Time to bake
Code that matters needs time to bake.
I don’t care that it passed all your unit tests. Or integration tests.
I don’t care that it worked in simulation.
The code isn’t done. It still has bugs. It isn’t ready for production.
You shouldn’t be so quick to send that email telling everyone how awesome you are.
Let it bake. Be quiet. The issues will come. Expect to turn the new feature off.
You have a flag for that, right?
Be prepared to revert. Flags don’t always cover everything.
Fix the issues. Try again.
Sometimes you don’t even have to wait for the issues to show up. Your brain will figure them out on its own as you sleep.
Eventually the code will be good enough to rely on.
Give the code time to bake.
