QA in Agile: More Than "Test at the End"

The biggest shift agile brought to QA was timing. In waterfall, testing happened after development was "done." In agile, testing is woven into every sprint, every story, every conversation. A QA engineer in an agile team is not a gatekeeper who approves or rejects work at the end -- they are a quality advocate who shapes how work is defined, built, and verified from the start.
