Who’s the end user, and what problem are they facing? • What does success look like? How can we measure it? Intent “What are we trying to solve?” • What are the main use cases and edge cases? • What happens if the user enters invalid input? • What should not happen? Behavior “What should it do?” • Are there any business rules, validation, or dependencies? • What's out of scope? • Are there performance, security, or platform constraints? Constraints “What are the boundaries?” • What’s the acceptance criteria of the story? • Can we observe or measure the expected behavior? • How will we test it?

Risk “What could go wrong?” 2"4LJMMT"OBMZUJDBMUIJOLJOH .ZCMVFQSJOUPGRVFTUJPOTBTB2"UPDMBSJGZSFRVJSFNFOUT
