CONCEPT
Weak Signal
The small, ambiguous, inconsistent cue that precedes catastrophic failure — available in the data but systematically disadvantaged in organizational sensemaking unless practices exist to surface it.
Every organizational disaster
Weick and Sutcliffe studied was preceded by weak signals that were available but not extracted. The nurse at
Bristol Royal Infirmary who kept the private tally of pediatric cardiac mortality. The engineer who questioned the O-ring performance before Challenger. The co-pilot at Tenerife who hesitated before the captain's takeoff. In each case, the signal was present. The information existed. What was missing was the organizational capacity to extract the signal as meaningful rather than as
noise, to amplify it against the prevailing interpretation, and to incorporate it into collective action before the consequences became irreversible. Weak signals are structurally disadvantaged in
sensemaking: they are small, they are ambiguous, they are inconsistent with established patterns, and they typically come from people without institutional authority. The capacity to attend to weak signals is the core of
organizational mindfulness, and it is precisely the capacity AI threatens to atrophy — both by filtering signals through its own pattern-recognition biases and by eliminating the developmental
friction through which practitioners
