Acceptance criteria are the most important and most commonly miswritten section of any PRD. 68% of engineering re-requests trace back to missing or vague acceptance criteria (Scriptonia, 2026). These 25 examples show the difference between criteria that eliminate ambiguity and criteria that create it.
"Good acceptance criteria read like test cases. If a QA engineer can write an automated test from reading your criterion, it's specific enough. If they have to ask a question, it's not."
— Tomas R., QA Lead at a SaaS platform company
