Pre-COVID, our office building in Tokyo organized a disaster-preparation day every year. This was run by the building management team, which politely informed every corporate tenant in the office section that, yes, they would be participating.

Sure, we all knew when the drill would be so we could adjust our schedules, but the actual alarms did sound, and the entire building evacuated, which included climbing down something like fifty flights of stairs with your emergency bag -- mandated by law in Japan -- in-hand, plus (optionally) using a fire extinguisher on a pretend fire after you got outside.

Sure, the extinguishers were just pressurized water, and you were spraying at a metal target, but you still had to pull the pin, squeeze, and aim, and they were at full pressure.

Was a good reminder that it's way better to have your first experience with stuff like a fire extinguisher happen under controlled conditions, as opposed to having to figure things out before your kitchen fire gets out-of-hand and burns down the house.

Same goes for radio, changing tires on a car with the provided jack, and so on.

Preparedness is 90% "knowing what to do" and 10% "having the right tools for the job".

There's a galactic difference between just reading about it and actually experiencing it even just once.

Essentially the difference between being book smart vs. street wise.

“We don't rise to the level of our expectations, we fall to the level of our training.” Reading about it generates expectations, and they can be deadly.

On average we fall to the level of our training, but then there's moment to moment variation because of "human error" which has little to do with lack of skill or training, and more to do with individual and situational factors.

Training is critical, but even then you can still fail, which is why layers of backups are great.

For a lot of us, skill might never be as reliable as other layers, but it's generally different from other layers making it less likely to fail at the same time because of the same cause.

Crew Resource Management has a lot of great insights.
