Oh, I have fixed systems like those so that everything is deterministic and you can fake the state with a reasonably low amount of effort. It solved a few very important problems.

(But mine were data integration problems. For operations interdependence ones the common advice is to write a fucking lot of observability into it. My favorite minoritary one is "don't create it". I understand there are times you can do neither.)
