Policies determining which source values prevail during master data consolidation.
DESCRIPTION
Survivorship rules define attribute-level criteria to select the most authoritative values when merging records. They may prioritize sources, recency, completeness, verification status, and trust. These rules are implemented in MDM platforms to produce golden records consistently. Effective rule sets balance automation with stewardship oversight to handle exceptions. Continuous tuning ensures alignment with business policies and regulatory requirements.
