Why Best-in-Class Data Governance Matters

Risk

Generic data governance leaves regulators dissatisfied. Best-in-class data governance leaves audit-defensible posture.

Cost

Brownfield retrofit of data governance is 3-5x more expensive than governance-first design. EPC Group standard finding: enterprises that skip governance-first sequencing pay 200-500% more in remediation cost over 24 months.

Time

Annual third-party assessments take 8-16 weeks for governance-mature tenants vs 26-52 weeks for retrofit tenants.

Brand

Public data incidents — PHI breaches, MNPI leaks, IP theft — cause material brand damage. Best-in-class data governance prevents these incidents.
