Lesser known trick: reorganize your teams so the code isn’t batshit.

That does imply that the people in the business with the authority to do that know how to do that and they in my experience don't - they can't solve a problem they don't understand and are unwilling to delegate it to someone who can understand it.

The same pattern repeats across multiple companies - it comes down to trust and delegation, if the people with the power are unwilling to delegate bad things happen.
