- No crying. We’ll see what’s out there, and determine that story points is the “one true way” The goal is to quickly come to a consensus How do teams make decisions?
- Vote using a show of hands: for/against Can miss potential alternatives
- Thumbs up, down, sideways (unsure) Convince the sideways thumbs

- Ultimately we need to know how big the task is so we can get to how long That’s where size comes in
- In what language? Skill level?
- Express the amount of business functionality an information system provides to a user
- Tall, grande, venti Small, medium, large Not consistent
- S, M, L, XL, XXL Size = # of days Wear a larger size, don’t remember the feel of the previous
- Can’t be that precise Accuracy versus precision
- Created by Mike Cohn Fun, easy, and fast Uses a defined sequence of numbers
- How do we get from here?
- How do we determine how long? What people really want to know
- Story points measure size, risk, “bigness”
- Estimate the number of sprints
- Triangulate the stories: assign a 1 and a 13 Compare all stories to these Group all like ones together and compare
