Most teams do not lack testing so much as lack trust in it. A suite that fails randomly gets ignored, and an ignored suite is worse than none, it costs time and buys no confidence. Our first job is usually making the existing tests reliable enough that a red build actually means something.
From there we work on coverage where it pays: the flows that carry revenue, the edge cases that generate support tickets, the regressions that have already happened once. Not every line needs a test, and chasing a coverage percentage is a good way to write a lot of tests that assert nothing.
QA also means the parts people forget — accessibility, performance under realistic load, and behaviour on the devices your users actually own. We fold those into the same pipeline rather than treating them as a pre-launch audit.
