An industry secret
For all the automation the technology industry prides itself in there’s still a lot of it that’s manual. Some companies get up on stage and talk about how great their automatic canary deployments are, how they use feature flags, or a variety of different methods to get their products to market.
I’ve been a part of some large product launches and plenty of incremental changes in various environments. As soon as the product launch requires coordinating with a non-development team (e.g. blog post or press release) they all had some form of a slack channel, email list, or phone bridge where someone was in charge of manually going down a spreadsheet and clicking buttons.
This is fine. Not everything has to be automated. You’re not doing it wrong. Sometimes the right thing to do is manually get acknowledgements from all stakeholders and click a button.
