  64. 64. ownership productivityYou choose the tools to get the agilityjob done, you support the API forothers, you own the features tomake users happier, you ensureit works, you carry the pager
  65. 65. ownership productivityBroad focus around quality, agilityquality comes from solidengineering, give time toengineers, less meetings moreget shit done
