2/5/12 - Terry, Joanne, Sally
IN OUT
- select friend by searching by - searching for friends by
email address name
- only show addresses of those - autocomplete when typing
that aren’t my friends already name
- confirm when I add a friend, - inviting new users to join if
only add them if I answer yes they are not members already
- back to email search results
when I answer no
- “You are now friends”
confirmation afterwards

27. Good Stories are Told,
Not Written
• Defer detail until the last responsible
moment
• Understand and solve the problem together
• Capture the conversation but keep it simple
• Define “done”
• Stop telling/start building as soon as you
have enough detail

53. To Do Doing Done

59. Reducing Cycle Time
• Build things in a way that allows people to play
earlier
• Don’t retreat to your bay in the assembly line
• Think: concurrent activities, not sequential
phases!
• Share the responsibility for getting stories to
“Done”

66. Keeping Stories On Track
• Spot the problem using statistics
• Split stories by fidelity or functionality
• Swarm to complete things faster

67. Individuals and Interactions
over Processes and Tools
