Without dramatizing events like covid-19, any kind of crises, volcanic eruptions or economic downturn, it's true that once they're over: You always know more with the wisdom of hindsight.
What about trying a different approach for once? What about simulating a crisis? Does everyone know which lever to activate, which strings to pull and which customers need to be contacted now?
Errors made in the simulation would have lost a lot of money, reputation or employees in a real crisis. We think going through the ropes is useful. Why else would cruise ships repeatedly simulate emergencies?
After the experience of the Corona crisis, we are certain that everyone has a strict stress test and the associated administrative plan in the drawer.
