• The Planning Game
  • Customer identifies "stories" (features)
  • Developer estimates scope quickly
  • Customer sets priorities and features, respecting time estimates
• Short Releases
  • Initial system released very quickly (but perhaps with few features)
  • New releases on a very short cycle
  • Each release considered a prototype for next release
• Metaphor
  • Informal metaphor provides direction, vision
  • Formal specification takes too long
    and likely to change anyhow
• Simple Design
  • Address all requirements
  • Do not anticipate future needs
  • Be as simple as possible
