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 / GL-55
Bias Delta
The measured difference in a model's performance or outcome distribution across protected groups, expressed against a defined fairness threshold.
What this means in practice
Bias delta is computed per protected attribute (for example gender, age band, geography) using disparate-impact ratios, equal-opportunity gaps, or calibration differences, and is monitored over time so that drift into unfair behavior is detected before it reaches users.
Context in the COMPEL framework
A core metric of the Responsibility dimension. Captured in the Evaluate stage and reviewed in Learn; feeds fairness gates in release governance.
Where you see this
Bias Delta is most commonly referenced when teams work across the Evaluate and Learn stages — especially within the Agent Governance layer . It appears in governance artifacts, assessment instruments, and delivery playbooks wherever COMPEL is operationalized.
