  • Organizations that feel that they desperately need to take that risk, are doing it because they disrespect their team’s time.

    Or they are aware they are not in a position to block deployments for 60 hours every week? I’ve felt more discouraged working at companies that blocked Friday deployments because “it could wait until Monday”, and then when Monday came half of the team was blocked or waiting for some new data report that could have been running during the weekend.

    It can be the smallest risk in the world, but it’s still a risk.

    And it’s up to the Engineering manager (or at least the Release Manager in places where that role still exists) to evaluate what would be the trade-off. If you say that a bug coming from a Thursday deployment could’ve waited until Monday, why can’t a bug that has come from a Friday deployment?

    I guess my issue is not in saying “Some things should not be deployed on a Friday”, but with the generalization. Of course there are things that should be okay to deploy on a Friday, or a Thursday night, or when the manager is on vacation… Being strict about it seems anything but “respect for the team”, but a general distrust of the people and the process.


  • Every change that isn’t already an active disaster recovery can wait for Monday.

    I honestly fail to see the difference between “don’t deploy on Friday if this can wait until Monday” and “don’t deploy on the evening if it can wait until the next morning”.

    The idea of CD is that changes are small and cheap. No one is saying “it’s okay to push huge PRs with huge database migrations on a Friday”, what is being said is “if your team is used to ship frequently and incrementally, it won’t matter when you ship and your risk will always be small.”





  • The author ended up creating a strawman. Allen’s argument was pretty clear: if your deltas are small and your deploy system is fully automated, then no one should be afraid of the risk of deploying.

    Given that, if I deploy on a Monday morning and there is a bug on the new release, you revert, reproduce the issue in staging and push only new code when it is fixed. Same thing if I were deploying on a Thursday afternoon or a Friday at 7PM.
