COMPEL Glossary / drift-value-drift

Drift (value drift)

Erosion of delivered value over time due to changes in data, model, user behaviour, or environment — distinct from data drift (input distribution) and concept drift (relationship change) because its surface is the value metric itself.

What this means in practice

Monitored via value-realization cadence; triggers recalibration of the business case.

Synonyms

value drift , realization drift
