I often find that my user stories are too vague, leading to "scope creep" during the sprint. How can I structure my Acceptance Criteria to be specific enough for developers but still readable for business users? Are you using Gherkin (Given/When/Then) for everything, or do you reserve that for technical stories? I need a format that prevents misinterpretation of our pricing logic.

For complex business rules like pricing logic, Gherkin is actually the best "bridge" language. It forces you to think through every scenario (the "When") and the expected outcome (the "Then"). If Gherkin feels too technical for your business users, try a "Checklist" format for the main story and use Gherkin only for the detailed scenarios in a linked document or a specific Jira field. The key to preventing scope creep is the "Definition of Ready." Never let a story into a sprint unless the AC are binary—meaning they can clearly be marked as "Pass" or "Fail" without any subjective interpretation by the QA team.
Are you involving your QA engineers when you write these, or are you handing them over as a finished product right before the sprint?
Try using "Decision Tables" for pricing logic. It’s a much more compact way to show multiple variables and their outcomes than writing twenty separate user stories.
Maria is spot on. Decision tables are a lifesaver for complex logic; they make it impossible to miss an "Else" condition that might break the system.
Kevin, that’s where I’ve been failing. I usually write them in a vacuum and then "present" them. After your question, I realize I should be doing a "Three Amigos" session—BA, Dev, and QA—to refine the AC together. If the QA engineer can’t figure out how to test the criteria, it’s a sign that I haven't been specific enough. I'm going to start scheduling 15-minute syncs for each high-complexity story to ensure the "testability" is baked in from the start.
