COMMON REFERENCE DRIFT
They agreed on a common point, and each has moved theirs since.
01 DEFINITION
Condition in which parties coordinate against a shared reference that each keeps locally, so the reference stops being common through ordinary correction and the divergence is invisible from inside any of them.
02 CONDITIONS
UNCERTAINTY
CONFLICTING
Each party holds a reference it believes is the shared one.
TIME PRESSURE
LOW
The divergence accumulates slowly and no single correction is wrong.
ERROR ASYMMETRY
DEFERRED
The drift costs nothing until two parties coordinate closely enough to feel it.
OPERATOR STATE
SUPERVISORY
The person is coordinating against something they are not looking at directly.
03 WHERE IT APPEARS
ENERGYParties coordinate against a time base each keeps and each corrects independently.
CONSTRUCTIONSetting-out relies on a datum that each contractor has re-established locally.
MANUFACTURINGCalibration references are maintained per line against a standard that was once one standard.
FINANCEValuations rest on a reference each desk keeps current in its own way.
LOGISTICSSchedules coordinate against a clock each site maintains for itself.
MEDICALMeasurements are compared against ranges each unit has adjusted for its own population.
04 WHERE THIS IS SURFACING
This surfaces wherever coordination rests on an agreed origin — a time, a datum, a version. Each party keeps it accurate for itself, and the accuracy is what separates them.
The question it keeps returning to is what a shared reference has to give up to stay shared — one nobody may adjust is one that is wrong for everybody, and one each may adjust stops being shared the first time anyone does.
