How do you Analyse a user story?
User story analysis (or USA for short… actually I think that one's already taken) is where you get together the product owner, developer and tester together to discuss a user story (or requirement) before any of the code has been written for that functionality.
What makes a good user story?
The story always elaborates an advantage for the user, customer or client. The story is quantifiable: it has enough concrete detail to enable an experienced team to appreciate its scope. The story is the right size. The story contains enough information to allow it to be tested.
