Well crafted user stories articulate the features that make up your product vision in a way that focuses on the measurable value to deliver, rather than a specific design or implementation approach. They are a starting point for design (how should it work?), test-driven development (did we build it right?), and how you will measure success (did we do the right thing?).
|Typical Length||1-2 weeks; ongoing during agile development to refine, add, and remove stories as needed|
