• No crying. We&#x2019;ll see what&#x2019;s out there, and determine that story points is the &#x201C;one true way&#x201D;
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
• Do you show support or resistance?
More fingers = more support or more resistance
• Ultimately we need to know how big the task is so we can get to how long
That&#x2019;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&#x2019;t remember the feel of the previous
• Can&#x2019;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, &#x201C;bigness&#x201D;
• 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
• When trying to decide between a 3 and 5, think buckets of water
• Break them down if you need to
• Play the game

• Tips: watch out for anchoring (putting a number into the team&#x2019;s heads)
• Big announcement!
• Weekly Standup - weekly 15-minute show where I&#x2019;ll answer your Agile questions, live!
