  14. heroku create -s cedar mystaging-app git remote add staging [email protected]:heroku/...

    git push staging master git push production master Defined Contract/API Developer environments Environment parity
  15. production = staging = dev minimized divergence enables continuous deployment

    Defined Contract/API Developer environments Environment parity

    job done, you support the API for others, you own the features to make users happier, you ensure it works, you carry the pager
  22. ownership productivity agility Broad focus around quality, quality comes from

    solid engineering, give time to engineers, less meetings more get shit done
  23. ownership productivity agility Iterate fast and often, a failed attempt

    is a successful experiment, culture around seeing/doing over talking
