XP Practices Planning (Iteration)

Plan for one to four week time-frame Customer presents work to do More detailed estimates by developers Estimates and work velocity based on recent history Project steering every few weeks

• Cards presented in an iteration do not have to match what was estimated during a release plan.
• As we continually estimate new tasks, our recent history allows our estimates to be based on what we've learned.
• A card is "an invitation to a conversation".
