5. jgs Writing Stories

6. jgs 0516 0100 Key Idea Do not assume that you

   know what’s best (ignoring the user) § A) Ask question § B) Clarify § C) Two heads are better than one (you are a team)

8. jgs 0516 0100 Storyboarding storyboard Who? What (What if)?, why?,

   time

9. jgs 0516 0100 Storyboarding storyboard A C … Z B

   Who? What (What if)?, why?, time

10. jgs 0516 0100 Ideas (not mandatory as a diagram)

11. jgs 0516 0100 Storyboarding storyboard A C … Z B

    Who? What (What if)?, why?, time • As a player, I want to see ghosts moving… • As a ghost, I want to move…

12. jgs 0516 0100 Template § As a <role> § I

14. jgs Epics and Stories

15. jgs 0516 0100 PBI § Product Backlog Item (PBI)= a

    desirable business value = § PBI are documented as user story Large PBI Small and detailed PBI Small and detailed PBI Small and detailed PBI Sprint PBI Sprint PBI Sprint PBI Sprint PBI Sprint PBI Sprint PBI (1) Design, Build, and Test (2) Knowledge-acquisition Epic Release (weeks) Story A user story (days) Feature / Theme Sprint (weeks) Task (hours)

16. jgs 0516 0100 Epics vs Stories agilevelocity.com

17. jgs 0516 0100 Key Idea https://www.pinterest.com/adamp3/inspiration/ Manifesto: The goal is
