This is our second Kaizen episode, where Adam, Jerod & Gerhard talk about changelog.com improvements since episode 10. OK, so Gerhard deleted the DNS API token. Not only did he take the time to understand how that happened, so that he could actually learn from his mistake, but now we have a system in place so that we can share learnings from incidents. By the way, these are publicly available in our #incidents Slack channel.

A great & unexpected thing that happened since we recorded this episode, is Jerod fixing 99% of all the errors that were happening in prod. The top error was the broken Twitter auth - sorry Matt - which was a result of us upgrading to OTP 24 a few months back. Episode 3 show notes include a YouTube stream which captures it all.

We wrap up this episode by each of us sharing the improvements that we would like to do until our next Kaizen. You heard it from Adam first: Ship It Driven Development
