Acceptance criteria validation is that gut-check moment when you run through your finished work against the conditions everyone agreed on. It’s not just ticking boxes; it’s a conversation where the product owner or tester tests your assumptions, saying, “Does this actually do what we said it would?” Sometimes a criterion is too vague, so you have to clarify or tweak it. When every one of those statements holds true in a real scenario, you know the story is really done and ready to go live.
