The COMPEL Glossary Graph visualizes relationships between framework terminology, showing how concepts interconnect across domains, stages, and pillars. Term nodes cluster by pillar affiliation while cross-references reveal semantic dependencies — for example, how risk appetite connects to control effectiveness, model governance, and assurance requirements. This network representation helps practitioners navigate the framework vocabulary and understand that COMPEL terminology forms a coherent conceptual system rather than isolated definitions.
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
