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 / sunset-decommission-case
Sunset / decommission case
A structured argument to stop running an AI feature whose realized value no longer justifies its TCO.
What this means in practice
Essential counter to the sunk-cost fallacy; the sunset case surfaces realized-value data, retirement cost, data-retention obligations, and alternative-use-case value.
Synonyms
AI sunset case , decommission decision
