Ice Breaker STEP 1: • Self-introduction Mind Map • Central Image – Your name and your Icon • BOI’s may be, but not have to be; – Why ? (you come here) – What ? (do you do) – Favorites • Leave the other side of the card blank ! 22 Seeing is understanding.
Ice Breaker STEP 2: • Your Name and Icon (again) in the lower half of the back side. 23 Seeing is understanding.

User Stories: Ron Jeffries’ 3 Cs • Card – Written on note cards. – Cards may be annotated with estimates, notes, etc. • Conversation – Details behind the story come out during conversation with customer • Confirm – Acceptance tests confirm the story was coded correctly 25 Seeing is understanding.
User Stories: Mike Cohn • Shift focus from writing to talking • Metaphor of Trawling (by Suzanne and James Robertson) – Requirements can be captured with different sized nets – Requirements change, mature, possibly die – Skill is a factor • Avoid “The user”, find “Roles” • In order to <benefit>, as a <role>, I want to <story>. 26 Seeing is understanding.
Why Mind Map and User Stories Fit ? • Shift focus from writing to talking • Trawl requirements with coarse sized net first • Capture Emotion, Use your right brain ! Colors, and Pictures ! – To fully utilize broadband communication and preserve it in your brain, as the same time, keep it into a mind map as a memento of the situation. In the future conversation, you can use it to resume the context back. 27 Seeing is understanding.
