    2. Managing
      • Open work space
      • Sustainable pace
      • Stand-up meeting to start each day
      • Project Velocity is measured

    3. Designing
      • Simplicity
      • System metaphor
      • CRC cards
      • Spike solutions
      • No functionality is added early
      • Refactor
    4. Coding
      • Customer is always available
      • Code to agreed standards
      • Code the unit test first
      • Production code is pair programmed
      • One pair integrates code at a time
      • Integrate first
      • Dedicated integration computer
      • Collective ownership
    5. Testing
      • All code must have unit tests
