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 / primary-metric
Primary metric
The single metric whose movement drives an experiment's ship/no-ship decision.
What this means in practice
Exactly one primary metric per hypothesis reduces ambiguity; secondary metrics support understanding but do not decide. Choice of primary metric is itself a governance decision because it encodes what the organization values from the change.
Synonyms
north-star metric (experiment) , OEC (overall evaluation criterion)
