Semantic-Layer Governance & Data Contracts

Context

With many brands, markets and sources, the same KPI can be defined differently in every dashboard unless definitions are governed centrally.

Scope

• KPI definitions and metric governance
• Semantic models
• Data contracts
• Source-specific transformation standards
• Executive reporting consistency

Approach

Create a governed measurement layer that separates business definitions from individual dashboards and analyses. Definitions live once in the semantic layer; transformation layers follow source-specific standards; data contracts make the expectations between layers explicit.

Purpose

• Consistent metric definitions across 22+ transformation layers and approximately 45 semantic models.
• Executive reporting that reconciles across brands and markets.
• A governed foundation for self-service and AI-enabled analytics.
