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 / guardrail-metric
Guardrail metric
A secondary metric that must not degrade — typically beyond a declared tolerance — even if the primary metric improves.
What this means in practice
Guardrail metrics protect against Goodhart effects where optimizing the primary metric erodes a downstream interest (latency, error rate, fairness, revenue). Distinct from `Guardrails` (LLM safety-layer controls); this is an experimentation concept.
Synonyms
guardrail KPI , guardrail indicator , protected metric
