Related: marketing data layer

Governance defines who owns KPIs; the marketing warehouse describes how data flows from GA4, Ads and CRM into BigQuery and BI.

Marketing data resources hub (warehouse checklist, BigQuery calculator, BI catalog) adds the technical layer to DG materials.

Practical example (e-commerce, anonymised)

Online retail · ~€12M GMV · 4 data systems

Problem: marketing reported GA4 conversions 18% higher than sales from ERP; product had three IDs (shop SKU, EAN, wholesale index); no owner of the “active customer” definition.

  • Week 1-2: DG checklist (score 42%), system map, 8 shared KPIs in glossary.
  • Week 3-6: GA4 transaction_id ↔ orders mapping, CRM deduplication rules.
  • Week 7-12: data quality dashboard in Power BI, monthly Data Governance Council rhythm.

Result after 3 months: one weekly KPI report accepted by leadership; ~40% fewer parallel Excel reports.
