ALARM FATIGUE
Every alert is still seen, but none of them is read any more.
01 DEFINITION
Condition in which the rate of state notifications exceeds the point at which each one is still attended to individually, while the cost of the one that mattered stays unchanged.
02 CONDITIONS
UNCERTAINTY
EXCESS
The number of notifications passes what judgement can absorb.
TIME PRESSURE
SUSTAINED
The pressure accumulates across a whole shift, not in a single moment.
ERROR ASYMMETRY
ASYMMETRIC
Missing the one that mattered costs more than ignoring the ninety-nine.
OPERATOR STATE
CONCURRENT
Notifications arrive while other tasks are already running.
03 WHERE IT APPEARS
MARITIMEState notifications become background sound across a long shift.
AVIATIONVariation inside the normal band is announced repeatedly and mixes with the threshold case.
LOGISTICSThroughput warnings become constant, and the exception warning is buried among them.
04 WHAT AEON WORKED THROUGH HERE
The one notification that changes the operator's next action must remain separable from the ninety-nine that do not — after eight hours, not after one.
