Obliterate toil: automate it.
Automate ruthlessly. This is where I have seen the most surprising pushback. We’re programmers. Automating processes is what we do! People will flinch about this, afraid of time spent automating things that won’t pay off. Yes, we’ve all been there. So don’t do that. Don’t automate things that are really one-offs. If there’s any chance you have to do the same thing more than five times, automate it. If it’s complex and difficult for a human to do, automate it. If the blast radius of the explosion caused by a human doing it wrong is large, automate it. If the end results need to be the same every time, automate it.
Infrastructure should be automated as far as you can push it.
The upside of automation is that the software that does the work for you can be instrumented.
