as normal. It isn't. A pipeline that takes 25 minutes to ship a one-line copy change isn't a fact of life, it's a symptom.
Here are the mistakes we see most often when reviewing pipelines — roughly in order of how much time they silently burn.
1. Running the full test suite on every single change
If a developer fixes a typo in a README and the pipeline still runs the entire integration suite, database migrations, and end-to-end tests, you're paying full price for a change that touched nothing critical.
Fix: split your pipeline into stages based on what actually changed. Path-based triggers (only run frontend tests if frontend files changed) and a fast "smoke test" tier before the full suite can cut average pipeline time dramatically without sacrificing safety.
