Scrum QA
Scrum QA describes how testing activities integrate into the Scrum framework — participating in sprint planning, testing stories within the sprint they're built, and demonstrating tested functionality at the sprint review — rather than testing as a separate phase happening after a sprint ends.
A common anti-pattern Scrum QA specifically works to avoid is the "mini-waterfall" — development happening for most of a sprint, with testing crammed entirely into the last day or two, effectively recreating the same testing-as-a-late-phase problem Scrum was meant to solve, just compressed into a shorter cycle.
Healthy Scrum QA looks more like continuous overlap: testers write test cases from user stories during sprint planning, test features as they're completed throughout the sprint rather than waiting, and flag testing risk early enough in the sprint that there's still time to actually address it before the sprint ends.
